[解析]　 根據(jù)副詞yet可確定用現(xiàn)在完成時，可排除A、C；不定式，動名詞及從句作主語，謂語動詞按單數(shù)處理，when and where to do sth.表示單數(shù)，要用has not been decided。

例4、He will have learned English for eight years by the time he _______from the university next year.

A. will graduate　　　　　　　 B. will have graduated

C. graduates　　　　　　　 　　　D. is to graduate

答案為C。

[解析]　 “by the time”后接定語從句，省略了關系副詞when。在這種定語從句中要用一般現(xiàn)在時表示將來。譯文：到明年他畢業(yè)之前，已經(jīng)學了八年英語。

例6、How I wish every family _______ a large house with a beautiful garden!

A. has　　　　 B. had　　　　 C. will have　　　　 D. had had

答案為B。

[解析]　 wish后接從句常用虛擬語氣，表示這只是說話人的一種愿望。具體用法：如果從句中動作與現(xiàn)在事實相反應用過去式，與將來事實相反用would/could+動詞原形；與過去事實相反用過去完成式或would/could+have done。譯文：我多么希望每個家庭都住上帶有漂亮花園的大房子�！�

A. has been designed　　　　　　　 B. had been designed

C. was designed　　　　　　　 　　　D. would be designed

A. I'm not noticing　　　　　　　　 B. I wasn't noticing

C. I haven't noticed　　　　　　　 D. I don't notice

答案為B。

[解析]　 表示剛才沒有注意到，要用過去進行時。一般現(xiàn)在時表示經(jīng)常性的動作；現(xiàn)在完成時表示過去所做的事對現(xiàn)在造成的影響或從過去某個時候一直延續(xù)到現(xiàn)在的動作，即現(xiàn)在也沒有注意到；現(xiàn)在進行時表示現(xiàn)在正在進行的動作，這三個時態(tài)顯然不符合句意。

例10、A new cinema _______here. They hope to finish it next month.

A. will be built　　　 B. is built　　　 C. has been built　　　 D. is being built

答案為D。

[解析]　 根據(jù)They hope to finish it next month.說明電影院還在建設之中，所以從時態(tài)上講是進行時；另外從語態(tài)上講為被動語態(tài)。
