7、一般说来,all和all of 都可以放在有限定词(如冠词、物主代词等)修饰的名词之前.
但是,如果名词前面没有限定词,则不能用all of.ballet dancers 前没有冠词the,所以只能用all不能用all of.
6.这句是时间状语从句," its___ into atoms of carbon and hydrogen"是主句.如果选A,breaking up 作伴随状语,主句就是its hydrocarbon molecules,只剩主语部分没有谓语,句子成分不完全.
10.如果选A,direct ...to..使某事物转向或对准某一方向,句意不通.本来direct 就是及物动词"指示"的意思,所以连接词前面不需要加介词,直接用which/that directs 就可以了 答案选D
