Question

【題目】“______ your best? It’s not satisfactory. I’m afraid you will have to do it again.” ( )

A.Do you tryB.Have you triedC.Are you tryingD.Have you been trying

Answer 1

【答案】B

【解析】

句意：你盡力了嗎？這不令人滿意。恐怕你不得不這么做。這句話應(yīng)該問的是在現(xiàn)在的過去，你是否盡力了，所以用現(xiàn)在完成時(shí)，現(xiàn)在完成時(shí)更加突出，強(qiáng)調(diào)時(shí)間對(duì)比，從過去到現(xiàn)在的這個(gè)努力程度。故選B。
