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 cannot make the water very hot. Although 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 cold, it cracks (裂开). Rain falls into the cracks. The rain then carries the salt into the earth and into 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 get more salty every year." Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.
选项
A、Scientists can explain many things, but not everything.
B、The sun cannot make the water very hot.
C、Scientists know everything.
D、You feel cool when you are near a lake or an ocean.
答案
A
解析
这篇文章主题就是列举一些问题,说明科学家还不能够完全回答这些问题,这个世界还有很多未知的东西。第二段开头也提到,Of course,scientists cannot answer all of our questions。所以答案是A。
