语法专项易错点练习
现在进行时(be + v-ing)与一般现在时(第三人称单数)
2026—2027学年上学期英语四年级上册(人教版PEP)
【语法易错点速览】
(1) 现在进行时结构:主语 + be 动词 + 动词-ing,表示现在正在进行的动作;常见标志词有 Look! / Listen! / now / right now。如 Chen Jie is making the bed.(陈杰正在铺床)。
(2) be 动词随主语变化:I 用 am;he / she / it 或单数(Chen Jie, a cook)用 is;we / you / they 或复数(students, Binbin and John)用 are。口诀:I am, he/she/it is,单数 is、复数 are。
(3) 现在分词构成:一般直接加 -ing(sing→singing,clean→cleaning,play→playing);以不发音的字母 e 结尾,要去 e 再加 -ing(make→making,drive→driving)。
(4) 不能漏掉 be 动词:He is cooking.(√),不能说 He cooking.;be 动词还要与主语一致:They are cleaning.(√),不能说 They is cleaning.。
(5) 一般现在时第三人称单数:表示经常发生的动作或客观情况,标志词 often、every day;主语是 he/she/it 或单数时,动词加 -s/-es(help→helps,take→takes,clean→cleans,cook→cooks)。
(6) 区分两种时态:看到 Look! / now / right now 用现在进行时(be + doing);看到 often / every day 用一般现在时(三单动词加 -s)。注意 There is + 单数名词,There are + 复数名词;否定祈使句用 Don’t + 动词原形。
