题目内容

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 more healthy place.

56. Generally speaking, indoor air pollution may be more harmful than the air outside because ______.

A．indoor air pollution can often make people seriously ill

B．man-made building materials give off dangerous gases

C．there may be more harmful gases outside the buildings

D．the air indoors is polluted, which is very harmful

57. Some kind of indoor pollution can be found in _______.

A．every modern house B．every old house

C．all kinds of houses D．all kinds of offices

58. The indoor air pollution is caused by ______.

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

59. 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.

A round of applause, please, for the Indian man who recently sang for 80 hours straight, setting a new Guinness world record. It’s an impressive feat, to be sure, but let’s just hope he still has a voice. According to Indian newspapers, Rajesh Burbure has been told to keep silent for several days so his vocal cords (声带) can heal.

It was reported that Burbure and his family are in a celebratory mood. “It’s a proud moment for all of us,” his wife told DNAIndia.com.

I, on the other hand, am unable to share their enthusiasm. Don’t get me wrong: I hope the 35-year-old Burbure lives forever, sells a million records and becomes an international celebrity. But his record–singing for 80 hours straight–is about as meaningful as most of the other curious but crazy feats listed in the Guinness Book of World Records.

Granted , I’m not qualified to speak on the subject. I’ve got no world records to my name– and I never expect to have any. Then again, maybe I am qualified to speak for those of us who have better things to do than train for years to sing an 80-hour medley (混合曲) of pop songs.

But let’s not just pick on poor Burbure. He’s not the only person chasing meaningless accolades. The Guinness Book of World Records is full of the names of people who at one time grew the longest hair, or built the biggest bicycle, or baked the largest cheesecake.

To all of these enterprising (有进取心的) souls I ask, simply, “What was it all for?”

Congratulations! For all of your painstaking effort, you became a footnote in a thick book that no one reads, except for you and the person who will eventually surpass you–with one more hour of singing, a few more centimeters of steel or a few more pounds of cheese.

After all, records are made to be broken.

Dior was born in Normandy in 1905, and his family’s original plans for him included a career in the diplomatic service, but by the time he was twenty-three, with his parents’money, he opened a small art gallery in Paris. By 1931, the money had been used up. Dior’s friends in the art gallery, asked him to draw and he took his first step at designing and drawing. His first job was with Lucien Lelong from whom Dior learned his craft（手艺）.

In February,1947, Dior started the New Look in his first major Paris collection. He was backed by a famous textile producer, Boussac, who looked after the dollars, while Dior looked after the fashions. Dior knew nothing about cutting and sewing, but he was good at fashion design.

The New Look started an entirely different look to costume, with a tiny waist, a rounded shoulder and a shapely bust（胸围）, usually with a low-cut neckline and a long full skirt. To women who had lived through the war years, the femaleness of the New look was a great success, for people were tired of tile extremely plain, wartime restrictive fashions.

It is said that dresses by Dior were “constructed like buildings”, but young people were attracted to his design, and all over the western world, manufacturers plunged(投入) into the production of his new style. Dior’s revolutionary designs lighted up a whole cycle of fashion, rounded, gentle, feminine, a delight in elegance. A New Look House of Dior opened in 1948, followed by one in London. Considered as King of Couture（women’s clothing）for years, the Dior empire grew until it covered every country in the western world, and included furs, hosiery, jewelry, perfumes, men’s wear and on and on. More than 1,000 people worked at the Paris headquarters then.

His sudden death in 1957 when he was 53 years old did not stop the growth of the House of Dior. Even now, so many years after his death, his name is closely connected with fashion throughout the world, and indeed is one of the most recognized names in the world, His first, great New Look, with its long skirts was an expression of freedom in the late 1940s.

1. Which of the following designs is close to Dior’s?

A. B. C. D.

2.According to the passage. in Dior’s life, he did NOT___________.

A. make creative fashion designs B. work in a diplomatic service

C. 1earn craft as his first job D. open a New Look House

A. Dior and his supporter had different interests in business

B. Dior’s New Look had little influence on people then

C. Dior is only a brand of women’s fashion

D. Dior’s fashion was not accepted at first

4. What is probably the best title for the passage? .

A. The History of the New Look B. The Growth of the Dior Empire

C. An Expression of Freedom—Dior D.The Founder of the New Look-Dior

The band that wasn’t

Have you ever wanted to be part of a band as a famous singer or musician? Have you ever dreamed of playing in front of thousands of people at a concert, at which everyone is clapping and appreciating your music? Do you sing karaoke and pretend you are a famous singer like Song Zuying or Liu Huan? To be honest, a lot of people attach great importance to becoming rich and famous. 1

Many musicians meet and form a band because they like to write and play their own music. They may start as a group of high-school students, for whom practising their music in someone's house is the first step to fame. Sometimes they may play to passers-by in the street or subway so that they can earn some extra money for themselves or to pay for their instruments. 2 Of course they hope to make records in a studio and sell millions of copies to become millionaires!

3 It was called the Monkees and began as a TV show. The musicians were to play jokes on each other as well as play music, most of which was based loosely on the Beatles. The TV organizers had planned to find four musicians who could act as well as sing. They put an advertisement in a newspaper looking for rock musicians, but they could only find one who was good enough. They had to use actors for the other three members of the band.

4 So during the broadcasts they just pretended to sing. Anyhow their performances were humorous enough to be copied by other groups. They were so popular that their fans formed clubs in order to get more familiar with them. Each week on TV, the Monkees would play and sing songs written by other musicians. However, after a year or so in which they became more serious about their work, the Monkees started to play and sing their own songs like a real band. Then they produced their own records and started touring and playing their own music. 5 . The band broke up about 1970, but happily they reunited in the mid-1980s. They produced a new record in 1996, with which they celebrated their formal time as a real band.

A. In the USA they became even more popular than the Beatles and sold even more records.

B. The Monkees’ television show stayed on the air for years after the group broke up. .

C. However, there was one band that started in a different way.

D. But just how do people form a band?

E. Later they may give performances in pubs or clubs, for which they are paid in cash.

F. Most of us probably have our favorite performers, stars or bands, but many of us also want to discover new sounds and rhythms.

G. As some of these actors could not sing well enough, they had to rely on other musicians to help them.
