UNIT
5 WORKING
THE
LAND
Honor
the
“Father
of
Hybrid
Rice”
Yuan
Longping
As
the
old
Chinese
saying
goes,
“Humanity's
most
fundamental
relationship
is
with
what
we
eat.”Although
food
has
played
an
important
part
in
Chinese
culture
for
years,
hunger
had
been
a
huge
problem
in
the
country
until
the
1970s.However,
the
Chinese
scientist
Yuan
Longping
helped
to
fix
this
problem.
On
Sept
8,2018
Yuan,
together
with
two
other
scientists,
won
China's
2018
Future
Science
Prize,
for
his
continuous
research
on
rice.Even
on
his
88th
birthday
on
Sept
7,
he
took
part
in
the
International
Development
Forum
of
Rice
Production
in
Hunan
province.Although
he
was
recovering
from
an
illness
at
the
time,
he
was
happy
to
talk
to
reporters
about
his
latest
work
with
seawater
rice.
Yuan
has
been
conducting
research
on
rice
since
he
was
at
college.In
1964,
he
discovered
a
natural
hybrid
rice
plant.Since
then,
he
has
focused
on
developing
high?yield,
hybrid
rice
varieties.These
varieties
now
account
for
about
two
thirds
of
China's
rice
crop,
according
to
China
News.So,
it's
no
wonder
that
he's
known
as
the
“Father
of
Hybrid
Rice”.
And
thanks
to
China's
Belt
and
Road
Initiative,
Yuan's
hybrid
rice
is
helping
to
solve
food
problems
around
the
world.Indeed,
according
to
Xinhua
News
Agency,
hybrid
rice
plants
in
Kenya
produce
four
to
five
times
more
rice
than
the
country's
regular
rice
plants.
With
a
rising
reputation
around
the
world,
Yuan
delivered
a
speech
in
English
at
the
9th
Shandong
High?Level
Talents
Forum
in
Qingdao
in
2017.
The
humble
Yuan
was
simply
being
modest
during
his
speech.According
to
a
1999
article
by
CNN,
the
scientist
speaks
both
English
and
Russian
fluently.“I
never
need
an
interpreter
when
I
go
overseas,”
he
told
the
US
news
network.
But
in
spite
of
his
great
knowledge,
Yuan
understands
that
even
the
wisest
people
should
still
be
open
to
learning
new
things.“The
farmers
of
our
country
possess
rich
experience
in
planting
rice,”
he
told
Xinhua.“We
should
learn
from
them.”
开启快乐学习之旅
致敬“杂交水稻之父”袁隆平
中国古语有云:“民以食为天。”尽管美食向来都是中国文化的重要组成部分,但在20世纪70年代以前,饥荒曾一直是我国的一大问题。而中国科学家袁隆平则致力于解决这一问题。
2018年9月8日,袁隆平与另外两名科学家获得我国2018未来科学奖,以表彰其对水稻从未止步的研究。而在9月7日袁隆平88岁的生日当天,他还参加了在湖南省举行的国际稻作发展论坛。尽管当时他大病初愈,但他很乐于与记者们谈论自己关于“海水稻”的最新成果。
袁隆平在大学时代便展开了水稻研究。1964年,他找到了一株“天然杂交水稻”。从那时起,他便专注于培育高产的杂交水稻品种。据中国新闻网报道,这些品种如今占我国水稻作物的2/3。所以,袁隆平被称为“杂交水稻之父”也就不足为奇了。
得益于我国“一带一路”倡议,袁隆平的杂交水稻能帮助全球解决粮食问题。的确,据新华社报道,在肯尼亚种植的杂交水稻优良品种,平均产量是当地常规品种的4至5倍。
2017年,国际名望不断提高的袁隆平在青岛举行的第九届山东高层次人才论坛上做了一次英文演讲。
袁隆平为人谦逊,在演讲中表现得很谦虚。据CNN1999年的一篇文章报道,这位科学家能说一口流利的英语和俄语。“我出国时从来不需要翻译,”他在接受这家美国新闻媒体网站采访时表示。
尽管袁隆平学识渊博,但他深知,就算是最聪明的人也应该对学习新事物抱有一种开放的心态。“我国农民的种稻经验相当丰富,”他在接受新华社采访时表示。“我们应当向他们学习。”

本句属于“It+be+过去分词+that...”结构,句中
that
引导主语从句,主语从句本身又是一个主从复合句,从句中(so...)that
引导结果状语从句。
[思维拓展]
“It+be+过去分词+that...”结构:
it
是形式主语,that
引导的从句是真正的主语,that
仅起连接作用,不作成分。
常用动词:say,report,think,hope,suggest,believe,know
等。
该句型可转换为“Sb./Sth.+be+过去分词+不定式”(hope

Ⅱ Learning
About
Language
主语从句
?考点一 主语从句的定义和连接词 
1.定义:在复合句中充当主语的句子叫主语从句。
How
he
was
successful
is
still
a
puzzle.
他是如何成功的仍然是个谜。
2.连接词的选用
(1)that

what
的选用:that

what
都可引导主语从句。what
除了起连接作用外,还在名词性从句中充当某些成分,如主语、宾语或表语。而
that
在名词性从句中不充当任何成分,无词义,只起连接作用。
What
he
wants
is
a
storybook.
他想要的是一本故事书。
That
light
travels
in
straight
lines
is
known
to
all.
众所周知,光沿直线运动。
(2)if

whether
的选用:whether

if
尽管不充当句子成分,但含有“是否”的意思。whether

if
也有不同的用法:if
可以引导主语从句,但从句不能用于句首,而应该放在句尾,并用
it
作形式主语。whether还可以与or
not连用,语意不变。
Whether
we
will
hold
a
party
in
the
open
air
tomorrow
depends
on
the
weather.
我们明天是否在户外开晚会要视天气而定。
(3)其他连接词的选用:根据主语从句的具体意义,还可选择
who,
which,
when,
where,
why,
how
等连接词,这些连接词既有疑问含义,又起连接作用,同时在从句中充当成分。
When
we
shall
hold
our
sports
meet
is
not
decided.
我们何时举行运动会还没有决定下来。
Who
broke
the
glass
yesterday
is
not
clear.
昨天是谁打破的玻璃还不清楚。
Which
car
you
will
choose
to
buy
makes
no
difference.
你选择买哪辆车不会有任何区别。
(4)whatever

whoever
的选用:whatever

whoever
在主语从句中不含疑问意义,不仅起连接作用,还在从句中作成分。whatever
相当于
anything
that;
whoever
相当于
anyone
who。要注意
whatever,
whoever
引导的主语从句和让步状语从句的区别。试比较:
无论谁破坏法律,都应受到惩罚。
Whoever
breaks
the
law
should
be
punished.(=Anyone
who
breaks
the
law
should
be
punished.)
(whoever
引导的是主语从句)
Whoever
breaks
the
law,
he
should
be
punished.(=No
matter
who
breaks
the
law,
he
should
be
punished.)
(whoever
引导的是让步状语从句)
?考点二 由
it
作形式主语的主语从句 
1.由
that
引导的主语从句,在大多数情况下会放到句子的后面,而用
it
作形式主语。
It
is
well?known
that
the
earth
moves
around
the
sun.
众所周知,地球围绕太阳转。
提示:
需要注意的是,it
作形式主语代替主语从句时,要注意和
as
引导的定语从句的区别。试比较:
据报道,美国遭到恐怖分子的袭击。
It
was
reported
that
the
US
was
under
the
terrorist
attack.(it
代替主语从句,句中有
that,无逗号)
As
was
reported,
the
US
was
under
the
terrorist
attack.(as
引导定语从句,句中无
that,有逗号)
2.用
it
作形式主语的常见句型
(1)It+be+形容词+that
从句
这类形容词有
necessary,
essential,
clear,
true,
strange,
important,
possible,
likely等。需要注意的是,当形容词是
necessary,
strange,
important,
essential
等时,主语从句的谓语用“(should+)动词原形”,即从句要用虚拟语气。
It
is
necessary
that
you
(should)
master
the
computer.
你有必要精通电脑。
It
is
important
that
a
student
learn
English
well.
学生学好英语很重要。
It's
clear
that
they
badly
need
help.
很明显,他们急需援助。
(2)It+be+名词(词组)+that
从句
这类名词(词组)有
a
fact,
a
good
idea,
a
pity,
a
shame,
no
wonder等。
It's
a
pity
that
you
missed
the
film.
你没有看那部电影真是太遗憾了。
It's
no
wonder
that
you're
so
tired.
难怪你这么累。
(3)It+be+过去分词+that
从句
这类过去分词有
reported,
well?known,
hoped,
thought,
expected,
said,
believed,
suggested,
ordered等。当过去分词是
suggested,
advised,
ordered,
requested,
insisted,
required
等时,主语从句的谓语用“(should+)动词原形”,即从句要用虚拟语气。
It
is
suggested
that
the
meeting
be
put
off.
有人建议会议延期召开。
It's
said
that
Mr
Green
has
arrived
in
London.
据说格林先生已到达伦敦。
(4)It+不及物动词(短语)+that
从句
这类不及物动词(短语)有
seem,
happen,
occur,
matter,
make
a/no
difference等。
It
seems
that
they
will
win
the
game.
看起来他们好像会赢得这场比赛。
It
happened
that
I
had
no
money
with
me
that
day.
碰巧那天我身上没带钱。
?考点三 主语从句需注意的问题 
1.that
引导的主语从句置于句首时,that
不能省略;如果用
it
作形式主语,主语从句的引导词
that
通常也不可省略。
That
he
was
ill
yesterday
is
known
now.
大家都知道他昨天生病了。
That
you
don't
like
him
is
none
of
my
business.
你不喜欢他不关我的事。
2.if
引导主语从句时只能用
it
作形式主语,而把主语从句放在句末。
It
is
uncertain
if
he
will
leave
for
Beijing
tomorrow.
明天他是否去北京还不敢肯定。
3.从句的语序:在任何情况下,主语从句都用陈述语序。
Who
did
this
is
still
unknown.
这件事是谁做的还不知道。
What
surprised
me
most
was
that
the
little
girl
could
play
the
violin
so
well.
使我感到惊讶的是,这个小女孩的小提琴拉得太好了。
4.单个的主语从句作主语时,谓语动词一般用单数形式。但
what

who
引导主语从句时,谓语动词的形式应与作表语的名词保持一致。
What
we
need
are
more
personal
computers.
我们需要的是更多的个人电脑。
What
we
need
is
more
time.
我们需要的是更多的时间。

As
for
chemical
fertilisers,
crops
grown
with
them
usually
grow
too
fast
to
be
rich
in
nutrition.
至于化肥,用它们种植的作物通常生长得太快,无法提供丰富的营养。
[句式分析]
too
fast
to
be...是too...to...结构,该结构意为“太……以致不……,太……而不能……”。其中too是副词,用来修饰形容词/副词,to是动词不定式符号。
The
boy
is
too
young
to
understand
the
story.
这个男孩太小,理解不了这个故事。
[思维拓展]
使用too...to...结构时应注意:
(1)句子主语与构成不定式的动词在逻辑上是动宾关系,且构成不定式的动词是及物动词时,不定式中的动词后不能跟宾语。
Tom
spoke
too
quickly
for
us
to
understand.
汤姆说话太快了,我们听不懂。
(2)句子主语与构成不定式的动词在逻辑上是动宾关系,且构成不定式的动词是不及物动词时,要在动词后加上适当的介词。
The
house
is
too
small
for
the
family
to
live
in.
房子太小,那家人住不下。
(3)too...to...结构并非总是表示否定意义,在以下几种情况中,too...to...结构表示肯定意义:
①not置于动词不定式前,构成too...not
to...结构时,原来表示否定意义的不定式再次受到否定,转而表示肯定意义,该结构意为“太……不会不……”或“非常……必定能……”。
He
is
too
careful
not
to
have
noticed
that.
他非常小心,肯定注意到了那一点。
②too...to...结构前有not,never,no
longer,but,only等词时,这一结构也表示肯定意义。
It
is
never
too
old
to
learn.
活到老,学到老。
③too...to...结构中,too后为anxious,eager,glad,happy,pleased,excited,ready,satisfied,kind,willing等表示态度、心情、倾向等的形容词时,too相当于very
much(极其,十分,非常),此时该结构表示肯定意义。
He
is
too
ready
to
help
others.
他十分乐意帮助别人。
He
is
too
pleased
to
receive
the
pretty
gift.
收到这份漂亮的礼物,他非常高兴。

What
keeps

that

farming

the

阻止他们这样做的原因是化学农业满足了世界各地对粮食的巨大需求。
[句式分析]
这是一个复合句。What
keeps
them
from
doing
so是主语从句;that
chemical
farming
serves
the
high
demand
for
food
around
the
world是同位语从句。其中keep...from
doing
so是keep...from
doing
sth.“阻止……做某事”结构。同义表达还有:stop/prevent
sb.(from)
doing
sth.阻止某人做某事
[方法规律]
这三个结构的主动语态中只有keep...from...中from不能省略;在被动语态中,三个from均不可省略。

据估算,现在中国国内消费的大米有大约百分之六十来自袁隆平的杂交水稻……
本句属于“It+be+过去分词+that...”结构,句中
that
引导主语从句,主语从句本身又是一个主从复合句,从句中(so...)that
引导结果状语从句。
“It+be+过去分词+that...”结构:
it
是形式主语,that
引导的从句是真正的主语,that
仅起连接作用,不作成分。

be...是too...to...结构,该结构意为“太……以致不……,太……而不能……”。其中too是副词,用来修饰形容词/副词,to是动词不定式符号。
使用too...to...结构时应注意:
(1)句子主语与构成不定式的动词在逻辑上是动宾关系,且构成不定式的动词是及物动词时,不定式中的动词后不能跟宾语。
(2)句子主语与构成不定式的动词在逻辑上是动宾关系,且构成不定式的动词是不及物动词时,要在动词后加上适当的介词。
(3)too...to...结构并非总是表示否定意义,在以下几种情况中,too...to...结构表示肯定意义:
①not置于动词不定式前,构成too...not
to...结构时,原来表示否定意义的不定式再次受到否定,转而表示肯定意义,该结构意为“太……不会不……”或“非常……必定能……”。
②too...to...结构前有not,never,no
longer,but,only等词时,这一结构也表示肯定意义。
③too...to...结构中,too后为anxious,eager,glad,happy,pleased,excited,ready,satisfied,kind,willing等表示态度、心情、倾向等的形容词时,too相当于very
much(极其,十分,非常),此时该结构表示肯定意义。

本单元的写作任务是写辩论报告,这类文章要求用一定的理由说明自己对事物或问题的见解、看法,属于议论文的范畴。
1.篇章特点
议论文是一种以议论为主要表达方式的文体,就是摆事实、讲道理,并要求通过多方面的分析,把道理说通,说透。议论文有三要素,即论点、论据和论证。论点的基本要求是观点正确,认真概括,有实际意义,恰当地综合运用各种表达方式;论据的基本要求是真实可靠,充分典型;论证的基本要求是推理必须符合逻辑。
2.注意事项
写作时应注意:
第一,要提出正确鲜明的论点。一般来说,要把论点写在篇首或段首,这样能起到纲举目张的效果,让读者读起来更容易把握文章思路。
第二,要重视论据这一关的阐述。论据就是用来证明论点的事实和道理。要有足够的论据,可以列举生活的实例来证明论点。
第三,论证是议论文中必不可少的部分。一段完整的议论,只有通过论证证明论据和论点之间的内在逻辑关系,才能将论据和论点融为一体,也才能构成一篇完整的、有说服力的文章。
3.写作形式
此类作文一般有两种写法。
(1)文章分三部分进行论述:
第一部分:提出论点
第二部分:给出论据
第三部分:得出结论
(2)文章分四部分进行论述:
第一部分:说明辩论的主题、参与者等
第二部分:列举正方的观点及其理由
第三部分:列举反方的观点及其理由
第四部分:阐明自己的观点
