題目列表(包括答案和解析)
Now satellites(衛(wèi)星)are helping to forecast the weather. They are in space and they can reach any part of the world. The satellites take pictures of the atmosphere(大氣), because this is where the weather forms(形成). They send these pictures to the weather station. So meteorologists(氣象專家)can see the weather of any part of the world. From the pictures, the scientists can often say how the weather will change.
Today, nearly five hundred weather stations in sixty countries receive satellite pictures. When they receive new pictures, the meteorologists compare(比較)them with earlier ones. Perhaps they may find that the clouds have changed during the last few hours .This may mean the weather on the ground may soon change, too. In their next weather forecast, the meteorologists can say this.
So the weather satellites are a great help to the meteorologists. Before satellites were invented, the scientists could forecast the weather for about 24 or 48 hours. Now they can make good forecasts for 3 or 5 days. Soon, perhaps , they may forecast the weather for a week or more ahead(提前)

Satellites Forecast the WeatherNow satellites are helping to forecast (預(yù)報(bào)) the weather. They are in space, and they can reach any part of the world. The satellites take pictures of the atmosphere (大氣), because this is where the weather forms (形成). They send these pictures to the weather station.

本文采取書信形式,一位愛擔(dān)憂的老祖父給編輯部寫了一封信,內(nèi)容告誡年輕女孩兒,不要在街上亂搭不相識(shí)人的車游玩,這樣做即危險(xiǎn),也容易造成交通事故,很有教育意義.
Dear editor(編輯),
Can't your newspaper do something about the custom(習(xí)慣) of hitchhiking?
A short time ago, on a car travel I counted at least 50 people standing beside the road, asking for rides. Many of them were young women.
Don't they understand how dangerous it is to get into the car driven by a stranger? How much do they know about the driver? Is he a good driver or not? Nothing!
Many of these young hitchhikers may come from good families. Don't their parents teach them anything about the world? I always taught my children not to talk to strangers. I never let them take rides from people they didn't know.
Isn't there enough crime(犯罪) today without asking for trouble by hitchhiking? On the other hand, hitchhiking may bring some traffic trouble.
Don't you think what I said is true?
A Worried Grandfather
