We can only make a guess, of course, but we can be sure that he will be different from what he is today, for man is slowly changing all the time. Let us take an obvious example. Man, even five hundred years ago, was shorter than he is today. Now, on average, men are about three inches taller, so we may assume   that man will continue to grow taller. Again, as time goes on, we shall have to use our brains more and more. This is likely to bring about a physical change to the head, in particular, the forehead will grow larger. Nowadays our eyes are in constant use. In fact, we use them so much that very often they become weaker and we have to wear glasses. But over a very long period of time it is likely that man's eyes will grow stronger. On the other hand, we are likely to make less use of our arms and legs, which, as a result, are likely to grow weaker. At the same time, however, our fingers will grow more sensitive because they are used a great deal in modern life. But what about hair? This will probably disappear from the body altogether in course of time because it does not serve a useful purpose any longer. Perhaps all these give the impression that in the future man will not be a very attractive creature to look at! This may well be true. All the same, in spite of all these changes, future man will still have a lot in common with us. Question: According to the passage, we can learn that   _  . Options: A: human beings will become less attractive in the future B: less use of a part of the body will become weaker C: human beings hope for a change in the future life D: future life is always predictable

Article: Life on-line can be a much richer experience when you aren't restricted to just written words and still pictures.Even if you're new to the Net,you've probably heard about multimedia on-line--listening to audio,watching animations and videos,even playing in three-dimensional space.Sound and movement make information come alive. To experience it,you'll need special pieces of software called plug-ins.The term "plug-in" refers to a small,add-on piece of software which extends the capabilities of your web browser,like Netscape Navigator or Microsoft Explorer,turning your computer into a radio or TV. When you arrive at a web page which contains a file requiring a plug-in which you don't have,you will usually receive a message asking if you want to get it by downloading it and installing it into your computer.Most of the time,the installation will be automatic. Occasionally,you'll run into a downloaded file which needs to be decompressed or un-zipped before installation.Once installed,plug-ins run automatically,without you having to do anything. Many multimedia controls still need to be obtained from the developer but are installed automatically. Shockwave is a good example of this.All you need to do is go to the Macromedia site and click on the link to install the ActiveX control.The rest happens automatically.The next time you go to a "Shocked" website,the Shockwave control loads and plays the movie. Most plug-ins and controls can be downloaded for free on the Internet,although not all will work with every system.Some of them,for instance,only work with Windows 95. Question: Plug-ins can help us to do all of the following except   _  . Options: A: listening to music B: watching animations and videos C: playing three-dimensioned games D: searching for information on the net

Read the article and select the best answer. Article: Four hundred years ago, an Italian scientist named Galileo Galilei became the first person to see the craters  on the moon. Galileo was one of the first people to use a telescope to study the sky. Since then, telescopes have become the most important tool used by astronomers. Scientists never stop finding new ways to make these instruments more powerful. In the next several years, two new telescopes with different purposes are to be used.     One of the telescopes, called Pan-STARRS, could save humans from dying out. Nick Kaiser, a scientist who works on the project, says the Pan-STARRS telescope has been designed to find "90 percent of all killer asteroids  near Earth".    Pan-STARRS, like most telescopes, uses mirrors and lenses  to provide pictures of outer space. Giant mirrors are used to "gather" light. They reflect the light onto the lens of a camera, which can then record the image.     When completed, Pan-STARRS will include four telescopes which will be put on top of a mountain on the Hawaiian island of Maui. Only one telescope is in place and working now. Each telescope will take pictures of one patch of sky for about 30 seconds, and then move on to another patch. Every night, each telescope will take pictures of about 1,000 patches. Every week, each telescope will have photographed the whole sky.     Each of the four telescopes will take pictures of the same patches of sky. One telescope, working alone, may sometimes incorrectly show an asteroid. If there are three other telescopes working, astronomers can use them to see if there really is an asteroid coming our way. By using four telescopes instead of one, scientists hope to get a better picture of space. If a giant asteroid was identified, astronomers would try to break it up long before it reached Earth. Question: How many patches is the whole sky divided into when Pan-STARRS is working? Options: A: 1,000 B: 7,000 C: 21,000 D: 28,000
