【语法知识】
英语中有很多单词的构成是有规律可循的。学习一些有关构词法的知识，可以帮你更好地理解和记忆单词，也可以帮你猜测词义和辨别词性。本模块我们学习一下构词法中的合成法和派生法。
一、合成法是将两个或两个以上单词合在一起构成新词的方法。
【例子】
football,
classroom,
afternoon,
without,
spaceship,
friendship,
textbook,
grandson
二、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词方法。观察下列例子，然后补全结论部分所缺内容。
【例子】
1.
able
→
unable,
smoker
→
nonsmoker,
like
→
dislike,
possible
→
impossible
2.
lead
→
mislead
3.
net
→
internet,
national
→
international
4.
tell
→
retell
5.
teach
→
teacher,
act
→
actor,
art→
artist,?compete
→
competition,
agree
→
agreement
6.
care
→careful,
use
→
useless,
comfort
→?comfortable
7.
actual
→actually,
proper
→
properly
【结论】
1.
通过观察例子
1-4
可以看出，添加在词根前的构词部分叫前缀，它多数情况下不改变原词的词性。常见的有：表示否定的
un-,
non-,
dis-,
im-；表示错误或失当的
mis-;?表示相互、交互、在一起的
inter-;
表示又、再、重复的
re-。
2.
通过观察例子
5
-
7
可以看出，添加在词根后的构词部分叫后缀，它多数情况下
改变原词的词性。常见的有：名词后缀：-er,
-or,
-ist,
-tion,
-ment
等；形容词后缀：-ful,
-less,
-able
等；副词后缀：-ly
等。
【写作练习】
许多野生动物处于濒临灭绝的危险境地，特别是许多大型动物，出于乱砍滥伐，环境的破坏，使它们的灭绝速度加快。地球是不能没有动植物，人类出为能独存，因此，我们要保护环境，采取措施改变人类的生存状况。
???请你以Protect
Wild
Animals为题，写一篇短文。谈谈我们为什么要保护野生动物，应该采取措施保护野生动物。
Protect
Wild
Animals
?
?Why
should
we
protect
wild
animals?
Do
you
know
any
of
endangered
animals?
Why
are
they
in
danger?
?
??I
think
there
are
many
endangered
animals
in
the
world,
such
as
tigers
and
pandas.
When
farmers
cut
down
trees,
tigers
can’t
hide
or
hunt.
Many
tigers
are
killed
by
people
who
want
to
sell
their
fur
for
money.
And
there
are
few
places
where
pandas
can
live.
?
??We
human
beings
could
not
live
without
all
the
plants
and
animals
around
us.
So
Protecting
wild
animals
is
very
important.
We
must
take
measures
to
keep
plants
from
being
destroyed
and
stop
animals
from
being
killed.
If
each
of
us
can
plant
a
tree
and
build
a
birdhouse,
the
world
will
be
more
beautiful.
