to lack in 怎么用啊 和 be lacking in 什么区别
下面这句话用的什么句型?A person who holds a hand over his mouth when he is talking is signalling that he is lacking in confidence.
答
先翻译你那句话: 一个人说话时用手捂住嘴, 说明他缺乏自信. be lacking in 缺少,缺乏 , 没有, lacking 是形容词They are lacking in noth...那原句用的是 be lacking in 还是lack in是 be lacking in , 表示状态, 说明他是一个一贯缺乏自信的人。 如把be lacking in 当作是lack in的现在进行时，则强调动作，“正缺乏自信”，这显然不合逻辑。
