现在进行时
一、概念
表示说话时正在进行或发生的动作,也可表示当前一段时间内的活动或现阶段正在进行的动作.结构: be 动词( am / is / are ) +现在分词. 二、 现在分词的构成
1.大多数动词后可在动词后直接加-ing,如: carry-carrying,catch-catching,drink-drinking, enjoy-enjoying
2.如果动词以-e结尾,则去掉-e,再加-ing,如:come-coming , have-having , make-making,ride-riding
3. 如果动词只有一个元音字母,而其后跟有一个辅音字母时,将此辅音字母双写,再加-ing(但是open却不属于这规则,而是直接加ing
open-opening)hit-hitting,let-letting,put-putting,run-running 4. 以 -ic 结尾的动词,应先把 -ic 变为 -ick,再加 -ing,eg:
panic/panicking,picnic/picnicking,但lie/lying ,die/dying,tie/tying是特殊变化
注: 不是所有动词都能用现在进行时态的,如see、like、want、know 等动词往往都不用进行时态. 三.用法
1.表示现在( 指说话人说话时) 正在发生的事情.往往与 now,at the moment,just 等副词连用,以示强调.
如:We are waiting for you. What are you doing? Some one’s knocking at the door.
2.正在进行着的动作可视为未完成的动作:
如:He’s talking to his friends in the classroom. 3. 表示长期的或重复性的动作,说话时动作未必正在进行. Mr. Black is writing another article. 4.现在进行时也可以用来表示当前的动向:
People are becoming more and more beautiful these days. 5. 表示渐变的动词有:become,turn,get,grow,run,go,begin等. The leaves are turning brown.It’s getting colder and colder.
6. 现在进行时(以及 be going to)可以表示为将来安排好的活动和事件 We’re spending next winter in China. 用arrive,come,go,leave 等动词的现在进行时描写行 程安排,也通常有“将到达”和“将离去”的意思: He’s arriving tomorrow morning.
7.当现在进行时表示某事发生的次数过多时,则有时含有抱怨,讨厌,赞扬等的意思:
He isalways singing at night,and we can’t fall asleep late at night. 练习
