文章大意:本文是一篇说明文。一项科学研究表明烟花燃烧释放出的金属元素会造成空气污染,也会损害人类和动物的健康,同时还存在其他潜在危害。

1 . A new study suggests some of America’s favorite Independence Day fireworks can give out lead and copper (铜), which are used to give fireworks their vivid colors, and also damage human cells and animal lungs.

Led by researchers at NYU, the study showed poisonous levels of lead in the fireworks. Experiments showed that lung exposure to particle emissions (颗粒排放物) from five types of fireworks significantly increased oxidation (氧化), a chemical process in the body that can damage or even kill cells.

The researchers say the new study is believed to be the first to examine the effects of firework exposure in human cells and living animals, and to test for particles of common firework metals thrown into the atmosphere.

“While many are careful to protect themselves from injury from explosions, our results suggest that inhaling firework smoke may cause, longer-term physical damage, a risk that has been largely ignored,” says study senior author Terry Gordon, a professor in the Department of Environmental Medicine.

Gordon and his team also analyzed 14 air quality samples taken at dozens of sites across the US throughout each year. They found that levels of poisonous metals were higher in samples taken on Independence Day and New Year’s Eve celebrations than at any other time of the year. Along with lead, copper and other poisonous metals are commonly found in fireworks. “Our research shows that although we are only exposed to these poisonous substances for a short time each year, they are much more poisonous than the pollutants we breathe every day,” says Gordon.

Gordon cautions (警告) that the current investigation is the first step, only addressing the potential effects of one-time exposure to the firework metals. He says repeated exposure is likely a larger concern. Nevertheless, he is planning to share his findings with local health officials, firework producers, the Environmental Protection Agent, and other regulatory agents to alert them to the potential for harm.

1. Why do some fireworks harm our health?
A.They are oxidized in the air.
B.They can give out harmful metals.
C.They are exposed to particle emissions.
D.They can melt chemical substances in the body.
2. What does the underlined word “inhaling” in paragraph 4 mean?
A.Letting out.B.Working out.
C.Taking in.D.Blowing off.
3. What can we infer from Gordon’s research findings?
A.Fireworks are the main cause of air pollution.
B.Air quality on New Year’s Eve is above normal.
C.People breathe in poisonous air for a short time daily.
D.Air pollution on Independence Day is worse than usual.
4. What does Gordon intend to do with fireworks-related persons?
A.Remind them not to set off fireworks.
B.Caution them against producing metals.
C.Alert them to the harm of the experiment.
D.Warn them of the possible dangers of fireworks.

6 . Charlie is a teacher and his wife, Maria is an artist. The night before last, just before the longest day of the year, Charlie was sitting in a deckchair enjoying the warm summer air when Maria touched his shoulder and he could tell immediately she was a little worried about something. He asked her what the matter was and she replied that there was a strange thing on the jacket that was hanging in the bedroom. They had both lived in the West Indies (西印度群岛) and had seen a lot of strange creatures in their house before. But now they were living in England and so Charlie just laughed and said he would have a look at the “thing”.

He walked to the bedroom. He saw a jacket hanging in the bedroom and went up to it to have a closer look at the “thing”. The moment he touched it, the thing sprang into life. Now Charlie experiences fear like the rest of us but when this creature opened its wings, he jumped out of his skin and ran screaming from the room like a small child doing about 100 miles an hour.

For a moment the next-door neighbours thought that Charlie was murdering his wife because of the noise they could hear. In fact, it was a bat that frightened Charlie.

Eventually Charlie managed to trap the bat in a box and took it to the garden to let the bat fly. Maria, who had been playing the guitar while Charlie was upstairs, asked Charlie if he had found out what the thing was. “Oh, nothing to worry about”, he said casually hoping that the terror could not be seen in his eyes, “it was just a bat.”

1. Why was Maria a little worried one night?
A.Because she couldn't find her guitar.B.Because she saw something strange.
C.Because it was too hot for her.D.Because she had quarreled with her husband.
2. The underlined part “jumped out of his skin” in the second paragraph probably means ____.
A.stood upB.was very frightened
C.threw off his clothesD.was very excited
3. What happened to the bat?
A.It was killed by Charlie.B.It was badly wounded.
C.It was set free by Charlie.D.It was kept as a pet.
4. It can be inferred that ________.

B.the neighbours would report to the police about Charlie murdering the bat
C.the bat wouldn't come to Charlie's room again because it was frightened
