A: I think it is a good idea for students to ride their bicycles to school.
I have two reasons for this.
First of all, they can save many because it is not necessary for student to buy train tickets. ①
Second, ride bike is a lot of fun. ②
For example, it feels refreshing. ③
In conclusion, I think it is a good idea for students to ride their bicycles to school.
① many → money/ student → them/ train → train or bus
② ride bike → "riding a" bike 自転車に乗ること
※いきなり動詞は命令文かと思われてしまいますよ><
③ 普通に②とつなげた方が良いですね。
Riding a bike is a lot of fun, and it feels refreshing.
