现在难度升级英语怎么说

在中文中，可以用 "难度升级" 来表示英语学习或使用中遇到的难度提高。这个说法可能来源于游戏中常用的 "难度升级"，表示游戏难度变大。
例句：

(The difficulty of our English exam has been upgraded, so we need to study harder.)

在英文中，也可以用其他表达方式来表示难度的提高，如：
The level of difficulty has increased.
(难度增加了。)
The challenge has gotten harder.
(挑战变得更难了。)
The task has become more difficult.
(任务变得更困难了。)
