Coffee is one of the world's most widely-enjoyed drinks. Now, a new research suggests that if you drink enough coffee, it might help you avoid certain kinds of cancer.
Dr. Mia Hashibe of the University of Utah School of Medicine was interested in the connection between coffee drinking and certain cancers of the head and neck. Researchers have looked into this before, but without reaching any firm conclusions. She said, "So this finding from our new study was quite a surprise. We didn't really have any expectation of which direction it could go into."
To sort out the confusion, Hashibe and her assistants used statistical (统计学 ) techniques to, in effect, make one big study out of the earlier smaller studies. She explained, "Thanks to the earlier studies, we have a lot more power than earlier studies that looked at this. And we included 4,000 cancer patients who have cancer of the mouth and throat. And then 9,000 controls, people who do not have cancer. '
Those studies--in Europe and the United States--found that people who drank a lot of coffee were less likely to develop cancers of the mouth and throat. "We saw a protective effect for drinking more than 4 cups of coffee per day," Hashibe said. "This was the 40 percent decrease in risk. We did not see the same effect for drinking three cups or less per day."
Mia Hashibe said there was a weak connection between cancer risk and drinking coffee without caffeine. And she and her assistants found no proof that drinking tea provided the same protection as drinking Coffee. Their research is published in the journal Cancer Epidemiology, Biomarkers & Prevention.
Hashibe says it is not clear how coffee might protect drinkers from certain cancers. "There are a few chemicals that are known to be antioxidants （抗氧化物）in coffee. So we are thinking perhaps they are playing some sort of protective role against several cancers."This passage is probably taken from __

Give it five minutes
I used to be a hothead. Whenever anyone said anything, I’d think of a way to disagree. I’d push back hard if something didn’t fit my world-view.
It’s like I had to be first with an opinion — as if being first meant something. But what it really meant was that I wasn’t thinking hard enough about the problem. The faster you react, the less you think. Not always, but often.
This came to a head back in 2007. I was speaking at the Business Innovation Factory conference in Providence, RI. So was Richard Saul Wurman. After my talk Richard came up to introduce himself and compliment my talk. That was very generous of him. He certainly didn’t have to do that.
And what did I do? I pushed back at him about the talk he gave. While he was making his points on stage, I was taking an inventory of the things I didn’t agree with. And when presented with an opportunity to speak with him, I quickly pushed back at some of his ideas. I must have seemed like such an asshole.
His response changed my life. It was a simple thing. He said “Man, give it five minutes.” I asked him what he meant by that? He said, it’s fine to disagree, it’s fine to push back, it’s great to have strong opinions and beliefs, but give my ideas some time to set in before you’re sure you want to argue against them. “Five minutes” represented “think”, not react. He was totally right. I came into the discussion looking to prove something, not learn something.
This was a big moment for me.
Richard has spent his career thinking about these problems. He’s given it 30 years. And I gave it just a few minutes. Now, certainly he can be wrong and I could be right, but it’s better to think deeply about something first before being so certain you’re right.
There’s also a difference between asking questions and pushing back. Pushing back means you already think you know. Asking questions means you want to know. Ask more questions.
Learning to think first rather than react quick is a life-long pursuit. It’s tough. I still get hot sometimes when I shouldn’t. But I’m really enjoying all the benefits of getting better.
If you aren’t sure why this is important, think about this quote from Jonathan Ive regarding Steve Jobs’ reverence(respect) for ideas:
And just as Steve loved ideas, and loved making stuff, he treated the process of creativity with a rare and a wonderful reverence. You see, I think he better than anyone understood that while ideas ultimately can be so powerful, they begin as fragile, barely formed thoughts, so easily missed, so easily compromised, so easily just squished.
That’s deep. Ideas are fragile. They often start powerless. They’re barely there, so easy to ignore or skip or miss.
There are two things in this world that take no skill: 1. Spending other people’s money and 2. Dismissing an idea.
Dismissing an idea is so easy because it doesn’t involve any work. You can scoff at it. You can ignore it. You can puff some smoke at it. That’s easy. The hard thing to do is protect it, think about it, let it marinate, explore it, riff on it, and try it. The right idea could start out life as the wrong idea.
So next time you hear something, or someone, talk about an idea, pitch an idea, or suggest an idea, give it five minutes. Think about it a little bit before pushing back, before saying it’s too hard or it’s too much work.
Those things may be true, but there may be another truth in there too: It may be worth it.Which of the following best describes the word hothead from the first paragraph?

| A．He kept notes for things that he did not agree with. |
| B．He pushed Richard and beat him. |
| C．He was preparing for his own speech. |
| D．He was getting ready to compliment him. |
Which of the following is the reason for quoting Jonathan Ive?
| A．The author thinks Steve Job is the best when it comes to creativity. |
| B．The author is inspired by Steve Job's attitude towards new ideas. |
| C．The author respects Steve Job because he is creative and he likes ideas. |
| D．The author thinks Steve Job has ideas that are strong and powerful and are hard to miss. |
What is the core argument that the author put forward?
| A．Dismissing ideas is an effortless thing to do so you should always protect ideas carefully. |
| B．The right idea always starts from a wrong idea and you need to protect it from being dismissed. |
| C．One should be careful when it comes to judge a new idea. |
| D．Every idea, whether powerful or fragile deserves five minutes |
Large companies need a way to reach the savings of the public at large. The same problem, on a smaller scale, faces practically every company trying to develop new products and create new jobs. There can be little prospect of raising the sort of sum needed from friends and people we know, and while banks may agree to provide short-term finance, they are generally unwilling to provide money on a permanent basis for long- term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business in exchange for a share in future profits. This they do by issuing stocks and shares in the business through the Stock Exchange. By doing so, they can put the savings of individuals both at home and overseas into circulation.
When the saver needs his money back, he does not have to go to the company with which he originally placed it. Instead, he sells his shares through a stockbroker to some other savers who are seeking to invest their money.
Many of the services needed both by industry and by each of us are provided by the government or by local authorities. Hospitals, roads, electricity, telephones, equipment and new development, if they are to serve us properly, require more money than it is raised through taxes alone. The government, local authorities, and nationalized industries therefore frequently need to borrow money to finance major capital spending, and then too, come to the Stock Exchange.
There is hardly a man or a woman in this country whose job or whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another, new money must come from the savings of the country. The Stock Exchange exists to provide a channel through which these savings can reach those who need finance.How does a company get the public to invest their savings for it according to the passage?
| A．By paying them very high interests for borrowing their savings. |
| B．By providing a share to them in the future profits. |
| C．By offering favorable terms to attract them to buy its products. |
| D．By selling its stocks and shares to them through the Stock Exchange. |
According to the passage, many services wanting to serve people properly haveto_______.
| A．get as much finance as possible through taxes |
| B．get the support from the government or local authorities |
| C．be able to provide what people really need |
| D．get persistent financial support |
According to the passage, what factor has a great effect on the workers’ job and living standard?
| A．Their employers’ policy for offering good welfare to them. |
| B．Their employers’ strategy for the company’s development. |
| C．Their employers’ capacity of raising money to finance new development. |
| D．Their employers’ ability to make the company obtain a great profit. |
Proper arrangement of classroom space is important to encouraging interaction. Most of us have noticed how important physical setting is to efficiency and comfort in our work. College classroom space should be designed to encourage the activity of critical thinking.
We are in the 21st century now, but step into almost any college classroom and you step back in time at least a hundred years. Desks are normally in straight rows, so students can clearly see the teacher but not all their classmates. The assumption behind such an arrangement is obvious: Everything of importance comes from the teacher.
With a little imagination and effort, unless desks are fixed to the floor, the teacher can correct this situation and create space that encourages interchange among students. In small or standard-size classes, chairs, desks, and tables can be arranged in a variety of ways: circles, U-shapes or semicircles. The primary goal should be for everyone to be able to see everyone else.
Arrangement of the classroom should also make it easy to divide students into small groups for discussion or problem-solving exercises. Small classes with movable desks and tables present no problem. Even in large lecture halls, it is possible for students to turn around and form groups of four or six. Breaking a class into small groups provides more opportunities for students to interact with each other, think out loud, and see how other students’ thinking processes operate---all these are essential elements in developing new modes of critical thinking.
In courses that regularly use a small group format, students might be asked to stay in the same small groups throughout the course. A colleague of mine, John, allows students to move around during the first two weeks, until they find a group they are comfortable with. John then asks them to stay in the same seat, with the same group, from that time on. This not only creates a comfortable setting for interaction but helps him learn students’ names and faces.The final purpose of arranging desks in circles or U-shapes is __________.
| A．for teachers to divide students into small groups |
| B．to make it possible for students to interact with each other |
| C．for teachers to find out how students think |
| D．to give students more opportunities to practice speaking |
The expression “step back in time at least a hundred years” is intended to convey that________.
| A．college classrooms often reminded people of their past |
| B．critical thinking was encouraged even one century ago |
| C．desk arrangement in a classroom was quite different from that a hundred years ago |
| D．today’s arrangement of college classroom space has little difference from past’s |
The way of arranging desks in classrooms in straight rows indicates that ________.
| A．students can be easily prevented from cheating during tests |
| B．it is convenient for teachers to monitor students |
| C．teachers play a significant role in a classroom |
| D．it is good for students to concentrate on listening to teachers |
Why do men die earlier than women? The latest research makes it known that the reason could be that men’s hearts go into rapid decline when they reach middle age.
The largest study of the effects of aging on the heart has found that women’s longevity may be linked to the fact that their hearts do not lose their pumping power with age.
“We have found that the power of the male heart falls by 20--25 percent between 18 and 70 years of age,” said the head of the study, David Goldspink of Liverpool John Moores University in the UK.
“Within the heart there are millions of cells that enable it to beat. Between the age of 20 and 70, one-third of those cells die and are not replaced in men,” said Goldspink. “This is part of the aging process.”
What surprises scientists is that the female heart sees very little loss of these cells. A healthy 70-year-old woman’s heart could perform almost as well as a 20-year-old one’s.
“This gender difference might just explain why women live longer than men,” said Goldspink.
They studied more than 250 healthy men and women between the ages of 18 and 80, focusing on healthy persons to remove the confusing influence of disease.
The team has yet to find why ageing takes a greater loss on the male heart, said Goldspink.
The good news is that men can improve the health of their heart with regular exercise. Goldspink stressed that women also need regular exercise to prevent their leg muscles becoming smaller and weaker as they age.The underlined word “longevity” in the second paragraph probably refers to ______.
| A．health | B．long life | C．aging | D．effect |
The text mainly talks about ______.
| A．men’s heart cells | B．women’s aging process |
| C．the gender difference | D．hearts and long life |
According to the text, the UK scientists have known that ______________.
| A．women have more cells than men when they are born |
| B．women can replace the cells that enable the heart to beat |
| C．the female heart loses few of the cells with age |
| D．women never lose their pumping power with age |
If you want to live longer, you should ___________.
| A．enable your heart to beat much faster |
| B．find out the reason for aging |
| C．exercise regularly to keep your heart healthy |
| D．prevent your cells from being lost |
We can know from the passage that __________.
| A．the reason why aging takes a greater loss on the male heart has been found out |
| B．scientists are on the way to finding out why the male heart loses more of the cells |
| C．the team has done something to prevent the male from suffering the greater loss |
| D．women over 70 could lose more heart cells than those at the age of 20 |
A Chinese couple tried to name their baby “@”, saying the character best represents their love for the child, according to an official trying to standardize the national language. The unusual name stands out especially in Mandarin, which has no alphabet (字母表) and instead uses tens of thousands of multistroke (多笔画的) characters to represent words. “The whole world uses it to write emails, and translated into Chinese it means ‘love him’,” the father explained, according to the deputy chief of the State Language Commission Li Yuming.
While the @ symbol is familiar to Chinese email users, they often use the English word “at” to sound it out. With a drawnout “t”, this sounds something like “ai ta”, or “love him”, to Mandarin speakers. Li says the name is an extreme example of people’s increasingly adventurous approach to Mandarin, as commercialization and the Internet break down conventions (习俗).
Another couple tried to give their child a name that in English sounds like “King Osrina”.
Li did not say if officials accepted the “@” name. But earlier this year the government announced a ban on names using Arabic numerals (阿拉伯数字) and foreign languages. Sixty million Chinese face the problem that their names use ancient characters so uncommon that computers cannot recognize them and even fluent speakers are left scratching their heads, said Li, according to a report on the government website. One of them is the former Premier Zhu Rongji, whose name has a rare “rong” character that gives newspaper editors headaches.Why did the Chinese couple try to name their baby “@”？
| A．Because they wanted their baby to have a special name. |
| B．Because they wanted their baby to have an international name. |
| C．Because the @ symbol is familiar to email users all over the world. |
| D．Because the @ symbol sounds something like “ai ta”, which means “love him” in Chinese. |
It can be inferred that ___________.
| A．Li Yuming is in favor of the baby’s name |
| B．many Chinese people use Arabic numerals in their names |
| C．a majority of the Chinese people are having longer names |
| D．there is little possibility for the “@” name to be officially accepted |
The underlined part in the passage probably means___________.
| A．even native speakers find it hard to accept these strange names |
| B．even native speakers can’t find these characters in their computers |
| C．even those who are expert at Chinese can’t recognize these characters |
| D．even those who are expert at Chinese find it hard to accept these names |
The former Premier Zhu Rongji is mentioned in the passage because ________.
| A．people often mispronounce his name |
| B．there is an uncommon character in his name |
| C．he often made newspaper editors annoyed during his term in office |
| D．he once stressed the importance of standardizing Chinese characters |
The passage is mainly about ___________.
| A．how Chinese parents name their babies |
| B．the importance of standardizing Chinese characters |
| C．a ban on names using Arabic numerals and foreign languages |
| D．the problems caused by uncommon characters used in Chinese names |
