“China now has 350 million smokers, accounting for one-third of the world total. Chinese smokers now become addicted to nicotine at the age of 19, five years earlier than the average starting age of 24 in 1997,” a report said a couple of years ago.
Of the 1.1 billion smokers all over the world. more than 800 million are in developing countries. And as the world's largest developing country, China also has the largest number of smokers.
Some frightening facts start to appear when we examine who China’s smokers are. Of the 350 million addicts, more than 100 million are under the age of 18, while more than 50 percent of male teachers and doctors are smokers.
Such a high rate of addicts among male teachers and doctors will certainly have a bad impact on the young generation.
Teachers are usually expected to be role models for students who tend to consider whatever they do is right and follow their example. It is very likely that the number of teenage smokers will increase in the near future unless measures are taken to forbid teachers from smoking in front of their students or designate schools as no-smoking zones.
What is truly puzzling is why so many doctors smoke. They are aware of the results of the habit, such as high blood pressure and lung cancer. Their example only helps justify the addiction of so many others.
If educated people set an example by stopping smoking at least in public places. it would be much easier to drive home the notion that it is uncivilized to smoke in public places.
In China, there should also be a national law to ban smoking in public places. These would make a massive contribution to cutting the number of people in China who are smoking themselves into early grave.Which of the following can serve as the best title for the passage?

They tell us when to get up or when we’re running late for work and whether we are in danger of missing our favourite TV programme. But while our daily routines rely on clocks that tell us the time, science is discovering that our well-being is influenced by a very different kind of timepiece. Circadian rhythms---the human body’s own internal clock---have a powerful influence on our health and behaviour. They are programmed from birth and control functions ranging from temperature and blood pressure to sleep patterns.
In recent years researchers have also discovered that this built-in mechanism can influence everything from the way we react to medicines to how well we learn music.
The latest example, from experts at Harvard University in the US, shows that the human body clock can even dictate whether or not we are likely to tell the truth. Researchers found it was easier for people to fib（撒小谎） in the afternoon because, as they were tired, the self control that would normally prevent them from lying started to break down. Tiredness made it harder to resist the temptation to tell lies---especially if it meant they got a financial reward at the end.
“The body clock has a great effect on us all,” says Professor Jim Horne from the Sleep Research Centre at Loughborough University. “Most people tend to feel good around late morning and then decline in the early afternoon. But the time most of us will feel our sharpest is between 6pm and 8pm. That’s because sleepiness tends to build up throughout the day. By early evening our body clock kicks in to wake us up. One reason may be to ensure we get home safely. When our ancestors were coming home after hunting all day their internal clocks kicked in to get them home in one piece.”
So what effects do circadian rhythms have and what’s the best time of day to take advantage of them?
The underlined word “They” in the first paragraph refers to .
| A．our clocks | B．scientists and experts |
| C．our daily routines | D．circadian rhythms |
As the new semester begins，millions of college students across the country are trying hard to remember how best to write a paper-or，more likely，how best to delay that paper．
Procrastination is the thief of time and a lot of students suffer from it．They can spend whole days in the library doing nothing but staring into space，eating snacks，surfing the Internet，watching videos and looking at their pretty peers sitting around them，who，most likely，are doing nothing either．
Paralyzed by their habit to procrastinate，they write micro blogs about their fears，asking their online friends if they sometimes have the same issue．But this does nothing to solve their problems．
According to a recent report by the BBC，95 percent of us procrastinate at some point and 20 percent of the world’s population are procrastinators，complicating their lives with their continual delaying of tasks．
Procrastinators like to find excuses to justify their behavior，but BBC columnist Rowan Pelling says they are all wrong．Many procrastinators tell themselves they are perfectionists who work best under pressure．Pelling says this is nonsense，as work done at the last minute is more likely to have mistakes than work done on time．
She says the behavior of procrastinators often makes them feel flustered and ashamed，inconveniences others，and annoys loved ones．
Fortunately，social seientists have made tireless efforts to understand this behavioral shortcoming and offer strategies to control it．Piers Steel，a Canadian social scientist and author of The Procrastination Equation，believes humankind is“designed”to procrastinate．Nevertheless，he suggests a couple of good ways to get through the task at hand．
The first one is obvious：Break the task down into small pieces and work your way through them methodically．
The second is clever：Give a trusted friend a sum of money and tell them that if you don’t complete the task you have undertaken by a specific time，they can keep it or donate it to a cause you hate.
What does the underlined word“Procrastination” in the second paragraph refer to?
| A．A bad habit of putting work or tasks off． |
| B．A thief who steals time and money in college. |
| C．A college student who learns nothing． |
| D．A study way of doing nothing in the library. |
For many years, I was convinced that my suffering was due to my size. I believed that when the weight disappeared, it would take old wounds, hurts and rejections with it.
Many weight-conscious people also mistakenly believe that changing our bodies will fix everything. Perhaps our mistake is believing that being thin equals being loved, being special, and being cherished. We fantasize (幻想) about what it will be like when we reach the long-awaited goal .We work very hard to realize this dream. Then, at last, we find ourselves there.
But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally fulfill its promise of everlasting happiness, self-worth, and, of course, love.
It took me a long time to realize that there was something more for me to learn about beauty. Beauty standards vary with culture. In Samoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it’s happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us strive hard to change our body, but in vain. We have to find a way to live comfortably inside our body and make friends with and cherish ourselves. When we change our attitudes towards ourselves, the whole world changes.
What does the word “everything” in paragraph 2 mean?
| A．The whole world | B．All the problems. |
| C．All the properties. | D．The absolute truth. |
The Cuban iguana is a species of lizard（蜥蜴） of the iguana family． It is the largest of the West Indian rock iguanas, one of the most endangered groups of lizards． This species with red eyes and a thick tail is one of the largest lizards in the Caribbean．
The Cuban iguana is primarily herbivorous; 95% of its diet consists of the leaves, flowers and fruits from as many as 30 plant species, including the seaside rock bush and various grasses． However, Cuban iguanas occasionally consume animal matter, and individuals have been observed eating the dead flesh of birds, fish and crabs, The researchers wrote that quite a few people on Isla Magueyes could have caused this incident．
The Cuban iguana is distributed throughout the rocky southern coastal areas of mainland Cuba and its surrounding islands with a wild population booming on Isla Magueyes, Puerto Rico． It is also found on the Cayman Islands of Little Cayman and Cayman Brac, where a separate subspecies occurs． Females guard their nest sites and often nest in sites half destroyed by Cuban crocodiles． To avoid the attack from them, the Cuban iguana often makes its home within or near prickly-pear cacti （仙人掌）．
In general the species is in decline, more quickly on the mainland than on the outlying islands． One of the reasons for their decline is habitat destruction caused by the over consuming of farm animals, housing development, and the building of tourist resorts on the beaches where the animals prefer to build their nests． Although the wild population is in decline, the numbers of iguanas have been sharply increased as a result of captive-breeding（圈养） and other conservation programs．
The underlined word "herbivorous" （Paragraph 2） probably means ．
| A．dangerous | B．gentle |
| C．plant-eating | D．flesh-eating |
If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven't you noticed that you have become smarter since you started to learn a language?
According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles.
The study also found the effect is greater, the younger people learn a second language.
A team led by Dr Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of "early bilinguals" who had learnt a second language before the age of five, as well as a number of later learners.
Scans showed that grey matter density (密度) in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference.
"Our findings suggest that the structure of the brain is changed by the experience of learning a second language," said the scientists.
It means that the change itself increases the ability to learn.
Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. "Having two languages gives you two windows on the world and makes the brain more flexible (灵活的),"he said. "You are actually going beyond language and have a better understanding of different ideas."
The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of two and 34. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better. "Studying a language means you get an entrance to another world," explained the scientists.
The underlined word “bilingual'’ probably means ______.
| A．a researcher on language learning |
| B．a person who is good at learning foreign languages |
| C．a person who can speak two languages |
| D．an active language learner |
