Lesson 4
Unit 1
Spring is coming!
1 Read the questions and give your answers.
A What special days do you like in spring
B When can you see flowers bloom in your city (答案均不唯一)
I like Tomb-sweeping Day in spring. It’s a time to remember
ancestors and enjoy nature.
In my city, I can see flowers bloom in March and April.
2 Read the email from Jenny and answer the questions.
Dear Wang Mei,
It isn’t snowing today, but there is still snow on the grass. In Edmonton, the weather in spring is a little wild. It can be cold and snowy or warm and sunny. The temperature can be as low as -15℃ , but it can also reach 15℃ . We probably won’t see any flowers until May or June!
After school today, we had so much fun playing outside. We played “snow” soccer, but we had to wear jackets, jeans, and boots to stay warm. When it gets warmer, we can play in our shorts and T-shirts.
I like spring because there are lots of activities to do, like cycling, having picnics, and hiking.
作目的状语
prep. 穿着；戴着
长难句分析：这是一个复合句。I like spring 是主句，because there are lots of activities to do 是由because 引导的原因状语从句。从句there are lots of activities to do 是there be 句型，to do 作后置定语修饰activities；like cycling, having picnics, and hiking 是用于举例说明春天可进行的具体活动。
I like the Chinese name for winter jasmine. It’s interesting. Here, we have Groundhog Day on February 2 for the coming of spring. Do you know what happens on that day
Another fun part of spring is going to the sugar bush, a big tree farm in the countryside. We make maple syrup. We eat lots of tasty breakfast foods—all with maple syrup on them! I love spring activities.
Talk to you soon!
Jenny
adv. 作地点状语
长难句分析：这是一个简单句。Another fun part of spring作主语，系动词是is，going to the sugar bush是动名词短语作表语，a big tree farm in the countryside作 the sugar bush的同位语。
Groundhog Day is on February 2. On that day, a small animal called groundhog comes out of its hole in the ground.
A Jenny says the weather in spring is a little wild. What does she mean
She means the spring weather in Edmonton is changeable. It can be cold and snowy or warm and sunny, and the temperature varies greatly (from -15℃ to 15℃) .
B Where does maple syrup come from
Maple syrup comes from maple trees. People get it from big maple tree farms in the countryside.
