Question

插入语可以这么用么?
1、Because the number of graduates has increased dramatically,according to
a survey carried by China Daily,covering these years.
2、Recently,the after-class activities,offered by schools,has increased
in great amount comparing with the number of past decades.

Answer 1

第一句的插入语没有问题,但是似乎语句不完整啊.
第二句建议去掉插入语两头的逗号,直接来,请看：
2、Recently,the after-class activities offered by schools have（activities是复数,用have,不用has） increased
in great amount comparing with the number of past decades.
