Ⅱ.6.cut
down　7.polluted　
8．to
solve　9.turned;
into　
10．be

Ⅲ.11.D　考查动词辨析。根据句意理解可知，第一空句子主语是you，指人，且句中有for，所以用pay；而第二空主语是It，指代的是前面提到的the
dictionary，所以这里是物作主语，应该用cost。故选D。
12．C　考查名词辨析。decision意为“决定”；condition意为“条件”；advantage意为“优势”；friendship意为“友谊”。根据上句“他既会讲英语又会讲法语”可知，会讲两种语言是他的优势。故选C。
13．C　句意：Peter，你昨晚喝得太多了。如果我没记错的话，你过去并不是这样的。used
to的否定式是didn't
use
to。
14．D　句意：“别乱丢垃圾，那会使公园看起来很丑。”“对不起，我不会了。”ugly意为“丑陋的”。
15．A　考查名词辨析。bottom意为“底部”；
circle意为“圈子”；
enemy意为“敌人”；
fridge意为“冰箱”。结合句意可知，此处指的是“从内心深处感谢他”，故选A。
Ⅳ.16.full

　　阅读下面的材料,判断下列句子是否符合短文内容。符合的填“T”,不符合的填“F”。
The
world
has
a
plastic
problem.
And
not
just
with
bottles.
Straws(吸管),
toothbrushes,
toys—all
kinds
of
plastics
are
placed
in
landfills(垃圾填埋场).
There
are
5
billion
tons
of
plastic
waste
in
the
world.
Landfills
have
a
large
part
of
it.
By
2050,
they
could
have
13
billion
tons.
Much
of
plastic
rubbish
finds
its
way
into
the
ocean.
Scientists
say
165
million
tons
of
plastic
pieces
are
floating
around
out
there.
And
most
plastic
won’t
disappear
itself.
It
will
remain
in
the
ocean
forever.
Whales
get
caught
in
plastic
fishing
nets.
Birds
die
because
of
eating
plastic
straws
and
bottle
caps.
It
endangers
ocean
life.
Plastic
rubbish
even
ends
up
in
the
food
we
eat.
Governments
are
realizing
that
recycling
may
not
be
enough.
They
are
taking
more
actions.
Though
it
is
hard
work,
it
is
still
a
solvable
problem.
In
Britain,
people
are
not
allowed
to
use
plastic
bags
except
in
hospitals.
Scotland
and
several
coastal
cities
in
the
US
stop
people
from
using
plastic
straws
as
well.
The
US
alone
throws
away
some
500
million
plastic
straws
a
day.
That’s
enough
to
circle
the
earth
twice,
“Saying
no
to
a
plastic
straw
is
an
easy
way
to
make
a
big
difference,”
Diana
Lofflin
who
started
www.strawfree.org
said.
“Do
we
really
want
to
pass
on
to
our
children
a
world
harmed
by
plastic?”
People
have
found
some
tasty
ways
to
reduce
waste.
A
company
in
India
made
the
first-ever
spoon
that
people
can
eat.
You
don’t
have
to
eat
the
spoon.
You
can
throw
it
away.
It
decomposes(分解)
in
just
a
few
days.
David
Edwards,
a
scientist
at
Harvard
University,
designed
an
eatable
bag
which
can
protect
the
food
or
drink
inside.
It
is
a
delicious
replacement
for
plastic
ones.

Ⅳ.【主旨大意】
本文是一篇说明文。文章介绍了当今世界普遍存在的塑料垃圾问题以及它的危害和一些解决方法。
16.T　由第二段的倒数第三句“Birds
die
because
of
eating
plastic
straws
and
bottle
caps.”可知,鸟类是因为吃塑料吸管和瓶盖而死亡。
17.T　根据第三段的第三句“Though
it
is
hard
work,
it
is
still
a
solvable
problem.”可知,塑料垃圾问题虽然很难解决,但是可以解决。
18.F
19.F　根据最后一段中“David
Edwards,
a
scientist
at
Harvard
University,
designed
an
eatable
bag
which
can
protect
the
food
or
drink
inside.”可知,这位科学家是哈佛大学的,应该是在美国,不是在印度。
20.T　由第一段首句“The
world
has
a
plastic
problem.”以及下文可知,全文主要介绍了世界普遍存在的塑料垃圾问题以及人们的行动。
