Unit 8 Safe and sound
We can put two words together to create new words. They are called compound words. We can make compound nouns in a number of ways.
noun + noun → thunderstorm, teamwork, snowball
noun + verb → earthquake, rainfall, sunrise
verb + noun → passport, playground, driveway
adjective + noun → whiteboard, software, gentleman
TIP
Sometimes we need to add a hyphen(-):
north+east → north-east
part+time → part-time

探究二 核心单词
归纳拓展
policeman 是复合名词，意为“警察”，可作为警察的统称，但一般指代男警察，“女警察”使用policewoman，其复数形式要把后面的man/woman 变复数，即policemen/
policewomen。
man/woman 作定语修饰名词，变复数时要和后面的名词一起变复数，如：men teachers 男教师们；women nurses 女护士们。
学会运用1: Tony’s father and uncle are both _______________ (policeman). They help keep the city safe.
学会表达2: 在我们医院，女医生的数量是四十。
