16.Generally speaking,kids are curious about the world around them.For instance,they want to know how their hearts beat.They want to know why the ocean water tastes salty.As children grow up,they become curious about different kinds of things.When they are babies,they are interested in the parts of their bodies and in the smiles of their mothers.They become interested in the physical world around them:the plants,the animals,and the sky.Later,they become interested in the things that people have made:wheels,bicycles,cars.And when they are adults,their curiosity continues.Sometimes this curiosity leads to a career in science.
Scientists spend their lives trying to find out about the world.Those who work with the earth sciences study the earth,the oceans,and the skies.Other scientists who study living things work with the biological sciences.A third group of scientists study the physical sciences,e.g.physics and chemistry.
These scientists have already discovered a lot about our world.For example,they tell us why your heart beats fast when you run.They say that when you are quiet,your heart normally beats sixty-five or seventy-five times a minute.Your heart is a pump (泵) that pumps blood to all parts of the body.The blood carries oxygen and nutrition.When you run,your muscles work very hard and use the nutrition that the blood carries to them.The muscles need oxygen,too.So your brain sends a signal to the heart.The signal means that the muscles need more nutrition and oxygen.Then the heart beats fast and sends blood quickly to the muscles.It may beat 90to 140times a minute.
Of course,scientists cannot answer all of our questions.If we ask,"Why does the ocean water taste salty"scientists will say that the salt comes from rocks.When a rock gets very hot or very cold,it cracks.Rain falls into 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 saltier 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.

点评 阅读理解是考查语篇理解能力.常考的题型有:推理判断题;主旨大意题;细节理解题;猜测词意题.近几年又出现了两种新的考查方式:写作态度判断题和文章结构题.解题时,在读懂文章的基础上,还有特别注意掌握题型的特征,尤其是细节题和推断题不可混淆:细节题是文章信息的再现;推断题是文章信息的提取.本题是广告类文章,考查主要是以细节题为主,细节题要注意常用的出题陷阱有:夸大,缩小,张冠李戴,偷梁换柱,无中生有等,做题时要看清看准.
