26. By the time he realizes he ______ into a trap, it’ll be too late for him to do anything about it.

A. walks                   B. walked                 C. has walked            D. had walked

分析：C。此處用現(xiàn)在完成時(shí)表示影響或結(jié)果，句子大意為：等他意識(shí)到已步入陷阱時(shí)，他就來(lái)不及采取補(bǔ)救措施了。

27. —Did you go to the show last night?

—Yeah. Every boy and girl in the area ______ invited.(www.cpsenglish.com)

A. were                    B. have been             C. has been               D. was

分析：D。此題既考查時(shí)態(tài)的用法，同時(shí)又考查主語(yǔ)一致。根據(jù)問(wèn)句中的時(shí)態(tài)和last night這一短語(yǔ)可知，此處談的是昨晚的事，故應(yīng)用一般過(guò)去時(shí)，而不用現(xiàn)在完成時(shí)。另外，根據(jù)英語(yǔ)語(yǔ)法，當(dāng)兩個(gè)或多個(gè)名詞并列作主語(yǔ)，且受到every的修飾時(shí)，其后謂語(yǔ)動(dòng)詞要用單數(shù)。故答案選D。

28. My parents ______ in Hong Kong. They were born there and have never lived anywhere else.

A. live                      B. lived                    C. were living           D. will live

分析：A。根據(jù)第二句用的現(xiàn)在完成時(shí)態(tài)可知，說(shuō)話(huà)者的父母親現(xiàn)在還健在，因此排除選B和C；再根據(jù)第二句句意——他們出生在香港并從未在其他任何地方居住過(guò)——可推他們目前還在香港居住，故選 A。

29. — What is the price of petrol these days?

—Oh, it ______ sharply since last month.

A. is raised                B. has risen               C. has arisen             D. is increased

分析：B。根據(jù)句中的時(shí)間狀語(yǔ)since last month可知，句子應(yīng)用現(xiàn)在完成時(shí)，故可排除A和D。arise意為“出現(xiàn)，發(fā)生，（煙等）從……升起”；rise意為 “（價(jià)格、溫度、量等）上升、增加”。故選B。又如：It’s rained steadily since last Saturday. 自從上星期六以來(lái)一直下雨。

30. His sister left home in 1998, and ______ since.

A. had not been heard of                            B. has not been heard of

C. had not heard of                                    D. has not heard of

分析：B。根據(jù)句末的副詞since可知，句子應(yīng)用現(xiàn)在完成時(shí)，故可排除選項(xiàng)A和C；再根據(jù)his sister和謂語(yǔ)hear of之間的動(dòng)賓關(guān)系，可確定答案為B。句意為：他妹妹1998年離家后再也沒(méi)有消息。

31. Progress ______ so far very good and we’re sure that the work will be finished on time.

A. was                      B. had been               C. has been               D. will be

分析：C。根據(jù)句中so far(到目前為止)可知判斷，句子應(yīng)用完成式；再根據(jù)后面一句中的時(shí)態(tài)來(lái)判斷，句子應(yīng)用現(xiàn)在完成時(shí)。句意為：到目前為止進(jìn)展非常順利，我們相信這項(xiàng)工作將會(huì)如期完成。又如：So far the work has been easy but things may change. 到目前為止，這工作很容易，但情況可能有變化。

32. This is the first time we ______ a film in the cinema together as a family.

A. see                       B. had seen               C. saw                      D. have seen

分析：D。根據(jù)英語(yǔ)習(xí)慣，在It / This / That is the first / second time+(that)…句型中，從句一般用現(xiàn)在完成時(shí)。句意為：這是我們作為一家人第一次在電影院看電影。又如：This is the first time I’ve seen you wearing a dress. 這是我第一次看到你穿一件連衣裙。
