The team conducted a computer—based analysis to determine the 8

C.avoided

E.considerable

G.documented

I.excess

K.instancesM.revised

O.undertakeannually caused develop dramatically

答案及解析：

1.L.参考解析：该处需填人形容词，修饰后面的名词decrease.意思为：即便将日常食盐的摄入量进行适量的减少都可带来极大的健康益处，形容词considerable显然不符合句意，因此填入形容词modest.

2.G.参考解析：此处需要填人动词作句子的谓语，且用动词的一般过去式。依据句意，该处应该填入动词document的过去式，表示作者通过数据记录减少食盐摄入量后，心脏病、中风和心肌梗塞相对应减少的病例。

3.K.参考解析：此处需要填入名词，和前面的心脏病例(cases of heart disease)，本句的中风实例(instances of stroke)以及后面的心肌梗塞(heart attacks)担当同样的句子成分，因此，应该填入名词instanceso

4.D.参考解析：此处需要填入过去分词作后置定语，因为心肌梗塞(heart attacks)是因为高血压引起的，分词和它做修饰的名词短语

是被动关系，所以填人过去分词表被动，依据句意进一步推断，该处

填人caused.

5.F.参考解析：此处需要填入动词原形，和be likely to do构

成固定搭配，意思是：很有可能做某事。填入动词原形develop(发展，形成)，非洲裔的美国人比其他种族更易患上高血压，正好符合原文意思。

6.I.参考解析：此处需要填入名词，构成词组in excess of，意思是：超过;较…更多。故选I项excess，这句话的意思是：美国人食盐的摄入量远远超过健康需要的标准。

7.N.参考解析：此处需要填入副词修饰整个句子。在副词分类中

选中slightly(轻微地)最符合题意，强调即使是微量的减少食盐摄入量，也会让健康受益。

8.J.参考解析：此处需要填入名词。依据该句句意：研究团队进

行了一项电脑分析，来检测每天减少3克食盐摄入量对心脏病患病率

和死亡率的影响，因此填入名词impact，符合句意。

9.C.参考解析：此处需要填入过去分词，由that引导的定语从

句中缺少构成谓语的过去分词，组成过去将来时的被动语态would

be+v-ed，填入过去分词avoided，意思是：通过血压的落低，某些疾

病将是可以避免的。

10.B.参考解析：此处填人副词，annually(每年)作为统计数据

的时间单位，意思是：通过全国范围的控盐运动，美国每年节约的医

疗费用为100亿到240亿美元。据此，可以判断选择B.
