the number of ＋ n．(pl.)表示“……的数量”。作主语时，谓语动词用第三人称单数形式。表示数量的多少，用large和small, 不用many和few。如： (1)a large / great/good number of
a great many
a good few / quite a few ＋ n. (复数)
(作主语，谓语动词用复数形式) ① the number of ＋ n.(pl.) 表示“许多”的短语 (2) many a
more than one ＋ n. (单数)
(作主语，谓语动词用单数第三人称形式) ① the number of ＋ n.(pl.) 表示“许多”的短语
(3) a great/ good deal of
quite a little ＋ n. (不可数名词)
(作主语，谓语动词用单数第三人称形式) (作主语，谓语动词根据amount的单复数决定) (4) a large amount of
large amounts of ＋ n. (不可数名词) ① the number of ＋ n.(pl.) 表示“许多”的短语 (作主语，谓语动词根据quantity 的数决定) (5) a large quantity of
large quantities of ＋ n. (复数)或＋ n. (不可数名词) 辨析 the number of / a number of a number of＋可数名词，意为“许多的、大量的 ……”，其后的谓语动词用复数； the number of＋可数名词，意为“……的数目”，
其后的谓语动词用单数。 ① the number of ＋ n.(pl.) 活用
单项填空 (1) The number of foreign students attending Chinese universities ______ rising steadily since 2009.
A. is
B. are
C. has been
D. have been
解析 考查主谓一致和时态。主语是 the number of foreign students, 故谓语动词用单数，又因时间状语是since 2009，所以用完成时态。 ① the number of ＋ n.(pl.) C (2) With more forests being destroyed，huge quantities of good earth ______ each year.
A. is washing away
B. is being washed away
C. are washing away
D. are being washed away 解析
考查主谓一致。quantities of后既可接不可数名词，也可接可数名词，其谓语动词根据quantity的数确定，所以答案是D。 ① the number of ＋ n.(pl.) D (3) Good amounts of sleep every night______ also important for your health.
A. is
B. are
C. was
D. were 解析 考查主谓一致和时态。amounts of 后只接不可数名词，作主语时谓语动词和amount的数保持一致，由于其时间是every night，要用一般现在时，所以答案是B。 ① the number of ＋ n.(pl.) B ②at an end

②at an end
结束，终止(常作表语) by the end of in the end at the end of 你知道这道题的正确答案是什么吗？为什么？ They walked and walked until they came ______ the
end of the stream.
A. at
B. by
C. in
D. to ②at an end
结束，终止(常作表语) D ②at an end
结束，终止(常作表语) 解析 首先我们知道by the end of后不跟地点；in the end是一个独立使用的短语；虽然at the end of 后接地点，但它所表示的是“在……的尽头或末尾”，表示状态。而本题的语境所表示的是“来到了溪流的尽头”，所以答案是D。

当as if引导从句时，我们一定要根据语境判断 语义是否符合客观实际，符合客观实际就用陈述语 气，即：该用什么时态就用什么时态；不符合客观 实际就用虚拟语气，即： as if ＋ 主语 ＋ had done sth.
(从句谓语动词发生在过去) did / were
(从句谓语动词发生在现在) would do sth.
(从句谓语动词发生在将来) 巧记： had done did/ were would do
之前 谓语动词

好像我们队会赢。 ② 引导方式状语从句：
He treated her as if she were his daughter.

He acts as if (he were)a fool / mad.
他做事像个傻子 / 像疯了一样。
Tom raised his hands as if (he were going) to say
something.
汤姆举起手好像要说什么。 活用
根据汉语提示完成句子 (1) There are masses of dark clouds in the sky. It seems as if it __________(将要) rain.
(2) He talked as if he __________(知晓) everything in the world.
is going to had known 解析
(1)从“天空中乌云密布”，我们就可以判断出天要下雨的可能性相当大，所以我们用陈述语气，因是客观推测的将来，所以答案是is going to。 (2)从语境：他说起话来就好像他穷知世界一切似的。“穷知世界”这是不可能的，所以我们要使用虚拟语气。根据本句语境know的动作应发生在talk之前，所以用had known。 活用
