{{Grammar Box}} 在 (zài) and 正在 (zhèngzài) can be used as [[auxiliary verb|auxiliary verbs]] to express that an action is ''ongoing'' or ''in progress''. This is often the equivalent of ''present continuous'' in English, which is how we express that an activity is happening ''now''. You can use 正在 (zhèngzài) instead of just 在 (zài) to put a little more emphasis on an action that is ''in progress '''right now'''''. == Structure ==

There is no need to worry too much about when to use 在 (zài) or 正在 (zhèngzài), since they basically mean the same thing. 正在 (zhèngzài) usually shows that the action is in progress (''right now''). "在 (zài) + Verb" is more commonly used than "正在 (zhèngzài) + Verb," but both are fine to use. == See Also == *[[Aspect particle "zhe"]] *[[Expressing actions in progress (full form)]] (more advanced usage) == Sources and further reading == === Books === * [[Basic Patterns of Chinese Grammar]] (pp. 41-2) [http://www.amazon.com/gp/product/1933330899/ref=as_li_ss_tl?ie=UTF8&tag=allset-20&linkCode=as2&camp=217145&creative=399373&creativeASIN=1933330899 →buy] * [[Chinese: An Essential Grammar, Second Edition]] (pp. 60-1) [http://www.amazon.com/gp/product/0415372615/ref=as_li_ss_tl?ie=UTF8&tag=allset-20&linkCode=as2&camp=217145&creative=399369&creativeASIN=0415372615 →buy] * [[Integrated Chinese: Level 1, Part 1 (3rd ed)]] (pp. 209-10) [http://www.amazon.com/gp/product/0887276385/ref=as_li_ss_tl?ie=UTF8&tag=allset-20&linkCode=as2&camp=217145&creative=399369&creativeASIN=0887276385 →buy] * [[New Practical Chinese Reader 2 (新实用汉语课本2)]] (pp. 218-9) [http://www.amazon.com/gp/product/7561911297/ref=as_li_ss_tl?ie=UTF8&tag=allset-20&linkCode=as2&camp=217145&creative=399369&creativeASIN=7561911297 →buy] [[Category:A2 grammar points]] {{Used for|Referring to the present }} {{Used for|Indicating conditions}} {{Used for|Describing actions}} {{Basic Grammar|在|A2|(正)在 + Verb|我们 正在 吃饭。|grammar point|ASG846EA}} {{Rel char|正在}} {{Rel char|正}} {{Similar|Aspect particle "zhe"}} {{Similar|Expressing actions in progress (full form)}} {{POS|Adverbs}}
