(Grammar) understand and categorize [cn] and [un] on their own, recognize singular and plural forms of nouns, use 'a' or 'an' correctly, and know how to use nouns before uncountable nouns to show their amounts; improve our observation and summarization skills through the activities of preparing food for a class party; enjoy learning grammar in a teamwork setting practically and enjoyably, and use what we've learned in real-life situations. We are planning a class party next week! Today, we'll be the party planners and make a shopping list for food and drinks! Brainstorm: What kind of food and drinks should we think of to make every classmate eat and drink happily? Let’s have a look at what we have! And think:What do we need to buy? Tip: To be good party planners, we should be considerate(考虑周全的). We have two boxes of food and drinks. Let’s see what’s inside. Box 1 Choose one kind different from the other three and then tell the reasons apple bread lemon pear Reason 1: The apple, pear and lemon are fruits. But bread is not fruit. Reason 2: We can say there is one apple, one pear and one lemon. But we can’t say there is one bread. Reason 1: Milk, juice and cola are drinks. But the carrot is a kind of vegetable. Reason 2: We can’t say there is one milk, one juice or one cola. But we can say there is one carrot. Box 2 Choose one kind different from the other three and then tell the reasons milk juice cola carrot [cn] refers to something we can count. For example, an apple, two pears and ten lemons. Countable nouns [cn] Uncountable nouns [un] Types of nouns Meaning [un] refers to something we cannot count. For example, we cannot say a bread. Let’s classify the food and drinks list into [cn] and [un]. Can we count them? Tip: Some nouns can both be [cn] and [un]. How many or how much do we have? apple bread lemon pear milk juice cola carrot a lemon a pear a carrot an apple a strawberry an egg an orange an onion If the countable noun begins with a consonant sound, we use “a”. singular nouns (sing.) Form 1 If the countable noun begins with a vowel sound, we use “an”. Attention “a” VS “an” an hour /aʊ/ h是辅音字母，但在hour中不发音，发元音的是o， 用an a hat /h/ h是辅音字母，在hat中发辅音，用a 判定用a或an，不看单词首字母长相是否为元辅音字母，只能听单词首字母发音是否为元辅音音素。 Attention “a” VS “an” an umbrella /ʌ/ u是元音字母，在umbrella中发音是元音， 用an a university /juː/ u是元音字母，但在university中发音是辅音， 用a 判定用a或an，不看单词首字母长相是否为元辅音字母，只能听单词首字母发音是否为元辅音音素。 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 选用“a”或者“an”填空 a an a a an a an an an a an an a an a an a lemon a pear a carrot an apple But to hold a class party, we need more of them! three lemons five pears some carrots many apples a lot of stawberries a strawberry an egg an orange an onion lots of eggs a box of oranges four kilos of onions We add “s” to most nouns. plural nouns (pl.) Form 2.1 If the noun ends with a consonant + y, we should change “y” into “ies”. 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 take 2 buses to the great supermarket to buy 3 boxes of peaches, tomatoes, potatoes to make special dishes with the help of knives. We should add “es” after the nouns ending with “s”, “sh”, “ch” or “x”. plural nouns (pl.) Form 2.2 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. (常见还有hero). 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? a man two men a woman two women a tooth three teeth a foot feet Some special plural nouns 改变单数名词中的 元音字母 a sheep three sheep a deer two deer a fish two fish a Chinese/Japanese two Chinese/Japanese Some special plural nouns 单复同形 a mouse three mice a child four children Some special plural nouns 其他不规则变化 Some special plural nouns Form 2.3 不规则变化 改变单数名词中的元音字母 读音改变 man-men woman-women tooth-teeth foot-feet 单复数形式相同 读音不变 sheep-sheep deer-deer fish-fish Chinese -Chinese Japanese -Japanese 其他形式 读音改变 mouse-mice child-children Attention 国家人民单复数 记住口诀： 中日不变英法变，其余s加后面。 中日不变：a Chinese---many Chinese a Japanese---many Japanese 英法变：an Englishman---many Englishmen a Frenchman---many Frenchmen 其余s加后面：a German --- many Germans an American --- many Americans… 复合名词单复数变化 a paper rose two paper roses an apple tree two apple trees a boy student two boy students 大部分复合名 词变复数时，只需把后面的名词变成复数形式。 Attention two women teachers 复合名词单复数变化 复合名词为man/woman + n.时, 变复数形式：men/women + n.复数。 Attention a man doctor two men doctors a woman teacher [cn] We can use numbers or the article(a/an) with countable nouns.
