Question

4．從上個(gè)月起，那個(gè)新博物館已經(jīng)投入使用．The new museum has been in use since last month．．

Answer 1

分析 The new museum has been in use since last month．

解答 答案：The new museum has been in use since last month．
句中的投入使用come into use發(fā)生在過(guò)去，已經(jīng)持續(xù)了一段時(shí)間，用現(xiàn)在完成時(shí)have/has+過(guò)去分詞，主語(yǔ)是the new museum三單，故用has，come into use是短暫性動(dòng)詞短語(yǔ)，需換成狀態(tài)be in use，be的過(guò)去分詞been，故The new museum has been in use，時(shí)間狀語(yǔ)since last week從上月起，故答案是The new museum has been in use since last month．

點(diǎn)評(píng) 現(xiàn)在完成時(shí)表示過(guò)去發(fā)生或已經(jīng)完成的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果，或從過(guò)去已經(jīng)開(kāi)始，持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài)． 時(shí)間狀語(yǔ)：recently，lately，since…for…，in the past few years，etc．基本結(jié)構(gòu)：have/has+done  否定形式：have/has+not+done．
