本题考查的是need的用法。“need”作为实义动词时,通常用法是:人+ need +to d0,故B正确。【知识拓展】need还可以用作情态动词,用法如下:1.need表示“需要”或“必须”,通常用于否定句和疑问句。例:0)You needn’t do it again.你不需要再做了。②Need he do this homework first?他需要先做这些作业吗?2.在否定句中,可以用need的否定形式+不定式完成时。例:①We need’t have worded.其实我们不必慌张。②You needn’t have mentioned it.你本来不必提起这件事。3.needn’t后的不定式有时也能用进行时或被动语态。例:He needn’t be standing in the rain.他不必要站在雨中。
