Have you ever stayed up late? If so, you know that not getting enough sleep can leave you tired and grumpy . Not sleeping enough can also make it harder to think clearly the next day.
Sleep experts have long known that getting a good night’s sleep is important.
It helps kids perform their best during the day. A recent study shows that sleep helps improve problem--- solving skills and creative thinking.
For the study, two groups of volunteers answered a math problem. The group that slept for eight hours solved the problem correctly more often than the group that did not get enough sleep.
While you sleep, your brain is busy doing its “homework”. It sorts out information from your day. Getting enough sleep each night can boost your brainpower. That will help you do your best in school. Experts say that, in return, can lead to better grades.
What is the best title for the passage?

A．Too Much Sleep	B．It’s Homework Time
C．Sleep to Succeed	D．Math Problems

The underlined word “boost” in paragraph 5 means ________.

A．reduce	B．improve
C．disturb	D．worsen

Why is sleep important?

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.
73.All the following arguments can be found in the passage EXCEPT that       .
A.co-education can produce a society-like situation
B.co-educational schools may lead to love affairs between boys and girls
C.co-education will help develop a better understanding about the opposite sex
D.co-education can make boys perform well in mixed classes
74.Alarmed by the situation ,the UK government encourages        .
A.co-education
B.single-sex education
C.single-sex classes in co-educational schools
D.co-educational classes in single-sex schools
75.At the end of the passage the writer suggests that        .
A.single-sex schools are the best schools in the UK
B.being single-sex does not necessarily make a school better
C.co-educational schools are better for both sexes in personal development
D.because boys cannot compete with girls in study ,they go to single-sex schools

In 1837, the historian Carlyle made the first recorded use of the word " queue" (排队). He spoke of the French and their "habit of standing in a queue". Forty years later Paris was the best place to wait in line.
However, queuing became popular in Britain too. The Second World War was the golden age of queuing, and people joined any line in the hope that it was a queue for something to buy. This was the source of many Second World War jokes:
Shopkeeper to customer : Excuse me, miss, are you pregnant (怀孕)?
Customer : Well, I wasn't when I joined the queue.
Today, according to research in America, we (in Britain) can spend up to 5 years of our lives queuing－ as compared to twelve months looking for things we have lost. But things may be changing. Many people no longer have the patience to stand in a queue. The law of the jungle (丛林) has begun to operate at bus stops, with people using their arms to push others out of the way.
One way to make life easier is to introduce "queue management". Customers at supermarket cheese counters can now take a ticket with a number which appears on a screen when it is their turn. And while they wait for their number, they can do a bit of shopping.
In some booking offices there is also a system telling customers how long they may have to wait before they are served.
One of the latest technical progress is the use of an electronic scanner (电子识别器) which can read all the contents of your shopping basket or trolley in just a few seconds. If these become popular, queuing in supermarkets may become a thing of the past.
But some people just like queuing. One man queued all night for Harrods famous January sale, and then returned home for breakfast at nine o' clock the next morning without going into the shop.
68. The joke in Paragraph 2 implies that the young woman _______.
A. has been waiting in the queue for a long time         B. doesn't need to stand in the queue
C. enjoys standing in the queue                                 D. has stood in the wrong line
69. According to the passage, which of the following is true?
A. The British spend more time queuing than looking for lost things.
B. The Americans criticized the British for their way of queuing.
C. The British are always patient when they wait in line.
D. People queue only when they want to buy something.
70. The British try to solve the problem of queuing by all the following EXCEPT _______.
A. making a law to prevent queuing
B. telling the customers the waiting time
C. using numbered tickets to put the customers in order
D. checking the price of the goods customers buy with a scanner
71. We can infer from the passage that ________.
A. queue management doesn't work well                    B. there is still queuing in England
C. we don't see much queuing in Paris                       D. the French like queuing more than the British

"Have you ever been out on a boat and felt it lifted up by a wave? Or have you jumped in the water and felt the rush of energy as waves came over you?" asked Jamie Taylor of the Wave Energy Group at the University of Edinburgh. "There is certainly a lot of energy in waves," he said.
Scientists are working to use that energy to make electricity. Most waves are created when winds blow across the ocean. "The wind starts out by making little ripples (涟漪) , but if they keep on blowing, those ripples get bigger and bigger and turn into waves," Taylor said. " Waves are one of nature 's ways of picking up energy and then sending it off on a journey.
When waves come toward the shore, people can set up dams to block the water and send it through a large wheel called a turbine (涡轮机) . The turbine can then power an electrical generator to produce electricity.
"The resource is huge," said Janet Swain of the Worldwatch Institute. "We will never run out of wave power. " Besides, wave energy does not create the same pollution as other energy sources, such as oil or coal. Oceans cover three-quarters of the Earth's surface - that would make wave power seem ideal for creating energy throughout the world, though there are some weak points yet to overcome.
Swain said that wave power still costs too much money. She also said that its effects on sea animals are still unknown. What is more, wave power could affect fishing and boat traffic.
Traditional sources of energy like oil and gas may someday run out. " Demand for energy to power our TVs and computers, drive our cars, and heat and cool our homes is rising rapidly throughout the world," Swain said. In the future when you turn on a light, an ocean wave could be providing the electricity!
64. The writer uses the two questions at the beginning of the passage to _______.
A. test the readers' knowledge about waves          B. draw the readers' attention to the topic
C. show Jamie Taylor's importance                            D. invite the readers to answer them
65. The underlined phrase "picking up" (paragraph 2) is closest in meaning to _______.
A. starting again            B. speeding up              C. gathering           D. improving
66. We can make better use of wave energy if we _______.
A. shorten its journey to thousands of homes       B. build more small power stations on the oceans
C. reduce the cost of turning it into electric power
D. quicken the steps of producing electricity
67. It can be inferred that some day we might not worry about ________.
A. air pollution             B. our boat traffic         C. our power supply             D. our supply of sea fish

Being considered a leader in our society is indeed of high praise. Leadership means power, commands respect and, most important, encourages achievement. Unlike vitamin C, leadership skills can't be easily swallowed down. They must be carefully cultivated.
Different from popular belief, most good leaders are made, not born. They learn their skills in their everyday lives. But which do they develop? How do they (and how can you) get others to follow?
Always give credit. Many leaders note that the most efficient way to get a good performance from others is to treat them like heroes. Giving public credit to someone who has earned it is the best leadership technique in the world. It is also an act of generosity (慷慨) that's never forgotten.
Giving credit is more effective than even the most constructive criticism (批评) , which often hurts rather than helps. Kenneth Blanchard, the author of The One-Minute Manager, agrees. "Catch people doing something right!" he says. Then tell everyone about it.
Take informed risks. " The best leaders know that taking a risk is not a thoughtless exercise," says management adviser Marilyn Machlowitz. "Sky divers don't go up in an airplane without checking the parachutes (降落伞) beforehand. "
Because the idea of risk also carries with it the possibility of failure, many of us usually wait for others to take charge. But if you want to be a leader, you must learn to fail － and not die a thousand deaths. Pick yourself up and start all over again.
Encourage enthusiasm (热情). "When people understand the importance of work, they lend their mental strengths," says Lee Ducat. But when they get excited about the work, all their energy gets poured into the job. That's a great force! Is this the best way to create excitement? Be enthusiastic yourself － You will be followed by everyone.
60. The underlined word "cultivated" (paragraph 1) roughly means _______.
A. encouraged        B. compared          C. examined          D. developed
61. The part Always give credit tells us that a leader should _______.
A. give helpful criticism                                          B. regard others as real heroes
C. praise people for their good performances       D. praise everyone
62. To be a good leader, you should _______.
A. not be afraid of any risks                              B. think twice before taking risks
C. try to avoid any possible failures                    D. know what a thoughtless exercise is
63. Which of the following can be the best title for the passage?
A. Leadership Is of Skills and Techniques           B. Leadership Is Very Important
C. Not Many Can Be Leaders                             D. How to Be a Leader

From Mr. Ward Hoffman.
Sir, I was halfway through Professor Raj Persaud's article “What's the tipping point"(Financial Times Weekend, April 9-l0) when it occurred to me that what I was reading was not ironic(讽刺的). If Prof Persaud wants to know why Americans tip in restaurants, he need only ask the first American he meets in London.
Americans tip in restaurants for one reason, and one reason only: we tip to supplement (补贴) the salary of restaurant workers. Quality of service does not enter into it, beyond the fact that one may tip a bit less for poor service, or a little more for good service.
Not tipping at all in a non-fast-food restaurant is not a choice. In the US, one used to tip about 15 per cent for dining in a family-style restaurant or in an upmarket (高档的) restaurant. Here, in San Francisco Bay area restaurants, we are encouraged to tip 20 per cent or more, to help restaurant workers live in this very expensive area.
After eating at an Italian restaurant in my city, I left a tip of 20 per cent on the non-tax part of our dinner bill. It was expected. There is nothing more complicated (复杂的) than that about Americans tipping in restaurants.

From Mr. Philip McBride Johnson.
Sir, I agree with most of Raj Persaud's opinions about the doubtful value of tipping, but with one exception(例外). Tips can be very useful when one is a repeat customer or diner.
It is only when the tipper is a stranger and likely to remain so that the system does not work to his or her advantage. But frequent a hotel or a restaurant, always tip a bit more, and the difference in service and treatment will be easily felt.
