大家能不能帮忙检查下面的两个句子
（1）As the amount of data obtained from mobile phones,which is functioned as the information to determine the traffic condition,is large.这句话好像显得头重脚轻,该如何改看起来舒服点呢,另外data好像是复数,amount 和后面的which is 的is用得正不正确呢?
（2）there is no prerequisite courses regarding Quantum Mechanics or materials are arranged before this course.这句话是不是出现了两个谓语了

Answer 1

1. the amount of data 是一个整体概念, 因此后面用 is
如果需要修改, 可改为：As large amounts of data obtained from mobile phones are functioned as the information to determine the traffic condition,.
2. there is no prerequisite courses regarding Quantum Mechanics or materials are arranged before this course. 其中可以在or materials are arranged 断开, 因此不是两个谓语.
上量子力学无需前期课程（预习课程）或者在上该课程前不必安排其他材料,
