slow(ly)
1.slow后面接不定式是“不愿…的”或“不大会得…的”。例如：He is not slow to defend himself. 和She is slow to take offence. slow后面接in和动名词是“…得太迟的”或“…得慢的”。例如：The guests are slow in arriving. 和The crowd is slow in breaking up.
2.slow用作副词不及slowly普通。但在着重“慢”或“细心”的意思的场合往往用slow而不用slowly，在口语里更多用slow。例如：
- How slow the time passes!
I saw some boys pass slowly by. - Please read as slow as you can.
He used to spend his evenings reading slowly
3.下面每组里的两句意思相同，但第一句比第二句普通：
- The car is slowing down.
The car is slowing up. - You had better slow down your car.
You had better slow up your car.
