一般现在时：表示经常性，习惯性的动作或状态。
时间状语：
often 经常 | usually通常 | always 总是 | every每个 |
sometimes 有时 | seldom 极少 | never从不 |
|
结构： 动词原形 （第三人称单数-动词+s/es）。
第三人称单数变化：
ask---asks | work---works | get---gets | stay---stays |
(1)直接在动词词尾加-s.
(2)以字母s, x, ch, sh或o结尾的动词，在词尾直接加-es.
watch---watches | wish---wishes | fix---fixes | do---does |
go---goes | pass---passes |
|
|
(3)以“辅音字母加 - y”结尾的动词，要先变y为i再加-es.
try---tries | study---studies | cry---cries | fly---flies |
2.不规则变化：
be---- is are | have----has |
二、一般现在时用法
1. 表示经常性，习惯性,永久性的动作或存在的状态.
通常与副词sometimes, often, usually, always, every day (year, month ), once (twice, three times) a day,等时间状语连用。
They usually go to school by bike. | 他们通常骑自行车去上学。 |

Tomorrow is Tuesday. | 明天是星期二 |
三、一般现在时的句子转换：
(1)当句子中有be动词或情态动词时，则把be动词或情态动词(can,could等等)提到主语的前面变成疑问句;在be动词或情态动词后面加not变成否定句.
①陈述句：She is a student. | 疑问句→ Is she a student? 否定句→ She is not a student. |
②陈述句：I can swim. | 疑问句→ Can you swim 否定句→ I can not swim. |
(2) 当句子中即没有be动词，也没有情态动词时，则在主语前加助动词do (you,以及复数), does(单数she,he,it)变成问句;在主语后谓语动词前加助动词don’t(I,you,以及复数), doesn’t(单数she,he,it)变成否定句，助动词后的动词要变成动词原形。
①陈述句：We get up at 7:00 every morning. 我们每天早上7点起床。 | 疑问句→ 否定句→ |
②陈述句：She has a little brother. 她有一个小弟弟。 | 疑问句→ Does she have a little brother? 否定句→ She doesn’t have a little brother.
