"Do"和"Does"都是英語中的助動詞。
一般來說,它們的使用和區(qū)別如下:
1. 主語為第一人稱單數(shù)(I)、第二人稱單數(shù)(you)和復數(shù)(we、they、you等),都用“do”。例如:- I do my homework every day.- You do a great job at work.- We do not have enough money to travel abroad.2. 主語為第三人稱單數(shù)(he、she、it等),則用"does"。例如:- He does not like spicy food.- She does her makeup every day before going to work.- It does not rain in the desert.3. 在疑問句中,要將助動詞置于主語之前,以構成疑問形式。對于第一人稱單數(shù)和第二人稱單數(shù)和復數(shù)的疑問句,直接使用“do”;對于第三人稱單數(shù),使用“does”來構成疑問句。例如:- Do you like coffee - Does she live in this city - Do they want to come with us 總之,使用do和does的核心是理解主語,在此基礎上判斷使用哪個詞。
