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. |

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. |

When you’re surfing the Internet on your laptop from your dorm or home, do you know your personal details are being gathered secretly? And would you be surprised to know the information may be sold cheaply to advertisers and marketers?
According to an investigation by The Wall Street Journal, all it takes is a tiny file in a computer-a single code consisting of a long series of numbers and letters- to record the computer user’s age, gender, location, favorite movies and hobbies.
The newspaper reports that Lotame Solutions Inc., a New York company, uses sophisticated(高科技) software called a "beacon" to capture what people are typing on a website.
Lotame packages that data into profiles（个人资料）about individuals, only without their names, and sells the profiles to companies seeking customers．Batches of such data may be sold for a few dollars.
The Wall Street Journal survey discovered that spying on Internet users is one of the fastest-growing businesses on the World Wide Web.
The "cookie"- a tiny text file put on your PC by websites or marketing firms which might be used to remember your preferences for one site, or to track you across many sites is already old news．There are new and more complex tools such as "beacons" which scan in real time what people are doing on a webpage．These beacons instantly assess the Internet user’s location, income, shopping interests and even medical conditions.
Millions of Internet users around the world also face unprecedented（空前的）threats．Private, sensitive, personal and business information is being gathered and sold without their knowledge.
Companies insist the information they gather is anonymous and the data is used harmlessly. But the technology has grown so powerful that even some of the biggest websites in the US don’t know that they were installing intrusive files on visitors’ computers．These include MSN.com and Yahoo.com.
Next time you visit a webpage and find an ad banner advertising something you’ve been planning to buy, don’t be amazed that your computer can read your mind.The purpose of the passage is to .
| A．introduce a tiny file in a computer-a single code |
| B．show how your individual information was let out when you surf the Internet |
| C．show how to protect your privacy |
| D．introduce a sophisticated software called a "beacon" |
．All of the following statements are Wrong except .
| A．Lotame sells the profiles about individuals to companies seeking customers with their age, gender, location, hobbies and names |
| B．spying on Internet users is the fastest-growing businesses on the World Wide Web |
| C．some of the biggest websites in the US know they were installing intrusive files on visitors’ computers |
| D．a tiny file in a computer-a single code consisting of a long series of numbers and letters can record users’ information |
It can be inferred that .
| A．because the data is used harmlessly．Internet users around the world will not face threats |
| B．when a person surf the Internet, his personal details may be let out without his knowledge |
| C．your computer can really read your mind |
| D．MSN.com and Yahoo.com．use software to capture what people are typing on a website |
According to the passage, “beacon” .
| A．is a tiny text file put on your PC by websites |
| B．is a soft ware that can package that data into profiles about individuals |
| C．can assess the Internet user’s location, income, shopping interests and even medical conditions |
| D．is not more complex than the "cookie" |
What’s the writer’s attitude to this problem?
| A．Neutral | B．Worried | C．Optimistic | D．Indifferent |
It is pretty much a one-way street. While it may be common for university researchers to try their luck in the commercial world, there is very little traffic in the opposite direction. Pay has always been the biggest deterrent, as people with families often feel they cannot afford the drop in salary when moving to a university job. For some industrial scientists, however, the attractions of academia (学术界) outweigh any financial considerations.
Helen Lee took a 70% cut in salary when she moved from a senior post in Abbott Laboratories to a medical department at the University of Cambridge. Her main reason for returning to academia mid-career was to take advantage of the greater freedom to choose research questions. Some areas of inquiry have few prospects of a commercial return, and Lee’s is one of them.
The impact of a salary cut is probably less severe for a scientist in the early stages of a career. Guy Grant, now a research associate at the Unilever Centre for Molecular Informatics at the University of Cambridge, spent two years working for a pharmaceutical (制药的) company before returning to university as a post-doctoral researcher. He took a 30% salary cut but felt it worthwhile for the greater intellectual opportunities.
Higher up the ladder, where a pay cut is usually more significant, the demand for scientists with a wealth of experience in industry is forcing universities to make the transition (转换) to academia more attractive, according to Lee. Industrial scientists tend to receive training that academics do not, such as how to build a multidisciplinary team, manage budgets and negotiate contracts. They are also well placed to bring something extra to the teaching side of an academic role that will help students get a job when they graduate, says Lee, perhaps experience in manufacturing practice or product development. “Only a small number of undergraduates will continue in an academic career. So someone leaving university who already has the skills needed to work in an industrial lab has far more potential in the job market than someone who has spent all their time on a narrow research project.”By “a one-way street” (Line 1, Para. 1), the author means ________.
| A．university researchers know little about the commercial world |
| B．there is little exchange between industry and academia |
| C．few industrial scientists would quit to work in a university |
| D．few university professors are willing to do industrial research |
What was Helen Lee’s major consideration when she changed her job in the middle of her career?
| A．Flexible work hours. | B．Her research interests. |
| C．Her preference for the lifestyle on campus. | D．Prospects of academic accomplishments. |
Guy Grant chose to work as a researcher at Cambridge in order to ________.
| A．do financially more rewarding work | B．raise his status in the academic world |
| C．enrich his experience in medical research | D．exploit better intellectual opportunities |
What contribution can industrial scientists make when they come to teach in a university?
| A．Increase its graduates’ competitiveness in the job market. |
| B．Develop its students’ potential in research. |
| C．Help it to obtain financial support from industry. |
| D．Gear its research towards practical applications. |
The crisis at the damaged Fukushima Dai-Ichi Nuclear Power Station in northern Japan has raised worries about radiation risks. We spoke Tuesday with Jonathan Links, an expert in radiation health sciences. He is a professor at the Johns Hopkins Bloomberg School of Public Health in Maryland.
Professor Links says workers within the nuclear plant are the only people at risk of extremely high doses of radiation.
JONATHAN LINKS: "Of course, we don't know what doses they've received, but the only persons at risk of acute radiation effects are the workers."
For other people, he says, there may be a long-term worry. People can get cancer from low doses of ionizing radiation, the kind released in a nuclear accident.
Professor Links says scientists can use computers to quickly model where radioactive material has blown and settled. Then they measure how large an area is contaminated. He says if the situation is serious enough, officials could take steps like telling people not to eat locally grown food or drink the water.
JONATHAN LINKS: "But that would only be the case if there was a significant release and, because of wind direction, the radioactive material was blown over the area, and then settled out of the air into and onto water, plants, fruits and vegetables."
The reactors at Fukushima are on the Pacific coast. But Professor Links says people should not worry about any radioactive material leaking into the ocean.
JONATHAN LINKS: "Even in a worst-case scenario accident, the sea provides a very high degree of dilution. So the concentration of radioactivity in the seawater would still be quite low."
Japan is the only country to have had atomic bombs dropped on it. That memory fromWorld War Two would create a stronger "psychological sensitivity" to radiation exposure, Professors Links says.
Next month is the twenty-fifth anniversary of the explosion and fire that destroyed a reactor at Chernobyl in Ukraine. The nineteen eighty-six event was the world's worst accident in the nuclear power industry.
A new United Nations report says more than six thousand cases of thyroid cancer have been found. These are in people who were children in affected areas of Belarus, Russia and Ukraine. The report says that by two thousand five the cancers had resulted in fifteen deaths.
The cancers were largely caused by drinking contaminated milk. The milk came from cows that ate grass where radioactive material had fallen.

Life comes in a package. This package includes happiness and sorrow, failure and success, hope and despair. Life is a learning process. Experiences in life teach us new lessons and make us a better person. With each passing day we learn to handle various situations．
Love
Love plays a pivotal role on our life．Love makes you feel wanted．Without love a person could go Hayward(不归路) and also become cruel and ferocious．In the early stage of our life, our parents are the ones who show us with unconditional love and care, they teach us about what is right and wrong, good and bad．But we always tend to take this for granted．It is only after marriage and having kids that a person understands and becomes sensitive to others feelings．Kids make a person responsible and mature and help us to understand life better．

Happiness and Sorrow
Materialistic happiness is short-lived, but happiness achieved by bringing a smile on others face gives a certain level of fulfillment．Peace of mind is the main link to happiness. No mind is happy without peace. We realize the true worth of happiness when we are in sorrow．Sorrow is basically due to death of a loved one, failure and despair. But these things are temporary and pass away.
Failure and Success
Failure is the path to success. It helps us to touch the sky, teaches us to survive and shows us a specific way. Success brings in money, fame, pride and self-respect. Here it becomes very important to keep our head on our shoulder. The only way to show our gratitude to God for bestowing success on us is by being humble, modest, courteous and respectful to the less fortunate ones.
Hope and Despair
Hope is what keeps life going. Parents always hope their children will do well．Hope makes us dream. Hope builds in patience. Life teaches us not to despair even in the darkest hour, because after every night there is a day. Nothing remains the same we have only one choice keep moving on in life and be hopeful.
Life teaches us not to regret over yesterday, for it has passed and is beyond our control. Tomorrow is unknown, for it could either be bright or dull. So the only alternative is work hard today, so that we will enjoy a better tomorrow.In the passage, the author compares life to ．

You are enjoying the beautiful scenery in a quiet place, but suddenly the peace and quiet is interrupted（打断）by the noisy sound of a cellphone(手机)! Cellphones are everywhere, and some people don’t know what the limits of cellphone use are.
For me, it’s just a matter of education, good manners, and common sense. If I go to a beautiful place, it is because I want to enjoy nature. I can do it, but without bothering (打扰) other people.
Nowadays, that’s the biggest problem. People disturb other people, first with the ringing of their cellphones and then with their conversations because they usually speak very loudly. Not everybody in a public place should have to listen to private conversations (私人谈话). Even more annoying, you hear just one part of the conversation.
People need to learn how to use cellphones correctly. If there is an emergency (紧急情况)，cellphones are acceptable, but remember that just a few years ago few people had cellphones and the whole society survived!
But again, not everybody wants to listen to other people’s private conversations. It’s like smoking. People don’t want to be bothered by smokers. Our society has to learn to respect other people.
Sometimes when you are talking to someone, that person interrupts the conversation because of a cellphone call, without saying “I’m sorry.” That is bad manners. They don’t know how to respect other people. It’s just common sense! But our society is sometimes so “common senseless!” So, we have to write some rules to prohibit（禁止）cellphone use in some places.What could be the best title for the passage?
| A．Cellphone Manners Are a Must | B．How to Use Cellphones |
| C．Don’t Disturb Others | D．The Popularity (流行) of Cellphones |
According to the author, what is the biggest problem nowadays?
| A．People are disturbed by those who use cellphones. |

| A．smoking also does harm to other people’s health |
| B．people don’t want to listen to others talk |
| C．people don’t want to be bothered by cellphone talkers |
| D．some people don’t want others to smoke |
Which of the following is NOT true according to the passage?
| A．If we interrupt the conversation with a cellphone call, we should say sorry. |
| B．Some of the cellphone users don’t have good manners. |
