A.pay的修饰对象有歧义,可以作为后置定语修饰law,law paying...显然是不对的。pay也可以作为状语修饰动词boycotted 或者protest, 但逻辑意思也显然不对。 B.for which 引导状语从句,但此从句没有主语。 C.previously要用adj. 插入语把逻辑流打乱。因为插入语完全可以后置而不产生歧义。 D.Most of Portugal’s 250,000 university students boycotted classes in a one-day strike to protest a law that requires them to contribute $330 a year toward the cost of higher education, instead of the $7 per year required previously. E.toward/to the cost...不能用for. |
