Part I Reading Comprehension

Section A

Directions:There are three reading passages in this section. Each passage is followed by some questions or unfinished statements. For each of them there are four suggested answers

marked A, B, C and D. Choose the best answer to each question.

Questions 1 to 5 are based on the following passage:

Doctors say very few children survived cancer before the nineteen seventies. Improved treatments now offer hope of long-term survival for almost eighty percent of young cancer patients. Yet the chemotherapy drugs and radiation used to stop their cancers can lead to other problems later.

A newly reported study looked at more than ten thousand adults who survived childhood

cancers. They were treated between nineteen seventy and nineteen eighty-six. Their average age at the time of the study was twenty-six.

The study compared their medical histories with those of three thousand of their brothers and sisters. The researchers found that sixty-two percent of the cancer survivors had at least one long-term health problem. The same was true of only thirty-seven percent of the brothers and sisters. The cancer survivors were eight times as likely as their siblings to have severe or life-threatening conditions as adults. And many of the survivors had three or more conditions.

The cancer survivors were at higher risk of problems like heart disease and early bone loss. Chemotherapy can damage bone growth during an important period of development. And radiation for some cancers can increase the risk of other cancers later.

Survivors of bone cancers, cancers of the central nervous system and Hodgkin's disease were at highest risk for health problems as adults. The study also found that girls who survived cancer were more likely than boys to have problems later.

Doctors say newer cancer treatments are a little safer but not much. Still, the good news is that many of the conditions linked to cancer treatments can be found when they are still treatable.
