----the boys likes pop music very much. 没有上下文1和2 都是对的,either of和neither of 作主语谓语动词用单数, both of 作主语谓语动词用复数,而like后面加s了所以不行. -1.either of---the boys likes pop ...额，我填的是either of，但答案是neither of ，搞不明白，才来问。 there are trees on_____side of the street. 答案是either ,我填的是both ,这一题呢。能不能跟我讲讲？谢谢there are trees on_____side of the street. 答案是eithereither后面加可数名词单数 both后面加可数名词复数，而side没加s所以不行，但如果加了s就可以了
