八年級英語Past and present教案
9. 誤：i saw the film twice already.
正：i’ve seen the film twice already.
解析：本題主要是一般過去時態與現在完成時態的概念錯誤。這電影我已看過兩遍，說明我現在對電影內容很了解，故要用現在完成時態。
10. —______you _____ your watch?
— no, ______.
a. did, find out, i didn’t b. have, found, not yet
c. have, looked for, i haven’t d. did, find, not yet
答案：選“b”。全句應用現在完成時，強調到現在為止的情況“是否找到了手表”，答語：not yet 相當于說 i haven’t found it yet.
11. i have never seen the film ______.
a. ago b. just now c. before d. later
答案：選“c”。動詞時態為現在完成時，與之搭配的詞必須是ever, never, already, yet, before, recently 等詞。而 ago, just now 等只能用于一般過去時的句子中，用later意思不通。
12. aunt li _________ her home town for a long time.
a. has left b. left c. has gone to d. has been away from
答案：選“d”。與 for a long time搭配的動詞應該表示延續性，go, leave是短暫動詞，故不能選。
