行为动词的一般现在时（Ⅰ）

   行为动词指的是描述实际动作的动词,如go,have,dance等这样的表示行为动作的动词。行为动词的一般现在时具体用法:

(1)要描述经常性的习惯性的或反复发生的动作。如:
  I do my homework at 8 o'clock.
  The students have lunch at 12 o'clock.
  Lucy and I go to school at nine.

(2)表示主语具备的性格和能力等。如:
   You speak English well.
   I like maths very much.

(3)表示普遍真理和客观规律。如:
   The moon goes around the earth.

  在行为动词作谓语的句子中,当句子主语为第一、二人称或表示复数概念的名词或代词时:
   肯定句:“主语+行为动词原形+其他”
   否定句:“主语+don't+行为动词原形+其他”
   一般疑问句:“Do+主语+行为动词原形+其他”

注意:（don't是do not的缩写,do是助动词,没有词义,但不能省略）。如:
    They don't have an English class today.
    We go to school from Monday to Friday.We don't go to school on the weekend.
