  句型：the robot no longer knew when it should cook breakfast.

        in order to have more spare time, i need to buy a robot.
        i need 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.
        mr jiang no longer needed to do housework because he had a robot.
        mr jiang needs to return his robot to the shop because it is not working.
二. 要點點撥
1. in order to 表示“為了…..”，強調目的，后面接動詞原形。可以放在句首或句中。其否定形式為in order not to do sth.可以和so that 或 in order that 引導的狀語從句互換。
she spoke loudly in order to let us hear hear.
=she spoke loudly in order that we could hear hea.
=she spoke loudly so that we could hear her.
也可以和so as to do sth互換。
i finished all the homework quickly so as to play football.
=i finished all the homework quickly in order to play football.
注：in order to 可以在句首或句中，而so as to 只能在句中。
2. as a result 表示“因此，所以”，常用于兩句之間，用逗號隔開。
as a result of “后果，結果”，后接名詞（短語）或動詞-ing形式。
he got up late. as a result,he missed the train.
=he missed the train as a result of getting up late.
3. need 作情態動詞，表示“需要”，沒有人稱和數的變化，后接動詞原形；否定句在need后加not,也可縮寫成needn’t 疑問句把need提前。
1）i need tell you that he has gone.
2) you needn’t finish the work today.
3)—need i leave now?
 ---no, you needn’t.
need作名詞，“需要”.
we should help people in need.
4.直接引語轉換為間接引語時應注意
  a 人稱的變化：一隨主，二隨賓，第三人稱不更新。
  b 時態的變化：引述動詞為過去式時，從句中的時態相應往前推一個，一般現在時變過去時
  c 一般疑問句的改寫：添加if 或whether 后用陳述句語序。
特殊疑問句用特殊疑問詞引導
d 客觀真理永遠用一般現在時
