二、找出不可数名词，在横线上打勾，并将可数名词变成复数形式。
homework knife advice money
housework drink blood music
honey heat mouth bread
information milk cow juice
homework knife advice money
housework drink blood music
honey heat mouth bread
information milk cow juice
答案
homework √；knives；advice √；money √；housework √；drinks；blood √；music √；honey √；heat √；mouths；bread √；information √；milk √；cows；juice √
解析
不可数名词通常指无法直接用数量计算的事物，如抽象概念、物质名词等，无复数形式；可数名词有单复数之分，复数形式变化规则包括一般加-s，以f/fe结尾变v加-es，不规则变化等。
homework（不可数）；knife→knives；advice（不可数）；money（不可数）；housework（不可数）；drink→drinks；blood（不可数）；music（不可数）；honey（不可数）；heat（不可数）；mouth→mouths；bread（不可数）；information（不可数）；milk（不可数）；cow→cows；juice（不可数）

三、单项选择。
() 1. It is good for the fish to have water plants in the tank to keep the water clean.
A.little
B.a little
C.few
D.a few
() 1. It is good for the fish to have water plants in the tank to keep the water clean.
A.little
B.a little
C.few
D.a few
答案
D
解析
题干意思是“对于鱼来说，在鱼缸里种植_______水草来保持水的清洁是有益的”，water plants为可数名词，此处应用修饰可数名词的短语。a few表示“一些、几个”，后接可数名词复数，few含否定意义，表示“几乎没有”；a little表示“一点儿、一些”，后接不可数名词，little含否定意义。根据题干要保持水清洁，应种植一些水草，且water plants为可数名词复数，所以填a few。
() 2. There’re interesting places in China.
A.quite a few
B.quite a little
C.few
D.little
A.quite a few
B.quite a little
C.few
D.little
答案
A
解析
题干中“interesting places”为可数名词复数。选项B“quite a little”修饰不可数名词，排除；选项D“little”修饰不可数名词，且表否定含义，排除；选项C“few”修饰可数名词复数，但表否定含义，不符合语境；选项A“quite a few”修饰可数名词复数，表肯定含义，符合题意。
() 3. Sorry, I can give only water to you.
A.a few
B.a little
C.few
D.little
A.a few
B.a little
C.few
D.little
答案
B
解析
water是不可数名词，a few和few修饰可数名词，排除A、C；only后接肯定含义的词，a little表肯定，little表否定，选B。
() 4. There are people in front of me. I have to wait for a long time.
A.very little
B.only a few
C.quite a few
D.quite a little
A.very little
B.only a few
C.quite a few
D.quite a little
答案
C
解析
people是可数名词复数，little和a little修饰不可数名词，排除A、D；根据“I have to wait for a long time”可知人很多，only a few表示“只有几个”，quite a few表示“相当多”，选C。
()5. — David often plays alone. He has friends.
— Yes. He is too shy to make friends.
A.little
B.a little
C.a few
D.few
— Yes. He is too shy to make friends.
A.little
B.a little
C.a few
D.few
答案
D
解析
friends是可数名词复数。little和a little修饰不可数名词，排除A、B；a few表示“一些”，few表示“几乎没有”。由“David often plays alone”和“He is too shy to make friends”可知他几乎没有朋友，选D。
() 6. — Would you like some milk in your tea? — Yes, just .
A.much
B.a little
C.a few
D.little
A.much
B.a little
C.a few
D.little
答案
B
解析
milk是不可数名词，排除C（a few修饰可数名词）。根据Yes可知需要肯定含义，排除D（little表否定）。just a little表示“只要一点点”，符合语境；much表示“很多”，与just搭配不当。
() 7. She wrote a lot of books, but are good ones.
A.any
B.some
C.few
D.many
A.any
B.some
C.few
D.many
答案
C
解析
本题考查不定代词的用法。根据“but”可知前后为转折关系，前半句说她写了很多书，后半句应表示“很少是好的”，few表示“很少，几乎没有”，具有否定意义，符合语境。any一般用于否定句和疑问句；some一般用于肯定句；many表示“许多”，均不符合题意。
() 8.There is some on the plate.
A.apple
B.bread
C.banana
D.sandwich
A.apple
B.bread
C.banana
D.sandwich
答案
B
解析
There is后接不可数名词或可数名词单数，some后接不可数名词或可数名词复数。选项A、C、D均为可数名词单数，some后需用复数形式；选项B为不可数名词，符合要求。

A.little
B.few
C.a few
D.a little
A.little
B.few
C.a few
D.a little
答案
D
解析
water是不可数名词，little和a little修饰不可数名词，few和a few修饰可数名词，排除B、C。根据Yes可知有一些水，a little表示“一些”，little表示“几乎没有”，选D。
() 10. You can only eat ice creams at a time. It isn’t a healthy diet.
A.little
B.few
C.a little
D.a few
A.little
B.few
C.a little
D.a few
答案
D
解析
本题中“ice creams”为可数名词复数形式，“a few”用于修饰可数名词复数，表示“几个”；“few”表示否定意义，几乎没有；“a little”用于修饰不可数名词，表示“一点”；“little”表示否定意义，用于不可数名词。根据题意“你一次只能吃几个冰淇淋”，这里需要表示肯定的意义，所以应选“a few”。
