1、 一般现在时1.概念：一般现在时表示经常的、习惯性的动作或存在的状态。2. 一般现在时的构成一般现在时的构成主要有两种形式：(1)be 型：句子的谓语动词只有 be(am，is 或 are)：a.肯定句中，只出现 be，如： I am a student.我是一名学生。b.否定句中，要在 be 后面加 not，如： She isnt a teacher.她不是教师。c.一般疑问句，要将 be 放在句子开头(注意句首字母大写) ，句尾用问号，答语用 Yes，主语+be.或 No，主语 +be+not.如：Are you ready?你准备好了吗? Yes，I am.是的，我准备好了。(No，Im
2、 not.不，我没准备好。)(2)实义动词型 ：句中的谓语动词为实义动词(也叫行为动词) ：a.肯定句中，只出现实义动词，如：I get up in the morning.我早晨起床。b.否定句中，要在实义动词前面加 do(does)+not，do(does) 作助动词，本身无意义，常与not 缩写成 dont(doesnt)，如： I dont like vegetables.我不喜欢蔬菜。c.一般疑问句，要在句子开头加助动词 Do(does)，句尾用问号，简略答语用 Yes，主语+do(does).或 No，主语+do(does)+not.如：Do you like oranges?你喜
