By the first day of August, 2007, the PLA ________ for eighty years.

A．founded                              B．has founded

C．has been found                         D．had been founded

 

【答案】

D

【解析】

試題分析：句意：到2007年八月的第一天，中國(guó)人民解放軍已經(jīng)建立了八十年了。結(jié)合語(yǔ)境可知本句描述的是過去某時(shí)之前已經(jīng)完成的動(dòng)作，故用過去完成時(shí)態(tài)。主語(yǔ)是被建立的對(duì)象，故用被動(dòng)語(yǔ)態(tài)，選D。

考點(diǎn)：時(shí)態(tài)及語(yǔ)態(tài)

點(diǎn)評(píng)：英語(yǔ)中的時(shí)態(tài)主要是借助于時(shí)間狀語(yǔ)與上下文語(yǔ)境來進(jìn)行判斷。解答此類題型，首先要注意句子中的時(shí)間狀語(yǔ)，如果沒有則要通過分析上下文，結(jié)合語(yǔ)境來判斷句子的時(shí)態(tài)。語(yǔ)態(tài)的判斷主要是確定句子主語(yǔ)與謂語(yǔ)動(dòng)詞的關(guān)系。如果是主動(dòng)關(guān)系則用主動(dòng)語(yǔ)態(tài)，反之如果是動(dòng)賓關(guān)系，則用被動(dòng)語(yǔ)態(tài)，尤其要注意一些特殊動(dòng)詞的用法。

    Long, long ago people made fires from lightening (閃電). But they had to keep the fire burning, for they couldn't start it again if there was no lightening. Later, they found out hitting two pieces of stone together could make a spark (火花). The spark could fire dry leaves. In this way they could make the fire again if it went out. Then people also learned to make a fire by rubbing (摩擦). They made a hole in a piece of wood and put a smaller stick into the hole. They turned the stick again and again. After a few minutes they got a fire.
