(explain)haveunderstood(understand)Are...listening(listen)hadworked(work)earned(earn)had...earned(earn)wasn'tlistening(notlisten)說明:sofar表明要用完成時,但是inthattime表明這個例子說的是過去的事情。所以應該從過去時(一般式、完成式)考慮。

上面提供的答案有點問題。"I have explained(explain)this to you several times already。"said the teacher。"I hope you understand (understand)it now。"Then he looked at a little boy at the back of the class。" Are you listening(listen),Jones?"he asked。"Here is a simple problem:"Sally has been working (work)in an office for thirty-four weeks。In that time,she earned(earn)￡300 a week。How much has she earned (earn)so far?""Please,sir,"Jones answered,"I can only answer your first question。I was not listening (not listen)。"1。我認為understand在這里只是在說明一種事實，即”明白了“，不應該用完成事態。2。work這個動作應該現在仍在延續（從so far推斷），所以應用現在完成進行時has been working;3。我的答案中最后一個listen有誤，前面幾位很正確，應該是was not listening,(當時沒有在聽,而不是現在)。
