18、nough for you!我认为你看两个小时电视就足够了！此处，two hours of TV虽为复数，但却表达一种整体的观念。英语语法规定，当时间、长度、距离或其他可数名词表示一个完整的整体概念作主语时，其后的谓语动词用其单数形式。Two months is quite a long time.两个月是挺长的一段时间。Thirty students is not a big number for a class. 30人对一个班来说算不上是大数目。3. because Mom will be back from shopping any minute now. 因为妈妈随时都会买完东西回来

40、动词的 can / could, may / might, ought to, must可情态可实义的 need, dare 可情态可助动词的 shall / should, will / would相当于情态动词的 have to, used to情态动词的用法情态动词的语法特征情态动词不能单独做谓语, 除ought和have外, 后面只能接不带to的不定式。 情态动词没有人称, 数的变化, 但有些情态动词, 如can、will也有一般式和过去式的变化。情态动词的“时态”形式并不是时间区别的主要标志, 不少情况下, 情态动词的现在式形式和过去式形式都可用来表示现在时间、过去时间和将来时间。c

41、an 和could：1) can的主要用法是： A. 表示体力或脑力的能力： e.g. The girl can dance very well. B. 表示说话的推测事物的可能性等: e.g. Can the news be true? C. 在口语中, can可以表示请求或允许: e.g. Can I sit here? can表示“能够”时与短语be able to同义，但can只用于一般现在时或过去时，而后者可用于各种时态。另外，can表示个人有某种能力，而be able to表示某人通过努力、克服困难做成某事，相当于succeed in doing sth.；叙述过去事实时，最好用w

42、as / were able to，因为could只表示过去具有某种能力。如：Can you understand the different kinds of English these people are using?Two years later, he was able to speak very good Chinese.2) could的主要用法是： A. could 是can的过去式, 表示与过去有关的 能力和推测: e.g. We all knew that the young man couldnt be a doctor. B. could可以代替can表示请求, 但语气

43、较can 客气、委婉:e.g. Could you lend me your dictionary? Could I use your bike?3) can和could接动词的完成形式，表示可能已经做某事。can用在否定和疑问句中，表示不相信、怀疑等态度。e.g. They cant have gone out because the light is still on.以could或would提问时，不能再以could或would作答，而应该用can或will。如：Could I borrow your dictionary?Yes, of course you can. could与ca

44、n都是情态动词，could是can的过去式。二者都可用于表示请求，但是用法稍有不同。can 表示一般性的请求，语气随便，常用于熟人之间或长辈对晚辈，上级对下级的场合。e.g. Can you tell us your story,Tony？ 托尼，你能给我们讲讲你的故事吗？ could与can的区别 could表示有礼貌的请求，语气委婉，常用于非熟人之间或晚辈对长辈，下级对上级的场合。比如： Could you tell us if it snows in winter in Australia? Sure. 请告诉我们，澳大利亚冬天下雪吗? 当然可以。 注意：1. 提出委婉的请求在回答中不可

45、用could。 A: Could I have the television on? B: Yes, you can. / No, you cant.2. 在否定、疑问句中表示推测或怀疑用couldnt。 He couldnt be a bad man. 他不大可能是坏人。may和might表示允许或请求；表示没有把握的推测；may放在句首，表示祝愿。 May God bless you! He might be at home.注意: might 表示推测时，不表示时态，只是可能 性比may小。have to和must1. 两词都是“必须”的意思，have to 表示客观的需要，must 表

46、示说话人主观上的看法，即主观的必要。My brother was very ill, so I had to call the doctor in the middle of the night.我弟弟病得很厉害，我只得半夜里把医生请来。(客观需做此事)He said that they must work hard. 他说他们必须努力工作。(主观上要做这件事)2. have to 有人称、数、时态的变化，而must只有一种形式。但must 可用于间接引语中表示过去的必要或义务。He had to look after his sister yesterday.3. 在否定结构中: dont

47、have to 表示 “不必”，mustnt 表示“禁止”。You dont have to tell him about it. 你不一定要把此事告诉他。You mustnt tell him about it.你一定不要把这件事告诉他。Write R for requests and P for permissions. Then match each one with the correct response. _ Could I hang out with my friends after the movie?2. _ Could you please pass me the salt

54、n Crusoe？ Mrs Zhao Sure, its very interesting, but you can only _ it for two weeks A. borrow; lend B. lend; borrow C. borrow; keep D. lend; keep中考链接C【解析】 句意：“我可以借鲁宾逊漂流记吗?”“当然，它很有趣，但是你只能借两个星期。”考查动词辨析。borrow借入，短暂性动词；lend借出，短暂性动词；keep保持，这里强调保管，延续性动词。Can I borrow Robinson Crusoe？强调借入，所以前句用borrow；后句句中for

55、 two weeks是一段持续的时间，第二个空需用延续性动词keep。这个暑假你与父母要去法国度假， 你的宠物小猫Mimi需要请Jimmy帮忙照顾。请用下面的提示词给Jimmy写份留言。take care of, take for a walk, feed and give some water, play with him, cleanDear Jimmy, _.
