高一英語上冊Unit3基礎鞏固講解
本單元語法——現在完成時的被動語態
1. —we want to sit at the table near the window.
—i’m sorry，but it ________ already.
a. has taken b. took
c. was taken d. has been taken
解析：選d。從題干中的答語知道，座位已經有人坐了，說明結果。所以應該用現在完成時的被動式。
2. (XX年皖南八校聯考)we’ve been told the good news，but when and where to go for the exciting vacation ________ yet.
a. are not discussed
b. have not been discussed
c. is not being discussed
d. has not been discussed
解析：選d。后一分句的主語為when and where to go for the exciting vacation，表示的是一件事，謂語動詞用單數形式，由此排除a、b兩項。根據句末的yet可知應該用完成時，即這件事還沒有被討論。因此d項正確。
3. (XX年西南師大附中月考)—would you like to go to the cinema with me tomorrow afternoon?
—i’d like to，mum，but i ________ to a party by jane. it is her birthday.
a. am invited b. was invited
c. will be invited d. have been invited
解析：選d。考查時態。這里用現在完成時的被動語態表示過去的動作對現在的影響，即jane已經邀請我參加她的party，故不能陪母親去看電影了。
4. great changes ________ in my hometown and a lot of factories ________.
a. have been taken place；are being set up
b. have taken place；have been set up
c. are taken place；had been set up
d. had taken place；will be set up
解析：選b。take place是不及物動詞詞組，因此沒有被動語態；而 factories和set up之間是被動關系；根據上下文題干可以看出，都應該是現在完成時，所以答案是b項。
5. (XX年江西五校聯考)—why do you look so worried?
—my computer broke down and my essay ________since.
a. has been left unfinished
b. has left to finish
c. was left to finish
d. had been left unfinished
解析：選a。考查動詞的時態和語態。由broke down和since可知時態用現在完成時，且主語與謂語動詞之間是動賓關系，故用被動語態。
