Answer 1

B

試題分析：考察名詞性從句。本題第一空使用that引導同位語從句that they had died from diseases such as bird flu解釋前面的名詞sign的內(nèi)容。第二空that引導的是一個主語從句that a truck had collided（碰撞）with the crowd, that在句中不充當任何成分，只起引導和連接的作用。句意：沒有他們死于禽流感的跡象，禽流感是這個地區(qū)的最主要擔心的死亡的原因。在這些原因里，一輛卡車撞上了人群。故B正確。
點評：名詞性從句要使用陳述語序。同時考查集中在引導詞的選擇上，連接詞that, whether, if在句中不充當任何成分，只起連接作用；連接代詞who(ever), which(ever), whom(ever),whose(ever),what(ever)在句中做主語，賓語，表語和定語；連接副詞when, why, where, how，在句中做狀語。應(yīng)從上下句的句法關(guān)系著手分析，切不可‘望句形生答案’總的來說，考生在解答此類題型時，可用排除法，造句法或者還原法，造句法就是仿造原句的語法功能仿造出一個易懂易理解的句子，幫助判斷。
