About 20,000 years ago,much of Europe,Asia,North and South America was covered by huge sheets (片) of ice,each many kilometres thick.Since then,the ice has gradually melted and the ice sheets have retreated.Today,the only ice sheets on Earth’s land masses are found in Antarctica and Greenland.Some ice also occurs as glaciers in mountainous regions and as floating ice floes (浮冰块) in the Arctic Ocean and around Antarctica.

At first sight,these remote left-overs from the last Ice Age seem of little importance for most of us today.However,nothing could be further from the truth.Many scientists believe that our planet is warming as a result of the greenhouse gases that we are pumping into the atmosphere.If the planet becomes warmer,the ice sheets will start to melt,causing sea level to rise perhaps several metres by the end of this century.Such a rise would cause widespread flooding of low-lying coastal areas and threaten many large cities.

Observations from space suggest that parts of the major ice sheets are beginning to melt more rapidly.Meanwhile,recent satellite images have also shown that unusually large areas of sea ice have been melting during the Arctic summer.Although sea level will not be affected by the melting of the floating ice,there will be other important environmental changes.For example,ice sheets act like a mirror,reflecting sunlight and cooling Earth.If the ice disappears,Earth is likely to become warmer and major climate changes could occur.Wildlife living in the polar regions may also be destroyed.

1. What does the underlined word “retreated” in Paragraph 1 probably mean?
A.Grown.B.Reduced.
C.Formed.D.Disappeared.
2. What’s most common people’s attitude towards the ice sheets?
A.Optimistic.B.Critical.
C.Sincere.D.Unconcerned.
3. What would happen if the greenhouse gases continue to increase?
A.Vast amounts of land will be flooded.
B.Large cities in the world will disappear.
C.The sea level will drop to its lowest level.
D.Global temperatures will see ups and downs.
4. What can we infer from the last paragraph?
A.Ice sheets melt faster than floating ice.
B.The melting of floating ice isn’t damaging.
C.Sea ice melting will have disastrous effects.
D.Space research contributes to climate changes.

文章大意:这是一篇记叙文。文章主要讲述了菲律宾Binan市人们收集火山灰进行循环利用,把火山灰变成建筑材料,变废为宝的故事。

【推荐1】The area around Taal Lake on Luzon Island in the Philippines is known for its natural beauty. Tourism is popular there as travelers go there to see the scenery that surrounds Taal Volcano, one of the most active volcanoes in the country. It was quiet for years until January 12,2020 when the volcano erupted. Since then, the cities surrounding the volcano have been covered with ash and many people are forced to leave home.

But the ash didn’t stop the residents of Binan, a city that is 35 km south of Manilla, from finding a way to help their neighbors in the towns that suffered the most from Taal. Binan Mayor Walfredo Dimaguila ordered the city residents to collect the ash and to put it in sacks (麻袋) to be sent to the state-owned factory that can produce 5,000 bricks (砖) a day to turn it into bricks to use for rebuilding damaged communities.

“What we plan is to turn them into hollow blocks and bricks and sell them to interested companies,” Dimaguila said. But he noted, the money would be donated to the people directly affected by the volcano. “When Batangas (the region where Taal is located) is in recovery, the bricks can not only be used to build schools, community halls and livelihood centers but also help deal with ash pollution for the earth,” Dimaguila said. “The misfortune of our neighbors in Batangas is there. Let’s transform this into opportunity.”

The Philippines, located in the Pacific “Ring of Fire: zone of fire” and part of the typhoon belt, is a country that is known for natural disasters like earthquakes, volcanic eruptions, and major storms. But the Filipino people show their strong will and community spirit.

1. What can be learned about Taal Volcano?
A.It attracts more and more settlers.B.It becomes inactive.
C.It is covered with ash completely.D.It causes damage to the locals.
2. What are people advised to do according to Walfredo Dimaguila?
A.To collect volcanic ash for recycling.B.To save sacks for factories to use.
C.To set up a factory for making bricks.D.To build communities for people from disasters.
3. Which can best describe Dimaguila’s plan?
A.Creative but expensive.B.Environmentally and economically.
C.Helpful but challenging.D.Interesting and practical.
4. What’s the main idea of the passage?
A.Taal Lake is in danger.B.Taal Volcano is popular.
C.Disasters hits Philippines.D.People turn ash into treasure.

文章大意:这是一篇说明文,文章主要讲述一个科学家小组的成员Goodman博士通过厚厚的贝壳层发现了摧毁凯撒利亚港口的巨浪存在的证据。

【推荐2】Two thousand years ago, the ancient Roman city of Caesarea had the largest harbor on the eastern coast of the Mediterranean Sea. It was a wonder of engineering for its time. Then disaster struck. Written records say a huge wave destroyed the harbor. What kind of wave caused it? Did it ally happen? No one had ever found the evidence of the wave... until now.

Dr Goodman is part of a team of scientists studying samples at Caesarea to figure out what happened in the past. A sample is taken by striking a tube into the seafloor. When the tube is pulled up, it contains sediments (沉淀物) that have collected on the seafloor for hundreds or thousands of years. Looking down through the mixture of sand, stones and other sediments is like looking back in time.

That’s what Dr. Goodman was doing when she found something astonishing. It was a layer (层) of shells — all came from the time the harbor was destroyed. Dr. Goodman knew this shell layer had a story to tell.

Usually, shells are part of the mixture of sediments collected on the seafloor. A shell layer is as thin as your finger. Yet Dr. Goodman was staring at a layer nearly 1 meter thick! Almost all the shells were broken.

The thick layer of broken shells meant a sudden, powerful event swept these shells into the area. The broken shells were evidence that a huge wave really did destroy the harbor. Dr. Goodman could even tell the direction of the wave from the way the shells lined up.

Here’s what Dr. Goodman thinks happened. First, an earthquake struck north of Caesarea along the coast. Energy from the movement of rock during the earthquake caused a tsunami. This huge wave raced across the sand and kicked up shells along the way and broke them into pieces. Finally, the wave crashed into the harbor and destroyed it.

Dr. Goodman plans to gather evidence for other ancient tsunamis along the Mediterranean coast. This will help her predict what areas are likely to be struck by future tsunamis. Then people can avoid building in these areas.

1. What can be learned about the Caesarea harbor?
A.It was the largest in the world.
B.It was destroyed by a tsunami.
C.It is a mystery whether it existed.
D.It is studied by many engineers now.
2. How did Dr. Goodman obtain the sample at Caesarea?
A.By studying underwater.B.By analyzing the mixture.
C.By digging for ancient shells.D.By collecting sediments in a tube.
3. Which is the evidence to solve the historical mystery?
A.The direction of the wave.B.The diversity of sediments.
C.The way the shells lined up.D.The thick layer of broken shells.
4. Which can be the best title of the passage?
A.Shells Tell the StoryB.Scientists Predict Disasters
C.Underwater Clues for FutureD.Sea Exploration of Mediterranean

文章大意:本文为一篇记叙文。文章讲述了作者在新奥尔良的家因卡特里娜飓风过境而成为废墟之后,得到了多位陌生人的帮助,尤其是寻找新居的过程中,这些善意让他重新对人性充满信心。

【推荐3】A month after Hurricane Katrina, I returned home in New Orleans. There lay my house, reduced to waist high ruins, smelly and dirty.

Before the trip, I’d had my car fixed. When the office employee of the garage was writing up the bill, she noticed my Louisiana license plate. “You from New Orleans?” she asked. I said I was. “No charge,” she said, and firmly shook her head when I reached for my wallet. The next day I went for a haircut, and the same thing happened.

As my wife was studying in Florida, we decided to move there and tried to find a rental house that we could afford while also paying off a mortgage (抵押贷款) on our ruined house. We looked at many places, but none was satisfactory. We’d begun to accept that we’d have to live in extremely reduced circumstances for a while, when I got a very curious e-mail from a James Kennedy in California. He’d read some pieces I’d written about our sufferings for Slate, the online magazine, and wanted to give us (“no conditions attached”) a new house across the lake from New Orleans.

It sounded too good to be true, but I replied, thanking him for his exceptional generosity, that we had no plans to go back. Then a poet at the University of Florida offered to let his house to me while he went to England on his one-year paid leave. The rent was rather reasonable. I mentioned the poet’s offer to James Kennedy, and the next day he sent a check covering our entire rent for eight months.

Throughout this painful experience, the kindness of strangers has done much to bring back my faith in humanity. It’s almost worth losing your worldly possessions to be reminded that people are really nice when given half a chance.

1. The garage employee’s attitude towards the author was that of        .
A.unconcernB.sympathy
C.doubtD.tolerance
2. What do we know about James Kennedy?
A.He was a writer of an online magazine.
B.He was a poet at the University of Florida.
C.He offered the author a new house free of charge.
D.He learned about the author’s sufferings via e-mail.
3. It can be inferred from the text that       .
A.the author’s family was in financial difficulty
B.rents were comparatively reasonable despite the disaster
C.houses were difficult to find in the hurricane-stricken area
D.the mortgage on the ruined house was paid off by the bank
