When you think of the tremendous technological progress we have made, it’s amazing how little we have developed in other respects. We may speak contemptuously of the poor old Romans because they relished the orgies of slaughter that went on in their arenas. We may despise them because they mistook these goings on for entertainment. We may forgive them condescendingly because they lived 2000 years ago and obviously knew no better. But are our feelings of superiority really justified? Are we any less blood-thirsty? Why do boxing matches, for instance, attract such universal interest? Don’t the spectators who attend them hope they will see some violence? Human beings remains as bloodthirsty as ever they were. The only difference between ourselves and the Romans is that while they were honest enough to admit that they enjoyed watching hungey lions tearing people apart and eating them alive, we find all sorts of sophisticated arguments to defend sports which should have been banned long age; sports which are quite as barbarous as, say, public hangings or bearbaiting.
It really is incredible that in this day and age we should still allow hunting or bull-fighting, that we should be prepared to sit back and watch two men batter each other to pulp in a boxing ring, that we should be relatively unmoved by the sight of one or a number of racing cars crashing and bursting into flames. Let us not deceive ourselves. Any talk of ‘the sporting spirit’ is sheer hypocrisy. People take part in violent sports because of the high rewards they bring. Spectators are willing to pay vast sums of money to see violence. A world heavyweight championship match, for instance, is front page news. Millions of people are disappointed if a big fight is over in two rounds instead of fifteen. They feel disappointment because they have been deprived of the exquisite pleasure of witnessing prolonged torture and violence.
Why should we ban violent sports if people enjoy them so much? You may well ask. The answer is simple: they are uncivilized. For centuries man has been trying to improve himself spiritually and emotionally – admittedly with little success. But at least we no longer tolerate the sight madmen cooped up in cages, or public floggings of any of the countless other barbaric practices which were common in the past. Prisons are no longer the grim forbidding places they used to be. Social welfare systems are in operation in many parts of the world. Big efforts are being made to distribute wealth fairly. These changes have come about not because human beings have suddenly and unaccountably improved, but because positive steps were taken to change the law. The law is the biggest instrument of social change that we have and it may exert great civilizing influence. If we banned dangerous and violent sports, we would be moving one step further to improving mankind. We would recognize that violence is degrading and unworthy of human beings.

寫作方法與文章大意
作者采取先對比、后分析的寫作手法。先是今人和古羅馬人對暴虐體育上對此兩者都欣賞。后者坦率成人“欣賞暴力體育”，前者施以各種接口、實際都是嗜血成性者。第二段進一步剖析今人欣賞暴虐體育的種種實例，最后指出改善“暴虐”的根本嗜為改善法律采取積極的步驟，法律才能施以巨大的文明影響，否則人類很難改變。

小題1:A
小題2:A
小題3:D
小題4:B
小題5:A

小題1:A.  不太高。文章一開始就點出科技巨大進步，而其他方面進展很少。人們以輕蔑的口氣談及可憐的古羅馬人，因為他們欣賞競技場上的屠殺。我們輕視他們，因為他們把這些屠殺視為娛樂。我們可以降階/屈尊地諒解他們，因為他們生活在2000年前，顯然，對好的東西不知道。在這里作者反問，我們的優(yōu)越感是否正確呢？我們的嗜血性是不是少一些？為什么拳擊比賽吸引那么許多人？在場的觀賞者（觀眾）是不是也希望看到一些暴力呢？結(jié)論是：人類和過去一樣殘忍。唯一的不同點在于古羅馬人很誠實，他們承認他們欣賞觀看饑餓的獅子把人撕碎，活生生吃掉，而我們會找出各種精辟的理由來保衛(wèi)早該制止的運動。第二段舉出具體例子，如斗牛、拳擊中把人打癱在地、車賽中，車子碰撞起火，人們就坐在那里觀看欣賞，參賽者是為了高報酬，觀眾付出大筆錢財是為了看到暴力。作者指出任何體育精神的說法純粹是虛偽。如果一場打比賽（世界重量級冠軍賽），兩輪而不是十五輪就告結(jié)束，成千上百萬人們會感到失望――這些都證明人的卑下，不文明。這兩段似乎也證明作者的觀點應(yīng)該是C項――蔑視的。但在第三段談及，好幾個世紀(jì)以來，人們一直試圖在精神上和情感上改善自己，又得承認不怎么成功�？芍辽傥覀儾辉偃萑摊�?cè)私d于籠中，當(dāng)眾鞭撻，以及其他許多過去普遍存在的野蠻行徑。監(jiān)獄也不再是過去那種令人窒息的禁錮之地，社會福利制度在全世界許多地方推行。在財富公平分配上也作了很大的努力。這些變化的出現(xiàn)不是因為人突然改善，而是在改變法律上采取了 積極的步驟。如果我們禁止危險的暴力體育項目，那么我們在改善人類方面又前進了一步。我們會認識暴力是人類的墮落和卑下（人類不應(yīng)有的）。從這段來看，作者對人類還抱有希望，不是很蔑視。所以選A項。
小題2:A.  法律應(yīng)禁止墮落而又危險的體育項目。見第一題注釋。作者從古羅馬人欣賞殘忍的體育項目說起，點出現(xiàn)代人也是嗜血成性，喜歡暴力體育項目。這是不文明，是墮落。必須制止，而法律是我們社會改革最強大的工具，它可應(yīng)用，發(fā)揮強大的文明影響（第三段倒數(shù)第三句）B. 人們愿意支付巨大款項來觀看暴力。這是作者說明“嗜血成性”的具體內(nèi)容之一。C. 對比對危險體育項目不同的態(tài)度。這里沒有對比。D.人類嗜血成性。這是作者認為人們?yōu)槭裁葱蕾p危險殘忍體育項目的根源。
小題3:D.  人們在體育上習(xí)慣于“嗜血成性”，過去是，現(xiàn)在仍然是，不同點只是前者坦直承認，后者婉轉(zhuǎn)掩飾。見第一題注釋。
A. 把古羅馬人和現(xiàn)代人對比。這項沒有說明對比什么。B. 給出一個例子。太抽象。C. 說明過去人類不太知道更美好的東西，這兩項都沒有到位。
小題4:.B.  5個。作者提到⑴逗熊游戲；⑵斗牛；⑶車賽；⑷拳擊；⑸人獅斗。至于當(dāng)眾鞭撻和絞刑不能稱作體育活動。
小題5:A.  通過制止野蠻體育項目，我們能改善人類自身。這在第三段講的最透徹，見第一題和第二題注釋。
B. 通過制止野蠻體育活動，我們能改善法律，不完全對。作者明確指出要用法律來禁止野蠻體育項目。C. 我們必須采取積極步驟來改善社會福利體制。D. 去表明法律是社會變革的主要工具。

Play is the basic business of childhood, and in recent years research has shown the great impor­tance of play in the development of a human being. From earliest infancy (嬰兒), every child needs opportunity and the right materials for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and play. To succeed in this, they must be good toys, which children will play with often, and will come back to again, and again. Therefore it is important to choose suit­able toys for different stages of a child’s development.
In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited (遺傳的) abilities, is largely determined in the first three years of his life. So a baby’s ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.
In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability: Bricks and jigsaws (七巧板) and construction toys; painting, scribbling (涂鴉) and making things; sand and water play;toys for imaginative and pretending play — the first so­cial games for learning to play and get on with others.
But at the third stage of play development — from five to seven or eight years old — the child is at school. But for a few more years play is still the best way of learning, at home or at school. It is easier to see which type of toys the child most enjoys.
Until the age of seven or eight, play and work mean much the same to a child. But once reading has been mastered, then books become the main source of learning. Toys are still interesting and val­uable, which lead up to new hobbies, but their significance has changed — to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.
小題1:according to the first passage we know that as a child grows up________.
A．he should be allowed to choose his own toys
B．he should be given the same toys
C．he should be given different toys
D．he should be given fewer and fewer toys
小題2:according to the passage, the abilities a child has inherited from his parents________.
A．determine his character
B．will not change after the age of three
C．partly determine the standard he is likely to reach
D．to a large extent determine the choice of toys
小題3:We learn from the passage that a child has boundless curiosity________.
A．when he is twoB．when he is around four
C．when he is sixD．when he is eight
小題4: The passage is mainly about________.
A．the importance of pre-school education B．the importance of schooling
C．the role of play in a child’s developmentD．the choice of toys for youngster

Among various programs, TV talk shows have covered every inch of space on daytime television. And anyone who watches them regularly knows that each one is different in style. But no two shows are more opposite in content, while at the same time standing out above the rest, than the Jerry Springer and Oprah Winfrey shows.
Jerry Springer could easily be considered the king of "rubbish talk". The topics on his show are as surprising as can be. For example, the show takes the ever-common talk show titles of love, sex, cheating, and hate, to a different level. Clearly, the Jerry Springer show is about the dark side of society, yet people are willing to eat up the troubles of other people's lives.
Like Jerry Springer, Oprah Winfrey takes the TV talk show to its top. But Oprah goes in the opposite direction. The show is mainly about the improvement of society and different quality of life. Contents are from teaching your children lessons, managing your work week, to getting to know your neighbors.
Compared to Oprah, the Jerry Springer show looks like poisonous waste being poured into society. Jerry ends every show with a "final word". He makes a small speech about the entire idea of the show. Hopefully, this is the part where most people will learn something very valuable.
Clean as it is, the Oprah show is not for everyone. The show's main audience are middle-class Americans. Most of the people have the time, money and ability to deal with life's tough problems. Jerry Springer, on the other hand, has more of a connection with the young adults of society. These are 18-to 21year-olds whose main troubles in life include love, relationship, sex, money and drug. They are the ones who see some value and lessons to be learned through the show's exploitation.
46. Compared with other TV talk shows, both the Jerry Springer and the Oprah Winfrey shows are ______.
A. more interesting          B. unusually poplar       C. more detailed           D. more formal
47. Though the social problems Jerry Springer talks about appear unpleasant, people who watch the shows ______.
A. show disbelief in them                                         B. are ready to face up to them
C. remain cold to them                                     D. are willing to get away from them
48. Which of the following is likely to be a topic of the Oprah Winfrey show?
A. A new type of robot.                                    B. National hatred.
C. Family income planning.                              D. Street accident.
49. We can learn from the passage that the two talk shows ____.
A. have become the only ones of its kind                   B. exploit the weaknesses in human nature
C. appear at different times of the day                    D. attract different people
50. What is the advantage of the Jerry Springer show?
A. The show exposes the dark sides of society.
B. The show pours poisonous waste into society.
C. Jerry sums up the whole idea of the show.
D. Jerry talks abou the improvement of society.

Computers can injure you. Most other injuries happen suddenly. For example, if you fall off a bike and break your arms, it happens very quickly. But computer injuries happen slowly.
You probably know how to ride a bike safely. Now learn to use a computer safely.
Your eyes--Too much light can injure your eyes, so never sit too close to a computer screen. Your eyes should be at least 50 centimeters (厘米) from the screen. Remember to look away from it sometimes. This gives your eyes a rest.

Your hands--Hand injuries can happen because the hands are moved in the same way hundreds of times. If you use a keyboard for a long time, follow this rule: Stop sometimes and exercise your hands and fingers in different ways.
Your back--Some people sit for many hours in front of a computer. If you sit in the wrong way, you can injure your back and your neck. So you should sit with your back straight.

Drinking eight cups or two litres of water a day is longstanding advice. But is there any scientific basis for it, asks Dr Chris van Tulleken.
You know those ads that remind us that even a small drop in hydration（水合作用） levels can massively affect performance so you need to keep hydrated with whatever brand of super drink they're selling?
They seem pretty scientific don't they? Man in white coat, athlete with electrodes attached and so on. And it's not a hard sell because drinking feels right - you're hot and sweating so surely replacing that fluid must be beneficial.
Well earlier this year sports scientists in Australia did an extraordinary experiment that had never been done before.This group wanted to find out what happened to performance after dehydration. So they took a group of cyclists and exercised them until they lost 3% of their total body weight in sweat.
Then their performance was assessed after rehydration with either 1) nothing, 2) enough water to bring them back to 2% dehydration or 3) after full rehydration.
So far nothing unusual, but the difference between this and almost every other study that's ever been done on hydration was that the cyclists were blind to how much water they got. The fluid was given intravenously without them knowing the volume.
This is vital because we all, and especially athletes, have such an intimate(密切的)psychological relationship with water consumption.
Remarkably, there was no performance difference between those that were fully rehydrated and those that got nothing. This study was part of a growing movement to "drink to thirst" which hopes to persuade athletes not to over hydrate with the potentially fatal consequence of diluting your sodium level, causing hyponatraemia.
Perhaps the result shouldn't be so surprising. Humans evolved doing intense exercise in extreme heat and dryness. We are able to tolerate losses in water relatively well whereas even slight over hydration can be far more dangerous. In simple terms, being too watery is as bad for you as being too concentrated.
小題1:What’s the main idea of the passage?
A．There is no scientific basis for drinking eight cups of water a day
B．People used to drink eight cups of water a day
C．An experiment about whether people should drink eight cups of water.
D．People shouldn’t believe longstanding advice.
小題2:what does the word“dehydration ”in paragragh 4 mean？
A．doing exerciseB．losing water
C．drinking waterD．having a rest
小題3:What is NOT TRUE according to the passage?
A．Drinking too much water is bad for us
B．Sports scientists in Australia did an extraordinary experiment for the first time.
C．Those that were fully rehydrated and those that got nothing performed differently.
D．The cyclists didn’t know how much water they got.
小題4:What can we learn from the last paragragh?
A．Humans can bear losing water relatively well
B．It’s dangerous to drink water.
C．Athletes should drink more water than others.
D．This study was part of a growing movement to "drink to thirst".

Imagine you are doing this reading in this text on the computer; what else are you doing? Maybe you’re eating a sandwich or drinking a cup of Starbucks. Should you eat while reading?
There aren’t many believable numbers, but we do know the number of people who eat while sitting in front of some type of screen is growing. A recent study found that 33 percent of families always have the TV on during meal times and another 27 percent people have it on at least half the time. Another 10 percent may be texting, emailing or talking on a cell phone while eating.
Any type of these behaviors is bad, considering the following evidence:
A Canadian study found that children who watch more than three hours of cartoons a day are 50 percent more likely to be fat than children who watch fewer than two hours. The researchers concluded that more than 60 percent of overweight incidents can be connected with screen watching too much.
A three-week study found that adults who usually play with smartphones less burned 119 more calories per day.
One Chicago researcher found that people eat more potato chips while reading online than when they have the laptop turned off.
There has been very little investigation(調(diào)查) into eating with your eyes staring at a screen or reading a book, but it is likely that his mindless eating is related to weight gain. Simply speaking, your brain has no idea what is going on with your mouth because it is occupied by other things. You don’t notice how full your stomach is, and you often don’t even notice the taste or the act of chewing and swallowing, as a result of which, developing an adapted dietary habit is a must.

A．stories and explanationsB．examples and investigations
C．a(chǎn)n argument and evidenceD．facts and descriptions

B．Adults’ weight is not affected by their eating habits.
C．There exist many investigations into eating while reading.
