i have finished my paper in one third time that you did
2个回答

我来吧:

1.i have finished my paper in one third the time that you used.

我已经完成了我的论文,用的时间是你所用的三分之一.

定语从句的先行词要有定冠词,did意思不通,改为used就明朗了.

2.how can you hope for a high salary if you don't make your efforts

hope for 希望得到,effort此处要复数形式.

如果你不努力,又怎能够获得高薪水呢?

3.i managed to buy a flat at three hundred pounds,which was a bargain

原句有中式思维,必须改为非限制性定语从句,which指前面成功买房这件事.

我以300英镑的价位购得一套公寓,这是划算的交易.

4.do some meaningful things;don't waste time to idling about

waste time +doing浪费时间做某事 idle about 游手好闲 无所事事

做些有意义的事情吧,别游手好闲的浪费时间.
