Tall, young and active

November 14, 1963 was a cold morning. This was nothing out of the ordinary for the fisherman. They were used to the winter weather around Iceland. Suddenly, however, they saw something unusual. Thick, black smoke was pouring out of the sea.     1     (think) a boat was on fire, they raced toward it. Yet as they got closer, they realized it was     2     quite different. Magma (岩浆) was rubbing away from the ocean floor. The fishermen watched as a new island rose from the sea. This island, later     3     (name) Surtsey, joined the thousands of volcanic islands worldwide.

The island of Hawaii is one of the most well-known volcanic islands. Lava (熔岩) from multiple volcanoes built this island. One of these volcanoes is Mauna Kea. Mauna Kea began under the ocean over 1 million years ago. Magma broke through the Earth’s crust- that is, the outer layer of the earth.     4     the magma cooled, it formed an underwater mountain. About 100,000 years ago, the mountain rose     5     sea level. Eruption (喷发) then became more frequent and more violent. Layers of lava hardened into rock. Now, Mauna Kea     6     (measure) 9,966 meters from ocean floor to mountain peak, making it the world’s highest mountain.

Fortunately for Hawaiians, Mauna Kea volcano is quiet - for the time being.     7     volcano on the same island is anything but quiet. Kilauea is smaller than Mauna Kea. However, it has erupted nonstop since 1983 and is the world’s most active volcano,     8     produces between 300,000 and 600,000 m2 of lava every day. Over the past two decades. It     9     (add) more than 540 acres to the island. In spite of the danger, it is a popular tourist attraction. Yet,     10     this popular tourist attraction contributes to the Hawaiian economy financially also comes at a cost. Kilauea is responsible for taking both lives and homes.

2 . Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.

There are many reasons why some cats are bad-tempered; their temperament can be influenced by their upbringing or they are simply born that way. However, even the sweetest, most affectionate cats can suddenly become bad-tempered and behave out of character. According to veterinarian Dr Katrina Warren, the problem can generally be solved, but you’ll need to look for underlying issues.

Changes in a cat’s behaviour can often be explained by a health problem. Pain can cause cats to behave very differently, and it’s easy to mistake a problem as behavioural, when in fact it is medical. Should you observe a significant change in your cat’s behaviour, then a visit to the vet is the best place to start? Watch out for changes in eating, drinking or litter-box habits. Also hiding and avoiding being touched. Be sure to report all changes to your vet. There are many cat health problems that can be readily treated to ease symptoms and pain for your cat.

It pays to remember that cats don’t like to share or queue. Sharing of ‘resources’ such as litter trays and foodbowls can cause stress and anxiety for many cats. It’s always a good idea to provide each cat with their own litter box, food, water bowls and bed as a minimum. One litter box for each cat plus a spare is even better, as are multiple sleeping spots and extra scratching posts. A lack of space to hide from or avoid other cats, competition for territory and lack of individual attention can also add to household friction. If your cat is feeling anxious, offering it an elevated place to sit, such as a climbing tree, can be helpful.

Moving to a new house, the arrival of a new baby, new pets and other types of change can seriously impact cat behaviour. Cats are creatures of habit and tend to be territorial, so a change in routine may cause them to react in a number of ways, including withdrawal or aggression. Try to keep your cat’s environment as calm as possible and make sure there are places where they feel safe. Sometimes confining them to a single room with a litter box, bedding and home comforts can help them to settle.

Some cats simply do not like being touched and handled. These are often cats that received limited socialisation with humans when they were kittens. These cats do best in a quiet household without children and need understanding and patience to help build their confidence.

3 . Huizhou Architecture Comes to Life

Huizhou has a long history. When successful Huizhou businessmen got old,they often went back to their hometown and built houses to spend their remaining years.    1    Now, walking along the bluestone streets there,visitors can appreciate the distinctive Huizhou-style houses,featuring white walls,dark tiles (瓦片) and layered horse-head roofs, and feel like they are lost in a traditional Chinese ink painting.

Huizhou architecture, with its long tradition and great diversity, occupies an important place in Chinese architectural landscape, says Zhang Wangnan, director of the China Huizhou Culture Museum in Huangshan. Huizhou houses tend to be built on the natural places, since Huizhou is a mountainous area with few flat areas of land, according to Zhang. Moreover, daylight is valued in Huizhou houses, reflected in the building of open interior courtyards, allowing sunshine to enter the rooms. “Huizhou businessmen also believed that water symbolizes wealth.    2    It stands for keeping windfall profits,” says Zhang.

Huizhou is famous for its stone, wood and brick carvings, which are widely used to decorate local houses. “    3    In this way,they integrate their aesthetic (审美) values and emotions into the buildings,making them more beautiftul and educating their children through the meanings contained in the patterns,” says Zhang.

    4     “If you look at the outside of a Huizhou house, it seems simple, enclosed by walls, but the insides are open and broad, with complicated decorations. It is just like Huizhou people, who are often reserved toward strangers but friendly when you get to know them.” says Zhang. He also says that Ming houses differ from those of the QingDynasty in many aspects, for example, having fewer horse-head roofs and less complicated carvings.

A.When it rains, water falling on the roof soon flows to the courtyard.
B.Many of their houses are well-preserved today, especially in Xidi and Hongcun.
C.To talk about Huizhou culture, we must first understand Huizhou.
D.People carved beautiful patterns and historical stories on the walls, windows and wooden posts of their houses.
E.Features of Huizhou houses display the characteristics of local people.
F.Huizhou people have established many schools in the field of culture.

4 . The Apollo Missions


“That's one small step for a man. One giant leap for mankind.”

Neil Armstrong

Apollo’s Goals

The national effort that enabled Astronaut Neil Armstrong to speak those words as he stepped onto the lunar surface fulfilled a dream as old as humanity. Project Apollo’s goals went beyond landing Americans on the moon and returning them safely to Earth.

Apollo 13


Apollo 13 has been called a “successful failure,” because the crew never landed on the Moon, but they made it home safely after an explosion crippled their ship. When the associated heater was turned on during flight, the tank exploded depleting almost all of the power from the command module and forcing the crew to use the lunar module as a lifeboat. Jim Lovell, Fred Haise and Jack Swigert came home safely thanks to the mission control team’s improvised procedures and their own ability to implement them.(Launch: April 11, 1970; splashdown: April 17)

Apollo 14


Notable for the return of America’s first astronaut, Alan Shepard, to space, Apollo 14 also was probably the smoothest lunar landing to that point. The crew spent more than nine hours outside the lunar module and set up a number of experiments. Shepard set a new distance record by walking more than 9,000 feet on the lunar surface, pulling a hand cart to carry their tools and samples.(Launch: Jan. 31, 1971: lunar landing: Feb. 5: splashdown, Feb. 9)

Apollo 15

For the first time, humans drove a car on the Moon. The first of the Apollo “J” Missions-designed for longer stays on the Moon - the mission carried a lunar rover, which Commander David Scott and Lunar Module Pilot James Irwin used while they were on the surface for more than I8 hours. They traveled more than 17 miles in the rover, setting up experiments and collecting 170 pounds of samples. Before leaving the lunar surface, Scott conducted an experiment to test Galileo’s theory that objects in vacuum, without air resistance, would fall at the same rate. He dropped a geological hammer and a feather, which hit the ground at the same time, proving Galileo right.(Launch: July 26, 1971, lunar landing: July 30: splashdown: Aug. 7)

1. Why has Apollo 13 been called a “successful failure”?
A.Apollo 13 finally exploded as planned in space.
B.All the crew succeeded in landing on the Moon.
C.The crew managed to escape from a severe accident and returned to Earth.
D.The crew finished the experiment although they failed to land on the Moon.
2. Which of the following is True according to the passage?
A.It took five days for Apollo 14 to reach the Moon.
B.The lunar rover was used as a lifeboat for space travel.
C.Shepard tested Galileo’s theory successfully on the Moon.
D.Apollo 15 remained in space for the shortest period of time.
3. Which of the following column is this article most likely to be found?
A.Booming ScienceB.Exploring the Unknown
C.Mechanical WorldD.Transforming Moon

5 . In February 1970, a group of activists gathered in Vancouver, Canada to discuss a planned nuclear test on the Alaskan island of Amchitka. They eventually agreed to sail to the test site and _________ against the explosion in person. At the end of the meeting, the chairman raised two fingers to the room and shouted “Peace!”. After a brief pause, one young attendee _________ with a monumental line: “Let’s make that a green peace”. The group were so _________ the phrase that they named their first boat the Green Peace.

Over the last 50 years, the _________ movement has become so closely associated with the colour green that it’s almost impossible to see a green poster, label or recycling bag without thinking about our planet’s future. But though that connection is the product of a very recent crisis, its _________ go back some way. We have _________ green with nature and its processes for thousands of years. Indeed, the very word “green” comes from the ancient Proto-Indo-European word ghre, meaning “grow”.

The human species, which emerged in the green forests and grasslands of Africa about 300, 000 years ago, has a special _________ link with green. Our eyes might even have _________ specifically to see the green in plants. Unlike most animals, who are red-green colour blind, we humans developed a third cone cell, an additional photoreceptor enabling our _________ to spot ripe red and yellow fruits against a backdrop of green leaf, and to distinguish different green leaves from each other. In daylight conditions, human eyes are more ____________ to green than any other colour.

With the rise of farming, we started to use green as a(n) ____________ for nature and its processes. Archaeologists have recently found an extraordinary store of green jewels in the Levant, ____________ some 10, 000 years. The researchers believe that these objects, many of which had come from hundreds of miles away at great cost, were chosen because they ____________ young leaves and might have been used by early farmers to pray for rainfall or fertilise crops.

The ancient Egyptians, who were farming the banks of the Nile from about 8000 B.C., ____________ use green as identification for their crops. Egyptian painters often represented their god of ____________, Osiris — who was responsible for flooding the Nile’s banks, filling the soil with nutrients and pushing the first green shoots up through the fields — as a bright green being.

文章大意:这是一篇说明文。文章讲述了在过去两年的大力推广和广泛参与下,垃圾分类已成为一种新趋势,重塑了整个北京校园的形象。

6 . With vigorous promotion and extensive participation over the past two years, waste sorting is a new trend that has reshaped the image of campuses across Beijing.

“In the past, sanitation workers sorted the garbage next to the trash cans near the dormitory, _________ a disgusting odor. On windy days, the trash was blown everywhere and we always _________ around it with our hands covering our noses,” says Sun Jiajing, a sophomore at Beijing Forestry University. “Now, we are more active in classifying waste.”

Since a revised guideline on household waste disposal in Beijing was _________ on May 1, 2020, many students have seen their campuses take on a new look that is more pleasant, tidy and appealing.

At Beijing Forestry University, about one in four students are trash-sorting volunteers.

In the Beijing No 20 High School, bins to recycle waste are placed on each floor and students on duty will set their wits to turning trash into _________.

“I received training on trash classification before taking on the role as head of the trash-sorting station. My job is to remind everyone to classify waste and recycle to the best _________,” says Ding Shuyi, a student at the school.

As China pushes _________ the “double reduction” education policy, which aims to ease the burden of _________ homework and off-campus tutoring for primary and middle school students, understanding of waste sorting has been fused into academic teaching via various innovative approaches.

“Our Chinese teachers encourage students to write poetries _________ on waste classification, math teachers lead them to do math on topics such as water conservation, while our music teachers choreographed a ‘waste sorting’ dance with the students,” says Zuo Chunyun, principal of a primary school in the suburban Tongzhou district of the capital.

Zuo adds that students in senior classes will join trash-sorting projects and map out _________ in the form of handwritten newspapers and mind maps. Decorations made from recycled materials are exhibited in the school’s corridors.

The same scene can be seen in Qianjin Primary School, Haidian district. “Garbage can be turned into __________,” says Wang Liping, the principal. “We have raised 100,000 yuan ($15,760) of charity funds by encouraging students and their parents to recycle waste, and the money was used to purchase movie screens for schools in Hotan, Xinjiang.”

According to Liu Jianguo, a professor at Tsinghua University, the implementation of garbage sorting depends on the __________ participation and unremitting efforts of society, which is conducive to the__________ of social civilization.

“Wide participation of students and school staff will help promote garbage sorting to become a new fashion in society,” adds Liu.

Official data shows that over 90 percent of the residents in Beijing have participated in waste classification, and about 85 percent can __________ categorize the garbage. But still, relevant departments are __________ to further raise the ratio.

“Our next move will be more precise supervision of groups that did __________ poorer jobs in sorting out garbage,” says a staffer with the Beijing Municipal Commission of Urban Management.

7 . During those barren winter months, with windows overlooking long-dead gardens, leafless trees, and lawns that seem to have an ashy look about them, nothing calms the uneasy nerves more than the vibrant green of plants surrounding the living spaces of one’s home. People browse through garden stores just to get a smell of chlorophyll (叶绿素) and to choose a plant or two to bring spring back into their winter-gray lives.

Now there is even more of a need for “the green,” in light of recent articles warning us of the dangers of chemicals that we, ourselves, introduce into our homes. Each time we bring clothes home from the cleaners, we release those chemicals into the closed-in air of our homes. Every cleanser releases its own kind of fumes.

Some of the chemicals are formaldehyde (甲醛), chlorine, benzene, styrene, etc. Read the labels on many home products, the ingredients aren’t even listed! During the winter, when those same windows are shut tight, we breathe in these chemicals—causing symptoms much like allergies (过敏). In fact, most people probably dismiss the effects of these chemicals simply as some allergy or other. The truth is that we are experiencing a syndrome that is called Multiple Chemical Sensitivity. Now, what has this got to do with green plants? Everything healthy! Research has been conducted with two types of plants that have actually removed much of these harmful chemicals from the air.

The two plants that seem to be the best bet for ridding one’s home of such chemicals are ferns (蕨类植物) and palms. These plants release moisture as part of photosynthesis and, as they do, pull chemicals from the air into their leaves. Even NASA has conducted some greenhouse experiments for long-term space exploration. Within hours, their plants [palms] had removed almost all traces of formaldehyde in the room. Both species of plants are ancient, dating back more than a hundred million years. Another trait they share is that they both live long lives, 100 years or more. This we expect from trees, but ferns and palms are plants; plants that can grow to 65 feet in the proper setting! Even their individual leaves live for one to two years [ferns] and one to nine years [palms]. Perhaps it is their primary qualities that have contributed to their ability to purify their environment.

1. Why does the author think we are in greater need of “the green” in our homes?
A.To bring our long-dead gardens back to life.
B.To get rid of harmful chemicals trapped there.
C.To make us feel calmer and less worried.
D.To serve as decorations as well as refresh us.
2. According to the passage, which of the following statement is TRUE?
A.The source of these chemicals released in our homes hasn’t been identified.
B.The chemicals can be removed immediately the two plants are put into use.
C.People tend to underestimate the effects of the chemical in the closed-in places.
D.People usually buy household products without referring to the ingredients on them.
3. As for the two plants, their primary qualities friendly to indoor environment include _____________.
A.the ability to absorb chemicals and live long
B.their adaptability to indoor environment
C.the fast growth and attractiveness of their leaves
D.the release of their moisture and fumes
4. Which of the following may serve as the best title of the passage?
A.Research in the New Millennium
B.Common Houseplants May Purify Your Home
C.Hidden Dangers in Your Home
D.NASA Experiment Finds the Cure

文章大意:这是一篇说明文。文章介绍了格陵兰冰盖的快速融化现象,说明地球正在变暖。

8 . The water off the coast of northwest Greenland is a glass-like calm, but the puddles (水坑) on the region’s icebergs are a sign that a transformation is underway higher on the ice sheet.

Several days of unusually warm weather in northern Greenland have caused rapid melting, made visible by the rivers of meltwater rushing into the ocean. Temperatures have been running around 60 degrees Fahrenheit — 10 degrees warmer than normal for this time of year, scientists said.

The amount of ice that melted in Greenland between July 15 and 17 this year alone — 6 billion tons of water per day — would be enough to fill 7.2 million Olympic-sized swimming pools, according to data from the US National Snow and Ice Data Center.

Each summer, scientists worry that they will see a repeat of the record melting that occurred in 2019, when 532 billion tons of ice flowed out into the sea. An unexpectedly hot spring and a July heat wave that year caused almost the entire ice sheet’s surface to melt. Global sea level rose permanently by 1.5 millimeters as a result.

Greenland holds enough ice — if it all melted — to lift sea level by 7.5 meters around the world. The latest research points to a more and more threatening situation on the Northern Hemisphere’s iciest island.

Unprecedented (史无前例的)” rates of melting have been observed at the bottom of the Greenland ice sheet, a study published in February found, caused by huge quantities of meltwater flowing down from the surface. This water is particularly concerning because it can destabilize the sheet above it and could lead to a massive, rapid loss of ice.

And in 2020, scientists found that Greenland’s ice sheet had melted beyond the point of no return. The rate of melting in recent years exceeds anything Greenland has experienced in the last 12,000 years, another study found — and enough to cause measurable change in the gravitational field over Greenland.

At the East Greenland Ice-core Project — or EastGRIP — research camp in northwest Greenland, the work of scientists to understand the impact of climate change is being affected by climate change itself.

Aslak Grinsted, a climate scientist at the University of Copenhagen’s Niels Bohr Institute, said that they have been trying to get flights into the camp but the warmth is destabilizing the landing site.

Before human-caused climate change kicked in, temperatures near 32 degrees Fahrenheit there were unheard of. But since the 1980s, this region has warmed by around 1.5 degrees Fahrenheit per decade — four times faster than the global pace — making it all the more likely that temperatures will cross the melting point.

1. The passage is mainly written to ________.
A.alert people to the rapid melting of Greenland’s ice sheet
B.arouse people’s awareness of protecting the environment
C.inform people of the large amount of ice Greenland holds
D.reveal to people the cause and effect of the rise in sea level
2. What does “a transformation” in the first paragraph refer to?
A.Climate change.B.A rise in sea level.
C.Global warming.D.The melting of ice.
3. What can be learned about the ice that melted in 2019?
A.It repeated a record melting of the ice sheet several years ago.
B.Its amount was the largest ever and lifted sea level permanently.
C.It was enough to fill 7.2 million Olympic-sized swimming pools.
D.Its melting rate was so rapid as to result in an unexpectedly hot spring.
4. It is implied in the passage that ________.
A.climate change is a result of human activities
B.the study of climate change is being made easier
C.the melting of Greenland’s ice sheet is reversible
D.temperatures increase 1.5°F or so each decade globally

9 . Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.

Should Hand Feeding Dolphins Be Encouraged?

Some tourist centers train Indo-Pacific bottlenose dolphins to approach beachside public sighting areas or boats by hand-feeding them small amounts of fish every day. Because hand-fed males aggressively attack each other over the food, putting themselves and nearby humans in danger, tourist centers focus their hand feeding only on female dolphins, says Valerie Senigaglia at Murdoch University in Perth, Australia

But recent studies have shown that only 38% of the calves (崽) of hand-fed wild dolphins survive to three years of age, which is much lower than the average 77% survival rate for wild calves in general. To better understand why, Senigaglia and her colleagues evaluated the social behavior of dolphins around the Bunbury coast in Western Australia. In particular, they observed the individual behavior and movement of 35 dolphins, including 13 that had been hand-fed using a small boat. They regularly followed each dolphin for periods lasting from 20 minutes to 3 hours for two years in a row for a total of 180 hours.

They found that hand-fed dolphins swam in relatively large groups, but more readily broke away from them to join different ones. In general, they created weak ties with other group members. “You can feel lonely in a room full of people and it’s the same thing for dolphins,” says Senigaglia. Free-swimming dolphins that are fed by hand become less socially involved with their peers. As a result, their calves may grow up lacking vital social skills-which could explain, at least in part, why they are twice as likely to die before reaching adulthood as wild calves generally.

No wonder animal right activists are calling on the practice of hand-feeding dolphins to be stopped.

Here’s to guilt-free flying

Maj a Rosen gave up flying a decade ago out of concern for its environmental impact. But when she became a mother and started hanging out with other parents, she didn’t bring it up, even when the conversation turned to flying. It would have     1     the mood.

Then in April 2018, her home country of Sweden     2     a tax on aviation (飞行).The climate impacts of flying were on the evening news and the mood changed. Rosen    3     the moment. With her neighbor Lotta Hammar, she launched a campaign called “We stay on the ground”, which has    4    10,000 people to commit to avoid flights in 2019.

Kudos. But here’s the     5     truth: in the grand scheme of things, barely anyone will follow suit. The     6     classes tend to have a lot to say about the eco benefits of avoiding meat, cycling and eating locally sourced food. But that     7     generally disappears when it comes to flying.

We can’t rely on international     8     to stop aviation emission either. Yes, the UN has fixed up a deal to cap aviation emissions beyond 2020. But it lacks real bite, allowing airlines to continue emitting carbon provided they offset (抵消)it.

All this means we could really do with green tech riding to the rescue. Here, at least, there is a little good news. Even rather simple measures like freeing planes to fly in straighter lines could     9     cut carbon emissions. Hybrid (混合动力的)electric aircraft are also the pipeline. And we already know that planes can mix up to 50 per cent biofuels into their tanks and fly safely.

It’s time to redouble our    10     to make planes green. In the meantime, if you are still looking for a New Year’s resolution, you might want to think about joining those 105000 Swedes.
