1选择题
— Where is Mr. Wang? — He ______ to the science museum with his students. They will be back in two hours.
- A. goes
- B. went
- C. has gone
- D. is going
答案：C
解析：本题考查时态辨析。根据答语“他们两小时后回来”可知，王老师现在不在这里，去了科技馆还没回来，表示“去了某地（人未回）”，应用现在完成时 have/has gone to。A项为一般现在时，表示经常性动作；B项为一般过去时，只强调过去去了，未体现对现在的影响；D项为现在进行时，表示正在去。故选C。
2选择题
Many new high-speed railways ______ in China every year, making travel much faster.
- A. build
- B. are built
- C. built
- D. were built
答案：B
解析：本题考查被动语态。句意为“中国每年建设许多新的高速铁路”，主语 railways 与动词 build 之间是被动关系，且由 every year 可知用一般现在时的被动语态。A、C为主动语态，时态也不符；D为一般过去时被动语态。故选B。
3选择题
If it ______ tomorrow, we will put off the robotics competition.
- A. will rain
- B. rained
- C. rains
- D. is raining
答案：C
解析：本题考查 if 引导的条件状语从句中的时态。在 if 引导的条件状语从句中，要用一般现在时表示将来，主句用一般将来时。A项为一般将来时，不能用于条件从句；B项为一般过去时，不符合语境；D项为现在进行时。故选C。
4填空题
The astronauts ______ (land) on the moon safely last night. We are so proud of them.
答案：landed
解析：本题考查一般过去时的用法。由时间状语 last night 可知，句子应用一般过去时。动词 land 的过去式是规则变化，直接加 -ed。易错点：忽略时间状语，误用现在时或进行时。
5解答题
根据上下文，用所给动词的正确时态填空。
(1) Look! The engineers ______ (test) a new type of solar-powered car in the lab.
(2) My father ______ (work) as a software engineer for ten years. He still enjoys his job very much.
(3) The teacher told us that the earth ______ (go) around the sun.
答案：(1) are testing (2) has worked (3) goes
解析：(1) Look! 提示动作正在进行，用现在进行时 are testing。(2) for ten years 表示动作从过去持续到现在，用现在完成时 has worked。(3) 客观真理用一般现在时，主语 the earth 是第三人称单数，故填 goes。易错点：(1) 漏看 Look! 提示；(2) 混淆现在完成时和一般过去时；(3) 在宾语从句中误用过去时。
6解答题
将下列句子改为被动语态。
We must finish the project design before next Monday.
答案：The project design must be finished (by us) before next Monday.
解析：主动句含情态动词 must，变被动语态结构为“情态动词 + be + 过去分词”。将原句宾语 the project design 变为主语，动词 finish 变为 be finished。原主语 we 可变为 by us，也可省略。易错点：漏掉 be 动词，直接写 must finished。
7解答题
根据中文提示，完成英文句子，每空一词。
我不知道他是否会对这个人工智能程序感兴趣。
I don't know ______ he ______ be interested in this AI program.
答案：if/whether; will
解析：本题考查 if/whether 引导的宾语从句及一般将来时。第一个空引导宾语从句，表示“是否”，用 if 或 whether；第二个空根据中文“会对...感兴趣”可知用一般将来时 will be。易错点：第一个空漏写引导词；第二个空误用一般现在时 is。
