用more than造句

问题描述:

用more than造句
我第一个
trying to fly on weekend is always more than expensive in a week.
我的句子有错误么
应该怎么造呢

你要表达的意思很清楚:在周末乘机度假通常是一周中最昂贵的.
这种句子涉及到形容词的*的问题.正确形式:
Trying to fly on weekend is always the most expensive in a week.
如果要用“more than”,正确形式:
Fly on weekend is always more expensive than on weekdays.
