Object

宾语从句
I
know
him.
我认识他。
I
know
his
sister.
我认识他妹妹。
I
know
that
Tom
will
come
back
next
week.
我知道汤姆下周回来。
（以上三个句子中的“him”、“his
sister”、“Tom
will
come
back
next
week
.”在句中都是作宾语，在语法功能上他们都是相同的。）
◆由于像这样:一个句子只是作整个句子中的一个句子成分，我们习惯上把它叫作从句。由于这个从句在句中作宾语，我们把它叫宾语从句，把整个句子叫复合句。

Summary
宾语从句三要素：
引导词：
语序：
时态：
1)
that
(无意义，可省略)
2)
If&
whether
(是否，if不与or
not连用)
3)
wh&h
特殊疑问词
主+谓+其他成分
主现从任意
主过从过
事实真理一般现在时
拓展一：
关于if和whether
若宾语从句中，引导词if
=
whether，一般可通用。
2.
但是与or
not连用时，只能用whether。
e.g.我不知道他们是否会来。
I
don't
know
whether
they
will
come
or
not.
3.此外，只用whether
+
动词不定式（to
do）
e.g.
我不知道是否要去。
I
don't
know
whether
to
go.
4.介词后只能用whether。
e.g.
His
father
is
worried
about
whether
he
has
lost
his
work
.
拓展二：宾语从句的否定转移
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，从句的否定词一般要转移到主句上来，其反义疑问句的谓语和人称一般与宾语从句一致。如：
我认为他不会来我的聚会。
I
don't
think
he
will
come
to
my
party.
改反义疑问句：
I
don't
believe
that
man
was
killed
by
him,
?
was
he
？
宾语从句的否定转移
当主句的主语为I或we,谓语为think,believe,guess,know等词时，其后的宾语从句的否定词应该转移到主句上，即主句的谓语动词用否定式，而从句的谓语动词用肯定式．
I
think
you
aren’t
right.
I
don’t
think
you
are
right.
我想你是不对的．
注意：若谓语动词为hope,宾语从句中的否定词不能转移．
I
don’t
hope
you
were
ill.
I
hope
you
weren’t
ill.
我希望你没生病吧．
