35、ess.  费事是我把他的地址丢了。 The reason was that he was late for school.(2) 附属连词whether, as, as if。如：1. He looked just as he had looked ten years before.  他看起来还与十年前一样。2. The question is whether they will be able to help us. 问题是他们是否能帮我们。注：附属连词if一般不用来引导表语从句，但as if却可引导表语从句，如：All this was over

36、 twenty years ago, but its as if it was only yesterday.这都是20多年前的事了，但宛如昨天一样。The key is whether we can solve the problem. 看起来好似要下雨。It looked as if it was going to rain.注：能跟表语从句的谓语动词一般为系动词be, seem, look，sound等。如：He looked just as he had looked ten years before. 他看起来还与十年前一样。 造句：听起来好似有人在敲门。It sounds as i

37、f someone is knocking at the door. (3) 连接代词who, whom, whose, what, which, whoever, whatever, whichever 在表语从句中做主语、宾语等。如：The problem is who we can get to replace her. 问题是我们能找到谁去交换她呢。That was what she did this morning on reaching the attic. 那就是她今晨上了阁楼干的。 造句： 问题是我们能找到谁去交换她呢。 The problem is who we can ge

38、t to replace her.我想问的是谁分开了。 My question is who left. (4) 连接副词 where, when, how, why。What I wonder is when he left. 我想知道他是何时分开的。This is where they once lived. 这就是他们曾经住过的地方。造句：这就是他为何没到这儿来的原因。 要练说，得练听。听是说的前提，听得准确，才有条件正确模拟，才能不断地掌握高一级程度的语言。我在教学中，注意听说结合，训练幼儿听的才能，课堂上，我特别重视老师的语言，我对幼儿说话，注意声音清楚，上下起伏，抑扬有致，富有吸引

39、力，这样能引起幼儿的注意。当我发现有的幼儿不专心听别人发言时，就随时表扬那些静听的幼儿，或是让他重复别人说过的内容，抓住教育时机，要求他们专心听，用心记。平时我还通过各种兴趣活动，培养幼儿边听边记，边听边想，边听边说的才能，如听词对词，听词句说意思，听句子辩正误，听故事讲述故事，听谜语猜谜底，听智力故事，动脑筋，出主意，听儿歌上句，接儿歌下句等，这样幼儿学得生动活泼，轻松愉快，既训练了听的才能，强化了记忆，又开展了思维，为说打下了根底。That is why he didn't come here. 造句：问题是他是如何做此事的。 The question is how he did

40、it.  (5) 连词because可引导表语从句。如：I think it is because you are doing too much. 我想这是因为你做得太多。造句：这是仅仅因为他不认识她。 It's just because he doesn't know her. That's because he didn't understand me. 那是因为他没有理解我。That's because.强调原因 That's why he got angry with me. 那正是他对我生气的原因。 That'

41、;s why.强调结果 (6) 在一些表示“建议、劝说、命令的名词后面的表语从句中，谓语动词用虚拟语气。should+动词原形表示，should可省略。如：My suggestion is that we should start early tomorrow. 我的建议是我们明天一早就出发。同位语从句同位语从句说明其前面的名词的详细内容。1、 同位语从句通常由that引导，可用于同位语从句的名词有advice、demand、doubt、fact、hope、idea、information、message、news、order、problem、promise、question、request、

42、suggestion、truth、wish、word、rumor等抽象名词。例如：The news that we won the game is exciting. 我们赢得这场比赛的消息令人冲动。I have no idea when he will come back home. 我不知道他什么时候回来。The thought came to him that Mary had probably fallen ill. 他想到可能玛丽生病了。2、如同位语从句意义不完好，需增加"是否"的含义，应用whether引导同位语从句。例：We'll discuss th

43、e problem whether the sports meeting will be held on time.析：the sports meeting will be held on time意义不完好，应加"是否"的含义才能表达the problem的全部内容，因此应用whether引导同位语从句。3、如同位语从句意义不完好，需增加"什么时候"、"什么地点"、"什么方式"等含义，应用when, where, how等词引导同位语从句。Eg: 1：I have no idea when he will be

44、back. 2：I have no impression how he went home, perhaps by bike. 4、当主句的谓语较短，而同位语从句较长时，同位语从句常后置。eg：The thought came to him that maybe the enemy had fled the city. 同位语从句与定语从句的区别：1、 定语从句中的that既代替先行词，同时以在从句中作某个成分主语或宾语，而同位语从句中的 that是连词，只起连接主句与从句的作用，不充当句中任何成分。2、 定语从句是形容词性的，其功能是修饰先行词，对先行词加以限定，描绘定的性质或特征；同位 语

45、从句是名词性的，其功能是对名词进展补充说明。例如：1 The news that he told me is that Tom would go abroad next year.他告诉我的消息是汤姆明年将出国。2The news that Tom would go abroad is told by him.汤姆将出国的消息是他讲的。I had no idea that you were herethat引导同位语从句，不能省略Have you got the ideathatthis book gives you of life in ancient Greece？that引导定语从句，作

46、宾语，可以省略四、例题精析【例题1】 【题干】To some people，happiness _family and friends. 对于有些人来说，幸福就是被朋友和家人包围着。 【答案】is being surrounded by 【解析】此题考察词汇surround的使用。【例题2】 【题干】The National Stadium which looks very magnificent_258,000 square metres in area.Ais measuring Bis measuredCmeasured Dmeasures【答案】：D【解析】：句意：看起来非常辉煌的国家

47、体育馆面积为258 000平方米。measure在此处为不及物动词，指尺寸、长短、数量等。用作此含义时，不能用于进展时，也不能用于被动语态。【例题3】 【题干】These soldiers defend the _ area of China's North all year round.Aborder BharborCglobe Dscenery【答案】：A【解析】：句意：这些士兵整年都在保卫中国北疆国门。border国界，国门；harbor港口；globe地球；scenery风光。 五、课堂运用【根底】1、More consumers are waiting for the fur

49、h 【答案】A 【解析】词组have a gift for的含义是“在有天赋。present作“礼物讲与gift是同义词，但它没有“天赋的含义。3、It was so noisy outside that he couldn't _ down to reading.Asettle Bput Csit Dlie【答案】A【解析】句意：外边太吵了，他静不下心来读书。settle down to“定下心来做；put down“记下，放下；sit down“坐下。【稳固】This jacket looks beautiful on you.
