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.

【推荐1】The Judge Monkey


A long long time ago, there were two cats who lived in the countryside. One day, they were playing along the riverside. Suddenly they saw a loaf of bread lying under a tree. Both jumped upon it and caught the bread at the same time. "It is mine. I saw it first," said one cat. While the other said, "I got it first, so it belongs to me" After having quarreled for some time, one cat said, "Let's divide it into two and take one piece each. ""A good idea, " said the other cat. "But how do we divide it now?

A monkey sitting on the tree watched what happened between the two cats. "That loaf of bread looks good. I could eat it myself" he thought. Slowly he came down from the tree and walked up to the two cats.

"My dear friends! Can I help you?" asked the monkey. The cats told the monkey what the problem was and said, "Why don't you be the judge between us" When the monkey nodded, the cats said, "Please divide this loaf of bread for us."

The clever monkey broke the bread into two pieces. But one piece was a little bigger than the other. "Oh no! I will take a little bite of this bigger piece to make both equal" said the monkey. But he took a big bite. "Uh oh! Now it has become smaller than the other piece. I will just have to take a little bite from that one, too," said the monkey.

The Judge Monkey took another bite. The two cats sat in front of the monkey, seeing the loaf of bread getting smaller and smaller. When the whole loaf was eaten by the monkey, the monkey said, "I am sorry. It was really difficult to divide the bread. I must be going now." And the monkey jumped onto the tree and was gone. "If only we had not quarreled between ourselves, we would have remained united and we don't need to go to the monkey and become hungry now," said the two cats.

文章大意:本文主要介绍教宠物狗懂得“No”。

【推荐2】Every dog should learn the command (命令) “no”. When the dog hears “no”, she should stop doing what she is doing before she hurts (伤害) herself, hurts you or someone else, or breaks things. Sometimes giving the command with body languages (语言) is useful. The command will help your dog learn a little self-control (自控). Here are some things that you can do.

1. Show your dog the behavior

To teach the dog “no”, begin by showing her the behavior (行为) you want her to know. For example, show her a treat in your hand, and then say “no” before closing your fist (拳头) around the treat. Let her smell at your hand, but don’t give her the treat. If she stops trying and turns away, give her a treat from your other hand.

2. Have patience

You can do the exercise ten times or even more before your dog understands that she gets the treat by leaving your closed hand alone. Stay patient enough with her, and always give a good treat if she can do it well.

3. ______________

Your dog will understand you by watching what you are doing. So, watch your body language. Stand tall and give the command in a strong voice, but don’t try to make her angry. You want her to understand and follow the command, not to make her afraid.

4. Teach your dog to follow the command with the treat on the floor

“No” is easier when your dog can’t reach the treat anyway (when it’s in your fist). The next step is to place the treat on the floor with your hand. You may have to start with your hand completely around the treat, but over some times, begin lifting your hand until she stops when you say “no” even with the treat in the open.

1. Which of the following sentences can be put in ________?
A.Talk to your dog gentlyB.Be careful with your body language
C.Make friends with your dogD.Teach your dog to follow you all the time
2. What can we learn from the passage?
A.Dogs always get hurt and can’t control themselves.
B.People like playing tricks on their own pet dogs.
C.It’s very easy to teach a dog to understand her owner.
D.Giving dogs a treat is very important when teaching “no”.
3. What is the passage mainly about?
A.Teaching pet dogs to understand “no”.B.Showing the ways to live with dogs.
C.Stopping dogs hurting people around them.D.Showing the love between animals and people.
