Do you like biscuits? Yes, I do. I like biscuits,but I dont want one. Do you like beer? Yes, I do. I like beer ,but I dont want any. 一般现在时的基本用法： 1. 描述现在的事实或状态，常用be等表示状态的动词。 There flowers are very beautiful. I am thirteen. / We are students. 2. 表示经常性的习惯性的动作，常与表频度的 时间状语连用。 （always ,often ,usually ,sometimes）： He goes to school at 8 o’clock everyday. He reads English everyday. 3.表示主语具备的性格、能力和特征。 I don’t want so much. Grammar 4. 描述客观的事实或普遍真理： The sun rises on the east. The earth moves around the sun. 5. 口语的时候也可以代替将来时（come go leave arrive start get stay 等单词）： The meeting starts at 5 o’clock. 会议将在5点中开始 注意和be going to的区别。 We are going to a meeting at 5 o’clock. 肯定句： She is a teacher. 这第一种形式就是已经学过的S+be的系表结构，不再举例。 I like beef. He likes the beef. 第三人称单数要进行-s –es的变化。 否定句与疑问句： I don’t like beef. Do you like beef? Yes, I do. No, I don’t. What do you like? He doesn’t like beef. Does he like beef? Yes, he does. No, he doesn’t. What does he like? What does he do? 他在干什么？ 1. 由此可见，一般现在时中，否定句与疑问句要用助动词do来提问（第三人称用does）。 2. 注意的是，如果句子中有了助动词does了，那么实义动词本身不变化。 3. 注意这个does的发音。 动词的变化：当主语是第三人称单数时，动词需要变化，规则与名词的复数类似： 1. 一般动词加 –s 2. 以s/sh/ch/x/z 加-es，如：push、pass、catch、fix、buzz 3. 以辅音+y结尾，把y变i再加-es，如：study、cry 4. 以辅音+o结尾加es，如：do、go。 练习答案?
