【题目】 Here is an experiment (实验) to see how ants can organize some clever teamwork.

What’s going on?

You can see one of the best examples of insect teamwork by watching ants. If one ant finds food, it leads others there to eat it too. They follow each other by making long trails(踪迹). The ants go back and forth collecting food, to take back to their nest（穴）. When you move the fruit, the ants will still find it. But, instead of making a new direct route to the food, they will follow each other through their old trail route.

b. Find an ant.

c. Check the fruit an hour later.

d. Put a thin slice of fruit in front of the ant.

A.a-b-c-dB.b-d-c-aC.d-b-c-aD.c-a-d-b

【3】What can we learn from this experiment?

【题目】 For a long time, scientists believed that only humans were left-or right-handed. However, recent studies have shown that this isn’t true. Just like people, animals favor one side or the other.

In Ireland, scientists studied a group of 42 cats. They gave them three tasks. One was to get a delicious piece of fish out of a bottle. They found that the male cats preferred to use their left paw, and the female cats preferred to use their rights.

Being left-or right-handed isn't limited (有限的) to arms and legs. It can include eyes, ears, claws, and even tails. In Italy, scientists discovered that dogs wag their tails to the right when they see something that they like. When they see something that they don’t like, their tails go to the left.

There are lots of fun examples. Left-handed dolphins swim in a different direction around the pool. Elephants like to swing their trunks in one direction. Even snakes prefer to curl up only one way.

Many people believe that polar bears are left-handed. They say, for example, that polar bears cover their black nose with their right paw, which helps them hide in the snow when they are hunting. Then they can sneak up(慢慢靠近) on a seal, and their left paw will be free to catch it.

Scientists, however, disagree. Some have watched polar bears for thousands of hours. They never saw the bears cover their nose during a hunt. They also saw no evidence(根据) that they were left-handed. Without taking any notice of this, many websites continue to say that polar bears are left-handed.

Scientists are still learning about animals and their behaviors. The next time you see an animal, whether it’s your pet cat or an elephant, try figuring out yourself which it prefers - left or right.

【1】The underlined word"favor"in paragraph 1 is closest in meaning to .

A.giveB.findC.seeD.prefer

【2】In paragraph 2, we can get the information about .

A.an Irish scientist who studies catsB.a study about cats and its findings

C.three tasks done by male and female catsD.an introduction on how cats get fish

【3】Which one of the following statements is true about polar bears?

A.It's believed that polar bears are left-handed for they use their left paw to cover their nose.

B.The findings that polar bears cover their nose while hunting is supported by scientists.

C.Scientists disagree with the popular belief that polar bears are left-handed.

D.The information from many websites that polar bears are left handed is believable.

【4】The purpose of this passage is mainly to .

A.introduce recent studies of animalsB.explain why some animals are left-handed

C.tell us which side animals preferD.learn about animals in different countries

【题目】A:You've tried on two skirts.
