試題分析：考查詞組和主謂一致。A. work on從事，忙于，B. works at致力于，因?yàn)橹髡Z(yǔ)由along with,連接時(shí)，其謂語(yǔ)動(dòng)詞的單復(fù)數(shù)形式通常由前面的詞來(lái)決定。就是Professor Smith故用單數(shù)謂語(yǔ)，在BC里面選擇，句意：為了如期完成，斯密斯教授和他的助手日夜忙著這個(gè)項(xiàng)目。答案為C項(xiàng)。
點(diǎn)評(píng)：主語(yǔ)由as well as, along with, together with, rather than, no less than, but, except, besides, in addition to, like, including等詞連接時(shí)，其謂語(yǔ)動(dòng)詞的單復(fù)數(shù)形式通常由前面的詞來(lái)決定。這題還考查了work相關(guān)的短語(yǔ)，做題目要綜合考慮。
