For one thing, though their sufferers are to be found in all age groups, cancers are particularly likely to attack persons in their middle and advanced years. Naturally, since people live longer these years, there are more cancer sufferers than before. Again, with better methods of diagnosis(诊断), doctors can more easily recognize cancerous growths that would formerly have passed unnoticed or that would have been wrongly diagnosed. It is also believed that certain habits and conditions of modern living, including heavy smoking and the pollution of the air, may leave people living in more cancercausing conditions than before.We all look forward to the day when a simple medical test can find cancer when it is still small. Researchers around the world are working on such_a_test. Most of their work deals with the examination of the blood.Researchers in Boston have found something in the blood of cancer patients that does not appear in healthy persons. The test showed which persons had cancer and which did not. It was correct more than 90 percent of the time.The researchers believe the test may be able to show cancer very clearly in its development. Cancers discovered early usually can be treated successfully.The test examines very small bits of fat in the blood called lipids (脂质). Cancers seem to change lipids although doctors do not know why. The test showed differences between the lipids of the persons with cancer and the lipids of those without cancer.The researchers say the new test could be a step to develop a simple way to check patients for cancer before the disease shows on an Xray.【语篇解读】本文为说明文，主要介绍了科学家在破解癌症问题方面所取得的一些研究成果。1Who will have cancer from the study of the researchers?AThe young.BThe middle aged and the older.CThe man.DThe woman.【解析】细节理解题。从第一段中的“cancers are particularly likely to attack persons in their middle and advanced years”可知，癌症特别容易在中老年人的身上发生。【答案】B2The underlined words “such a test” refer to _Athe test that shows which persons have cancer and which dontBthe test that may be able to show cancer very early in its developmentCa simple medical test that cannot find cancer when it is smallDa new test that could be a step to develop a difficult way【解析】词义猜测题。分析上下文可知，such a test与“a simple medical test can find cancer when it is still small”中的test指的是同一种方法，即“一种简单的能诊断早期癌症的方法”。【答案】B3Which of the following statements is TRUE according to the passage?ACancers have much to do with something in patients blood.BPeople living in better conditions are most likely to be attacked by cancer.CXraying is the best way to determine whether a person has cancer or not.DCancers have nothing to do with a persons habits and living conditions.【解析】事实判断题。第三段中提到了癌症病人血液中有的东西健康人的血液中却没有，并且百分之九十以上的情况是这样的。B项和D项与文章第一段中的最后一句话不符；C项与文章最后一段的意思不符。【答案】A4What would be the best title for the passage?AA simple way to cancerBCancers can be curedCHow to find cancerDEarly discovery of cancer【解析】标题归纳题。文章开头说有各种不同的理由说明癌症发病率似乎在不断上升，而后面的几段我们知道科学家们正在研究一种新的早期诊断癌症的方法。故D项为最佳标题。【答案】D.完形填空At age 86, Millie Garfield is one of the worlds oldest elderly bloggers (写博客的人)_1_ reading a newspaper article in 2003 and then asking her son for _2_ in getting online, Millie has been blogging ever since.We usually associate blogging with the _3_： our children, grandchildren, nieces or nephews.
