一、一般现在时:
概念:表示现阶段经常或****惯发生的动作或存在的状态,或说明主语的特征。
用法:A) 表示现在发生的动作、情况、状态和特征。
B) 经常性****惯性动作。常及频率副词连用。
Eg.:He always helps others. (他总是帮助别人。)
C) 客观事实和普遍真理。
Eg. The earth turns round the sun.(地球绕着太阳转)
Light travels faster than sound.(光传播比声音快)
D) 表示一个按规定、计划或安排要发生的动作,(仅限于某些表示“来、去、动、停、开始、结束、继续”等的动词)可以及表示未来时间的状语搭配使用。常见的用法是:飞机、火车、轮船、汽车等定期定点运行的交通方式。
next train leaves at 3 o'clock this afternoon.
often does this shuttle bus run? (这班车多久一趟?)
E) 在时间状语从句中(以when, after, before, while, until, as soon as等引导)和条件状语从句中(以if,unless引导),用一般现在时代替一般将来时,句子可以有将来时间。
Eg.:Please ring me up as soon as you arrive in Germany.(你一到德国就给我打电话)
If it rains tomorrow,we will have to stay at home.(如果明天下雨我们就只好呆在家)
时间状语:always, usually, often, sometimes, every week (day, year, month…), once a week, on Sundays, etc.
基本结构:①be动词;②行为动词
否定形式:①am/is/are+not;②此时态的谓语动词若为行为动词,则在其前加don't,如主语为第三人称单数,则用doesn't,同时还原行为动词。
一般疑问句:①把be动词放于句首;②用助动词do提问,如主语为第三人称单数,则用does,同时,还原行为动词。
1 We often _____ (play) in the playground.
2 _____Mike_____ (read) English everyday?
3 Mike sometimes______ (go) to the park with her sister.
4 She usually _____ (watch) TV at 7 o’clock.
