what's the difference between'Did you finish your work?'&'Have you finsihed your

1) "What time is it?" or "What's the time?" (used when you are fairly certain that the person will know the time). 2) "Do you happen to have the time?" (used when you don't know whether the person has a watch or not) 3) "Do you have the time?" is EITHER a slightly more polite version of (1) OR used when you are asking someone if they can spare the time to help you with something or do something for you. The verb 'to happen to [have/know something]' is used when the possession or knowledge of something is coincidental, extra or slightly unexpected to the situation. N: "How an I going to cut this rope?" M: "I happen to have a pocket knife on me. You can use that!" N: "What is the capital of Iceland?" M: "I happen to know that because I heard it on the News the other day."

thank you!zerostats,by the way i'd like to ask you another question:if i want to know the time.i can ask'what time is it?'and i learned a sentence of 'do you happen to have the time?'is it equal to 'do you have the time?'?,if so what is the 'happen to 'used for?,many thanks

It means to have by chance or coincidence.If I pop a button off my shirt and you happen to have a safety pin,it means you did not have a safety pin because you expected me to pop a button,but it's a coincidence that I popped a button at the same time you had a safety pin. It is wordy and in good writing style,it should be avoided. In everyday use it can make a request to either loan or borrow something sound less pushy. "Do you have a pen I can borrow" is somewhat more abrupt than asking,"Do you happen to have a pen I can borrow." "Oh you popped a button! I have a safety pin you can use" is a tad more pushy than saying "I happen to have a safety pin you can use." It carries the idea that I have it but don't have it for any purpose and so it is no imposition if you use it.

thank you ,owlwings,by the way,when some people were watching a vedio on DVD and one of them left out for something but when he came back, the vedio was to the end.so how can he ask if the vedio is to the end?Is it to the end?it ended?has it ended?is it over?did it finish?has it finished?.......,please give me the correct sentence,many thanks to you

He would say "Has it finished?", "Is it over?" or "Has it ended?". If he wanted to know the ending of the story, he might ask "How did it end/finish?" or "What was the ending?"

hi,i know the tenses,but i don't know the diference in meaning of the two sentences,are the two sentence same in meaning?thank you
