There are seven days in a week. The moon moves around the earth.一般现在时的句型结构：（1）句中有be（am,is,are）,在be上做变化:肯定句：主语+be+其它 eg. Danny is a good student.否定句：主语+be+not+其他 eg. Danny is not a good student.一般疑问句：Be+主语+其他 eg. Is Danny a good student? （2）句中有实意动词，如work, go, get, help, study, play等表示主语的动作肯定句：主语+谓语动词+其他 eg. I work hard at school.否定句：主语+dont或doesnt+谓语动词原形+其他 eg. I dont work hard at school.疑问句：Do或Does + 主语+ 动词原形+其他 eg. Do I work hard at school?E.g. They have lunch at 12:00. They dont have lunch at 12:00.Do they have lunch at 12:00? 注意：单数第三人称做主语时，谓语动词要用单三形式，变否定句须在动词前加助动词doesnt;变一般疑问句须在句首加助动词does。E.g. Jenny speaks English very well.Jenny doesnt speak English very well.Does Jenny speak English very well?动词第三人称单数的变化规则如下：（1）直接在动词词尾加-s.ask-asks work-works get-gets stay-stays play plays like likes（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 fix-fixes do-does go-goes pass-passes（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-flies（4）不规则变化： have-has一般现在时态的时间状语为often、 usually、 always、 sometimes等频率副词，on Saturdays、 in the morning(afternoon evening) 、every day 等。常见错误：be动词与实意动词同时出现在句子中例：We are plant (plant) the trees in spring.（误） 正解：We plant (plant) the trees in spring.解析：在英语中，be是表状态，do是表动作，两种动词不能同时出现在句子中，可记住如下口诀：“英汉语言有差异，be 、do不能放一起，仔细琢磨细分析，语法千万要牢记。”一般现在时态练习一般现在时态的时间状语为often、 usually、 always、 sometimes，on Saturdays、 in the morning/afternoon/ evening 、every day、every week 等。I用所给词的正确形式填空1.
