每日一练:特岗教师考试专业基础每日一练(2019/10/14)【分析解答题】Now satellites 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(大气),because this is where the weather form.They send these pictures to the weather stations.So meteorologists(气象学家)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 them with earlier ones.Perhaps they may find that the clouds have changed during the last few hours.This may mean that 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 0r 48 hours.Now they can make good forecasts for three or five days.Soon,perhaps,they may be able to forecast the weather for a week or more ahead.

网考网试题解析:
31.A【解析】细节题,根据第一段的“They are in space”知道答案选A。 32.C[解析]细节题,根据第一段“because this is where the weather form”知道答案选C。 33.B[解析]根据第二段的说明我们知道,是通过拍摄的新的照片和之前拍摄的照相比较。发现天气可能发生的变化。A句意为当他们接收到卫星图片的时候,这时候还没有比较。所以没办法预报天气。B句意为在他们将新的图片和之前的比较之后,这个符合文章的意思。C句意为在他们接收到卫星图片之前,接收图片之前怎么可能预报天气呢,所以C也不正确。D句意为当他们在研究卫星图片的时候,和文章的说明不符。所以答案选B。 34.D[解析]文章最后一句说“they may be able to forecast the weather for a week or moreahead.”一个星期是七天,所以答案选D。 35.D[解析]卫星确实是用来拍摄图片的,但无论是拍摄图片,还是接收图片,最后的 目的都是为了预报天气。所以答案选D。 查看试题解析出处>>
