under

［析］ 這句話的意思是"我想讓別人理解我太難了"。

［正］ i waited for my mother until seven o'clock, but she didn't come.
［誤］ can you return this book until monday?

［正］ we didn't arrived home until it became dark.
［析］ until用于肯定句時表示"某動作直到……為止"，如： they worked until 5∶00 p. m. 用于否定句中時意為"直到……才"。所以用于肯定句中要使用延續性動詞，但截止性動詞卻可以用在否定句中。
upstairs

［析］ upstairs一詞可用作副詞，如： we all hurried upstairs to see what happened. 也可用作名詞，如； the upstairs of the house needs painting. 同時也可以用作形容詞，如： a house with three upstairs rooms is quite good.
