      Language points
      1. You watch TV all the time and ...
        all the time(在该段时间内)一直;向来, 一向;时时刻刻;每时每刻
        e.g. I do this all the time. 我一直是这么做的。
        This happens all the time. 这种情况是时时发生的。
      2. I’m just as tired as you are!
        as ... as 意为 “和……一样” ,表示同级的比较。使用时要注意第一个as为副  
        词,第二个as为连词。其基本结构为:as + adj./ adv. + as。
        e.g. This film is as interesting as that one. 这部电影和那部电影一样有趣。
        Your pen writes as smoothly as mine. 你的?#30452;适?#20889;起来和我的一样流畅。
        as … as 的否定形式为 “not as/so + adj./adv. + as”。
        e.g. He didn’t act as well as you. 他表?#20540;貌?#22914;你好。
      3. For one week, she did not do any housework, and neither did I.
        neither 用作副词,作“也不”解释,放在句首,表示前面否定的内容也适用于  
        另一个人或物,句?#26377;?#37319;用部?#20540;?#35013;。此时也可用nor替换 neither 使用。
        例如:
        — I don’t like this dress. 我不喜欢这件连衣裙。
        — Neither / Nor do I. 我也不喜欢。
      注意:neither 之后的主语要置于助动词或系动词之后。
        neither 用作代词,表示“两者都不,双方均不”。例如:
        He answered neither of the letters. 他两封信都没回。
        — Which one would you like? 你喜欢哪一个?
        — Neither. 两个都不喜欢。
        also, too, either, neither 的用法
      一、 also 是比较正式的用语,语气较庄重。它通常放在句中,位于?#24418;?#21160;词之
           前,连系动词之后; 如有助动词或情态动词,一般放在助动词或情态动词   
           之后。例如:
           Peter also has two brothers. 彼得也有两个?#20540;堋?
           I am also a student. 我也是一名学生。
           Mrs. Green can also sing the song in Chinese. 格林夫人也能用汉语唱这首歌。
      二、too 是普通用词,多用于口语,语气较随便。一般用在肯定句中,放在句
          末。例如:
           I’m in Row 1, too. 我也在第一排。
      注意:also和too一般都用于肯定句,很少用于否定句。
      三、either 表示“也”时,一般只用于否定句,且置于句末。例如:
          I don’t know him. Tom doesn’t know him, either.
          我不认识他,汤姆也不认识他。
          If you don’t go there, he won’t go there, either.
          如果你不去那儿,他也不会去那儿。
      注意:either 本身没有否定的意义。所以多与 not 连用。
      四、neither 表示“两个都不?#20445;?#23427;作主语时,谓语动词常用单数。例如:
          Neither of you can do it. 你们两个都不能做这件事。

      fold one’s clothes, do the dishes, use one’s computer, take out the rubbish , make the bed, sweep the floor, stay out late, be angry with sb., take sb. for a walk, clean the living room, work on, come over, do the housework, get a ride
      导入目标
      学习运用情态动词的用法,并运用could有礼貌地提出请求及回答。
      自主学习
      Could you(please)+ V-原形?表示委婉地提出请求
      1. Could you please clean your room?
        Yes, sure. / Of course./ Certainly./All right.
      2. Could you please do the dishes?
        Sorry, I can’t. I have to do my homework.
        在表示请求帮助或请求允许的疑问句中,常用could代替can,以表示礼貌,委婉或不确定的语气,而can则不具备这些语气。这种情况下不能把could看作can的过去式。以上两句中用could是为了表示礼貌的请求。表示请求帮助或请求允许时,除了can, could之外,还可以用may,句子的表达方式也各有不同,可以用不同的方式来表示同一个概念。例:
      ① Could/Can/May I use your car for a day?     
      ② I wonder if I could use your car for a day?  
         对于①、②句所作允答可以各种各样,如同意可以说Yes或Sure或Certainly,还可说Yes, (do) please. 或Of course. (you may/can). 或Go ahead, please. 或That’s OK/all right; 如果不同意,可以说I’m sorry you can’t. 或I’m really sorry, but I have to use it today. 要避免说No, you can’t. 这样显得很不礼貌。否定回答通常用委婉语气。
      ③ Do you mind if I use your car for a day?
         对于句③所作回答可以说Never mind. /Not at all. 表“不介意”。不能用Yes. /Sure. /Of course. /Certainly.等。无论肯定还是否定应答中,要避免使用could,要用can或may。因为应答须用确定的语气。而could在表请求的问句中是为了表示礼貌或委婉语气,用在应答中则成了不确定语气,与情理不符。所?#26434;?#31572;中不说Yes, you could. 或No, you couldn’t. 而要说Yes, you can. 或Sorry. /No, you can’t.
      —Could I please use your computer?  
      —Sorry, I’m going to work on it now.
      —Well, could I watch TV?   
      —Yes, you can.
        Could I/you please …?表示一种有礼貌的请求或提议,其后连接原形动词,比Can you /I…?语气更委婉。类似句型有:
      Would you like + sth. / to do sth.?    
      May I + do sth.?   
      Shall we + do sth.?    
      Would you mind + sth. /doing sth.?
      What / How about + sth. /doing sth.?
      肯定回答有Sure. /Of course. / Certainly. /OK. /Great. / Well. / Good idea. / I agree. 等。否定回答有Sorry… / No, you can’t. 等。

      2. Skimming 意为“快速掠过,从中提取最容易取得的精华”。这种读法包含有原词的所有意思——快速读过去,取出读物中关键性的东西。因此,我们可以把这种读法理解为快速浏览课文,领会文章大意。一般而言,通过标题可知道文章的主题。对文章的首段和末段要多?#24188;?#24847;,以便发现作者的观点。

      1)According to Mr. Smith and Mrs. Miller, what are the personal cons and pros about kids doing chores?
      2)What do you think of it?
      4.Language points
      1)It is the parents’ job to provide a clean and comfortable environment at home for their children.
          此处代词it仅为形式上的主语, 真正的主语是to provide … for their children。我们?#37096;山獻t is one’s job (duty, …) to do something.视为一个固定的句型, 表示“做某事是某人的工作(职责等)”。如:
          It’s every teacher’s job to explain things clearly to the students.
      把东西给学生讲明?#36164;?#27599;一位老师应做的事情。
      provide 作动词,意为“ 提供?#36824;?#24212;”。
      provide sb. with sth.或provide sth. for sb.意为“为某人提供某物”。如:
      The movie theater provides us with good service.
      His school provided a house for him.
      汉译英。他们提供给他钱和衣服。
      They provided him with money and clothes.
      They provided money and clothes for him.
      2)And anyway, I think doing chores is not so difficult.
          反正我觉得干点家务也不难。
          anyway是一个副词, 若位于句首, 其后往往会有?#27721;?#23558;其与句子的其他内容隔开。anyway在此句中的作用是追加评论, 相当于汉语的“反正; 仍然; 依然”。如: Sam didn’t get the job, but he’s not unhappy because it didn’t pay well anyway.
      萨姆没有得到那份工作, 但他并没有闷闷不乐, 反正薪酬也不算高。
      anyway还可用来表示“不管怎样; 无论如何”之意。例如:
      It’s just a cold. But anyway, you should still see the doctor.
      这只不过是感冒, 但不管怎样, 你还是应?#27599;?#30475;医生。

      How to write a letter
      1. 信头:发信人地址和日期。
      这部分中有时可省去发信人地址,但一般要写日期。放在信纸的右上方。
      2. 称呼:对收信人的尊称。
      最普通的是Dear,但与Mr,Mrs,Miss等不同的是:Dear后一般用名字,而Mr,Mrs,Miss后不能单独用名字,而只能是姓或姓与名,比如:对John Smith的称呼,应该是Mr Smith,Mr John Smith或 Dear John.称呼后面可用?#27721;?#25110;者冒号。
      3. 信的正文。
      4. 结尾:发信人对收信人的谦称或敬语。放在信的右下方。
      这部分要特别注意英语习惯,不可根据汉语意思写?#29616;?#22914;“此致敬礼”、?#30333;?#24744;健康”之类的中国式的结尾语。常用的英语书信结尾语如下:
      写给同龄人或年长的朋友: Yours  sincerely,Sincerely yours,Yours等等。
      写给好朋友: Love,With love, Best wishes等等。
      写给亲戚:Love,With love,Your (ever) loving son(sister等等)。
