1.根据以下资料，回答14-16题。 　　Many people use wood stoves and fireplaces to heat their homes．Scientists have become worried about the smoke that they give off．Harmful chemicals are in the smoke．The smoke is causing air pollution．The pieces of pollution, called soot, are floating in the air．They are too tiny to see．Scientists must use a microscope to see them. 　　Small amounts of soot are safe, but large amounts can be dangerous．The govenment wants to limit this kind of pollution．It may stop people from using their fireplaces. 　　The air is tested every day．When soot levels are high, more than 65 micrograms of soot per cubic meter, factories must stop making smoke．The government thinks that limit should be much lower. Factories produce the most smoke and soot．But the government thinks that all types of burning should be limited．The soot levels from factories and homes could be limited．Home owners may have to install new wood stoves that they comply with the new law．Or, they may not be able to bum on days when the air quality is bad. 　　Residents of some towns are fined if they violate the burning ban．Scientists hope these new regulations will make the air cleaner and less harmful to breathe.16 Why is the air quality tested every day?

3.The year 2000 will bring big changes in communication．Cell phones will be small enough to carry in your pocket．Videophones will let you see the person you are talking to on the phone．Tiny hand size computers will know your favorite subjects．The Internet and email will be everywhere． 　　Technologists believe 2000 will be the year of video messaging．You will be able to see whom you're talking to. 　　Also in the near future small wireless boxes will pick up information from satellites．In 5 years, computers won't need to be connected through wires. 　　All of this will be good for rural areas and countries that don't have cable or telephone now． 　　In 20 years you may only need to think about something and the computer will do it. 　　Constance Hale is the author of Sin and Syntax, "I believe that email has been an incredible boon to communication．People are writing today where they would have been telephoning yesterday．So people are engaging with words more than they have for the last couple generations." If people use email and the Internet more, it could make people better readers and writers．Some people think the most important part of communication is to make people understand each other better．Will technology make that easier? 　　The translator also comes in handy in medical emergencies．Tam Dinh says, "Where people are injured it's always important to get as much information as quickly as possible." 　　Bob Parks is an Associate Editor of Wired Magazine, "Bob's morning begins at about 6:45 am．and Bob is kind of mad, because Bob usually gets up at around 7:15 and likes to cut it close with his morning commute, but I look at my radio and it says that there's a traffic jam on 101 South and I'm gonna need an extra 1/2 hour．And so my radio has got a net connection, wireless net connection as well as a good old power cord to the wall and it has received notice that there's a traffic jam and it has calculated an extra 1/2 hour commute time." 　　Some day everything may be connected to the Internet．Your refrigerator will add milk to your Internet grocery list when the date on the carton has passed．Light bulbs will be ordered before they burn out. 　　It's fun to try to guess the future．Usually the predictions are wrong．The one thing we know for sure is that we can't imagine how technology will change.[单选题] How will wireless computers and Internet services help rural areas?

4.There is one thing that everyone wants more than anything else．Some people try to get it by making money．They think that when they have enough money to buy such things as houses, farms, and cars, they will have the one thing that everyone wants. 　　Other people believe that if they know enough they will find this thing．They study all their lives in search of it．Still others think that if they have power, they will find this thing．They keep telling themselves: when I am a boss, I will no longer have to search for this thing． 　　What is it that everyone wants more than anything else? What is it that all of us keep working and striving for each day? It is happiness. 　　　Happiness is a strange thing．It does not mean the same to all men．What will make one man happy may not make another man happy．Some men say that happiness comes from helping others; other men say that happiness comes from making life more pleasant for everyone．What do you mean when you say "That makes me happy"? 　　Read what different people have said about happiness．Perhaps you will learn something that will bring you peace of mind, comfort, money or it may bring you what you search for --happiness．"Some people try to get it by making money." The underlined "it" means __.

J.EdgarHoover quietly went ahead with his plans.He picked his men carefully.They had to be between the ages of twenty-five and thirty-five.He wanted only men withgood manners and good character.When working ashis officers they would have to meetall kinds of people.Hoover wanted men who could handle a teacup as well as a gun.Hechose men so carefully that he made theFBI the hardest service in the world to get into.The FBI cannot help in every police problem.It can look into only certain crimes againstthe government.Solving all other crimes is the duty of local police forces.2.Before he worked with the FBI.J.Edgar Hoover wasa（）

Number sense is not the ability to count．It is the ability to recognize a46in number．Human beings are born with this ability．47, Experiments show that many animas are, too．For example, many birds have good number sense．If a nest has four eggs and you remove one, the bird will not48．However, if you remove two, the bird49leaves．This means that the bird knows the50between two and three.

Another interesting experiment showed a bird’s51number sense．A man was trying to take a photo of a crow(乌鸦) that had a nest in a tower, but the crow always left when she saw him coming．The bird did not52until the man left the tower．The man had an53．He took another man with him to the tower．One man left and the other stayed, but they did not54the bird．The crow stayed away until the second man left, too．The experiment was55with three men and then with four men．But the crow did not return to the nest until all the men were56．It was not until five men went into the tower and only four left that they were57able to fool the crow.

How good is a human’s number sense? It’s not very good．For example, babies about fourteen months old almost always notice if something is taken away from a58group．But when the number goes beyond three or four, the children are59fooled.
