Question

【題目】 We see many animals every day, but we would be worried if we saw any of these animals on our way to school!

Walking sharks

In 2006, scientists found a new kind of shark off the coast of Indonesia. It can “walk” with its fins along the coral reefs. These walking sharks are about 1 to 1. 2 metres long. They eat shrimp, crabs and small fish. If they are surprised by something, they can swim away using their fins.

The platypus

The platypus is found along the rivers and lakes of eastern Australia. It lays eggs like a bird, has webbed feet like a frog, a bill like a duck and is as poisonous as a snake! We are pleased to hear that it spends much of its life underground.

An unusual dolphin

In 2006, a Japanese fisherman caught an unusual dolphin. It has an extra set of fins near its tail, about the size of human hands. Scientists say that its extra fins could be the remains of back legs. This may be proof that dolphins once lived on land. Evidence from fossils tells us that dolphins were once four-footed land animals. Scientists believe that as they spent more and mor time in the water, their back legs slowly disappeared.

【答案】

【1】D

【2】B

【3】C

【解析】

文章主要介紹幾種特殊的動(dòng)物：游動(dòng)的鯊魚、鴨嘴獸、不尋常的海豚。

【1】細(xì)節(jié)理解題。根據(jù)“In 2006, scientists found a new kind of shark off the coast of Indonesia. It can “walk” with its fins along the coral reefs.”可知，在2006年，科學(xué)家發(fā)現(xiàn)一種新的鯊魚，它可以用鰭在珊瑚礁上“行走”。故選D。

【2】細(xì)節(jié)理解題。根據(jù)“The platypus中…and is as poisonous as a snake!（像蛇一樣有毒）”可知，鴨嘴獸是有毒的。故選B。

【3】推理判斷題。通讀最后一段，選項(xiàng)A意思是“它能用鰭走路”，文章未提到，故A不正確；根據(jù)“Evidence from fossils tells us that dolphins were once four-footed land animals. Scientists believe that as they spent more and more time in the water, their back legs slowly disappeared.”可知，海豚曾經(jīng)是四足陸生動(dòng)物，隨著它們?cè)谒�中度過(guò)越來(lái)越多的時(shí)間，它們的后腿慢慢消失了，由此說(shuō)明這只不尋常的海豚沒(méi)有四只腳了，故B不正確；根據(jù)“It has an extra set of fins near its tail, about the size of human hands.”可知，它的尾巴附近有一組額外的鰭，故C正確，D不正確。故選C。
