在高考英语备考过程中，语法填空题型是考生必须熟练掌握的重要部分。这类题目考察的是学生对英语语法知识的综合运用能力，包括词汇搭配、时态语态、从句结构等知识点。为了帮助同学们更好地准备这一部分，我们特别整理了以下专项训练题，并附上详细的答案解析。

一、语法填空专项练习

1. The teacher said that reading every day (help) you improve your vocabulary.

2. If it (rain) tomorrow, the school sports meet will be canceled.

3. She was very tired after working for hours without (stop).

4. By the time he arrived at the station, the train (leave).

5. I didn't know which book (choose), so I took both of them.

6. He promised (call) me as soon as he got home.

7. It is important (learn) English well if you want to study abroad.

8. Although she tried her best, she still failed (pass) the exam.

9. We have been friends since we (meet) in primary school.

10. The movie was so interesting that everyone present (enjoy) it.

二、答案解析

1. helps

此题考查主谓一致与一般现在时。句子主语为“reading every day”，是第三人称单数形式，因此助动词应使用“helps”。

2. rains

此题涉及虚拟语气。if引导的条件状语从句中，若表示与将来事实相反的情况，则从句用一般现在时表假设。

3. stopping

without后需接名词或动名词形式，“stop”变为“stopping”。

4. had left

by the time引导的时间状语从句强调过去某个时间点之前已经完成的动作，因此主句应使用过去完成时。

5. to choose

此处考察固定搭配“don't know what/which...to do”，表示不知道该做什么。

6. to call

promise后常接不定式作宾语，“promise to do sth.”意为承诺做某事。

7. to learn

it is + adj.+ to do sth. 是常用句型，表示做某事很重要。

8. to pass

fail后接不定式短语，表示未能做到某事。

9. met

since引导的时间状语从句中，通常使用一般过去时描述过去的动作或状态。

10. enjoyed

so...that结构连接两个分句，后一分句描述结果，使用过去式与主句时态保持一致。

通过以上练习，相信同学们对语法填空题有了更深的理解。希望这些题目能够帮助大家在高考中取得优异的成绩！如果还有其他疑问，欢迎随时咨询老师或查阅相关资料进一步巩固学习成果。
