There is a lot of time系动词为什么用is 后面有a lot of 不是用助动词are吗
time 不可数,尽管用a lot of 修饰,there be 句型是要看与系动词最近的单复数形式而定的.如there are 2 desks and one chair in the room.或是there is one chair and two desks in the room.所以此处用is.

Also, when there is a lot of activity going on, time passes quicker.不是应该a lot of activities going on.吗？ 题有错误。
