导入新课
Lead-in
Show the pictures and introduce the target words
T: Boys and girls. Let’s look at this picture. These boys like playing basketball. They are active in doing sports, but they are not active in study. Here “not active”, we can also say “inactive”.
T: Look,she is happy but he is not happy, or we can say unhappy.
T: I will finish my homework as much as possible. But it’s not possible for me to finish all of it. We can use “impossible” to replace “not possible”.
T: Millie’s mom is on business. Look her bedroom is not tidy. Can you help her make the room tidy? So we can use “untidy” to replace “not tidy”.
