1 . When I take a walk around the park, I often see many people walking with dogs. Perhaps a dog is one of the most useful animals in the world. People keep dogs for different reasons. In the past many people kept dogs mainly for their safety. But now more and more people keep dogs as their friends. For a child, a dog is a friend when he has no other children to play with. For young people, a dog is their friend when they are alone at home. For old people, a dog is their child when their own children grow up and leave home. Now you can see the reasons why people keep dogs.

2 . Dogs are the best pets of humans (人类). They are in all sizes. Some dogs are as small as a football, and others are as tall as a desk. Dogs’ fur is different, too. It can be long and soft, or smooth (光滑的) and hard. People don’t mind the kind of fur, because all dogs are good to hug.
We need to take care of our dogs. Short-haired dogs are the easiest to look after. But all dogs need a bath once in a while. Giving a dog a bath is a lot of fun. After you give a bath to your dog, it shakes the water off its body. Be careful, or you will get wet!
Dogs like to make their owners happy, so dogs are easy to train. They can follow simple orders. Dogs are really wonderful animals. Some dogs pull sleds (雪橇) across icy places. Some save people who fall into the river. Other dogs do tricks (表演绝技) in movies.

Who is the greatest architect（建筑师）in the animal kingdom? The answer is the beaver（河狸）. Beavers are very good at building their homes.
Beavers have large teeth. Their upper incisors（门牙）are about 20 to 25 mm long, according to Live Science. They continue to grow throughout a beaver’s lifetime. To keep their teeth sharp, beavers have to bite and break tree branches, which they also use to build their houses.
Their houses look like domes（圆顶状物）. They usually build their houses in the middle of rivers, with just one underwater entrance. They also use branches, trees and mud to make dams（大坝）. The world’s largest beaver dam is 850 meters long and located at the edge of a lake in northern Alberta. Scientists used a satellite（卫星）to take a picture of it in 2007. They believe several generations（几代）of beavers have been working on this dam since the 1970s.
Beavers’ dams can help to form wetlands, which can create a nice environment for other animals.
They can also purify（净化） water by using their dams to stop some dirt from entering downstream areas.
1. Beaver is the greatest2. Beavers’ teeth continue
3. They have to bite and break tree branches
4. They make dams by using

Humans have many ways to say “hi” and “bye”. It’s a way to be polite. But did you know that apes also do this?
According to a new study, we have found this kind of behavior (行为) in animals for the first time. Many animals greet each other, but they don’t say “goodbye” like apes do.
Scientists studied over 1,200 apes. Of course, they don’t say “What’s up?” like we do. They use body language.
For example, they will touch each other or hold hands. They might also butt (顶) heads or just look at each other. They do these things both before and after they spend time together. These greetings will be shorter if the apes already know each other. Humans do this too.
Scientists say that the common ancestors (祖先) of apes and humans might have done this as well. Then they passed down the habit to both of us.
1. What does the underlined word “this” refer to?| A．Say “hi” and “bye”. | B．Pass down the habits. | C．Study the behavior. |
| A．asking questions | B．giving examples | C．showing steps |
| A．Apes also Greet | B．Apes Are Polite | C．Apes and Humans |
7 . Millions of years ago, dinosaurs (恐龙) controlled the earth. And there were different types of dinosaurs on the earth. Some of them were no bigger than chickens, but all of them had very small brains (大脑). Later on, there weren’t any dinosaurs. What happened to them?
In the days of dinosaurs, the whole earth was warm and wet. There were many green forests. But the earth changed slowly all the time. When parts of the earth became cold and dry, the forests there died. Then dinosaurs could not find enough food to eat. This must be one reason why dinosaurs died out.
What’s another reason? We can make a guess. New kinds of animals came to the earth. Some had big brains and were fast and strong. They could kill dinosaurs. Some ate dinosaur eggs, too.
There may be other reasons that we do not know about. Each year, people will find some dinosaur footprints (脚印) and bones. Scientists are trying to tell us more about dinosaurs.

8 . Plants are very important. This is because plants can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight. Animals can get their food by eating plants and other animals. Man gets his food by eating plants and animals, too. So animals and men need plants in order to live. This is why there are so many plants around us.
There are two kinds of plants: flowering plants and non-flowering plants. Almost all the trees around us are flowering plants. You can know some trees from their flowers and fruit. Non-flowering plants do not grow flowers. You can not see many non-flowering plants around you.
If you look carefully at the plants around you, you will find that there are many kinds of plants. Some plants are large and some are small. Most of them are green. Thanks to the plants around us, we can live on the earth.

10 . National parks are large areas of public land. They give a safe home for local plants and animals. They help keep the air and water clean. They also give us the best trips.
