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?

【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.

【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. |
A.Talk to your dog gently | B.Be careful with your body language |
C.Make friends with your dog | D.Teach your dog to follow you all the time |
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”. |
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. |
Many kinds of birds live in the United States, but the number of the birds is becoming smaller and smaller every year. One of the leading reasons is the growing number of pet cats. By keeping your pet cats in your home, you can help give birds a better possible chance to live.
Of the 90 million pet cats in this country, about two-thirds are allowed to go outside. It is said that these cats kill hundreds of millions of birds each year as well as billions of small animals such as rabbits and field mice.
They can also bring illness to the animals that live in people’s yard, and further weaken(变弱) the health of the natural populations.
Allowing pet cats to go outside is not just bad for birds and wildlife(野生动物). It is bad for the cats themselves, too. Outdoor cats can get sick very easily. They may be in danger from traffic and attacks(攻击)from other animals. In fact, outdoor cats usually don’t pass the age of five, while indoor cats often live to be 17 or older.
Keep your pet cat inside! If you raise a young cat, it’s your duty to let it play inside.
A.You should let your cat inside. |
B.Going outside is bad for cats, too. |
C.Keeping a cat is good for you. |
D.The birds are fewer and fewer in America. |
E.Cats can bring illness. |
F.Cats kill many birds and small animals every year. |
【推荐1】Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are often believed to be the cause of a number of things from poor eyesight and headaches to house fires. There’s even one theory(理论) that mobile phones should be responsible for the disappearance of bees!
The theory is that the radiation(辐射) given off by mobile phones does great harm to bees’ navigation systems(导航系统). Bees have a built-in system a bit like BDS and this helps them find their way back to their hives(蜂巢). But recently, thousands of bees have failed to find their way home. It is believed they are dying far from their hives.
The problem was first noticed by beekeepers in America and is a lot more serious than it seemed at first. The important thing about bees is that most of the crops in many countries are pollinated by them. Without bees, crops can’t continue to grow.
Nobody knows for sure whether the theory is true or not, but it’s a fact that bees are disappearing in very large numbers. And we can’t manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! If the mobile phone theory is correct, we need to do something about it right now before it’s too late.
1. What might be caused by mobiles according to Paragraph 1?A.Poor listening. | B.Forest fires. |
C.The disappearance of bees. | D.Terrible toothaches. |
A.Bees have BDS inside their bodies. | B.Mobiles have an influence on bees’ hives. |
C.The radiation makes bees unable to fly. | D.The radiation makes bees lose their way home. |
A.授粉 | B.污染 | C.啃食 | D.催熟 |
A.call on people to help beekeepers | B.show how a bee’s built-in system works |
C.ask people to stop using mobiles right away | D.warn people of the possible harm mobiles do to bees |

【推荐3】Everyone doesn’t want to be sick in the vacation. So what can you do while travelling? There are three things you should remember.
A vacation is a time for relaxing, but very often it is not. There are so many places to visit: shops, parks, churches and temples. You may spend most of the days walking around these places.

【推荐1】Americans will long remember President Abraham Lincoln, the 16th President of the UnitedStates.
At the age of 19, Abraham Lincoln took a boat down the Ohio River to New Orleans. There Lincoln saw for the first time slaves being sold in the marketplace. At that time, Lincoln made up his mind to work to end slavery for the rest of his life.
In 1836, Lincoln became a lawyer and was famous for being hard—working and honest. He believed that the US stood for freedom for all. He wanted to become a senator(参议员). In 1858, Lincoln debated(争论) against Stephen Douglas who was also a candidate for the Senate from Illinois.
Because of the Lincoln—Douglas debates, Lincoln became known across the country. Then he decided to run for the presidency in 1860. At last he ran against Stephen Douglas and two other candidates.
Lincoln took the oath(誓言) of office to become president of the United States on March 4, 1861. It was a difficult time to be president. Many southern states did not agree with Lincoln about canceling slavery, and declared(宣布) that they were no longer part of the US. The famous Civil War began in April, 1861.
Lincoln’s Union Army fought the Southern Confederate Armies. Many soldiers were killed in the battles. One of the battles took place in Gettysburg, Pennsylvania. In 1863, a ceremony was held to memorize the dead on the Gettysburg battlefield. Lincoln made a famous speech known as the Gettysburg Address.
Unfortunately, Lincoln was shot while watching a play at Ford’s Theatre and passed away on the morning of April 15, 1865.
