选serious.这辆车的司机收了很严重的伤.
被修饰词是injuries,名词,所以用形容词serious来修饰.如果这句话这么来说：the driver of the car had been （）injured.这里就要用seriously,injure这里是谓语动词,虽然用了被动语态,但仍然要用副词seriously来修饰.there was a( )change in the weather.[sudden/suddenly]选sudden，因为被修饰词是名词change。天气有了突然的变化，也就是天气突然有变。记住，形容词修饰名词，副词修饰动词。先弄清楚了这个选项词是用来修饰什么词的，就好选了
