句子：今年极端天气发生得比往年频繁。

误译： Extreme weather has occurred more frequent this year than previous years.

正译：Extreme weather has occurred more often/frequently this year than previous years.

解释：frequent 是形容词，不能修饰动词。需要用表示时间频度的副词often 或frequently修饰动词occur。

“极端”的第二个意思是“偏激”、“绝对”或“彻头彻尾”，是形容词，译为 extreme。例如：2. 自学能力对一个学生极端重要。Self-taught ability is of extreme importance to a student.

“极端”的第三个意思是表示程度极深,相当于“极其”或“非常”，是副词，译为extremely, exceedingly。例如：3. 这位经济分析师认为试图救助楼市是极端愚蠢的行为。The economic analyst holds that trying to save the real estate market is an exceedingly foolish act.

“极端”的第四个意思是“极其不正常”，是形容词，译为 extreme。例如：4. 我国许多地方最近经历了极端天气状况，包括热浪、暴风雨和洪水。Many places of our country have recently experienced extreme weather conditions including heatwaves, storms and floods.▲
