同学你好~
是to be asleep哦
asleep是形容词，意思是“睡着的”
She was still half asleep when she arrived at work.
她到了上班地点时仍然睡眼惺忪。
My four year-old daughter was asleep on the sofa.
我4岁的女儿在沙发上睡着了。

pretend后面要加to do形式的动词，比如
The children pretend to be different animals dancing to the music.
孩子们扮成不同的动物，随着音乐起舞。

因为asleep是形容词，所以和be动词搭配。pretend to be asleep 装睡
Sometimes the boy pretended to be asleep.
有时这个男孩会假装睡着了。

祝同学学习进步~
