　　考試重點(diǎn)

　　that和those有時(shí)分別用來代表前面提到的不可數(shù)名詞和名詞復(fù)數(shù)，以避免重復(fù)。而可數(shù)名詞單數(shù)往往用the one 或that one 來代替。that 可以指上面提到的事情，this指下面要談的事情。

　　不定代詞中，both 放在實(shí)意動(dòng)詞前，系動(dòng)詞be 的后面。every只能跟名詞，each可以跟名詞也可以不跟名詞。every在代詞部分要出現(xiàn)當(dāng)每隔……講。

　　few， a few， many 修飾或指代可數(shù)名詞，little， a little， much修飾或指代不可數(shù)名詞。few， little表示否定。

　　one the other，some others，the others

　　it用法重點(diǎn)就是強(qiáng)調(diào)句。it作為形式賓語時(shí)不接is.

　　代詞部分的難點(diǎn)之一是名詞型物主代詞與形容詞型物主代詞的區(qū)別。顧名思義，形容詞型物主代詞起的是形容詞的作用，在句子中只能作定語，名詞型物主代詞起的是名詞的作用，代替上文出現(xiàn)的名詞，在句子中一般作主語、賓語、表語等。

　　A. our      B. us        C. we          D. ours
