Lucy likes Chinese为什么改为否定句为什么加doesn't?
因为英语实意动词的否定要靠助动词帮助实意动词【否定】,这个助动词就是do(第三人称用does),在助动词后面再加上not,就构成了否定,你说是吗?简单点号码?如：1.Lucy/He/She likes Chinese Lucy/He/She doesn't like Chinese.2.My classmates/We/I/You/They run fast. My classmates/We/I/You/They don'trun fast.为什么不用isn't?如果是系动词be，否定就直接在系动词后面加not。如：1.Lucy/He/She is Chinese Lucy/He/She isn'tChinese.2.My classmates/We/I/You/They are Chinese. My classmates/We/I/You/They aren't Chinese.祝你学习进步！如我的答案对你有帮助，请采纳，谢谢！
