It seems like every day there's some new research about whether our favorite drinks are good for us.  One day,  science says a glass of red wine a day will help us live longer. The next day, maybe not.  It seems journalists are pretty interested in wine research and the same might be said for coffee.  Now there's been a lot of research into whether coffee's good for our health "the results have really been mixed"，admits Neal Freedman who led the coffee study and published his findings in a medical journal recently.   "There's been some evidence that coffee might increase the risk of certain diseases and there's also  been  maybe  more recent evidence that coffee  may protect against other diseases as well".

Freedman and his colleagues undertook the biggest study yet to look at the relationship between coffee and health.  They analyzed data collected from  more than  400，000 Americans ages 50 to 70 participating in the study.  "We found that the coffee drinkers had a modestly lower risk of death than the non-drinkers， he said.  Here's what he means by "modestly": those who drank at least two or three cups a day were about 10 percent or 15 percent less likely to die for any reason during the 13 years of the study when the researchers looked at specific causes of death, coffee drinking appeared to cut the  risk  of  dying from  heart  disease, lung  disease injuries,  accidents  and infections.

Now, Freedman stressed that the study doesn't prove coffee can make people live longer .A study like this can never prove a cause-and-effect relationship.  All it can really do is to point researchers in the right direction for further investigation. And even if it turns out that coffee is really good for you, scientists have no idea why.

Can you believe everything that you read? It seems as if every day, some new articles come out about a new discovery about this or that. For example, water is bad for you, or good for you. The answer depends on which scientific study has just come out. People cannot decide which food items are healthy, how pyramids were constructed, and why dinosaurs disappeared. When we look for answers we sometimes can believe persuasive researches and scientists. But how trustworthy are they really? Here are two examples of scientific hoaxes (骗局).

As far back as 1726, Johann Beringer was fooled by his fellow scientists into thinking he had made an amazing discovery. The fossils of spiders, lizards, and even birds with the name of God written on them in Hebrew were unlike anything that had been found before. He wrote several papers on them and was famous for those only to have it revealed that they were planted by jealous colleagues to ruin his reputation.

When an early human being was discovered in 1912, scientists at this time were wild with excitement over the meaning it had for the theory of evolution. There were hundreds of papers about this Piltdown man over the next fifty years until it was finally discovered to be a complex hoax. The skull (头骨) of a man had been mixed with the jawbone of an orangutan (猩猩) to make the ape (猿) man.

The next time you read the exciting new findings of a study of the best scientist, do not automatically assume that it is true. Even qualified people can get it wrong. While we certainly should not ignore scientific research, we do need to take it with a grain of salt. Just because it is accepted as the truth today does not mean it will still be trustworthy tomorrow.

1.What does Paragraph 1 want to say?

A. Researchers and scientists are not perfect.

B. Something that we read may not be true.

C. Researchers and scientists know everything.

D. People don’t know whether water is good or bad.

2.What is the reason why Johann Beringer was fooled?

A. His fellow scientists wanted to make fun of him.

B. His workmates are eager to become famous too.

C. These scientists made a mistake because of carelessness.

D. His colleagues envied him and did so to destroy his fame.

3.The excited scientists thought that this Piltdown man ______.

A. was in fact a complex hoax

B. was a great scientific invention

C. contributed to the theory of evolution

D. had the skull like that of an ape

4.What does the underlined phrase “with a grain of salt” in Paragraph 4 mean?

A. Happily.        B. Generally.        C. Doubtfully.        D. Completely.

5.What can we learn from the passage?

A. Hebrew is probably a kind of language.

B. Truths of science will never be out of time.

C. People believe scientists because they are persuasive.

D. We are advised to believe famous scientists.

While it may seem like everyone surfs the web these days, there is fine line between casually checking your social media pages and having a full blown Internet addiction. If you fear that you may lose interest in other aspects of your life because you prefer to be on the Internet, you may be on your way to an Internet addiction.1.

Admit you are at risk of an addiction.

More and more people in the world are becoming addicted to the Internet. You are not the only one with this problem; it is becoming more and more common and more and more well known.2..

Set aside limited time for computer use.

Make sure not to turn it on too many times a week. If you have a laptop, make sure to put it somewhere that you can remember but not somewhere that you see every day. Try keeping the lid closed when you are not using it; 3. If you have a desktop PC, try not to go near it or put something over it like a sheet.

Call people instead of sending instant messages or texts.

If you are free on weekends, call friends and ask them to go outside. This will distract you from the computer.4.

Use an alarm clock or timer.

Before using your computer, decide on a time limit such as 30 minutes. Set the clock or timer and make sure that you get off the computer when the time is up. Alternatively create a shutdown timer on your desktop. 5..

A. Make a small list of what you want to do within that time.

B. When the computer is not looking at you, you are less likely to use it.

C. This can be programmed to shutdown your computer after the set time

D. Luckily, there are ways to avoid living your life in front of the computer.

E. This will stop you from using the Internet so often or going on to another page.

F. If you have a problem on weekdays, phone your friends or ask for help in person.

G. Do not be embarrassed; find others with the same problem and help each other beat it.

Unless you’re very young or very old,it's likely you have some kind of relationship with email, whether you get hundreds of messages a day or a few dozen a week. A new study suggests that how we deal with these incoming messages could be affecting our stress levels and overall health.

A team from the Future Work Centre in the UK surveyed 2,000 people across various industries, sectors, and job roles, asking participants how they managed their email and how much associated stress they felt as a result. Overall, those who spent the most time organising and staying on top of messages felt the most email-related pressure too.

“While email can be a valuable communication tool, it’s clear that it’s a source of stress of frustration for many of us. The people who reported it being most useful to them also reported the highest levels of email pressure!” said one of the team, Richard MacKinnon.

Two of the habits linked to more email-related stress were checking for messages first thing in the morning and last thing at night. Half of those surveyed had push notifications (消 息推送）set up for new email, while 62 percent of respondents left their email app open all day and all night. Both were linked to higher levels of email pressure. The survey also found that managers suffered more than non-managers.

Stress is not just a problem when it comes to our mood—it’s been linked to a lot of disorders such as heart disease， weight gain， memory impairment (减弱），digestive problems,and depression.

The researchers suggest that the relationship between email-related stress and the negative impact on home life is not the same for everyone.

1.What’s the purpose of the study?

A. To find out how many people have an email account.

B. To know what sort of people use email most.

C. To find out how email management is related to stress.

D. To show what changes email has brought about to people.

2.What does Richard Mackinnon think of email?

A. It brings more strengths. B. It is not an essential tool.

C. It is a double-edged sword. D. It makes people puzzled.

3.Which of the following habits causes the most stress?

A. Checking email in the morning.

B. Checking email in the evening.

C. Keeping email app open at work.

D. Setting up push notifications for new email.

4.Where does the text most probably come from?

A. Science fiction. B. A science report.

C. fashion magazine. D. A book guide.

Like every dog, every disease now seems to have its day. World Tuberculosis (infections disease in which growths appear on the lungs) Day is on Saturday March 24th.

Tuberculosis was once terribly fashionable. Dying of “consumption” seems to have been a favorite activity of garret-dwelling 19th-century artists, has, however, been neglected of late. Researchers in the field never tire of pointing out that TB kills a lot of people. According to figures released earlier this week by the World Health Organization, 1.6 million people died of the disease in 2005, compared with about 3m for AIDS and 1m for malaria. But it receives only a fraction of the research budget devoted to AIDS. America’s National Institutes of Health, for example, spends 20 times as much on AIDS as on TB. Nevertheless, everyone seems to getting in on the TB-day act this year.

The Global Fund an international organization responsible fur fighting all three diseases but best known for its work on AIDS, has used the occasion to trumpet its tuberculosis projects. The fund claims that its anti-TB activities since it opened for business in 2002 have saved the lives of over 1m people. The World Health Organization has issued a report that contains some good news. Although the number of TB cases is still rising, the rate of illness seems to have stabilized; the caseload, in other words, is growing only because the population itself is going up.

Even drug companies are involved. In the run-up to the day itself, Eli Lilly announced a $ 50m boost to its MDRTB Global Partnership. MDR stands for multi-drug resistance, and it is one of the reasons why TB is back in the limelight. Careless treatment has caused drug-resistant strains to evolve all over the world. The course of drugs needed to clear the disease completely takes six mouths, anti persuading people to stay that course once their symptoms have gone is hard. Unfortunately, those infected with MDR have to be treated with less effective, more poisonous and more costly drugs. Naturally, these provoke still more. non-compliance and thus still more evolution.

The other reason TB is back is its relationship to AIDS. The (global Fund’s joint responsibility for the diseases is no coincidence. AIDS does not kill directly. Rather, HIV, the virus that causes it, weakens the body’s immune system and exposes the sufferer to secondary infections. Of these, TB is one of the most serious. It kills 200 000 AIDS patients a year. However, some anti-TB drugs interfere with the effect of some anti-HIV drugs. Conversely, in about 20% of cases where a patient has both diseases, anti-HIV drugs make the tuberculosis worse. The upshot is that 125 years after human beings worked out what caused TB, it is still a serious threat.

1.The first sentence “Like every dog, every disease now seems to have its day.” means _______.

A.every dog enjoys good luck or success sooner or later

B.human beings can deal with problems caused by disease

C.Tuberculosis becomes a serious infection disease

D.people attach importance to Tuberculosis recently

2.By referring to AIDS in Paragraph 2, the author intends to show _______.

A.the US government is reluctant to spend millions of dollars on Tuberculosis

B.the death rate of AIDS is higher than that of Tuberculosis

C.the officials didn’t pay much attention to the research of Tuberculosis in the past

D.compared with AIDS, Tuberculosis can be cured effectively

3.Which of the following is best defines the word “upshot” (Para 5)?

A.Outcome. B.Uphold.

C.Achievement. D.Project.

4.Which of the following proverbs is closest in meaning to the message the passage tries to convey?

A.Forgive and forget.

B.Forgotten, but not gone.

C.When the wound is healed, the pain is forgotten.

D.Every dog is brave at his own door.
