19.Some scientists say that animals in the ocean are increasingly threatened by noise pollution caused by human beings.It is caused mainly by industrial underwater explosions,ocean drilling,and ship engines.
Some scientists have proposed (提議) setting a noise limit of one hundred and twenty decibels (分貝) in oceans.They have observed that noises at the level can frighten and confuse whales.
A team of American and Canadian scientists discovered that loud noises could seriously injure some animals.They found that powerful underwater explosions were causing whales in the area to lose their hearing.This seriously affected the whales'ability to exchange information and find their way.Some of the whales even died.
Some researchers whose work depends on ocean sounds object to a limit of one hundred and twenty decibels.They say such a limit would mean an end to important industrial and scientific research.Scientists do not know how much and what kinds of noises are harmful to ocean animals.However,many scientists agree that noise is a greater danger than they believed.They want to prevent noises from harming creatures (生物) in the ocean.
29.Concerning the effect of noises on whales,which of the following is TRUE?B
A.They are deaf to noises.
B.Noises at a certain level may hurt them.
C.Noises could kill them.
D.Noises will cause them to lose their eyesight.
30.Some scientists think that the noise limit of one hundred and twenty decibels wouldA.
A.prevent them doing their research work
B.benefit them a lot in their research work
C.do good to their health
D.increase the industrial output
31.According to the last paragraph,what will scientists most probably do in the future?D
A.They will study the effect of different noises in the sea.
B.They will work hard to make no noise.
C.They will never do any scientific research in the sea.
D.They will protect sea animals from harmful noises.

分析 科學家認為,人類海上活動導致的噪音污染對海洋生物的健康和行為產(chǎn)生了巨大的影響,甚至威脅到了他們的生存.雖然科學家不知道什么樣的噪音對海洋生物有害,然而許多科學家懷疑噪聲的危害要遠遠大于他們想象的程度,因此他們要努力去防止噪聲對于海洋動物的危害.

解答 29--31 BAD
29.B 推理判斷題.根據(jù)第三段They found that powerful underwater explosions were causing whales in the area to lose their hearing.This seriously affected the whales'ability to exchange information and find their way可知,這些海洋噪音影響到了鯨魚的聽力和導航能力,即:一定程度的噪音可能傷害鯨魚.故選B.
30.A 細節(jié)理解題.根據(jù)四段They say such a limit would mean an end to important industrial and scientific research.可知,科學家們認為對于分貝的控制會影響一些工業(yè)和科學研究工作,所以A選項正確.
31.D 細節(jié)理解題:從最后一段的句子:They want to prevent noises from harming creatures in the ocean.可知,他們想要阻止噪音對于海洋生物的危害.故選D.

點評 高考中選用的科技文往往反映的是當今人類最先進的科技水平和最新的科研成果.我們閱讀它的過程其實就是學習科學知識,掌握科技信息的過程.然后,理解文章,分析文章,以閱讀材料所提供的科學事實為依據(jù),同時得出的結(jié)論還應(yīng)符合基本的科普常識,在細心對照基礎(chǔ)上,經(jīng)過一番分析、綜合,然后就要根據(jù)題目要求對選項作出正確判斷了,這些判斷包括選項的表達是否符合原文的意思,對概念,文句的理解是否正確,對要點歸納是否全面等,從而排除錯誤選項,選擇最合適的答案.

7.Driving Offence Points System
What is Driving  Offence Points System?
After the introduction of this system,certain traffic offences will earn the driver points besides other punishment.If a driver makes any of these offences,the points will be recorded.When the driver gets a certain number of points,he will be forbidden to drive for a certain amount of time.

14.Maybe ten-year-old Elizabeth put it best when she said to her father."But,Dad,you can't be healthy if you're dead."
Dad,in a hurry to get home before dark so he could go for a run,had forgotten to wear his safety belt--a mistake 75% of the US population make every day.The big question is why.
There have been many myths about safety belts ever since their first appearance in cars some forty years ago.The following are three of the most common.
Myth Number One:It's best to be"thrown clear"of a serious accident.
Truth:Sorry,but any accident serious enough to"throw you clear"is also going to be serious enough to give you a very bad landing.And chances are you'll have traveled through a windshield (擋風玻璃) or door to do it.Studies show that chances of dying after a car accident are twenty-five times greater in cases where people are"thrown clear."
Myth Number Two:Safety belts"trap"people in cars that are burning or sinking in water.
Truth:Sorry again,but studies show that people knocked unconscious(昏迷) due to not wearing safety belts have a greater chance of dying in these accidents.People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situations,not to be trapped in them.
Myth Number Three:Safety belts aren't needed at speeds of less than 30miles per hour.
Truth:when two cars traveling at 30mph hit each other,an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10meters.

24.The reason Father was in a hurry to get home was that heC.
A.wasn't feeling very well
B.hated to drive in the dark
C.wanted to take some exercise
D.didn't want to be caught by the police
25.According to the text,to be"thrown clear"of a serious accident is very dangerous because youB.
A.may be knocked down by other cars
B.may get seriously hurt being thrown out of the car
C.may find it impossible to get away from the seat
D.may get caught in the car door
26.Some people prefer to drive without wearing a safety belt because they believeA.
A.the belt prevents them from escaping in an accident
B.they will be unable to think clearly in an accident
C.they will be caught when help comes
D.cars catch fire easily
27.What is the advice given in the text?C
A.Never drive faster than 30miles an hour.
B.Try your best to save yourself in a car accident.
C.Never forget to wear the safety belt while driving.
D.Drive slowly while you're not wearing a safety belt.

4.I recently got pulled over for speeding not far from my new home in Virginia.I hadn't been paying attention,and I had driven a few miles an hour over the speed limit.
"Can I see your license and registration?"the police officer asked me.I pulled both out for him,and he saw my Pittsburgh address on my Pennsylvania driver's license.
"What are you doing here?"he asked."Are you with the army?"
"No,I'm not."I answered.I explained that I had just moved to Virginia,and I hadn't had time to re-register yet.
"So what brings you here?"He had asked a direct question.Without thinking very hard,I gave him a direct answer."Well,officer,"I said,"since you've asked,I have cancer.I have just months to live.We've moved down here to be close to my wife's family."
"So you've got cancer,"he said flatly.He was trying to figure me out.Was I really dying?Was I lying?He took a long look at me."You know,for a guy who has only a few months to live,you sure look good."
He was obviously thinking:"Either this guy is pulling one big fat line on me,or he's telling the truth."He was trying to question my honesty without directly calling me a liar.And so he had forced me to prove that I was being honest.
"Well,officer,I know that I look pretty healthy.I look great on the outside,but the tumors(腫瘤)are on the inside."And then,I don't know what possessed me,but I just did it.I pulled up my shirt,showing the operational scars.
He looked at my scars.He looked in my eyes.He now knew he was talking to a dying man.Well,he wasn't taking this any further.He handed me back my license."Do me a favor."he said,"Slow down from now on."
The awful truth had set me free.As he went back to his police car,I had a realization.I had been one of those gorgeous blondes (金發(fā)美女) who could bat her eyelashes and get out of tickets.I drove home under the speed limit,and I was smiling like a beauty queen.
24.The author was stopped by the police officer becauseA.
A.he drove too fast
B.he forgot to re-register
C.he was seriously ill
D.he didn't have a license
25.The author moved to Virginia probably becauseC.
A.he was unhappy
B.Virginia had better hospitals
C.he could spend more time with families
D.he served in the army there
26.On hearing about the author's cancer,the police officerB.
A.said it was an excuse 
B.doubted his honesty
C.showed sympathy for him
D.a(chǎn)sked him to show his scars
27.It can be inferred from the passage that the author wasD.
