药疹治疗首先要及早使用糖皮质激素。

People like to say “Thank you” when others help them or say something kind for them. It is a very good habit.

You should say “Thank you” when someone walking ahead of you keeps the door open for you, when someone says you have done your work well, or you have bought a nice thing, or your city is beautiful. We can use “Thank you” not only between friends, but also between parents and children, brothers and sisters.

“Excuse me” is another short sentence we often use. When you hear someone say so behind you, you know that somebody wants to walk pass you without touching you.  When others are talking, if you want to speak to one of them, say “Excuse me” first, and then begin talking. You should also do so when you begin to cough or make any noise before others.
