1、CancerCancer is a group of many related diseases that begin in cells, the body\'s basic building blocks. The body is made up of many types of cells. Normally cells grow and divide to produce more cells as they are needed to keep the body healthy. Sometimes, this orderly process goes wrong. New cells form when the body does not need them, and old cells do not die when they should. The extra cells form a mass of tissue called a growth or tumor. Benign (良性的) tumors are not cancer. They can often be removed and, in most cases, they do not come back. Malignant (恶性的) tumors are cancer. Cells in malignant tumors are abnormal and divide without control or order.Scientists have learned that cancer is caused by changes in genes that normally control the growth and death of cells. Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer. Many gene changes that lead to cancer are the result of tobacco use, diet, exposure to ultraviolet radiation from the sun, or exposure to carcinogens (致癌物) in the workplace or in the environment. Some gene alterations are inherited.Cancer treatment can include surgery, radiation therapy, chemotherapy （化疗), hormone therapy, and biological therapy. The doctor may use one method or a combination of methods, depending on the type and location of the cancer, whether the disease has spread, the patient\'s age and general health, and other factors. Because treatment for cancer can also damage healthy cells and tissues, it often causes side effects. Patients and doctors generally discuss the treatment options, weighing the likely benefits of killing cancer cells and the risks of possible side effects.Having cancer does not always mean having pain. Whether a patient has pain may depend on the type of cancer, the extent of the disease, and the patient\'s tolerance for pain. Most pain occurs when the cancer grows and presses against bones, organs, or nerves. Pain may also be a side effect of treatment. However, pain can generally be relieved or reduced with prescription medicines or over-the-counter drugs recommended by the doctor.Gene alterations may be caused by____.【单选题】

A.prescription medicines

B.control or order

C.tolerance for pain

D.various factors

E.normal genes

F.different genes side effects

正确答案:D

答案解析:根据题干线索词Gene alterations定位原文至第二段第二句“Certain lifestyle and environmental factors can change some normal genes into genes that allow the growth of cancer”，题干中的alterations与句中的change虽然词性不同，但意思相同。题干将该句由主动态变为被动态，由此推断，句中画线部分即为题干所需添加成分。而D选项various factors是对该部分的同义改写，故为正确答案。

3、Breast Cancer Deaths Record LowThe number of women dying from breast cancer has fallen to a record low by dropping under 12,000 a year for the first time since records began.The Cancer Research UK data showed that 11,990 women died in the UK in 2007.The previous lowest figure had been recorded in 1971-the year records began after which it rose steadily year by year until the late 1980s.Professor Peter Johnson, Cancer Research UK\'s chief clinician said, "It\'s incredibly encouraging to see fewer women dying from breast cancer now than at any time in the last 40 years, despite breast cancer being diagnosed more often. "Research has played a crucial role in this progress leading to improved treatments and better management for women with the disease."The introduction of the NHS (国民保健制度) breast screening program has also contributed as women are more likely to survive the earlier cancer is diagnosed. "Breast cancer is now the most common cancer in the UK with 45,500 women every year diagnosed with the disease, a 50% rise in 25 years.The number of deaths peaked in 1989, when 15,625 women died. It then fell by between 200 and 400 deaths each year until 2004.There was a slight rise in 2005 and then two years of falls.Dr Sarah Cant, policy manager at Breakthrough Breast Cancer, said, "It is great news that fewer women are dying from breast cancer and highlights the impact of improved treatments, breast screening and awareness of the disease. " ."However, this is still too many women and incidence of the disease is increasing year by year."The rising rate of breast cancer diagnosis has been put down to a variety of factors including obesity（肥胖） and alcohol consumption.Breast cancer is more common in the UK than in many other countries.【单选题】

B.Wrong

4、Gun Rights in the US Immediately after the shooting at Virginia Tech University, Americans gathered to mourn the dead. The president and the state governor both hurried there to share the grief. But the majority of Americans still cling to their right to own weapons. Strictly speaking, the US is not the only country where gun violence has destroyed lives, families and communities in everyday circumstance. But the US is one of the ____ countries that seems unwilling and politically incapable of doing anything serious to stop it. In countries like Britain and Canada. The government adopted stricter gun control soon after serious gun violence incidents. US leaders, however, are held hostage by the gun lobby and the electoral system. The powerful National Rifle Association, the major supporter of gun rights in the US, is too strong for any party to take on. Most Republicans oppose gun controls anyway. Over the years, the Democrats have found that they can either campaign for gun control or win power, not both; they prefer power. According to the US Bureau of Justice Statistics, firearm incidents accounted for nine percent of the 4.7 million violent crimes in 2005. So, although opinion polls show most Americans want stricter gun laws, many don\'t want to give up their arms they keep to protect themselves. Dave Hancock, a Virginia gun lover, is one example. In an interview he said. "If one professor in Virginia incident had been carrying a legal weapon they might have been able to stop all this. " In his opinion, the massacre is an argument for more people to carry, weapons, not fewer. But at the root of Americans\' clinging to the right to bear arms is not just a fear of crime, but a mistrust of government , commented UK\'s Guardian newspaper. One Virginia resident, who had a permit to carry; a concealed firearm, told the Guardian thin itwas every American\'s responsibility to have a gun. "Each person," he said, "should not rely solely on the government for protection. " 【单选题】

A.few

B.some

C.much

D.little

正确答案:A

答案解析:首先，画线部分需要填一个可以修饰可数名词countries的词，所以可以排除C，D开头的but表示语义的转折，所以应该填few。

5、Smoking Can Increase Depressive Symptoms in TeensWhile some teenagers may puff on cigarettes to "self-medicate" against the blues, scientists at the University of Toronto and the University of Montreal have found that smoking may actually increasedepressive symptoms in some teens."This observational study is one of the few to examine the perceived emotional benefits of smoking among teens," says lead researcher Michael Chaiton, a research associate at the Ontario Tobacco Research Unit of the University of Toronto." Although cigarettes may appear to have self-medicating effects or to improve mood, in the long term we found that teens who started to smoke reported higher depressive symptoms. "As part of the study, some 662 high school teenagers completed up to 20 questionnaires ____ their use of cigarettes to affect mood. Secondary schools were selected to provide a mix of French and English participants, urban and rural schools, and schools located in high, moderate and low socioeconomic neighborhoods. Participants were divided into three groups: never smokers; smokers who did not use cigarettes to self-medicate, improve mood or physical state; smokers who used cigarettes to self-medicate. Depressive symptoms were measured using a scale that asked how felt too fired to do things: had trouble going to sleep or staying asleep; felt unhappy, sad, or depressed; felt hopeless about the future; felt vexed, antsy or tense; and worried too much about things."Smokers who used cigarettes as mood improvers had higher risks of elevated depressive symptoms than teens who had never smoked," says co-researcher Jennifer O\'Loughlin, a professor at the University of Montreal Department of Social and Preventive Medicine. "Our study found that teen smokers who reported emotional benefits from smoking are at higher risk of developing depressive symptoms."The association between depression and smoking exists principally among teens that use cigarettes to feel better. "It\'s important to emphasize that depressive symptom scores were higher among teenagers who reported emotional benefits from smoking after they began to smoke," says Dr. Chaiton.【单选题】

A.beside

B.beyond

C.in

D.about

正确答案:D

答案解析:本题要填入的词是介词。分析下来their use of cigarettes to affect mood应该是questionnaire（问卷）所要了解的内容，所以about是正确的选择。
