共用题干Promising Results From Cancer StudyA new experimental vaccine（疫苗）has shown promising results in the fight against lung cancer. In a small Texas-based study,a vaccine developed by scientists at Baylor University Medical Centre in Dallas, USA,cured lung cancer in some patients and slowed the progress of the disease in others.Researchers have reported encouraging findings from this small study.Forty-three patients suffering fromlung cancer were involved in these trials.Ten of these patients were in the early stages and thirty-three in the advanced stages of the disease.They were injected with the vaccine every two weeks for three months,and were carefully monitored for three years.In three of the patients in the advanced stages of cancer,the disease disappeared and in the others,it did not spread for five to twenty-four months.However,no great difference was seen in the patients in the early stages of the illness.This new vaccine uses the patient's own immune system.It is made specifically for each patient and is injected into the arm or leg. It stimulates（刺激）the body' s immune system, which then recognizes that the cancer cells are harmful,and attacks and destroys them.The vaccine could be effective against other forms of cancer. It offers great hope for the treatment of cancer in general,although further studies are needed before such treatment can be widely used.Patients in the early stages of the disease recovered more quickly in the trial.A:RightB:WrongC:Not mentioned

共用题干Survey Found Many Women Misinformed About Cancer Sixty-three percent of American women think that if there's no family history of cancer,they're not likely to develop the disease,a new survey found. In fact,most people who develop cancer have no family history of cancer,according to the American College of Obstetricians and Gynecologists ( ACOG)（美国妇产科医师学会）,which sponsored the survey. "Too many women are dying from cancer,"Dr.Douglas W.Laube,ACOG's immediate past president, said during a Friday teleconference."An estimated 200,070 women will die in the U.S.this year,and over 600 , 078 women will be diagnosed with cancer.The results of this survey found a worrisome（令人担忧的） gap in women's knowledge about cancer." Based on the findings,ACOG is increasing its efforts to educate women about cancer and the need for regular screening tests. Although the survey found many misconceptions（错误观念）about cancer , 76 percent of women surveyed did say they feel knowledgeable about how they can reduce their risk of the disease. However,only 52 percent said they were doing enough to reduce that risk.And 10 percent said they hadn't done anything in the past years to lower their risk.17 percent said they wouldn't change their lifestyles, even if changes would lower their cancer risk. Many women said they were afraid to undergo screening out of fear of finding cancer.Twenty percent said they didn't want to know if they had cancer. In response to these findings,ACOG will launch on Oct.29 a new website-Protect & Detect:What Women Should Know about Cancer.The guide is designed to help women to take charge of their health and improve their understanding of their risk of cancer-and the lifestyle steps they can take to cut that risk.Some American women are just unwilling to change their lifestyles.A:Right B:Wrong C:Not mentioned

共用题干第三篇 Nuclear Power and Its DangerNqclear power's danger to health,safety,and even life itself can be summed up in one word:radiation.Nuclear radiation has a certain mystery about it,partly because it cannot be detected by human senses.It can't be seen or heard,or touched,or tasted,even though it may be all around us.There are other things like that.For example,radio waves are all around us but we can't detect them,sense them,without a radio receiver.Similarly,we can't sense radioactivity without a radiation detector. But unlike common radio waves, nuclear radiation is not harmless to human beings and other living things.At very high levels,radiation can kill an animal or human being outright by killing masses of cells in vital or-gans.But even the lowest level of radiation can do serious damage.There is no level of radiation that is completely safe.if the radiation does not hit anything important,the damage may not be significant. This is the case when only a few cells are hit,and if they are killed outright.Your body will replace the dead cells with healthy ones. But if the few cells are only damaged,and if they reproduce themselves,you may be in trouble.They reproduce them-selves in a deformed way. They can grow into cancer. Sometimes this does not show up for many years.This is another reason for some of the mystery about nuclear radiation.Serious damage can be done with-out the victim being aware at the time that damage has occurred.A person can be irradiated and feel fine, then die of cancer five,ten,or twenty years later as a result.Or a child can be born weak or liable to serious illness as result of radiation absorbed by its grandparents.Radiation can hurt us.We must know the truth.Which of the following can be best inferred from the passage?A:The importance of protection from radiation cannot be over-emphasized.B:The mystery about radiation remains unsolved.C:Cancer is mnainly caused by radiation.D:Radiation can hurt those who are not aware of its danger.
共用题干第二篇US Blacks Hard-hit by CancerDeath rates for cancer are falling for all Americans,but black Americans are still more likely to die ofcancer than whites,the American Cancer Society said Monday.In a special report on cancer and blacks, the organization said blacks are usually diagnosed with cancerlater than whites,and they are more likely to die of the disease.This could be because of unequal access to medical care,because blacks are more likely to have otherdiseases like diabetes as well,and perhaps because of differences in the biology of the cancer itself,the report added."In general,African Americans have］ess likelihood of surviving five years after diagnosis than whites forall cancer sites and all stages of diagnosis,"the report said."In describing cancer statistics for African Americans,this report recognizes that socioeconomic dispari-ties and unequal access to medical care may underlie many of the differences associated with race."The Cancer Society said blacks should be encouraged to get check-ups earlier,when cancer is moretreatable,and it said more research was needed to see if biological differences play a role.Cancer is more treatable if it is detected________.A:in an early stage B:together with other diseasesC:during check-ups D:in elderly people
