Im going to buy a packet of sweets. a packet of 意为“一包;一袋”。 句中的sweets作名词,意为“糖果”;sweet也可作形容词,意为“甜的”。2. Ive tricked Daisy at last. 句中的trick作动词,意为“戏弄”;trick也可作名词,意为“诡计;花招;骗局”。如:play a trick on sb.。 at last意为“最终”,与in the end和finally意思相同。3. She doesnt even know what electricity is. even在此作副词,表示“甚至;连;即使”,用来强调出乎意料。 even还可以用于比较级前,表示“甚至更;愈加;还”。如:even happier。4. Shell really look foolish. 句中的look为系动词,意为“显得”,后接形容词foolish作表语,说明主语的状态。5. A meter measures the amount you use. amount意为“数量,数额”。an amount of表示“一定量的”,一般修饰不可数名词,修饰可数名词则用a number of。6. Its like water, in a way. in a way意为“在某种程度上;不完全地”,可用partly代替;如表示“就某些方面而言”则用in some ways。7. “Thats not a bad explanation,” said Dad, “although electricity is much more dangerous than water. 句中although是连词,意为“虽然;尽管”,用以引导让步状语从句,可用though来代替,但不能与but同时出现在句子中。although与though的区别:(a) although常用于较正式的场合。(b)even可以与though连用来加强语气,但不可以与although连用。(c)though可用于句末,而although则不可以。句中much是副词,意为“的多”,用来修饰形容词或副词的比较级。类似可修饰比较级的词还有:still, even, far, a little, a lot等。8. You must always be careful with it. be careful with意为“小心对待;谨慎处理”,后常接名词或代词。 Be careful也可以单独使用,意为“小心”,用以提醒他人注意即将来临的危险。 如要接句子,则使用be careful (that) 。9. Can you tell me what it looks like? look like意为“看似样”,look在此处是系动词,like为介词。此外,look like常和what连用表示“看起来怎么样?”10. Dad said, “Nobodys ever seen electricity.” 句中Nobodys是Nobody has的缩写,与后面的seen构成现在完成时。11. Can you think of an example? 句中think of意为“想一想;想出来”。think of也可以表示“考虑;关心”,此时与think about意思相同。如:We are thinking of / about going to France。 另外,What do you think of ?意为“你认为怎么样?”,可用How do you like ?代替。11. Well, it comes into our flat through thin wires, and these are connected to thick wires that are buried under the street. 句中connect是动词,意为“连接;联合”,与join或link意思相近。 一般connect with 指“和连接”,而connect to 指“把连接到”。be connected to是个被动结构,表示“被连接到”的意思。12. Theyre packets that contain electricity. 句中that引导的从句是定语从句,用来修饰之前的名词,此处that还可以用which代替。13. Didnt you know that,Benny? 这是一个反问句。在回答反问句时,与反意疑问句相似。表示知道时,应用Yes, I do.;表示不知道时,应用No, I dont.。情态动词一、主要特征。情态动词后的动词都用原形。构成疑问句,通常把情态动词放在主语前;构成否定句,not放在情态动词之后,其缩写形式为cant, mustnt, neednt, shouldnt等。二、主要用法。1. 用can, could和be able to表示能力。(1) can意为“能够”,否定形式为cannot或cant。 如:He can speak five foreign languages.(2) could是can的过去式。因此,对于过去的时间(如yesterday, last week等),我们不用can或cant,而用could和couldnt。 如:When I was young, I could run very fast.(3) be able to一般可以代替can,也可以表示能力。但can只有一般现在时和一般过去时(could),而be able to则有更多的时态形式。 如:My little brother has been able to write.2. 用must与mustnt, have to与dont have to, neednt表示义务。(1) must用以表示“必须做某事”或“一定要做某事”,具有强制性,表示一定的责任或义务。 如:The windows are very dirty. I must clean them.(2) mustnt是must的否定形式,表示“禁止;绝不允许”,具有强制性。 如:You mustnt play football in the street.(3) must没有过去时,要表达过去的含义,我们可使用had to代替must。 此外,have to侧重这种“义务”或“责任”源于某种客观情况或规定,并非说话者本人能够控制。 如:We missed the last bus, so we had to walk home.(4) dont have to与neednt是“不必”的意思,没有强制性。两者意思相近,但在使用时,前者有人称、时态的变化;后者没有人称变化,而且一般表示现在时间的含义。 如:It has just rained, so he doesnt have to water the garden. You neednt swim in the sea. We have a swimming pool in our hotel.(5) must用于一般疑问句中,其肯定和否定回答应引起注意。 如:Must we go now? 我们一定要走吗? - Yes, we must. 是的,我们一定要走。 - No, we mustnt. 不,我们不可以走。 Must I finish the work this week? 我一定要在这星期完成这项工作吗? - Yes, you must. 是的,你一定要完成。 - No, you neednt. 不,你不一定要完成。 从以上例子中可以看出,用must提问的一般疑问句,否定回答并不一定是mustnt。根据实际含义和情况,我们需要正确选用mustnt或neednt来回答。3. 用can, could与may表示“许可”。(1) 在请求对方的许可,或是准许你做某事时,常用情态动词can, could和may。can最为常用;could较为婉转,更有礼貌;may则比较正式。 如:Can I open the window? - Yes, you can. / No, you cant. Could I borrow a pencil, please? -Yes, certainly. / No, Im afraid not. May I leave early today? - Yes, you may. / No, you may not.(2) 表示给予许可时,通常用can或may,而不用could。 如:Could I borrow a pencil? - Of course you can. May I sit here? - No, you may not.4. 用can, could与would表示“请求”。 当我们需要别人的帮助时,常使用can, could和would这三个情态动词进行提问,但在回答时,could和would则很少使用。 如:Can you open the window? - Yes, I can. Could you pass me the salt, please? - Yes, certainly. Would you help me carry my suitcase? - No, Im afraid not. 常见的肯定回答:Of course I can. / OK. / All right. 常见的否定回答:Im afraid I cant / Of course not.5. 用must和cant表示“猜测”。(1) must表示说话者对某事的发生或情况很有把握,意为“肯定;一定”。 如:Her flat is very near Xujiahui. It must be very noisy.(2) cant表示说话者有相当的把握确定某事不会发生,意为“不可能”。 如:Youve just had lunch. You cant be hungry.6. 用should和ought to表示“义务”和“建议”。(1) should和ought to表示应该做某事,或做某事的动机是正确的。一般可以相互替换。 如:You should / ought to put your rubbish in the bin.(2) ought to的否定形式为ought not to或oughtnt to。构成疑问句,把ought提前至主语前。 如:You ought not to watch TV for too long. Ought we to discuss the work now?(3) should和ought to用在疑问句中时,常用来询问他人的见解或建议。 如:Ought I to finish my homework now? - Yes, you ought to.(4) should和must的区别在于:前者多用于劝说他人的错误行为或给予他人一些建议,不具备强制性;而后者意为“必须”,用于规定或约束他人的行为,具有强制性。 如:You shouldnt be cruel to animals. You mustnt park you car here. Drive it away immediately.(5) should和ought to常与动词think连用。 如:I think Carol should buy some new clothes. Its late. I think I ought to go home now.宾语从句一、概念。 在句中用作宾语的从句叫做宾语从句。宾语从句可分为三类:动词的宾语从句,介词的宾语从句和形容词的宾语从句。二、语序。 宾语从句的构成为“引导词 + 主语 + 谓语 + 其他”,其语序是陈述句语序。三、引导词。1. 如从句是陈述句,用连接词that引导(that在口语或非正式文体中常省略)。如:We know (that) there are two kinds of sports.2. 如从句是特殊提问句,用连接副词why, when, where, how或连接代词who(m), what, which引导。 如:Do you know why I like team sports?I dont know how they got the tickets.3. 如从句是一般疑问句,用连接词whether或if引导(口语中常用if)。if和whether意为“是否”。如;I dont know whether / if they have decided on the date of the meeting.4. 如从句是选择疑问句,多用连接词whether引导,特别是与or not连用时。 如:I dont know whether they will come for our help or not.四、时态。1. 如果主句是现在的时态,从句的时态可根据实际情况而定。 如:I tell him that I moved to Beijing last year. I have heard that he will come back next week.2. 如果主句是过去的某种时态,那么从句的时态也要用过去的某种时态。 如:He said that there were no classes yesterday. Tom told me that he would have a birthday party.3. 如果宾语从句表述的是客观真理、自然现象等时,不管主句是什么时态,从句都要用一般现在时。 如:The teacher said that light travels much faster than sound.五、从句的简化。1. 当主句谓语动词是find, see, watch, hear等感官动词时,从句可简化为“宾语+宾补”结构,宾补为不带to的不定式或v-ing形式。 如:She found that the wallet lay on the ground. - She found the wallet lie on the ground. I heard that the birds were singing in the tree. - I heard the birds singing in the tree.2. 当主语谓语动词是wish, decide, plan, agree, hope等,且主句和从句的主语相同时,从句可简化为不定式结构。 如:She agreed that she could help me with my Maths. - She agreed to help me with my Maths.3. 在连接副词/代词引导的宾语从句中,当从句的主语
