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.

Lakes, ponds, and beaches mean summer fun and cool relaxation from hot weather. But water also can be dangerous for kids if you don't take great care. Nearly 1,000 kids die each year by drowning.
Here are some tips to keep your kids safe in the water:
At the Lake or Pond
·Don't let little kids swim alone without adult supervision— lakes or ponds may be shallow near the bank and are suddenly deep sharply further out from shore.
·Ponds and lakes may hide jagged rocks, broken glass, or rubbish.
·Make sure kids wear foot protection; even in the water, they should wear socks or water shoes.
·Watch out for weeds and grass in the water that could trap a leg or arm.
·Most boating accidents, particularly among teenagers, are related to alcohol(饮酒). Be sure teens know about the dangers of alcohol, on and off the water.
At the Beach
·Teach kids to always swim when and where a lifeguard is on duty. Unlike the calm waters of a swimming pool, the beach has special dangers like currents and tides(暗流). Check with the lifeguard when you arrive to find out about the water conditions.
·Tell kids never to stand with their back to the water because a sudden wave can easily knock a child over.
·Teach kids that if they're caught in a dangerous wave, they should swim parallel（顺行地） to the shore or should tread （踩）water and call for a lifeguard's help.
Whether at the lake or at the beach, teach your child to get out of the water during bad weather, especially lightning.
1.Which is the right behavior when swimming at the beach?
