(2)… times +性质名词 + of … 例如: this table is three times bigger than that one. 3.比较级前可以用 even, still,a bit /little,much, a lot, far, by far, no, any等修饰，表示程度。最高级前可以有序数词，by far, nearly, almost, by no means, not really ,not quite, nothing like等来修饰。例如: —is your father any better? 你父亲好些了吗？ —yes,much better.是的，好多了。 i’d like to buy the second most expensive laptop. 4.形容词副词比较的对象应该相同但不能相互包容。常用以下结构形式: 比较级 + than +any other + 单数名词；比较级 + than + anyone else；比较级 + than +any of the other +复数名词。 例如:  china is larger than any other country in asia /all the other countries in asia. the weather here is colder than that of huanggang. the computers made in our factory are better than those in your factory, 训练 1 you’d better go and buy some tomatoes for the dinner party, for you see, there are _ _ tomatoes left in the basket than i imagined. a. far more b. far fewer c. many more d. many fewer 答案: b 解析:far修饰比较级。 2 — are you satisfied with his work? — well, i’m afraid it couldn’t be __ . a. any better b. the best c. any worse d. the worst 答案: c 解析:否定词和比较级连用相当于最高级。 3 exercise is _ _ any other to lose unwanted weight. a. so useful a way b. as a useful way c. as useful a way d. such a useful way 答案: c 二、反身代词 （一）反身代词用法讲解
　　1、反身代词的构成
　　反身代词又称自身代词，有人称和数的变化。其中，第一、二人称的反身代词由＂形容词性物主代词 + 后缀-self（单数）/ - selves（复数）＂构成，第三人称的反身代词由＂人称代词的宾格 + 后缀-self（单数）/ - selves（复数）＂构成。
　　【家庭成员】
　　人称
　　第一人称
　　第二人称
　　第三人称
　　单数
　　myself
　　yourself
　　himself herself itself
　　复数
　　ourselves
　　yourselves
　　themselves
　　2、反身代词的用法
　　① she called herself xiao zhang. 她自称小张。
　　② we can look after ourselves well. 我们会照顾好自己的。
　　③ the poor boy in the story is myself. 故事里的那个可怜的男孩就是我自己
　　④ they finished the work themselves. 他们独自完成了工作。
　　⑤ did you see mr. wang himself? 你见过 王先生本人吗？
　　【规律总结】
　　反身代词可以作动词或介词的宾语，如例句①②；可以作表语，如例句③；可以作主语或宾语的同位语，用于加强语气，意为＂亲自，本人＂，如例句④⑤。
　　一些常用的固定搭配
　　look after oneself / take care of oneself 照顾自己
　　teach oneself sth. / learn sth. by oneself 自学
　　enjoy oneself 玩得高兴，过得愉快
　　help oneself to sth. 请自用……（随便吃/喝些……）
　　hurt oneself摔伤自己
　　say to oneself 自言自语
　　（二）易错点讲解
　　① 反身代词不能单独做主语，但可以做主语的同位语，起强调作用。例如：
　　我自己能完成作业。（误）myself can finish my homework.
　　（正）i myself can finish my homework.
　　② 反身代词表示＂某人自己＂，不能表示＂某人自己的东西＂，因为它没有所有格的形式。表达＂某人自己的（东西）＂时，须要用one’s own. 例如：
　　我用我自己的蜡笔画画。（误）i’m drawing with myself crayons.
　　（正）i’m drawing with my own crayons.
　　【趁热打铁】用合适的反身代词填空。
　　1. danny, can you do it by __________?
　　2. lily is old enough to look after ________ now.
　　3. please help _________ to the food, jenny and brian.
　　4. they are enjoying ___________ in the park now.

　　keys:1. yourself 2. herself 3. yourselves 4. themselves 5. myself 三、祈使句 （一）祈使句用法讲解 祈使句指的是表示命令、请求、建议或劝告的句子。其主语you常省略，谓语动词用原形，句末用感叹号或句号，读降调。 1. 肯定的祈使句 （1）动词原形+其他  stand up, please. = please stand up. 请起立。 （2）be + n./adj.  be a good boy! 要做一个好孩子! be careful! = look out! = take care! 小心 / 当心！ （3）let + 宾语 + 动词原形 + 其它成分  let me help you. 让我来帮你。 let’s go to school together. 咱们一起上学去吧。 2. 否定的祈使句 (1) don＂t + 动词原形  don＂t stand up. 别站起来。 don＂t be careless. 别粗心。  don＂t let them play with fire. 别让他们玩火。 (2) let型的否定式有两种:＂don＂t + let + 宾语 + 动词原形 + 其它成分＂和＂let + 宾语  + not + 动词原形 + 其它成分＂。  don＂t let him go. / let him not go. 别让他走。  let them not play with fire. 别让他们玩火。 (3) no开头,用来表示禁止性的祈使句。  no smoking! 禁止吸烟!no fishing! 禁止钓鱼! 3. 祈使句的强调形式，通常在肯定祈使句式前加上助动词do。  例如：do shut up! 快住口！ 4. 祈使句的回答 祈使句的动作通常是表示将来发生的动作，所以回答祈使句时，一般用  will或won’t。 在回答具有否定意义的祈使句时，要注意两点： 1) 形式一致(即yes与will保持一致；no与won’t保持一致) 2) 意思相反(即yes是 ＂不＂的意思；no是 ＂是＂的意思)。 在回答时，要注意分析上下文语境中所提供的条件。 如：--- don’t go out, please. it’s raining heavily outside. 请不要出去。外面雨下得很大。  ---- yes, i will. i have to meet my brother at the airport. 不行，我得去机场接我弟弟。  （二）易错点讲解 1、放句首时，要注意don’t后面要用动词原形； 2、当人称后面有标点符号时，要注意是用祈使句还是用三单。 如：lucy, don’t be late again. lucy, a 17-year-old girl, is not late again. 3、祈使句与or的搭配， 如：hands up, or we’ll shoot. 【趁热打铁】 1. _______ late again, bill!  a. don＂t to be b. don＂t be c. not be d. be not 2. _______ cross the road until the traffic lights turn green.  a. not b. won＂t c. doesn＂t d. don＂t 3. kate, _______ your homework here tomorrow.  a. bring b. brings c. to bring d. bringing 4. ________ me the truth, or i＂ll be angry.  a. telling b. to tell c. told d. tell 5 .her doctor said: ＂________ work so hard＂  a stop b don’t c can’t d no  6. sindy, ________ to be here at 8 o’clock  a is sure b is sure that c will be sure d be sure7.________ when you cross the road.  a do care b care c do be careful d to be careful 8. ________ in bed. it’s bad for your eyes.  a not to read b don’t read c don’t to read d not read 9 ______ tell a lie.  a hardly b not c no d never keys: 1-5 bdadb 6-9 dcbd 四、should和had better （一）should用法讲解
　　1. 用于第一人称疑问句，表征询意见。如：should i open the window? 我可以开窗户吗？
　　2. should表义务，可用于各种句式，通常指将来。 如：you should do what your parents tell you.你应该照你父母的话去做事。
　　he should do some work, but he doesn’t want to.他应该做些工作，但是他不想做。

　　八、过去进行时 (一）定义 　　 过去进行时，是表示过去某个具体时刻正在进行的事情或动作。 （二）结构 was/were +doing (现在分词） （三）用法 　　 1、过去进行时表示过去某段时间内持续进行的动作或者事情。常用的时间状语this morning, the whole morning, all day yesterday, from nine to ten last evening, when, while例如： 　　　（1）we were watching tv from seven to nine last night. 　　　　 昨天晚上七点到九点的时候我们在看电视。　　 　　　（2）what was he researching all day last sunday? 　　　　 上周日他一整天都在研究什么？ 2. 过去进行时可以表示在过去某个时间点发生的事情。时间点可以用介词短语、副词或从句来表示。如：　what was she doing at nine o＂clock yesterday? 　　　　昨天晚上九点她在做什么？ (介词短语表示时间点) 　　　　when i saw him he was decorating his room. 　　　　当我看见他的时候他正在装饰房间。 (when从句表示时间点) 　　3. 在复合句中，如果主要动作和背景动作都是延续的或同时发生的，那么主从句的动词都可用过去进行时。例如： 　　　　while he was waiting for the bus, he was reading a newspaper. 　　　　他边等车边看报。 (两个动作都是延续的) 　　　　he was cleaning his car while i was cooking. 　　　　他擦车时我在做饭。(两个动作同时进行) 4、表示在过去即将发生的动作。如：  she asked him whether he was coming back for supper. 5、表示过去的反复性或习惯性的动作，常与副词always,constantly,continually,frequently等连用，常常带有说话人的某种感情色彩。如：his mother was always working like that.他目前总是那样工作。 　　6. 通常不能用于过去进行时的动词主要有：agree, be, believe, belong, care, forget, hate, have(拥有), hear, know, like, love, mean, mind, notice, own, remember, seem, suppose, understand, want, wish等。 （四）过去进行时与一般过去时的区别 （1）过去进行时与一般过去时，两者都表示过去发生的动作,但过去进行时表示在过去某一特定的时间点或时间段正在进行的动作,而一般过去时表示在过去时间完成的动作｡例如: 　　i was typing a letter last night. 昨晚我在打一封信｡(可能没打完) 　　i typed some letters last night. 我昨晚打了一些信｡(已经打完) 　　　　a. 过去进行时却表示动作在持续或未完成，而一般过时往往表示某一动作已经完成。 　　　　i was reading the book at that time. (未读完，＂读＂的片段) 　　　　i read the book yesterday. (已读完，表整个＂读＂) 　　　　b、一般过去时表示只做一次动作，而过去进行时却表示动作反复地进行。 　 　she waved to me. 她朝我挥了挥手。 　　　　it was raining all night.(优先用was raining ,rained 为持续动词，故也可使用) 　　　　he was writing a letter the whole of afternoon. (短暂动词与持续时间连用，表反复，连续发生，不可用一般过去时) 【趁热打铁】 1.  i ______ a meal when you _____ me.
