        1. In recent years, the economy of our country _________ rapidly.
          A.is increasedB.has increasedC.increasedD.has been increased
          B

          試題分析:句意:近些年,我們國(guó)家的經(jīng)濟(jì)有了飛速的發(fā)展。句中有In recent years近些年,謂語動(dòng)詞用現(xiàn)在完成時(shí)的形式,不需要用被動(dòng)形式,故選B
          點(diǎn)評(píng):動(dòng)詞的時(shí)態(tài)是學(xué)習(xí)英語過程中非常重要的知識(shí),F(xiàn)在完成時(shí)表示動(dòng)詞在過去發(fā)生對(duì)現(xiàn)在造成的影響。現(xiàn)在完成時(shí)往往和already,yet,for+一段時(shí)間,since+點(diǎn)時(shí)間的時(shí)間狀語連用。一般過去時(shí)只表動(dòng)詞在過去發(fā)生,一般現(xiàn)在時(shí)表示習(xí)慣性的動(dòng)詞或是客觀真理、事實(shí)。
