...attached to a long stick which helped keep the rocket ...

优质解答

省略了to 其实是helped (to) keep

其他回答

help do sth 帮助做某事

这个其实是省略to的动词不定式，其实是 help to do sth

也就是说 这句话中 keep the rock doing是动词不定式充当宾语。

倒装句.

only引导时间状语从句when humanity began to get its food in a more productive way.

因为这部分状语前置,所以主谓要倒装.

还原过来就是

这不是个完整的句子,而是个名词性从句,你可以把它用作宾语,如：

He didn't know 【how the puma had managed to cover such great distances within a day】

他不知道【美洲狮一天之内怎么走了这么远距离的】

当然,你也可以把它用作主语,表语,或者同位语.

可以从句子结构上看看

Mike was at his wits' end 到这里这个句子可以说结束了,

那么后面的what to do 就是作为宾语补足语的存在的

问题4：分析句子结构!he would probably be highly indignant if told of what anyone familiar with modern psychology can recognize so plainly.分析这个句子的结构[英语科目]

主体句子结构：

【He 主句主语】【would probably be highly indignant谓语】【 if（he should be从句主语和谓语动词一部分被省略）told of what anyone familiar with modern psychology can recognize

so plainly 条件状语从句】.

状语从句结构（里面含有宾语从句）：

if(【he从句主语】【 should be) told of 谓语】 【what （anyone 宾语从句主语）（familiar with modern psychology形容词短语,定语） （can recognize宾语从句谓语）（so plainly状语）宾语从句】.
