For years scientists have been worried about the effects of air pollution on the earth’s natural conditions. Some believe the air inside many houses may be more dangerous than the air outside. It may be one hundred times worse.

Indoor air pollution can cause a person to feel tired, to suffer eye pain, headache and other problems. Some pollutants(污染物)can cause breathing disorders, diseases of blood and even cancer. Most scientists agree that every modern house has some kind of indoor pollution.

People have paid more attention to the problem now. It is true that when builders began making houses and offices they did not waste energy. To do this they build buildings that limited the flow of air between inside and outside. They also began using man-made building materials. These materials are now known to let out harmful gases.

As the problem became more serious, scientists began searching for a way to deal with it. They discovered a natural pollution control system for building—green plants. Scientists do not really know how plants control air pollution. They believe that a plant’s leaves absorb(吸收)or take in the pollutants. In exchange the plant lets out oxygen through its leaves and tiny organizations on its roots. Scientists suggest that all buildings should have one large plant or several small plants inside for every nine square meters of space. Studies of different plants show that each absorbs different chemicals. So the most effective way to clean the air is to use different kinds of plants. Having green plants inside your house can make it a prettier and healthier place.

A.the limit of the flow of air between inside and outside

B.the building way that the builders want to save energy

C.the building things that are made of man-made materials

D.the man-made building materials and the limit of air-flow

4.The reason why we should use different kinds of plants to clean the air is that

A.plants can let out all kinds of pollutants indoors

B.plants may take in more oxygen (氧气)which people need

C.plants can absorb all kinds of harmful indoor chemicals

D.plants can make our houses prettier and more healthy

15.It happened to me recently.I was telling someone how much I had enjoyed reading Barack Obama's Dreams From My Father and how it had changed my views of our President.A friend I was talking to agreed with me that it was,in his words,"a brilliantly (精彩地)written book".However,he then went on to talk about Mr.Obama in a way which suggested he had no idea of his background at all.I sensed that I was talking to a book liar.
  And it seems that my friend is not the only one.Approximately two thirds of people have lied about reading a book which they haven't.In the World Book Day's"Report on Guilty Secrets",Dreams From My Father is at number 9.The report lists ten books,and various authors,which people have lied about reading,and as I'm not one to lie too often (I'd hate to be caught out),I'll admit here and now that I haven't read the entire top ten.But I am pleased to say that,unlike 42percent of people,I have read the book at number one,George Orwell's 1984.I think it's really brilliant.
  The World Book Day report also has some other interesting information in it.It says that many people lie about having read Jane Austen,Charles Dickens,Fyodor Dostoevsky (I haven't read him,but haven't lied about it either) and Herman Melville.
  Asked why they lied,the most common reason was to"impress"someone they were speaking to.This could be tricky if the conversation became more in-depth!
  But when asked which authors they actually enjoy,people named J.K.Rowling,John Grisham,Sophie Kinsella (ah,the big sellers,in other words).Forty-two percent of people asked admitted they turned to the back of the book to read the end before finishing the story (I'll come clean:I do this and am astonished that 58percent said they had never done so).

64.How did the author find his friend a book liar?D.
A.By judging his manner of speaking.
B.By looking into his background.
C.By mentioning a famous name.
D.By discussing the book itself.
65.Which of the following is a"guilty secret"according to the World Book Day report?B.
A.Charles Dickens is very low on the top-ten list.
B.42% of people pretended to have read 1984.
C.The author admitted having read 9books.
D.Dreams From My Father is hardly read.
66.By lying about reading,a person hopes toD.
A.control the conversationB.appear knowledgeable
C.learn about the bookD.make more friends
67.What is the author's attitude to 58% of readers?C.
A.Favorable.B.UncaringC.DoubtfulD.Friendly.
