If you want to learn anything at school, you need to listen to your teachers. Unfortunately, millions of kids can’t hear what their teachers are saying. And it’s not because these students are goofing off. Often, it’s the room’s fault. Building architecture and building design can create echo(回声)-filled classrooms that make hearing difficult.
Children with hearing impairments（损伤）suffer most from noisy classrooms. They sometimes can’t hear questions that other students ask in class. Compared with kids with healthy hearing, they have a harder time picking up new vocabulary words by hearing them in talking.
Even kids with normal hearing have a harder time in the classroom when there’s too much noise. Younger children in particular have trouble separating important sounds – like a teacher’s voice – from background noise. Kids with learning disabilities and speech impediments（障碍）and kids for whom English is a second language also have a harder time learning in noisy situations.
In recent years, scientists who study sound have been asking schools to reduce background noise, which may include loud air-conditioners and pipes. They’re also targeting outdoor noises, such as highway traffic. Noise reduction is a big deal. Why? Because quieter classrooms might make you smarter by letting you hear your lessons better.
“It’s so obvious that we should have quiet rooms that allow for access to the lesson,” says Dan Ostergren, a hearing scientist. “Sometimes it surprises me that we spend so much time discussing this topic. I just want to go. Why is this hard for anyone to grasp?” The underlined part “goofing off” in the first paragraph can be replaced by “ ”.

The United States is already one year into a depression That was the news this week from the Na-tional Bureau of Economic Research. The downturn is the longest since a depression that began in 1981and lasted sixteen months.
Economists generally wait for production to shrink for six months in a row before they declare a re-cession. But the bureau, a private group, uses a wider set of information to measure the economy. Thenews only confirmed what many people already knew: that the world's largest economy is weak and maynot recover soon.
Worsening conclitions have led to a big drop in spending, especially on costly products like new cars. Even Japanese automaker Toyota saw its sales fall thirty - four percent in the United States in November from a year ago.
The heads of Chrysler, Ford and General Motors retumed to Congress this week to again ask for federal aid. Congressional leaders denounced(指责) them two weeks ago after they came in private jets with no clear plans for saving their industry. This time, the chiefs drove to Washington in fuel- saving hybrid vehicles. And their companies presented detailed restructuring plans. The reguest for aid has risen from twenty-five billion dollars two weeks ago to thirty-four billion in loans and credit lines.
G.M. wants almost half of that, and says it needs four billion dollars this month. It warned that without support it cannot continue to operate.
Ford is in a better position, But the sharing of suppliers means it could be affected if G.M. or
Chrysler fails. Ford is asking for a nine billion dollar credit line in case it needs it.
Chrysler is the smallest and most trouble of America's Big Three. It says it needs a seven billion dollar loan by the end of the month.
Two days of congressional hearings began Thursday in the Senate Banking Committee. The chairman, Democrat Chris Dodd, said he would support helping the automakers for the good of the economy.
But the committee's top Republican, Richard Shelby, continued to express opposition to a bailout(贿政援助）．
A main root of the world financial crisis is the weak housing market in the United States. The Trea-sury Department has been under pressure to help troubled homeowners. Now comes news that the depart-ment is developing a plan aimed at reducing interest rates on mortgage loans(汽车贷款) for some buyers of homes. That could be good for homeowners trying to sell.From the first two paragraphs, we know .
| A．the United States is expected to recover soon |
| B．the depression has lasted more than 16 months |
| C．the depression is much more severe than expected |
| D．the depression will last no more than 6 months |
Why were the automakers refused for federal aid two weeks ago?
| A．Because the government had no extra money to help. |
| B．Because they didn't have a ciear plan to save their industry. |
| C．Because they had wasted too much on costly new cars. |
| D．Because they had enough money to save their industry. |
Which of the following is asking for the largest federal aide
| A．G.M. | B．Toyota. | C．Chrysler. | D．Ford. |

One Tuesday evening in the beginning of the fall 1996 semester at Shippensburg University, sirens(警笛) sounded. These sirens were not in celebration; they were a cry to the university that something was wrong. A house, only one block away, was on fire. Nine of the university's students lived there.
From the minute the word got out that help was needed, it seemed like everyone showed up. The victims of the fire were offered endless invitations for housing for the night. The very next day, everyone got into gear to do their part in helping them. Flyers (小传单) were posted with items that were immediately needed, just to get these students through this next couple of days. Boxes for donations and money jars were placed in every residence hall（学生宿舍）．
As a residence director，I went before the students in my hall to ask them to do what they could. I knew that college students don't have much, but I asked them to do their best: “Every little bit will help." I really didn't think they could do much. I was proved wrong.
At the hall council meeting the night after the fire, my residents decided to have a wing competition, where each wing of the building would team up to see who could bring In the most donations. I announced that the wing who won would receive a free pizza party.
Thursday evening we announced over the PA system that we were beginning the wing competition. Within minutes, the place exploded. The single large box that I had placed in the lobby (太厅) was over-flowing. We quickly grabbed more boxes, and we watched in amazement as they, too, filled to the brim. Members of the resident assistant staff and I began to count the items. I was astonished by what I saw, and I was inspired by these kids.
When we came to the final tally（得分）, the winners turned to me and announced that they would like to donate their winnings as well. They wanted the victims of the fire to have their pizza party.
Tears welled up in my eyes. I had watched these students jump to action, work tirelessly and donate all that they could. And then, as if that were not enough, they handed over their reward’s was touched and so very proud of them.The writer mainly wanted to by the story.

Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes.Scientists have found the gene that determines skin color.
The gene comes in two versions, one of which is found in 99 per cent of Europeans.The other is found in 93 t0 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark - striped zebrafish(斑马鱼) to uniform gold by inserting a version of the pigment(色素) gene into a young fish.As with humans, zebrafish skin color is deter-mined by pigment cells，which contain melanin(黑色素).The number, size and darkness of melanin perpigment cell determine skin color.
It appears that, like the golden zebrafish, light - skinned Europeans also have a mutation (变异) in the gene for melanin production.This results in less pigrnented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in hu-man ancl zebrafish genes.
Humans acquired dark skin in Africa about l.5 million years ago to protect bodies from ultra - violetrays of the sun. which can cause skin cancer.
But when modem humans leave Africa to live in northem latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer.lt also could lead to research in-to ways to change skin color without damaging it like chemical treatment did on Michael Jackson.Scientists have done an experiment on a dark -striped zebrafish in order to
| A．fincl the different genes o humans' |
| B．prove the humans' skin color is determined by the pigment gene |
| C．find out the reason why the Africans' skin color is dark |
| D．fincl out the ways of changing people's skin color |
lt can be inferred from the passage that .
| A．nowadays people who want to change their skin color have to suffer 8 lot from the damage caused by the chemical treatment |
| B．Europeans and Africans have the same gene |
| C．the new discovery could help to find medical treatments for skin cancer |
| D．there are two kinds of genes |
The passage mainly tells us that .
| A．scientists have found out that people's skin color is determined by the gene |
| B．the new discovery could lead to research into ways to change skin color safely |
| C．pop king Michael Jackson often changed his skin color as he liked |
| D．people can not change their skin color without any pain |
The reason why Europeans are light - skinned is probably that .
| A．they are bom light - skinned people |
| B．light - skinned Europeans have mutation in the gene for melanin production |
| C．they have fewer activities outside |
| D．they pay much attention to protecting their skin |
The writer's attitude towarcls the discovery is .
| A．neutral | B．negative | C．indifferent | D．positive |
Moral science is taught as a subject in most schools but with little effect. Perhaps part of the problem lies in the fact that morality is not a science, strictly speaking. It is too much of a social phenomenon, and also has too much of the personal and subjective things mixed within. Besides, morality itself changes with generations. So it is impossible to be defined in a textbook.
I remember sitting through forty minutes of moral lessons, which told stories about little children who never told lies and were rewarded for their goodness. It had little effect and left no impression on me, though.
If moral science has to be taught as a subject in schools, it needs a participatory(参与其中的) approach. When you tell a child about morals, you also have to deal with social norms（规范）and cultural differences. You have to explain that morality can be subjective, and be able to co-exist in society. You will probably have to refer to the morals of the present time.
The best way to tell a child how to live is to show him what is valued. If a child likes his friend, you have to make the child think about why. Once the child notices and recognizes goodness in others, he or she is likely to develop it as well.
In fact, children learn most of their morals by watching people around them. They absorb behavior patterns from teachers and older students. They watch to see what is rewarded and who is punished. They learn on the sports field and through social work. Moral science lessons should simply consist of letting them live and interact, and watch you support correct values and reward good behavior. Which is NOT the reason that moral science is taught in schools but with little effect?
| A．Morality doesn’t strictly belong to a science |
| B．Morality is more like a social phenomenon. |
| C．Different generations have different moral ideas. |
| D．Morality can’t be written down in textbooks. |
The author describes his own experience of having moral lessons in order to _____.
| A．explain telling lies is not moral for little children. |
| B．advise people should be rewarded for their goodness. |
| C．prove moral lessons in schools have little effect. |
| D．show he has no opinions about moral science. |
When you tell a child about morals, you should________.
| A．teach him to share personal moral ideas with others |
| B．tell him about social norms and cultural differences |
| C．explain that nobody can influence his moral ideas. |
| D．say that the present morals are likely to be changed. |
What is the last paragraph mainly about?
| A．The best way of teaching children about morals. |
| B．The value of teachers’ setting a good example |
| C．The influence of people’s behavior on morals. |
| D．The importance of rewarding good behavior. |
