1、2022年人教版高中英語必修一Unit 4《Earthquakes》（第3課時）word教案
教學目標：語法——現(xiàn)在完成時
重難點突破：
1. 現(xiàn)在完成時的構(gòu)成：主語+have(has)+過去分詞(done)
2. 用法：
(1) 現(xiàn)在完成時用來表示現(xiàn)在之前已發(fā)生過或完成的動作或狀態(tài),但其結(jié)果卻和現(xiàn)在有聯(lián)系,也就是說,動作或狀態(tài)發(fā)生在過去但它的影響現(xiàn)在還存在. 常與for,since連用.
I have lost my wallet.(含義是:現(xiàn)在我沒有錢花了.)
Jane has laid the table.(含義是:簡已在吃飯.)
Michael
2、has been ill.(含義是:現(xiàn)在仍然很虛弱)
He has returned from abroad. (含義是:現(xiàn)在已在此地)
Mary has been ill for three days.
I have lived here since 1998.
(2) 現(xiàn)在完成時往往同表示不確定的過去時間狀語連用,如already, yet, just, before, recently,still, lately等:
He has already obtained a scholarship.
I haven't seen much of him r
3、ecently (lately).
We have seen that film before.
Have they found the missing child yet ？
(3) 現(xiàn)在完成時常常與表示頻度的時間狀語連用,如often, sometimes, ever, never, twice, on several occasions等:
Have you ever been to Beijing
I have never heard Bunny say anything against her.
I have used this pen on
4、ly three times. It is still good.
George has met that gentleman on several occasions.
還可以同包括現(xiàn)在時間在內(nèi)的時間狀語連用,如now, up to these few days/weeks/months/years, this morning/week/month/year, now, just, today, up to present, so far等:
Peter has written six papers so far.
Man has now learned to r
5、elease energy from the nucleus of the atom.
There has bee too much rain in San Francisco this year.
Up to the present everything has been successful.
(4) 現(xiàn)在完成時與for引起的短語連用時，表達從過去開始的動作或狀態(tài)延續(xù)至今，而一般過去時與“for+一段時間”連用時，只指過去的動作或狀態(tài)在過去延續(xù)了多長時間。
We've stayed here for three weeks. 我們在這里呆了三個星期了。（說話時人還在）
6、。
He stayed here for three weeks last year. 他過去曾在這里呆過三個星期。（并不表示現(xiàn)在是否在）
(5) have?gone?to和have?been?to的區(qū)別：
前者表示某人“去某地了”，這個人已經(jīng)不在這里了，常用于第三人稱。
后者表示某人“去過某地，現(xiàn)在已經(jīng)回來了”，常與ever等連用可用于各人稱：
She?has?gone?to?England.?她到英國去了。
She?has?been?to?England.她去過英國。
“Where?is?Tom?”“He?has?gone?to?the?post?office.”（To
7、m目前不在說話處）
Have?you?ever?been?there??你曾經(jīng)去過那里嗎？（說話人you目前在說話處）
