Let's think 特殊情况
宾语从句简化
1.当主句的主语和从句的主语一致时，则原本由疑问词引导的宾语从句可以变成 。
1. I wonder when I shall leave for Nanjing.
=I wonder ______ ______ _____ for Nanjing.
2. I don’t know how I can deal with the problem.
=I don’t know _____ _____ ____ with the problem.
when to leave
how to deal
疑问词+to do
将下列复合句改为简单句。
Let's think 特殊情况
否定转移
I think,“she isn't clever.”（否定句）
=l ______ think ____ __ clever.
don't
she is
2.主句的谓语动词是think, believe, imagine, suppose, guess等，并且主句的主语是第一人称而且为一般现在时，从句的否定词not 一般要转移到 。
主句
I think sixteen-year-olds should be allowed to drive.
否定转移 变反义疑问句
宾语从句中，若主句谓语动词是
think, believe等表示心理活动的动词时，宾语从句不能用否定形式，
若宾语从句是否定意思时，则常将否定词not移到think,believe的前面，从而形成“形式上否定主句，实际上否定宾语从句”的现象，这种语法现象叫做否定前移。
否定前移
I don’t think sixteen-year-olds should be allowed to drive.
think, believe, suppose等词引导的宾语从句，且
主句主语为第一人称时，否定前移的用法。
I don't think he will tell lies，___ _____
will he
Let's think 特殊情况
委婉could

Could you please tell me where the bank is
Would you please tell me how far it is from here to the hospital
Let's think 特殊情况
疑问词作主语
4.当从句中疑问词作主语时，语序不变 。

Can you tell me what is wrong with you

宾语从句六注意：
一、引导词
if/whether区别
二、语序
What is the matter （怎么了？）语序不变
三 、时态
如宾语从句表客观真理或自然现象 ,仍用一般现在时
Could you tell me…
四、if,when引导宾语从句和状语从句的区别
五、特殊疑问句的简化：疑问词+to do
六、否定转移
在think , believe , suppose,imagine等动词所跟的宾语中，如果从句谓语是否定的，一般要将否定词not转移至主句谓语上去，而将从句谓语改为肯定形式。如：
that
if / whether
