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

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。此题既考查时态的用法，同时又考查主语一致。根据问句中的时态和last night这一短语可知，此处谈的是昨晚的事，故应用一般过去时，而不用现在完成时。另外，根据英语语法，当两个或多个名词并列作主语，且受到every的修饰时，其后谓语动词要用单数。故答案选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。根据第二句用的现在完成时态可知，说话者的父母亲现在还健在，因此排除选B和C；再根据第二句句意——他们出生在香港并从未在其他任何地方居住过——可推他们目前还在香港居住，故选 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。根据句中的时间状语since last month可知，句子应用现在完成时，故可排除A和D。arise意为“出现，发生，（烟等）从……升起”；rise意为 “（价格、温度、量等）上升、增加”。故选B。又如：It’s rained steadily since last Saturday. 自从上星期六以来一直下雨。

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。根据句末的副词since可知，句子应用现在完成时，故可排除选项A和C；再根据his sister和谓语hear of之间的动宾关系，可确定答案为B。句意为：他妹妹1998年离家后再也没有消息。

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。根据句中so far(到目前为止)可知判断，句子应用完成式；再根据后面一句中的时态来判断，句子应用现在完成时。句意为：到目前为止进展非常顺利，我们相信这项工作将会如期完成。又如：So far the work has been easy but things may change. 到目前为止，这工作很容易，但情况可能有变化。

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。根据英语习惯，在It / This / That is the first / second time+(that)…句型中，从句一般用现在完成时。句意为：这是我们作为一家人第一次在电影院看电影。又如：This is the first time I’ve seen you wearing a dress. 这是我第一次看到你穿一件连衣裙。
