4 初二学过的六大时态一、一般现在时概念：经常、反复发生的动作。时间状语：always, usually, often, sometimes, every week (day, year, month), once a week, on Sundays, etc.基本结构：be动词；He is tall.行为动词.其他人称用动词原形。I/We/You/You/They+V原。 主语是第三人称单数时用动词的“单三形式”， 动词三单形式的变化规则：1.（1）多数直接在动词词尾加-s. play plays like likes ask-asks work-works get-gets call-calls（2）以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es. watch-watches wish-wishes do-does go-goes fix-fixed,discuss-discusses （3）以“辅音字母加 - y”结尾的动词，要先变y为i再加-es. try-tries study-studies cry-cries fly-flies2. 不规则变化：be- is have-has3. 一般现在时的句子转换：（1）变一般疑问句：当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等)提到主语的前面.（2）变否定句：在be动词或情态动词后面直接加not变成否定句. (be后not莫忘记)例：陈述句：She is my sister.疑问句 Is she your sister? Yes, she is ./ No, she isnt.否定句 She is not my sister.陈述句：I can play soccer.疑问句 Can you play soccer? Yes,Ican./ No, I cant.否定句 I can not /cant play soccer.（3）当句子中没有be动词，也没有情态动词时，变一般疑问句时，在主语前加助动词do (I, we, you,以及复数), does（第三人称单数she,he,it等）变成问句；（4）变否定句时，在主语后谓语动词前加助动词dont, doesnt变成否定句，切记：助动词后的动词则还原成动词原形。例：陈述句：We get up（起床） at 7:00 every morning.疑问句Do you get up at 7:00 every morning?否定句We dont get up at 7:00 every morning. 陈述句：She has a brother.疑问句 Does she have a brother? 否定句 She doesnt have a brother.巩固练习题： 一、按照要求改写句子1 She enjoys swmiming very much .
