五，现在进行时的用法
1.表示说话时正在进行的动作
常和now连用，有时和动词如look，listen等连用，表示“现在”这一概念：

我们在找一栋房子想租一个夏天。
Are you trying to find a furnished house

表示一个在最近按计划将进行的动作或为将来安排好的活动，通常需要一个表示时间的状语：
We are spending next summer in England.
我们将要在英国度过明年夏天。
I'm getting married tomorrow.
我明天就要结婚了。
用arrive（到达），come（到来），go（走、离去），leave（离开）等动词的现在进行时描写行程安排，有“将到达”和“将离去”的意思：

明天早上他将乘7时30分的火车到达。
Christmas is coming soon.
圣诞节很快就到了。
I'm leaving England and going to live in Spain.
我将离开英国去西班牙定居。
六，现在进行时与一般现在时的区别
（一）现在进行时表示动作的暂时性，而一般现在时表示动作的习惯性和经常性
I am watching TV now. （暂时性）我现在在看电视。
I watch TV every day. （经常性） 我每天都看电视。
（二）现在进行时可表示短暂性动作，而一般现在时表示长久性动作。
Lucy is living in Beijing.（短时间居住）露西暂时住在北京。
Lucy lives in Beijing. （长久性居住） 露西在北京居住或生活。
（三）有些动词不能用进行时，know, understand, love, like, hate, wish, want, think, hope, have, believe, agree, hear, see, notice。这些动词通常用一般现在时表示说话时发生的动作。
