How to protect children Web-surfers from unsuitable material on-line while encouraging them to use the Internet has long been discussed in the USA.

For some parents the Internet can seem like a jungle, filled with danger for their children. But jungles contain wonders as well as danger and, with good guides, some education and a few precautions(預(yù)防措施), the wilds of the Internet can be safely navigated (航行). "Kids have to be on-line. If we tell our kids they can't have access(進(jìn)入) to the Internet, we're cutting them off from their future," said an expert.

Most kids have started to learn to use search engines. Many of them are great for finding tons of interesting Internet sites, and they can also locate places where you might not want your kids to go. There are search engines designed especially just for kids. A certain software contains only sites that have been selected as safe. But the most popular way to limit access would be to use what is known as a "content screener(過(guò)濾) ". This can't be wholly reliable, and the best thing parents can do is to talk to their kids and let them know what's OK or not OK to see or do on the Internet. Another way is that the mother or father is nearby when the child is surfing the Internet.

A few other tips:

-Don't put the PC in a child's room but keep it in an area where a mum or dad can keep an eye on things. That also makes the Internet more of a family activity.

-Ask your child what he or she has been doing and about any friends they make on-line.

-Tell your child not to give on-line strangers personal information, especially details like address and phone number.

-And tell your children never to talk to anyone they meet on-line over the phone, send them anything, accept anything from them or agree to meet with them unless you go along.

1. What is the best way to protect children from improper materials?

A. To install a content screener in the computer.

B. To buy some search engines for the children.

C. To be nearby when they are surfing the Internet.

D. To talk to the children and persuade them to tell right from wrong.

2. Which of the following is right according to the passage?

A. Surfing the Internet is the best method of educating children.

B. Children's not having access to the Internet may have an effect on their progress.

C. Using a content screener is the most reliable way to allow children to have access to the Internet.

D. Search engines can help children to select materials fit for them.

3. What is the passage mainly about?

A. American children's going on-line. B. The Internet in America.

C. Appreciating the Internet.

D. Opposing the Internet.

1. D。第三段倒數(shù)第二句即本題答案出處。2. B。第二段最后一句即本題答案出處。3. A。短文第一句即整篇文章的主題句,本文主要講述的是,在美國(guó),應(yīng)該鼓勵(lì)孩子們上網(wǎng),但要采取措施使他們明辨是非。

Today, thanks to a number of modern innovations and inventions, the surfing population on the North Shore has exploded．Wave riders and spectators from around the world gather here from November to February, hoping to catch that perfect wave．Winter wave heights can get as high as 20 feet, with faces up to 50 feet! This extreme surf is for experts only, and even then conditions are considered highly dangerous．
World-known surf contests are held here from early November to late December．The Van’s Triple Crown of Surfing, which includes the Vans Hawaiian Pro at Ali’ i Beach Park in Hale’ iwa, the Rip Curl Cup at Sunset Beach, brings together the world’s best professional surfers．Watching them surfing on the grand waves is really a feast for the eyes．

Spending as little as $5 a day on someone else could significantly boost happiness, the team at the University of British Columbia and Harvard Business School found on Thursday.
Their experiments on more than 630 Americans showed they were measurably happier when they spent money on others—even if they thought spending the money on themselves would make them happier.
“We wanted to test our theory that how people spend their money is at least as important as how much money they earn,” said Elizabeth Dunn, a psychologist at the University of British Columbia. They asked their 600 volunteers first to rate their general happiness, report their annual (yearly) income and detail their monthly spending including bills, gifts for themselves, girls for others and donations to charity.
“Regardless of how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not,” Dunn said in a statement.
Dunn’s team also surveyed 16 employees at a company in Boston before and after they received an annual profit-sharing bonus of between $3,000 and $8,000. “Employees who devoted more of their bonus to pro-social spending experienced greater happiness after receiving the bonus and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself” they wrote in their report, published in the journal Science.
　　They gave their volunteers $5 or $20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it.
“These findings suggest that very minor alterations (changes) in spending allocations (shares)—as little as $5—may be enough to produce real gains in happiness on a given day，”Dunn said.
60. What is the general idea of the passage?
A. The more you earn, the greater happiness you will get.
B. Spending more money on yourself will make you happier.
C. Money can buy happiness, but only if you spend it on someone else.
D. You can spend only 5$ a day to get happiness.
61. The underlined word “boost” in the first paragraph probably means_______.
A. help to find     B. help to bring    C. help to increase     D. help to get
62. Which of the following statements is NOT true according to the passage?
A. Those who spend more money on others can get much more bonus.
B. People usually think spending money on themselves will make them happier.
C. Very small changes in spending your money may be enough to gain happiness.
D. Researchers think that how people spend their money is at least as important as how much money they earn.
63. It can be inferred from the 6th paragraph that ______.
A. the volunteers not given 5$ or 20$ spent their own money on themselves.
B. those who spent the money on someone or something else felt happier about it.
C. the volunteers were given 5$ or 20$ as a reward for the experiment.
D. half of the volunteers could spend the money as they liked.

There is no doubt that Apple is well aware of the increased competition in the market and could be in a hurry to put another product out there, said Ramon Llamas, senior research analyst at IDC Mobile Devices Technology and Trends. Given its history with product launches and business policy, though, Apple probably isn’t going to rush an iPhone release simply to put it on shelves, he said.

“If you’re Tim Cook (CEO of Apple), you’re thinking if you want to pay more attention to how to keep growing that bottom line and keep investors(投資人) happy, or continue with the same approach from Apple, which is do what we can do and manage products and releases in the best way they can work for us. Apple usually does things in their own time, and I’m having a hard time buying this May or June timeline.” Llamas told Mac News World.

While it’s probable that Apple is surely in a testing stage for its next smartphone, consumers likely have a standard wait for the finished product, said Colin Gibbs, analyst at GigaOm Pro.

“It typically takes a year or longer to create a state-of-the-art smartphone, so no one should be surprised Apple is in the testing stages with the next iPhone. And while it’s possible that Apple could launch the next iPhone this spring or summer, I’m not expecting to see it until a little later in the year,” he told Mac News World.

When it does launch, though, it could be in a variety of colors, said Gibbs. “Apple has already tested the waters with releasing colored products when it revamped (更新，翻新）its iPod line last fall, so it is understood that it would want the new change with its smartphone, as well”.

“I wouldn’t be surprised if the new iPhone becomes available in some new colors,’’ he said. “That could be done pretty cheaply, and it would give Apple a new marketing angle.”

1.According to Ramon Llamas, Apple always ______.

A. tries to please its investors

B. rushes to put new products to market

C. ignores the fierce market competition

D. does things as planned

2.As for the next iPhone, Colin Gibbs didn’t mention ______.

A. the stage of its being tested

B. the rough time of its being released

C. the function to be improved

D. the wide variety of its color

3.What’s Colin Gibbs’ attitude towards the next iPhone?

A. Disapproving.    B. Indifferent (漠不關(guān)心的).      C. Doubtful.     D. Objective.

4.This passage is presented in the form of ______.

A. stories            B. comments           C. advertisements         D. debates

Below is some advice on how to sleep better.

1. Maintain a regular bed and wake time schedule

Go to bed at the same time every night. Choose a time when you normally feel tired, so that you don’t toss or turn. Try not to break this routine on weekends when it may be tempting to stay up late. If you want lo change your bedtime, help your body adjust by making the change in small daily increments, such as 15 minutes earlier or later each day. As with your bedtime, try to maintain your regular wake-time even on weekends.

2.Fight after-dinner drowsiness（睡意）

If you find yourself getting sleepy before your bed-time, get off the couch and do something mildly stimulating to avoid falling asleep, such as washing the dishes, calling a friend, or getting clothes ready for the next day. If you give in to the drowsiness, you may wake up later in the night and have trouble getting back to sleep.

3. Keep your room dark and cool

When it’s time to sleep, make sure that your environment is dark. Even dim light — especially those from TV or computer screens — can confuse the body clock. Heavy curtains or shades can help block light from windows, or you can try an eye mask to cover your eyes. The temperature of your bedroom also affects sleep. A bedroom that is too hot or too cold can interfere with quality sleep.

4. Turn off your television

Many people use the television to fall asleep or relax at the end of the day. You may even have a television in your bedroom. However, television actually stimulates the mind, rather than relaxing it. Part of this is due to con­tent. Late night news and prime time shows frequently have disturbing, violent material. Even non-violent pro­gramming can have commercials that are jarring and loud.

5. Exercise early

Exercise helps promote restful sleep if it is done sev­eral hours before you go to bed. Exercise can help you fall asleep faster and sleep more soundly — as long as it ’s done at the right time. Try to finish exercising at least three hours before bed or work out earlier in the day.

6. Consult your doctor

Use a sleep diary and talk to your doctor. Note what type of sleep problem is affecting your sleep or if you are sleepy when you wish to be awake and alert. Try these tips and record your sleep and sleep-related activities in a sleep diary. If problems continue, discuss the sleep diary with your doctor. There may be an underlying cause and you will want to be properly diagnosed. Your doctor will help treat the problem or may refer you to a sleep specialist.

1.To prevent yourself from sleeping too much on weekends, you should________.

A. go lo bed 15 minutes earlier than usual

B. go to bed at usual time

C. go to bed at any time

D. make an adjustment to your bedtime

2.Which of the following makes it easier for you to have a sound sleep?

A. Watching violent programmes before going to bed.

B. Changing your bedtime only a little every day.

C. Using heavy curtains or an eye mask to block light.

D. Completing your workout just before bedtime.

3. The following ways can help fight after-dinner drowsiness EXCEPT_______.

A. making a telephone call

B. doing some washing

C. getting clothes ready for the next day

D. having a rest on the sofa

4. If your sleep problems continue, you’d better_____________

A. move into a new house

WASHINGTON — Money can buy happiness, but only if you spend it on someone else, according to researchers.

    Spending as little as $5 a day on someone else could significantly boost happiness, the team at the University of British Columbia and Harvard Business School found on Thursday.

    Their experiments on more than 630 Americans showed they were measurably happier when they spent money on others --- even if they thought spending the money on themselves would make them happier.

    “We wanted to test our theory that how people spend their money is at least as important as how much money they earn,” said Elizabeth Dunn, a psychologist at the University of British Columbia.

    They asked their 600 volunteers first to rate their general happiness, report their annual income and detail their monthly spending including bills, gifts for themselves, gifts for others and donations to charity.

    “Regardless of how much income each person made, those who spent money on others reported greater happiness, while those who spent more on themselves did not,” Dunn said in a statement.

    “Employees who devoted more of their bonus to pro-social spending experienced greater happiness after receiving the bonus, and the manner in which they spent that bonus was a more important predictor of their happiness than the size of the bonus itself,” they wrote in their report, published in the journal Science.

    “Finally, participants who were randomly (隨機(jī)地) required to spend money on others experienced greater happiness than those required to spend money on themselves,” they said.

    They gave their volunteers $5 or $20 and half got clear instructions on how to spend it. Those who spent the money on someone or something else reported feeling happier about it.

    “These findings suggest that very minor adjustment in spending allocations (分配) --- as little as $5 --- may be enough to produce real gains in happiness on a given day,” Dunn said.

    This could also explain why people are no happier even though US society is richer.

    “Indeed, although real incomes have increased dramatically in recent decades, happiness levels have remained largely flat within developed countries across time,” they wrote.

1.

 Dune’s experiment on 630 Americans was to ________.

    A. help people make careful plans for their money                 B. encourage people to be generous to others

    C. see how to spend money is important to happiness               D. test whether $5 is enough to buy happiness

2.

What can we conclude according to the experiment?

    A. Happiness largely depends on the size of your bonus money.

    B. Happiness, as a matter of fact, has nothing to do with money.

    C. The more money you give away, the happier person you will be.

    D. Spending money for the good of society will make you happier.

3.

How many different ways are used by the researchers to test their theory?

    A. Two.               B. Three.             C. Four.            D. Five.

 The last sentence of the passage means _______.
