need, want, require后的非謂語(yǔ)動(dòng)詞

當(dāng)這三個(gè)動(dòng)詞表示“需要”時(shí)，其后接不定式和動(dòng)名詞均可，且意思基本相同，只是所用語(yǔ)態(tài)不同：接動(dòng)名詞時(shí)要用主動(dòng)式表示被動(dòng)含義，而接不定式時(shí)則要用被動(dòng)形式表示被動(dòng)含義。如：

1. The machine wants repairing.

= The machine wants to be repaired.

這機(jī)器需要修理。

2. These sentences need explaining.

=These sentences need to be explained.

這些句子需要加以解釋。

3. Lentils do not require soaking before cooking.

= Lentils do not require to be soaked before cooking.

小扁豆在烹飪前不必浸泡。
