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.”

It is easy to see how your hearing is under assault in today’s world. There are so many things to hear, and so many new instruments, like iPods and headphones, which can harm your hearing if used improperly. Keeping the volume(音量)to a reasonable level on an iPod or other portable listening instruments is one of the most important ways to protect your hearing. Another great way to keep your hearing protected is to avoid loud noises whenever possible. There are many loud noises from power tools to machinery, and it is important to avoid these noises as often as possible. When it is not possible to avoid them, keep your hearing protected by using earplugs(耳机).
If you think your hearing may have already been damaged by modern technology, it is important to have your hearing tested by a physician. Only such a professional will be able to measure your level of hearing loss and help you find the best solution to your hearing problem.
For those with hearing issues, the choices have never been greater. There are many excellent hearing aids on the market. Having a hearing aid can be a perfect choice for the young and the old alike, and many people who swore they would never wear a hearing aid find that they love the convenience and quality these instruments represent.
Never let an unimportant thing like vanity(虚荣) get in the way of treating a hearing problem. These days there are hearing aids that are nearly invisible to the naked eye, including a number of models that fit completely inside the ear. If you believe you may be experiencing a problem with your hearing, it is important to have it checked out, and to take the right measures to protect your ears. In many cases, this treatment will be as simple as wearing earplugs. Taking care of your ears is of great importance. After all, you only get one set of ears.

A.the causes of hearing loss |
B.the importance of hearing |
C.how to cure hearing problems |

How do people climb the wall? To climb,you need special shoes and a harness(保护带)around your chest to hold you. There are ropes(绳索)tied to your harness. The ropes hold you in place so that you don’t fall. A beginner’s wall is usually about 15 feet high,and you climb straight up. There are small pieces of metal that stick out for you to stand on and hold on to. Sometimes it’s easy to see the new piece of metal. Sometimes, it’s not. The most difficult part is to control your fear. It’s normal for humans to be afraid of falling, so it’s difficult not to feel fear. But when you move away from the wall,the harness and the ropes hold you,and you begin to feel safe. You move slowly until you reach the top.
Climbing attracts people because it’s good exercise for almost everyone. You use your whole body,especially your arms and legs. This sport gives your body a complete workout. When you climb,both your mind and your body can become stronger.

David Belle, a young Frenchman, developed parkour in the 1990s. His father"s experiences as a fireman as well as an acrobat(杂技演员)influenced him a lot. His childhood friend, Sebastien Foucan, is the actor in the movie Casino Royale with his parkour performance. Foucan is thought to have developed free-running, which is a more artistic and skillful type of parkour. David belle traveled to India and said one way he trained was by watching a physical one. The aim is to become so skillful, and it is almost unnecessary for you to think about the different actions in running through a path full of barriers(障碍物).
Parkour is not exactly a sport. It is not developed fro competition. It is more about learning to control mind and body in difficult situations. There are many basic movements in parkour. One example is where practicers swing through the narrow space between two bars while keeping their body level with the ground. This is called the underbar. Other movements are the tic-tac and the kong vault jump. Skillful practicers seem to get out of control of gravity.
The popularity has spread largely because of parkour videos and organizations on the Internet. And if you search on the Web, you will find parkour groups performing their skills near you.

If health issues arise from cell phone use, the possible effects are huge. Voice calls - Americans chat on cell phones 2.26 trillion(万亿)minutes annually - earn $109 billion for the wireless carriers.
Devra Davis, an expert who has worked for the University of Pittsburgh, has published a book about cell phone radiation, “Disconnect.” The book surveys scientific research and concludes the question is not settled.
Brain cancer is a concern that Ms. Davis examines. Over all, there has not been an increase in its incidence since cell phones arrived. But the average masks an increase in brain cancer in the 20-to-29 age group and a drop for the older population.
“Most cancers have multiple causes,” she says, but she points to laboratory research that suggests low-energy radiation could damage cells that could possibly lead to cancer.
Children are more vulnerable(易受伤的)to radiation than adults, Ms. Davis and other scientists point out. Radiation that penetrates only five centimeters into the brain of an adult will reach much deeper into the brains of children because their skulls are thinner and their brains contain more absorptive fluid(易吸收的液体). No studies have yet been completed on cell phone radiation and children, she says.
Henry Lai, a research professor in the bioengineering department at the University of Washington, began laboratory radiation studies in 1980 and found that rats exposed to radiation had damaged DNA in their brains.
Ms. Davis recommends using wired headsets or the phone’s speaker. Children should text rather than call, she said, and pregnant women should keep phones away from the abdomen(腹部).
小题1:According to Ms Davis, brain cancer increase ____.
A.among children | B.among old people |
C.in the twenties | D.among pregnant women |
A.Because they haven’t grown up. |
B.Because they are too young to protect themselves. |
C.Because they use cell phones more often than adults. |
D.Because their skulls are thinner and their brains are easily hurt. |
A.Pregnant women should keep cell phones away. |
B.People should use cell phones in the correct way. |
C.If you are a child, you’d better text than make phone calls. |
D.When you use a cell phone, use a wired headset or the phone’s speaker. |
A.Be careful when using cell phones. |
B.Don’t hold your cell phone against your ear. |
C.Rats exposed to radiation have damaged DNA in their brains. |
D.Low-energy radiation could damage cells that could lead to cancer. |
