The water supply has been cut off temporarily because the workers ____ one of the main pipes.
A．had repairedB．have repairedC．repairedD．a(chǎn)re repairing
D
句意：“臨時切斷了水的供給，因為工人正在修理一個主管道�！盇表示“過去的過去”，一定要有一個過去的時間做對比，不能單獨使用，故不能選A；B現(xiàn)在完成時，表示“過去一個動作對現(xiàn)在的影響或過去一個動作一直持續(xù)到現(xiàn)在還有可能再繼續(xù)下去”，一定和現(xiàn)在有關(guān)；在這里，沒有表示repair的影響，也沒有表示時間的蘊含；C過去時態(tài)，單純的過去，和現(xiàn)在沒有關(guān)系，不會題意；D現(xiàn)在進行時，說話時正在進行的動作。
【考點定位】考查時態(tài)的用法。時態(tài)要注意關(guān)注語境和時態(tài)的基本用法。尤其要注意現(xiàn)在完成時和過去完成時，前者一定和現(xiàn)在有關(guān)系，后者是過去的過去，一定要有一個過去的時間作對比。
