有两个错误.
1、like 有两种用法,一个是like sth.还有是like to do sth.
所以这里你要么改成like going to the mall 要么改成like to go to the mall
2、shop作为名词额时候是商店的意思.这里你想要使用的意思应该是“购物”,而不是“商店”.shopping表示“购物”.所以应该是shopping
综合以上,有两种改法:
1、l like to go to the mall on the weekend because shopping is fun
2、l like going to the mall on the weekend because shop is fun
