Question

【題目】Next time you need directions,maybe you can ask an ant.These little creatures are masters of navigation（導(dǎo)航）that some can find their way home whether they're walking forward or backward,according to a study in Current Biology.

Ants often travel long to bring back the food to their nests.But how do they know where they’re going?

Researchers went to Spain to mess with some desert ants.They found an active nest and surrounded it with barriers that forced the foraging（搜尋）ants to follow a particular path back home.Once the ants were familiar with the maze,the researchers would take them up,hand them pieces of a cookie and then put them back in a different location,one that required taking a 90 degree turn to get to the nest.

The research found that the ants carrying a small,easy-to-carry piece would run forward with confidence and were able to head on home.Some ants,however,would drop the cookie and turn around to take a look at the scenery, which allowed the six-legged experts to reset their inner maps,catch their cookies and head in the right direction.

These ants seem to use sky clues,like the position of the sun,to keep them on track.When the researchers used a mirror to make it look like the sun on the other side of the sky,the cornered ants would turn tail for the opposite direction.

So ants integrate（整合）a lot of information to successfully bring home the food.

【1】What does the word “maze” in Paragraph 3 probably refer to?

A. A nest that active ants live in.

B. An experiment that is done in the desert.

C. A method that helps to locate food.

D. A place that consists of confusing paths.

【2】Why did some ants stop to look at the scenery?

A. To get over the man-made barriers.

B. To enjoy the scenery along the route.

C. To ensure they're in the right direction.

D. To check directions with their maps.

【3】According to the passage,what probably helps the ants find their way home?

A. The position of the sun. B. One particular path.

C. A 90 degree turn. D. Pieces of a cookie.

【4】Where does this passage probably come from?

A. An adventure novel. B. A geography textbook.

C. A science magazine. D. A tourist brochure.

【4】C

【解析】本文為介紹說(shuō)明文。文章介紹了對(duì)螞蟻為什么能夠準(zhǔn)確找到回家之路的科學(xué)研究。

【1】詞義猜測(cè)題。根據(jù)第三段中的They found an active nest and surrounded it with barriers that forced the foraging（搜尋）ants to follow a particular path back home.（他們發(fā)現(xiàn)了一個(gè)活動(dòng)的巢穴，并在四周?chē)�上了障礙，迫使覓食的螞蟻沿著特定的回家的路走）可推知，maze意指“有令人困惑路徑的地方”。故選D。

【2】推理判斷題。根據(jù)倒數(shù)第三段中的Some ants,however,would drop the cookie and turn around to take a look at the scenery, which allowed the six-legged experts to reset their inner maps可推知，一些螞蟻停下來(lái)四處看看，是為了重置它們的內(nèi)部地圖，找準(zhǔn)正確的方向。故選C。.

【3】推理判斷題。根據(jù)倒數(shù)第二段中對(duì)螞蟻是否在利用空中太陽(yáng)的方位的實(shí)驗(yàn)可推知，螞蟻確實(shí)在利用太陽(yáng)的方位幫助它們找到回家的路。故選A。

【4】文章出處題。文章介紹了對(duì)螞蟻為什么能夠準(zhǔn)確找到回家之路的科學(xué)研究，本文應(yīng)該出自于科學(xué)雜志。故選C。
