【推荐1】After weeks of lockdown, the French are more eager than ever to get away from the breathless cities. But the busy traffic will also serve as a reminder of another annual summer trend here. The French have the unfortunate distinction of being the European champions for abandoning pets that have become too cumbersome for their summer trips. Animal shelters up and down the country are evidence of this unique and sad tradition.

Betty Loizeau has run a shelter just north of Toulouse for more than 20 years. “Owners call up to say where their pets can be found, or drop them off in boxes outside the shelter under the cover of darkness. The excuses they typically give are that they’re going on holiday, having a baby, moving house, or they have a new partner with allergies, ...”

For shelters like this one, it is the busiest time of the year. Between 100,000 and 200,000 pets are abandoned in France each year, with 60% of these incidents occurring over the summer. The figure is close to 16,000 in the UK.

“Pets are increasingly seen as an impulsive(冲动的) buy,” says Marina Chailland, a doctor who has studied the social relationship between the French and their pets.

“A certain breed(品种) of cat or dog is fashionable and owners want one, just like a new smartphone,” she says. “Of course, when it goes out of fashion they desert it for an upgrade a couple of years later, when a new breed is considered fashionable.” She also points to the issue of pets being given as gifts as a reason why so many are abandoned. “Often parents will get pets for their children and when they grow up and lose interest in them, out goes the pet.”

Over the summer, owners discover that hotels charge extra for animals or even ban them completely. This explains why you will often see frightened, lost, dogs wandering near freeway service stations or beach resorts.

1. What does the underlined the word “cumbersome” in para. 1 refer to?
A.Disturbing.B.Enjoyable.
C.Disappointing.D.Impressive.
2. Which of the following is true according to the passage?
A.In fact, the French don’t like pets at all.
B.There are various excuses for people abandoning pets.
C.Between 100,000 and 200,000 pets are abandoned in the UK each year.
D.Pets are admitted into the hotel for free in summer.
3. When is the busiest time for a pet shelter in France?
A.In spring.B.In summer.
C.In fall.D.In winter.
4. Why does the author mention the smartphone in paragraph 5?
A.To explain why the French abandon the pets.
B.To explain how the French like a smartphone.
C.To explain why the French dislike pets.
D.To explain how costly a smartphone is in France.

【推荐2】Most polar bears could disappear by the end of the century, scientists say. Global warming is to blame. According to a study published this month in Nature Climate Change, most polar bear populations will be in serious decline by 2080. The cause is melting sea ice.       

Polar bears hunt seals on the ice. Without ice, the bears must wander on the shore, where they are spending more and more time away from their main food source. That means the animals could starve.

“There’s not enough food on land to sustain a polar bear population,” Péter K. Molnár told the New York Times. He is the study’s lead author.

Lack of food leads to another problem: Mother bears may not be fat enough to produce milk for their cubs. Some bear populations could stop having babies, leading to a rapid decline in numbers.

Arctic sea ice usually melts in the spring and summer, then grows in the winter. But now, the ice is taking longer to grow back. Weather statistics say the Arctic is warming twice as fast as the rest of the planet. Ice in the region has declined 13% every 10 years since the 1970s.

The Arctic is home to roughly 25,000 polar bears. Scientists have long known that the animals are in danger. This study, which looked at 13 of the world’s 19 polar bear populations, is the first to identify when they could disappear.

But the study also notes that it is still possible to slow Arctic melting. The world can reduce the burning of fossil fuels and lower the greenhouse gas emissions that contribute to climate change. It would have to be a drastic reduction. Bringing emissions to only a moderate level will still mean the loss of some polar bears.

Saving the bears is up to us, Holland says. “I believe that there is hope,” she says. “But humans need to act quickly to turn that hope into a reality.”

1. Why are polar bears in danger of disappearing?
A.Lack of seals.B.Global warming.
C.Less milk for cubs.D.The loss of home.
2. What does the underlined word “ sustain” in paragraph 3 probably mean?
A.Reduce.B.Suffer.C.Support.D.Increase.
3. What is Holland’s attitude toward saving the polar bears?
A.Doubtful.B.Neutral.C.Negative.D.Positive.

【推荐3】Bees may soon need to add protein shakes to their diet. Pollen (花粉) normally provides their protein (蛋白质). But rising levels of carbon dioxide (CO2) in the air have reduced the protein in pollen. That’s what a new study finds.

Scientists compared recently collected flowers from Canada goldenrod. Then they compared pollen in them to pollen in goldenrod reserved at a museum in Washington, DC. They found today's plants have less protein. Protein levels in pollen from the older flowers were 18 percent. Today's goldenrod pollen has only about 12 percent protein. That's about one-third less than 172 years ago. Over that same period, CO2 levels have gone up by more than one-third. Back more than 170 years ago, they were about 280 parts per million in air. Today they are about 398 ppm.

To test whether CO2 changes had played a role in the falling protein levels, the researchers did some tests. They grew goldenrod for two years at CO2 levels of up to 500 ppm. More CO2 in the air led to lower levels of protein in the flowers’ pollen.

Joan Edwards, one of the researchers, says that this drop in pollen protein could affect a bee’s diet and health. It would be like eating junk food, tasting good but offering less nutrition (营养).

Honeybees need to eat lots of protein. They use it to feed their young. They also need it to keep their immune systems healthy, says Cédric Alaux, a bee biologist at the French agricultural research agency.

Bee populations have been decreasing worldwide in recent years. A drop in their food quality might play a role, Edwards says. And that drop might affect crops too. “The health of the bee population is not just for the flowers and the bees and biodiversity.” She worries it also could play a role in “human health and well-being.”

1. The second paragraph is mainly developed by __________.
A.giving examplesB.following the time order
C.explaining reasonsD.providing numbers
2. According to the text, Joan Edwards might agree that ____________.
A.the drop of protein in pollen has a good influence on bees
B.today’s flowers can provide bees with enough nutrition
C.the drop of protein in pollen leads to a smaller population of bees
D.the smaller population of bees has nothing to do with the human race
3. What is the main idea of the text?
A.Today’s flowers contain more protein.
B.Protein levels in pollen connect with CO2 levels.
C.Drop of protein in pollen affects bees.
D.Bee population is becoming smaller recently.
