问题 解答题
某工厂三个车间生产零件的情况如下,请你简单分析这三个生产车间的生产情况.
车间生产零件数/个合格零件数/个
24002280
24802335
23902272
答案

根据题意可知:这三个车间生产的零件个数都差不多,

第一车间的零件合格率:

2280
2400
×100%=95%;

第二车间的零件合格率:

2335
2480
×100%≈94.2%;

第三车间的零件合格率:

2272
2390
×100%≈95.1%;

因为95.1%>95%>94.2%,

所以第三车间的合格率最高,第二车间的合格率最低.

★The regular use of text messages and e-mails can lower the IQ more than twice as much as smoking marijuana(大麻). Psychologists say that sending/receiving messages or looking through the many menu options your mobile phone has, lowers a person’s IQ by almost 10 points. British researchers have named this situation “infomania”. Instead of fixed on what they are doing, people’s minds are constantly focused on reacting to the technology surrounding them. This means they don’t pay full attention to the work they are paid to do. The report also added that the brain can not do so many things at once. If you try to do too many things, mistakes begin to occur. And while modern technology can have huge benefits, too much use can be damaging not only to a person’s mind, but to their social life.

★The more televisions 4-year-old children watch, the more likely they are to become bullies later on in school, a newest U.S. study said. At the same time, children whose parents read to them, take them on outings and just generally pay attention to them are less likely to become bullies, said the  report from the University of Washington. Researchers also found gaps in learning and understanding such things as social skills early in life makes it more difficult for children to relate with other children. Watching violence on television leads to aggressive behavior.

★You could soon be able to add your favorite perfume to your e-mails. UK net provider Telewest Broadband is testing a system to let people send e-mails over the Internet with sweet smell. It has developed a kind of hi-tech air freshener that plugs into a PC and sprays a smell linked to the message. Telewest says it could be used by supermarkets to attract people with the smell of fresh bread or by holiday companies seeking to stir up images of sun-kissed beachers.
