10.No one is glad to hear that his body has to be cut open by a surgeon(外科醫(yī)生) and part of it is taken out.Today,however,we needn't worry about feeling pain during the operation.The sick person falls into a kind of sleep,and when he wakes,the operation is finished.But these happy conditions are fairly new.It is not many years since a man who had to have an operation felt all its pain.
Long ago,operations had usually to be done while the sick man could feel everything.The sick man had to be held down on a table by force while the doctors did their best for him.He could feel all the pain if his leg or arm was being cut off,and his fearful cries filled the room and the hearts of those who watched.
Soon after 1770,Josept Priestley discovered a gas which is now called"laughing gas".Laughing gas became known in America.Young men and women went to parties to try it.Most of them spent their time laughing,but one man at a party,Horace Wells,noticed that people didn't seem to feel pain when they were using this gas.He decided to make an experiment on himself.He asked a friend to help him.
Wells took some of the gas,and his friend pulled out one of Well's teeth.Wells felt no pain at all.As he didn't know enough about laughing gas,he gave a man less gas than he should have.The man cried out with pain when his tooth was being pulled out.
Wells tried again,but this time he gave too much of the gas,and the man died.Wells never forgot this terrible event.

分析 文章大意:
文章那個主要介紹的是有關(guān)做手術(shù)是否麻醉的問題.很久之前,并沒有麻醉劑可以使用,在手術(shù)過程中人們會很痛苦.后來一個人發(fā)現(xiàn)了笑氣可以緩解手術(shù)過程中人們的疼痛感,但是用的太少的話沒有效果,用得太多又會致死.
解答 21.B,細(xì)節(jié)理解題,文中提到"It is not many years since a man who had to have an operation felt all its pain"不久之前,人們在手術(shù)之前還會全程感受到疼痛,由此確定選擇B.
22.C,細(xì)節(jié)理解題,文中提到"Long ago,operations had usually to be done while the sick man could feel everything"很久之前,人們在做手術(shù)的時候會感受到所有的疼痛,由此確定選擇C.
23.B,細(xì)節(jié)理解題,文中提到"people didn't seem to feel pain when they were using this gas"當(dāng)用笑氣的時候,人們不會感受到疼痛,由此確定選擇B.
24.C,細(xì)節(jié)理解題,文中提到",he gave a man less gas than he should have.The man cried out with pain when his tooth was being pulled out"用少了笑氣之后,在手術(shù)中途就會感覺到疼痛,由此確定選擇C.
25.B,細(xì)節(jié)理解題,文中提到"his time he gave too much of the gas,and the man died"當(dāng)笑氣用多了的時候,人就會死亡,由此確定選擇B.
點評 對于閱讀表達(dá)題,一定要記得首先通讀全文,了解文章大意,然后再根據(jù)文章關(guān)鍵詞,關(guān)鍵句,掌握細(xì)節(jié)問題,并進(jìn)行推理判斷,再去回答具體的問題.
