As many as one in five US teenagers have some degree of hearing loss, according to researchers. They say the problem is growing.
“Teenagers really don’t pay attention to how much noise they are exposed to(接觸),” Josef Shargorodsky of Brigham and Women’s Hospital in Boston told Reuters. “Often people won’t notice it, but even very little hearing loss may influence language development,” said Shargorodsky, one of the researchers.
The study compared surveys from the early 1990s and the mid-2000s. Each included a few thousand teenagers. In the first survey, about 15 percent of teenagers had some degree of hearing loss. Some 15 years later, that number had risen by a third, to nearly 20 percent.
“This certainly is big news,” said Alison Grimes, an ear doctor. “Hearing loss is very common in old people,” Grimes said, but she added that it was worrying to see it happen in the younger age group.
In babies and young children, hearing problems are known to slow language development. The science is less clear for teenagers, but it is easy to imagine how being hard of hearing could influence learning, said Grimes.
The reasons for the rise are still unclear. When researchers asked teenagers about noise exposure – on the job, at school or from activities, for example – the teenagers didn’t report any change. But Shargorodsky said that might not be true. “We know from before that it is difficult to ask this age group about noise exposure – they underestimate it.” Few people would call it noise when they listen to music on their MP3 player, for example. “There is a difference between what we think is loud and what is harmful to the ear,” said Grimes.
Although it’s not clear that the MP3 players cause teenagers’ hearing loss, Grimes said it was still a good idea to turn down the sound and take short breaks from listening.
小題1:The writer advises teenagers __________.
A．to turn the sound down
B．to stop using MP3 players
C．to be clear about the problem
D．to report the change in hearing loss
小題2:The underlined sentence “they underestimate it” means __________.
A．their love for music prevent them realizing the harm
B．their hearing loss is happening without being noticed
C．they think music can be taken as noise to some degree
D．they think it’s harmful sometimes although it’s not loud
小題3:Which of the following is true according to the passage?
A．Hearing loss may lead to slow language development.
B．Hearing loss in old people is as common as in young people.
C．Researchers have already found some causes of hearing loss.
D．Teenagers know MP3 is harmful, but they can’t stop listening to it.
小題4:What is the best title for the passage?
A．A word short and simpleB．A report by teenagers
C．A message loud and clearD．A letter from MP3 users

小題1:A
小題2:B
小題3:A
小題4:C

小題1:細(xì)節(jié)理解題。結(jié)合Grimes said it was still a good idea to turn down the sound and take short breaks from listening可知答案。

科目：高中英語 來源：不詳 題型：閱讀理解

Almost a decade ago, the federal government dropped $10 million for an Earth-monitoring satellite that never made it into space. Today it sits in a closet in Maryland. Cost to taxpayers for storing it: $1 million a year. And that's just what's hiding in one closet. Who knows what's in the rest of them?
Because we think the government should be held to at least the same standards as a publicly traded company, and because as taxpayers, we're America's shareholders, we performed an audit （財(cái)務(wù)檢查）of sorts of the federal books. We're not economists, but we do have common sense. We tried to get help from Congressional staffers from both parties, as well as various watchdog groups and agencies. In the end, we found that the federal government wastes nearly $1 trillion every year.
That's roughly equal to the amount collected annually by the Internal Revenue Service in personal income taxes. Put another way, it's also equal to about one-third of the country's $2.9 trillion total annual budget. And reclaiming that lost trillion could help wipe out the country's annual budget deficit（赤字）, improve education, and provide health insurance for those who don't have it.
So how do you define "waste"? David Walker of the Government Accountability Office (GAO), a federal watchdog agency, calls it "the government's failure to give taxpayers the most for their money." For our part, we used the kind of household test you would use on a piece of meat sitting in your refrigerator: If it smells rotten, it's waste. Our government regularly pays for products and services it never gets, wildly overpays companies to do things it could do more cheaply itself, loses money outright due to lax（不嚴(yán)格的）accounting and oversight, and spends money randomly on unnecessary programs.
How exactly does the federal government waste your hard-earned tax dollars? We've identified what we consider ten of the worst ways.
小題1:The underlined sentence in Paragraph1 really means        .
A．there are many other closetsB．there are some other satellites
C．there is something else in the closetsD．the waste may be quite amazing
小題2:Which of the following can best describe the feeling of the author?
A．Annoyed.B．Calm.C．Surprised.D．Not concerned.
小題3:Which of the following statements may be right?
A．The country’s annual budget is usually decided by the public.
B．The government failed in launching the satellite.
C．The government is only wasting money in space experiments.
D．The amount collected annually in personal income taxes is equal to the country’s budget.
小題4:The best title for the passage would be        .
A．Protecting Our Rights!
B．Our Country Is In Danger!
C．The Government Is Wasting Our Tax Dollars!
D．How to Prevent Government from Wasting Money!
小題5:What might be talked about if the passage is continued?
A．The government’s taking some steps to stop wasting taxes.
B．Presenting people’s feelings against the government’s wasting taxes.
C．Giving suggestion to help the government solve the financial problem.
D．Listing how the government is wasting taxes.

“Have a nice day!” may be a pleasant gesture or a meaningless expression. When my friend Maxie says “have a nice day” with a smile, I know she sincerely cares about what happens to me. I feel loved and secure since another person cares about me and wishes me well.
“Have a nice day. Next!” this version of the expression is spoken by a salesgirl at the supermarket who is rushing me and my groceries out of the door. The words come out in the same tone (腔調(diào))with a fixed procedure. They are spoken at me, not to me. Obviously, the concern for my day and everyone else’s is the management’s attempt to increase business.
The expression is one of those behaviors that help people get along with each other. Sometimes it indicates the end of a meeting. As soon as you hear it, you know the meeting is at an end. Sometimes the expression saves us when we don’t know what to say. “oh, you just had a tooth out? I’m terribly sorry, but have a nice day.”
The expression can be pleasant. If a stranger says “Have a nice day!” to you, you may find it heart-warming because someone you don’t know has tried to be nice to you.
Although the use of the expression is an insincere, meaningless social custom at times, there is nothing wrong with the sentence except that it is a little uninteresting. The salesgirl, the waitress, the teacher, and all the countless others who speak it without thinking may not really care about my day. But in a strange and comfortable way, it’s nice to know they care enough to pretend they care when they really don’t care all that much. While the expression may not often be sincere, it is always spoken. The point is that people say it all the time when they like.
小題1:How does the author understand Maxie’s word?
A．Maxie shows her anxiety to the author.
B．Maxie really wishes the author a good day.
C．Maxie encourages the author to stay happy.
D．Maxie really worries about the author’s security.
小題2:What does the underlined sentence in Paragraph 2 mean?
A．The salesgirl is rude.B．The salesgirl is bored.
C．The salesgirl cares about me.D．The salesgirl says the words as a routine.
小題3:By saying “Have a nice day,” a stranger may______.
A．try to be polite to youB．express respects to you
C．give his blessing to youD．share his pleasure with you.
小題4:According to the last paragraph, people say “Have a good day” __________
A．sincerelyB．a(chǎn)s thanksC．a(chǎn)s a habitD．encouragingly
小題5:What is the best title of the passage?
A．Have a Nice Day---- a Social Custom
B．Have a Nice Day----- a pleasant Gesture
C．Have a Nice Day----- a heart-warming Greeting
D．Have a Nice Day----- a polite ending of a Conversation

In my opinion, there is only one legitimate (合法的) handgun sport and that is aim practice. It is practiced at objects which are properly monitored and usually quite safe. Only certain handguns are true “sporting weapons”, seen as such by the sport’s lovers.
On the other hand, shooting at tin cans and other small objects in one’s backyard is not and should not be considered a serious sport. When uncontrolled, it can be a very dangerous practice.
Some opponents (反對(duì)者) of handgun control have stated that we are out to stop all hunting and that controlling the handgun would severely affect hunting. That is simply untrue. Handgun control would in no way limit the freedom of the true hunter. Few if any hunters consider the handgun an effective hunting weapon.
There are a few hunters who do hunt with handguns, but most states place restrictions (限制) on the type of guns that can be used in hunting, the reason is that killing of game should be done in as humane (人道的) a way as possible. Some small handguns are more likely to wound the animal rather than kill it at once. Only long guns, rifles and shotguns are effective arms of hunting.
People must understand that handguns and hunters are separate matters. Because most of the hunters use a rifle or shotgun, there is no reason why their search for game and sport should be affected by handgun control. Mixing the anti-hunting matter with the handgun matter confuses the killing of animals with killing of people.
小題1:In the writer’s opinion, people should use handguns only when           .
A．hunters shoot at animals
B．they aim at a criminal
C．objects are under control
D．objects are only small tin cans in the backyard
小題2:According to the writer, hunting is not affected by handgun control because         .
A．hunters can use knives rather than guns to hunt animals
B．state government encourages hunters to use other guns
C．nobody cares what weapons are used to kill animals
D．most hunters use rifles rather than handguns
小題3:This passage mainly talks about           .
A．the relation between hunting and handgun control
B．the importance of aim practice
C．how handgun control affects hunting
D．different types of guns used in hunting

When a rather dirty, poorly dressed person kneels at your feet and puts out his hands to beg for a few coins, do you hurry on, not knowing what to do, or do you feel sad and hurriedly hand over some money? What should our attitude to beggars be? There can be no question that the world is full of terribly sad stories. It must be terrible to have no idea where our next meal is going to come from. It seems cruel not to give some money to beggars.
Certainly, most of the world’s great religions order us to be open-hearted and share what we have with those less fortunate than ourselves. But has the world changed? Maybe what was    morally（道德方面）right in the old days, when one knew exactly who in the village had suffered  misfortune and needed help, is no longer the best idea. Quite a few people will not give to beggars.     Let us look at their arguments.
First, some believe that many city beggars dress up on purpose to look pitiable and actually make a good living from begging. Giving to beggars only encourages this sort of evil（惡行）.                           
Secondly, there is the worry that the money you give will be spent on beer, wine or drugs.
Thirdly, there is the opinion that there is no real excuse for begging. One might be poor, but that is no reason for losing one’s sense of pride and self-dependence.
There is an opinion that the problem should be dealt with by the government rather than ordinary people. Some people think the local government department should help the beggars
It is hard to come to any final conclusion: there are various cases and we must deal with them differently. A few coins can save a life in some situations, and even if the money is wasted, that does not take away the moral goodness of the giver. 
小題1:What is mainly discussed in the passage?
A．Moral deeds of people.
B．Arguments on giving to beggars.
C．Moral goodness of the giver.
D．Religious activities of the church.
小題2:What can we infer from the underlined sentence “But has the world changed?” in Para.2 ?
A．People no longer know who suffers misfortune in the village.
B．Some people will not do what was morally right in the past.
C．We don’t meet with those who need help any more.
D．Now it is the government’s duty to help the beggars.
小題3:Which of the following is NOT mentioned in the passage?
A．Some people dress up to pretend to be beggars.
B．Some beggars have no excuse for begging.
C．Some beggars use the money to buy drugs.
D．Some beggars need money for their children’s schooling.
小題4:In the last paragraph, the writer thinks that it is hard to come to any final conclusion, because________.
A．there is so much money wasted
B．there are so many beggars
C．the cases can be so different
D．there are so many different arguments

The Loss of Innocence（純真）
Innocence is such a precious gift. It’s explained as freedom from guilt or wrong doing. Just imagine never having to worry about anything and having a guilt-free mind. Some people wish to save this kind of innocence from being lost from childhood to adulthood.
What would the world be like if innocence were never lost? One way it would benefit humanity is the lack of hatred （仇恨） among the world. During youth, there may be an occasional argument, even a little physical fight, but nothing like firing a handgun at a fellow human being. And children are blind towards the racial differences of others. A kid will hang out with any other kid. It is the lack of innocence and the ignorance we learn from adults that influence children otherwise. Another benefit is the constant desire for fun and adventure. With very little if any time at all for fun, the adventurous mind is lost in time with the responsibilities placed upon adults. If innocence were kept alive, these ambitions would never depart from our lives.
However, other people actually hate the idea of innocence lasting for ever. They feel that the lack of organization and mental power of those with innocence would cause extremely destructive consequences to society in general. A large number of individuals would never have the urge to learn, work, and act upon the necessary needs for humanity to survive. Without a proper education which is usually provided by those who no longer live in a world of innocence, people would not have the desire to succeed, get a good job in life, or provide income for their families, which would hurt the lives of children.
The lack of a good education and career would also harm the economy. As long as innocence is kept alive, no one would be terribly angry at the lack of effort people put out in the workplace, resulting in a strong decline（減少） in production and quality of needed goods.
Maybe it is wrong in wanting to save innocence. It sure is a nice thought, though. Perhaps innocence was meant to be lost. It was god's will to make things the way they are, and there is a good purpose for everything. All that remains to be said about innocence is to enjoy it while it lasts.
小題1:The author believes that the loss of innocence in adulthood should be______.
A．a(chǎn)voidedB．criticizedC．a(chǎn)cceptedD．encouraged
小題2:Lifelong innocence would be beneficial to society in that__________.
A．proper education would be provided
B．there would be no racial discrimination
C．there would be more happy families
D．people would realize their childhood dreams
小題3: According to the author, people with innocence can hurt the economy with their lack of____ .
A．motivational will
B．mental ability
C．a(chǎn)dventurous ambitions
D．needed goods

Endangered languages are languages that wouldn’t exist any longer, much like endangered species of plants or animals. Languages are considered to be endangered when parents are no longer teaching the language to their children and are not using it actively in everyday life. A language is considered to nearly disappear when it is spoken by only a few elderly native speakers.
The world faces enormous challenges in order to protect different kinds of languages. Of the more than 6,912 languages, half may be in danger of disappearing in the next several decades.
It is caused by many reasons: small numbers of speakers, the regular use of other languages, attitudes towards their languages, moving of the younger population, government policies, and languages used in education and so on. A language may lack important things such as a body of literature, and people who read and write it. A language may also lack prestige (聲望) and support of its speakers.
The survival of a language is also threatened when speakers move to other areas where different languages are spoken, or when government policies improve the use of a specific language in school, official business and the media. These situations encourage people to learn the wider-known language and may cause them, especially the young, to stop using their mother tongue. Often those speaking lesser-known languages will choose to learn a more prestigious language with the hope of greater economic opportunities. Most of the world’s parents are teaching their children English, French, Spanish, Chinese, Arabic, Russian or some other main languages instead of their own languages for social and economic reasons.
小題1:What’s the main idea of this passage?
A．Languages in the world.
B．Reasons why languages become endangered.
C．What an endangered language is.
D．Languages spoken by few speakers.
小題2:About ________languages will probably disappear in this century according to the passage.
A．more than 6,912B．more than 3,456C．6,912D．less than 3,456
小題3:Which of the following best shows the structure of the passage?
①=Paragraph1   ②=Paragraph2  ③=Paragraph3  ④=Paragraph4

小題4:We can infer that the best way to maintain an endangered language is to _________.
A．forbid the speakers to move about
B．pass laws to protect the language
C．raise the salaries of the people who speak the language
D．teach the language to young children and encourage people to speak it often
小題5:All of the following about languages are true EXCEPT __________.
A．many languages will be probably endangered in this century
B．government policies have a big effect on languages
C．the endangered language is a language that is spoken by a few people
D．languages are related to their speakers’ social and economic position
