动词变正在进行词规则帮
现在进行时表示现在正在进行或发生的动作
规则：
1.一般在动词原形末尾加ing
2. 以不发音字母e结尾的动词,去e,再加ing
3. 以重读闭音节结尾的动词,如果末尾只有一个辅音字母,应先双选这个字母,再加ing
4.还有几个特殊的.
现在进行时的形式
现在进行时由 be 的现在式 + 现在分词构成.
I am You are He is She is It is We are You are They are
缩写形式如下 I'm You're He's She's It's We're You're They're
拼写法：动词后面如何加 -ing wait/waitng
大多数动词后可直接加-ing,而不需改变动词的拼写法.
如beat/beating, carry/carrying, catch/catching, drink/drinking, enjoy/enjoying, hurry/hurrying.
如果动词以-e结尾,则去掉-e,再加-ing,如 come/coming, have/having, make/making, ride/riding, use/using.但以-ee 结尾的动词和age,singe两个动词除外：agree/agreeing, see/seeing, age/ageing, singe/singeing. run/running
如果动词只有一个元音字母,而其后跟有一个辅音字母时, 则将此辅音字母双写,再加-ing,如：hit/hitting, let/letting, put/putting, run/running, sit/sitting. begin/beginning
如果动词有两个音节,且重音在第二个音节上,则末尾的 辅音字母须双写,再加-ing,如 for'get/forgetting, pre'fer/ preferring, up'set/upsetting.
试比较 'benefit/benfiting, 'differ/differing, 'profit/profiting, 这些词的重音在第一个 音节上,因此其末尾的辅音字母不双写.注意在英国英语中 'label/labelling, 'quarrel/quarrelling, 'signa/signalling, 'travel/travelling等例外情况,但在美国英语中则不双写,如 labeling, quarreling, signaling, traveling.
以 -ic 结尾的动词,应先把 -ic 变为 -ick,再加 -ing,
如 panic/panicking, picnic/picnicking, traffic/ frafficking. lie/lying 其他如 die/dying, tie/tying均同此.
现在进行时的用法
说话时正在进行的动作 现在进行时表示说话时正在进行的动作或事件.
往往与 now, at the moment, just 等副词连用,以示强调： Someone's knocking at the door. Can you answer it? What are you doing? I'm just tying up my shoelaces. He's working at the moment, so he can't come to the telephone.
正在进行着的动作皆被视为未完成的动作： He's talking to his girlfriend on the phone.
可用 still 一词强调动作的持续性 He's still talking to his girlfriend on the phone.
暂时情况 现在进行时可用来表示不会长期发生的动作或情况,或 被认为在短期内正在进行的动作或存在的情况：
What's your daughter doing these days? She's studing English at Durham University.
这种情况不一定在说话时发生： DOn't take that ladder away. Your father's using it.
（他父亲现在不一定在用） She's at her best when she's making big decisions.
暂时发生的事情也可以是在说话时正在进行着： The river is flowing very fast after last night's rain.
现在进行时也可以用来表示当前的动向： People are becoming less tolerant of smoking these days.
事先计划好的动作：指将来 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；除在上下文中意思清楚者外,通常需要 一个表示时间的状语： We're spending next winter in Australia. 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 on the 13:27 train.
用现在进行时表示说话时正在进行的动作时,可用状语 和上下文使语义不致含混： Look! The train's leaving. （即火车实际上正在开动.）
重复的动作 副词 always（表示“屡次”）,constantly, continually, forever, perpetually, repeatedly 等等可与进行时连用,表示 不断重复的动作： She's always helping people. 某些状态动词带有 always 等词亦可用进行时： I'm always hearing strange stories about him.
当现在进行时表示某事发生的次数过多时,则有时含有 抱怨的意思： Our burglar alarm is forever going off for no reason.
