Apparently,we are safe neither at home nor in the business office.We use water in both places,but the research shows that chemicals added to our local water supply to kill harmful bacteria can have unwanted side effects.These chemicals can cause potential harm through drinking and in seemingly harmless activities as cleaning one’s house.They are released(set free)from water by daily actions like water running out of tap,spraying from garden pipes,or splashing in dishwashers and washing machines.As the water is moving.these chemicals are released into the air and then breathed in. Once inside our bodies, they start to affect our health.
Does this mean we should stop bathing? No, say the scientists, but we should put all pollution into perspective. Activities at home such as the burning of coal, cooking oil, or even candles release carbon monoxide and particulates such as cigarette ashes which have been proven as harmful to health as working or living near heavy traffic. New tugs, bedding, and even clothing give off that“new smell, ”which is a sure sign of chemicals. In the office, newly applied paint, newly purchased telephones and other telecommunications equipment, and computers release polluting chemicals, too. As offices and homes often have inadequate ventilation (通风), these chemicals can build up to become health problems. Their poisonous effects are only now being slowly recognized.
These facts suggest that, at a minimum, proper airing of newly purchased goods with an obvious chemical smell is a wise warning. Home and office windows should be opened during good weather. Even one’s car needs to be ventilated as well while in the garage.
We need further research to understand better other potential health dangers, too. For example, the effects of overcrowding of schools (carbon dioxide build-up ), the factory work environment ( an endless list of potentially dangerous substances ), and even home heating and cooling (the air conditioner may be our enemies, not our friends) have only recently started to come to light. Until we understand the effects of our new technological environment better, we can only hope that“there is no place like home.”
1.What is the main idea of the first paragraph?
A.The air we breathe in is harmful.
B.Chemicals are released in the running water.

2..In Paragraph 2, the underlined sentence means that .
A. homes and offices should be aired often
B. any pollution should be taken into consideration
C. bathing should be done with caution
D.we should prevent any pollution from doing harm to us
3.What is the purpose of the passage?

查看习题详情和答案>>Banks are not ordinarily prepared to pay out all accounts(账,账户); they rely on depositors (储户) not to demand payment all at the same time. If depositors should come to fear that a bank is not safe, that it cannot pay off all its depositors, then that fear might cause all the depositors to appear on the same day. If they did, the bank could not pay all accounts. However, if they did not all appear at once, then there would always be enough money to pay those who wanted their money when they wanted it. Mrs. Elsie Vaught has told us of a terrifying bank run that she experienced. One day in December of 1925 several banks failed to open in a city where Mrs. Vaught lived. The other banks expected a run the next day, and so the officers of the bank in which Mrs Vaught worked as a teller had enough money on hand to pay off their depositors. The officers simply told the tellers to pay on demand. The next morning a crowd gathered in the bank and on the sidewalk outside. The length of the line made many think that the bank could not possibly pay off everyone. People began to push and then to fight for places near the tellers’ windows. The power of the panic atmosphere was such that two tellers, though they knew that the bank was quite all right and could pay all depositors, drew their own money from the bank. Mrs Vaught says that she had difficulty keeping herself from doing the same.

June 5 is World Environment Day. This makes us pay more attention to our environment and the need to protect it.
When Wang Boxuan, a Beijing high schoolboy, uses up his exercise books, he does not throw them away. Each one is stored at his school with hundreds of exercise books given by other students. Then they are sold to a Beijing paper making factory.
The paper is recycled and used again by students and teachers in the school. At the same time, the money made from the sales goes towards schools in Inner Mongolia for planting trees and grass. This place is one of the sources of the sandstorms that often attack Beijing during springtime.
Wang’s school is one of the schools in the capital that take part in the “Green Promise” —environmental protection activity. So far, nearly 210,000 students have taken part in the activity, collecting more than 87 tons of waste paper.
Students are eager to help make the capital a more pleasant place.

3.What can we infer from the third paragraph?
A. Students will have no exercise books to use in many years.
B. There will be no waste paper in many years.

Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.
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.
