高中英语单选题
1.----To get a slim figure,Fanny has tried many ways,but in vain.----So now she is reduced _______ anything for supper.
B.to not eating C.not to eating
2.Word power section should be taken seriously because of the benefits ______ can have on the vocabulary of the students.
A.this B.it C that D.one
第二题请逐一分析其它选项为什么不可以?,说的简单一点,可以的话举个例句

选B；这里be reduced to中的to是介词,介词后要跟名词或动名词,动名词的否定形式是not doing,所以要选B,not eating；
选B；
（1）因为这是一句benefits后面省略了that/which的定语从句,即Word power section should be taken seriously because of the benefits 【that/which it】 can have on the vocabulary of the students.
（2）定语从句中的先行词which指代的是 the benefits,在从句中作宾语,从句的主语是it,即Word power section.如果不是从句的话,这句话应该是：Word power section can have benefits on the vocabulary of the students.意即,Word power这一部分/单元对于（提高）学生的词汇量大有益处.
（3）Word power section should be taken seriously because of the benefits 【that/which it】 can have on the vocabulary of the students.意思是：我们必须重视（认真对待）Word power这一部分,因为这一部分对于（提高）学生的词汇量大有益处.

再问：可是如果是定从，老师讲过只有做宾语的时候which that才可省略，这里明显是作主语啊，为什么可以省呢？
再答：没错啊，这个定语从句的主语是it，而先行词that/which it指代的是the benefits，在从句中作宾语。请看我的回答中的2/（2）
