15.When the weather is hot,you go to a lake or an ocean.When you are near a lake or an ocean,you feel cool.Why?The sun makes the earth hot,but it can not make the water hot.Though the air over the earth becomes hot,the air over the water stays cool.The hot air over the earth goes up,then the cool air over the water moves in and takes the place of the hot air.When you are near a lake or an ocean,you feel the cool air when it moves in.You feel the wind and the wind makes you cool.Of course scientists cannot answer all of our questions.If we ask"Why is the ocean full of salt?"scientists will say that the salt comes from rocks.When a rock gets very hot or very cool,it cracks(崩裂),and rain falls into the cracks.The rain then carries the salt into the earth and the rivers.The rivers carry the salt into the ocean.But then we ask"What happens to the salt in the ocean?The ocean does not saltier every year."scientists are not sure about the answer to the question.
We know a lot about our world.But there are still many answers that we do not have,and we are curious(好奇的).

分析 当天气炎热时,你去湖边或海边,当你靠近湖或海边时,你感觉很凉爽.为什么?太阳使地球变热,但它不能让水变热.虽然地表上空的空气变热,但是水面上方的空气并不热.地表上方的热空气上升,然后水上的冷空气移动并取代地表上方的热空气.当你在湖或海洋附近,冷空气移动的时候你会感觉到它.你感觉到风,而且风使你感觉凉爽.
当然,科学家不能回答我们所有的问题.如果我们问"为什么海洋里充满了盐?"科学家会说盐来自于岩石.当岩石变得非常热或非常凉时,它就会裂开,雨水就会落入裂缝.雨水就会把盐带入地表和河流.河流携带盐进入海洋.然后我们问"海洋中的盐发生了什么?海洋不会变得更咸."科学家们不确定这个问题的答案.
关于我们的世界我们知道很多.但对许多问题我们都没有答案,我们很好奇.
解答 31.D.词义推断题.根据When you are near a lake or an ocean,you feel the cool air when it moves in.You feel the wind and the wind makes you cool.可知,当它移动的时候你会感觉到他,而再根据上一句The hot air over the earth goes up,then the cool air over the water moves in and takes the place of the hot air.地表上方的热空气上升,然后水上的冷空气移动并取代地表上方的热空气.因此这里的它,即it指代的是水面上方的冷空气,即the cool air over the water.
32.A.细节理解题.根据Of course scientists cannot answer all of our questions.可知,科学家可以解释为什么炎热的天气去湖边或海边的时候会感觉到凉爽,但是科学家并不能解释我们所有的问题,例如下面提到的海水中的盐发生了什么、海水为什么不会变得更咸?因此科学家能够解决的是What makes people feel cool near a lake or an ocean in summer.并不能解决关于海洋的所有问题.
33.D.细节理解题.根据When a rock gets very hot or very cool,it cracks(崩裂),and rain falls into the cracks.可知,当岩石太热或太凉时均会导致其崩裂,因此答案为D.
34.B.推理判断题.关于A选项的问题,The reason why people feel cool when they are near a lake or an ocean in hot weather.文中已经给出了解释"The sun makes the earth hot,but it can not make the water hot.Though the air over the earth becomes hot,the air over the water stays cool.The hot air over the earth goes up,then the cool air over the water moves in and takes the place of the hot air.When you are near a lake or an ocean,you feel the cool air when it moves in.You feel the wind and the wind makes you cool."A正确;关于The reason why the ocean doesn't get saltier every year.这个问题,文中已经指明,科学家不能给我们答案,But then we ask"What happens to the salt in the ocean?The ocean does not saltier every year."scientists are not sure about the answer to the question.,因此B错误;The reason why the water in the ocean is salty.这个问题的答案文中也已经指明,是由于岩石在过热或过冷的条件下会崩裂,雨水将盐带入河流,最终汇入海洋;The reason why rocks crack.文中也已指明原因;
35.B.文章主旨题.根据全文的内容,主要讲述的内容是关于海洋的一些知识,其中有些问题科学家能够帮我们解决,有些科学家不能解决,也就是scientists can explain many things,but not everything,科学家能给我们解释很多问题,但是并不能解决我们的所有问题.
点评 本文旨在介绍海洋相关的知识,从而引出我们迫切希望了解我们生存的环境.做题时要在理解好文意的基础上,与题目有机的结合,从文章中找到相关细节性的句子与选项细细比对,进行选择和推理判断选出符合文章内容的正确选项.做题注意灵活,有时可采用排除法或直选法确定出最终答案.
