How
much
is
this
T-shirt?
how
much
通常用来对价格进行提问，意为“多少钱”。
常构成句式“How
much
is/are+物品?”，回答用“It’s
/They’re+价格”。直接用价格来回答。
——How
much
is
your
sweater?
——How
much
are
these
trousers?
——It’s
123
dollars./123
dollars.
——They’re
130
yuan.
对价格进行询问时，还可用：What’s
the
price
of
…?
使用这一句型时，无论被询问的商品是单数还是复数，be动词都用is，不能用are；其答语为It’s….价格是……
——What’s
the
price
of
the
book?
——What’s
the
price
of
these
books?
——It’s
five
yuan
.
——It’s
ten

.
辨析how
much和how
many
表示“多少”，都是对名词的数量进行提问，两者区别如下:
how
much
后接不可数名词，用于提问不可数名词的数量或价格
句式：How
much
+
不可数名词
+
一般疑问句？
how
many
后接可数名词复数，用于提问可数名词的数量
句式：How
many
+
可数名词复数
+
一般疑问句?
像socks,
shoes,
trousers,
glasses,
shorts,等都是成双成对的物品，一般以复数的形式出现。
这类名词作主语时，谓语动词一般用复数形式。
e.g.
How
much
are
these
shorts?
/
How
much
are
these
socks?
这双短袜多少钱？
2)
若表示“一双，一副，一条”时则要用a
pair
of，但谓语动词用单数形式。
e.g.
The
pair
of
trousers
is
98
yuan.
a
pair
of
/
two
pairs
of
socks/shorts
(也可以用some,
many,
these,
those等词修饰)
1）
How
much
is
+　单数商品？
How
much
are
+
复数商品？
It’s
+
钱
They’re
+
钱
翻译练习：
这件红色的裙子多少钱？100元。
②这条蓝裤子多少钱？30美元.
What’s
the
price
of
+
商品？
It’s
+
钱
①这件红色的裙子多少钱？100元。
②这条蓝裤子多少钱？30美元.
dollar
可数名词，“美元”，其符号为$，其复数形式为dollars。中国的货币单位是元，其符号为￥，为不可数名词。
表价格时，用单词则放在数字之后，用符号则放在数字之前。e.g.
20
dollars
=$20
.(货币符号没有复数形式)
所有的钱数同时间、距离一样，无论多少，在句中作主语时，谓语动词都用单数形式。
e.g.
5,000
dollars
is
quite
a
lot
of
money
for
me.
Five
weeks
is
quite
a
long
time.五周是相当长的一段时间。
—Can
I
help
you?
我能帮您吗？
==
May
I
help
you?
/
What
can
I
do
for
you?
/
Is
there
anything
I
can
do
for
you?
—Thank
you，I
want
…/
Yes，please.
I’d
like…
/
No,
thanks.
I’m
just
looking
around.
/
Just
a
look.
这一句主要是英语国家里，服务员招呼客户的常用语，以表示客气和礼貌，而不说“What
do
you
want?”。
need
“需要”
当实义动词时，
need
+
n.
/
prep.
/to
do
sth.
构成否定句和疑问句时需借助助动词do/does.
e.g.
I
need
a
hat.
/
Does
your
mother
need
any
help？
当情态动词时，need
+
v原。变否定句时要在need
后加not，变疑问句时，要把need提到主语前。
e.g.
You
needn’t
do
it
again.
/
Need
he
do
his
homework
first?
How
about
this
one？one，代词，此处用于指代上文提到的sweaters中的一件。
e.g.
I
have
some
apples.
Do
you
want
one？
one
和it
均指上文出现过的名词，但其用法不同。
one
指代“同名异物”，即指代与前面事物同属一类的事物，并不是指同一个事物。如果指代同类事物中的一些，要用ones
it
指代“同名同物”，即指代上文出现过的同一事物
e.g.
This
apple
is
small.
Please
give
me
this
one.
这个苹果小，请给我一个大的。
These
books
are
mine.
Those
ones
are
lily’s.
这些书是我的，那些（书）是莉莉的。
Where’s
my
pen?
I
can’t
find
it.
look
1)系动词，“看上去，看起来”，+
adj.
e.g.
You
look
very
healthy.
The
teacher
looks
very
happy.
2)作不及物动词，“看”，加宾语时要与at连用，即
look
at.
e.g.
Look!
Here
comes
the
bus.
Look
at
the
picture,
please.
I’ll
take
it.
我买了。
此句是选好的商品并决定购买时的常用语。如果选定的物品是单数时，说“I’ll
take
it.”；如果选定的物品是复数时，应说“I’ll
take
them.”。
I’ll
=
I
will,
will是助动词，表“将要”，用于表示将来发生的动作。
Take
“买”，相当于buy/get/have。在口语中，买东西常用take.
e.g.
The
coat
is
very
cheap.
I’ll
take
it.
Here
you
are.给你
是把某物递给对方时的常说的一句话。当你购物或借东西时，也常用这句，表示“给你”。
不同情景意义不尽相同。当你乘车到站时，这句话意为“你到站了”。当寻物时，若是自己发现的常说“Here
it
is.”或“Here
they
are.”，意为“找到了”。
clothes
n.“衣服”，统指（身上的）各种服装，包括上衣，裤子等。
1）它不能直接与数词连用，但可以用these,
those，some等词来修饰。
2）clothes
本身是复数形式，作主语时，谓语动词总用复数形式。但如果用量词suit来修饰，谓语动词应和suit在单复数形式上保持一致。
e.g.
This
suit
of
clothes
is
Jim’s.
/
Those
suits
of
clothes
are
on
sale
now.
store
可数名词，“商店”，同义词为stop，store往往指百货商店。
还可做动词，“储存，储备”，e.g.
You
need
to
store
food.
buy
及物动词，“买”，反义词为sell（卖）
buy
sb.
sth.===buy
sth.
for
sb.给某人卖某物
e.g.
I
want
to
buy
my
father
some
presents.====I
want

forty,
fifty,?eighty。
(4)
21-29直到91-99，表示“几十几”，用整十位数加个位数表示，中间用连词符“-”把十位数和个位数连接起来。
