【1】melting ice=ice that is melting指正在融化的冰；备注：现在分词作前置定语，相当于现在进行时态定语从句作后置定语。【2】melted ice=ice that has melted指已经融化的冰备注:不及物动词过去分词作前置定语，只表示完成，不表示被动，所以相当于现在完成时态定语从句作后置定语。

Next week, Tom's family______to China, so they are now getting ready for it. 横线填A. is going to travel还是B. are travelling？备注：以上只能选B答案,因为后面主语用了第三人称复数人称代词they(他们)，they指代复数名词，所以这里family只能理解“家人”不能理解为“整体概念家庭”Next Week, Tom’s family are travelling to China, so they are now getting ready for it.下个周汤姆的一家人打算要去中国旅行，所以他们现在正在为此做准备。备注: they指代Tom’s family(汤姆的家人)
