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.
Most scientists agree that every modern house has some kind of indoor pollution. People began to notice the problem in the early 1970s. When builders began making houses and offices, they did not want to waste energy. To do this they built buildings that limited the flow of air between inside and outside. They also used man-made building materials which 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 believe that a plant's leaves absorb the pollutants (污染物). In exchange the plant lets out oxygen through its leaves. 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.

While many modern forms of communication like phone calls, e-mails, and letters, are extremely convenient, in my opinion, nothing beats speaking to another person face to face.
The first and most obvious advantage that a face-to-face communication has over a letter and
e-mail is that there is the ability to interactively converse. If the sender of a letter or an email does not write clearly, then much time must be spent in clearing up the misunderstanding. In a face-to-face conversation, misunderstandings are easily dealt with because of the interactive nature of it.
I would still argue that the face-to-face conversation is better because you can see the other person. Not all communication is verbal; the meaning of much of what we say depends on our body language and the tone of voice. Joking and irony are particularly difficult to express and enjoy without seeing the expression on someone’s face, or watching the movements of their body.
Finally, if the goal of communication is to maintain or deepen the relationship with someone, the face-to-face communication offers the choice of communication by touch even if we could communicate by the video. Trust and respect between business partners can be established with a firm handshake. No amount of body language can convey the excitement of a high five between friends, and no number of words can communicate the comforting embrace of a loved one. Touch is the first basic method of our human relationship before spoken language, and it is only available when people communicate face to face.
56. Which of the following is the best title for the passage?
A. How to communicate more effectively.
B. The importance of using body language in communication
C. Face-to-face communication, the best way of communicating
D. Comparison of different communication forms
57.Which of the following is NOT true in the passage?
A. A letter or e-mail is always written unclearly.
B. Business partners can show trust through a firm handshake.
C. During a conversation, body language is also important.
D. The face-to-face conversation is a way of communication.
58.The author’s attitude towards forms of communication is .
A.Modern forms of communication like phone calls and e-mails are extremely convenient.
B. Traditional ways of communication are out of date and should fall into disuse.
C. Face-to-face communication can only be used among strangers.
D.Face-to-face communication has advantages over the other ways of communication.

A.Goods for auction (拍卖) sales
B.Definition of bidding
C.Way to sell more goods by auction
D.Auction sales in history

  E. Brief introduction to auctions
  F. Making a larger profit as an auctioneer
61. ______
Auctions are public sales of goods, conducted by an officially approved auctioneer. He asks the crowd assembled in the auction-room to make offers, or “bids”, for the various items on sale. He encourages buyers to bid higher figures, and finally names the highest bidder as the buyer of the goods. This is called “knocking down” the goods, for the bidding ends when the auctioneer strikes a small hammer on a table at which he stands.
62. ______
The ancient Roman probably invented sales by auction, and the English word comes from the Latin auction, meaning “increasing”. The Romans usually sold in this way the goods taken in war. In England in the eighteenth centuries, goods were often sold “by the candle”: a short candle was lit by the auctioneer, and bids could be made while it stayed alight.
63. ______
Practically all goods whose qualities vary are sold by auction. Among these are coffee, skins, wool, tea, furs, silk and wines. Auction sales are also usual for land and property, furniture, pictures, rare books, old china and similar works of art.
64. ______
An auction is usually advertised beforehand with full particulars of the articles to be sold and where and when they can be viewed by potential buyers. If the advertisement cannot give full details, catalogues are printed, and each group of goods to be sold together, called a “lot”, is usually given a number. The auctioneer need not begin with Lot 1 and continue in the order of numbers: he may wait until he notices the fact that certain buyers are in the room and then produce the lots they are likely to be interested in.
65. ______
The auctioneer’s services are paid for in the form of a percentage of the price the goods are sold for. The auctioneer therefore has a direct interest in pushing up the bidding as high as possible. He will not waste time by starting the bidding too low. He will also play on the opponents among his buyers and succeed in getting a high price by encouraging two business competitors to bid against each other.

Mr William Shakespeare and the Internet
Explanation of Contents
This is the fourth edition of these pages. It is hard to believe, but once again they are new and improved. My motive in publishing these pages remains to help and stimulate others in Shakespeare studies, and especially those who might contribute their work to the Internet. The spirit of altruism (利他主义) that originally built the Internet is not quite gone, though, sadly, through the pressure of time and profit has lessened.
A major new addition to the pages is a Shakespeare Timeline, which is an online biography mounted at this site. The problems with searching for Shakespeare resources using the available Search Engines are:
---- It is difficult to focus most searches so that you get a manageable number of relevant hits;
---- It is impossible by simply reading an abstract to make any distinction between the output of a Junior High School student and that of a professional researcher.
Another change in these pages over previous editions is the “What’s News” page. If you come away from these pages with the feeling that they are very useful but slightly pedantic (学究的), I will have realized my goal.
An Apology
I am continually apologizing to the many who have written me requesting revisions of the pages. We are all too busy. I simply have not had the time to dedicate to these pages that I wish. But I love the material and so have, at long last, made some time to update them.
A Reminder to Young Students
These pages contain the best links I can find to Shakespeare on the Internet. As a reminder, I would say I very much enjoy hearing from people who view and use these pages. If you want to do Shakespeare research using the web, this page is a great starting point, and I keep it as current as I can. The web is in its infancy in bringing good, scholarly content to students. Don’t forget the best, if not quickest, resources are still in your library.

D. Shakespeare researchers should first of all refer to these pages.

When early colonial settlers went to America, they took many forms of dance to their new home. Square dancing, one of the oldest forms of American folk dancing, developed from several different Old World group dances, mainly English country dances, and the French quadrille(四对方舞).
In the American version of square dancing, four couples form a square and dance to music. An American addition to square dancing is the caller. What do you think a caller does?
The callers---someone who calls out the dance steps in time to the music--- was a completely American invention. At first dancers memorized all the steps for a particular dance, but eventually the dances became so complicated that it was necessary to have someone call out cues (提示) so that dancers didn’t have to remember so many steps. The caller didn’t just call out “do-se-do your partner”; a good caller also came up with colourful sayings or witty lines that he said in between the cues such as “Don’t be shy and don’t be afraid. Swing on the corner in a waltz promenade (步伐).” A caller might also come up with new dance steps and routines.
Although popular for years, square dancing seemed to be going out of style and fading away until the early 1930s, when Henry Ford helped revive interest in it. Ford, the automobile manufacturer, used to vacation at the Wayside Inn in Massachusetts, where he enjoyed the dance programme run by a man named Benjamin Lovett. Ford asked Lovett to come to Detroit and teach dances, but Lovett said he couldn’t because he had a contract with the inn. Ford solved that problem by buying the inn and Lovett’s contract. He took Lovett back to Detroit, where together they established a programme for teaching squares and rounds. Square dancing was updated and groups began forming all over the country.

A. The Different Steps of Square Dancing
B. The Origin and Development of Square Dancing

D. Why Did Square Dancing Go Out of Style?
54. What does the underlined part “their new home” refer to?
A. The United Kingdom.B. France.
C. Africa.D. America.
55. Why did the caller call out the steps for the dancers?
A. Because the dance was invented by the caller.
B. Because the dancers didn’t know the names of the steps.
C. Because the steps were very particular.
D. Because it was hard for the dancers to remember all the steps.
56. Why did the author mention Henry Ford in the last paragraph?
A. Because he was the man who made the first car.
B. Because he was vey fond of dancing.
C. Because he helped make square dancing popular again.
D. Because he taught people how to dance.

How do successful people think? What drives them? Interviews and investigations indicate that there are several keys to success that successful people share.
First of all, successful people never blame someone or something outside of themselves for their failure to go ahead. They realize that their future lies in their own hands. They understand that they cannot control things in life, such as nature, the past and other people. But in the meantime, they are well aware that they can control their own thoughts and actions. They take responsibility for their life and regard this as one of the most empowering things they can do. Perhaps what most separates successful people from others is that they live a life “on purpose”---- they are doing what they believe they are put here to do. In their opinion, having a purpose in their life is the most important element that enables them to become fully functioning people. They hold that when they live their life on purpose, their main concern is to do the job right. They love what they do ---- and it shows. People want to do business with them because of their commitment(忠诚). To live their life on purpose, successful people find a cause they believe in and create a business around it. Besides, they never easily give up. Once they have set up goals in their life, they are willing to work hard whatever it takes to achieve their goals. Top achievers always bear in mind what they don’t have.
Rather than be negative or depressing, they use the knowledge to spur themselves on and go after what they want energetically and passionately.
46. The underlined word “it ” refers to “____”.
A. the main concern of successful people
B. the job that successful people do
C. the commitment with which successful people do their jobs
D. the business that successful people do with other people
47. By living a life “on purpose”, successful people can do the following EXCEPT ____.
A. do a lot of work
B. concentrate on their jobs
C. do business with many people
D. control things in life
48. The underlined word “spur ” most probably means “____”.
A. encourage B. exciteC. relieve D. compel
