留学生在早安会上可能会说以下几种表达：

友好的问候

"嗨，早上好，新的一天，阳光始露头角，照亮你前进方向。"

"同学早上好，读书的早习能让你开阔大脑，想象力越发活跃。"

"早上好!知道你美梦还没做完，把你吵醒也别抱怨。揉揉迷茫的小眼，洗洗困倦的小脸，再吃顿美美的早饭，开始自己美好的一天。"

鼓励性的话语

"A new day begins again. Live with confidence."

"Helpless, give yourself a smile, that is a optimistic."

"Jingling, may your dream never end."

"Warm blessing, welcome the wonderful mood."

"Take the road you want to take while you are young."

"If you hold the past too tightly, how can you spare your hand to embrace the present？"

简洁的问候

"早上好!"

这些表达既体现了留学生之间的友好关系，又包含了对新一天的期待和鼓励，适合在早安会上使用。
