　　(2) which，what同为名词性从句的连接代词时，都可在所连接的名词性从句中充当主语或宾语，其区别在意思上。what强调"内容"，而which强调从已知的、确定的范围中做出选择。This river, which flows through London, is called the Thames.

　　辨析：need, require与want: (1) 三者后接名词、代词或数词，意思为"要"或"需要"。三者后接被动的不定式或主动的动名词，意思为"需要"或"应该"。(2) need (需要) 和want (想要) 可以接主动的不定式作宾语，而require不可以。(3) require和want可以接复合宾语，而need不可以。(4) require可以接宾语从句，而且从句中的谓语动词必须用"(should+) 动词原形"；need和want不可以。(5) need可以作情态动词，而require和want不可以。例如：The work needs / requires / wants patience. 这工作需要耐心。The house needs / requires / wants to be cleaned / cleaning. 这房子需要清扫。He needs / wants to see you. 他要见你。I require / want you to be here this evening. 我请你今晚到这儿来。They require that I (should) appear. 他们要求我出场。You need not write down your translation. 你们不必写下译文。
