一、从词性用法上比较
1.
good
只用作形容词,不用作副词,其副词形式用
well。如:
he
speaks
good
english.
他的英语说得好。
he
speaks
english
well.
他的英语说得好。
2.
well
既可用作副词,也可用作形容词。用作形容词时,其用法很有限,只表示“健康的”“恰当的”或“令人满意的”等。如:
she
is
very
well.
她身体很好。
things
are
well
with
us.
我们事事如意。
注:一般说来,well
用作形容词时,只用作表语而不用作定语(如上例),但在美国英语中,well
表示“身体健康”时有时也可用作定语。
二、从相关短语用法上比较
be
good
at
与
do
well
in:两者均可表示“擅长”。如:
he
is
good
at
languages.
他擅长学语言。
she
is
good
at
telling
stories.
她擅于讲故事。
they
all
did
very
well
in
the
examination.
他们这次都考得很不错。
注:表示擅长某一学科时,也可用be
good
in。如:
he
is
good
at
[in]
maths.
他擅长数学。
2.
as
good
as
与
as
well
as:用于本义时,两者均可表示“与……一样好”,但
good
是形容词,而
well
是副词。如:
他说英语说得跟她一样好。
正:he
speaks
english
as
well
as
her.
正:his
english
is
as
good
as
hers.
但是,用于引申义时,两者的意思很不相同:as
good
as
意为“几乎”“差不多”(=almost),as
well
as
意为“而且”。如:
the
work
is
as
good
as
finished.
工作差不多干完了。
he
as
good
as
said
i’m
a
liar.
他无异于说我撒谎。
she’s
clever
as
well
as
beautiful.
她不但漂亮,而且聪明。
as
well
as
breaking
his
leg,
he
hurt
his
arm.
他不但摔断了腿,
而且还伤了胳膊。
