The lifestyle we were used to ________ a lot these years.
A．changingB．changedC．has changedD．being changed
C

試題分析：這些年,我們已經(jīng)習慣了的生活方式改變了很多.結(jié)合語境可知本句描述的是現(xiàn)在已經(jīng)完成的動作,故用現(xiàn)在完成時態(tài).選C.
點評：英語中的時態(tài)主要是借助于時間狀語與上下文語境來進行判斷。解答此類題型，首先要注意句子中的時間狀語，如果沒有則要通過分析上下文，結(jié)合語境來判斷句子的時態(tài)。英語疑問句中一般具有時態(tài)上的對應(yīng)關(guān)系，注意結(jié)合這一特點進行區(qū)分。
