In English, we might say I am traveling from the U.S. to China or I’ll be on vacation from May to June. To say the same thing in Chinese, use 从 (cóng, from) and 到 (dào, to).
从美国到中国
cóng Měiguó dào Zhōngguó
from the U.S. to China
从五月到六月
cóng Wǔyuè dào Liùyuè
from May to June
从九点到五点
cóng jiú diǎn dào wú diǎn
from 9 o’clock to 5 o’clock
You already know that 上 (shàng) can mean last (as in 上星期) and that 下 (xià) can mean next (as in 下个周末).
We can also use 上 for go to, and 下 for get off (as in to get off work).
我们上午九点上班。
Wǒmen shàngwǔ jiǔ diǎn shàngbān.
We go to work at 9 in the morning.
你明天几点下班？
Nǐ míngtiān jǐ diǎn xiàbān?
What time do you get off work tomorrow?
我的妹妹十一点上学。
Wǒ de mèimei shíyī diǎn shàngxué.
