Hi .I'm from Argentina and Ineed a lot of help, because my english is realu awful, the worst part is that for me is really complicated talk english, What can I do for improve my speak in english?

[Torsten]

[HamburgEnglish]

Or if you ask Mister Micawber he would say

Did you order the stationery yet?
Did she order the stationery yet?

(north American)

Rob the TOEIC guy at onlineenglish.de (smile)

[Yankee]

.
Although I might say it that way too, Rob, I think it's worth mentioning that we North Americans use both versions:

Did you order the stationery yet?/Have you ordered the stationery yet?
Did she order the stationery yet?/Has she ordered the stationery yet?

Note to the founders of this forum:

Please note that I have commented on North American usage in general since I am most familiar with the usage in various areas of North America. :wink:
