1 . 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。

Most polar bears could die out by the end of the century due to global warming,     1     (scientist) say. According to a study, most polar bear populations will be dropping markedly by 2080. The cause is melting (融化) sea ice. Polar bears feed     2     (main) on seals on the ice. Without ice, the bears have to walk to faraway places and spend more and more time away from     3     (they) main food source. That means the animals could die.

Lack of food leads to another problem: Mother bears may not be fat enough to produce milk for their babies. Some bears could stop     4     (have) babies, which results     5     a rapid decline (减少) in numbers.

Arctic sea ice usually melts in spring and summer, and then grows in winter. But now, the ice is taking     6     (long) to grow back. Weather statistics say the Arctic is warming twice as fast as the rest of the planet. Ice in the region     7     (drop) by 13% every 10 years since the 1970s.

But the study also notes that it is still possible     8     (slow) Arctic melting. The world can cut the burning of coal, oil, etc. and lower the greenhouse gas emissions (排放)     9     bring about climate change. It would have to be a big drop to make     10     difference.

2 . The world’s coral reefs do more for the planet than provide underwater beauty. They protect shorelines from the effects of hurricanes. An estimated 500 million people earn their livelihood from the fishing stocks and tourism opportunities reefs provide. The tiny animals that give rise to reefs are even offering hope for new drugs to treat cancer and other diseases.

Despite their importance, warming waters, pollution, ocean acidification, overfishing, and physical destruction are killing coral reefs around the world. So now scientists around the world are looking for all kinds of ways to protect and maybe even revive(复苏) corals. In the Bahamas, Ross Cunning, a research biologist at Chicago’s Shedd Aquarium, is focusing on corals with genes that could make them natural candidates for restoration projects. He recently published a study of two Bahamian reefs, one that seemed to survive an intense 2015 heat wave, and one that didn’t.“It sets the stage to find out which genes are responsible for thermal tolerance,” says Cunning, adding that he hopes discovering those genes will help scientists one day breed more heat-tolerant coral.

In Massachusetts, Cohen’s research has found two key elements that seem to protect corals. The first: internal(内部的) waves beneath the ocean’s surface that bring cooler currents to heat-struck corals, essentially air-conditioning them as temperatures rise. The second: adaptation, a quality that corals found in Palau’s warm lagoons(环礁湖) seem to display.On average, these lagoons submerge(淹没) coral in water that is two degrees Celsius warmer than the water outside the lagoons. “We think the fact that they can deal with these higher temperatures is built into their genetics and allows them to deal with the heat waves.”

She’s also found evidence of corals evolving more quickly in the past two decades to withstand rapidly warming temperatures. The big question scientists are now enquiring into, says Cohen, is whether there’s a cap on how much more heat corals can adapt to. Cohen calls these regions with heat-adapted corals as “super reefs,” and like Friendlander, advocates for using marine reserves to protect them.

3 . You are welcome to our channel. An interest in the way ocean currents move led Dr. Erik van Sebille to track garbage. This Dutch scientist hopes that by making us aware of how much we litter our oceans, we’ll be motivated to better stash (存放) our garbage.

Question: Where does the garbage in our oceans come from ?
Answer: It can come from litter people leave behind on beaches. Or from things falling off ships. Almost every river’s garbage will end up in the ocean too. Plastic garbage is the biggest problem, though. That’s because it doesn’t easily break down. It can stay in the ocean for thousands of years. Eventually, it arrives at the garbage patches (垃圾带).
Question: Does this mean that ocean garbage is worse than garbage on land ?
Answer: Litter in the ocean is probably just as bad as litter in a forest or a park. The main problem in either place is that, if animals eat plastic pieces, they can become very ill. But we know how to solve the problem: Just stop polluting!
Question: Many persons love tossing a message in a bottle into the ocean. Is that a bad idea ?
Answer: Finding a bottle with a message in it is awesome, very special! But most bottles will never end up on a beach. They’ll turn up in the garbage patches, where it’s unlikely that someone will find them. If you want to play with ocean currents, go to the website and release virtual bottles. That way, you’re   not littering our oceans.
1. Animals can become very ill if they _______________.

A．turn up in the garbage patches.	B．arrive at the garbage patches.
C．eat plastic pieces.	D．play with bottles.

2. It is almost _______________ to toss a message in a bottle into the ocean.

A．educative.

B．useful.

C．interesting.

D．meaningless.

3. This passage belongs to a   _______________.

A．story.

B．poem.

C．scientific article.

D．television interview.

4 . New Zealand plans to put a price on sheep and cow burps (打嗝) to reduce greenhouse gas emissions (排放). If the plan is passed, New Zealand will become the first country to tax (征税) farmers on each burp of their cattle, since the burps give out methane (甲烷) into the atmosphere.

“There is no question that we need to cut the amount of methane we are putting into the atmosphere, and an effective emissions pricing system for agriculture will play a key part in how we achieve that,” Climate Change Minister James Shaw said.

Animal agriculture is one of the leading causes of global warming. It is reportedly responsible for at least 14.5% of the world’s emissions. Moreover, cows are by far the biggest contributors. This is so because they produce 40% of global methane when they burp, fart (放屁) and produce waste. Also, methane is 80 times more warming than CO₂ although it’s shorter-lived in the atmosphere.

New Zealand, which has a population of five million people, has around 10 million cattle and 26 million sheep. “Almost half the country’s total greenhouse gas emissions come from agriculture, mainly methane,” the draft plan explained.

The “burp tax” is expected to take effect in 2025. Mr. Shaw wants farming to be more environmentally friendly. He also wants farmers to change the way they farm. He wants them to feed their animals on seaweed instead of grass. This will produce fewer emissions. Mr. Shaw also said farmers can reduce the tax they pay by planting more trees. Another suggestion is for cows to wear special masks.

New Zealand’s farmers support the government. They want to do their bit to help the environment.

1. Why will cattle’s burps be taxed?

A．To raise more money.	B．To feed more cattle.
C．To limit cattle’s price.	D．To better the environment.

2. Which is a fact about New Zealand according to the text?

A．Its cows produce 40% of global methane.

B．Its agriculture affects greenhouse gas emissions.

C．It is responsible for at least 14.5% of the world’s emissions.

D．There is 80 times more methane than CO2.

3. What can farmers do to pay less tax according to Mr. Shaw?

A．Plant more trees.	B．Correct their way to farm.
C．Feed their animals on grass.	D．Wear special masks when farming.

4. Which can be the best title of the text?

A．New Zealand reducing greenhouse gas emissions

B．New Zealand’s greenhouse emissions and animal farming

C．New Zealand introducing a new tax to help the environment

D．New Zealand’s farmers joining in the fight against climate change

5 . 语法填空

The dodo is the most famous of all the creatures     1     (become) extinct in recent history. The remains of the dodo at Oxford are one of the greatest treasures of its museum. 

The dodo     2     (discover) by Europeans in 1507.It was a flightless bird     3     lived on the island of Mauritius in the Indian Ocean. Although the dodos were easy     4     (catch),their meat was not that tasty; their rapid decrease was probably due less to hunting, and more to the fact    5     the dogs, cats, rats and pigs,     6     (introduce) to Mauritius, destroyed the dodos’ eggs and habitat. By 1680 the bird was extinct. 

The dodos were a curiosity, and some were brought to Europe by     7     (wealth) collectors like John Tradescant. His     8     (collect) were later brought to Oxford, where now only the dried head and foot remain. Although small in amount, these specimens (标本) represent the most complete remains of a single dodo, and are     9     great value to scientists today. 

DNA research has shown the dodo is     10     (close) related to pigeons and has finally solved the question of the dodo’s ancestors; without the Oxford specimens this would have been impossible.

6 . One afternoon in 2022, something on the Internet caught my eye：a tiny hedgehog (刺猬) held by a big hand. The post read: “HELP! My hedgehog abandoned (抛弃) her two babies, and I cannot raise both of them because I have to go to school full­time. Good home with experience needed as soon as possible!”

   

I had no experience with baby hedgehogs. I was an animal person through and through and had raised cats, dogs, birds, and guinea pigs. But this tiny animal was new to me, and it touched me that he was abandoned, that maybe I could love him and be the best mom for him.

I wrote the most heartfelt email I could. That was how I found my Louie. True to my word, he was my baby. Louie didn’t know he was a hedgehog. He never curled (蜷缩) into a ball, and he liked my two cats, no fear. The cats, however, were afraid of him, as he often moved into the room, running after the cats and blocking my way.

By the time he reached old age, Louie had only three feet. However, he still managed to climb the stairs to visit other animals. He helped me realize my dream of hedgehog photography, a hobby that began during childhood with cats and dollhouses. I love showing off his modeling.

Life has meaning because of the purpose we have. Louie needed a good home and mom, and in return, I got to be a good mother and be needed. Hedgehogs require great amounts of patience, trust, and knowledge—but the payoff (回报) is pretty great.

1. The author got Louie from           .

A．a pet shop	B．a family friend
C．a hedgehog owner	D．a hedgehog rescue center

2. How did Louie seem to feel at the author’s home?

C．He always refused to be in photos.	D．He was active despite his difficulty in moving.

4. What does the author say about raising Louie?

A．It was easier than expected.	B．It gave her a sense of safety.
C．It made her lose her patience.	D．It was satisfying and meaningful.
