高二英語Music教案
這幾個星期我一直在告訴你要小心。iii. the main differences between the present perfect tense and the present perfect progressive tense.1. 在不用時間狀語的情況下，現在完成進行時表示動作仍在持續進行，而現在完成時則表示動作在過去已經結束。
例句：(1)we have been cleaning the classroom.我們一直在打掃教室。
(2)we have cleaned the classroom.我們把教室打掃過了。(3)they have been widening the road.他們一直在加工馬路。（尚未完工）(4)they have widened the road.他們把馬路拓寬了。（已經完工了）
2. 現在完成進行時往往表示動作在重復，現在完成時則常常不帶重復性。例句：(1) have you been meeting her lately?你最近跟她見面嗎？（有“經常相會”之意）
(2)have you met her lately?你最近跟她見過面了嗎？（沒有“經常相會”之意）
3.表示暫時性動作用現在完成進行時較好，而表示表示長時期的接近于狀態的動作時，用現在完成時較好。例句：(1) he has been staying with his uncle during the past two months.最近兩個月他和他叔叔在一起（暫時性動作）(2) i have been waiting all the morning.早晨我一直在等（暫時性動作）
(3) i have lived here all my life.我一輩子一直住這兒。（長時期的接近于狀態的動作）(4) we have worked in the south since we graduated.畢業后我們一直在南方工作。 （長時期的接近于狀態的動作）
4.有些表示狀態、感情、感覺的動詞，如：have, exist, like, hate, hear, know, sound等，不能用于現在完成進行時，但可用于現在完成時。例句：(1) they’ve known each other since 1970.（不用they have been knowing…）自1970年起他們就認識了。
(2) john has loved mary since ten years ago. 約翰自十年前就愛上了瑪麗。(3) he has been here for two days.他在這兒兩天了。(4) the property has belonged to my uncle during the last ten years.十年來這財產一直是我叔叔的。
5. 在否定句中一般用現在完成時而不用現在完成進行時。例句：(1) i have not spoken（而不說have not been speaking) english for two years.
(2) he has never seen a man like him.(3) he has hardly met an american in the street.(4) i have received no money from my family.step 3. practice about the present perfect progressive tense.
i. complete the conversation. put the verbs into the present perfect progressive.
