爱华网一般现在时讲解及练习
一． 用法
1 )它表示经常性、习惯性的动作或存在的状态。
e.g. I goto school on foot.
He is very busy now.
2)它表示主语的特征、性格、能力、爱好等。e.g.I work hard. He workshard.
I like watching TV. Shelikes watching TV.
3)它表示客观真理
e.g. There are seven days in a week.
The moon moves round the earth.
其结构按正常语序，即“主语+谓语+其它”。
二．其疑问句否定句变化可分为两种情况，实意动词和be动词
实意动词又分为两种：1)表示动作，一般人称作主语的，变否定句须在动词前加助动词don’t；变一般疑问句须在句首加助动词do。E.g. Theyhave lunch at 12:00. They don’t have lunchat 12:00. Dothey have lunch at 12:00?
2）单三人称做主语的，变否定句须在动词前加助动词doesn’t；变一般疑问句须在句首加助动词does。
E.g. Jennyspeaks English very well.
Jenny doesn’t speak English very well.
Does Jenny speak English very well?
3）含有be动词的要在be上做变化.
E.g. Danny is a good student.
Danny isn’t a good student.
Is Danny a good student?
三、第三人称单数时，英语动词的变化规则
动词，在英语众多词汇中堪称变脸的高手，遇到不同的人称、数和时态，它总会以不同的面孔登场。一下是一般现在时态中当主语是第三人称单数英语动词的变化规则。
主语为第三人称单数的动词变化主要体现在词尾的变化上，其规律大体有三点：
1.一般情况下，直接在动词词尾+s ，例如：get→gets;take→takes
2.以s, sh, ch, x, o 结尾的动词，在词尾+ es，
例如：teach→teaches; fix→fixes;go→goes
3.以辅音字母+ y 结尾的动词，变y 为，再+ es，
如：study→studies; try→tries
除上述规律外，还应注意下面三点：
1.动词have ，遇到主语是第三人称单数时，要用has动词be的第三人称单数形式是is。
2.含有动词第三人称单数形式的句子变否定句时，要用doesn't + 动词原形，如：
He goes to schoolat six in the morning. (变否定句)→He doesn't go to school at six in themorning.
3.对含有动词第三人称单数形式的句子提问时，要用助动词does，如：Shegoes home at five every day. (对划线部分提问)→When / What time does she go home everyday?
综上所述，只要我们洞悉了英语动词第三人称单数形式的变化规则，在一般现在时的句子中，我们都能从容应对，客随主“变”了。
大家都知道，在一般现在时中，当主语是第三人称单数时，谓语动词要用第三人称单数形式，即常在动词原形-s或-es。但有些同学们对于哪些主语是第三人称单数还不十分清楚，现归纳总结如下：
一）、人称代词he, she, it是第三人称单数。如：Helikes watching TV. 他喜欢看电视。
She has lunch attwelve. 她十二点吃午餐。looks like a cat. 它看起来像只猫。
二）、单个人名、地名或称呼作主语；是第三人称单数。如：
①Han Mei looks like her mother. 韩梅看起来像她的母亲。
②Beijing is in China. 北京在中国。
③Uncle Wang often makes cakes. 王叔叔经常做蛋糕。
三）、单数可数名词或"this / that / the+单数可数名词作主语时，是第三人称单数。如：
①A horse is a useful animal. 马是有用的动物。
②This book is yours. 这本书是你的。
③That car is red. 那辆小汽车是红色的。
④The cat is Lucy's. 只猫是露茜的。
四）、不定代词someone, somebody, nobody, everything,something等及指示代词this,that
作主语时，是第三人称单数。如：
①Everyone is here. 大家到齐了。
②There is something wrong with the watch.这块手表有毛病。
③This is a pen. 这是一支钢笔。
④That is an eraser. 那是一块橡皮擦。
五）、不可数名词作主语时为第三人称单数。如：
①The milk is in the glass.牛奶在玻璃杯里。
②The bread is very small. 那面包很小。
六）、当数字或字母作主语时，看作第三人称单数。如：
①"6" is a lucky number. "6"是个吉利数字。
②"I" is a letter. "I"是个字母。
四、其时间状语为often、usually、always、sometimes等频率副词，onSaturdays、in themorning(afternoon evening) 、everyday 等。
五、做题时常见错误如下：
一）be动词与行为动词同时出现在句子中（不是每个英文句子都需要be动词）
例：We areplant(plant) the trees in spring.
答案：plant解析：学生往往会用汉语的思维方式去翻译，就成了“我们是在春天植树”。这是学习英语最忌讳的，要看语法是不是正确，在英语中，be是表状态，do是表动作，两种动词不能同时出现在句子中，可记住如下口诀：“英汉语言有差异，be、do不能放一起。”
二）、现三单的动词变化错误：
例：1 Heplaies (play) football very well.
2Danny gos (go) to school at 7:10.
答案：1plays 2goes
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.
三）、在句式变换时易出错
例：1 DoesJenny has (has) a good friend?
2Brian doesn’t lives (not live) in China.
答案：1Doeshave2 doesn’t live
解析：单三人称做主语的一般现在时做句式变化时，可记住如下口诀：“见助动，用原形”。此口诀也可推广用于一般过去时态中。e.g.He didn't go home yesterday.
四）、对do的理解易出错
例：Wedon’t (not do) our homework in the afternoon.
答案：don’tdo 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’t。
五）、对主语的数判断有误
例： LiMing 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.LiMingand me are inBeijing.
