【用法详解】more than的用法主要有:
(1) 在“more than +数字”结构中,more than意为“超过,多于”,相当于over;反义短语为less than。如:
Do not write more than 200 words. 写的东西不要超过200字。
注意 “more than one +可数名词单数”意为“不止一个……”,其含义表复数概念,但形式是单数,即当此结构做主语时,其后的谓语动词用单数形式,类似用法还有many a(“许多……”)。如:
More than one meaning is included in some legal terms. 有些法律术语有不止一个含义。
(2) 在“more than +n.”结构中,more than意为“不止,不仅仅是”。如:
He’s more than a coach; he's a friend. 他不只是教练,更是朋友。
(3) 在“more than +adj./adv./v.”结构中,more than意为“很,非常”,相当于very (much), extremely。如:
He will be more than happy (=extremely happy) to come with us. 他巴不得和我们一起来。
She was more than a little shaken (=extremely shaken) by the experience. 这次经历对她产生了极大的震动。
I’m sure conditions over there will more than satisfy your requirements. 我确信,那边的条件会大大满足你的要求。
(4) “more than +句子(句中常含有can或could)”结构意为“非……所能……,是……难以……的”。如:
The heat there was more than he could bear. 那里的高温令他难以忍受。
【归纳拓展】与than相关的其他短语:
more A than B 与其B,倒不如A
less than 少于,不足
rather than 而不是
no more than 至多,不超过
no less than 多达
other than 除……之外(就没有了) -but, except
如:I have no ambitions other than to have a happy life and be free. 我没有雄心大志,只求自由自在地过幸福生活。
