资源简介

语法：一般现在时
1.表示：
（1）经常性，规律性，习惯性：“经常发生的动作或者有规律做的事情”，比如每天起床、吃饭、上学，一周去几次超市或新华书店等；
I always go to school by bus. 我总是坐公交车去学校。
She has lunch every day. 她每天吃午餐。
真理性：有些动作或状态是永恒的，比如长江向东流、地球绕着太阳转，比如谚语中举的事例、文学作品中描绘的事例，像“好马不吃回头草”等等事物存在的状态。
The earth goes around the sun. 地球绕着太阳转。
存在：一直以某种状态存在，比如头发是黑的，家里有兄弟姐妹等。
Tom has two sisters. 汤姆有两个姐妹。
My hair is long. 我的头发长。
2.具体运用：
（1）表示经常的或习惯性的动作，常与表示频率的频率副词连用。　　
①模糊频率副词
都是表示事情发生频率的副词，也是不准确地说某事在一段时间内发生的次数。
always 总是 usually 通常 often 经常
sometimes 有时 hardly =seldom 几乎 never 从来不
我们按照频率发生的高低，可以将这几个词排列为
always > usually > often > sometimes > hardly=seldom > never。
这些模糊频率副词在用的时候放在主语后， be 动词后，行为动词前。
I always go to school on foot. 我总是走路上学。
He is often late for school. 他经常上学迟到。
②精确的频率副词
以下这些频率副词可以准确地表达事情发生的频率。
一次 once 两次 twice 三次 three times
四次 four times 五次 five times 六次 six times
注意：在记忆时，我们只要记住once（一次）和twice（二次）就可以了。其他发生次数只要用“数字＋times”来表达就可以了。
其他的表达法：
every day 每天 once a week 一周一次 twice a month 一 个月两次
four times a year 一年四次 once two weeks 两周一次 twice three months 三个月两次
这些精准的频率副词在用的时候一般放在句子末尾。
例如：
I drink milk and eat vegetables every day.
我每天喝牛奶，吃蔬菜。
I exercise once a week.
我每周锻炼一次。
I eat McDonald’s twice a month.
我一个月吃两次麦当劳。
I visit my grandmother four times a year.
我一年去看奶奶四次。
结构：
①当主语不是第三人称单数时： 　　
肯定句 ：主语+动词原形+其它。
I like this blue sweater. 我喜欢这件蓝色的毛衣。
否定句 ：主语+don't+动词原形+其它。
I don’t like this blue sweater. 我不喜欢这件蓝色的毛衣。
（在主语后加上 don't 变为否定句）
一般疑问句： Do+主语+动词原形+其它？
Do you like this blue sweater Yes, I do. / No, I don’t.
你喜欢这件蓝色的毛衣吗？ 是的，我喜欢; 不，我不喜欢。
（在主语前加上Do， 变为疑问句）
②当主语是第三人称单数时： 　
肯定句：主语+动词第三人称单数形式+其它。
Tom likes English. Tom喜欢英语。
　　
否定句：主语+doesn't+动词原形+其它。
Tom doesn’t like English. Tom不喜欢英语。
（在主语后加 doesn't，变为否定句，doesn't后的动词还原成原型）
一般疑问句：Does+主语+动词原形+其它。
Does Tom like English？ Yes, he does. / No, he doesn’t.
Tom喜欢英语吗？ 是的，他喜欢；不，他不喜欢。
（在主语前加 Does，变为疑问句，does后的动词还原成原型）
注意：第一人称I / we提问时会变成二人称you。
第三人称单数口诀
人称 单数 复数
第一人称 I(我) we(我们)
第二人称 you(你) you(你们)
第三人称 he/she/it(他/她/它) they(他们)
4.第三人称单数的变化规律：
一般情况 +s look—looks
以s、x、ch、sh和o结尾 +es go—goes do--does watch-watches pass-passes fix-fixes wash-washes
以辅音字母y结尾 变y为i +es study—studies
以元音字母y结尾 +s play—plays
特殊情况 不规则 have—has
