21、 Both African elephants and Asian elephants face serious threats to their long-term survival, although the risks vary widely from place to place. Several million African elephants roamed across the continent as recently as the early 20th century, but today only about 350, 000 remain. Asian elephants were less abundant to begin with, reportedly numbering about 200,000 a century ago. There are now fewer Asian elephants left in the wild, maybe close to extinction unless something can be done to save them.
The main threat to elephants is a familiar one for wildlife around the world: loss and destruction of their habitats. Many elephants also face additional dangers, though, including both direct and indirect conflict with people.
On top of occupying and altering elephant habitats, people also commonly plant food crops there. As more farms appear in forests and plains where elephants are accustomed to roaming, their crops often become easy targets for hungry elephants. A herd can destroy a year’s harvest in one night, leading to understandable hostility among farmers, many of whom are living a poor life and have little income to make up the loss. This sometimes leads to certain killings of elephants, interactions that are dangerous for everyone involved. These clashes lead to hundreds of deaths across Asia and Africa every year, both elephant and human.
Many people around the world are committed to preserving these ancient creatures. Elephants are important keystone species shaping and maintaining the ecosystems around them. Since the main threat to elephants is habitat loss, it makes sense to focus our conservation efforts on preserving what’s left of their natural environment. The fate of elephants is also more broadly linked to the human communities around them, since people with enough legal opportunities to support their families might be less likely to depend on hunting for income. And where farmers clash with elephants on the edges of their remaining habitat, conservationists are trying a variety of creative techniques to help both creatures coexist. For example, many small farmers can’t afford fences strong enough to keep out elephants, but some now surround their crops with beehive fences, which take advantage of elephants’ natural fear of bees. As a bonus, the bees also provide fresh local honey.
【1】What can we learn about the situation of elephants?
A．Asian elephants have died out.
B．They are going through a tough period.
C．African elephants are threatened by climate.
D．They were abundant in the early 20th century.

B．Elephants are forbidden to disturb humans.
C．Humans and elephants can make use of each other.
D．Humans and elephants can live in harmony with each other.
22、 A large supply of acorns (橡实) on the ground last winter provided food for chipmunks (花栗鼠) across New England in the northeastern US as spring returned. Acorns and other nuts are a main part of the animals’ diet. They also eat insects, berries, and other kinds of fruit. The substantial food supply kept chipmunks well fed as they got busy reproducing and having families this spring. Now, the growth in the chipmunk population is so noticeable, with people saying the animals are driving them nuts.
Shevenell Webb, a biologist with the Maine Department of Inland Fisheries and Wildlife (MDIFW), said： “While chipmunks are often entertaining, they can be a bother.” The animals dig through the ground, making holes and passageways. This can lead to the destruction of grass, flowers and other plant life. Chipmunks can be “cute” and “fun to watch in the forest” as they move in and out of holes like playful children, “When their mouths aren’t full of nuts, chipmunks make an interesting chip sound,” Webb said.
Steven Parren is a wildlife program official with the Vermont Fish & Wildlife Department. He said he couldn’t grow flowers with chipmunks digging them up. “They don’t even cease,” he said. There were so many acorns in one area that there was no way the animals could have put them all away for winter. In addition to chipmunks, he is also seeing more squirrels, rabbits and mice this year.
Experts note while small animal populations can sometimes explode, they usually return to normal. Chipmunks can be food for other creatures. They are easy targets for owls, snakes and foxes. But even if they survive such attacks, Webb said individual chipmunks usually only live about three years. Many New Englanders remember a similar rise in the area’s squirrel population in 2018. Webb said that increase led to a lot of roadkill. “We’ve never seen anything like that. That was a once — in — a — lifetime event.”
【1】What does the underlined sentence in the first paragraph suggest?
A．Americans start to pick up nuts as food.
B．Chipmunks are making people annoyed.
C．Chipmunks’ favorite food is some kinds of nuts.
D．Many resources are destroyed by chipmunks.
【2】Which of the following best describes chipmunks?
A．Hateful and noisy.
B．Numerous and aggressive.
C．Adorable but troublesome.
D．Amusing but endangered.
【3】What can we infer about the chipmunk population from the last paragraph?
A．It will return to normal soon.
B．There will be a slight increase.
C．It’ll affect other animals’ population.
D．There’s no need to worry too much.
【4】What is the text mainly about?
A．Plentiful food causes considerable chipmunks in the US.
B．Chipmunks have been part of American life.
C．Numbers of various animals have been rising.
D．Time to live in harmony with wild animals comes.
23、Thanks to YouTube, Streaming first caught on in 2005. Today nearly three quarters of American households subscribe to at least one video streaming service. With almost 200 million subscribers worldwide and a billion hours of content viewed each week, Netflix is by far the biggest paid service. No. 2 is Amazon Prime Video. But for every Goliath, there are a hundred Davids. Many smaller streaming services show nothing but sports, classic movies, or Japanese anime.
In the early days of streaming the appeal was the lower cost, and it still is. The average streamer spends $37 a month and subscribes to three streaming platforms, while the average cable ser pays more than $200 per month. Still streaming has become more expensive in recent years. In 2019, Netflix raised the price of its basic service 12. 5 percent to $8.99 a month. A quarter of its subscribers, who protested price increases, said they would cancel their subscriptions. Few did.
A major reason: streaming networks have become home to many of the most popular TV series, including recent Emmy winners. They offer full-length feature films as well, and last year, Netflix received more Oscar nominations than any other media company. In fact, streaming has changed the Oscar competition, at least for this year. Usually only films shown in theaters are considered, but because of the coronavirus, all movies released online in 2020 are qualified for the 2021 Oscar Academy Awards. That shift is especially good news for Disney, which is putting the much anticipated movie Mulan on a new streaming service, Amazon Prime Video. But watching Mulan from your own home will cost $29.99 — on top of the service’s monthly fee of $6.99.
Too much streaming can have its disadvantages, however. There are those who binge-watch, a term Merriam-Webster added in 2017 with the definition “to watch many or all episodes of a TV series on end.” Alejandro Fragoso from New York holds the Guinness World Record: 94 straight hours.
【1】What do the underlined words “Goliath” and “David” in Paragraph 1 refer to?
A．TV viewers.
B．TV programs.
C．Streaming services.
D．Streaming subscribers.
【2】Why did most Netflix subscribers continue their subscriptions?
A．They cannot go without it.
B．They think it is good value for money.
C．Netflix has controlled the market.
D．They think the low cost is a thing of the past.
【3】What does the good news in Paragraph 3 mean to Disney?
A．The movie Mulan will win an Oscar award.
B．The movie Mulan will generate great profits.
C．The movie Mulan can be released on Amazon Prime Video.
D．The movie Mulan can compete for an Oscar.
【4】What do binge-watchers tend to do?
A．They watch TV series continuously.
B．They start a new life.
C．They break world records.
D．They watch TV series aimlessly
