The production of grain has been increased by four times this year.今年粮食产量增加了4倍
这个句子用了现在完成时
下面这个句子:
The grain output is 8
percent higher this year than that of last year.今年比去年粮食产量增加8%
为什么不需要?
还有在书写的时候数字直接写 不用eight这样写吗?
应该完成时被动语态

时态问题:第一个句子的动词用的是increase,增长,是一个已经完成的动作,所以用完成时;第二个句子直接用系动词is,表示现在的状态,所以用现在时.俩都对,两种方式都可以用.
书写问题:对,欧美国家一般也用阿拉伯数字,所以直接写没问题,但特别正式或者需要准确说明的文件一般都用英文写数字,而不用阿拉伯数字.
再问: 但是第一句好像是一个完成时被动语态 has+been+动词过去分词 用完成时可以理解 但是被动语态这是为什么呢?
再答: 因为这个句子表示的不仅是increase还有increase的程度 - four times. 如果仅仅说,the production of grain has increased this year. 也是对的。但要表示增加了4倍,就得用被动式:The production of grain has been increased by four times this year. 如果用主动地话就是这样了:the production of grain this year is four times higher than that of last year.
