Question

Unlike modern animal scientists, dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs in order to know how they lived and whether they were good parents. Instead, they have to search hard for information from dinosaurs’ fossils (恐龍化石) because dinosaurs died out millions of years ago.

It’s very difficult for the scientists to reach an agreement because different results can be got from the same fossils. Many fossils of the same kind of dinosaurs have been dug out from one place. They might have formed when an entire group of dinosaurs got stuck (陷入) all at once, or they might have been the result of dinosaurs getting stuck one after another over a course of a few centuries. Thus we can say that dinosaurs might have in the first case lived in big groups and in the second lived alone.

Though there are two different results, dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. “That’s pretty much settled at this point,” says Paul Sereno. A kind of dinosaurs called Sauropods left behind tracks in the western United States that appear to run north and south, suggesting that they even moved long distances together.

As to whether dinosaurs cared for their young, dinosaur scientists have turned to the closest living relatives of dinosaurs-birds and crocodiles-for possible models. Birds give a lot of care to their young, while crocodiles just help their young to the water. The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies, but we still cannot say that all dinosaurs did the same.

There is still a long way to go before the above questions could be answered. Dinosaur scientists, will have to find more proof to reach an agreement.

1.Dinosaur scientists can get information directly by .

A. studying dinosaur fossils

B. examining modern animals

C. watching dinosaurs

D. using telescopes

2.What is pretty much settled according to Paul Sereno?

A. Half of the dinosaurs lived alone.

B. Most dinosaurs moved long distances.

C. Many dinosaurs settled in the north.

D. Some dinosaurs lived in big groups.

3.Dinosaur scientists can probably know whether dinosaurs were good parents by .

A. watching many kinds of animals

B. studying dinosaurs’ living relatives

C. following the tracks left behind

D. working on dug-out dinosaur eggs

4.Which of the following is TRUE according to the 4th paragraph?

A. Birds hardly pay attention to their young.

B. Baby crocodiles can look after themselves well.

C. Some dinosaurs took care of their young.

D. Birds and crocodiles take good care of their young.

【解析】

試題分析：文章介紹了恐龍的一些知識(shí)。研究恐龍的專家無法實(shí)地考察恐龍，因?yàn)榭铸堃呀?jīng)滅絕了。他們只能從挖掘的化石中尋找信息。有關(guān)恐龍的知識(shí)目前沒有一致的結(jié)論，但可以肯定的是，一些恐龍過著群居生活。一些恐龍會(huì)照顧幼龍。

1.dinosaur scientists cannot sit on a hillside and use telescopes to watch dinosaurs ...they have to search hard for information from dinosaurs’ fossils”可知，研究恐龍的專家不能使用望遠(yuǎn)鏡實(shí)地觀察恐龍，他們只能努力從恐龍化石中尋找信息，故選A。

2.dinosaur scientists now generally agree that at least some kinds of dinosaurs lived in big groups. “That’s pretty much settled at this point,” says Paul Sereno.”可知，可以大致確定的是，一些種類的恐龍過著群居生活，故選D。

3.dinosaur scientists have turned to the closest living relatives of dinosaurs-birds and crocodiles-for possible models”可知，科學(xué)家轉(zhuǎn)向與恐龍有著近親關(guān)系的鳥類和鱷魚以查證恐龍是否是合格的父母，故選B。

4.Birds give a lot of care to their young”排除A；根據(jù)“while crocodiles just help their young to the water”可知，小鱷魚無法照顧自己，排除B；根據(jù)“Birds give a lot of care to their young, while crocodiles just help their young to the water.”可知，鱷魚不會(huì)悉心照顧幼崽，排除D；根據(jù)“The discovered fossils of dinosaurs sitting on their eggs and staying with their young suggest the parents were taking care of their babies,”可知，從已發(fā)現(xiàn)的化石中能夠看出，恐龍照顧幼龍，但不能一概而論地說，所有的恐龍都照顧幼龍，故選C。
