一般现在时变否定句的规则

2、2 Jim does his homework 、否定句 Jim doesnt do his homework 、例 3 Marry goes to school 、否定句 Marry doesnt go to school 、如果主语不就是第三人称单数时,只 需在实义动词前加dont 、例 1 I teach English 、否定句 I dont teach English 、例 2 They go to school 、否定句 They dont go to school 、例 3 We sing a song 、否定句 We dont sing a song 、(c) 含有情态动词的句
