Steve,have you decided yet which book to write about for English class
which book to write about是“疑问词+不定式”结构。在从句中,从句含有疑问代词(副词)引导的从句可替换为“疑问代词(副词)+不定式结构”,此结构常放在tell, show, teach, learn, know, wonder, forget,decide等动词之后作宾语。
例句：你能教我怎样骑马吗？
Can you teach me how to ride a horse
例句：我不知道该在哪下车。
I don't know where to get off.
It was really good, so I couldn’t put it down.
put down放下
can't put sth. down意为“对某物爱不释手”。
put... down 为“动词＋副词”型短语，宾语若为代词，应放在put 与 down 中间。
put down还意为“写下，记下”，等于write down。
例句：你们不要举手，请放下。
Don't put up your hands. Please put them down.
例句：它是一本有趣的书，他对它爱不释手。
It is an interesting book and he can't put it down.
put 短语

put on 上演；穿上
put off 推迟
put away 放好；收拾
put in 插话
put up with 忍受；容忍
put out 熄灭
You should hurry up. The book report is due in two weeks.
hurry作动词，可表示“赶快；匆忙”。其中hurry up在口语中常用来表示催促，意为赶快；急忙（做某事）【搭配】in a hurry匆忙地, hurry off匆忙离开, hurry away匆匆离去。
due为形容词，意思是“预定；预期的；预计”。后面引出预期的时间、地点等，还常构成短语be due (to do sth.)或be due (for sth.)。
例句：她的宝宝预计在下个月出生。
Her baby is due next month.
例句：快点吧，要不然你今天准会迟到。
You must hurry up, or you'll be late today.
