Ⅴ 阅读理解(每小题6分, 共30分)
Wild beavers(河狸)are back! Experts say that the wild beaver families are doing well. The beavers are even boosting wildlife and the environment!
Over ten years ago, a family of beavers turned up in a part of the river Otter, in Devon. No one knew exactly where they came from. It was a big surprise —wild beavers hadn’t lived in England for around 400 years!
In 2015, the government allowed the beavers to stay there as part of a trial(试验). They wanted to see if these animals could be reintroduced to the wild. The trial ends in February. Some scientists from the University of Exeter already say the beavers help the wildlife in the area. One scientist called it “an amazing story”.
A lot of this is because of dams. Beavers build dams along the river. This creates deep pools in the riverbed and slows the water down. Scientists say this is perfect for many different types of plants and animals! Many plants are growing near the beavers. Different types of animals are also becoming more and more in the river. Beavers also help make flooding less, scientists say. The beavers’ dams slow down the speed of the river, especially after heavy rain.
There are, however, some problems. Beavers gnaw (咬、啃) on trees and this can harm them. Their dams can also sometimes create floods (洪水) on people’s land.
Beavers aren’t the only animals that are being reintroduced to the wild! In 2019, red squirrels were brought back to an area of the Scottish Highlands. Further away, the world’s rarest(罕见的) duck, the Madagascar pochard, is making a comeback. It was set free into the wild on the African island in 2019 and is doing well.
Who knows what other animals might be making a comeback
( C )1. Which of the following best explains “boosting” in Paragraph 1
A. building B. spreading
C. helping D. creating
( D )2. Why did the government want a trial first Because they wanted
to .
A. grow more plants along the river
B. build dams for the beavers in the wild
C. introduce the beavers to the wild
D. see if the beavers could be reintroduced to the wild
( A )3. What are the good things about wild beavers living on the river Otter
A. They help plants grow and make flooding less.
B. They bring heavy rain and floods.
C. They gnaw on trees and harm them.
D. Their dams create floods on people’s land.
( C )4. How many kinds of animals are mentioned in the news story which have
been reintroduced to the wild
A. One. B. Two. C. Three. D. Four.
( B )5. How do you think animal lovers feel about the news
A. Embarrassed. B. Pleased.
C. Tired. D. Disappointed.(共40张PPT)
