10.Why do people cry?Scientists say the body produces(產(chǎn)生)tears because it needs them.One kind of tears(眼淚)is for the eye,the other is for the heart.They both work as cleaners.If something else like dust(灰塵)gets into your eye,tears also come into the eye to clean it out.If you are hurt by something,your strong feelings produce some poisonous chemicals(毒素)in your body,and at the same time,tears come out with them.If tears don't help clean out these poisonous chemicals,they will do harm to(傷害)the heart.
In the United States men have heart problems more often than women do.Doctors say heart problems have something to do with the pressures(壓力)of living and working now.Perhaps men have more of these illnesses because they do not cry enough.They need to cry more.
In fact,you can find many ways of reducing(減少)the pressures to keep fit.Crying is a natural(自然)and physical(生理)one.
43.How many kinds of tears does the body usually produce?
Two/2.
44.What do tears do when dust gets into your eyes?
Tears also come into the eye to clean it out.
45.Will you cry if you fail in the exam?Why or why not?
Yes.Because I am sad..

分析 本文主要講述了人體會(huì)產(chǎn)生兩種眼淚,一種是為了眼睛,另一種是為了心臟.并分別敘述了這兩種眼淚如何對(duì)人體產(chǎn)生作用的.

解答 43.Two/2.細(xì)節(jié)理解題.根據(jù)One kind of tears(眼淚)is for the eye,the other is for the heart.一種是為了眼睛,另一種是為了心臟.可知身體產(chǎn)生兩種眼淚,故答案為Two/2
44.Tears also come into the eye to clean it out.細(xì)節(jié)理解題.根據(jù)If something else like dust(灰塵)gets into your eye,tears also come into the eye to clean it out如果像灰塵一樣的東西進(jìn)入眼睛,眼淚也會(huì)進(jìn)入眼睛來清潔它.可知介紹了眼淚可以清潔眼睛,故答案為Tears also come into the eye to clean it out.
45.Yes.Because I am sad.細(xì)節(jié)理解題.這是一個(gè)開放性的問題,只要合情理都可以.注意一般疑問句用yes,No來回答.故答案為Yes.Because I am sad.

點(diǎn)評(píng) 主要是根據(jù)前提問題來做出相應(yīng)的要求內(nèi)的答案,題型比較靈活但是考查了學(xué)生多方面的知識(shí)和技能,要做好這類題,就要注意平時(shí)知識(shí)的積累,包括單詞、詞組、句型等.
