题目内容

4．To learn English well，we should find opportunities to hear English ______ as much as we can．（　　）

A．

speak

B．

spoken

C．

speaking

D．

to speak

分析为了学好英语，我们应该尽可能多地找机会多听．

解答答案：B
句中speak作hear的宾语补足语，speak 与English构成动宾关系，要用表示被动的过去分词，即hear sth done听…被怎样．故选B．

点评过去分词是非谓语动词的一种，用法很灵活，分为简单式done（表示与谓语同时或几乎同时发生的动作）；完成式having been done（表示先于谓语的动作）．学习时，要把握其用法特征：表示被动和完成．同时还要注意区分现在分词和不定式．

15．The common cold is the world's most widespread illness，which is plagues（病疫） that flesh receives．The most widespread fallacy（谬误） 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（战壕），cold and wet，showed no increased tendency to catch colds．In the Second World War prisoners at the notorious Auschwitz concentration camp（奥斯维辛集中营），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（通风良好的）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
C．the reason and the way people catch colds
D．the continued spread of common colds．

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 （补品） 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 （微营养素）．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 （神经的）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．all 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 micronutrient    B．a food         C．a metal        D．a 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．

16．I'm（61）theonly daughter of my parents，so they are worried（62）abouteverything I do．For example，（63）WhenI ride my bike，my parents won't let me（64）ride（ride） by myself．They are afraid I might fall off my bike and hurt（65）myself．They are taking great trouble to support the bike，with my mother even（66）carrying（carry） a first-aid box．I'm not free to ride and I often say （67）angrily（angry），"why not let me ride alone？"
Now，most families have one child．Parents want to do everything for their children．This does no good（68）tothem．Too much love from parents may prevent children from（69）being（be） independent．In my opinion，parents should let their children do（70）whatthey should do alone．
