        1. 【題目】In the past few years, many schools________the ways of doing morning exercises.

          A.changedB.changeC.will changeD.have changed

          【答案】D

          【解析】

          句意:在過(guò)去的幾年里,很多學(xué)校已經(jīng)改變了做早操的方式。

          考查動(dòng)詞時(shí)態(tài)。changed改變,過(guò)去式;change改變;原形;will change將改變,一般將來(lái)時(shí);have changed已經(jīng)改變,現(xiàn)在完成時(shí)。根據(jù)時(shí)間狀語(yǔ)“In the past few years”可知,這里用現(xiàn)在完成時(shí),其結(jié)構(gòu)是have done的形式。故選D
