11、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 many/much 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 famou

14、) can't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mustn' t be请看例句：He can't be a doctor. He must be a dentist.他不会是个医生。他一定是位牙医。She can't be Danish. She must be Norwegian.她不会是丹麦人。她一定是挪威人。He can't be shaving. He must be having a bath.他不可能在剃胡子。他一定是在洗澡。It can't be cheap. It must be expensiv

15、e.它不会便宜。一定价格昂贵。He can't 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, don ' t they陈述部分否定式+疑问部分肯定式可记为 前否后肯They don't work hard, do th

16、ey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。"It ' s new, isn ' t it""是新的，对吗”"Yes, it is." “对，是新的。”"No, it isn't."" 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 isn't new, is it"“不是新的，对吗”“Yes, it is." "不，是新的。” &qu

17、ot;No, it isn't.""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 doesn't 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 doesn't= No, he doesn't （know he

18、r）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.（ 变成般疑问句）3） Mr. Smith must be forty years old.（ 变成否定句）4） He isn't her third husband.（变成反意疑问句）5） Can Liz recognize that woma

20、; ll 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 can' t goanywhere。In the end adv. 最后。等于 at last adv. 最后

21、 =at the end of sth在结尾。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needn' t不必要或 don' t need to。mustn' t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c
