北邮-大学英语2-第一阶段作业答案

B. onesC. theseD. those学生答案: D; 标准答案: D;2.3. 试题分值：50.04. 得分：[5, 5, 5, 5, 5, 5, 5, 5, 5, 5]5. 提示：[1]C.考查主谓一致。

首先我们根据文章可以看出时态应该是一般现在时，所以B和D全部排除。

解决此题还要用到一个知识点：当主语是分数或百分数时,谓语动词的单复数由of 后面的名词决定。

再看这句话的主语是“75% of the earth’s surface”（地球表面的75%），这个主语中的“surface”是不可数名词，所以后面的谓语用单数形式“is”。

[2]A.考查名词辨析。

本句大意是“这么多水量中有97%都是海水，或称作咸水”。

解题关键是“水量”用哪个词来表达。

因为“水的数量”是不可数的，所以选择一个不可数名词才可以，即amount。

number意思是“数目”，但是它表示的“数目”是可数的。

volume的意思是“体积，容量”，意思不适合这里。

size的意思是“尺寸”，意思也不适合。

[3]A.考查连词辨析。

根据本句的意思（上题已经提到），我们选择or，其意思是“或者说”，用来引导同义词作补充说明。

[4]C.考查名词辨析。

source的意思是“来源”，resource的意思是“资源”，origin的意思是“起源”。

original一般作形容词用，意思是“起初的，原始的”，作名词用时意思是“原件，原稿”。

本句表示“别的水源”，当然应选择source来表达。

[5]D.考查定语从句。

“fresh water”后面的那个句子是一个定语从句。

又因为这个定语从句是非限定性的（判断的标志是fresh water后面的那个逗号），所以只能选择which来做定语从句的引导词。

[6]C.考查固定搭配。

“need for”的意思是“对……的需求”。

本句大意是“我们对水的需求在不断增加――几乎与日俱增”。

[7]A.考查形容词辨析。
