A sandstorm hit Gansu Province, Inner Mongolia Autonomous Region (内蒙古自治区) and Beijing on Sunday, reducing visibility (能见度) to less than 100 meters in affected areas. When visibility drops to less than 1 kilometer, it is called a sandstorm. The sandstorm in Minqin blew up dust in neighboring towns, such as Baiyin, Wuwei, and Jinchang.

Dust winds also swept into Beijing at more than 20 meters per second. Dust first reached the capital’s suburbs at 7 a.m., downtown areas at 9 a.m. The Palace Museum in central Beijing was covered in thick, brown-yellow dust at noon. The winds, which died down during the night, brought the temperature down to 8℃ below zero and many flights put off their planned time from the city’s airport.

Although the Chinese Central Weather had forecast the sandstorm on Tuesday and warned citizens to prepare for it, many people were shocked by the yellow sky. Wang Hongsheng, a senior citizen living in Beijing for more than 60 years, said such weather had seldom been seen in recent years. In the northwestern part of the city, the sky was darkened by the sand, forcing cars and shops to turn on their lights.

It is quite rare for sandstorms, which are frequent between March and June, to happen in winter, when the earth is frozen. The sandstorms in Gansu and Inner Mongolia do not necessarily mean there will be more of them in the spring than last year, but Beijing is taking it very seriously. It is reported that Beijing will spend 6 billion yuan in preventing sandstorms in the capital and has already set up a special team to make sure what causes them.

请认真阅读下面短文，从短文后各题所给的A、B、C、D四个选项中，选出最佳选项。
Strong winds, sand in the air, poor visibility (能见度), we all know the characteristics of a sandstorm. But what else do you know about them?
Did you know, for example, that the first sandstorm of 2009 hit north China’s Inner Mongolia autonomous region late February?
Sandstorms are today a feature of life in northern China because of desertification (沙漠化) and the retreat (退化) of the northern grasslands. They usually occur between February and May.
Fortunately, sandstorms this year should be fewer than in past years in north China, according to the National Meteorological Center (中央气象台).
And the chances of sandstorms hitting Beijing are small, because recent rain has stopped drought and reduced dry dirt and dust. Tree planting, and other measures taken by the government, has also helped decrease the chance of sandstorms in the city.
Sandstorms can be dangerous. However, there are measures you can take to protect yourself from harm.
﹡Wear a mask. Cover your nose and mouth with a mask that can keep out sand, or use a damp handkerchief.
﹡If you are driving and the storm is at a distance, it may be possible to outrun (超过) it. If it looks like you will be caught in the storm, stop and wait it out.
﹡Take a cover. If there is no shelter, then lie down. Keep eyes, nose and mouth covered. Cover your head with your arms or a backpack to protect yourself against flying objects.
If you are caught in a desert sandstorm, take the following actions.
﹡Mark your direction before lying down. It is easy to get lost in a desert.
﹡Keep plenty of water at hand. If you get lost, you need water to survive until you find your way or help arrives.
﹡Stay together if traveling in a group. Lock arms if caught in a sandstorm. The most useful measure would actually be to make sandstorms disappear forever. To make this goal come true, people should plant trees, and stop desertification.
Today, the straight-line distance between Tiananmen Square and a desert called Tianmo in Hebei province is only about 80km. If desertification is not stopped, environmental protection experts say, it will probably not be long before Beijingers can catch a camel to work.
56.According to the passage, which of the following statements is true?
A. So far in 2009 no sandstorm has happened.
B. Sandstorms usually happen in spring.
C. Sandstorms are a feature of life in China.
D. In sandstorms in cities, what you need to protect yourself from is just the sand in the air.
57.Which may not be the right action to take to protect yourself from harm in a sandstorm?
A. Finding a shelter.
B. Covering your head with a bag.
C. Lying down.
D. When driving, speed up and rush through the sandstorm.
58.What can we infer from the passage ?
A. North China has been suffering from sandstorms for several years.
B. The distance between Beijing and the desert has made the chances of sandstorms hitting Beijing small this year.
C. Planting trees can help make sandstorms disappear.
D. It is more dangerous to be caught in sandstorms in cities because there are more flying objects.
59.What’s the best title of the passage?
A. The realities of sandstorm                          B. The cause of sandstorm.
C. The influences of sandstorm                       D. The future of sandstorm.

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.

1.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.

2.From the second paragraph, we can learn that at present _______.

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

3.The author will most probably agree that ________.

A．there will soon be no sandstorms in the USA

B．humans haven’t thought of any way to deal with sandstorms

C．death caused by sandstorms is increasing all the time

Sandstorms hit northwestern China's Gansu Province and North China's Inner Mongolia Autonomous Region on the first day this year. According to Sun Landong， a meteorologist with the Lanzhou Meteorology Observatory，visibility was less than 100 meters in Minqin， a Gansu county near Inner Mongolia， because of sand. When visibility drops to less than 1 kilometer，it is called a sandstorm. The sandstorm in Minqin blew up dust in neighboring towns， such as Baiyin， Wuwei， Jinchang and Lanzhou， the capital city of Gansu Province. Dust-laden winds also swept into Beijing. Brought by northwesterly blowing at more than 20 meters per second，dust first reached the capital's suburbs at 7 a. m，downtown areas at 9 a. m. The winds，which died down during the night，brought the temperature down to as low as 80C below zero and many flights put off their planned time from the city's airport.

It is quite rare for sandstorms，which are frequent between March and June，to happen in winter，when the earth is frozen. The sandstorms in Gansu and Inner Mongolia do not necessarily mean there will be more of them in the spring than last year，when they were serious，but Beijing is taking it very seriously. It is reported that Beijing will spend 6 billion yuan ( US 725 million) in preventing sandstorms in the capital and has already set up a spe­cial team to make sure what causes them.
