(2015·常州第三次质量预测)In 2013, a report from The New England Journal of Medicine showed that increased body weight is related to the death rate for all cancers. This is based on a study involving about 900, 000 people, spanning many years. The study, started in 1992 by the American Cancer Society, included men and women from all 50 states. The youngest participants were 30 years old, and the average age was 57. By December 2008, 24% of the participants had died, just a quarter of them from cancers. In
B．is remained D．has been remained
analyzing the results, researchers attempted to take account of such potential factors as smoking, drinking alcohol, taking aspirin and a wide variety of other factors that might otherwise affect the results.

The results are clear: the more you weigh, the greater your risk of dying of cancer will be (up to 52% higher for men and 62% for women). In men as well as women, the only cancers that did not have a strong connection with weight were lung cancer and brain cancer. For women, the strongest correlation with weight was uterine cancer (子宫癌), which is 6.5 times higher for women with a BMI (Body Mass Index) of 40 or more. For men, it was liver cancer, which is 4.5 times higher in most obese (肥胖的) men.

Smokers tend to be more successful in keeping weight off than non-smokers, slightly reducing the risk. But many of them don’t have good lungs. Thus, in another way, they also face risks.
As for why extra weight leads to excess cancer death rate, there’s no clear agreement. But the decrease in vitamin D in obese people seems a likely factor. Vitamin D is known to have a role in preventing cancer. Also，there is a simple fact that obesity makes the management of cancer more difficult. Although for now there is no simple answer to why obesity increases a person’s cancer risk, all we know for certain is that the risk is real.
1．The passage is mainly concerned with the relationship between________. A．diet and cancer C．sex and cancer
B．body weight and cancer D．smoking and cancer
2．The author develops the passage mainly through________. A．time order
C．analysis and comparison
B．space order D．figures and examples
3．The underlined word “spanning” in the first paragraph probably means“________”． A．lasting C．happening
B．including D．changing
4．According to the passage, what can we learn about the study?
A．There is a clear explanation concerning why obesity leads to more cancers. B．Generally speaking, women face fewer risks of dying of cancer than men. C．Women with a BMI of 40 dying of uterine cancer are more than other women. D．Smokers are still likely to face risks of dying of cancer though keeping weight off.

(2015·扬州中学模拟)Everyone has those nights — you lie in your bed for hours, tossing and turning，totally unable to fall asleep.You wish you could just turn your brain off as if it were a light. That would make things much easier, wouldn’t it?
Now it looks like you are one step closer to this wild dream of yours — scientists from Oxford University, UK have just discovered the “switch” that tells the brain to go to sleep, reported Forbes.
To understand the study, you first need to know that there are two mechanisms (机能) that regulate sleep. There’s one that we’re already familiar with — our body clock, which works in a 24-hour cycle based on the light changes throughout the day.
The other one is what scientists call the sleep “homeostat (动态平衡系统)”. This mechanism has nothing to do with daylight. Instead, it keeps track of the brain’s waking hours and urges it to rest if it has been awake for a long time. “It is similar to the thermostat (自动调温器) in your home. A thermostat measures temperature and switches on the heating if it’s too cold，”Professor Gero Miesenb?ck, who led the study, told The Telegraph.
Our bodies use both of the mechanisms to regulate sleep. “The body clock says it’s the right time, and the sleep thermostat has built up pressure during a long waking day，” explained Miesenb?ck.
There is no way that scientists can track the body clock. But with the sleep homeostat, there might be something they can do.
The researchers found that the sleep homeostat works by activating a specific group of nerve cells, or neurons, in the brain. They tested their theory on fruit flies by removing the neurons from the insects’ brains. And as expected, they found that the flies without the homeostat neurons did not keep a regular sleep pattern anymore.
Now that scientists have pinpointed (定位) the exact place in the brain — or, the “switch” — that regulates sleep, they can begin investigating (研究) how to activate these cells at any given time so that people can be sent to sleep instantly.
More importantly, figuring out how sleep mechanisms work may also help us to one day unravel one of the oldest mysteries of all: why do we need to sleep in the first place? 5．What is the article mainly about? A．A new way to treat sleep disorders. B．The discovery of the sleep “homeostat”． C．Advice on what to do when you fail to fall asleep. D．A comparison of the two mechanisms that regulate sleep. 6．How does the author explain the function of the sleep homeostat? A．Through examples. B．With comparisons.
C．Through cause and effect analysis. D．By presenting research findings.
