Question

----Tony, why are your eyes red?
---I __ up peppers for the last five minutes.

A．cut

B． was cutting

C． had cut

D．have been cutting

Answer 1

D

試題分析：由for the last five minutes時(shí)間狀語可分析出該動(dòng)作由過去發(fā)生一直延續(xù)到現(xiàn)在（可能到將來），因此要用現(xiàn)在完成進(jìn)行時(shí)來表示。故D選項(xiàng)正確。句意為“ Tony,你眼睛為什么是紅的？”“ 那是近五分鐘以來我一直在切辣椒�！�
【知識拓展】各時(shí)態(tài)的區(qū)別：
一般過去時(shí)，純粹講述過去發(fā)生的動(dòng)作或狀態(tài)，跟現(xiàn)在沒關(guān)聯(lián)，通常都要有表示過去的時(shí)間狀語。如：The engine stopped because the fuel was used up.
②過去進(jìn)行時(shí)，表示在過去某一時(shí)刻正在發(fā)生的動(dòng)作或該動(dòng)作與過去的另一動(dòng)作同時(shí)發(fā)生或表示過去一段時(shí)間內(nèi)正在進(jìn)行的動(dòng)作等。如：He was watching TV at home from 3:00 to 5:00 yesterday afternoon.。
③過去完成時(shí)，表示某一動(dòng)作或狀態(tài)在過去某一時(shí)間之前或過去某一動(dòng)作之前已經(jīng)完成。句中常用by引導(dǎo)的時(shí)間狀語或以 before, until, when, than等詞引導(dǎo)的內(nèi)含一般過去時(shí)的時(shí)間狀語從句；或表示一個(gè)動(dòng)作或狀態(tài)在過去某一時(shí)刻之前就已開始，一直持續(xù)到這一過去時(shí)間，還可能再持續(xù)下去（但跟現(xiàn)在沒聯(lián)系）。如：John and Jane had known each other for a long time before their marriage.
