試題分析:考查時態(tài)。句意:—我后背疼!@不令人奇怪。你在電腦前面工作的時間太長了。根據(jù)句意可知你在過去一直時間一直都坐在電腦前面,對現(xiàn)在產(chǎn)生的影響就是你的后背疼痛,故使用現(xiàn)在完成時或者現(xiàn)在完成進行時。故C正確。
點評:時態(tài)題的考查關(guān)鍵是抓住句子的上下文含義和句中的時間狀語。要根據(jù)時間狀語來選擇合適的時態(tài),在平時的學(xué)習(xí)中要注意積累有關(guān)時態(tài)的用法和各種時態(tài)的特殊之處。如since, so far等經(jīng)常與現(xiàn)在完成時連用。在條件狀語從句中用一般現(xiàn)在時代替將來時等等。
