LeadingRead the passage again and fill in the blanksCreativity is a matter of habits. In order to be more creative, we should think about how we think and practising good thinking strategies. To “ think outside the box” is a conscious effort to break away from old thought patterns in order to explore new possibilities. A change in perception - to take another look at the problem-may lead to good solutions and new ideas. Great thinkers are aware of “making connections” and try to bine new and old ideas in as many different ways as possible. By paring and connecting ideas and objects in new ways, creative thinkers are able to think of new applications and solutions. Good ideas are no accident. They are the result of a long progress of trial and errors. If we want to develop our creativity, we can try using these thinking strategies to find new ways to improve our life.设计意图: Remember and consolidate some language points about this unit. 师生互动: Let the students do them and check answersStep2. Grammar 关系代词与关系副词辨析定语从句的考查主要集中在引导词的确定上。准确判断引导词在定语从句中所作的成分是选择引导词的关键。关系代词that, which, who, whom在从句中作主语和宾语，作宾语时可省略；关系副词where, when, why在从句中作状语；whose在定语从句中作定语，起限定作用。下面，请大家用适当的引导词填空，完成下列句子。1.Ill never forget the days _ I worked together with you on the farm.2.Ill never forget the days _ I spent together with you on the farm.3.Whats the reason _ he gave for his failure in the last exam?4.Do you know the reason _ he failed in the last exam?5.Do you know the woman _ son went to college last year?6.The house, _ roof was destroyed in the terrible fire, has been repaired.7.Beijing, _ is the capital of China, is the host of the xx Olympic Games.8.Beijing, _ he studied two years ago, is the host of the xx Olympic Games.Keys: 1. when 2. that / which / 不填 3. that / which /不填 4. why / that /不填 5. whose 6. whose 7. which 8. where“介词+关系代词”引导定语从句关系代词在定语从句中作介词宾语时，从句常由“介词+关系代词”引导。介词后的关系代词主要是which和whom，间或是whose，但不能是that。有时，介词前可有数词、代词、形容词比较级或最高级修饰。下面，请大家根据汉语提示，用定语从句完成下列句子。1.In the dark street, there wasnt a single person _ (她可以求助).2.The boss, _ (我妈妈在他的公司工作), is a warm-hearted young man. 3.We arrived at a farmers house, _ (房子后面有一块麦田).4.The factory produces half a million pairs of shoes every year, _ (其中80%销往国外). 5.The old man has three children, _ (其中两个是大学老师).6.There are seven continents in the world, _ (其中最大的是亚洲).Keys: 1.to whom she could turn for help 2.in whose pany my mother works3.at the back of which was a wheat field 4.80% of which are sold abroad5.two of whom are college teachers 6.the largest of which is Asia 限制性和非限制性定语从句限制性定语从句是先行词不可缺少的修饰部分，去掉它主句意思往往不明确；非限制性定语从句用来对主句内容作补充、解释或附加说明，和主句的关系不十分密切，没有它，主句意思仍然完整。非限制性定语从句和主句之间往往用逗号分开。注意：关系代词that不能引导非限制性定语从句；在非限制性定语从句中即使关系代词which, whom在从句中作宾语，也不能省略。下面，请大家把下列句子译成汉语，并分析、比较其意义的不同。1.My brother who is an engineer is 25 years old.2.My brother, who is an engineer, is 25 years old.3.Mr. Smith, who used to be my English teacher, will retire next month. 4.The teacher who used to teach me English will retire next month. 定语从句中的主谓一致关系代词作主语时，定语从句中谓语动词要与先行词在人称和数上保持一致。注意：当先行词是one of .时，定语从句中谓语动词用复数；当先行词是the one of .或the only one of .时，从句中谓语动词用单数。下面，请大家用括号内所给词的适当形式填空。1.Those who _ (want) to go to the film tonight please sign here.2.He who _ (not reach) the Great Wall is not a true man. 3.She is the only one of the girls who _ (have) been to Beijing. 4.She is one of us who _ (be) praised at the meeting yesterday.5.I, who _ (be) your friend, will always be ready to lend you a hand. 关系代词as和 which 引导的定语从句关系代词as和 which都可以指代整个主句或主句的一部分，引导非限制性定语从句，并且在定语从句中作主语或宾语。其中，as引导的非限制性定语从句位置较灵活，可以位于主句前、中或后，而which引导的定语从句只能放在主句后。下面，请大家根据括号内的汉语提示，用定语从句完成下列句子。1.The result of the experiment was very good, _ (这大大出乎我们的意料).2._ (众所周知), China has the largest population in the world.3.The boy was late for class again, _ (这使得老师非常生气).4.He can write a letter in English, _ (我不行).定语从句中关于that的使用1.当先行词为anything，everything，nothing等不定代词时，只能使用“that”。Is there anything I can do for you? 2.当先行词为all，any，much，many词时，只能使用“that”。Tom told her mother all had happened.3.当先行词是形容词最高级或被形容词最高级修饰时，只能使用“that”。 This is the most wonderful time I have ever had. 4.当先行词是序数词修饰时，只能使用“that”。 He was the first person passed the exam. 5.先行词被the only，the very，the same，the last修饰时，只能使用“that”。例：1.This will be the last chance he can get. 2.He is the only person can help you out.人。6.先行词里同时含有人或物时，只能使用“that”。 They talked of things and persons they remembered in the school. 7.当主句是以who，which 开头的特殊疑问句或先行词是who时，只能使用“that”。 Which is the book he bought from the library yesterday? 设计意图:Observe the different forms and distinguish the differences between them师生互动: Ss and Teacher will finish them together三、目标检测通过本节课的学习你能完成教材课后练习P132 第3题的练习吗？配餐作业 A组题1.
