【篇章导读】本文是议论文。

要不要参加课外活动对于许多学生来说是个必要权衡利弊的题目。

1.E　本空为本段的主题句,本段主要阐述了参加课外活动的学生们在学习方面体现更突出,即到场课外活动的利益。

2.F　本空是对前一句的举例说明,且下一句中的webecamefriends与F项中的Imetmybestfriend在语意上相干。

3.C　由本空前一句可知,本段开始阐述参加课外活动的弊端;而本空后面的内容是对本空的进一步表明阐明,阐述的是此中一个毛病,即让学生们更繁忙。

4.B　B项内容与下一句形成因果关系,本空后面的Thissituation指代B项内容。

5.G　本空前一句与G项内容形成迁移转变干系,即课外活动虽有利益,但学生们需要适当奇妙地摆设时间,以应对繁忙的生存。
