time: during, over, for, by, until. Exercise instructions: Choose the correct preposition in the following sentences. 1. He planned to stay here (for) two weeks but they need him back at work immediately. 2. Could you deliver the new computer monitors (until) the end of next week? We need them before next Friday at the latest. 3. I waited for her call (until) 6 p.m. but she didn't call. I suppose she was busy. 4. No one was allowed to use any written materials (during) the exam. 5. I hope he hasn't had an accident. He said he would be here (until) six but he hasn't come yet. little difference between 'by' and 'until' is that the preposition 'by' means that someone do some new work within the time limit which speaker make. And 'until' means someone have to do something continously withibn the time limit. Is my understanding correct?

Hi there, Jo! Thank you for your composition! I\'d like to share some tips with you regarding the difference between by and until. Both until and by indicate \"any time before, but not later than.\" Until tells us how long a situation continues. If something happens until a particular time, you stop doing it at that time. For example: They lived in a small house until September 2003. (They stopped living there in September.)We also use until in negative sentences. For example: Details will not be available until January. (January is the earliest you can expect to receive the details.) On the other hand, if something happens by a particular time, it happens at or before that time. By is often used to indicate a deadline. For example: You have to finish by August 31. (August 31 is the last day you can finish; you may finish before this date.) We also use by when asking questions. For example: Will the details be available by December? (This asks if they will be ready no later than December.) T. JanE ^^ time: during, over, for, by, until.Exercise instructions:Choose the correct preposition in the following sentences.1.
