第一節(jié)   閱讀表達(dá):

閱讀下面的短文,并根據(jù)短文后的要求答題(請注意問題后的詞數(shù)要求。答案寫在答卷紙上)

Learning to save money when you're young is an important lesson. All good lessons and habits begin early, and saving is a skill that everyone needs. Many people—adults included—do not have a good sense of saving for the long run.

I have been lucky to learn this lesson early because I have had a grass-cutting business since I was 10 years old. Of the money I make I spend about 10 percent and save the other 90.

Making sure you save and don't spend too much is a good way to build up wealth. I have put my earnings in a bank. Many teens I know spend all the money they earn so it never has a chance to grow. Young people should realize that their teenage years are a great time to begin saving.

At high school many parents pay for almost everything, so your expenses can be small. If you have a job, you should have fun with some of the money. But you should also save some so that it will grow. Then you can begin planning for your future. When you spend money, you not only lose that money, but also lose the interest you could have earned by saving it.

After high school, college is expensive and then "real" life begins, with expenses such as food and rent. If you can hold onto a good percentage of the money you earn as a teen, going to college and buying a house will be much easier. ________________, the more time the money has to grow. If you are in your thirties without any savings, you will always have to struggle. The earlier you begin saving, the easier it is to create a nest egg.

Later in life it can be hard to start saving because general costs of living are more expensive and you may only have enough to pay your bills. If you want to buy a house and have a family, you need money to start with, which comes from saving.

Many say money cannot make you happy, and this is true. But money can help you to lead a secure life.

Saving early will mean you will have to work for fewer years when you are older. It will also allow you to spend time doing the things that you want to do.

In addition to this, it will mean you can live the way you want to without worrying.

As long as you save early, you’ll do less work to live well at your old age.

閱讀下面的短文,并根據(jù)短文后的要求答題。(請注意問題后的詞數(shù)要求)

[1]It seems parents have long been right. Going to bed early is key to getting enough sleep and helping adolescents feel on top of the world, a new study reported.

[2]A lack of sleep among youngsters may trigger depression and suicidal thoughts, according to the study by the Columbia University Medical Center.

[3]"Our results are consistent with the theory that inadequate sleep is a risk factor for depression, working with other risk and protective factors through multiple possible causal ways to the development of this mood disorder," said lead author James Gangwisch.

[4]"Adequate quality sleep could therefore be a preventative measure against depression and a treatment for depression," he added in the study published in the Friday issue of Sleep magazine.

[5]The study followed the nightly habits of some 15,659 college and high-school students, and found those who consistently turned in after midnight had a 24 percent higher risk of depression than those who                     before 10:00 pm. Night owls also ran a 20 percent higher risk of battling suicidal thoughts, the study added.

[6]The American Academy of Sleep Medicine recommends that adolescents should sleep at least nine hours or more a night. Those who were tucked in before 10:00 pm reported they slept on average about eight hours and 10 minutes. But that amount of sleep dropped significantly for those in bed after midnight.

[7]And adolescents who slept five hours or less a night were 71 percent more likely to suffer depression and 48 percent more at risk of becoming suicidal, the study said.

[8]"It is a common perception and societal expectation that adolescents do not need as much sleep as pre-adolescents. Yet studies suggest that adolescents may actually require more sleep." said Gangwisch.

[9]"Studies have found that adolescents do not go to bed early enough to make up for earlier school start time. And transitions to earlier school start times have been shown to be associated with significant sleep deprivation."

76. What’s the main idea of the passage? (Please answer within 8 words)

77. What theory are the study results similar to? (Please answer within 20 words)

78. Fill in the blank in Paragraph 5 with proper words. (Please answer within 6 words)

79. Which sentence in the text is the closest in meaning to the following one?

It’s widely accepted that the youngsters needn’t sleep as much as the child.

80. Translate the underlined sentence in Paragraph 9 into Chinese.

第一節(jié) 閱讀表達(dá)(共5小題;每小題3分,滿分15分)

閱讀下面短文,按要求完成76—80題。(請注意問題后的字?jǐn)?shù)要求)。

Electronic devices(裝置) are changing the way people listen to music. But studies show the devices may be causing hearing loss in many people. Some experts say people may be playing them too loud and too long. And experts say sound levels on these devices need to be set lower.

Researchers did a study with three hundred high school students and one thousand adults. They were asked about their use of portable music devices. Forty percent of the students and adults said they set the sound levels at high on their players. But students were twice more likely to play the music at a very loud volume(音量). More than half of the students said they would probably not limit their listening time.

The study found that more than half of the students and less than forty percent of the adults had at least one kind of hearing loss. Some reported difficulty hearing parts of a discussion between two people. Others said they had to raise volume controls on a television or radio to hear it better. And, some experienced ringing in their ears or other noises.

Hearing experts say part of the problem is the listening equipment people are using. They say large earphones that cover the whole ear are probably safer than the smaller earbuds(耳塞) that come with most music players. Hearing loss may not be obvious for years, however, once it happens, there is few chance of curing. About thirty million Americans have some hearing loss. One third of them lost their hearing as a result of loud noises.

The American Speech-language-Hearing Association is working with companies and government officials on setting rules for use of portable music devices. The group says the best way to protect your hearing is to _______, limit listening time and use earphones that block out foreign noises.
