C．have finished; are working	D．have finished; work

Answer 1

A

試題分析：考查時態(tài)，第一空時間是By the end of last month，by+過去時間，要和過去完成時連用，第二空時間是now，用現(xiàn)在進(jìn)行時，句意：--他們的計劃完成了嗎？--是，到上個月底為止，他們已經(jīng)完成了�，F(xiàn)在正從事新的計劃。選A。
點評：試題的考查要根據(jù)上下文的語境和句子中的關(guān)鍵詞。本題就是根據(jù)上下文的語境來進(jìn)行辨析的。這道題目有明顯的時間，就比較好做。
