?观察领悟
【我的领悟】
句①②③中画线部分都是主语从句，句①中为that引导主语从句，句②中为whether引导主语从句，句③中为what引导主语从句。
本单元语法主要介绍的是主语从句，主语从句是名词性从句的一种，在复合句中作主语，相当于名词。主语从句的位置可以在句首，也可以用it作形式主语，主语从句放在后面。
□主语从句
一、主语从句的基本用法
1．主语从句的引导词
类别
例词
用法
从属
连词
that,
whether
在从句中均不作成分，只起连接作用；that无实义，whether表示“是否”。
连接
代词
who,
what,
which,
whoever,
whatever等
在从句中作主语、宾语、表语、定语等成分。
连接
副词
when,
where,
how,
why等
在从句中作时间、地点、方式、原因状语等成分。
Whoever
breaks
this
law
deserves
a
fine.
触犯本法者应予以罚款。
Whichever(of
you)comes
in
first
will
receive
a
prize.
(你们中)谁先进来谁得奖。
When
we
will
have
a
meeting
is
an
important
question.
我们何时举行一次会议是个重要的问题。
Where
we
shall
do
the
test
is
still
under
discussion.
我们在什么地方做这个实验还在讨论。
What
I
have
seen
today
has
made
a
very
deep
impression
on
me.
今天我的所见所闻给我留下了非常深刻的印象。
【名师点睛】
1．主语从句中连接词的选择技巧
(1)根据连接词在从句中所作的语法成分。
(2)根据连接词在从句中的意义。
2．it作形式主语
为保持句子平衡，常把主语从句后置，而用形式主语it代替。it作形式主语时常用于以下句型：
句型
用法
It＋系动词＋形容词＋主语从句
常用于此句型的形容词有important,
(un)likely,
possible,
necessary,
natural,
wrong等。
It＋系动词＋名词＋主语从句
常用于此句型的名词有fact,
idea,
honour,
question,
pity等。
句型
用法
It＋be＋过去分词＋主语从句
常用于此句型的过去分词有known,
proved,
said,
decided,
suggested,
thought等。
It＋不及物动词＋主语从句
常用于此句型的动词有appear,
happen,
seem,
occur,
matter等。
It’s
possible
that
he
has
been
to
Beijing.
他有可能去过北京。
It’s
a
pity
that
you
didn’t
attend
the
meeting.
你没参加这次会议太可惜了。
It
seems
that
it
is
going
to
rain.
看起来好像要下雨。
It
is
important
that
he
(should)
know
about
this.
他应该知道此事是重要的。
It
is
suggested
that
the
meeting
(should)
be
put
off.
有人建议会议延期召开。
【名师点睛】
①在“It＋be＋过去分词＋主语从句”结构中，过去分词若为suggested/ordered/required/advised等，主语从句中的谓语用“(should)
do”。
②在“It＋be＋形容词＋主语从句”结构中，若形容词为important/necessary/strange等，主语从句中的谓语用“(should)do”。
二、主语从句中应注意的问题
1．从句要用陈述语序
How
he
succeeded
is
still
a
puzzle.
他是如何成功的仍然是个谜。
2．主谓一致
(1)从句作主语时，主句的谓语一般用单数形式。
Where
he
will
get
a
job
after
graduation
has
puzzled
him
much.
毕业后到哪儿找一份工作使他很困惑。
(2)what引导主语从句时，有时主句谓语动词应与主句中作表语的名词保持一致。
What
the
school
needs
most
are
books.
这所学校最需要的是书。
(3)如果由and连接两个或两个以上的主语从句作主语时，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
and
where
they
will
hold
the
meeting
is
not
clear.
他们何时何地召开会议还不清楚。
When
they
will
start
and
where
they
will
go
have
not
been
decided
yet.
他们将在什么时候动身以及要去哪里还没定下来。

In

of
the
development
of
modern
agriculture,
chemical
agriculture
and
organic
agriculture
are
two
key
words,
about
which
there
are
various

Chemical
agriculture
has
many
disadvantages.
There
is
no
doubt
that
the
chemicals
staying
inside
the
crops
can
lead
to
cancer
or
other
illnesses.
Besides,
the
vegetables
grow
so
fast
that
they
contain
little
nutrition.
Organic
foods
are
becoming
increasingly
popular
with
customers.
The
first
reason
is
that
people
attach
great
importance
to
health.
Second,
organic
produce
simply
uses
natural
fertilisers,
making
vegetables
and
fruit
tasty
and
nutritious.
So
it
is
wiser
to
choose
organic
food.

version：
With
the
development
of
society,
agriculture
has
also
changed
a
lot
in
many
aspects.
First
of
all,
nowadays
most
farmers
grow
crops
with
the
help
of
modern
machines
instead
of
planting
crops
with
their
hands.
As
a
result,
modern
farmers
no
longer
need
to
work
so
hard
as
before.
And
the
output
and
working
efficiency
are
also
improved
greatly,
which
contributes
a
lot
to
social-economic
development.
But
modern
agriculture
also
has
harmful
effect
on
our
society.
For
example,
the
fertilisers
and
pesticides
used
in
modern
agriculture
have
destroyed
the
environment
badly,
while
traditional
agriculture
does
not
cause
such
kind
of
problem
at
all.(共16张PPT)

这个句子的真正主语是从句that
about
60
percent...per

is
said/believed/reported
that...;有时,该句型可以转换为“Sb/Sth+be

1.主语从句的引导词
语法精析

(1)由连词that引导的主语从句:引导词that无含义,在句中不做成分,不可以省略。
That
you
will

That
you
are
so
indifferent

(2)由连词
whether引导的主语从句:whether表示“是否”,在句中不做成分,不可以省略。

still
unknown.

语法精析

(3)在由连接代词who,whose,whom,which,what,whoever,
whomever,whichever,whatever引导的主语从句:其连接代词在句中起名词性作用,充当一定成分。

(1)在“It

(2)在“It

1.从句要用陈述语序
How
he
succeeded
finally
is
still
a
puzzle.
他最后是如何成功的仍然是个谜。
语法精析

2.主语为从句的主谓一致
(1)主语为从句时,谓语动词一般要用单数形式,但如果what引导的从句做主语,代表复数概念(常可从表语上看出)时,谓语动词常用复数形式。
What
I
need
is
your
help.
我所需要的是你的帮助。
What
the
school

books.
这所学校最需要的是书。

(2)如果由and连接两个或两个以上的主语从句做主语时,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

他们将在什么时候动身以及要去哪里还没定下来。
When

他们何时何地召开会议还不清楚。
语法精析

3.需要辨别以下几组引导词
(1)whatever和whoever
whatever和whoever可以引导主语从句,并在从句中做主语、宾语、表语等。此外,它们还可以引导让步状语从句,可以转换成no
matter
what/who的形式。
Whatever
she
did
was
right.
她做的一切都是对的。(主语从句)
Keep
calm,whatever/no
matter
what
happens.
不管发生什么事都要保持镇静。(让步状语从句)
语法精析
即学即练
(2)that和what
what既有引导主语从句的作用,同时又在从句中做句子成分(主语、宾语、表语等)。这时what相当于all
that/everything
that...,常译成“……的(东西、事情、话等)”;而that只起连接作用,本身无实际意义,在从句中也不担当任何句子成分。但that引导的主语从句放在句首时,不能省略that。

he

【语篇导读】由“杂交水稻之父”袁隆平及其团队研发的第三代杂交水稻去年10月21日至22日首次公开测产，测产结果是第三代杂交水稻表现优秀。袁隆平为中国的建设和发展做出了巨大贡献，与屠呦呦等七位科学家一起被授予“共和国勋章”。
The
third-generation
hybrid
rice
developed
by
Yuan
Longping,
the
“father
of
hybrid
rice”，and
his
team
underwent
its
first
public
yield
monitoring①
from
Oct.
21
to
22
last
year
and
achieved
high
output.
The
final
yield
of
the
tested
variety②，G3-1S/P19,
came
to
1,046.3kg
per
mu,
based
on③
two
plots
of
land
in
Qingzhu
Village
under
the
city
of
Hengyang
in
central
China’s
Hunan
Province.
Experts
agreed
that
the
rice
has
a
stout
stem,
fertilizer
tolerance④，lodging
resistance⑤，large
panicle
and
more
grains.
Unlike
the
previous
two
generations
that
required
a
large
amount
of⑥
water
and
fertilizers
as
well
as
demanding
growing
conditions
and
technological⑦
support,
the
third-generation
hybrid
rice
is
easier
to
be
cultivated⑧
by
ordinary
farmers.
【1】Some
previous
high-yielding
hybrid
rice
varieties
in
China
took
160
to
even
180
days
from
sowing
to
harvesting,
while
the
figure
was
shortened
to
around
125
days
for
the
new
variety.
【2】Yuan
Longping,
who
has
made
great

to
the
construction
and
development
of
the
PRC,
has
been
awarded
the

句法分析
句中是making
it
ready...动词-ing形式短语做结果状语。动词-ing形式短语做结果状语,相当于一个并列谓语,所表示的是谓语动词的直接结果,是意料中的结果。
动词-ing形式短语做结果状语时常用逗号与主句隔开,表示与主句的动作之间有必然的因果关系,有时在其前加副词thus;动词不定式做结果状语往往表示出乎意料的结果或不好的结果,而且不定式前常加only。在这种情况下,不定式的逻辑主语也可能是全句的主语。
