Once Wilhelm K. Roentgen and several other scientists were experimenting with passing electric currents through certain gases in a special glass tube from which the air had been taken away. Then one day Roentgen noticed that when the tube was covered with black paper, some strange kind of radiation was coming through and making a screen nearby glow(发光). Roentgen could see anything out of the tube, but then he discovered that if he put the screen at the next room on the other side of a closed door, the rays still seemed to affect it. The glowing screen showed that the rays could pass not only through the black paper but also through wood.
The next thing he found out was that if he put his hand between the rays and a photographic
plate, the rays would print a shadow of the bony(骨头的) framework of his hand on the plate. In fact, the rays could pass as easily through the fleshy part of his hand as through the black paper. But hardly at all through the bone. So Roentgen made the first X-ray picture of a hand showing just how the bones in the hand fitted together.
Roentgen called the unknown rays X-rays, but other scientists called them Roentgen rays in
Roentgen discovered X-rays ___________.
A.by working hard B.by chance
C.by doing experiment after experiment D.with the help of several other scientists
What was in the special glass tube?
A.Air B.Nothing C.Nothing but gases D.None of the above
We may conclude that the rays Roentgen found were __________.
A.dangerous B.invisible C.colorful D.poisonous
What could X-rays hardly pass through?
A.Wood B.Glass C.Bones D.Black paper
Which title best gives the main idea of the passage?
A.the Discovery of Roentgen Rays. B.The Discovery of Electric Currents.
C.The First X-ray Picture of a Hand. D.The Use of the Photographic Plate.

A recent study, while showing a generally positive attitude toward science, also suggests a widespread worry that it may be “running out of control”.This idea is dangerous.
Science can be a force for evil as well as for good.Its applications can be channeled either way, depending on our decisions.The decisions we make, personally or collectively, will determine the outcomes of science.But here is a real danger.Science is advancing so fast is so strongly influenced by businesses that we are likely to believe whatever decisions we come to will make little difference.And, rather than fighting for the best possible policies, we may step back and do nothing.
Some people go even further.They say that despite the moral and legal objections (反对), whatever is scientifically possible will be done ——somewhere, sometime.They believe that science will get out of control in the end.This belief is dangerous too, because it a fuels sense of hopelessness and discourages them from making efforts to build a safer world.
In our interconnected world, the lack of agreement in and of the world of science can lead to the failure to control the use of science.Without a common understanding, the challenges of “controlling” science in this century will be really tough.Take human cloning for example.Despite the general agreement among scientists on its possible huge impact (影响) on traditional moral values, some countries still go ahead with the research and development of its related techniques.The outcomes are hard to predict.
Therefore, discussions on how science is applied should be extended far beyond scientific societies.Only through the united efforts of people with hope, can we be fully safe against the misuse of science and can science best serve mankind in the future.
What can we conclude from the recent study?
A.People think highly of science.
B.People hold mixed opinions about science.
C.Science is getting dangerously out of control.
D.Science is used for both good and bad purposes.
According to the passage, what will happen if we hold that science is getting beyond control?
A.The development of science will hopelessly slow down.
B.Businesses will have even greater influence on science.
C.The public will lose faith in bringing about a bright future.
D.People will work more actively to put science under control.
The discussion should reach beyond scientific societies because __________.
A.scientists have failed to predict the outcomes
B.the ties between different areas need strengthening
C.united efforts are necessary for the development of science
D.people need to work together to prevent the bad use of science
What is the main idea of the passage?
A.Science and its applications bring us many dangers.
B.The development of science mostly lies in people’s attitudes.
C.Mankind can largely take control of science with their efforts.
D.The future of science will be influenced by the dangerous ideas.

阅读下面短文,从短文后各题所给的四个选项(A、B、C和D)中,选出可以填入的空白处的最佳选项,并从答题卡上将该选项涂黑。
You have waited 45 minutes for the valuable 10 minutes’ break between classes. But when the bell for the next class rings, you can’t 36 how quickly time has passed.
If you are familiar with this 37 , you’ll know how time flies when you are having fun-and 38 when you are bored. Now scientists have 39 a reason why this is the case.
Scans have shown that patterns of activity in the brain 40 according to how we focus on a task. When we are 41 , we concentrate more on how time is passing. And this makes our brains 42 the clock is ticking more slowly.
In an experiment 43 by a French laboratory, 12 volunteers watched an image 44
researchers monitored their brain activity.
The volunteers were told to 45 concentrate on how long an image appeared for, then
46 the color of the image, and thirdly, study both duration and color. The results showed that 47 was more active when the volunteers paid 48 subjects.
It is thought that if the brain is 49 focusing on many aspects of a task, it has to 50 its resources, and pays less attention to the clock. 51 , time passes without us really 52 it, and seems to go quickly. If the brain is not so active, it concentrates its 53 energies on monitoring the passing of time. 54 , time seems to drag.
Next time you feel bored 55 , perhaps you should pay more attention to what the teacher is saying!
