sudden的用法总结

作者:opple 时间:2023-11-06 阅读:()

  【拓展】

  in addition表示“此外(还……)”,相当于副词besides。▲In addition / Besides, the building has to draw upon windows, allowing people to use the sun for light during the day. 此外,该建筑还得依赖窗子,以便让人们在白天用太阳光来照明。

  in addition常置于句首,用逗号与整个句子隔开,也可用于句末。▲I paid 100 yuan in addition. 此外,我又付了100元。

  (注意:(1)in addition to中的to是介词,其后接名词、代词、动名词;in addition本身是副词短语,常作插入语。

  (2)当主语后面跟有in addition to,as well as,along with,with,together with,rather than,but,except,besides,including等引导的词组时,其谓语动词的单复数由主语的单复数决定。▲Tom as well as two of his friends was invited to the party. 汤姆以及他的两个朋友一起被邀请参加晚会了。)

  10. used to be为动词不定式省略结构,此处省略了be动词后的important,仅保留动词不定式符号to(如果to后是动词be或have“有”时,be和have不能省略),以避免与上文内容的重复。可以用动词不定式符号to来代替上文出现过的动词不定式结构的情况有:

  (1)在助动词或情态动词之后,如have to,ought to等。▲She must go, but you don’t have to. 她必须走,但你没有必要。

  (2)在want,decide,like,love,hope,wish,mean,refuse,try等动词之后。▲You may go with them if you hope to. 如果你希望的话,你可以和他们一起去。

  (3)在ask,tell,order,advise,persuade,warn,wish,permit,allow,forbid等动词之后的宾语补足语中。▲Don’t do anything unless your father tells you to. 除非你父亲叫你去做,不然不要做任何事情。

  (4)在对话的答语中的happy,glad,eager,anxious,willing,ready,pleased,afraid等形容词后。

  ▲—Will you present the awards in person? 你亲自颁奖好吗?

  —I’m willing to. 我很愿意。

  11. therefore ADV:因此,所以▲I’ve never been to China and therefore I don’t know much about it. 我从没去过中国,所以对它知道的不多。▲He was very tired, and therefore he didn’t give the report at the meeting. 他非常疲倦,所以在会上他没有作报告。
