My
sister
Amy
and
I
always
try
to
stop
people
dropping
cigarette
butts(烟蒂)
everywhere.We
have
done
this
11
seven
years.
One
day，we
were
walking
in
our
hometown
and
saw
hundreds
of
cigarette
butts
on
the
ground.They
made
the
town
look
so
dirty
12
we
decided
to
start
a
group
to
make
people
stop
dropping
cigarette
butts.We
called
it
“No
Butts
About
It”．
At
13
，we
drew
pictures
with
letters
“The
earth
is
not
14
ashtray(烟灰缸)”
on
them.We
put
up
the
pictures
in
our
hometown—in
parks，on
walls，
and
along
roads.We
wanted
to
make
people
15
that
dropping
butts
did
harm
to
the
earth.
Most
smokers
don’t
think
that
dropping
butts
harms
the
earth.
But
it
does！All
rubbish
does.
Later，we
wrote
to
factories
and
offices
and
asked
them
for
money
16
ashtrays
and
gave
them
to
smokers.We
wanted
smokers
to
carry
the
ashtrays
17
them
so
they
didn’t
have
to
drop
butts.
Now
we
are
trying
to
get
cigarette
companies
to
put
18
ashtray
in
each
pack
of
cigarettes.Some
companies
would
do
it.
Many
people
have
started
to
join
our
group
since
it
began.
Today
there
are
45
other
groups
of
“No
Butts
About
It”
in
America.And
there
are
also
groups
in
England，Australia
and
India！Many
newspapers
19
about
my
sister
and
I
over
the
last
seven
years.And
we
have
won
many
prizes
for
our
good
work.
But
we
are
not
20
in
prizes.We
just
want
to
make
the
earth
a
better
and
cleaner
place
for
animals，plants
and
people.One
day
it
will
be.

语法聚焦
构词法
把两个或两个以上的词组合在一起或在一个词的基础上进行变化，从而得到一个新词，即为“构词”。在初中阶段,我们主要学习三种构词法：合成法、派生法、转化法。
构词法
举例
home+work—homework
hard+working—hardworking
down+load—download
wh合成法：把两个或两个以上独立且语义不同的单词合在一起，构成一个新词，这种构词法叫合成法。常见的合成词有合成名词、合成形容词和合成动词
派生法：派生法也叫前缀、后缀构词法，即由一个词根加上前缀或后缀构成另一个词的构成方法。
1.
前缀
添加在词根前的构词部分叫前缀，多数情况下它不改变原词的词性。常见的有以下几种：
(1)im-，un-，in-，dis-,non-等，表示否定。
(2)re-，表示“重复”。
(3)mis-，表示“错误地”。
(4)anti-，表示“反对；防止”。
(5)inter-，表示“相互；交互；在……之间”。
2.
后缀
添加在词根后的构词部分叫后缀，多数情况下它改变原词的词性。常见的有以下几种：
(1)名词后缀：-er，-or，-ist，-tion，-ment等。
(2)形容词后缀：-ful，-less，-able等。
(3)副词后缀：-ly。
(4)数词后缀：-th，-teen，-ty等
possible—impossible，happy—unhappy，correct—incorrect，
agree—disagree，
smoker—nonsmoker
build—rebuild
understand—misunderstand
war—antiwar
national—international
read—reader，visit—visitor，piano—pianist，
suggest—suggestion，develop—development
care—careful，use—useless，believe—believable
slow—slowly
four—fourth，fourteen，forty
转化法：转化法是指将一种词类转化为另一种词类而词形不变。转化后的意义往往与之前的意义联系密切。常见的有动词转化为名词、名词转化为动词、形容词转化为动词
ride
v.
骑；乘—n.
骑马；乘车
record
n.记录—v.最佳纪录
clear
adj.(天气)晴朗的—v.

A.回答问题（核心素养：语言能力）
阅读下面这篇文章，根据所提供的信息，回答问题。
Ryan
Hickman
is
a
boy
from
the
US.
If
there’s
one
thing
that
he
loves,
it’s
recycling.
His
love
of
it
led
him
to
start
his
own
business
and
save
more
than
10,000
dollars
for
college.
But
you
know
what,
he’s
only
seven
years
old!
Four
years
ago,
Ryan
was
taken
to
a
recycling
centre
by
his
father
to
sell
some
water
bottles.
The
boy
liked
sorting
(分类)
and
putting
the
bottles
into
the
recycling
读写综合
machine
very
much.
He
was
so
excited
about
it
that
he
wanted
something
many
adults
had
never
ever
dreamed
of:
having
his
own
recycling
company.
With
the
help
of
his
parents,
Ryan
gave
plastic
bags
to
all
his
neighbours.
He
wanted
everyone
to
start
saving
plastic
and
glass
bottles
and
cans
for
him.
So,
Ryan’s
Recycling
Company
was
born.
So
far,
Ryan’s
company
has
made
more
than
10,000
dollars
from
recycling
cans
and
bottles.
It
also
sells
T-shirts
online.
All
the
money
it
gets
from
selling
the
shirts
is
given
to
an
animal
care
centre.
Although
sorting
the
rubbish
is
a
lot
of
work,
the
young
businessman
takes
care
of
it
every
day,
as
long
as
he
finishes
his
homework
first.
Ryan
thinks
other
people
should
start
recycling,
too,
not
only
because
it
brings
about
some
money,
but
also
because
it
helps
the
world.
Answer
the
following
questions.
1.
How
much
money
did
Ryan
save
for
college
by
recycling?
_______________________________________________
He
saved
more
than
10,000
dollars
for
college.
2.
How
old
was
Ryan
when
he
wanted
to
have
his
own
company?
________________________________________________
3.
What’s
the
name
of
Ryan’s
company?

4.
What
place
did
Ryan
give
the
money
from
selling
T-shirts
to?
________________________________________________
5.
Why
does
Ryan
think
people
should
recycle?
________________________________________________
________________________________________________
He
was
three
years
old.
It’s
Ryan’s
Recycling
Company.
He
gives
it
to
an
animal
care
center.
Because
it
can
bring
about
some
money
and
help
the
world.
