答案与题解：

1.        D第二段说的是孕妇在孕期最后六个月服用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三倍，包括大脑和神经系统发育缺陷及心脏出现空洞等。

2.        F第三段说患高血压的孕妇在孕期头三个月服用其它降压药，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。故妊娠头三个月相对安全。

3.        A第四段说，ACE抑制剂可以抑制一种叫ACE的蛋白质，ACE可以使血管变窄，而ACE抑制剂则可增加血流使血压下降。

4.        C第五段说到，虽然目前正在妊娠动物上试验新药，但其结果也不一定可靠，因此患高血压的妊娠妇女还是要去咨询医生。

5.        D本题答案存在于文章的最后一句。talk with与consult with的意思相同，都是“咨询、商量”的意思。

6.        B第二段第一句说到，多年来医生已经知道，妇女在妊娠的后六个月不应该服用ACE抑制剂。

7.        F第三段后半部说到，研究人员研究了大约30，000个婴儿，其中209个婴儿的母亲在妊娠的头三个月服用过ACE抑制剂，但只有18个婴儿患有大病，大约占9%。

8.        A本题答案存在于第四段倒数第二句，该句说，这种酶(即ACE)可使血管变窄。
