Unit One 语法篇__________________________________________________________________________________ __________________________________________________________________________________重点掌握一般现在时的用法重点语法：客观事实和真理：A.现在经常性的动作或状态B.一、一般现在时的用法一般现在时表示习惯性、经常性、反复性的动作或存在的状态。
“习惯性、经常性、反复性”是一般现在时的三大特性，它不表示特定时间内发生的事。
/month/year/…never,every day/week :always,usually,often, 二、时间状语标志词sometimes,：三、一般现在时的构成Be动词构成的一般现在时；实义动词构成的一般现在时四、谈谈“主语为三单，其后动词s添”可以简单叙述为“主在一般现在时中，当主语为第三人称单数时，谓语动词要用第三人称单数形式。
s语为三单，其后动词添”。
何谓第三人称单数？用一句话概括就是“非你、非我、非复数”，he, she, it, my father, my mother, my sister, our English teacher, Tom, Mike, Liu Jia, 如China, my book, etc.五、动词第三人称单数变化规则动词第三人称变化的规则与可数名词复数变化的规则相同。
-s。
规则一、一般在词尾加 looks, puts. reads, sees, skis等。
如：结尾的加-es规则二、以。
-o, -s, -x, -sh, -ch goes, does, misses, passes, mixes, fixes, pushes, wishes, watches, teaches,等。
如：注意一定是辅音字母加y。
为i，再加-es才变，若是元音字y规则三、以辅音字母加y结尾的，变母加y，则直接加-s。
如：fly → flies, try → tries, fry → fries, copy → copies, buy → buys,1pays says, plays, pay enjoy →say enjoys, →play →→六、一般现在时的句子转换提到主语的前面)等等（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 not变成一般疑问句;在be动词或情态动词后面加变成否定句.例：She is a student.①陈述句：一般疑问句→ Is she a student?否定句→ She is not a student.I can swim.②陈述句：否定句→ I can not swim.一般疑问句→ Can you swim?does以及复数动词，也没有情态动词时，则在主语前加助动词do (you,), be（2）当句子中即没有), ）变成一般疑问句；在主语后谓语动词前加助动词don't（I,you,以及复数（单数she,he,it 变成否定句，助动词后的动词要变成动词原形。
例：）doesn't（单数she,he,itWe get up at 7:00 every morning. ①陈述句：一般疑问句→Do you get up at 7:00 every morning?very morning. 否定句→We don't get up at 7:00 eShe has a little brother.②陈述句： a have little brother.否定句→ a 一般疑问句→ Does she have little brother?

是第二人称，所以用do1.travel是动词，所以我们必须用助动词来构成一般疑问句，来构成一般疑问句。
2.Mary 是第三人称单数，借助助动词does 3.。
来构成疑问句的，所以用什么问，就用什么答，故选问句中是用助动词doC does,do4.做作业是动词，所以借助助动词或者根据B后面的内容可知选。
because是第三人称单数，所以用e,your brother是动词，所以我们必须用助动词来构成一般疑问句在借助助动词后，原来的动词要还原。
故选does,B。
