高二英语单项填空简单题查看答案及解析

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 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 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 distance.

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 living relatives    B. studying dinosaurs’ living relatives

C. watching birds flying                 D. working hard in labs

4. Which of the following is TRUE according to the 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.

Do you suppose Darwin, one of the greatest scientists of all time, really did foolish experiments? Or did he do experiments that were so simple and basic that other people just thought they were foolish?

Sometimes, people think they already know the answer to a question or the solution to a problem. Sometimes, they really do know an answer or a solution, but without thinking they are important.

Charles Darwin didn’t settle for(满足于)just thinking he knew something. And, he believed all things could be important however simple they seemed to be.

Suppose you drop sheets of paper that are of exactly the same size and shape. If you drop them at the same time in the same place, they will fall in the same way. Now make one of the sheets of paper into a tight little ball and let it drop along with the other sheets. What happens? You have done an experiment that is so simple that you might think it couldn’t be worth anything.

But this simple experiment is important. It explains part of our present-day understandings of physics, ideas that were worked out long ago by Galileo and Newton. And these understandings set aside some of ancient Greek physics.

Scientists sometimes stop to look at very simple things and to think very hard about them. Even the simplest idea, which we might think is foolish, can shake the foundations of science.

1.The passage tells us that Charles Darwin　　　.

A.was a great English scientist

B.always liked doing the experiments that others thought difficult

C.thought even the simplest thing was important

D.didn’t get well with others

2.The underlined phrase “set aside” most probably means　　　.

A.throw away B.store up

C.put to use D.realize

3.The author of the passage tries to　　　.

A.convince us that Charles Darwin, Galileo and Newton are the greatest scientists in the world

B.draw the conclusion that basic sciences are simple things

C.prove that two sheets of paper, with the same size and shape, will fall at the same speed

D.draw our attention to everyday happenings around us

4.Which of the following is TRUE?

A.Darwin really did foolish experiments.

B.According to some people Darwin did foolish experiments.

C.It is believed by all the people that things could be important though they seemed to be simple.

D.Galileo and Newton worked out ancient Greek physics.
