难到我们用英文怎么说

在英语中，"难"通常用单词 "difficult" 来表示。

"Difficult" 来自拉丁语 "difficips"，意思是"困难的"、"费力的"。

例句：

The math problem was too difficult for me to solve. (这道数学题太难了，我解不出来。)
Learning a new language is always difficult at first. (学习一门新语言总是很困难的。)
It was difficult for the team to win the game, but they eventually succeeded. (这支队伍赢得很难，但最终他们成功了。)

注意：在英语中，"难"还可以用形容词 "hard" 来表示。"Hard" 在口语中更常用，意思与 "difficult" 相同。例如：

The test was really hard. (这场考试真的很难。)
It's hard to learn a new skill when you're older. (当你年纪大了之后，学习新技能就很难了。)
