1选择题
Look! The children ______ kites in the park. They look so happy.
- A. fly
- B. flies
- C. are flying
- D. flew
答案：C
解析：本题考查现在进行时。句首的“Look!”是现在进行时的典型标志词，表示动作正在进行。主语“The children”是复数，所以be动词用“are”，后接动词-ing形式。易错点：学生可能忽略“Look!”这个信号词，而误选一般现在时A或B。
2选择题
My father ______ a doctor twenty years ago. He loved his job very much.
- A. is
- B. was
- C. has been
- D. will be
答案：B
解析：本题考查一般过去时。时间状语“twenty years ago”明确表示过去的时间，因此谓语动词需用过去式。主语“My father”是第三人称单数，be动词的过去式用“was”。易错点：学生可能受“loved”影响，但关键在于时间状语，且前后时态需保持一致。
3选择题
We ______ have a picnic if it ______ fine tomorrow.
- A. will; is
- B. will; will be
- C. /; is
- D. /; will be
答案：A
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，用一般现在时表示将来，主句用一般将来时。因此，主句用“will have”，从句用“is”。易错点：学生可能在从句中也使用将来时“will be”，这是常见错误。
4选择题
The book ______ into many languages since it was published.
- A. translates
- B. translated
- C. has been translated
- D. was translated
答案：C
解析：本题考查现在完成时的被动语态。时间状语“since it was published”表示从过去某一时间持续到现在，应用现在完成时。主语“The book”与动词“translate”是被动关系，且动作发生在过去，对现在有影响，所以用现在完成时的被动语态“has been translated”。易错点：学生可能忽略“since”标志词，或忘记被动语态结构“be + 过去分词”。
5填空题
The teacher told us that the earth ______ (go) around the sun.
答案：goes
解析：本题考查宾语从句中的时态。当宾语从句陈述的是客观真理、自然现象时，无论主句用什么时态，从句一律用一般现在时。“地球绕着太阳转”是客观真理，所以填“goes”。易错点：学生可能受主句“told”（过去时）影响，错误地将从句也改为过去时“went”。
6填空题
By the time I got to the station, the train ______ (leave).
答案：had left
解析：本题考查过去完成时。句式“By the time + 过去时从句，主句...”表示“到...时候为止”，主句动作发生在从句动作之前，即“过去的过去”，需用过去完成时（had + 过去分词）。易错点：学生可能只看到“got”而误用一般过去时“left”。
7解答题
根据要求完成句子，每空一词。
1. He cleans his room every day. (改为被动语态)
His room ______ ______ by him every day.
2. She asked me, “Where do you live?” (改为间接引语)
She asked me ______ I ______.
答案：1. is cleaned
2. where; lived
解析：本题综合考查被动语态和宾语从句。
1. 一般现在时的被动语态结构为“am/is/are + 过去分词”。主语“His room”是第三人称单数，故用“is cleaned”。易错点：学生可能忘记将“clean”变为过去分词“cleaned”，或be动词用错。
2. 直接引语变间接引语，需将疑问语序改为陈述语序，并注意时态一致。主句“asked”是过去时，从句时态需相应变为过去时。易错点：学生可能保留疑问语序“where do you”，或忘记将“live”变为“lived”。
8解答题
阅读下面短文，用括号内所给动词的适当形式填空。
Last Sunday, my family and I went to the countryside. The air there was very fresh. We ______ (enjoy) the beautiful scenery and ______ (take) many photos. Suddenly, we saw a rabbit. It ______ (run) so fast that we couldn't catch it. We ______ (have) a great time there.
答案：enjoyed; took; ran; had
解析：本题考查在具体语境中综合运用动词时态的能力。整个短文描述的是过去（Last Sunday）发生的一系列事情，因此所有动词都应使用一般过去时。
1. enjoy -> enjoyed
2. take -> took (不规则动词过去式)
3. run -> ran (不规则动词过去式)
4. have -> had (不规则动词过去式)
易错点：学生可能忽略全文的过去时语境，或对不规则动词的过去式掌握不牢（如take-took, run-ran）。
