1 . Does your family buy the week’s groceries including many bottled drinks into your home? Because after having sports or hanging out under the sun, it’s so cool to get a cold one right out of the fridge, right?

But all those plastic bottles use a lot of oil and pollute the environment. Americans buy more bottled water than any other nation in the world with 29 billion water bottles a year. In order to make all these bottles, 17 million barrels (桶) of oil will be used up. That is enough oil to keep a million cars going for twelve months.

Most people choose to throw the bottles away after having the bottled drinks. In fact, instead of going out with the trash, plastic bottles can be turned into carpeting or clothing. Remember this: Recycling one plastic bottle can save enough energy to power a 60-watt (瓦特) light bulb for six hours.

Unfortunately, for every six water bottles we use, only one is made recycling. The rest are sent as garbage. Or, even worse, they end up as trash on the land or in rivers, oceans. Plastic bottles take many hundreds of years to disintegrate (分解).

So why don’t more people drink water from the kitchen? Some people drink bottled water because they think it is better for them, but that’s not true. The chemicals in the bottles themselves may get into the water which can do harm to people.

So next time when you have drinks or water, please try to use a glass at home or carry water in a steel bottle. And if you want to do something more, try to collect plastic bottles and send them for recycling.

3 . The good news is that more people bought electric vehicles （EVs） in 2020. The bad news is that sport utility （多用途的）vehicles （SUVs） continued to grow in popularity, too. “The fall in oil consumption due to the first trend was completely canceled out by the second," said Laura Cozzi, an officer at the International Energy Agency （JEA）,

Between 2010 and 2020, global carbon dioxide emissions （排放）from conventional cars fell by nearly 35 billion Lons, due to reasons such as fuel efficiency improvements as well as the switch to electric cars. Emissions from SUVs rose by more than 50 billion tons. "While the growth in EVs is encouraging, the boom in SUVs is heart-breaking," says Peters at the Cicero Climate Research Centre in Norway.

There are many reasons for the growing popularity of SUVs. For example, rising economic boom in many countries means more people are able to afford them. Some people see them as status symbols. Also, SUVs are heavily advertised by car-makers, whose profit is higher on these vehicles. Some countries, including France, have introduced plans under which more taxes are paid on heavier cars. But Peters thinks that people who are rich enough to afford SUVs won't be deterred by slightly higher taxes. "There are now some electric SUVs available, but 1 hope one day you will see more electric vehicles brought to the SUV market," says Peters.

Even if it happens, switching to electric SUVs isn't a good solution. Due to their size and bigger batteries, it takes more resources to build electric SUVs, and they consume around 15 percent more electricity. That means higher emissions unless the electricity comes entirely from renewable sources, and higher electricity demand makes it harder to green the electricity supply.

1. What can we infer from Paragraph 2?

A．Scientists should devote themselves to improving fuel efficiency.

B．The emission of carbon dioxide of motor vehicles has hit a new low.

C．Electric vehicles will certainly take the place of sport utility vehicles.

D．The popularity of SUVs destroys some efforts at environmental protection.

2. What does the underlined word "deterred” probably mean?

A．Blocked.

B．Encouraged.

C．Removed.

D．Involved.

3. What is one of the reasons that SUVs are popular with consumers?

A．SUVs are discounted heavily.

B．SUVs are often advertised by car producers.

C．SUVs are taxed at a lower rate in some countries.

D．SUVs consume fewer resources than other vehicles.

4. What point does the author try to make in the last paragraph?

A．The electric SUVs should be made smaller and lighter.

B．The electric SUVs are a good guarantee for less pollution.

C．More electric SUVs don’t necessarily mean "environment-friendly".

D．Future electric SUVs will be powered with completely green energy.

4 . Ever since Earth formed roughly 4.5 billion years ago, its climate has gone through a number of incredible changes.

All you have to do is look at images of the Jurassic Period (侏罗纪时期) to know that at one time, much of our planet was covered in extremely hot and humid jungle. Skip ahead a couple million years and you get to an ice age event, when global temperature experienced a huge drop. While many species were not able to deal with these changing climate patterns, others successfully adapted, and some are even still with us today. Now, as humanity pushes the planet closer to another extreme climate event, scientists are eager to find out how the world's species will react. The idea was highlighted in a study published on April 6 in the journal PNAS, which showed that between 1970 and 2010, open water species such as lobsters and fish had declined by about half in tropical marine zones across the globe because over the 40-year time period, sea temperatures in those regions had risen by roughly 0. 2°C.

The lower numbers aren't a sign of all the sea creatures dying off though. In fact, the scientists found some of them outside of their traditional habitats, meaning that if a species can migrate to cooler waters and adapt in a new environment, they will.

However, those movements aren’t always a good thing; species that can' t move, such as coral, which is fixed to the seabed, rely on the fish and other sea creatures to contribute to the natural food chain and stay healthy. Additionally, when a non- native species moves into a new area, it threatens to disrupt the ecosystem that already exists there.

Depending on the species, it can take anywhere from one generation to thousands and thousands of years to properly adapt, so the changes that have occurred in just the last 40 years are very troubling for scientists. As Sebastian Ferse, an ecologist at the Leibniz Centre for Tropical Marine Research, Germany, explained, “In geological history, this has occurred in the blink of an eye. To see such changes occurring so rapidly is something quite alarming.

1. What can we infer from Paragraph 2?

A．Some species that adapted to the climate changes survived.

B．Most species were able to deal with the changing climate patterns.

C．Global temperature experienced a huge drop during Jurassic Period.

D．Much of our planet was covered in humid jungle during ice age event.

2. How did some sea creatures survived climate changes according to the scientists?

A．By changing their food chain.	B．By adjusting their own temperature.
C．By moving to other places and adapted.	D．By human beings' protecting.

3. What does the underlined word “disrupt” in Paragraph 4 mean?

A．Improve.

B．Balance.

C．Disturb.

D．Establish.

4. Which word best describes scientists' attitudes to the migration of species?

A．Optimistic. .

B．Negative.

C．Objective.

D．Indifferent.

5 . When it comes to the beaches in Sydney, it's hard to know where to begin. Around 100 beaches spread around the harbor and along the coast. Here are four of them.

Bronte Beach

Bronte's sea pool offers a protected ocean swim and is regarded as one of the best in Sydney—and much like beach culture itself, it's free. The nearby parkland has spacious barbecue areas for family gatherings. On public holidays, the park becomes a sea of busy people as parties take place.

Balmoral

Balmoral, on the north shore's Middle Harbor near Taronga Zoo, has an air of peace. Life moves at a more leisurely pace here. If it's loudness and pride you're after, this isn't it. What Balmoral does have overall is impressive views. And its calmness makes it a great swimming spot for families.

Garie Beach

Located in the Royal National Park, 54 kilometers south of Sydney, Garie Beach is accessible through Garie Road and isn't one for beach-lovers without a car. The large beach is very impressive, though. It's well preserved and is the perfect spot for a relaxing day away from the city. The facilities are top-grade and there is a great fishing spot off the east-facing rocks.

North Narrabeen Beach

Having some of the best and most consistent surf, the beach attracts board lovers from all over Sydney. Surfers have no discomfort making the 25-kilometer trip north to get to the three-kilometer-long beach. The northern end of the vast beach is protected from the northeasterly winds and is a surfer's destination, while the rest of it is ideal for swimming.

1. What do Bronte Beach and Balmoral have in common?

A．They are both family-friendly

The Xi’an City Wall is the most complete city wall that has survived China’s long history. It     1     (build) originally to protect the city     2     the Tang dynasty and has now been completely restored (修复). It is possible       3     (walk) or bike the entire 14 kilometers.

We accessed the wall through the South Gate. The wall is 12 meters high and from here you can see streams of people moving inside and outside the City Wall.

After     4     (spend) some time looking at all the defensive equipment at the wall, we decided it was time for some action and what     5     (good) than to ride on a piece of history!

We     6     (hire) our bikes from the rental place at the South Gate. My bike was old and shaky     7     did the job. It took us about 3 hours to go all     8     way around the Xi’an City Wall.

9 . 阅读下面短文，在空白处填入1个适当的单词或括号内单词的正确形式。

Ecotourism is commonly regarded as low impact (影响) travel to undisturbed places. It is different from traditional tourism because it allows the traveler to become     1     (educate) about the areas - both in terms of geographical conditions and cultural characteristics, and often provides money for conservation and benefits the     2    (develop) of the local areas.

Ecotourism has     3    (it) origin with the environmental movement of the 1970s. It was not widely accepted as a travel concept     4     the late 1980s. During that time, increasing environmental awareness made it desirable.

Due to     5     growing popularity of environmentally-related and adventure travel, various types     6     trips are now being classified as ecotourism. Actually, a true eco-friendly trip must meet the following principles:

·Minimize the impact of     7    (visit) the place.

·Build respect for and awareness of the environment and cultural practices.

·Provide     8    (finance) aid and other benefits for local peoples.

·Make sure that the tourism provides experiences for both the visitors and the hosts.

Komodo National Park, officially recognized in 1980, is popular for ecotourism because of its unique biodiversity.    9    (activity) there range from whale watching to hiking (远足) and accommodations aim     10    (have) a low impact on the natural environment.

10 . Pre-school children who spend time together take on one another's personalities, a new research has found. The study shows that environment plays a key role in shaping people's personalities. While genetics still forms the central part of the human psyche (心理), the research finds that personality traits (特征) are "contagious" (传染的) among children. "Our finding flies in the face of common assumptions that personality can't be changed," said Dr. Jennifer Neal, co-author of the study.

The researchers studied the personalities and social networks of two pre-school classes for a full school year. One of the classes was a set of three-year-olds, and the other a set of four-year-olds. Children whose friends were hard-working or outgoing gradually took on these personality traits over time. Psychology expert Dr. Emily Dublin said kids are having a far bigger effect on each other than people may realize.

The new study is not the first to explore the contagious effects of personality traits. A 2015 psychology study found that rudeness at work can be contagious as it travels from person to person "like a disease". The study found that seeing a boss being rude to an employee was enough to cause people to be rude to those around them.

The researchers questioned 6,000 people on the social "climate" in their workplaces, which included offices, hotels and restaurants. They found 75 percent of those who took part said they had been treated rudely at least once in the past year. And the study also suggests that merely seeing other people being subjected to rudeness made it more likely that a person would treat their colleagues in the same way. Rudeness could include leaving someone off an invite to a company event, sending unkind emails, finding fault with others or failing to give praise.

Dr. Torkelson believes companies need to be more aware of the harm that rudeness in the workplace can do as it can damage the working environment. She said better training could help to fight against the problem.
