Im afraid you wont have time to _ before the party. A. get changed B. get change C. get changing D. get to change,2019/7/31,30, Be careful when you cross this very busy street, if not, you may _ run over by a car. A. have B. get C. become D. turn As we joined the big crowd I got _ from my friends. A. separated B. spared C. lost D. missed,分析：例中考查的是“ get 过去分词”构成的系表结构。例 get changed 意为“换衣服”，例 get run over 意为“碾过，压过”，例 get separated 意思是“冲散，分离”，所以正确答案分别是 A 、 B 、 B 。,2019/7/31,31,2. 对 go 的考查 系动词 go 的意义是“变成，成为”，后多跟形容词，如 go bad, go mad, go wrong, go hungry, go sour 等。例如： On hearing the news of the accident in coal mine, she _ pale. A. got B. changed C. went D. appeared,分析：该题考查的是“ go+adj. ”系表结构。 got 和 changed 不能与 pale 搭配起来表达这一状态的变化，而 appeared 是表示状态存在的系动词。所以正确答案是 C 。,2019/7/31,32,3. 对 fall 的考查 系动词 fall 表示“（不知不觉地或突然地）进入状态”，后常跟形容词、副词或介词短语等，如： fall ill （生病）， fall apart （散开）， fall asleep, fall into a deep sleep （睡熟）。例如： As she _ the newspaper, Granny _ asleep. A.read; was falling B. was reading; fell C. was reading; was falling D. read; fell,分析：该题第二空考查的是系动词“ fall+adj. ”结构， fall asleep 是短暂性动词短语，不能用于进行时态，故正确答案是 B 。句意是“她读报时，奶奶睡着了。”,2019/7/31,33,三 . 对表示状态存在的系动词的考查 常见的有 be, seem, appear, look, feel, smell, sound, keep, taste, remain, prove, stay, lie （处于某种状态）， stand （处于某种状态）等。 1. 对 remain 的考查 系动词 remain 的意思是“保持，继续，依然不变”，后常接名词、形容词、副词、介词短语、不定式等。 Having a trip abroad is certainly good for the old couple, but it remains _ whether they will enjoy it. A. to see B. to be seen C.seeing D. seen,2019/7/31,34, Although he has taken a lot of medicine, his health _ poor. A. proves B. remains C. maintains D. continues,分析：例中的 remain 是个半系动词，“有待被看，证实”，所以应用不定式的被动式，故答案是 B 。例中 remain poor 意为“仍然很差”， maintain 意为“维持，保持，继续”，不与形容词 poor 连用，所以正确答案是 B 。,2019/7/31,35,2. 对 stay 的考查 stay 意为“保持原状，维持”，后面可以接形容词、副词、介词短语、名词等。 The weather has stayed warm all week. Why dont you put the meat in the fridge? It will _ fresh for several days. A. be stayed B. stay C. be staying D. have stayed,分析：该题考查的是系动词 stay 后接形容词（ fresh ）的系表结构，它表示一种存在的状态，主动形式表示被动意义，这种结构一般不能用于进行时态，所以正确答案是 B 。,2019/7/31,36,3. 对 appear 的考查 appear 的含义是“似乎，好像，看来（如关于某人的性格、感情或意图）”，此时不用进行式，后接形容词、名词、动词不定式等。 She appeared rather upset about something. 看来有些什么事使她心烦。 Do let your mother know all the truth. She appears _ everything. （上海 2001 ） A. to tell B. to be told C. to be telling D. to have been told,2019/7/31,37,分析：句意是“一定要把一切真相告诉你妈妈。她看上去已经知道一切事情。”句中 tell 后面没有宾语，故用不定式的被动式，又因为“知道一切”发生在“告诉真相”之前，要用完成式。所以正确答案是 D 。,4. 对 feel 的考查 feel 的意思是“感觉是，似乎”，后常接形容词、副词、介词短语等。 I love to go to the seaside in summer. It _ good to lie in the sun or swim in the cool sea. A. does B. feels C. gets D. makes,2019/7/31,38, - Do you like the material? - Yes, it _ very soft. A.is feeling B.felt C.feels D.is felt,分析：这两道考题考查的是“ fell+adj. ”的系表结构。例中 feel good 意为“感觉舒服”；例 feel soft 意为“摸上去软和”，此时，主动结构表示被动的含义。所以正确答案分别是 B 和 C 。,2019/7/31,39,5. 对系动词 look 的考查 look 有“看来，显得”等意，后面常接形容词、介词短语、不定式短语、从句等。 The plan looks good on paper, but will it work? 这个计划从表面上看来不错，但能行得通吗？ -You dont look very _. Are you ill? - No,Im just a bit tired. A. good B. well C. strong D. healthy,分析：尽管提供的四个备选项都是形容词，但 look well 的意思是“看上去气色好”，符合对话的语境，故正确答案是 B 。,2019/7/31,40,6. 对 sound 的考查 sound 有“听起来，令人觉得，似乎”等含义，后面可以接形容词、名词短语、介词短语、不定式等。 She sounds to be a very strange woman. 听起来她似乎是一个非常古怪的女人。 What he said sounds _ . A. nicely B. pleasantly C. friendly D. wonderfully,分析：四个选项中只有 friendly 是形容词，可以和 sound 连用构成系表结构，其他三项都是副词，只能作状语不能作表语，所以正确答案是 C 。,2019/7/31,41,7. 对 taste 的考查 taste 在使用时不用进行时态，含义是“尝起来，有某种特殊的味道”，一般接形容词构成系表结构。 These oranges taste nice. 这些橙子味道很好。 These oranges taste _ . A.good B. well C. to be good D. to be well,分析： taste 是系动词，所以要用形容词 good 作其表语。 well 作形容词时，意思是“健康的”，只能形容人，不能形容物。故正确答案是 A 。,2019/7/31,42,8. 对 smell 的考查 smell 经常与形容词连用，意思是“闻起来，有气味，发出的气味”。 This book smells old. 这本书有一股霉味。 We dont care if a hunting dog smells _, but we really dont want him to smell _ . A. well; well B. bad; bad C. well; badly D. badly; bad,分析：第一空前的 smell 是不及物动词，意为“嗅，闻，有嗅觉”，副词 badly 修饰 smells ；而第二空前的 smell 是系动词，与形容词 bad 构成系表结构。 答案为D,2019/7/31,43,基本句型 二： （主谓） 主语：可以作主语的成分有名词（如boy），主格代词（如you），动词不定式，动名词等。主语一般在句首。注意名词单数形式常和冠词不分家！ 谓语：谓语由动词构成，是英语时态、语态变化的主角，一般在主语之后。不及物动词（vi.）没有宾语，形成主谓结构，如：We come. 此句型的句子有一个共同特点，即句子的谓语动词都能表达完整的意思。这类动词叫做不及物动词，后面可以跟副词、介词短语、状语从句等。, （不及物动词） 1.

She made a beautiful dress for me.,2019/7/31,52,用to侧重指动作的方向，表示朝着，向着，对着某人。 用for 侧重指动作的受益者，表示为了某人，替某人。 常跟双宾语的动词有：（需借助to的）bring, give, lend, hand, offer, pass, pay, promise, return, send, show, teach, tell, write, ask等； （需借助for 的） buy, call, cook, choose, draw, find, get, make, order, sing, save, spare等。,2019/7/31,53,巩固练习： 1Johnson 先生去年教我们德语。 2奶奶昨晚给我们讲了一个有趣的故事。 3请把那本字典递给我好吗？ 4他把车票给列车员看。,Mr Johnson taught us German last year.,Grandma told me an interesting story last night.,Would you please pass me the dictionary?,He showed the ticket to the conductor.,2019/7/31,54,巩固练习： 5我替你叫辆出租汽车好吗？ 6新式机器将会为你节省许多劳动。 7他用他的第一个月工资给他妈妈买了一件毛衣。,Shall I call you a taxi?,The new machine will save you a lot of labour.,7.He bought a new coat for his mother with his first months salary.,2019/7/31,55,说明: 此结构由“主语+及物的谓语动词+宾语+宾语补足语”构成。宾语与宾语补足语之间有逻辑上的主谓关系或主表关系，若无宾语补足语，则句意不够完整。 The sun keeps us warm. I heard him singing. You must get your hair cut.,基本句型 五： （主谓宾宾补）,2019/7/31,56, （及物） （宾语） （宾补） 名词/代词宾格 + 名词 The war| made| him |a soldier./战争使他成为一名战士. 名词/代词宾格 + 形容词 New methods |make |the job| easy./新方法使这项工作变得轻松. 名词/代词宾格 + 介词短语 I |often find| him |at work./我经常发现他在工作. 名词/代词宾格 + 动词不定式 The teacher| ask |the students |to close the windows./老师让学生们关上窗户. 名词/代词宾格 + 分词 I |saw |a cat |running across the road./我看见一只猫跑过了马路.,2019/7/31,57,用 it 做形式宾语，而将真正的宾语放到宾语补足语的后面，以使句子结构平衡，是英语常用的句型结构方式。即：主语+谓语+it+宾补+真正宾语。如： I found it very pleasant to be with your family.,2019/7/31,58,巩固练习： 1我们叫她Alice. 2我们大家都认为他是诚实的。 3他们把小偷释放了。 4我要你把真相告诉我。 5 .卫兵命令我们立即离开。 6. 每天早晨我们都听到他大声朗读英语。 7他每个月理一次发 8我们不会让她在晚上外出的。,We call her Alice.,All of us considered him honest.,They have set the thief free.,I want you to tell me the truth.,The guards ordered us to leave at once.,Every morning we hear him read English aloud.,He has his hair cut every month.,We wont let her go out at night.,2019/7/31,59,9那可怕的声音把孩子们吓坏了 10她正在听人家讲故事。 11我从来没看见这个字这样用过。 12他感到很难跟你交谈。 13我认为有可能用另一种方法解题。 14学校定了一条规则，开始上课时学生要起立。,The terrible sound made the children frightened.,She is listening to someone telling stories.,I have never seen the word used that way before.,He felt it very difficult to talk with you.,I consider it possible to work out the problem in another way.,The school made it a rule that the students should stand up when class begins.,2019/7/31,60,英语基本句型6 There be 句型 说明： 此句型是由“there+be+主语+状语”构成，用以表达存在关系可以称“有”。 它其实是倒装的一种情况，主语位于谓语动词 be 之后，there 仅为引导词，并无实际语意。 此句型有时不用be动词，而用 live, stand, come, go, lie, remain, exist, arrive等。如： There stands a hill in the middle of the park. Once upon a time there lived an old king in the town.,2019/7/31,61,Be 与其后的主语在人称和数量上一致，有时态和情态变化。如： 现在有 there is/are 过去有 there was/were 将来有 there will be；there is /are going to be. 现在已经有 there has/have been 可能有 there might be. 肯定有 there must be /there must have been. 过去曾经有 there used to be 似乎有 there seems/seem/seemed to be 碰巧有 there happen/happens/happened to be ,2019/7/31,62,巩固练习： 1这个村子过去只有一口井。 2客人当中有两名美国人和两名法国人。 3天气预报说下午有大风。 4灯亮着，办公室里肯定有人。 5战前这儿一直有家电影院的.,There was only a well in the village.,Among the guests there were two Americans and two Frenchmen.,The weatherman says therell be a strong wind in the afternoon.,The light is on.
