高一下学期英语期末考试临近,定语从句是必考重点,尤其关系副词引导的从句。很多同学在这里丢分,不是因为语法难,而是容易混淆用法。今天,我们用最实用的方法,帮你轻松搞定when、where、why三个关键点,直接提升分数。
一、when:时间状语,重点在“it was the first time”句型
关系副词when表示时间。但有一个特殊句型:It was the first/second/last time that... 这里必须用that,不能用when,从句要用过去完成时。
为什么?因为“第一次”指过去某个时间点之前的事情,用完成时才准确。
例句:It was the first time that I had visited the Great Wall.(这是我第一次参观长城。)
常见错误:学生常写成“It was the first time when I visited...”。考试中,这属于错误。用when会让句子不规范,老师会扣分。
实用技巧:做题时,看到“first time”“second time”“last time”,直接填that,从句用过去完成时。记住口诀:“it was the first time,that是关键”。
练习:试着改写句子。
- 原句:It was the second time that she had missed the bus.
- 改写:She missed the bus for the second time. 但注意从句时态必须用过去完成时。
- 错误写法:It was the second time when she missed the bus. (错误!)
考试中,这类题常出现在阅读理解和改写题里。每天花5分钟练1道,两周就能熟练。
二、where:地点状语,别在具体地点乱用
关系副词where表示地点。但不是所有地点都用where。
当先行词是模糊的地点时,比如point(点)、situation(情况)、case(情形)、position(位置)、stage(阶段)、scene(场景)、spot(地点)、activity(活动)、family(家庭)、job(工作)等抽象名词,才用where。
例句:This is the point where we need to stop discussing.(这是我们需要停止讨论的点。)
对比:如果先行词是具体地点,如city(城市)、school(学校)、park(公园),用where就错了。应该用in which或that。
例句:错误:I live in the city where I was born.
正确:I live in the city in which I was born.
(口语中常用where,但考试必须规范。)
常见错误:学生把“the school where I study”当正确,其实school是具体地点。考试中,如果题目强调规范,会判错。
实用技巧:做题时,先看先行词。如果词是point、situation、case等,直接用where。否则,用其他方式。
- 例句:The situation where we are now is urgent.(正确,situation是抽象词)
- 例句:The place where we met is beautiful.(错误,place是具体地点,应改用in which)
练习:找3个句子改写。
1. The job where I work is challenging. → The job in which I work is challenging.
2. The scene where the accident happened. → The scene in which the accident happened.
3. The point where we agree. → The point where we agree.(正确,point是抽象词)
三、why:原因状语,先行词必须是reason
关系副词why表示原因。先行词必须是reason。
例句:The reason why he was late is that he missed the bus.(他迟到的原因是错过了公交车。)
常见错误:学生写成“The reason because he was late.” 这是错的。why引导从句,不能用because。
实用技巧:记住,reason后面一定跟why。如果句子有reason,就用why。
- 例句:错误:The reason for his failure is because he didn’t study.
- 正确:The reason why he failed is that he didn’t study.
练习:试着造句。
- 正确:The reason why I’m happy is your support.
- 错误:The reason because I’m happy is your support.
考试中,why题常出现在完形填空和写作里。多练几道,就能避免丢分。
如何快速掌握?
1. 先看先行词:做题时,先划出定语从句的先行词,判断类型。
- 时间:用when(如It was the first time...)
- 抽象地点:用where(如point, situation)
- 原因:用why(先行词必须是reason)
2. 重点突破特殊句型:把“it was the first time that...”当成固定模板,反复练习。
3. 每天练10分钟:
- 买本高中英语练习册,找定语从句章节。
- 专注关系副词部分,做5道题,分析错因。
- 例题:
- This is the situation ______ we need to act fast. (where)
- The reason ______ he left is unclear. (why)
- It was the last time ______ I saw her. (that)
4. 总结口诀:
- When for time, first time needs that.
- Where for abstract places, like point and situation.
- Why for reason, no because allowed.
