表示結(jié)果的現(xiàn)在完成時(shí)
現(xiàn)在完成時(shí)著眼于過去的動(dòng)作對(duì)現(xiàn)在產(chǎn)生的結(jié)果或影響。這是現(xiàn)在完成時(shí)的“已完成”用法,表示動(dòng)作或過程發(fā)生在說話之前就已完成,并與現(xiàn)在有聯(lián)系。這種聯(lián)系實(shí)際上就是“過去的動(dòng)作”對(duì)現(xiàn)在的影響或產(chǎn)生的結(jié)果。
I have bought a pen.
我買了一支筆。(結(jié)果:I have a pen now.)
The temperature has increased by 10℃.
溫度上升了10攝氏度。(結(jié)果:It is quite hot now.)
Air pollution has taken the lives of many people.
空氣污染已經(jīng)奪去了很多人的生命。(結(jié)果:Air pollution is very serious now.)
注意:
現(xiàn)在完成時(shí)的上下文所指的時(shí)態(tài)必須呼應(yīng)。
【誤】I have bought a pen but I have lost it now.(have bought表示你現(xiàn)在已經(jīng)有筆了,這和后面的have lost有矛盾)
【正】I bought a pen but I have lost it now.
我(過去)買了一支筆,但我已經(jīng)把它丟了。
【誤】I have lost my pen but I have found it now.(have lost強(qiáng)調(diào)你現(xiàn)在已經(jīng)沒有筆了,與后面have found的意思有沖突)
【正】I lost my pen but I have found it now.
我丟了一支筆,但現(xiàn)在已經(jīng)找到了。
