Do you think stones (石头) can move by themselves? There are some famous moving stones in Death Valley, the US. Many of the stones are small but a few of them are very big. Some of the big stones are as big as a man. The biggest stone weighs about 350 kg. The stones only move at night. Nobody has ever seen them moving, but now scientists (科学家) know the answer to the question. The answer is the wind. When the wind comes from the west, the stones move to the east. When the wind is from the south, they always move to the north. But how can the wind move a very heavy stone?
Death Valley is one of the hottest place in the world, but it can be very cold at night. Sometimes, there are even bad storms (暴风雨) at night. Rain falls, and the wind is strong and cold. The water on the ground turns into ice easily. Then the strong wind can move the stones along the ground. In the morning, the sun comes up and dries (使……变干) the ground. So people can find them move from one place to another in the daytime.

Education plays an important part in modern life. However, in some poor areas, many children can't afford the expenses of schooling (付学费) and are forced (被迫) to leave school. At the same time, our country is not able to invest (投资) too much in it. Under this condition, the Project Hope is necessary to our country. Firstly, it will create conditions (创造条件) for the children to go back to school. Secondly, it can make more people educated. So it can lead to the improvement of people's standards (标准) of life.
In my opinion, the Project Hope is of great importance to our country. I hope that with its help more and more children can get the opportunity (机会) to be educated.
so much, by bus, all the time, a bit, the same as |
I think it's to travel by car.
New York is a very large city with more than eight million people. How do so many people move on their way to work or school? In New York you can travel by subway, bus, taxi and private car.
The subway runs on the railroad lines under the city. Travelling by subway is the fastest way to get around the city. The second way to travel around the city is by public bus. It is a slower way to travel. This is because the traffic is very heavy.
You can also travel around the city by taxi. This is very expensive, but the taxi will take you to every place you want to go. If the traffic is heavy, the taxi will be slow too.
During the mornings and afternoons, there is the "rush hour". This is the time when the traffic is very heavy with people going to and from work. The last way to get around New York is using your private car. It is inconvenient（不方便的）because you will perhaps be driving during the "rush hour". The best time to travel around the city is from 9 am to 4 pm, because it isn't the "rush hour".
Nick is a 14-year-old schoolboy. His life is full of exams and studies from Monday Friday every week. He has little free time. He thinks playing computer games is the best way (make) himself relaxed. When he has free time, he always sits in front of the computer. Sometimes he doesn't eat or drink for several (hour) .

Then he was ill. He had to see a doctor. The doctor told him he should do more exercise and outdoor activities to make him have a (health) body.
