Food List
Food
Brainstorm：What kind of food and drinks should we prepare
Drinks
I have two boxes of food and drinks. Let’s see what’s inside.
Box 1
Choose the different one and tell the reasons.
apple bread lemon pear
Reason 1: The apple, pear and lemon are fruits.
But bread is not fruit.

Reason 1: Milk, juice and cola are drinks.
But the carrot is a kind of vegetable.

Countable or uncountable

water
milk
pepper
chocolate
cucumber
meat
a lemon a pear a carrot a strawberry
an apple an egg an orange an onion
Think：What food do we have
Conclusion 1：
We can use numbers or the article(a/an) with countable nouns.
Part 1
If the countable noun begins with
a consonant sound, we use “a”.
辅音音素开头用不定冠词a
singular nouns (sing.)
Rule 1
If the countable noun begins with
a vowel sound, we use “an”.
元音音素开头用不定冠词an
Tip: 一有元音音素现，an就闪亮来相伴
h是辅音字母，但在hour中不发音，发元音的是o，
用an
“a” VS “an”
an hour
/a /
a hat
/h/
h是辅音字母，在hat中发辅音，用a
Practice
an umbrella
/ /
u是元音字母，在umbrella中发音是元音，用an
a unit
/ju /
u是元音字母，但在unit发音是辅音用a
“a” VS “an”
Practice
1. _____ book _____ egg _____ hamburger
2. _____ tomato _____ hour _____ carrot
3. _____ English teacher _____ American plane
4. _____ old bike _____ tall tree _____ orange
5. _____ umbrella _____ useful umbrella
6. _____ apple _____ big apple half _____ hour

Part 2
To have a class party, we need more of them!
three lemons five pears some carrots
a lot of stawberries
many apples

a box of oranges
four kilos of onions
To have a class party, we need to buy:
We add “s” to most nouns.
If the noun ends with a consonant + y, we should change “y” into “ies”.
Rule 1 plural nouns (pl.)
Attention: “元音字母+y”结尾，直接加s变复数。
如：a toy-two toys
And we still need to go to the Dayang Supermarket to buy 4 glasses of milk tea,3 boxes of peaches, tomatoes, potatoes to make special dishes
with the help of knives.
Watch and say:What will we need
We should add “es” after the nouns ending with “s”, “sh”, “ch” or “x”.
We change “f”/“fe” into “ves” in the words ending with “f”/“fe”, such as “knife” “scarf” “leaf” “half” and “life”.
We add “es” after the words ending
with “o”, such as tomato, potato,hero.
Rule 2
Attention: 其他以o结尾的无生命的单词常常直接+s构成复数。
如：a photo-two photos,
a piano-two pianos.
Are there any other special situations
Some special plural nouns
Rule 3

We can’t use numbers or the article(a/an) with uncountable nouns.We can’t add “s”/“es” after [un.]
借助some, much,a little, little, a lot of , lots of等来表示数量
借助单位量词表示一定数量:a/one + 量词 + of + [un];
基数词+量词复数+of +[un].
