Can you. 表示请求你能借我10美元吗？Can you lend me 10 dollars?Can I . 表示提议要不要我帮你煮点咖啡。Can I make you some coffee? 2. I think I can, Kate. It must be Karen Marsh, the actress. I think I can. 否定句：I dont think I can. must be 一定是 （表示一种极为肯定的猜测）e.g.:己经10点了，我妈妈一定会生气的。Its already ten oclock. My mother must be angry. e.g.:我们认为老师一定是在开玩笑。We thought the teacher must be joking3. I thought so. Whos that beside her? 我也这么认为/我原以为也是这样/果然如此beside / next to / near4. Conrad Reeves, the actor? It cant be. Let me have another look. I think youre right!

That was a long time ago, wasnt it? 反义疑问句, 前面肯定，后面否定/ 前面否定，后面肯定 时态人称不变否定疑问句和反义疑问句的回答方式把我一点：就着事实回答即可。看后半部分。在英语中，Yes是和肯定搭配的，No是和否定搭配的，这与汉语是不同的。8. Not that long ago! Im not more than twenty-nine myself. not more than 不多于，只是客观陈述数量 There are not more than ten books in my bag.no more than = only仅仅，只有，强调少 He is no more than a worker.not less than 不少于 There are not less than ten books in my bag.no less than 不亚于, 竟达相当于“ as manymuch as .”，强调多。 He paid no less than $10，000 for it.根据括号里的提示的适当形式完成句子。1) She must be Karen Marsh，the famous_.(actor )2) She cant be English.

Grammar1. 表示猜测和推断的情态动词must和cant must, cant表猜测表示对现在和将来的事做推断和猜测，与系动词be连用 must，cant 都可以表示猜测must 表示肯定的猜测，用于肯定句，表示“一定是.”，非常肯定的语气.(注意：表猜测时，must不能用语疑问句） cant 表示否定的猜测，用于否定句，或否定的回答，表示“不可能是.” 而不是mustnt be请看例句：He cant be a doctor. He must be a dentist.他不会是个医生。他一定是位牙医。She cant be Danish. She must be Norwegian.她不会是丹麦人。她一定是挪威人。He cant be shaving. He must be having a bath.他不可能在剃胡子。他一定是在洗澡。It cant be cheap. It must be expensive.它不会便宜。一定价格昂贵。He cant be ill. He must be tired.他不可能生病了。他肯定是累了。2. 反义疑问句 反义疑问句，即附加疑问句。它表示提问人的看法,没有把握,需要对方证实。 反义疑问句由两部分组成：前一部分是一个陈述句，后一部分是一个简短的疑问句。 （注意：后一部分的简短疑问句，由“助动词+主语”构成。两部分的人称时态应保持一致。） 陈述部分肯定式+疑问部分否定式 可记为 前肯后否 They work hard, dont they? 陈述部分否定式+疑问部分肯定式 可记为 前否后肯 They dont work hard, do they? 反义疑问句的回答： 1. 当陈述部分为肯定式，反意疑问句为否定式时，回答只需照情况即可。 "Its new, isnt it?" “是新的，对吗？” "Yes, it is." “对，是新的。”"No, it isnt." "不，不是新的。” 2. 当陈述部分为否定式，反意疑问句为肯定式时，其回答往往与汉语不一致，需特别引起注意： "It isnt new, is it?" “不是新的，对吗？” “Yes, it is." “不，是新的。” "No, it isnt." “是的，不是新的。” （tips:回答否定式的反意疑问句，yes跟肯定，No接否定的规则还是不变的。翻译回答部分的时候，只需要把翻译疑问句中省略的部分重现在回答中，就可以正确地翻译出来。） 如：He doesnt know her, does he? 他不认识她，是吗？ Yes，he does.=Yes, he does (know her) 在翻译的时候，不用去管yes，只需要翻译后部分，他认识她。所以整个回答就应该是，“不，他认识她。” No, he doesnt= No, he doesnt (know her) 翻译时，先后半部分，他不认识她。之后再结合句子来把yes跟no的具体含义，分析清楚。 IV. Homework.按要求改写句子1) Conrad Reeves is sitting beside her.( 针对划线部分提问）_2) Karen was a famous actress when Liz was still at school.(变成一般疑问句）_3) Mr. Smith must be forty years old.（变成否定句）_4) He isnt her third husband.( 变成反意疑问句）_5) Can Liz recognize that woman？.( 变成肯定句）_根据汉语补全句子1) 他一定知道点什么。He_ something about it.2) 萨利不可能很大年纪。她大约25岁，不是吗？Sally_ _ _.

Have something _ _.下列表示建议的情态动词：必须must、have to应该had better、ought to、should可以can、would、may、wouldIll certainly be more careful. 我以后一定会多加注意。这里面助动词是will，应该放在前面。It takes a long time. take用于花费时间。It takes sb. sometime to do sth 做某事需要花费某人多长时间It took me a week to finish this work. 我完成这项工作花了一周的时间。We might not go anywhere. 我们可能哪也不去，而不是我们不可能去那。 We cant go anywhere。In the end adv.最后。等于at last adv.最后 at the end of sth 在结尾。l Expressions1. must和have to的用法两者都表示必要性，两者的主要区别在于：1. must表示主观意愿，而have to表示客观事实。2. must 只用于现在时，而过去时用had to，将来时用will have to。3. must 不用于否定句，否定句用neednt 不必要或dont need to。mustnt的意思是不允许，禁止。2. 情态动词表示推测：情态动词表示推测的有：must一定、could很有可能、may可能、might有一些可能。它们的用法是：1. 它们表示推测只能用于肯定句之中，而疑问句用can，否定句用cant不可能。Can the he stay at home at the moment? 现在他能在家么？He must be staying at home. 他一定在家。He cant be staying at home. 他不可能在家。2. 情态动词用原形，表示对现在或将来的情况时行推测。He must be a teacher. 他可能是一名老师。（系表）We may travel by sea next month. 下个月，我们可能乘船旅行。3. 情态动词用be doing，表示对现在的情况进行推测。He must be having a lot of money. 他一定有很多钱。Jim may be playing the basketball. 吉姆可能正在打篮球。4. 情态动词用have done，表示对过去的情况进行推测。It must have rained yesterday. 昨天一定下雨了。I cant have been late yesterday. 我昨天不可能迟到。She could have phoned you last night. 她昨晚应该给你打电话了。He must have stayed at home when we arrived. 当我们到达的时候，他一定在家。5. 情态动词用have been doing，表示对过去正在进行的动作或过去一直进行的动作进行推测。She may have been doing his homework last night. 昨天晚上，他可能一直在写作业。
