Wherever you go you can see people using cell phones. Many college students, even high school students, have cell phones. Cell phones have brought people a lot

15、 of benefits, but the most important is that they are convenient. With cell phones in their hands, they can keep in touch with anybody they want.

23、dream has come true in many fields thanks to rapid development in artificial intelligence research. Wonderful as this seems, machines have problems.To begin with, people lose jobs when machines take their places, especially in the mass production industry such as automobile business. In factories of

24、 the famous car company Ford, almost every step of car making is done by giant robots that work faster with higher reliability and precision than human labor. Because of the adoption of robots, thousands of workers are put out of their old jobs and forced to make changes in their work. Even such cha

25、nges create job opportunities because robots need people to take care of and operate; the number of new jobs is much smaller than that of lost, thus causing huge pressure on the labor market and government. People become less smart because of the wide use of machines in their life. Nowadays people n

26、eed to use their brain less than they did in the past. Everything is programmed and the only thing we need to do is to push a button or throw on a switch. This has given us great convenience but made us lazier and less smart. Everyone has the awkward moment troubling with the spelling of a simple wo

27、rd when writing with a pen. But with a computer, it will automatically proofread the spelling and grammar of your writing. So people become less concerned with learning things right.

New produces are being conceived every minute of every day, all of which will impact people in some respects. Ho

31、wever, in all these technologies and produces computers have been the most important influences on people. Some people assert that computers have made life more complex and stressful, while some people believe that computers have made life easier and more convenient. From my point of view, the advan

32、tages of computers are the leading sides and computers become a necessary part in peoples lives. Perhaps computers may quicken our pace of life and make our life more complex and stressful. With the development of computers almost every jobs need people who are well up in computer technology. People

33、, who want to find a good job, must learn how to use computers. On one hand, the computer technology is a very complex subject. If you want to use computers very well, you must take a lot of time to study and practice it. On the other hand, computers develop so fast that people must study new techno

34、logy constantly. Those all make people feel stressful. Even though there may be one or two disadvantages to develop computers, the advantages fast outweigh them. The major point for my penchant for computers is that computers can help people do many things, including complex computation, storing and

35、 searching information and some work that is dangerous for people to do. For instance launching a rocket up to outer space needs so complex computation that people cannot do it without computers; searching the newest information is of vital importance for business, so people will not be success in b

36、usiness without computers. Computers have facilitated many of our working processes and we have already grown dependent on them. Another advantage of computers is that people can use them for entertainment in spare time. From pc games to online chatting, computers have the ability to entertain us in

37、 a wide verity of ways. After a busy day, playing pc games is the favorite thing of most of my classmates. And in todays life, a lot of young people could have not televisions, but they must have a set of computer. Now many films display fascinating images by using computers to deal with them. In a

38、word in spite of the fact the computer appears to have made life more complex and stressful, I fell that the advantages are more obvious. Computers have become an integral part of everyday life. They can help us do much work and make us funny.核能的利弊Nuclear power plants provide about 17 percent of the

39、 worlds electricity. Some countries depend more on nuclear power for electricity than others. In France, for instance, about 75 percent of the electricity is generated from nuclear power. There are more than 400 nuclear power plants around the world. To build a nuclear reactor (核反應(yīng)堆),what you need i

40、s some mildly2 enriched uranium(鈾). Uranium is a fairly common element on Earth,incorporated3 into the planet during the planets formation(形成). U-235 is one of the few materials that can undergo4 induced fission(誘發(fā)性核裂變). Raising and lowering the control rods(桿，棒條) allow operators to control the rate

41、 of the nuclear reaction. When an operator (操作員) wants the uranium core to produce more heat, the rods are raised out of the uranium bundle(捆，束). To create less heat, the rods are lowered into the uranium bundle. The rods can also be lowered completely into the uranium bundle to shut the reactor dow

42、n in the case of an accident or to change the fuel. The uranium bundle acts as an extremely high-energy source of heat. It heats the water and turns it to steam. The steam drives a steam turbine(汽輪機(jī)), which spins5 a generator(發(fā)電機(jī)) to produce power. Well-constructed nuclear power plants have an impor

43、tant advantage when it comes to electrical power generationthey are extremely clean. Compared with a coal fired power plant, nuclear power plants are a dream come true from an environmental standpoint (立場，觀點(diǎn)). Unfortunately, there are significant problems with nuclear power plants. Mining and purify

44、ing(提純) uranium has not, historically, been a very clean process. Improperly functioning nuclear power plants can create big problems. The Chernobyl6 disaster is a good example. Spent fuel from nuclear power plants is toxic (有毒的) for centuries, and, as yet, there is no safe, permanent(永久的) storage f

45、acility for it.The nuclear crisis in Japan has developed rapidly, which makes us to think over about exploration of nuclear power. Fears about nuclear safety which took a generation to overcome have appeared again.Supporters of nuclear power say nuclear power produces nearly no conventional air poll

46、ution, which is called as clean energy”. Besides, our technology develops quickly. Therefore, risks such as natural disaster can be avoided. we can benefit from the exploration of nuclear power.However, opponents worry that the complexity of design and engineering of nuclear plants(核電站)Any failure or operation error could lead to serious result. It will pollute soil and plants and do harm to humans and animals. In my eyes, we should continue the exploration of nuclear power. Not only does it bring lots of
