I expect____(finish)the work by the end of next week I have something important____(tell)you

【專家解說】：現(xiàn)在理解你后面為什么提那個完成時的問題了： i expect to have finished=i expect that i will have finished將來完成時，用不定式替換了，強(qiáng)調(diào)“希望將來某一個時間之前（能夠）完成”，不定式本身就可以有將來的蘊(yùn)涵，所以后面一個用不定式to tell作為后置定語修飾something，“將來（在說話時間之后）告訴你”。
