People do not usually like floods but some farmers need floods when their fields are too dry.When there is a flood, the water carries mud and sand from the river bed to the field near the river. When the water goes away, the mud and sand become good soil.
People in many countries tell stories about a very big flood. The flood covered the world. Here is just one of those stories.
A long , long time ago there was a man called Noah(诺亚). He lived with his wife, his three sons and his sons’ wives. One day, Noah heard a voice. It said: “Noah, soon there will be a big flood. You must build a boat. You must put two of every animal and bird in the boat. Many, many people will die in the flood but you and your family will be all right.”
Noah and his family built a boat. They put two of every animal and bird in their boat. They put food in the boat, too. Then it started to rain. It rained for 40 days and 40 nights. The water covered the world. The hills and mountains looked like islands. Noah’s boat stopped on the top of the mountain. At last the rain stopped and the flood went away. There was a beautiful rainbow in the sky. And the animals and birds left Noah’s boat. They ran, jumped, walked and flew away to live on the mountains.
According to the story, answer the following questions:
小题1:Can floods be good for farmers?

小题2:What did Noah build to protect his family from the flood?

小题3:How long did the rain last?

小题2:He built a boat.

题目分析：本文主要讲述了一个关于洪水有时也可以给农民带来好处。并借助诺亚方舟的故事对这一问题进行详细说明，但是这个故事和前文联系不算紧密。
小题1:通过阅读第一段可知洪水可以为农民带来肥沃的泥土，故为肯定回答。
小题2:根据Noah and his family built a boat.以及上下文可知他建造一艘船。
小题3:根据It rained for 40 days and 40 nights.可知大雨下了四十个日夜。故答For 40 days and 40 nights.
点评：本文从整体可分为两部分，洪水有时也可以给农民带来好处和诺亚方舟的故事。但是这两部分联系不够紧密。各个小题解答较易，都能从短文找出适当根据。答案可以从原文总结也可以直接引用。答题时注意答案的人称、时态和数的问题，要与问题保持一致。
