【推荐1】A sandstorm is a kind of strong wind that blows over the desert. It raises sand and dust into the air and makes it difficult to see the sun and it reduces visibility (能见度) of most to zero. It is also known as a dust storm. Some storms are usually the result of convection currents (对流气流) caused by the strong heating of the ground. Then wind is usually strong enough to move a small hill of sand. It can make travel very difficult and can even destroy roads in flat dry areas such as those in the United States.

The Simoom is the strong hot wind that comes across the Sahara and Arabian Desert. This wind is the reason for much of the dust in the air over Europe. Evidence of the dust from Simoom wind has also been found at the bottom of the sea at a long distance from the shore. Alasksi is the strongest sandstorm. It can destroy all the things in his way. It is very dangerous. It has killed more than one hundred people in the area. The Haboob is a sandstorm that often happens in the area of Sudan around Khartoum.

Sandstorms, the height as 50000ft (1,525m), also happened, although not often in the United States. It is stronger than the Simoom. One that appeared near Tucson, Arizona, on July 16, 1971, was widely proved by meteorologists (天文学家).

【推荐1】Last Sunday, it was sunny. My mother took me and my sister Helen to visit the Hong Kong Museum of History. The museum is in Kowloon Park(九龙公园). First we went to the swimming pool in the park. Helen and I swam for two hours in the pool.

We got to the museum at eleven o'clock. We saw an old store, a village house, an old boat and many other old things. We learned about what Hong Kong was like 100 years ago. In the past, Hong Kong was a small fishing village (渔村). Most people were fishermen.

Helen and I took some notes (笔记) about the history of Hong Kong. We also took some photos of the old things. We left the museum at two o'clock in the afternoon.

【推荐2】Few of us have heard of Nils Bohlin, but whenever we take a car journey his invention makes us safer. Found in almost every modern car, the three-point seat belt reduces our chances of death or injury by at least 50%. While feeling thankful to his engineer from Volvo, you may also wonder how he came up with such a great idea.

Having worked as a plane designer before, Nils knew clearly that the pilots were willing to put on anything to keep them safe in an accident, but to his surprise, most people in the cars just didn’t want to be uncomfortable for even a minute. To improve the safety for people in the cars, he decided to find a perfect system which should be simple, effective and convenient. In the end, he invented the three-point seat belt, which has been considered as one of the greatest inventions in history.

Seat belts prevent people in the cars from serious injury in five ways.

Keep people inside. People who are thrown out from a car are four times more likely to be killed than those who stay inside.

Protect the strongest parts of the body. Seat belts are designed to fix your body at its strongest parts. For an older child and adult, these parts are the hips(臀部)and shoulders.

Spread out the force in an accident Seat belts spread the force of the accident over a wide area of the body. By putting less stress on one area, they can help you avoid serious injury.

Help the body to slow down. A quick speed causes injury. With the help of the seat belts, your body can have more time to slow down in an accident.

Protect your brain and spinal cord(脊柱). These two key parts injuries may be hard to see immediately, but they can cause death. Therefore, it’s of great importance to protect these parts.

It takes only a few seconds to buckle up once you get in the car, but this simple action could save your life.
