試題分析：考察時態(tài)。本題的關(guān)鍵在于句中的副詞already已經(jīng)；該副詞常常與現(xiàn)在完成時連用。該句的主語是people，故謂語動詞使用復(fù)數(shù)形式。故C正確。
點(diǎn)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。
