根据以下材料，回答{TSE}题
The Chinese have used a method called acupuncture(针灸) toperform operations for about 4,000 years without putting the patient to sleep.This involves placing flexible needles (针) into certainparts of the body. The needles used are available in a number of stores inChina and everyone may buy them.
To learn how to use needle takes about onemonth of training. But to be skillful requires greater time. The person whoperforms the acupuncture knows how to put in the needles so the needles themselvesare not painful. This person also knows where to place the needles so thepatient feels no pain in the area where the operation is to be performed. Theneedles are not necessarily inserted near the place where the pain is to beprevented. In the past, a particular operation might require 25 or more needlesplaced in various parts of the body. But now this operation requires only 3 or4 needles.
Today the Chinese doctors are trying tolearn more about acupuncture. They are trying to develop a convincing theory toexplain how the needles work in preventing pain, or why a needle in the wrist,for example, would prevent the pain in the area of the mouth.
A patient who needs an operation is given achoice between having acupuncture or having one of the chemicals used forputting him to sleep. It has been estimated that over half of the patients chooseacupuncture because there is no sickness after the operation whereas (然而，反之) the chemical maymake the patient sick for a few hours or a day.

根据以下材料，回答{TSE}题
Laziness is a sin, everyone knows that.We have probably all had lectures pointing out that laziness is immoral, thatit is wasteful, and that lazy people will never amount to anything in life. Butlaziness can be more harmful than that, and it is often caused by more complexreasons than simple wish to avoid work. Some people who appear to be lazy aresuffering from much more serious problems. They may be so distrustful of theirfellow workers that they are unable to join in any group task for fear ofridicule or fear of having their ideas stolen. These people who seem lazy may beparalyzed by a fear of failure that prevents fruitful work. Or other sorts offantasies (幻想)may prevent work; some people are so busy planning, sometimes planning greatdeals or fantastic achievements that they are unable to deal with whatever"lesser" work is on hand. Still other people are not avoiding work;strictly speaking, they are merely procrastinating--rescheduling their day.
Laziness can actually be helpful. Likeprocrastinators (拖延者), some people may look lazy when they are really thinking,planning, contemplating (沉思), researching. We shouldall remember that great scientific discoveries occurred by chance. Newtonwasn´t working in the orchard when the apple hit him and he devised the theoryof gravity. All of us would like to have someone "lazy" were causedby the worker´s taking time to check each step of his work and to do his jobright. And sometimes, being lazy that is, taking time off for a rest is goodfor the overworked students or executive.
Taking a rest can be particularly helpful tothe athlete who is trying too hard or the doctor who´s simply working himselfovertime too many evenings at the clinic. So be careful when you are tempted tocall someone lazy. That person may be thinking, resting, and planning his orher next book.
{TS} The main idea of this passage isthat ______.
A、laziness is a moral sin
B、there are advantages and disadvantages inbeing lazy
C、laziness is the sign of deep-seatedemotional problems
D、lazy people do more careful work
77
We can learn from the passage that______.
A、laziness is a disease

B、Most assembly workers are lazy.
C、The word "laziness" issometimes applied incorrectly.
D、Most insecure people are lazy.
79

根据以下材料，回答{TSE}题
Every day 25 million U.S. children fideschool buses. The safety record for these buses is much better than forpassenger cars; but nevertheless, about 10 children are killed each year ridingon large school buses, and nearly four times that number arc killed outsidebuses in the loading zones. By and large, however, the nation´s school childrenare transported to and from school safety.
Even though the number of school buscasualties (伤亡事故) is not large, the safety of children is always of intense publicconcern. While everyone wants to see children transported safely, people aredivided about what needs to be done particularly whether seat belts should bemandatory (强制).
Proponents of seat belts on schoolbuses--many of them parents and medical organizations argue that seat belts arcnecessary not only to reduce fatality and injury, but also to teach children lessonsabout the importance of using them routinely in any moving vehicle. A sidebenefit, they point out, is those seats belts help keep children in theirseats, away from the bus driver.
Opponents of seat belt installation suggestthat children are already well protected by the school buses that adhere to theNation Highway Traffic Safety Administrations (NHTSA) safety requirements setin 1977. They also believe that many children won´t wear seat belts anyway andthat may damage the belts or use them as weapons to hurt other children.
A new Research Council report on school bussafety suggests that there are alternate safety devices and procedures that maybe more effective and less expensive. For example, the study committeesuggested that raising seat backs four inches may have the same safetyeffectiveness as seat belts.
The report sponsored by the Department ofTransportation at the request of Congress, reviews seat belts extensively whiletaking a broader look at safety in and around school buses.
{TS} Each year, children killedoutside buses in the loading zones, are about ______.
A、10
B、40
C、30
D、50
82

83
According to the passage, who has thegreatest degree of control of the school buses "safety"?
A、A new Research Council.
B、The Department of Transportation.
C、The Medical Organization.
D、National Highway Traffic SafetyAdministration
84
It may be inferred from this passagethat ______.
A、many of the opponents (反对者) of seat beltinstallation are parents and officials of the Department of Transportation
B、proposals of seat belts on school buseswould be seriously considered
C、an alternate safety device raising seatbacks four inches may be taken into consideration
D、The Department of Transportation mayeither take the idea of seat belts or other measures when it reviews the wholesituation
85

A、Making School Buses Even Safer forChildren
B、Seat Belts Needed on School Buses
C、Alternate Safety Devices and Procedures
D、Safety in and around School Buses

根据以下材料，回答{TSE}题
I had always known that the Chinese NewYear was different from our own but otherwise assumed that the way we Europeansdivided up the year was something in common. Quite recently, though, I foundout that there used to be some pretty dramatic differences. During the MiddleAges, the official start of the year varied enormously within Europe. In Spain,Portugal, Switzerland and Germany it began on Christmas Day, whereas it startedon the 1st March in Venice and the 21st in England. In Rome, it was at one timethe 25th January but then changed to the 25th March. In Russia the new yearcoincided with the spring equinox (春分).
If this isn´t complicated enough the Frenchused to start their official year from Easter day. Easter, as I am sure you allknow, is a moveable feast whose complicated calculation is quite a mystery tome. However, this French style of working out the beginning of the year led tosome years being as short as three hundred days while others could stretch tofour hundred with two spring times with one at each end!
With all these different dating systems inoperation you can imagine the enormous potential for confusion. This can createheadaches for students engaged in studying the period from original documentsas they can actually find somebody´s death being recorded months before theyare married and battles still being fought weeks after a peace agreement hadbeen signed! It would all depend on where the events had been recorded. As anactual example the student could easily get muddled (糊涂的) over the date of thefamous trial of the Knights Templar in Paris. According to records this longand complex trial ended in 1313 as the New Year didn´t officially start untilthe 7th April. Fortunately for all of us these differences were eventuallysolved. In December 1564 the French decided to start the New Year from the 1 stJanuary. The Russians adopted this new style of dating in 1725 and the Englisha further twenty-seven years later.
{TS} The writer______.
A、had always known about the dating systems
B、knew Europeans varied in their datingsystems
C、had just found out about the Chinese NewYear
D、had been forced to revise his opinion
87
What used to be the most common start ofthe official year?
A、Christmas Day.
B、The Spring equinox.
C、1st January.
D、25th March,
88
What was a feature of the Frenchofficial year?
A、It could have two Easters.
B、It could vary in length.
C、It could be shorter than three hundreddays.
D、It often had two summers.
89
Why do students sometimes get confused?
A、Documents are inaccurate.
B、Trials used to be long and complicated.
C、Events appear illogical.
D、Because the New Year started on April7th.
90
The system for the new year starting onJanuary 1st ______
A、was immediately adopted by the English
B、was adopted by the Russians a century,before the French
C、was accepted by the French
D、was adopted by the English in 1750
1、D2、D3、D4、B5、A6、A7、B8、C9、A10、B11、A12、D13、C14、C15、B16、D17、B18、A19、B20、B21、D22、A23、D24、C25、B26、B27、B28、B29、C30、D31、A32、A33、C34、D35、D36、A37、D38、A39、B40、B41、C42、B43、C44、A45、B46、A47、C48、B49、C50、A51、C52、B53、A54、C55、D56、A57、B58、C59、D60、B61、C62、B63、A64、D65、A66、C67、A68、D69、B70、D71、C72、C73、D74、B75、B76、B77、C78、C79、D80、C81、B82、A83、D84、B85、A86、D87、A88、B89、C90、C
1
考查非谓语动词。句意为“角落里的那个男人承认他对公司的经理撒了谎”。Confess to中的to是介词而不是不定式符号，后面必须接动名词(短语)作宾语；且the man与tell之间为主动关系，故选D。
2
考查宾语从句。句意为“虽然安妮对她的成功感到开心，但她想知道她的私生活中会发生什么事”。that引导宾语从句时不能充当句子成分，故排除A。this和it都不可用作连接词，故排除B、C。what引导宾语从句，作wonder的宾语，what在宾语从句中作主语。故选D。
3
考查习惯用法。在动词feel，hear，see，watch，notice，observe，let，have，make等后常接不带to的不定式作宾语补足语。hear sb．do sth．意为“听到某人做某事”，跟动词原形表示主动。句意为“我昕到老师和同学们都夸他”。故选D。
4
考查固定搭配。forget to do sth．“忘记去做某事”，forget doing sth．“忘记做过某事”。结合句意“我永远不会忘记第一次和你见面的情形”可知，B项正确。
5
考查非谓语动词。句意为“早在1647年，俄亥俄州就做出决定，在拥有50户以上居民的每一个城镇都必须建立免费的由税收维持的学校”。句中的every town having 50 households or more为现在分词短语作后置定语，修饰every town，相当于定语从句every town which has 50households or more。
6
考查非谓语动词。当连词as引导状语从句时，从句经常采用倒装语序，将表语、动词原形或状语提到as前面。可实现倒装的状语从句包括让步、原因、方式和比较等四种类型。本题中as引导的是原因状语从句，句意为“这座房子很安静，因为它被孤立在山边”。后半句中的主语it指代主句中的house．分析它和isolate的关系，应用过去分词形式。该题中表语isolated被前置，可还原为“as it was isolated on theside of a mountain”。
7
考查介词辨析。across“穿过，横穿”，throughout“贯穿，遍及”，over“在……的上方，越过”，within“在……之内，在……里面”。句意为“人一生中对卡路里的需求是不同的”。Throughoutone’s life意为“在某人一生中，终生”，符合题意，故答案为B。
8
考查习惯搭配。be opposed to表示“反对”。句意为“委员会全体反对该计划有任何改变”。故选C。 1
9
考查非谓语动词。分析句子成分可知，后半句作伴随状语，follow的逻辑主语是句子的主语programme，其宾语是an introduction，所以用现在分词(短语)形式表示主动，C、D项应排除；这里表示的是伴随，不表示时间的先后，不用完成式，故选A。
10
考查主动语态表示被动含义。当不及物动词与副词连用表示主语的特征的时候。使用主动语态表示被动含义。本句中的动词wear与副词comfortably连用表示这种眼镜的特点。句意为“这种由经验丰富的制造商生产的眼镜带起来很舒服”。故B正确。
11
考查同位语从句。句意为“大多数人认为核战争是疯狂的，但这并不意味着核战争就不会爆发”。本题“most people believe nuclear war wouldbe mad”部分是同位语从句，对fact的内容进行阚释说明：从句意义完整，连接词在从句中不充当任何成分，所以用that引导。which不可引导同位语从句；what和whose在引导从句时在句子充当成分．选项B、C、D均可排除。正确答案为A。
12
考查as引导方式状语从句。在as引导的方式状语从句中，尤其含有be时，常常会省略一部分，而保留其主要成分，如分词或形容词。句中“take drugsas directed”为“take drugs as they are directed”的省略形式。句意为“详细调查表明，多达百分之五十的病人没有按照医嘱服药”。
13
考查主动形式表示被动含义。在want，need，require，deserve，bear等词后面，动名词用主动形式表被动含义，其含义相当于动词不定式的被动形式。本句中的want cutting相当于want to be cut．意思是“你的头发需要剪了”。故C项正确。
14
考查appreciate的用法。appreciate后面用动名词作宾语。句意为“因为他很幽默，人们都喜欢和他一起工作”。本句说的现在的客观状态，不用完成时，D项排除，故选C。
15
考查固定搭配。Have trouble in doing sth．表示“做某事有困难”，其中的介词in可以省略。句意为“有时候孩子们很难把现实与虚构区别开来，可能认为那样的事真的存在”。故选B。
16
考查“介词+关系代词”引导的定语从句。首先，两个分句之间没有连词，所以该句是非限制性定语从句，排除A、B选项。of whom只能指人，of which只能指物。本句先行词是three sons，所以用of whom引导。句意为“这位老人有三个儿子，他们都在战争期间当了兵”。
17
考查连词。句意为“既然我头脑清醒了，我的大脑也开始能更好地工作了”。now that“既然”，引导原因状语从句，相当于since。如选since，要去掉后面的mat。for表示原因时为并列连词，引导的不是从句。despite“尽管”，与句意不符。故答案为B。
18
考查固定句型。not that…，but that…是用not…，but…连接两个that从句，可以看作是It is not that…，but that…的省略，意思是“不是……，而是……”。句意为“不是约翰不想帮你，而是这已经超出了他的能力范围”。
19
考查时态。本题的关键词是by，该词常常与完成时连用，如果后接过去的时间，就用过去完成时；如果后接现在的时间，就用现在完成时；如果后接将来的时间，就用将来完成时。本句意为“我乘坐的火车在今晚八点到达纽约。那时。我要乘坐的飞机将已经起飞离开了”。第二句的then指的就是今晚八点，这是一个将来的时间，所以与将来完成时连用。故选B。

考查动名词作宾语。句意为“只要不是太晚，我不介意你延期做决定”。mind和delay两个词后面跟动名词作宾语。mind sb．／sb．’s doingsth．“介意某人做某事”，delay doing sth．“延迟做某事”。故选B。
21
考查虚拟语气。句意为“如果后天他们在我们离开前到了的话，我们就举行一个盛大的派对”。根据时间状语the day after tomorrow可知这是与将来事实相反的虚拟语气．并且省略了if。主句谓语用would／should／could／might十动词原形．从句谓语用动词过去式或should+动词原形或were+动词不定式。若省略if，则要将从句谓语中的were或should移至主语之前，构成省略倒装。此处从句完整形式为“if they were to arrive before we depart the day after tomorrow”。故选D。
22
考查时态。句意为“一个闯入教堂的小偷被抓了，因为在他衣服上发现的蜡迹来自只有教堂使用的一种蜡烛”。该句是由because引导的原因状语从句。主语中包含定语从句“who broke into a church”，从句中的“found on hisclothes”为插入语，只起到修饰traces of wax的作用。为了使because所引导的句子成分完整，要选择谓语动词。主句为一般过去时，从句动作发生在主句之前，用过去完成时。故选A。
23
考查时态。句意为“直到那时，他的家人已经有六个月没有收到他的信了”。then是过去的时间，until then表示没有收到信这个动作是在then之前，应该使用过去完成时，答案为D。
