Unit 4 Astronomy: the science of the starsLearning about language-Grammar :The Subject ClauseTeaching plan & design临泉田家炳实验中学 周大磊Teaching analysis：This is the fourth teaching period of this unit. This teaching period mainly deals with the following: 1. Reviewing noun clauses as the object and as the predicative; 2. Learning the new grammar items: noun clauses as the subject. Students often feel noun clauses abstract and difficult to learn, so it is necessary to make the lesson interesting and lively, and connect it with their daily life in order to let it easy to accept and understand. Firstly, the teacher can show some pictures about the topic of mother and ask them several questions .From these questions we know that noun clauses are used as the subject, . Secondly, compare and discover the uses of each noun clause by giving a lot of example sentences. Thirdly, do the exercises in Discovering useful structures on Page 29 and more exercises for students to master the related noun clauses. Finally, summarize the use of noun clauses as the subject and let students make it clear how each noun clause is being used in the situations.At the end of the class, ask students to do the exercises in Using structures on Page 64 (the workbook exercises) and more additional exercises for consolidation.Teaching important points：Get students to understand and use noun clauses as the subject.Teaching difficult points：Enable students to learn how to use noun clauses as the subject correctly.Teaching goals：Knowledge aims：1.

Teaching procedures Step 1 Lead-in 5Good afternoon,everyoneThis class，lets deal with the grammar part：The Subject Clause.

What I want to apologize is that-3. It is necessary that -(should)-4. It is a pity that- Ask students to complete the sentence on their exercise. Ask them to discuss with their partners in group and then choose one sentence that they all think is the best.If students have some difficulty, give them a hand. Questions ：(what are the connectors (连接词)? How do we use them correctly ?)Suggested answers: 1 What I want to say is that I love my mother very much 2 What I want to apologize is that I brought a lot of trouble to my mother when I was a little child. 3 It is necessary that we should trust and respect our mothers . 4 It is a pity that I forget my mothers birthday date . Step 2 Grammar learning 35 Summing up: noun clauses as the subject. 主语从句作主语用的名词性从句, 因其在复合句中作主语, 又称主语从句。（1）连接词:1)连词 that, whether等。that 引导主语从句只起引导作用, 本身无实际意义, 在主语从句中不充当任何成分, 但不能省略。That she was chosen made us very happy由whether引导的主语从句不担任句子成分，用在疑问意义的句子中，意为“是否”Whether we will hold a party in the open air tomorrow depends on the whether2) 连接代词 who, what, which, whoever, whatever, whichever等。Who he is is not important. What he told me was true.3) 连接副词 when, where, how, why等。When we will start off is an important question Why John did it this way was unexpected.（2）位置主语从句可以前置, 也可以后置。用it作形式主语, 而把主语从句放在句末, 常用下面几种句型:1) It + be+形容词（obvious、true、natural，etc）+ that-clause It is certain that she will do well in her exam.2) It +be+名词词组（no wonder、an honor，etc）+ that-clause Its no surprise that our team should have won the game.3) It+be+过去分词（said、reported、proved，etc） + that-clause It has been proved that what you said is right4) It+不及物动词（happen、seem、appear,etc） + that-clause It seems that he has lost something主语从句的注意事项1.从句的语序：在任何情况下，主语从句都用陈述语序。Whichever of you gets here first will get the prize. How he succeeded is still a puzzle.2.主谓一致1）从句作主语，主句的谓语一般用单数形式；但what和who引导主语从句时，有时主句谓语的数应与主句中作表语的名词保持一致。 What they need are books. What they need is love2)如果由and连接两个或两个以上的主语从句时，谓语动词用复数；由两个或多个连接词引导一个主语从句时，谓语动词用单数。When they will start and where they will go have not been decided yet.When and where the meeting will be held has not been decided.3)whether引导的主语从句，如果用了形式主语it,引导词whether可以换成if。如果whether从句在句首或后面直接跟有or not时，不能用if 替换。Whether they will sell the house is not yet decided.(此时whether与if不可互换)=It is not decided yet whether/if they will sell the house.(此时whether与if可互换)Step 3 Grammar practice 5 Ask students to finish the following exercises within 5 minutes.
