mean后面要加s吗例：Do you know that the red light ______(意思是)“Stop”? Do you like bananas?后面为什么要加s Do you like kites?kite后面为什么加s? what's your mean what's you mean what you mean what do you mean到底哪个正确啊 what do you think 后面如果是名词+动词,那么动词是否因为DO而原型呢 我可能表达不好,举个例子举个例子what do think the word ——（mean）,括号中要因为word而加S,变meanS还是因为DO要原型, Which seasons do you like best?中的season为什么后面要加S呢 Do you believe their diet mainly consists of .vegetables?为什么consist后面要加S? 人教版新目标4单元教材的一个英语问题,What do you think anxious means?为什么这里的mean要加s, what does it mean的mean要不要加S you'd better It's better 后面分别加什么?do or to do? what do you mean what do you mean? what do you mean what do you mean. Do you mean it? do you mean to What do you mean It's clear that I do not mean(hurt)you.
