第二部分   教学流程
step 1  lead-in 
t: hello, everyone! nice to see you again. today we are going to learn the grammar part together.
as we know, millie is also thinking about buying a robot. but she hasn’t decided yet. she’s asking daniel a few questions. look at the questions. 
l  can the robot cook?
l  will the robot bring any bad changes to your life?
l  can you stay in bed for a bit longer?
l  do robots sometimes go wrong?
l  can you return it to the shop?
t: can you make sentences with “if” or “whether”? for example, no. 1, “can the robot cook?”
        millie asked daniel if/whether the robot could cook.
        now, it’s your time to have a try.
        millie asked daniel if/whether the robot would bring any bad changes to his life.
        millie asked daniel if/whether he could stay in bed for a bit longer.
        millie asked daniel if/whether robots sometimes went wrong.
        millie asked daniel if/whether he could return it to the shop.
t:（用if/whether引导的宾语从句是我们在9b第一单元中学习的内容，大家可以看到这些句子在变为宾语从句前都是一般疑问句。在这里我给大家提一个问题，如果这些句子变为特殊疑问句，我们应该如何使用宾语从句呢？今天我们就来学习用特殊疑问词引导的宾语从句。）let’s look at the following sentences.
step 2 presentation and practice
t: 1. the robot no longer knew …. when should it cook breakfast?
  2. mr jiang did not know …. what should he do with the robot?
        （如果用宾语从句来连成一句呢？）please open your books at page 29.
        the robot no longer knew when it should cook breakfast.
        mr jiang did not know what he should do with the robot.
t:（看这两个例句，同学们能不能根据上一单元学过的if/whether引导的宾语从句来总结一下规则呢？）
        规则一：我们用原来的特殊疑问词连接，不需加if/whether。
        规则二：从句部分用陈述句顺序。（这一点和if/whether引导的宾语从句是一样的。
t: so do you know how to use object clauses introduced by ‘wh-’ words now? let’s have a try. would you please finish the exercises here below on page 29. here we have 6 questions from daniel. can you finish the sentences here below?
where did mr jiang buy the robot?
when does the robot cook breakfast?
what did the robot buy at the supermarket?
how does the robot wash up?
why did mr jiang return the robot?
who will repair the robot that went wrong?
t: have you finished? let’s check your answers.
1 i’d like to know where mr jiang bought the robot.
2 can mr jiang tell me when the robot cooks breakfast?
3 i can’t imagine what the robot bought at the supermarket.
4 i want to know how the robot washes up.
5 can mr jiang explain why he returned the robot?
6 i want to ask mr jiang who will repair the robot that went wrong.

大家要特别留意动词在从句中变为陈述句顺序后发生的变化。
t: now, let’s do some exercises.
1 i’d like to know …           where is your school?
2 can you tell me …            how far is the park from here?
3 i can’t imagine …        how did they climb up the rocks?
4 can anyone explain … why does the sun always rise in the east?
5 i want to ask jim …           what will he do at the weekend?
t: let’s check your answers.
1 i’d like to know where your school is.
2 can you tell me how far the park is from here?
3 i can’t imagine how they climbed up the rocks.
4 can anyone explain why the sun always rises in the east?
5 i want to ask jim what he will do at the weekend.
t: 特殊疑问词引导的宾语从句我们就学到这里。下面我们来学习in order to和as a result这两个结构。这两个结构我们在reading部分都已经接触过了，分别用来表示“目的”和“结果”。一起来看一下书上的讲解吧。please open your books at page 30.
t: ‘in order to’ means ‘with the purpose of’. we can use ‘in order to’ to introduce the purpose of an action.  in order to意思是“为了 ……”。我们用in order to来引出一个动作的目的。

we use ‘as a result’ to introduce the result of something. 我们用as a result来引出某事的结果。
t: now let’s look at some examples.
  in order to have more spare time, i decided to buy a robot.
  i decided to buy a robot in order to have more spare time.
  the robot did all the housework. as a result, mr jiang no longer needed to get up early.

(从例句中我们可以看出in order to可以放在句首也可以放在句中，如果放在句首的话，我们要用逗号把两部分隔开。而as a result一般都放在句首，并且在它后面一般用逗号隔开。
t: now, let’s do some exercises. please open your books at page 30. please rearrange the words and add ‘in order to’ or ‘as a result’ to make complete sentences.
t: have you finished? let’s check your answers.
1 in order to watch my favourite tv programmes, i had my robot wash up after dinner. or
i had my robot wash up after dinner in order to watch my favourite tv programmes.
2 my robot made a lunch box for me. as a result, i did not have to go out for lunch.
3 in order to keep my flat as clean as new, i had my robot sweep the floor every day.  or
i had my robot sweep the floor every day in order to keep my flat as clean as new.
4 my robot caught a virus. as a result, my flat was in a mess.
5 my robot was just too much trouble. as a result, i returned it to the shop.
t: now, let’s work out the rules. we can use ‘in order to’ at the beginning or in the middle of a sentence.
t:学完这两个句型后，我们继续来学习need to的用法。
  we can use ‘need to’ to talk about something that we have to do.
t: for example:
  mr jiang no longer needed to do housework because he had a robot. (江先生不再需要做家务了，因为他有了一个机器人。)
       mr jiang needs to return his robot to the shop because it is not working. (江先生不得不把机器人还到商店去，因为它不工作了。)
t: now, let’s do some exercises. please open your books at page 31. there is something wrong with daniel’s robot. help daniel’s father give daniel some suggestions using ‘need to’.
t: have you finished? let’s check your answers.
       maybe (2) you need to check all the connections.
       maybe (3) you need to clean its cameras.
       i’m afraid (4) you need to do it yourself.
       maybe i (5) need to read the instructions again.
       i think you (6) need to return it to the shop.
t: now, let’s work out the rules. we use the base form of a verb after ‘need to’.
t: good. you’ve done a good job. now would you please read this dialogue in groups? the students on the left will be daniel. the students on the right will be mr chen.
