现在进行时。
一．基本用法。
表示说话时正在进行的动作，常与now, at the moment等时间状语连用，有时，句首有look，listen等词提示。例如：
what are you doing now?—i am cleaning the the students are h**ing an english lesson.
表示现阶段正在进行的动作，常与now, these days等时间状语连用。例如： is now living in australia.
目前他正住在澳大利亚。（暂时）。比较：
in australia.他定居在澳大利亚。
am working in a computer company right now.
how are you getting along these days?这些天来你好吗？
有时，现在进行时可以表示按计划安排将要发生的动作，特别是使用表示位置转移的动词时，如go, come, le**e, start, arrive等。例如：we are going to rome next week.
下周我们准备去罗马。when are you starting?你什么时候动身？
二．动词的现在分词的构成：
其动词结构为：be + doing（动词的现在分词）
1一般情况动词后加ing ,以不发音的e结尾的去e加ing。write-play-eat-see-2以重读闭音节结尾的词，双写最后的辅音字母再加ing
这样的词往往看最后三个字母，常常是“辅音＋元音＋辅音”open就不行，它的重音不在pen上。
sit-get-begin-stop-shop-swim-run-
