The twentieth century saw greater changes than any century before changes for the better, changes for the worse, changes that brought a lot of benefits to human beings, changes that put man in danger .Many things caused the changes, but, in my opinion, the most important was the progress in science.
Scientific research in physics and biology has vastly broadened our views. It has given us a deeper knowledge of the structure of matter and of the universe, it has brought us a better understanding of the nature of life and of its continuous development. Technology in the application of science has made big advances that have benefited us in nearly every part of life.
The continuation of such activities in the twenty-first century will result in even greater advantages to human beings: in pure science—a wider and deeper knowledge in all fields of learning; in applied science—a more reasonable sharing of material benefits, and better protection of the environment.
Sadly, however, there is another side to the picture. The creativity of science has been employed in doing damage to mankind. The application of science and technology to the development and production of weapons of mass destruction has created a real danger to the continued existence of the human race on this planet. We have seen this happen in the case of nuclear weapons, Although their actual use has so far occurred only in the Second World War, the number of nuclear weapons that were produced and made ready for use was so large that if the weapons had actually been used, the result could have been the ruin of the human race, as well as of many kinds of animals.
William Shakespeare said. “The web of our life is of a mingled yarn（纱线）, good and ill together. “The above brief review of the application of only one part of human activities—science seems to prove what Shakespeare said. But does it have to be so? Must the ill always go together with the good? Are we biologically programmed for war?
72．Which of the following best shows the structure of the passage?
I receive a lot of emails every time a column is published in 21st Century. The majority of questions I get are like this: “My English is still very poor, could you please give me some advice?” Since this kind of question is so big and so vague, any answers will be too broad or too general. In fact, asking questions is an art that needs training and practice in itself. And I would like to offer the following tips:
Always contextualize your question. If you really want to ask for advice on something, you need to provide a brief description of how you came up with the question and how you can benefit from asking it. For instance, if you need to improve your English, you need to state the skill area you are in the greatest need of improving, and what difficulties you encounter that cause you so many problems
The second piece of advice is that your question should be focused and specific. By that I mean that you might have a lot of questions, but choose the one that is most important and at the same time the least complicated.
Third, you can practise asking one question in multiple ways. For instance, if you are interested in knowing how you can boost your confidence in speaking, you might consider asking: “I often feel nervous before I ask a question, how can I overcome my anxiety?” “Could you share with me your experience of speaking in front of others?”
Of course, the best way to ask good questions is through the practice of questioning. I highly encourage you to seek opportunities to ask questions. It takes time to be a really good questioner.

In the course of working my way through school, I took many jobs I would rather forget. But none of these jobs was as dreadful as my job in an apple plant. The work was hard; the pay was poor; and, most of all, the working conditions were terrible.
First of all, the job made huge demands on my strength. For ten hours a night, I took boxes that rolled down a metal track and piled them onto a truck. Each box contained twelve heavy bottles of apple juice. I once figured out that I was lifting an average of twelve tons of apple juice every night.
I would not have minded the difficulty of the work so much if the pay had not been so poor. I was paid the lowest wage of that time—two dollars an hour. Because of the low pay, I felt eager to get as much as possible. I usually worked twelve hours a night but did not take home much more than $ 100 a week.
But even more than the low pay, what made me unhappy was the working conditions. During work I was limited to two ten-minute breaks and an unpaid half hour for lunch. Most of my time was spent outside loading trucks with those heavy boxes in near-zero-degree temperatures. The steel floors of the trucks were like ice, which made my feet feel like stone. And after the production line shut down at night and most people left, I had to spend two hours alone cleaning the floor.
I stayed on the job for five months, all the while hating the difficulty of the work, the poor money, and the conditions under which I worked. By the time I left, I was determined never to go back there again.
Some twenty years ago, the performance of girls and boys in class was compared. 71 Now, the situation is reversed (颠倒) with girls consistently doing better than boys.
72 John Dunsford, leader of the association of head teachers of secondary schools, says that the academic failure of boys is a problem which had its roots in society rather than the classroom. Girls, more than boys, see education as a passport to a good job. On the other hand, according to Penny Lewis, a head teacher, young men lack confidence, which they hide with a show of bravado (逞能). They’re uncertain about their place in society. 73
Moreover, boys may learn in a different way from girls, preferring small amounts of work with immediate headlines rather than large projects stretching (延续) into the distance. And education is not seen as “cool”. 74
This is not just a problem in Britain. In a study by the Organization for Economic Cooperation and Development and UNESCO, girls did better than boys at reading at the age of 15 in all 45 countries. The UK ranks ninth out of the 45 countries for reading despite the fact that pupils in the UK spend less time reading than in most other countries. 75
A. So, what has gone wrong with the boys, and what can be done about it?
B. Interestingly, the study suggested that British children read for pleasure more often than those in other countries.
C. Boys scored better in exams, so various measures were introduced to improve the performance of girls, including having single sex girl-only classes.
D. This study can offer a great help to teachers and school leaders in terms of proper education to different people.
E. Some boys grow up in families where there is no male role model to follow.
F. As one contributoe to a BBC website put it, “Girls achieve more at school because they are watching the future while the boys are watching the girls.”
Do you have any strong opinion on co-educational or single-sex schools?
A supporter of co-educational schools would probably say that schools should be like the societies they belong to .In Hong Kong, men and women mix socially on a day-to-day basis .In many fields men are even likely to have female bosses. It is, therefore, desirable that boys and girls grow up together, go to school together, and prepare themselves for a society that does not value sexual separation.
Some would go on to argue further that growing up with members of the opposite sex is important for personal development. Regular contact（接触）can remove the strange ideas about the opposite-sex and lead to more natural relationships. Single-sex conditions are seen as leading to more extreme opinions, and possibly even as encouraging homosexuality（同性恋）, though there is no proof that this is the case.
Those who are against coeducation often also fix their attention on the sexual side. Some parents fear that close contact with members of the opposite sex is dangerous for teenagers. They want their children to be attentive to their studies. Such parents feel uncomfortable with modern ways and the free mixing of the sexes.
A stronger argument comes from research into school results. Girls grow up earlier than
boys ,tend to be more orderly and are likely to be better at languages. In a mixed class ,boys who might do well in a single-sex class become discouraged and take on the rule of troublemaker. Certainly in the UK this situation has greatly alarmed （惊动）the government for it to be encouraging co-educational schools to have some single-sex classes. In the UK the best schools are all single-sex, strongly suggesting that co-education is not the best answer. This may, however, not be as simple as it looks. It may simply be that the famous old schools that attract the best students happen to be single-sex, rather than that being single-sex makes them better schools.
72．In the third paragraph, by saying “though there is no proof that this is the case”, the writer means that .
A．students in single-sex schools will certainly become homosexual
B．students in co-educational schools cannot have extreme opinions
C．students in co-educational schools are likely to be homosexual
D．single-sex school conditions may or may not have effects on the students

Have you ever had the strange feeling that you were being watched? You turned around and, sure enough, someone was looking right at you!
Parapsychologists (灵学家) say that humans have a natural ability to sense when someone is looking at them. To research whether such a “sixth sense”really exists, Robert Baker, a psychologist(心理学家)at the University of Kentucky, performed two experiments.
In the first one, Baker sat behind unknowing people in public places and stared at the backs of their heads for 5 to 15 minutes. The subjects（受试者）were eating, drinking, reading，studying, watching TV, or working at a computer. Baker made sure that the people could not tell that he was sitting behind them during those periods. Later, when he questioned the subjects, almost all of them said they had no sense that someone was staring at them.
For the second experiment, Baker told the subjects that they would be stared at from time to time from behind a two way mirror in a laboratory setting. The people had to write down when they felt they were being stared at and when they weren’t. Baker found that the subjects were no better at telling when they were stared at and when they weren’t .Baker found that the subjects were no better at telling when they were stared at than if they had just guessed.
Baker concludes that people do not have the ability to sense when they’re being stared at. If people doubt the outcome of his two experiments, said Baker, “I suggest they repeat the experiments and see for themselves.”
68. The purpose of the two experiments is to .
A. explain when people can have a sixth sense
B. show how people act while being watched in the lab
C. study whether humans can sense when they are stared at
She is widely seen as proof that good looks can last forever. But, at nearly 500 years of age, time is catching up with the Mona Lisa.
“The thin, wooden panel on which the Mona Lisa is painted in oil has changed shape since experts checked it two years age,” the museum said. 72 .
73 “It is very interesting that when you’re not looking at her, she seems to be smiling, and then you look at her and she stops,” said Professor Margaret Livingstone of Harvard University, “It’s because direct vision is excellent at picking up detail, but less suited to looking at shadows. Da Vinci painted the smile in shadows.”
74 Da Vinci himself loved it so much that he always carried it with him, until it was eventually sold to France’s King Francis I in 1519.
In 1911, the painting was stolen from the Louvre by a former employee, who took it out of the museum hidden under his coat. He said he planned to return it to Italy. The painting was sent back to France two years later.
A. Nearly 6 million people go to see the Mona Lisa every year, many attracted by the mystery of her smile.
B. However, the actual history of the Mona Lisa is just as mysterious as the smile.
C. Visitors have notice the changes but repairing the world’s most famous painting is not easy. Experts are not sure about the materials the Italian artist used and their current chemical state.
D. The health of the famous picture, painted by Leonardo Da Vinci in 1905, is getting worse by the year, according to the Louvre Museum where it is housed.
E. The picture is now so valuable that no one can tell its exact price. Therefore, many thieves tried to steal it in any way they could think of.
F. During World War II, French did the painting in small towns to keep it out of the hands of German forces. Like many old ladies, the Mona Lisa has some interesting stories to tell.
