Question

【题目】

We usually see ancient plants or insects in amber(琥珀). But recently, a group of researchers found something unusual in amber — a feathered tail!

The tail includes bones, soft tissue and even feathers. It is 37 mm long, which is about the length of a matchstick. It looks like a plant at first sight. But researchers later identified(确定) it as part of the tail of a dinosaur that couldn’t fly almost 100 million years ago.

Xing Lida of Beijing’s China University of Geosciences discovered the amber in a market in Myanmar in 2015. “It is an amazing fossil(化石) and the finest details of feathers can be seen in 3-D.” he said.

The researchers note in their paper that this finding is particularly special because, although dinosaur feathers have been found in amber before, we don’t know which dinosaurs they came from. But this time researchers know more.

The tail is likely to belong to a tiny dinosaur called coelurosaur. Famous coelurosaurs include the T-rex(霸王龙) and Velociraptor(迅猛龙) — the latter of which would finally evolve into birds.

So with the “once in a lifetime” finding, can we hope for the possibility of a real Jurassic Park (侏罗纪公园)? In the movie series, scientists bring dinosaurs back to life by getting their DNA from blood found in amber.

But Canadian scientist Ryan Mckellar said that although soft tissue and blood of the tail were found in the amber, no genetic material was kept. “The Jurassic Park answer is still a ‘no’ — this is in the science fiction.” he said.

【1】What did a group of researchers find in amber recently?

A.Ancient plants.B.A tail of some ancient birds that couldn’t fly.

C.Ancient insects.D.A tail with feathers that belongs to a dinosaur.

【2】What do you know about the amber?

a. It is about 100 million years old. b. It was discovered in Myanmar.

c. It was discovered this year. d. It is a valuable fossil.

A.abB.bcC.acD.bd

【3】What does the underlined phrase “evolve into” in Paragraph 5 mean?

A.come intoB.break intoC.grow intoD.get into

【4】Why is the finding particularly special?

A.Because it is the first time that dinosaur feathers have been found in amber.

B.Because researchers know which dinosaur the tail might belong to.

C.Because researchers learned that Velociraotpors evolved into birds.

D.Because researchers learned that there were two types of coelurosaurs.

【5】The movie Jurassic Park is mentioned to .

A.talk about the use of DNA in this areaB.call on people to watch it

C.compare different dinosaursD.talk about science fiction

Answer 1

【答案】

【1】D

【2】D

【3】C

【4】B

【5】A

【解析】

本文介绍了最近研究人员发现，琥珀里有一些不会飞的古代鸟类的尾巴。这个研究结果非常特别，是因为研究人员知道尾巴可能属于哪种恐龙。

【1】细节理解题。根据But recently, a group of researchers found something unusual in amber — a feathered tail!和But researchers later identified(确定) it as part of the tail of a dinosaur that couldn’t fly almost 100 million years ago.可知，最近研究人员发现，琥珀里有一些不会飞的古代鸟类的尾巴，故选D。

【2】细节理解题。根据Xing Lida of Beijing’s China University of Geosciences discovered the amber in a market in Myanmar in 2015. “It is an amazing fossil(化石) and the finest details of feathers can be seen in 3-D.” he said.可知，这个琥珀是在缅甸发现的，是非常珍贵的化石，故选D。

【3】词义猜测题。根据前文的But researchers later identified(确定) it as part of the tail of a dinosaur that couldn’t fly almost 100 million years ago可知，以前这些恐龙不会飞，根据the latter of which would finally evolve into birds.后来成为鸟，会飞，这是表示进化了，成长为鸟，故选C。

【4】推理判断题。根据The researchers note in their paper that this finding is particularly special because, although dinosaur feathers have been found in amber before, we don’t know which dinosaurs they came from. But this time researchers know more.可知，这个研究结果非常特别，是因为研究人员知道尾巴可能属于哪种恐龙。故选B。

【5】推理判断题。根据But Canadian scientist Ryan Mckellar said that although soft tissue and blood of the tail were found in the amber, no genetic material was kept. “The Jurassic Park answer is still a ‘no’ — this is in the science fiction.” he said.可知，文中提到《侏罗纪公园》是为了谈论DNA在这个领域的应用。故选A。

认真阅读题干，根据题干要求，在文中寻找答案所在的语句或段落，进行分析理解，词义猜测，推理判断和概括归纳，选择正确的选项。例如小题2，根据Xing Lida of Beijing’s China University of Geosciences discovered the amber in a market in Myanmar in 2015. “It is an amazing fossil(化石) and the finest details of feathers can be seen in 3-D.” he said.可知，这个琥珀是在缅甸发现的，是非常珍贵的化石，故选D。
