在高二这个关键的学习阶段，英语作为一门重要的学科，其学习效果直接影响到未来的高考成绩。为了帮助同学们更好地掌握英语知识，提高英语水平，下面提供一套高二英语试题及其参考答案。
一、单项选择题
1. The boy ________ his homework when his mother came in.
A. was doing B. did C. has done D. is doing
正确答案：A
解析：此题考查的是过去进行时的用法。当主句描述的是过去某个时间点正在进行的动作时，从句中通常使用过去进行时。因此，这里应该选择“was doing”。
2. If it ________ tomorrow, we will stay at home.
A. rains B. will rain C. is raining D. rained
正确答案：A
解析：此题考察的是条件状语从句中的时态。根据“主将从现”的原则，在条件状语从句中，如果主句是一般将来时，则从句应使用一般现在时表将来。所以正确答案是“rains”。
3. She ________ to the party last night but she didn't enjoy it very much.
A. invited B. was invited C. had been invited D. has been invited
正确答案：B
解析：本题考查被动语态。句子表达的意思是她被邀请参加了昨晚的聚会，但并未玩得开心。由于动作发生在过去，且强调的是被动关系，故应选用一般过去时的被动语态形式“was invited”。
二、完形填空
阅读下面短文，从每小题所给的四个选项(A、B、C和D)中选出最佳选项，并将其字母标号填写在答题卡相应位置上。
The summer vacation is coming. Many students are making plans for their holidays. Some want to travel abroad while others prefer to stay at home and read books or watch movies. No matter what they choose, it's important to have fun and learn something new during this time.
(1) A. studying B. working C. traveling D. resting
正确答案：C
解析：根据上下文可知，此处指的是学生们计划假期活动，而“traveling”最符合语境。
(2) A. although B. because C. so that D. unless
正确答案：B
解析：“because”引导原因状语从句，表示“因为”，符合逻辑关系。
三、阅读理解
根据短文内容判断正误：
Short Story: Once upon a time, there was a little girl named Lily who loved animals. One day, she found an injured bird on her way home from school. She took it home and cared for it until it got better. From then on, Lily decided to protect all living creatures.
Question: Did Lily take care of the bird?
Answer: True
解析：短文中明确提到Lily把受伤的小鸟带回家并照顾它直到康复，因此该陈述为真。
以上就是本次提供的高二英语试题及答案。希望大家通过练习能够巩固所学知识，提升自己的英语能力！
