The World Health Organization recently reported that the number of cases of tuberculosis(TB) has been abating since 2006 . Also, fewer people are dying from TB. But a study by researchers at the University of California, San Francisco, says smoking could threaten this progress.
Nearly twenty percent of all people use tobacco, and millions of non-smokers get sick from breathing the smoke. The new study predicts that smoking will produce an additional thirty-four million TB deaths by 2024.
Efforts to control the spread of TB have mainly focused on finding and treating infections. Fewer efforts have been made to understand the causes. Dr Anthony Fauci is the director of the United States National Institute of Allergy and Infectious diseases. He said, “Despite our control efforts, we still have more than a million people each year dying from TB and millions of people  getting infected; we realize it’s still a very important problem. So we have to do the practical thing and we have to do the fundamental research things at the same time. ”
Smoking does not cause TB; bacteria cause the infection. But the study says smoking affects the nervous system in a way that makes an inactive case of TB more likely to develop into an active one. Stanton Glantz is the director of the University of California’s Centre for Tobacco Control Research and Education and an author of the new study. He says it shows that TB cannot be controlled unless tobacco use is controlled.  He said, “It increases the number of people who will get TB by about seven percent.”
The study is described as the first to identify a direct link between tobacco use and rates of TB infection and death. Professor Glantz says the results should guide those creating health policies and TB control efforts. He said, “If you want to control the infectious disease of TB, you have to control the tobacco industry and the tobacco industry’s efforts to increase tobacco use, particularly in developing countries where TB is a big problem.”
What would be the beat title for this passage?

A.Scientists try to find the causes of TB deaths.
B.Study shows smoking is harmful to our health.
C.Study links smoking to millions of TB deaths.
D.Scientists pay more attention to TB deaths than before.

A.Responding B.Surviving. C.Rising. D.Falling.

What would Dr Anthony Fauci probably agree with?

A.More efforts are needed to find the causes of TB infections.
B.TB infections are no longer a serious problem.
C.Few efforts have been put into the work of treating TB infections.
D.The practical and the fundamental research cannot be done together at present.

It is implied in the passage that ____________.

A.it is not very hard to control TB
B.smoking indirectly leads to TB
C.an inactive case of TB is deadly
D.people cannot blame smoking for TB

Jobs and work do much more than most of us realize to provide happiness and contentment.We're all used to thinking that work provides the material things of life—the goods and services that make our modern civilization possible.But we are much less conscious of the degree to which work provides the more important psychological wellbeing that can make the difference between a full and an empty life.
Historically,work has been associated with slavery and sin (罪恶)and punishment.And in our own day we are used to bearing traditional complaints.Against this background,it may well come as a surprise to learn that not only psychologists but other behavioral scientists have come to accept the positive contribution of work to the individual's happiness and sense of personal achievement.Work is more than a necessity for most human beings;it is the focus of their lives,the source of their identity and creativity.
Rather than a punishment of a burden,work is the opportunity to realize one's potential.And the opposite is true,too.For large numbers of people,the absence of work is harmful to their health.Retirement often brings many problems surrounding the “What do I do with myself?”question,even though there may be no financial cares.Large numbers of people regularly get headaches and other illnesses on weekends when they don't have their jobs to go to,and must take care of themselves.It has been observed that unemployment,quite apart from financial pressures,brings enormous psychological troubles and that many individuals'conditions become worse rapidly when jobless.
But why?Why should work be such a significant source of human satisfaction?A good share of the answer rests in the kind of pride that is stimulated by the job,by the activity of accomplishing.

When 19yearold Sophia Giorgi said she was thinking of volunteering to help the MakeAWish Foundation(基金会), nobody understood what she was talking about. But Sophia knew just how important MakeAWish could be because this special organization had helped to make a dream come true for one of her best friends. We were interested in finding out more, so we went along to meet Sophia and listen to what she had to say.
Sophia told us that MakeAWish is a worldwide organization that started in the United States in 1980. “It's a charity(慈善机构) that helps children who have got very serious illnesses. MakeAWish helps children feel happy even though they are sick, by making their wishes and dreams come true,” Sophia explained.
We asked Sophia how MakeAWish had first started. She said it had all begun with a very sick young boy called Chris, who had been dreaming for a long time of becoming a policeman. Sophia said lots of people had wanted to find a way to make Chris's dream come true—so, with everybody's help, Chris, only seven years old at the time, had been a “policeman” for a day. “When people saw how delighted Chris was when his dream came true, they decided to try and help other sick children too, and that was the beginning of MakeAWish,” explained Sophia.
Sophia also told us the Foundation tries to give children and their families a special, happy time. A MakeAWish volunteer visits the families and asks the children what they would wish for if they could have anything in the world. Sophia said the volunteers were important because they were the ones who helped to make the wishes come true. They do this either by providing things that are necessary, or by raising money or helping out in whatever way they can.
Sophia found out about MakeAWish because her best friend had ________.

A.benefited from it B.volunteered to help it
C.dreamed about it D.told the author about it

According to Sophia, MakeAWish ________.

A.is an international charity

A.He has been a policeman since he was seven.
B.He gave people the idea of starting MakeAWish.
C.He wanted people to help make his dream come true.
D.He was the first child MakeAWish helped after it had been set up.

Which of the following is true about MakeAWish volunteers?

A.They are important for making wishes come true.
B.They try to help children get over their illnesses.
C.They visit sick children to make them feel special.
D.They provide what is necessary to make MakeAWish popular.

Bad teeth can be painful and even be deadly. Infections of the gums(牙龈) and teeth can release bacteria into the blood system. Those bacteria can increase the chance of a heart attack or stroke and worsen the effects of other diseases. And adults are not the only ones at risk. For example, a 12yearold boy died when a tooth infection spread to his brain in 2007 in Washington. Experts said it might have been prevented had he received the dental care he needed.
Experts say good dental care starts at birth. Breast milk, they say, is the best food for the healthy development of teeth. Breast milk can help slow bacterial growth and acid production in the mouth. But dentists say a baby's gums and early teeth should be cleaned after each feeding by using a cloth with a little warm water. Experts say if you decide to put your baby to sleep with a bottle, give only water.
When baby teeth begin to appear, you can clean them with a wet toothbrush. Dentists say it is important to find soft toothbrushes made especially for babies and to use them very gently. The use of fluoride(氟化物) to protect teeth is common in many parts of the world. For example, it is often added to drinking water supplies. The fluoride mixes with enamel(釉质), the hard surface on teeth, to help prevent holes from forming.
But young children often swallow toothpaste when they brush their teeth. The American Academy of Pediatric Dentistry notes that swallowing fluoridated toothpaste can cause problems. So young children should be carefully watched when they brush their teeth. And only a small amount of fluoridated toothpaste, the size of a pea, should be used.
Parents often wonder what effect finger sucking might have on their baby's teeth. Dental experts generally agree that this is fine early in life. Most children stop sucking their fingers by the age of four. If it continues, experts advise parents to talk to their children's dentists or doctors. Because it could interfere_with the correct development of permanent teeth.
Dentists say children should have their first dental visit at least by the time they are one year old. They say babies should be examined when their first teeth appear—usually at around six months.
According to the passage,what is the function of fluoride?

A.Making the surface on teeth much cleaner.
B.Protecting gums from being infected.
C.Keeping holes on teeth from forming.
D.Slowing down bacterial growth and acid production.

No one knows for sure when advertising first started. It is possible that it grew out of the discovery that some people did certain kinds of work better than others did them. That led to the concept of specialization, which means that people would specialize, or focus, on doing one specific job.
Let's take a man we'll call Mr. Fielder, for example. He did everything connected with farming. He planted seeds, tended the fields, and harvested and sold his crops. At the same time, he did many other jobs on the farm. However, he didn't make the bricks for his house, cut his trees into boards, make the plows(犁), or any of the other hundreds of things a farm needs. Instead, he got them from people who specialized in doing each of those things.
Suppose there was another man we shall call Mr. Plowright. Using what he knew about farming and working with iron, Mr. Plowright invented a plow that made farming easier. Mr. Plowright did not really like farming himself and wanted to specialize in making really good plows. Perhaps, he thought, other farmers will trade what they grow for one of my plows.
How did Mr. Plowright let people know what he was doing? Why, he advertised, of course. First he opened a shop and then he put up a sign outside the shop to attract customers. That sign may have been no more than a plow carved into a piece of wood and a simple arrow pointing to the shop door. It was probably all the information people needed to find Mr. Plowright and his really good plows.
Many historians believe that the first outdoor signs were used about five thousand years ago. Even before most people could read, they understood such signs. Shopkeepers would carve into stone, clay, or wood symbols for the products they had for sale.
A medium, in advertising talk, is the way you communicate your message. You might say that the first medium used in advertising was signs with symbols. The second medium was audio, or sound, although that term is not used exactly in the way we use it today. Originally, just the human voice and maybe some kind of simple instrument, such as a bell, were used to get people's attention.
A crier, in the historical sense, is not someone who weeps easily. It is someone, probably a man, with a voice loud enough to be heard over the other noises of a city. In ancient Egypt, shopkeepers might hire such a person to spread the news about their products. Often this earliest form of advertising involved a newly arrived ship loaded with goods. Perhaps the crier described the goods, explained where they came from, and praised their quality. His job was, in other words, not too different from a TV or radio commercial in today's world.
What probably led to the start of advertising?

A.The discovery of iron.
B.The specialization of labor.
C.The appearance of new jobs.
D.The development of farming techniques.

A.praised his plows in public

There is no question that teenagers need rules, which is often not a difficult thing for parents to give.What can be more challenging is giving teenagers their freedom.It can be difficult to draw the line between the two.However, some issues cannot be changed by discussion and require firm rules.For instance, rules should be established concerning driving the family car.
I will admit that I have no problem coming up with rules.To me they make life easier and they leave no room for questioning.What can be more difficult, however, is giving my teens their freedom.I guess there are really two primary reasons for this.One is that sometimes I am afraid to give them freedom.The second is that I'm not always so sure what the freedom should be.
It helps that I have a husband with whom I can discuss these problems.We talk about them,_give our thoughts and then we come up with an agreement.Sometimes one of us might be more unwilling but we know that there comes a time when we really do have to learn how to let go of the reins(缰绳) a bit.
If we try to make life have nothing but rules, we are more likely to see our teen's rebelling(反抗).They need to know that while we do have certain expectations, we also trust them to begin making their own choices and decisions.How else can they do that unless they are given the space and room to do it?
It's really all about balance and I will be the first to admit that it can be a challenge to carry out.However, it is a necessary part of growing up.Yes, teens definitely need rules but they also need freedom.
According to the first paragraph, it is difficult to decide ________.

A.whether the children need rules
B.whether the children should be given freedom
C.how much freedom should be given to children
D.what issues require nonnegotiable rules

According to the writer, only rules without freedom will make the children ________.

Which of the following is TRUE according to the text?

A.Rules are difficult to make for parents.
B.Rules and freedom are similarly important.
C.We should give children freedom as much as possible.
