【讲·fun】
fun 作不可数名词时，意为“乐趣；快乐”。常用短语：have fun = have a good time，意为“玩得开心”。
fun 作形容词时，意为“有趣的；使人快乐的”，与 interesting 同义。
例句：Swimming is very fun.（游泳很有趣。）/ We have fun in the park.（我们在公园玩得很开心。）
【讲·welcome】
感叹词：Welcome!（欢迎！）
动词：welcome + 地点，意为“欢迎来到某地”。如：Welcome to Beijing!
形容词：You're welcome.（不客气。）
名词：a warm welcome（热烈欢迎）
【讲·goose】
复数形式为 geese（不规则变化）。
类似的不规则复数名词要特别记忆：sheep（单复数同形）、child → children等。
【讲·how many vs. how much】
疑问词 用法 后接名词 例句
How many 询问可数名词的数量 可数名词复数 How many apples do you have
How much 询问不可数名词的数量或价格 不可数名词 How much milk do you drink
【讲·名词所有格】
表示“......的”，一般在名词后加“'s”。
例句：Fu Xing's grandparents（福星的爷爷奶奶）
以-s结尾的复数名词只加“'”：my friends' schoolbags

句型一：询问单数物品
问句 答句
What's this （这是什么？） It's a/an... （它是一个……）
What's that （那是什么？） It's a/an... （它是一个……）

句型二：询问复数物品
问句 答句
