The flu is believed ________by viruses that like to reproduce in the cells inside the human nose and throat.
答案to be caused,除了 sb/sth be believed to be done这个结构可以作为理由
外请再分析一下为什么选这个。越想越晕啊。我觉得CAUSE的也可以啊
At the beginning of class,the noise of desk_______could be heard outside the classroom.
opened of and closed
to be opened and closed
being opened and closed
to open and close
答案being opened and closed,不明白,这道题的解析里说到了“OF后面接动名词做宾语,OF后用了动名词的复合结构”。不止是说OF后的动词变成V-ING这个意思吧?
另外看到总结,什么什么词后跟带TO的不定式作补语,什么什么用不定式做宾语,这两列里面的词不一样啊。
我分不清它给的补语宾语句子成分的区别
比如书上做补语的词的例子
You are not allowed to smoke here.(意思是ALLOW带TO的不定式作补语),我不明白怎么算是补语了,宾补?!!!!
书上做宾语的词的例子
She pretended not to see me when i passed by.(意思是P用不定式做宾语)
如果上面那个算补语这个为什么不算?不都是动词+TO 动词了么
being opened and closed 那个是算状语吗?为什么?
Answer:(1)"is believed"已经是句中谓语了,当然不能再用cause.且这是个被动句,宾语提前放到了句首句中不能再有宾语.这里"to be caused"是不定式短语作“宾补”成分
(2)the nosie of sth(...)的噪声这是一个名词所有格结构,但of 本身是介词 ,sth 只能由名词或动名词来充当只不过这里用了动名词的复合结构.用此结构的目的是为了表明动名词的逻辑主语是谁." desk being opened and closed"在此动名词的复合结构中动名词短语"being opened and closed"的逻辑主语是"desk"它与"open ,close" 之间是动宾关
