Suzy and her mum are trying to paint a bird house. Read their conversation and pay attention to the parts in bold.
Mum: Here’s the paint. We’d better clean the bird house first.
Suzy: OK, I’ll help you.
~~~~~~~~
长难句分析：这是一个倒装句。Here 是副词，在句中作地点状语，’s 是“is”的缩写，为系动词，the paint 是句子的主语。
TIP
'd better= had better
shouldn't= should not
Mum: Now you should mix the paint well. Then put the brush /br / into the paint. You’d better not get too much paint on the brush.
Suzy: Is this OK
Mum: Yes. Move the brush up and down
slowly like me. You shouldn’t go too fast, Suzy.
Suzy: OK, Mum.
