分析 自從我開(kāi)始學(xué)習(xí)這門(mén)語(yǔ)言以來(lái),我已經(jīng)學(xué)了大約1600個(gè)英語(yǔ)單詞.
解答 答案:D
根據(jù)since we began to learn the language,可知應(yīng)該用現(xiàn)在完成時(shí)態(tài).since we began to learn the language是現(xiàn)在完成時(shí)的標(biāo)志詞.現(xiàn)在完成時(shí)態(tài)表示過(guò)去發(fā)生或已經(jīng)完成的動(dòng)作對(duì)現(xiàn)在造成的影響或結(jié)果.或從過(guò)去已經(jīng)開(kāi)始,持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài).本題屬于從過(guò)去已經(jīng)開(kāi)始,持續(xù)到現(xiàn)在的動(dòng)作或狀態(tài),現(xiàn)在完成時(shí)態(tài)的構(gòu)成:助動(dòng)詞have/has+過(guò)去分詞,故選:D.
點(diǎn)評(píng) 本題主要考查動(dòng)詞時(shí)態(tài),做此類(lèi)題目要注意時(shí)間狀語(yǔ)、標(biāo)志詞.根據(jù)上下文所表達(dá)的含義,做出判斷.同時(shí)更應(yīng)記清時(shí)態(tài)的構(gòu)成形式.就本題而言,主要考查現(xiàn)在完成時(shí)態(tài).
