A sandstorm, also known as a dust storm, is exactly what it sounds like. A very strong windstorm especially in the desert carries clouds of sand or dust that greatly reduces visibility. This wind is usually caused by convection currents (对流气流), which are created by intense heating of the ground, and is usually strong enough to move entire sand dunes. Air is unstable when heated, and this instability in the air will cause higher winds to mix with winds in the lower atmosphere, producing strong surface winds.
Sandstorms can disturb people’s travel, and can sometimes destroy whole roads, and dry flat areas. Similar dust storms can be found on the planet Mars, and are thought to be seasonal. Today, the destruction of forests and too much farming of farmland can lead to sandstorms. Too much use of water resources can also cause sandstorms.
In the United States of America, sandstorms are rare because of the lack of large deserts and more importantly the development of proper agricultural techniques. The last recorded destructive sandstorm in American history was the Dust Bowl, which occurred on July 16, 1971 and was widely recorded by meteorologists (气象学家).
To protect themselves from sandstorms, some people wear protective suits. Special equipment can be fixed in some cars to prevent sand from getting into the engine. Sandstorms can cause coughs, and the sand and dust has also been known to carry “infectious diseases”. Sand particles, unlike dust ones, will block air passages, and cause a person who breathes them in to choke. Dust particles may cause an allergic (过敏的) reaction.Which of the following plays the first part in forming sandstorms?
| A．The instability of the sand. |
| B．The instability of the wind. |
| C．The intense heating of the ground. |
| D．The speed of the wind. |

| A．sandstorms are more often seen on Mars than on Earth |
| B．sandstorms have led to the lack of clean water resources |
| C．farming brings more harm than benefits to humans |
| D．human activities are a major cause of sandstorms |
The author will most probably agree that ________.

| B．humans haven’t thought of any way to deal with sandstorms |
| C．death caused by sandstorms is increasing all the time |
| D．humans should make more efforts to stop soil turning into desert |

When a group of children politely stop a conversation with you, saying: “We have to go to work now,” you’re left feeling surprised and certainly uneasy. After all, this is the 1990s and the idea of children working is just unthinkable. That is, until you are told that they are all pupils of stage schools, and that the “work” they go off to is to go on the stage in a theatre.
Stage schools often act as agencies（代理机构）to supply children for stage and television work. More worthy of the name “stage school” are those few places where children attend full time, with a training for the theatre and a general education.
A visit to such schools will leave you in no doubt that the children enjoy themselves. After all, what lively children wouldn’t settle for spending only half the day doing ordinary school work, and acting, singing or dancing their way through the other half of the day?
Then of course there are times for the children to make a name and make a little money in some big shows. Some stage schools give their children too much professional work at such a young age. But the law is very tight on the amount they can do. Those under 13 are limited to 40 days in the year; those over 13 to 80 days.
The schools themselves admit that not all children will be successful in the profession for which they are being trained. So what happens to those who don’t make it? While all the leading schools say they place great importance on children getting good study results, the facts seem to suggest this is not always the case.
People would stop feeling uneasy when realizing that the children they’re talking to________.
| A．attend a stage school | B．are going to the theatre |
C．have got some work to do | D．love singing and dancing |
In the writer’s opinion, a good stage school should ________.
| A．produce star performers |
B．help pupils improve their study skills |
C．train pupils in language and performing arts |
D．provide a general education and stage training. |
“Professional work” as used in the text means ________.
| A．ordinary school work | B．money-making performances |
C．stage training at school | D．acting, singing or dancing after class |
Which of the following best describes how the writer feels about stage schools?
| A．He thinks highly of what they have to offer. |
B．He favours an early start in the training of performing arts. |
C．He feels uncomfortable about children putting on night shows. |
D．He doubts the standard of ordinary education they have reached. |
Maybe ten-year-old Elizabeth put it best when she said to her father, "But, Dad, you can't be healthy if you're dead."
Dad, in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety belt-- a mistake 75% of US population make every day. The big question is why.
There have been many myths about safety belt ever since their first appearance in cars some forty years ago. The following are three of the most common.
Myth the Number One: It's best to be "thrown clear" of a serious accident.
Truth: Sorry, but any accident serious enough to "throw you clear" is able going to be serious enough to give you a very bad landing. And chances are you'll have traveled through a windshield (挡风玻璃)or door to do it. Studies show that chances of dying after a car accident are twenty-five times in cases where people are "thrown clear".
Myth Number Two: Safety-bets "trap" people in cars that are burning or sinking in water.
Truth: Sorry again, but studies show that people knocked unconscious (昏迷) due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situation, not to be trapped in them.
Myth Number Three: Safety belts aren't needed at speeds of less than 30 miles per hour (mph).
Truth: When two cars traveling at 30 mph hit each other, an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 metres. Why did Elizabeth say to her father, "But, Dad, you can't be healthy if you're dead"?
| A．He was driving at great speed. |
| B．He was running across the street. |

| A．may be knocked down by other cars. |
| B．may get serious hurt thrown out of the car |
| C．may find it impossible to get away from the seat |
| D．may get caught in the car door |

| A．the belt prevents them from escaping in an accident |
| B．they will be unable to think clearly in an accident |

Today, roller skating is easy and fun. But a long time ago, it wasn't easy at all. Before 1750, the idea of skating didn't exist. That changed because of a man named Joseph Merlin.
