but的用法
1、broadcastbroadcast vt.;vi.广播;播放。过去式和过去分词均为broadcast。The BBC broadcasts every day.BBC每天都广播。
The news was broadcast on the radio.这个消息是收音机里播送的。
2、but
but ?prep. 除…之外。与except同义,除了的部分与其他部分不在一个范围内,不具有一致性。except适用场合较多,but 主要用于带有nothing/nobody/no one/all 等不定代词的句子。
No one except/but you was late.除你之外没有迟到。(你迟到了)
We all went to see a film yesterday evening except/but you.除你之外作天晚上我们都去看电影了。(你没去)
That window is open except in winter .除冬天外那窗户一直开着。(冬天不开)
另外,but后可接不不定式。如果句子前面有实义动词do及其变化形式时,不定式不带to; 否则不定式带to .
I did nothing yesterday evening but watch TV.昨天晚上除看电视外我什么也没干。
He had no choice but to leave.他只得离开。
注意:besides 也是介词,意为“除……之外(还有)”。除了的部分和其他部分在同一个范围内,具有一致性。We all went to see a film yesterday evening besides you.除你之外昨天晚上我们也都去看电影了。(你和我们都去了)
Who is going there with Tom besides you? 除你之外还有谁和汤姆一起去? 3、but for
该短语介词意为“要不是……”,后接名词(=without + n.),but for…短语相当于一个虚拟条件句,因此,句中谓语动词用虚拟语气。如:
The boy would have drowned but for your help.
如果接的是句子,but for要换用成but that…如:
He would have helped us but that he was short of money at the time.(= if it had not been the fact that he was…)
