英语语法问题
The weather's often cold in the North and windy in the East.
It's often wet in the West and sometimes warm in the South.
这两句中前面都有often所以后面的名词和动词就不用加S?哪为什么sometimes要加.
The sun rises early and sets late.“The sun”是因为是第三人称单数所以后面的动名词加S

Answer 1

sometimes是一个词,本身就带S,跟OFTEN没有关系,还有,就算有OFTEN,主句是单数第三人称的话后面动词该加S还是有S,举个例子：It often rains in the West and sometimes snows in the South.
最后一句就是因为THE SUN是第三人称单数所以后面的动词要加S,跟我上面说的一个意思
