B对 A. all the other planets, each of which contributing according to its which引导的是定语从句,没有谓语 B. all the other planets, each contributing according to its 如果要A对,那应该怎么改呢??
2. 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, previously paying $7 per year.B对 A. year toward the cost of higher education, for which was previously paid $7 per year pay的主语是谁不明确 B. year toward the cost of higher education, instead of the $7 per year required previously which不是指代education么,那education was paid for $7怎么会没有主语啊……?
