一般现在时的用法1）表示经常性、习惯性的动作或存在的状态。
通常与副词sometimes, often, usually, always, everyday （year, month ）, once （twice, three times） a day,等等频率畐寸词（时间状语）连用。
.They usually go to school by bike.I take the medici ne three times a day. 实义动词表示“动作”She helps her mother once a week.Mary' s father is a policema n.There are 50 stude nts in my class. Be 动词表示“状态”He is very busy now.be、do不能放一起，如果非要放一起，do后要加ing,变成现在进行时。
2）表示主语的特征、性格、爱好等。
.I work hard.I like watching TV.3）表示客观真理.There are seve n days in a week.The moon moves round the earth.The sun rises in the east and sets in the west every day.Tomorrow is Tuesday.一般现在时的句子转换：三、一般现在时的结构：主语+谓语+其它”，有时为了起强调作用，时间状语也可提前.三单变化：1）多数在动词后+ s：play —plays like —likes ask---asks work-works get---gets stay-stays2）以字母s, x, ch, sh或o结尾的动词，+-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+-es.try---tries study-studies cry---cries fly---flies 不规贝U变化：be---- is are have----has做题时常见错误如下：1）、be 动词与行为动词同时出现在句子中例：We are plant （plant） the trees in spring. 答案：plant2)、单三人称形式易出错例： 1 He plaies (play) football very well.2 Danny gos (go) to school at 7:10.答案：1 plays 2 goes解析：1以辅音字母加y结尾的动词变单三人称形式才能把y换成i再加es；2 与名词变复数不同，变单三人称形式以o 结尾的词要加es.3)、在句式变换时易出错例： 1 Does Jenny has (has) a good friend2 Brian doesn 't lives (not live) in China.答案： 1 Does have 2 doesn 't live解析：口诀：“见助动，用原形”。
此口诀用于一般过去时态中。
. He didn't go home yesterday.4）、对do 的理解易出错例：We don't （not do） our homework in the afternoon.答案：don't do解析：do 是一个比较难理解的词，它有三个含义:a）是所有行为动词的总称；b）是助动词，无实义；c）是一个具体的行为动词做，干” 此句中给出的do 指做，干” not指把此句变为否定句，故须在do前加助动词don'。
5)、对主语的数判断有误例：Li Ming with me are (be) in Beijing.答案: is解析:表面一看是“我和李明两个人在北京”，但with 在此做伴随状语，不能做主语，故用is.一. 选择填空。
