问题 共用题干1.Some of the most commonly used medicines for high blood pressure are drugs called ACE inhibitors（抑制剂）.Doctors have given these drugs to patients for twenty-five years.A government study in the United States found that the use almost doubled between 1 995 and 2000.
2.Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy（怀孕）.The medicine can injure the bahy.ACE inhibitors,though,have been considered safe when taken during the first three months.But a new study has found that women who take these drugs early in their pregnancy still increase the risk of hirth disorders（先天性疾病）.Thestudyshowsthat,comparedtoothers,theirbabieswerealmostthreetimesaslikely to be horn with major problems.These included problems with thefo朋ation of the brain and nervous system and holes in the heart.
3.The researchers say they found no increased risk in women who took other blood pressure medicines during the first three months.Researchers at Vanderbilt University in Tennessee and Boston University did the study. The New England Journal of Medicine published the results.The researchers studied the records of almost thirty thousand births between 1985 and 2000.Two hundred nine babies were born to women who took ACE inhibitors during the first three months of their pregnancies.Eighteen of the babies,or almost nine percent,had major disorders.
4.ACE inhibitors are often given to patients with diabetes（糖尿病）.But diabetes during pregnancy can result in birth defects（先天性缺陷）.So the study did not include any women known to be diabetic. ACE inhibitors suppress a protein called angiotensin-converting enzyme（血管紧张素转化酶）,or ACE. This enzyme produces a chemical in the body that makes blood passages narrow. The drugs increase the flow of blood,so pressure is reduced.
5.New drugs are tested on pregnant animals to see if they might cause birth defects in humans. But experts say these tests are not always dependable.The United States Food and Drug Administration helped pay for the study.The FDA says women who might become pregnant should talk with their doctor about other ways to treat high blood pressure.Paragraph 5___________A:Effects of ACE and ACE inhibitorsB:Wide use of ACE inhibitorsC:How to deal with high blood pressure in pregnant womenD:Damage to pregnant women's future babiesE:Suggestions on stopping the use of ACE inhibitorsF: Relative safety for women during the first three months of pregnancies
选项 Paragraph 5___________
A:Effects of ACE and ACE inhibitors
B:Wide use of ACE inhibitors
C:How to deal with high blood pressure in pregnant women
D:Damage to pregnant women's future babies
E:Suggestions on stopping the use of ACE inhibitors
F: Relative safety for women during the first three months of pregnancies
答案 C
解析 第二段说的是孕妇在孕期最后6个月服用ACE抑制剂会给未来婴儿带来伤害，婴儿患大病的可能性几乎是其他婴儿的3倍，包括大脑和神经系统发育缺陷及心脏漏洞等。
段首句及段尾部分的句子均表明：服用ACE的孕妇生下的孩子大部分没有什么严重的影响，因此F是答案。第三段说患高血压的孕妇在孕期前3个月服用其他降压药，她们的危险性并没有增加；即使服用ACE抑制剂，其婴儿也只有大约9％患大病。故妊振头三个月相对安全。
第四段说，ACE抑制剂可以抑制一种叫ACE的酶,ACE可以使血管变窄，而ACE抑制剂则可促进血液流动使血压下降。
第五段最后一句说，食品与药品管理局指出：患高血压的妇女在怀孕前应该向医生咨询治疗高血压的其他方法。因此C是正确答案。
答案相关句在文章的最后一句："The FDA says women who might become pregnant should talk with their doctor about other ways to treat high blood pressure."
答案相关句在第二段第一句："Doctors have known for years that women should not take ACE inhibitors during the last six months of pregnancy."
答案相关句在第三段："Two hundred nine babies were born to women who took ACE inhibitors during the first three months of their pregnancies.Eighteen of the babies,or almost nine percent,had major disorders."
答案相关句在第四段："ACE inhibitors suppress a protein called angiotensin-converting enzyme,or ACE.This enzyme produces a chemical in the body that makes blood passages narrow.
