Question

12．到目前為止，我已經(jīng)用多種方法成功地算出那道數(shù)學題．I have successfully worked out/solved that maths problem in many ways so far．．

Answer 1

分析 I have successfully worked out/solved that maths problem in many ways so far．

解答 答案：I have successfully worked out/solved that maths problem in many ways so far．這里的時間狀語到目前為止so far與現(xiàn)在完成時連用have/has+過去分詞，主語是I，故用have，算出用work out或者solve，故I have worked out/solved后直接加上賓語that math problem，加上副詞 successfully 修飾worked out/solved，故I have successfully worked out/solved that maths problem，用多種方法用in many ways，故答案是I have successfully worked out/solved that maths problem in many ways so far．

點評 這里是現(xiàn)在完成時，它的時間狀語有如since…，
for…； ever，never，recently（最近），today，this week （year），these days （weeks，years），in/during the last/past two years，so far等．
