【題目】Animals, including insects, don't have a "language" like ours. They do not "talk" to each other in words and sentences. But if we watch them, we can see that they do have their ways of communicating with each other.

Can you see the rabbit's tail? When rabbits see this white tail moving up and down, they run away. They know that they are in danger. The rabbit has told them something without making a sound. It has given them a signal.

Many other animals use this kind of "language". When a cobra is angry, it raises its head and makes itself look fierce. This warns other animals. When a bee has found food, it goes back to its home. It cannot "tell" the other bees where the food is by speaking to them, but it does a little dance. This tells the bees where the food is.

Some animals "say" things by making sound. A dog barks, for example, when a stranger comes near. A cat purrs when it is pleased. Some birds make several different sounds, each with its own meaning. Sometimes we human beings speak in the same way. We make sound like "Oh" or "Ah" when we are frightened or pleased or when we drop something on our toes.

1A rabbit uses its tail to ________.

A. warn other rabbits when they are in danger

B. tell other rabbits where food is

C. make itself look fierce

D. help it to run fast

2When a cobra is angry, it ________.

A. makes a loud noise

B. raises its head

C. moves up and down

D. does a little dance

3Several different sounds can be made by a ________.

A. rabbit B. bee C. bird D. fish

4From the passage, we know that ______ use words and sentences to express ideas and thoughts.

A. all living things B. all animals

C. some birds D. human beings

【題目】If we find a bird nest(), we will have a good place of observing(觀察) and knowing about birds.

Birds sit on eggs and take care of their baby birds from April to June. Because the baby birds are too young to leave the nest, mothers often leave and come back to the nest during the time to look for food. So it is good to observe birds. When we observe birds, we’d better hide ourselves in a close place to the nest, and it’s better to use binoculars(雙筒望遠(yuǎn)鏡).

But how to make a bird nest? It’s very easy. If you want to make one, please follow these:

Making a nest: A good nest must be very fine, strong, thick and easy.

a) Each nest must have six boards. Don’t make the boards too slippery.

b) Dig a small hole in the front of the nest as a door. The “door” is from 3cm to 5cm. So the bird can fly in or out easily.

c) Make sure the rainwater doesn’t go into the nest.

d) One piece of the boards should be easy to open.

e) Please don’t forget to color the nest.

1The most important thing in observing birds is to ______.

A. look for a place near the nest

B. climb trees

C. write down notes every day

D. make a bird nest

2When we’re observing birds, we have to hide ourselves to ______.

A. look after them

B. use the binoculars

C. make them do everything as usual

D. catch the birds at last

3We should leave a hole in the front of the nest so that ______.

A. we can clean the nest

B. the birds can fly in or out

C. we can hang it easily

D. it’s easy to make

4What’s the title of this passage?

A. Birds and men

B. Playing with the birds

C. Observing birds and making bird nests

【題目】Do you think of white when someone talks about a polar (北極)bear? In fact, the polar bear does not have white fur. It just appears to be white. Polar bears have a very good sense of smell. It helps them to find food. During summer, polar bears sleep longer, because they are able to find their food more easily at night. Usually, after a meal, polar bears have a short sleep. A polar bear can have 2-3 babies at a time. They live with their mothers until they are about two and a half years old.

However, polar bears will die out soon because of people. There are only 20,000 to 25,000 polar bears in the world. The ones that are left are trying to survive today. The number of polar bears is becoming smaller and smaller because of the loss of sea ice— polar bears mostly inhabit (居住于) the sea ice, not the land ice. This is happening because of global warming (全球氣候變暖), pollution, hunting and so on.

Ordinary people don't care, but great people have the power and want to save tigers, fight for giant pandas and save polar bears. Ordinary people will wait, but great people will find a new world. For me, I will not wait. I will take the bus more often from now on. Join me and save the polar bears, and of course, the tigers, the giant pandas and...

1According to the passage, which of these answers does NOT make sea ice less?

A. Global warming. B. Pollution.

C. Hunting. D. Travelling.

2What does the word "ordinary" mean in Chinese?

A. 勤勞的 B. 聰慧的 C. 普通的 D. 堅(jiān)強(qiáng)的

3What is the main idea of this passage?

A. To show that the number of polar bears is getting smaller.

B. To tell people that polar bears will soon have nowhere to live.

C. To let people know why polar bears are in danger.

D. To talk about polar bears and suggest that people protect animals.

4Where can this passage come from?

A. A magazine about animals.

B. A book about greetings.

C. A poster about working plans.
