名师提醒：遇到复合句解题时，应当仔细分析句子成分，判断从句类型，根据逻辑意义正确解题。
考点一 条件状语从句
知识点 1 if, unless 引导条件状语从句的情况
if 和 unless 引导的条件状语从句。if 表示正面的条件，意为“如果”；unless(＝if ... not)表示反面的条件，意为“除非，如果
不”。if 可引导非真实条件状语从句(见＂虚拟语气＂)和真实条件状语从句。
名师提醒：条件状语从句和时间状语从句一样，当主句是将来时的时候，从句要用一般现在时。
例1. You'll fail the exam unless you study hard(＝if you don't study hard)．（真实）
除非你努力学习，否则你考试会不及格。
例2. If you had come a few minutes earlier, you would have met him.（虚拟）
要是你早来几分钟就碰到他了。
例3. However, if I need to check the origin of a word or to look up examples of its usage, there's nothing better.
【2024 年新高考 I 卷】
然而，如果我需要检查一个单词的起源或查找它的用法的例子，没有什么更好的了。
例4. Unless it rains, the game will be played. （unless 引导从句，语气较强）
除非下雨，比赛将照常进行。
例5. Bicycles are available if needed.【2021 年天津卷】
如果需要的话，我们可以提供自行车。
名师提醒：在条件状语从句中，如果从句中主语和主语一致，并且含有 be 动词，可以省略从句中的主语和 be 动词。故
例 5 中可以视为 if bicycles are needed 的省略。
典例 1.（2021 年浙江卷改编）_________ I have to be out of town, each week I take my mother to do her shopping and
visit the doctor, providing company and transportation.
【解析】分析句子结构可知，本句是复合句。从句缺少引导词，根据句子逻辑关系和句意可知表条件。句意：除非必须
出城，否则每个星期我都会陪伴母亲去购物、看医生。
【答案】Unless
典例 2.（广东省 2023-2024 学年普通高三调研试题）As Mofu comes, the weather gradually turns cool and people may get cold
they keep eating noodles and sweat a lot.
【解析】考查连词。句意：随着末伏的到来，天气逐渐转凉，如果人们继续吃面条会出很多汗，这样他们可能会感冒。
此处表示“如果”，应用 if 引导条件状语从句，故填 if。
【答案】if
变式训练 1．If you are capable of playing the piano well, you (have) the opportunity to join their band.
【解析】考查动词时态。句意：如果你钢琴弹得好，你就有机会加入他们的乐队。分析句子可知，此处为 if 引导的条件
状语从句，遵循主将从现原则，所以此处主句时态应为一般将来时。故填 will have。
【答案】will have
变式训练 2．A small car is big enough for a family of three you need more space for baggage.
【解析】考查连词。句意：一辆小车对一个三口之家来说足够大了，除非你需要更大的空间放行李。根据句意可知，此
处应用连词 unless“除非，如果不”引导条件状语从句。故填 unless。
【答案】unless
知识点 2 in case, on condition, providing(that)等引导条件状语从句的情况
in case, on condition that, providing(that), provided (that)，supposing (that), suppose (that)等词汇意思相近，意为“万
一，假使，假如，在……条件下”。
例1. In case there is a fire, what will we do first
万一发生火灾，我们首先要做什么？
例2. Suppose/Supposing(that) they refuse us, who else can we turn to for help
假如他们拒绝了我们，我们还能求助于谁？
例3. They agreed to lend us the car on condition that we returned it before the weekend.
他们同意把车借给我们，条件是我们在周末前归还。
例4. I will agree to go provided that (providing that) my expenses are paid.
如果帮我支付费用，我就同意去。
知识点 3 as long as, so long as 引导条件状语从句的情况
as long as(＝so long as)引导语气强烈的条件状语从句，意为“只要”。
例 1. As long as you don't lose heart, you will succeed.
你只要不灰心，就会成功。
例2. “As long as I get close enough, no criminal can escape from me,” he said.【2021 年新高考 II 卷】
他说：“只要我离得够近，任何罪犯都逃不掉。”
例3. So long as one keeps calm, one doesn’t feel the heat too much.
心静自然凉。
知识点 4 if only 引导条件状语从句的情况
if only “如果……就好了”和 only if “只有”也可以引导条件状语从句。但是当 only if 置于句首时，主句部分倒装。
例1. If only I were as clever as you. （虚拟语气对现在情况的虚拟）
我要是像你一样聪明就好了。
例2. If only I had gone by taxi.（虚拟语气对过去情况的虚拟）
要是我乘出租车去就好了。

律师只有打赢官司才会被付费。
考点二 时间状语从句
知识点 1 when, while, as 引导时间状语从句的情况
when, while, as
从句谓语动词为延续性动词或非延续性动词。从句的动作和主句的动作可以同时发生，也可
when 以先后发生。译为“当……时；在……期间”。
When I lived there, I used to go to the seashore on Sundays.我住在那里时，星期天常到海滨去。
从句的谓语动词为延续性动词。从句的动作与主句的动作同时发生
while
Please don't talk so loud while others are working.在别人工作的时候，请别这么大声音说话。
从句谓语一般为延续性动词。从句的动作与主句的动作同时发生或交替进行，可译为“一
as
边……，一边……；随着……”
As time goes on, it's getting warmer and warmer.随着时间的推移，天气变得越来越温暖了。
名师提醒 1. 如果主句表示的是短暂性动作，而从句用延续性动词的进行时表示在一段时间内正在进行的动作时，
when/while/as 可以互换使用。2. when 还可表原因，意为“既然”。
When/While/As I was walking down the street， I came across an old friend of mine.
我正沿着大街走时，碰巧遇到了我的一位老朋友。

用不了多久我们就会再见面。
It was three days before he came back.（过了......才......）
过了三天他才会来。
2. since 引导的从句如果用非延续性动词，所表示的动作自从句谓语动词所表示的动作开始时算起；若用延续性动词，所
表示的动作自从句谓语的动作或状态的完成或结束时算起。
It’s three years since he joined the army.(自从......多久了......)
自从他参军已经三年了。
It's two years since we arrived here.
我们到这儿两年了。
It's three years since we lived here.
我们不住在这里有三年了。
3. “It be＋时间状语＋that＋其他”构成强调句型，意思是“正是在某一时间发生了某事”。
It was at eight o'clock that we got home.
正是在八点我们到了家。
4. “It be＋时间点＋when 从句”表示“某事发生在什么时间”，it 指代时间。
It was six o'clock when we got home.
当我们到家的时候六点了。
知识点 3 till, until, not...until 引导时间状语从句的情况
1. “延续性动词(肯定式)＋until/till”表示“动作延续到……为止”。
例 1. We walked along the river until/till it was dark.

例1. Until you told me I had no idea of it.
直到你告诉我，我才知道这件事。
例2. Not until the film began did she arrive.
直到电影开始她才到。
知识点 4 其它连词引导时间状语从句的情况
1. 表示“一 ......就 ......”：as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner ...
than ..., hardly/scarcely ... when ... 和 once(一……就……)
从句中常用一般时态代替将来时。
例1. The moment I heard the voice，I knew Father was coming.
我一听到那个声音就知道父亲来了。
例2. The boy burst into tears immediately he saw his mother.

刚到火车站，这个小偷就被逮捕了。
例2. On his arrival in Paris he was recognized as a noble and thrown into prison.
他刚到巴黎，就被认出是位贵族并被投入监狱。
3. no sooner ... than ...，hardly/scarcely ... when ... 句型的时态运用：主句的谓语动词应用过去完成时，而 than 与 when

He had no sooner finished his speech than the students started cheering.
→No sooner had he finished his speech than the students started cheering.
→Hardly had he finished his speech when the students started cheering.
他刚完成演讲学生们就开始欢呼起来。

【答案】when
考点三 让步状语从句

所有人，无论年老还是年轻，富裕还是贫穷，都一直在尽他们所能帮助灾后需要帮助的人们。
考点四 原因状语从句
知识点 1 because, as, since, for 引导原因状语从句的情况
连词 位置 内涵 语气 回答 why 被强调
because(因为) 主句前或后 直接因果关系 强 能 能

【2024 年全国甲卷】这对作家来说很难，因为结局对读者来说很有分量。
知识点 2 when 引导原因状语从句的情况
when(既然)，也可以引导原因状语从句。
例1. It was foolish of you to take a taxi when you could walk there in five minutes.
既然步行 5 分钟就能到那里，你却去乘出租汽车，真够愚蠢的。
例2. How can they expect to learn anything when they never listen

其他词引导的原因状语从句
seeing that (鉴于，由于)，considering that (考虑到)， in that(因为)，
now that 既然， given that 考虑到， for the reason that 因为，
例1. Now that you are a high school student, you are responsible for what you do.
既然是高中生了，你就要为你的行为负责。
例2. Seeing (that) he refused to help us, there’s no reason that we should now help him.

考虑到她喜欢孩子，我可以肯定教书是最适合她的职业。
例4. I can’t go to the party tonight, in that I have to work late.
我今晚不能去参加聚会，因为我得加班。
考点五 地点状语从句
地点状语从句是指在复合句中作地点状语的从句，表示空间关系，可置于句首、句中或句末，通常由从属连词 where,
wherever 等引导。
例1. We should go where the Party needs us most.
我们应到党最需要我们的地方去。
例2. You are free to go wherever you like.
你愿意去哪里就去哪里。
例3. Where there is a will, there is a way.
有志者，事竟成。
例4. Wherever there is smoke, there is a fire.
无火不生烟。(无风不起浪)
易错辨析：where 引导的定语从句与状语从句。状语从句用于说明谓语动作发生的地点，通常跟在谓语动词（短语）后
面，where 前没有表示地点的先行词，根据这点很容易判断句子是地点状语从句还是定语从句。
例1. You'd better make a mark where you have any question.(状语从句)
你最好在你有问题的地方做个标记。
例2. You'd better make a mark at the place where you have any question.(定语从句)
你最好在有问题的地方做一下标记。
典例．A new school will be built there used to be a factory.
【解析】考查地点状语从句。句意：一所新学校将在过去曾是一家工厂的地方建造。空格处引导地点状语从句，表示“新
学校建在过去曾是一家工厂的地方”，所以用从属连词 where 引导该从句。故填 where。
【答案】where
考点六 结果状语从句
引导结果状语从句的引导词或短语有 so that, so ... that ... , such ... that ... 。
1．结构形式
so＋形容词/副词＋that 从句
{so＋形容词＋a/an＋可数名词单数＋that 从句 ＋可数名词复数so many/few＋ {much/little（少）＋不可数名词 }＋that 从句
{ such＋形容词＋不可数名词such＋形容词＋可数名词复数}＋that 从句such＋a/an＋形容词＋可数名词单数＋that 从句
例1. There was so little food at home that we had to go out to buy some.

例3. He has made such rapid progress that he was praised by his teacher three times a day.
他取得了如此快的进步，以致老师一天表扬了他三次。
易错提醒：so ... that 和 such ... that 的用法：
名前 such，形、副 so，that 从句跟在后；
多多少少必用 so，特别注意是 little；
“小”用 such，“少”用 so。
2．当 so 或 such 置于句首时，主句要用倒装语序。
例 1. So clever a student was he that he was able to work out all the difficult problems.
他是一个如此聪明的学生，以至于他能解决所有的难题。

爆炸的威力如此巨大，以致所有的窗户都被震破了。
3．so/such ... that ... 引导的结果状语从句与 so/such ... as ... 引导的定语从句的区别。

It is such a moving film that we all want to see it.
这是一部如此感人的电影，以至于我们都想去看。
(2) so/such ... as ... 中，as 引导定语从句，as 在从句中作主语或宾语。

这是一部感人的、我们都想看的电影。
典例 1.I developed a strong interest in stage design that I realized I wanted to spend the rest of my life doing it.
【解析】考查连词。句意：我对舞台设计产生了如此强烈的兴趣，以至于我意识到我想用我余生的时间来做这件事。分
析句子结构，本句使用了“such a +名词+that”结构，表示“如此……的……”，符合句意，故填 such。
【答案】such
典例 2（. Calligraphy is so abstract and amazing in Chinese culture it is universally regarded as the most inspiring power
of a person.
【解析】考查结果状语从句。句意：书法是如此抽象和惊人，在中国文化中，它被普遍认为是一个人最鼓舞人心的力量。
本句为 so...that 引导的结果状语从句。故填 that。
【答案】that
考点七 比较状语从句
1．as ... as ...; not so/as ... as ...; the same ... as ... 表示相同程度的比较，肯定句用 as ... as ...，否定句可用 not as ... as 或 not
so ... as。
例 1. He doesn't run so/as fast as Jack (does)．他跑得不如杰克快。
例 2. He works as hard as everyone else (does) in the class.

visit the doctor, providing company and transportation.

as 边……，一边……；随着……”
As time goes on, it's getting warmer and warmer.随着时间的推移，天气变得越来越温暖了。
名师提醒 1. 如果主句表示的是短暂性动作，而从句用延续性动词的进行时表示在一段时间内正在进行的动作时，
when/while/as 可以互换使用。2. when 还可表原因，意为“既然”。

It was three days before he came back.（过了......才......）
过了三天他才会来。
2. since 引导的从句如果用非延续性动词，所表示的动作自从句谓语动词所表示的动作开始时算起；若用延续性动词，所
表示的动作自从句谓语的动作或状态的完成或结束时算起。
It’s three years since he joined the army.(自从......多久了......)
自从他参军已经三年了。
It's two years since we arrived here.
我们到这儿两年了。

It was at eight o'clock that we got home.
正是在八点我们到了家。
4. “It be＋时间点＋when 从句”表示“某事发生在什么时间”，it 指代时间。
It was six o'clock when we got home.

例1. Until you told me I had no idea of it.
直到你告诉我，我才知道这件事。
例2. Not until the film began did she arrive.
直到电影开始她才到。

1. 表示“一 ......就 ......”：as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner ...

既然步行 5 分钟就能到那里，你却去乘出租汽车，真够愚蠢的。
例2. How can they expect to learn anything when they never listen

知识点 3 其它引导原因状语从句的情况
其他词引导的原因状语从句
seeing that (鉴于，由于)，considering that (考虑到)， in that(因为)，
now that 既然， given that 考虑到， for the reason that 因为，
例1. Now that you are a high school student, you are responsible for what you do.

考点五 地点状语从句
地点状语从句是指在复合句中作地点状语的从句，表示空间关系，可置于句首、句中或句末，通常由从属连词 where,
wherever 等引导。
例1. We should go where the Party needs us most.
我们应到党最需要我们的地方去。
例2. You are free to go wherever you like.
你愿意去哪里就去哪里。
例3. Where there is a will, there is a way.

例4. Wherever there is smoke, there is a fire.
无火不生烟。(无风不起浪)
易错辨析：where 引导的定语从句与状语从句。状语从句用于说明谓语动作发生的地点，通常跟在谓语动词（短语）后
面，where 前没有表示地点的先行词，根据这点很容易判断句子是地点状语从句还是定语从句。
例1. You'd better make a mark where you have any question.(状语从句)
你最好在你有问题的地方做个标记。
例2. You'd better make a mark at the place where you have any question.(定语从句)
你最好在有问题的地方做一下标记。
典例．A new school will be built there used to be a factory.
考点六 结果状语从句

1．结构形式
so＋形容词/副词＋that 从句

{ such＋形容词＋不可数名词such＋形容词＋可数名词复数}＋that 从句such＋a/an＋形容词＋可数名词单数＋that 从句

例2. Mike is such an honest worker that we all believe him.
→Mike is so honest a worker that we all believe him.
迈克是一个如此诚实的工人，以至于我们都相信他。
例3. He has made such rapid progress that he was praised by his teacher three times a day.
他取得了如此快的进步，以致老师一天表扬了他三次。
易错提醒：so ... that 和 such ... that 的用法：
名前 such，形、副 so，that 从句跟在后；
多多少少必用 so，特别注意是 little；
“小”用 such，“少”用 so。
2．当 so 或 such 置于句首时，主句要用倒装语序。
例 1. So clever a student was he that he was able to work out all the difficult problems.
他是一个如此聪明的学生，以至于他能解决所有的难题。
例 2. Such was the force of the explosion that all the windows were broken.

3．so/such ... that ... 引导的结果状语从句与 so/such ... as ... 引导的定语从句的区别。

(2) so/such ... as ... 中，as 引导定语从句，as 在从句中作主语或宾语。

例 1. He doesn't run so/as fast as Jack (does)．他跑得不如杰克快。
例 2. He works as hard as everyone else (does) in the class.

2．than 表示不同程度的比较，主句中用形容词或副词的比较级。

他比我们学校的任何一个学生都高。
3．the＋比较级，the＋比较级，表示“越……就越……”

知识点 1 so that 与 in order that 引导目的状语从句的情况
这两个连词都表示“为了，以便”，引导的目的状语从句常与情态动词 can, could，may, might 等连用。in order that 引导的
从句可以置于主句之前或之后，而 so that 引导的从句只能置于主句之后。
例 1.I am studying hard so that/in order that I can enter a famous university.
为了能上一所名牌大学，我一直努力学习。
例 2. In order that we could save time we used the computer.
我们使用计算机是为了节省时间。(此时不可使用 so that)
知识点 2 for fear that 与 in case 引导目的状语从句的情况
for fear that 表示“生怕，以免”，in case 表示“以防”。
例 1.Batteries must be kept in dry places for fear that electricity should leak away.
电池应该放在干燥的地方，以免漏电。
