B

試題分析:句意:你的叔叔在哪兒?——他已經(jīng)出差去了南非。他已經(jīng)去過(guò)那兒兩次了。在完成時(shí)態(tài)中has been to 是已經(jīng)去過(guò)某處,并且已經(jīng)回來(lái)了。has gone to 是已經(jīng)去了某處,但是到目前為止還沒(méi)有回來(lái)。 has been in 是已經(jīng)在某處,并且現(xiàn)在還在那里,而且有可能要延續(xù)下去。 結(jié)合語(yǔ)境可知選B。
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(lái)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(méi)有則要通過(guò)分析上下文,結(jié)合語(yǔ)境來(lái)判斷句子的時(shí)態(tài)。完成時(shí)態(tài)中的動(dòng)詞有瞬間動(dòng)詞和持續(xù)性動(dòng)詞之分,瞬間動(dòng)詞的過(guò)去分詞強(qiáng)調(diào)的是動(dòng)作的完成,持續(xù)性動(dòng)詞強(qiáng)調(diào)的是動(dòng)作的持續(xù)性,F(xiàn)在完成時(shí)態(tài)中表示一段時(shí)間的時(shí)間狀語(yǔ)不能和瞬間動(dòng)詞連用,持續(xù)性動(dòng)詞不能和表示瞬間時(shí)間的時(shí)間狀語(yǔ)連用,需注意區(qū)分。
