Grammar
現(xiàn)在完成時（2）
現(xiàn)在完成時如何使用呢？
當我們要表達“某人曾經做過某事”，“某人已經做了某事”等意思時，英語要用“現(xiàn)在完成時”來表達。
現(xiàn)在完成時的結構：
has/have+done(動詞過去分詞)
肯定句    否定句    疑問句
I/We/You/They have done...   I/We/You/They have not(haven't)done..Have you/they done..?
He/She has done...   He/She has not(hasn't)done... Has he/she done...?
表達“剛剛做完某事”?！耙呀涀鐾昴呈隆睍r，使用現(xiàn)在完成時。如：
1.I have just heard the news. 我剛剛聽到消息。
2.Astronauts have already been to the moon.宇航員已經去過月球了。
3.We have just started to explore other planets.我們才剛剛開始探索其他行星。
just“剛剛”，already“已經”，兩者都用于肯定句中，一般置于have/has之后。否定句中則用yet，表示“還（未）”。如：
The scientists have not heard from it yet.科學家還沒收到他發(fā)出的信息。
Man has discovered any life in space yet.人類尚未在太空中發(fā)現(xiàn)生命。
常與現(xiàn)在完成時連用的副詞：
already，just，ever，yet，never
肯定句：already，just
疑問句和否定句：never，yet，never，yet常置于句末。
already，just，ever，never一般置于助動詞have/has之后，過去分詞之前。
A:Have you...?
B:Yes,.../No,...
(using already,just,never,ever,yet,never)
現(xiàn)在完成時與一般過去時
現(xiàn)在完成時表示該事件是在現(xiàn)在之前的某一個事件里發(fā)生的，重點在于強調這一動作與現(xiàn)在的影響
一般過去時只表示過去的某一個具體實踐發(fā)生的事情
I have just been to London.I went there last month.
我剛剛去過倫敦，是上個月去的。
I have already finished my homework.
I finished it an hour ago.
我已經寫完作業(yè)了，一個小時之前完成的。

A:Where have you put my book?I can't find it.
B:I put it on your desk yesterday.
當A問對方把自己的書放在何處時，他在意的是書目前在哪兒，故用現(xiàn)在完成時。
B的回答著重的是當時的動作，故用一般過去時。
