(完整版)四年级下册一般现在时.doc

一般现在时一般现在时的用法 (1) 表示经常发生或习惯性发生的动作时，用一般现在时态如：I often watch TV at home. (2) 表示客观的事实，用一般现在时态如：There are seven days in a week. 一般现在时的构成 当句子主语是I, we, they, you或复数名词时，动词用动词原形 当句子的主语是he, she, it或单数名词时，动词要用第三人称单数的现在式形态具体讲解：特别注意特征词( often usually always sometimes never seldom every+时间) 在句子中的标志作用，在做练习时最好把他们标记出来例子：She usually does her homework after dinner.注意区分好人称，第一，二人称和第三人称复数只需要用动词原形，他们的否定形式是“don’t+动词原形”，他们的疑问形式为“Do…+动词原形…?” 如果是第三人称单数就要作动词的变化例子：They go to work by bus on weekdays. They don’t go to work by bus on weekdays. Do they go to work by bus on weekdays?对于句子中的“doesn’t+动词原形” 及 “Do…+动词原形…?”分别是否定和一般疑问句的形式，一旦遇见“doesn’t” “do”这两个词时，动词必须还原。
