For years, doctors have given cancer
patients three main treatments: surgery, radiation and chemotherapy. Now
researchers are developing a fourth weapon: the patient’s own immune
system. New vaccines and drugs can stimulate the production of an army of cells
and antibodies that kill cancer cells. Drug-vaccine therapy may be lifesaver for Deerfield man. Few people survive advanced melanoma, but immune therapy is giving Deerfield resident Douglas Parker a fighting chance. The 46-year-old salesman noticed a mole on his chest three and a half years ago that was found to be cancerous. Doctors removed the mole but didn’t get all of the cancer. The cancer spread to other parts of his body, including his liver, where a tumor grew as large as a baseball. Parker took interferon and interleukin-2 to boost his immune system’s ability to fight the cancer. The A. replacing cancerous cells B. boosting the immune system C. killing cancer cells directly D. quickening the reproduction of cells [填空题]According to the article, doctors have observed that a typical patient feels depressed, impatient and angry.
[单项选择]Doctors have known for a long time that extremely loud noises can cause hearing damage or loss. The noise can be the sound of a jet airplane or machines in factories or loud music or other common sounds found at home and at work.
A person only needs to hear the noise for little more than one second to be affected. An American scientist has found that using aspirin can increase the temporary hearing loss or damage from loud noise. He did an experiment, using a number of male students at a university who all had normal hearing. He gave them different amounts of aspirin for different periods of time, then he tested their hearing ability. He found that students who were given four grams of aspirin a day for two days suffered much greater temporary hearing loss than those who did not use aspirin. The hearing loss was about twice as great. The scientist said millions of persons in the United States use much larger amounts of aspirin than were used in the study. He said these p A. often take jet airplanes on trips B. like listening to loud music C. are drowned in loud noises at home as well as at work D. take too much aspirin [单项选择]For years, doctors have given cancer patients three main treatments: surgery, radiation and chemotherapy.

In August, 1997, surgeons removed it, along with two thirds of his liver. Last January, doctors disc A. Within a decade, immune therapy will replace the other treatments. B. In the near future, immune therapy will prove to be a better treatment. C. For some time, immune therapy will not be tile only treatment for the desired effect. D. Within the next five to ten years, immune therapy will only be the main treatment for cancer. 我来回答: 提交
