Unit One 语法篇 ‎ __________________________________________________________________________________‎ ‎__________________________________________________________________________________‎ ‎ 重点掌握一般现在时的用法 重点语法：‎ 一、一般现在时的用法：A.现在经常性的动作或状态B.客观事实和真理 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。 二、时间状语标志词:always,usually,often, sometimes, never,every day /week /month/year/…‎ 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” 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。可以简单叙述为“主语为三单，其后动词s添”。何谓第三人称单数？用一句话概括就是“非你、非我、非复数”，‎ 如he, she, it, my father, my mother, my sister, our English teacher, Tom, Mike, Liu Jia, 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。 规则一、一般在词尾加-s。‎ 如：looks, puts. reads, sees, skis等。 规则二、以-o, -s, -x, -sh, -ch结尾的加-es。‎ 如：goes, does, misses, passes, mixes, fixes, pushes, wishes, watches, teaches,等。 规则三、以辅音字母加y结尾的，变y为i，再加-es。注意一定是辅音字母加y才变，若是元音字母加y，则直接加-s。 如：fly　→　flies,　try　→　tries,　fry　→　fries,　copy　→　copies, buy　→　buys,　‎ ‎ enjoy　→　enjoys,　play　→　plays,　say　→　says,　pay　→　pays 六、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一般疑问句;在be动词或情态动词后面加not变成否定句.例：‎ ‎①陈述句：She is a student.‎ 一般疑问句→ Is she a student? 否定句→ She is not a student.‎ ‎②陈述句：I can swim.‎ 一般疑问句→ 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), 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。例：‎ ‎①陈述句：We get up at 7:00 every morning.‎ 一般疑问句→Do you get up at 7:00 every morning?‎ 否定句→We don’t get up at 7:00 every morning.‎ ‎②陈述句：She has a little brother.‎ 一般疑问句→ Does she have a little brother? 否定句→ She doesn’t have a little brother.‎ ‎1._______________you often travel for car?‎ ‎ A.Do B.Are C.Is D.Does ‎2.___________Mary go online everyday?‎ ‎ A.Do B.Are C.Is D.Does ‎3.--Do over 50% of fire start in bedroom? ---__________________.‎ ‎ A.Yes,they are B.No,they aren’t C.No,they don’t D.Yes,they start ‎4.My sister________her homework at home because she does it at school.‎ ‎ A.isn’t do B.doesn’t do C.does D.do ‎5.How________your brother___________the Internet to make phone?‎ ‎ A.do; use B.does; use C.does; uses D.does; using 解析：‎ ‎1.travel是动词，所以我们必须用助动词来构成一般疑问句，you是第二人称，所以用do。‎ ‎2.Mary 是第三人称单数，借助助动词does来构成一般疑问句。‎ ‎3.问句中是用助动词do来构成疑问句的，所以用什么问，就用什么答，故选C。‎ ‎4.做作业是动词，所以借助助动词do或者does,根据because后面的内容可知选B。‎ ‎5.use是动词，所以我们必须用助动词来构成一般疑问句,your brother是第三人称单数，所以用does,在借助助动词后，原来的动词要还原。故选B。‎ 答案： 1. A 2.D 3.C 4. B 5.B 基础演练 一、写出下列动词第三人称单数的变化形式。‎ ‎1.be________ 2.have_______ 3.come______ 4.go_________ 5.stay__________ ‎ ‎6.teach______ 7.write________ 8.take_______ 9.study______ 10.watch_______‎ ‎11.fly_______ 12.play________ 13.run_______ 14. do_______ 15.like_________‎ ‎16.carry_____ 17.guess_______ 18.finish______ 19.snow______ 20.wash_______‎ 二、用括号中所给词的适当形式填空。‎ ‎1．The buses ______ (use) a lot of oil.‎ ‎2．Each of us ______ (have) strong points and weak points.‎ ‎3．My daughter ___ (watch) TV every day.

However, you can also find many weather signs (预兆) among animals, because they have developed (发达的) senses. Drops in air pressure (压力) have an influence on small animals in many ways. Mice and deer are good weather indicator (指示信号). People who spend a lot of time outdoors have found that, before a storm, field mice come out of their holes and run around. Deer leave high ground and come down from the mountains.‎ ‎ Birds are especially good weather indicators because they also show the effect(影响) of a pressure drop in many ways. For example, some birds make more noise than usual and will fight about a piece of bread. Other birds sing just before a storm. It seems they know they won’t get another chance for an hour or two. Birds also try to find safe places before a storm. You will sometimes see birds staying in trees or coming together on a wire (电线) close to a building. Before storm low pressure makes the air so thin that it’s difficult for birds to fly.‎ ‎ It is unusual to see many birds flying overhead in the summer time. Watch for other weather signs if you see this. If they fly in the wrong direction, they may be flying before a storm. ‎ ‎ By paying attention to some important signs in nature carefully, we can get ready for any kind of weather.‎ ‎5.
