3．Somewhere on the other side of the world，a small group of workers is busy with a life-or-death struggle．This battle isn't about self-protection，as admirable as that might be． By slaying to face the radiation and Fire at Japan's Fukushima Daiichi Nuclear Power Station following the earthquake and then tsunami（海嘯）in Japan，the 50 or so workers may have already shortened their life．They knew that would happen．
And yet they stay，working in near-total darkness，pumping seawater onto exposed nuclear fuel in hopes that they can prevent thousands of tons of radioactive material going into the air，and protect the health of millions of people．
Their task sounds like something out of a sci-fi thriller．They worked on the equipment in the complete darkness only by their flashlights，listening for explosions．They carry heavy oxygen tanks on their backs．They wear white，full-body jump suits to protect their bodies．Like Oscar said in"Armageddon"："Scariest environment imaginable．That's all you have to say．"
According to news reports，some of the 50 workers volunteered to remain behind to take charge of the fire pumps with which they're spraying seawater on the exposed fuel． It's part of the job，part of the training，"an American nuclear power plant operator said．"Nobody makes a secret of the possible dangers at a place like this．If there's a problem，you don't call somebody in to fix it．It's our problem．We're the only ones who can fix it．That's just what we do．"
I don't know about you，but I've never really thought of nuclear power plant workers as"guardians at the gate"-those whose jobs may at any time place them in a position to protect us，perhaps at the risk of their own lives．
These are obviously guardians at the gate．In every case they're trained to respond to unknown possibilities．For them，it isn't a matter of courage-it's standard operating procedure．
61．What do we know from the text？C
A．The rescue work was admirable．
B．The accident was successfully handled．
C．The workers faced a life danger．
D．The earthquake was the main reason．
62．The third paragraph is mainly aboutB

A．were ordered by the government                          
B．were requested by the world
C．left behind against their own will                      
D．were performing their duties

A．the 50 workers                      
B．the readers

解答 CBDAB
61．C細(xì)節(jié)理解題．根據(jù)第一段的內(nèi)容可知，由于地震和海嘯的雙重作用導(dǎo)致了這次事故，之后，50名工人冒著生命危險(xiǎn)搶修核電站，處理核事故．故選C．
62．B段落大意題．根據(jù)第三段主要描述了這些工人當(dāng)時(shí)的工作環(huán)境是多么的艱難和惡劣，文章引用Oscar話語："Scariest environment imaginable．That's all you have to say．"也是為了說明其工作環(huán)境的惡劣性．故選B．
63．D作者觀點(diǎn)題．根據(jù)第四段some of the 50 workers volunteered to remain behind to take charge of the fire pumps with which they're spraying seawater on the exposed fuel． It's part of the job，part of the training，可知這些工人是自愿的；而根據(jù)最后一段，這些工人不僅表現(xiàn)出他們的勇敢，同時(shí)這也是他們的職責(zé)．故選D．
64．A詞意判斷題．根據(jù)第五段I don't know about you，but I've never really thought of nuclear power plant workers as"guardians at the gate"可知"I"指作者，而此處的"you"應(yīng)該是指這50名工人．故選A．
65．B標(biāo)題概括題．本文主要是介紹了日本核電站事故后，在面臨生命危險(xiǎn)的時(shí)刻，仍有50名核電站工人堅(jiān)守崗位，努力消除故障，以防核電站進(jìn)一步的受到破壞．本文的中心是高度贊揚(yáng)了這50名工人．故選B．

11．How was it that an American ship came to be sunk by American mines in a port held by American forces？
Built in1931，the luxury liner SS President Coolidge was a 10-year veteran（退伍軍人） of the Pacific before she was pressed into service by the military and converted to carry troops．
On October 26，1942，towards the end of her first year of World War II service，the Coolidge hit an American mine in the east entrance of the Segond Channel on Espiritu Santo，one of the islands of the New Herbrides（now Vanuatu），and sank in 36meters of water．
Though all but two of the 5000officers and men aboard were saved，the loss of the ship was a military scandal．She had escaped the Japanese during the worst part of the war in the Pacific，only to be lost because of a series of disastrous American mistakes．
The master of the Coolidge，Henry Nelson，claimed he hadn't been warned that the harbor was mined．Worse，in terms of wartime security，neither of the two US destroyers the Coolidge had encountered had challenged her．Nor had they relayed the vital information about the mines．"The first warning was from a signal station further in the harbor telling me to stop，that we were approaching danger，"he wrote．
‘I，in turn，stopped the engines and backed the engines，but with the speed we were moving，we still went too far and we struck two mines．I immediately，with the speed we had left，headed the ship to the beach，and ordered"abandon ship"，which was done and completed in 45minutes．'‘No one mentioned to me，no one informed me，that there was a mine field in Espiritu Santo．Had there been some knowledge of mines，I never would have approached anywhere visible．'
Captain Nelson was exonerated（免罪） by a court of inquiry but those responsible did not escape blame．The port director's office at Noumea and the inefficiency of an experienced commanding officer of a navy patrol（巡邏隊(duì)） and pilot boat were blamed．
Today，the Coolidge is one of the world's best wreck dives．Much of her original luxury decoration remains，including The Lady，perhaps the most photographed underwater icon in the world．Military equipment she was transporting can also still be seen．

（Note：Answer the questions or complete the statements in NO MORE THAN TEN WORDS．）

78．The ship was"pressed into service by the military"suggests that it wasforced into becoming a military ship/pressed into service by the military．．
79．What caused the sinking of the ship？American mines that navy patrol failed to inform the captain about
80．Why did the ship still hit the mines after the captain stopped the engines？Because the speed of the ship made it impossible
81．Why was the sinking of this ship a"scandal"？Because she sank for hitting her own navy's mines/Because she sank for a series of disastrous American mistakes．/Because she sank for American mistakes not for the war．．

15．The common cold is the world's most widespread illness，which is plagues（病疫） that flesh receives．The most widespread fallacy（謬誤） of all is that colds caused by cold．They are not．They are caused by viruses passing on from person to person．You catch a cold by coming into contact，directly or indirectly，with someone who already has one．If cold causes colds，it would be reasonable to expect the Eskimos to suffer from them forever．But they do not．And in isolated arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes．During the First World War soldiers who spent long periods in the trenches（戰(zhàn)壕），cold and wet，showed no increased tendency to catch colds．In the Second World War prisoners at the notorious Auschwitz concentration camp（奧斯維辛集中營），naked and starving，were astonished to find that they seldom had colds．At the Common Cold Research Unit in England，volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time．After taking hot baths，they put on bathing suits，allowed themselves to be with cold water，and then stood about dripping wet in drafty（通風(fēng)良好的）room．Some wore wet socks all day while others exercised in the rain until close to exhaustion．Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose．If，then，cold and wet have nothing to do with catching colds，why are they more frequent in the winter？Despite the most pains-taking research，no one has yet found the answer．One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times，and this makes it easier for cold viruses to be passed on．No one has yet found a cure for the cold．There are drugs and pain suppressors（止痛片） such as aspirin，but all they do is relieve the symptoms．

64．Which of the following does not agree with the chosen passage？C
A．The Eskimos do not suffer from colds all the time．
B．Colds are not caused by cold．
C．People suffer from colds just because they like to stay indoors．
D．A person may catch a cold by touching someone who already has one．
65．Arctic explorers may catch colds whenD．
A．they are working in the isolated arctic regions
B．they are writing reports in terribly cold weather
C．they are free from work in the isolated arctic regions
D．they are coming into touch again with the outside world
66．Volunteers taking part in the experiments in the Common Cold Research UnitA．
A．suffered a lot       B．never caught colds
C．often caught colds   D．became very strong
67．The passage mainly discussesC．
A．the experiments on the common cold
B．the fallacy about the common cold

12．Many people have low iron in their blood．But pregnant women need extra iron for their own health and their baby's health．Iron is important to the development of a baby's brain and central nervous system．
In poor countries，however，providing all pregnant women with iron supplements （補(bǔ)品 ） can be a financial issue．Some experts say giving supplements to babies after they are born is enough．
Someone who disagrees is Parul Christian，a nutritionist at the Johns Hopkins School of Public Health in Maryland．She and other scientists have been doing research in Nepal．She says their latest findings should settle any question about the value of making sure every pregnant woman receivesiron supplements．
Iron is a micronutrient （微營養(yǎng)素）．Micronutrients are important substances that are found in small amounts in foods．
The researchers first completed a study among poor women in Nepal ten years ago．During pregnancy some of the women received supplements containing iron and another micronutrient，folic acid．
Professor Christian says that study showed the supplements could improve child survival．
Now the children are older．The researchers returned to Nepal and tested their neurological （神經(jīng)的）development．They found improved intellectual（智力的） and fine motor abilities among those whose mothers had received iron and folic acid during pregnancy and for three months after．
The findings appear in the Journal of the American Medical Association．
Another new study，published in the journal Pediatrics，looks at levels of vitamin D in babies．It says newborns with the lowest levels were twice as likely to develop respiratory infections（呼吸道感染） as those with normal levels of vitamin D．
Vitamin D helps build strong bones and strengthens the body's defenses against disease．The vitamin is commonly added to cow's milk and also found in supplements．But vitamin D is called the sunshine vitamin．The body naturally produces it from sunlight．
Carlos Camargo from Harvard Medical School in Massachusetts and other researchers did the study．It followed more than nine hundred children in New Zealand until they were five years old．

71．The passage is intended to tell us thatB．
A．iron is as important as Vitamin D to people's health
B．iron and Vitamin D may lead to smarter，healthier children
C．pregnant women need much more iron and Vitamin D
D．in poor countries babies are lacking iron and Vitamin D
72．When expecting a baby，a woman doesn't necessarily receive some extraC．
A．iron            B．folic acid      C．vitamin D      D．supplements
73．It can be learnt from the passage thatD．
A．providing all pregnant women with extra iron may be difficult for all countries
B．plenty of micronutrients can be found in foods that you eat in your daily life
C．a(chǎn)ll the vitamins that you need to keep healthy can be received from the sunlight
D．it's more possible for babies lacking vitamin D to suffer from respiratory infections
74．The underlined words in Paragraph 5refer toA．
A．a(chǎn) micronutrient    B．a(chǎn) food         C．a(chǎn) metal        D．a(chǎn) medicine
75．The passage might be followed by a paragraph aboutC．
A．how the researchers did the study    B．how important the study was
C．what the researchers found           D．what problems the researchers faced．
