Counterfeit medicines are a widespread problem in developing countries. Like other counterfeits, they look like real products. But counterfeit drugs may contain too much, too little or none of the active ingredients (原料) of the real thing.
People do not get the medicine they need. And in some cases the counterfeits cause death. Twenty children in Bangladesh died last year after being given acetaminophen (醋氨芬). The medications contained ingredients that looked, smelled and tasted like the real thing. The medicine was produced by a local drug company that used a dangerous substitute to save money.
The problem of counterfeit medicines is especially serious in Africa, Asia and Latin America. The WHO estimates that up to thirty percent of medicines on sale in many of those countries are counterfeits. The problem is less widespread among industrialized countries. The WHO says counterfeits make up less than one percent of the illegal drug market in countries like the United States, Canada, Japan, and New Zealand.
But the agency also says as much as fifty percent of the medicine sold on the Internet is counterfeit.
Much is being done to fight counterfeit drugs. Several companies are developing ways to make counterfeits easier to identify (鉴定). And there are existing methods, like a machine that can quickly identify chemicals in pills to confirm if the pills are real. Other ideas include things like special tracking (跟踪) codes for drug packages. People could send a text message with the code and get a message back, which proves that what they bought is listed in a database. Some drug makers and other companies put three-dimensional images called holograms (全息图) on their products as a security device. The underlined word “counterfeits” means _______.
| A．qualified products | B．sub-standard medicines |

Jerry Morris died on 28 October 2009. He was 99 years old. You have probably never heard of him. He was a professor of public health. More than 50 years ago he produced one of the most famous epidemiological (流行病学) papers of the 20th century.
His study showed that bus conductors were much less likely to die of heart disease than bus drivers. Why? Because the conductors spent their working day walking. It seems obvious now but in the middle of the last century doctors were puzzled by the rising numbers of people who got heart diseases. Jerry Morris found one of the main causes: a sedentary (久坐不动的) lifestyle. He started exercising for a few minutes each day and lived until his 100th year.
If you wish to protect your heart, you have to do more than wander in the garden. The exercise needs to be reasonable. Jogging is not for everyone and a round trip to the gym takes a couple of hours, plus the monthly membership fee is only good value if you visit regularly. The answer is simple: walk.
A half-hour purposeful walk five times a week will lower your risk of heart disease, diabetes and strokes. Older people sometimes feel they have left it too late. But it is never too late to start and there are no upper age limits. Start gently. Take your time: a 15-minute flat walk in the nearest park, four or five times a week. Within a month or so, you are already beginning to protect your heart. Build the walks up. When you can comfortably walk for half an hour in the park, go further: try following rivers and canals.
Regular walkers have their own natural gymnasium. There is no membership fee, just some of the finest scenery in the world. Great Britain is the walker’s gym. When you have followed the rivers and canals, and are enjoying walking for a couple of hours, head for the coast. Once again, build it up slowly. When you are comfortable with long coastal walks, you can think of our national parks.Jerry Morris is mentioned in the first paragraph mainly to __________.
| A．make his epidemiological message known to the public |
| B．praise his research into ways of improving public health |
| C．introduce the topic of doing exercise and keeping healthy |
| D．give an example of a person who lives a healthy and long life |
We can learn from the passage that __________.
| A．bus conductors are more likely to die of heart disease than bus drivers. |
| B．doctors in the 1950s knew why heart diseases kept happening to people. |
| C．walking is better than doing sports in a gym because it saves time and money. |
| D．British people love walking because they have free gymnasium with finest scenery. |
What suggestion does the writer give about walking?
| A．Parks are the best place for walking. |
| B．Starters should not push themselves too hard. |
| C．A two-quarter walk a day is suitable for starters. |
| D．People of old age might not be fit enough to start walking. |
What might be the best title for this passage?

| C．A Walk a Day Keeps the Doctors away |
| D．An Hour’s Walk in Nature is Worth Two in the Gym |
There is no question that fewer teenagers are on the roads in the US.
In 1978, 50% of 16-year-olds had got their first driving licence. In 2008, according to the US Transportation Department, it was just 30%. The number of those aged 19 and under with driving licences has also been declining since 1978, when 11, 989, 000 had licence. In 2010, it was 9, 932, 441, or 4.1% of American drivers.
In the UK, 683, 273 teenagers have driving licences- just 1.85% of total licence holders, according to Department of Transport figures from September 2010.
But the decline in the US may have more to do with tougher tests and the introduction of the new rule in many states, which force drivers aged under 16 to be with licensed drivers of 21 years and older when driving.
In recent years, the annual number of journeys being made by American drivers of all ages has declined clearly for the first time ever. Car use began falling in 2007, when average petrol prices almost doubled to $4.12 a gallon, and the economy became worse.
But there are signs that it is getting back to normal and American remains a country on wheels. It has a higher number of cars per head of population than any other country in the world.
“Cars will always be a popular means of transportation in America. You have to take into consideration some places don’t have access to public transportation. Cars are the only way some people can get around,” says Kristin Nevels. This makes driving necessary in some rural states, where about twice as many teenagers are on the road than in big cities. The underlined word “declining” in the second paragraph most probably means “__________”.
| A．rising | B．dropping | C．improving | D．holding |
In recent years cars are used less than before mainly because of __________.
| A．traffic jams | B．harder tests | C．expensive petrol | D．worst economy |
We can learn from the last paragraph that Kristin Nevels __________.
| A．doubts the popularity of the car use in the future. |
| B．thinks American people can not live without cars. |
| C．holds confident attitude to the cars’ future in America. |
| D．believes America should build up its public transportation. |
What can be inferred from the text?
| A．The UK has more teenager drivers than the US. |
| B．A 15-year-old boy cannot drive alone in the US. |
| C．The US has very developed bus transportation system. |
| D．Big cities have more teenager drivers than rural areas in the US. |

I arrived late one night on a business trip, so I decided to have dinner in the hotel I stayed in. As I was finishing my meal, an elderly couple came in. They were holding hands and had lovely smiles on their faces. They sat three tables from me. I was amazed at the love they showed for each other. It stuck me because it was shortly after ending a 20-year marriage and I still had pain in my heart.
My waiter was also their waiter. As I paid my bill, I asked what their bill was. He told me, and I gave him $40 to pay their bill. He asked if I knew them and I told him “No, I just wanted to repay them for the love that they were showing to each other,” and then I left.
The next day I entered the restaurant again. After I had been seated, the waiter who served me the night before told me that the strangest thing happened after I left the restaurant. When the elderly couple went to pay for their meal, they were told that it had been paid. The waiter just told them what I said. They were amazed. They looked around, asked for the bill of two young couples who were seated together, paid their bill and left.
I smiled and ordered my meal. About 45 minutes later, I finished my meal and was about to head out, but my waiter was nowhere to be found. I explained to the hostess that I needed to pay for my meal and hurry to the airport. She smiled and explained that I would not have to pay, because she felt she should pay for my bill because of the joy brought to the faces of the elderly couple and the amazement of the young couples.
When I told her that they didn’t have to do that, she said with a smile “Love creates Love.”From the first paragraph we know the writer must feel __________.

"Hey, don't read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. “Don’t read in poor light!” This is one of the common beliefs that are supposed to help us live a healthy life. Such beliefs are, however, without scientific basis(根据), according to a paper published recently in the British Medical Journal.
Do you believe in the following sayings?
Reading in poor light ruins your eyesight.
In poor light, you might blink (眨眼) more, suffer from drying and have trouble focusing. But most of eye experts believe it is unlikely to do any damage forever.
We must drink at least eight glasses of water a day.
In 1945, the Nutrition Council in US suggested that people need to drink 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total.
We only use 10 percent of our brains.
This idea appears as early as 1907. People have long argued about our power of self-improvement and our brains’ possible abilities. But X-rays show that no area of the brain is silent or inactive.
Shaving your legs causes hair to grow black faster and thicker.
