规则
Separate three or more items in a list with commas. Do not put a comma before the first item or after the last item.
三个或以上的项目用逗号隔开。第一项之前和最后一项之后不加逗号。
✔ 正确： The kit includes a map, a compass and a torch.
✘ 错误： The kit includes, a map, a compass and a torch.
→ 改正： Remove the comma after "includes".
技巧: Commas go between items, never between the verb and the list.
