题目内容

【题目】 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.

【解析】

文章主要介绍几种特殊的动物:游动的鲨鱼、鸭嘴兽、不寻常的海豚。

1细节理解题。根据“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,科学家发现一种新的鲨鱼,它可以用鳍在珊瑚礁上“行走”。故选D

2细节理解题。根据“The platypus…and is as poisonous as a snake!(像蛇一样有毒)”可知,鸭嘴兽是有毒的。故选B

3推理判断题。通读最后一段,选项A意思是“它能用鳍走路”,文章未提到,故A不正确;根据“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,海豚曾经是四足陆生动物,随着它们在水中度过越来越多的时间,它们的后腿慢慢消失了,由此说明这只不寻常的海豚没有四只脚了,故B不正确;根据“It has an extra set of fins near its tail, about the size of human hands.”可知,它的尾巴附近有一组额外的鳍,故C正确,D不正确。故选C
