一般现在时专题一般现在时：
  用法：表示站在“现在”这个时段叙述一般情况下发生的事情或状态, 经常性或习惯性的动作，在语法上我们往往都要使用到一般现在时（即使用一般现在时的语法），试体会下列句子时态，增加这方面的感悟和概念：

The man often goes to bed early in the evening.   这个男的晚上经常很早就睡觉。
  My father works in the hospital.   我爸爸在医院工作。
  Does your teacher like watching TV?  你老师喜欢看电视吗？
  Spring follows winter.  冬去春来。
  He is a good teacher.  他是位好老师。
  The boy is hot.  这个男孩子很热。（系表结构 be + 形容词）
  The boys often have parties in this music room. Listen! One of them is singing now. 那些男孩子经常在这个音乐房搞聚会。 听。他们中的一个人在唱歌。（前半句为一般现在时，后一句为现在进行时）
  语法：
（1）Be型句子（即句子里动词为am或is或are）以be为助动词，注意主谓搭配
  He is a teacher. → Is he a teacher? Yes, he is. / No, he isn’t → What is his job?
  I am  /  You are /  He is /  She is /  It is /  We are /  You are /  They are
  (2) 行为动词句子（do型）
   Ⅰ  人称为非第三人称单数，助动词为do (don’t).
My parents like watching TV in the evening. → Do your parents like watching TV in the evening? Yes, they do. / No, they don’t. → What do they do in the evening?
Ⅱ 若人称为第三人称单数，助动词为does (doesn’t), 肯定句(仅肯定句)时动词要有变化，否定句与疑问句动词不变（基本同名词复数变化）与上面的一组句子比较。
My parents like watching TV. → Do your parents like watching TV? Yes, they do. / No, they don’t. → What do they do in the evening?
My father likes watching TV. → Does your father like watch TV ? Yes, he does. / No, he doesn’t. → What does your father do in the evening?

good!very good!!
