Question

The first few years in the 21st century ______ the rapid rise of China as a world economic power.

A．witness

B．has witnessed

C．will witness

D．have witnessed

Answer 1

B

試題分析：考查時(shí)態(tài)題。根據(jù)The first few years in the 21st century可知應(yīng)該用現(xiàn)在完成時(shí)。本句是無生命的東西作主語，此處的the past two years作主語。witness 解釋為：見證了。句意：21世紀(jì)的前幾年見證了中國做為經(jīng)濟(jì)大國的快速成長。選B。
點(diǎn)評：時(shí)態(tài)的考查主要看動詞發(fā)生的時(shí)間，如果沒有時(shí)間就看上下文，這題的解題關(guān)鍵是The first few years in the 21st century，說明是過去到現(xiàn)在一直做的事情。
