问题描述:
【选择】50.it ( )Mike and Mary who helped the old man seveal day ago.
( were / was / are / had been)
这题选什么,理由是.
答
were ,因为several days ago 是过去时的时间状语,所以排除are,并且也没有明确的词汇表示这句话是完成时态,故排除had been,这里边的Mike and Mary 是两个人,所以用复数形式,所以应填were
答
选was
it was .....who/ that 强调句式
本句是强调主语:Mike and Mary
翻译下,几天前,就是麦克和玛丽帮助那个老人的。
答
was这是一个强调句结构,它的构成 是:It is.+被强调部分+..that/who.+剩下部分It was.+被强调部分+..that/who.+剩下部分也就是说,在这个句子中,是IT作主语,无论什么时候,谓语动词只能用单数.不存在用WERE的情况了.又...
答
was。因为主语是it,又是过去时。
