2026年中考英语重点语法条件&目的&结果状语从句考点专项练习卷

中考重点语法条件&目的&结果状语从句考点专项练习卷
第一部分：考点精讲
一、 条件状语从句 (Adverbial Clause of Condition)
1. 定义： 由一个条件（通常由if, unless等引导）引出主句的结果。
2. 常见引导词：
if (如果)
unless (除非，如果不) 【注意：unless = if not】
as/so long as (只要)
on condition that (条件是...)
3. 核心考点：主将从现
这是中考最高频的考点，没有之一！
规则： 当主句是将来时（或含有情态动词，或是祈使句）时，条件从句要用一般现在时来表示将来。
公式：If + 主语 + do/does (现在时), 主语 + will/can/may/must... + do (将来时) / 祈使句
例句：
If it rains tomorrow, we will cancel the picnic. (如果明天下雨，我们将取消野餐。)
You will not pass the exam unless you study hard. (= ...if you do not study hard.) (除非你努力学习，否则你考试会不及格。)
Call me if you need any help. (祈使句作主句) (如果你需要帮助就叫我。)
4. 易错点：
混淆 if 和 unless 的意思。unless 表示“除非”，是一种否定的条件。
在条件从句中错误使用 will。例如：If it will rain, I will stay home. ( ) -> 应改为 If it rains, I will stay home. ( )
二、 目的状语从句 (Adverbial Clause of Purpose)
1. 定义： 表示主语做某事的目的或意图。
2. 常见引导词：
so that (为了，以便) 【最常用】
in order that (为了) 【更正式】
核心考点：从句中的情态动词
目的状语从句的谓语通常包含情态动词 can, could, will, would, may, might 等。
例句：
He got up early so that he could catch the first bus. (他早起是为了能赶上头班车。)
The teacher spoke slowly in order that every student might understand her. (老师说得很慢，以便每个学生都能听懂。)
4. 同义转换（高频考点！）：
so that / in order that 从句 ≈ to do / in order to do / so as to do (不定式短语)
转换方法： 当主句和从句主语一致时，可以进行转换。
He got up early to catch the first bus.
He got up early in order to catch the first bus.
三、 结果状语从句 (Adverbial Clause of Result)
1. 定义： 表示主句动作所导致的结果。
2. 常见引导词：
so... that... (如此...以至于...)
such... that... (如此...以至于...)
3. 核心考点：so vs. such 的区别
这是中考的绝对重点和难点！
引导词 结构 例句
so so + adj./adv. + that He is so honest that everyone trusts him. (他如此诚实，以至于每个人都信任他。)
so + many/few + 可数名词复数 + that There are so many people that I can't move. (人太多了，我动不了。)
so + much/little + 不可数名词 + that She has so much energy that she never feels tired. (她精力如此充沛，从不觉得累。)
such such + a/an + adj. + 可数名词单数 + that It was such a hot day that we all went swimming. (天如此热，我们都去游泳了。)
such + adj. + 可数名词复数 + that They are such kind people that they always help others. (他们是如此善良的人，总是帮助别人。)
such + adj. + 不可数名词 + that This is such useful information that I'll write it down. (这信息太有用了，我要把它记下来。
记忆口诀： “名”前such，“形/副”前so；many/much/little/few前，只用so不用such。
4. 易错点：
混淆 so 和 such 后面所接的词性。
忽略 so that 既可以引导目的状语从句（意为“为了”），也可以引导结果状语从句（意为“所以”）。区分的关键是：目的从句常含情态动词（can, may等），而结果从句是客观事实，通常没有情态动词。
I got up early so that I could catch the train. (目的：为了能赶上)
I got up early, so that I caught the train. (结果：所以我赶上了)

第三部分：答案与解析
I. 单项选择
1.A 【解析】句意：如果你不快点，你上学就会迟到。表示条件，用if。
2.A 【解析】句意：这个箱子如此重，以至于没人能搬动它。heavy是形容词，用so... that...结构。
3.C 【解析】句意：当我到达上海时，我会给你打电话。when引导时间状语从句，符合语境。
4.A 【解析】句意：——当然可以，只要你先完成作业。as long as表示“只要”，引导条件状语从句。
5.C 【解析】句意：他大声说话，以便每个人都能听清楚。could hear包含情态动词，表示目的，用so that。
6.C 【解析】句意：它是如此有趣的一本书，以至于我读了两遍。book是可数名词单数，interesting以元音音素开头，用such an... that...。
7.C 【解析】句意：除非你多练习，否则你的英语不会提高。unless = if not，“如果不多练习”。
8.A 【解析】句意：有如此多的噪音，以至于我无法入睡。noise是不可数名词，much修饰不可数名词，其前用so。
9.B 【解析】句意：我们很早出发，为了能准时到达那里。could get包含情态动词，表示目的。
10.A 【解析】句意：这个问题如此难，以至于没几个学生能解出来。difficult是形容词，用so... that...。few（很少，表否定）修饰可数名词复数。
II. 同义句转换
1.so that he could catch the bus 【解析】目的状语从句转换。
2.such a beautiful park that many people visit it every day 【解析】park是可数名词单数，用such a... that...。
3.unless you water them 【解析】unless 表示“除非”，后面接肯定形式you water them，意思等同于if you don't water them。
4.too boring to watch (或 too boring for me to watch) 【解析】too... to...结构表示“太...而不能...”。原句主语是I，转换后逻辑主语需一致。
5.in order not to get lost 【解析】in order to的否定形式直接在to前加not。主语一致，可用不定式转换。
III. 句子改错
1.If it is sunny tomorrow, we will go hiking.
【解析】条件状语从句中，if引导的从句要用一般现在时(is)代替将来时(will be)。
2.He is so careful that he never makes mistakes.
【解析】careful是形容词，前面应该用so，而不是such。
3.(正确)
【解析】so that引导目的状语从句，且从句中含有情态动词can，用法正确。
4.If we don't protect the environment, our earth will get worse. 或 Unless we protect the environment, our earth will get worse.
【解析】unless本身就等于if not，后面不能再加not，否则意思就变成“除非我们不保护...”，逻辑错误。
5.He has so few friends that he often feels lonely.
【解析】friends是可数名词复数，表示“少”应用few，little修饰不可数名词。
