易混辨析
instead/instead of/in place of/take the place of
instead 是副词，单独使用，用于句首或句末作状语，意为“而是，相反”。
instead of 是复合介词，后接名词、代词、或动名词，意为“代替、而不……”。
in place of 为介词短语，也是“代替、而不”的意思，表示“以甲代乙”，而instead of则是“用甲不用乙”，除“代替”外，还有对乙否定的意思，有时意为“不”。
take the place of (replace)作谓语，用在名词、代词前。
单项填空

d. instead of; than that one
②we will go there on footby bus. what about you? (2010·11·福建福州月考)
a. instead b. instead of c. without d. but
答案及解析：①：选a。to replace为不定式作目的状语。as it is意为“现在的样子”。
②：选b。 instead of意为“用一种形式代替另一种形式”。c项有一定干扰性，without意为“在没有……的情况下”，因此不合题意。
5. the number of “……的数量、数目”
作主语时谓语动词用单数；a number of意为“一些，很多”，相当于 many, 后接可数名词复数，当它作主语时，谓语动词用复数。
the number of competitors is limit. 参赛者的数量是有限的。
a number of problems have arisen. 已经出现了一些问题。
a large /great/good number of；a great/good many;a good few/quite a few+可数名词复数，意为“大量的”；
a great/good deal; a great/ large amount of; quite a little+ 不可数名词，意为“大量的”；
a lot of/lots of; a great /large quantity of; large quantities of/ plenty of +可数名词复数/不可数名词均可，意为“大量的”。但是a great/large quantity of ..., large quantities of ...作主语时谓语动词与quantity形式一致。
单项填空
