Question

【題目】Dinosaurs ruled the planet for millions of years, and they are generally believed to have gone extinct.But the reality is that modern versions of dinosaurs are all around us. Scientists have been exploring similarities between birds and dinosaurs; and new research shows that these two types of animals are directly linked.

The connections between birds and dinosaurs are explored in a new museum exhibit called Dinosaurs Among Us at the American Museum of Natural History in New York City.

According to Mark Norell, the director of the exhibit and an expert at the museum, it is based on new scientific evidence collected over the last two decades. "I think this is really going to shake up the way people think of dinosaurs “ Norell told reporters.” One could argue that we still live in the age of dinosaurs."

The exhibit includes ancient fossils and lifelike models of dinosaurs of all sizes to show the evolution of dinosaurs into birds. It examines several properties that are shared between the two species, including feathers, complex brains, the shapes. And sizes of eggs, and the ability to fly. Birds today make nests, lay eggs and tend to babies. Fossil research shows that some dinosaurs also made nests and laid eggs. Also，birds have hollow（中空的）bones, which don’t weigh much and allow birds to take more air into their lungs. These adaptations help with flight. Some dinosaurs had these properties as well. In addition, the exhibit shows that there are many similarities between the legs, claws; and feet of dinosaurs and birds.

Norell noted that the research behind this exhibit is the result of advanced scientific, techniques; and new technologies. For example researchers used a scanning (掃描) process called computed tomography (CT) to look inside the brains of extinct dinosaurs. It combines with many X-rays to produce a 3D image. "Modern technology tells us more than we thought

we could ever know about the connections between dinosaurs and birds," Norell said.

Answer 1

【答案】

【1】D

【2】B

【3】B

【4】C

【解析】科學(xué)家們一直在探索恐龍和鳥類的相似性，新的研究表明這兩種生物有可能有直接的相關(guān)性。

【1】主旨大意題。第一段引出話題，第二段陳述主旨The connections between birds and dinosaurs are explored in a new museum exhibit called Dinosaurs Among Us at the American Museum of Natural History in New York City. 鳥類和恐龍的聯(lián)系在一個叫做Dinosaurs Among Us的博物館展覽上被探索。下文陳述這兩種生物的相似點，可知文章主旨即是一個展示顯示了恐龍和鳥類的相似。故選D。

【2】詞義猜測題。根據(jù)劃線單詞所在的句子It examines several properties that are shared between the two species, including feathers, complex brains, the shapes.它比較了這兩種物種共有的幾個properties，根據(jù)句中列舉的properties “羽毛，復(fù)雜的大腦，形狀”這些都屬于這兩個物種的特征，故選B。

【3】細節(jié)理解題。根據(jù)文章第四段，通過比較恐龍和鳥類這兩個物種，發(fā)現(xiàn)它們有很多的相似性，它們都能筑巢，下蛋，此外鳥類有中空的骨頭，減少重量并能允許鳥類吸入肺部更多的空氣，這些都幫助鳥類飛翔，一些恐龍也有這些特征。故題干所問“恐龍和鳥的其中一個相似性”，可知答案為B（很輕的骨頭）。

【4】推理判斷題。Norell提到的CT技術(shù)是作為最后一段第一句Norell noted that the research behind this exhibit is the result of advanced scientific, techniques; and new technologies.（這個展覽背后的研究是先進科學(xué)技術(shù)的結(jié)果。）的例子陳述的，可推斷Norell提到的CT技術(shù)是為了顯示現(xiàn)代技術(shù)的應(yīng)用，故選C。
