分析 -好險(xiǎn)啊!-嗯,要不是路人反應(yīng)快,這這小女孩就溺水了.

解答 答案:C 句意表達(dá)的是相反假設(shè),要用虛擬;對(duì)過(guò)去的虛擬,要用情態(tài)動(dòng)詞加完成時(shí)態(tài);must have done表示對(duì)過(guò)去的推測(cè),不符合句意.故選C.

點(diǎn)評(píng) 虛擬語(yǔ)氣是表示與事實(shí)相反的假設(shè),構(gòu)成方式有:對(duì)現(xiàn)在或?qū)?lái),條件句中用一般過(guò)去時(shí)態(tài),主語(yǔ)用情態(tài)動(dòng)詞加動(dòng)詞原形;對(duì)過(guò)去,條件句中用過(guò)去完成時(shí)態(tài),主語(yǔ)用情態(tài)動(dòng)詞加完成時(shí)態(tài).學(xué)習(xí)時(shí),要牢記構(gòu)成方式.

4.閱讀下面短文,按要求完成閱讀任務(wù).
    It's difficult to find a piece of clothing as widely accepted,worn and loved the world over as jeans.The classic symbol of the American West is now a main item in wardrobe around the world.But why?
    The reason for jeans'success has as much as to do with their cultural meaning as their physical construction.
     Invented by Levi Strauss and Jacob Davis in 1873,jeans were first designed as work wear for laborers on the farms and mines of America's Western states in the late l9th century.They proved extremely comfortable and durable(耐用的)and were soon in high demand.
    But the first explosion of jeans into world of casual-wear(便裝)had more to do with what jeans had come to symbolize.
    When they did start to be worn as casual wear,jeans became a symbol of rebellion-the spirit captured by Marion Brando in his l953 film The Wild One and by James Dean two years later in Rebel Without a Cause,
    Jeans were soon banned in schools from coast to coast which only added to the passion with which teenagers embraced them.
     But jeans'popularity kept growing also because they put different classes on a level playing field.They were affordable and hard-wearing,looked good worn as well as new,and didn't have to be washed often or ironed at all.They conformed to the body in a way that matched even the most finely tailored clothes.This became especially important for women because then,and now,they paid more attention to fit.This versatility(多用途),the ability to become all things to all people,is the secret to jeans'survival as a wardrobe item.
56.By whom were jeans worn at first?(No more than l5 words)Jeans were worn by laborers on the farms and minesin theAmerica West.
57.What made teenagers across the US like wearing jeans even more?(No more than 10 words)Jeans'being banned或The ban on jeans.
58.What will be the best title for this passage?(No more than 10 words)The Reason for Jeans'Success./Why Is Jeans'Popularity.
59.What does the underlined word"embraced"mean?(No more than 3 words)accepted
60.Do you like wearing jean?Why of why not?Please give at least two reasons.(No more than 25 words)Yes,because they put different classes on a level playing field and they have the ability to become all things to all people..

1.Nowadays,a cell phone service is available to everyone,everywhere.Probably thousands of people have already been using it,but I just discovered it,so I'm going to claim it and also name it:Fake Foning.
The technology has been working well for me at the office,but there are unlimited applications,actually in any public space.
Say you work at a big university with lots of talky workmates buzzing about.Now,say you need to use the restroom.The trip down the hall will take approximately one hour,because a person can't walk into those talky people without getting pulled aside for a question,a bit of gossip,a new read on a certain line of Paradise Lost.
So just pick a cell phone up.Don't dial.Just hold that phone to your face and start talking.Walk confidently down the hall engaged in fake conversation,making sure to tailor both the topic and content to the person standing before you whom you are trying to avoid.
For standard colleague avoidance,I suggest fake chatting about fake business:
"Yes,I'm glad you called,because we really need to hammer out the details.What's that?Yes,I read Page 12,but if you look at the bottom of 4,I think you can see the problem begins right there."
Be engaged in your fake fone conversation.Make eye contact with the people passing,nod to them,gesture keen interest in talking to them at a later time,point to your phone,shrug and move on.
There was one important caution about fake foning.The other day I was fake foning my way past a colleague,and he was actually following me to get my attention.I knew he wanted to ask about a project I had not yet finished.I was trying to buy myself some time,so I continued fake foning with my doctor."So I don't need the operation?Oh,doctor,that is the best news."
And then:Brrrrrrng!Brrrrrmg!Brrrrrmg!My phone started ringing,right there while it was planted on my face.My colleague looked at me,and I looked at him,and naturally I gasped."What is the matter?"I said,pulling the phone away to look at it,and then putting it back to my ear.
"Hello?Are you still there?"Oops.
67.According to the passage Fake Foning isA.
A.a(chǎn) strategy to avoid people                  
B.a(chǎn) device newly produced
C.a(chǎn) service provided everywhere              
D.a(chǎn) skill of communication
68.What does the last example show?B
A.One effective way is to fake fone one's doctor.
B.One has to be careful while fake foning.
C.Fake foning may not cheat people.
D.Fake foning is always quite successful.
69.After his phone suddenly began ringing,the authorD.
A.immediately started talking to the caller
B.immediately started talking to his colleague
C.put the phone away and stopped talking
D.continued with his fake conversation
70.What is the tone of the passage?B
A.Critical.B.Humorous.C.Serious.D.Unclear.

8.The word"conservation"has a thrifty (節(jié)儉)meaning.To conserve is to save and protect,to leave what we ourse1ves enjoy in such good condition that others may also share the enjoyment.Our forefathers had no idea that human population would increase faster than the supplies of raw materials; most of them,even until very recently,had this foo1ish idea that the treasures were"1imitless"and"inexbaustible".Most of the citizens or earlier generations knew little or nothing about the complicated and delicate system that runs all through nature,and which means that,as in a 1iving body,an unhealthy condition of one part will sooner or 1ater be harmful to a11the others.
??Fifty years ago nature study was not part of the schoo1work; scientific forestry was a new idea:timber was still cheap because it could be brought in any quantity from distant woodlands; soil destruction and river f1oods were not national problems; nobody had yet studied long-term climatic cycles in relation to proper 1and use; even the word"conservation"had nothing of the meaning that it has for us today.
??For the sake of ourselves and those who will come after us,we must now set about repairing the mistakes of our forefathers.Conservation should,therefore,be made a part of everyone's daily life.To know about the water table(地下水位) in the ground is just as important to us as a knowledge of the basic arithmetic formulas.We need to know why all watersheds need the protection of plant life and why the running current of streams and river must be made to yield their full benefit to the soil before they finally escape to the sea.We need to be taught the duty of planting trees as well as of cutting them.We need to know the importance of big,mature trees,because living space for most of man's fellow creatures on this planet is figured not only in square measure of surface but also in cubic volume above the earth.In brief,it should be our goal to restore as much of the original beauty of nature as we can.

45.The author's attitude towards the present situation in the use of natural resources isC.
A.positive              B.neutral
C.critical              D.suspicious
46.According to the author,the greatest mistake of our forefathers was thatA.
A.they had little or no sense of environmental protection
B.they had no idea about scientific forestry
C.they did not know the importance of nature study
D.they had no idea of how to make good use of raw materials
47.With a view to correcting the mistakes of our forefathers,the author suggests thatD.
A.we plant more trees and make full use of the woodlands
B.we be taught environmental science,as well as the science of plants
C.we return to nature and not use any natural resources at all
D.environmental education be directed toward everyone
48.What does the author imply by saying"living space…above the earth."(the underlined sentence in Paragraph 3)?B
A.Our living space on the earth is getting smaller and smaller in volume.
B.We must create better living conditions for both birds and animals.
C.We need to take some measures to protect space in volume.
D.Our living space should be measured in cubic volume.
