Question

【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.

【1】If the fruit is moved to a new position, the ants will ________.

A.fail to find itB.give up looking for it

C.make a new direct route to itD.get to it through the old trail route

【2】Which is the correct order to do this experiment?

a. Move the fruit to a new position.

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?

A.The experiment is done successfully in the lab.

B.Ants do the experiment to show their team spirit.

C.Careful watching does little help in this experiment.

D.We can find out some facts by doing small experiments.

Answer 1

【答案】

【1】D

【2】B

【3】D

【解析】

文章大意：本文通过实验介绍了蚂蚁的团队合作。

【1】细节理解题。根据文中的信息But, instead of making a new direct route to the food, they will follow each other through their old trail route. 但是，它们不会选择一条新的直接路线去寻找食物，它们会沿着原来的路线互相追踪。由此可知，如果果实被移动到一个新的位置，蚂蚁将通过旧的路径到达它，故答案选D。

【2】细节理解题。根据文中的表格第一列First，youneedsomeants；第二列Putathinsliceoffruitinfrontoftheant；第三列Checkthefruitanhourlater；第四列Movethefruittoanewposition；可知B的顺序正确，故答案选B。

【3】主旨大意题。根据文中的信息You can see one of the best examples of insect teamwork by watching ants. 可知通过观察蚂蚁的实验可以了解昆虫是如何进行团队合作的，故答案选D。
