题目

1.At last,we found ourselves in a pleasant park with tress providing shade and () down to eat our picnic
a.sitting b.sat
我选a了 为啥不行?
2.()of the truth of the reports,he told his colleagues about it.
a.convincing.b.convinced
3.A man's first care should be () the reproaches of his own heart
a.avoid b.to avoid
should后不应接原型吗,为啥选b啊?
4.the building is () to be finished next week
a.demanded b.hoped.c.said
a为啥不对.那座楼被要求在下周竣工不这么说吗?

答案

1. sit是和found并列,与found时态要一致
2.Convinced of the truth of the reports,he told his colleagues about it.确信了这个报道的事实后,他把这告诉了他的同事.
这是个分词做状语的从句,原句是He was convinced of the truth of the reports.He told his colleagues about it.主语一致可省略一个,使省略句做状语,省略时主谓同时省略.
3.should后面不接原型那么怎么会有be呢,be不是原型么,be to do sth.动词不定式做表语,译为：一个人的急救应避免良心上的谴责
4.demand要引导虚拟语气的,而后面的形式不是虚拟语气,所以用hope比较合适
