Question

【題目】

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(確定) 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(霸王龍) and Velociraptor(迅猛龍) — 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 (侏羅紀公園)? 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.

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】

本文介紹了最近研究人員發(fā)現(xiàn)，琥珀里有一些不會飛的古代鳥類的尾巴。這個研究結(jié)果非常特別，是因為研究人員知道尾巴可能屬于哪種恐龍。

【1】細節(jié)理解題。根據(jù)But recently, a group of researchers found something unusual in amber — a feathered tail!和But researchers later identified(確定) it as part of the tail of a dinosaur that couldn’t fly almost 100 million years ago.可知，最近研究人員發(fā)現(xiàn)，琥珀里有一些不會飛的古代鳥類的尾巴，故選D。

【2】細節(jié)理解題。根據(jù)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，這個琥珀是在緬甸發(fā)現(xiàn)的，是非常珍貴的化石，故選D。

【3】詞義猜測題。根據(jù)前文的But researchers later identified(確定) it as part of the tail of a dinosaur that couldn’t fly almost 100 million years ago可知，以前這些恐龍不會飛，根據(jù)the latter of which would finally evolve into birds.后來成為鳥，會飛，這是表示進化了，成長為鳥，故選C。

【4】推理判斷題。根據(jù)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，這個研究結(jié)果非常特別，是因為研究人員知道尾巴可能屬于哪種恐龍。故選B。

【5】推理判斷題。根據(jù)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《侏羅紀公園》是為了談?wù)?/span>DNA在這個領(lǐng)域的應(yīng)用。故選A。

認真閱讀題干，根據(jù)題干要求，在文中尋找答案所在的語句或段落，進行分析理解，詞義猜測，推理判斷和概括歸納，選擇正確的選項。例如小題2，根據(jù)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，這個琥珀是在緬甸發(fā)現(xiàn)的，是非常珍貴的化石，故選D。
