常见错误

❌ 错误:I covered the box by a cloth.
✓ 正确:I covered the box with a cloth.

错误使用了介词 by。cover 表示“用某物覆盖”时,应用 with 而不是 by,by 通常用于被动语态表示动作执行者。

❌ 错误:The book's cover is very interesting to read.
✓ 正确:The book's cover is very attractive to look at.

cover 作为名词指书的封面,是视觉对象,不能说“读封面”,应改为“看封面”或描述其外观。

近义词辨析

conceal

conceal 强调故意隐藏或保密,带有隐瞒的意味;cover 更中性,泛指遮盖或保护,不一定有隐藏意图。

He tried to conceal his emotions (故意隐藏情绪) vs. She covered the table with a cloth (简单地用布盖住桌子)。

include

include 指包含作为整体的一部分;cover 作为动词时,在商务或保险语境中表示范围或费用上的涵盖,可能更抽象。

The price includes breakfast (价格包含早餐) vs. The insurance covers accidents (保险涵盖意外事故)。
