2、 not right to copy others homework.1）注意copy和write的区别：copy指把自己或是别人以写出的材料重新抄写一遍。write可指机械性的写，也可以指创造性的写信，写文件等。2）含有copy的习惯用语：copy down抄下来；记下来lend v.借出Could you lend me one hundred yuan?1)注意lend和borrow的区别：lend表示“借出”，是针对于主语来说的。borrow表示“借入”，也是针对语主语来说的。2）构成短语: lend sb. sth.=lend sth. to sb.含义是“把某物借给某人”。seco

3、nd n.第二；秒This is the second time I have met him.1）相关短语:second-hand二手的；旧的2）second作数词，含义是“第二”。3）second也有名词含义“秒”，是可数名词。bite v.咬My monkey doesnt bite.1） bite的过去式和过去分词分别是：bit和biten。2)bite常用于下面句型中：“bite +宾语 +介词 +身体的某一部分”,如：The snake bit him on the hand.蛇咬伤了他的手。appear v.出现；显现The sun appeared on the horizon

4、. 1）扩展词：appearance n.出现；到来2）appear是不及物动词，没有被动语态。hide v.隐藏The boy hid himself under the bed.这个男孩把他自己藏在床下。1）hide的过去式和过去分词：hid,hidden2)hidden除了是hide的过去分词形式外，还可以用作形容词，不一定具有被动意义。3）习惯短语：hide sth. from sb.含义是“隐藏”。cool adj.冷静的;凉爽的cook(v.做饭)cool (adj.凉爽的)Owning a cellphone can make students feel cool. 1）cool

5、作“凉爽的”讲时，反义词为warm“温暖的”。2）注意cold与cool的区别：cool“凉爽的”，给人一种舒适、惬意的感觉，反义词是warm。cold“寒冷的”，给人一种不舒服的感觉，反义词是hot。3）cool既可以用来指天气，也可以用来指人。4)cool作“冷静”讲时，构成以下短语：keep cool保持冷静；凉爽keep ones cool保持某人冷静lose ones cool失去镇定cool down冷静下来hurt v.伤害；疼His chest began to hurt. 1）hurt的过去式和过去分词分别是：hurt,hurt。2)hurt作动词讲时，既可以是及物动词，也可

6、以是不及物动词。作及物动词讲，是“伤害”之意；作不及物动词是“疼”的意思。wrong adj.失常的；错误的Whats wrong with her?她怎么了？1）注意be wrong with表示“出毛病”“有问题”“不顺心”。主语通常是something,nothing,what等。2）另外构成习惯用语：do wrong做错事，做坏事suggest v.建议，提出I suggest that you should go there by train.1）扩展词：suggestion n.建议2）同义词：advise v.建议2）后面通常加that引导的宾语从句。第二部分、短语讲解play

8、eft向右/左转turn around转过身turn into变成take a photo照相I will take a photo of the cute monkey.1）take a photo表示“拍一张照片”； take a photo of sb.表示“给某人拍一张照片”； take videos表示“拍录像”。2) take还可用于其他的固定搭配中：take away拿走； take sth. with sb.随身携带take medicine吃药come on赶快 Would you please come on!Well be late!come on常用在口语当中，在不同的

9、句子中有不同的意思。如：Come on,guys.You can do it!Oh,come on.Stop talking like that.save ones life挽救某人的生命Sometimes cellphones can be used to save peoples life.1）扩展词：safe adj.安全的 safety n.安全2）注意save的不同含义： save ones life挽救某人的生命save money攒钱第三部分、句子讲解Well, shes my friend, and its important for her.恩，她是我的朋友，而且这对她很重要

10、。Its important for sb.意思是“对某人很重要”，Its important for sb. to do sth.的意思是“做某事对某人很重要”。e.g.Its important for him to pass the exam. 对他来说通过考试很重要。Its very important for us to study a foreign language well. 对我们来说，学好一门外语很重要。拓展：Its + 形容词 + for sb. to do sth. 做某事对来说此句型中的it是形式主语，真正的主语是后面的动词不定式短语。这是一个非常实用的句型，希望同学

11、们务必掌握，在需要的时候信手拈来。e.g.Its good for people to do morning exercises. 晨练对人是有好处的。Its dangerous for children to cross the busy street. 小孩们穿越繁忙的街道是很危险的。If a snake bites you,take a photo with your mobile phone.如果一条蛇咬了你，用你的手机照一张照片。1)本句中if引导的是条件状语从句。2）本句的结构是“if.+祈使句”的结构。1）if有两个含义，一个是“是否”，一个是“如果”，而且都是充当引导词的作用。

12、2）take a photo表示“拍一张照片”。take a photo of sb.表示“给某人拍一张照片”。When they knew the kind of snake,they could give Mr.Jackson the right medicine,and he left the hospital the next day.当他们知道这种蛇之后，他们能给杰克逊合适的药物，然后第二天他就出院了。本句是一个由and连接的并列句。注意left是leave的过去式形式。leave the city表示“离开这个城市”，而leave for the city表示“前往这个城市”。If

13、 you want to send your recording by email, connect the recorder to your computer.如果你想通过电子邮件发送录音的话，把录音机和你的电脑连上。（1）by email 通过电子邮件注意类似短语:by bus/ train/ bike/ plane/ air/ car“乘公共汽车/火车/自行车/飞机/小汽车”名词前没有冠词。当具体到某一交通工具时，前面要加冠词或形容词性物主代词，并且不用by.e.g.I went there by bike.=I went there on my bike. 我骑自行车去的那儿。Tom

14、went to school by car. Tom搭出租车上学。Tom went to school in his fathers car. Tom坐爸爸的车上学。（2）connect在这里表示“连接”，后面可以接介词to或者with，变为connect sth. to/ with e.g.Could you connect the printer to the computer? 你能将打印机连在电脑上吗?Will you connect this wire to the television?你把这根电线和电视机连上好吗？Connect the gas stove with the ga

15、s pipe.将煤气炉和煤气管接起来。第四部分、语法讲解If 从句（1）1if从句的构成我们会用汉语说“如果想去的话，请告诉我”、“如果你想了解更多的内容，请打电话给我们老师”，其中“如果”后面可以有主语，也可以没有。那么用英语该如何说呢?首先看几个例子：If you want to go, please tell me.如果想去的话，请告诉我。If you want to know more about it, please telephone our teacher.如果你想了解更多的内容，请打电话给我们老师。If the green light isnt on, wait a minut

16、e.如果绿灯还没亮，就等一下。从例句中可以看出，if所引导的是一个完整的句子，一定要有主语。2if从句的位置本模块我们接触的都是“if从句+祈使句”的句子。if引导的条件从句表示“如果”，条件状语从句可置于祈使句前或后，如上面的例句；也可以放在主句之后。e.g.Print the photo if you like it. Look at our website if the camera does not work.Tell him to make a phone call to me if he comes here tomorrow.3注意if引导的条件状语从句和宾语从句的区别if可以用

17、来引导宾语从句也可以用来引导条件状语从句，主要是要弄清if引导从句的时态。if在引导宾语从句时，意为“是否”。要根据实际情况来确定时态，而if在引导条件状语从句时意为“如果，假设”，要用一般时代替将来时。e.g.I want to know if he will come here tomorrow. if在上句引导的是宾语从句，从句中有很明显的表将来的时间状语tomorrow，所以if从句要用一般将来时。e.g.If it rains tomorrow, well put off the sports meeting. if在上句引导的是条件状语从句，尽管从句中也有表将来时的时间状语tomo

18、rrow，从理论上讲也应该用一般将来时，但是在if引导的条件状语从句中要用一般现在时代替一般将来时，故从句谓语动词用rains而不用will rain. 用if连接下面的句子1）She didnt know the way to the station.Ask someone around.答案：If she didnt know the way to the station，ask someone around.2）You are hungry.Go to the KFC.答案：If you are hungry，go to the KFC.3）You dont understand the

19、 article.Ask your teacher.答案：If you dont understand the article，ask your teacher.4）You dont know the word.Look it up in the dictionary.答案：If you dont know the word，look it up in the dictionary.5）We get lost.Ask the policeman for help.答案：If we get lost，ask the policeman for help.Tips.不规则动词巧记1.巧记AAA型动

20、词英语中有些动词的动词原形、过去式、过去分词三者一样，可以简记为：击中受伤让吐痰，（hithurtletspit)去掉花费读放砍。(ridcostreadputcut)2.巧记下列不规则动词（A）sinksanksunk 沉下swimswamswum游泳drinkdrankdrunk喝ringrangrung响beginbeganbegun开始singsangsung唱记忆方法：沉下游泳把水喝，铃响开始唱山歌。（B）lieliedliedlying说谎lielaylainlying躺；位于laylaidlaidlaying产卵，下蛋记忆方法：规则的说谎，不规则的躺，躺过就下蛋，下蛋又规则。（C
