状语从句语法清单
一、状语从句分类概览
从句类型
常用连接词
功能
时间状语从句
when, while, as, before, after, until, since, as soon as
表示动作发生的时间
条件状语从句
if, unless, as long as, in case 表示条件
原因状语从句
because, since, as, now that
表示原因
让步状语从句
although, though, even if, no matter +疑问词
表示让步转折
目的状语从句
so that, in order that
表示目的
结果状语从句
so...that, such...that 表示结果
方式状语从句
as, as if, as though 表示方式
地点状语从句
where, wherever
表示地点
比较状语从句
than, as...as
表示比较
二、高频考点详解
1. 时间状语从句
when/while/as 区别
when:从句动作可短暂可延续
while:强调主从句动作同时发生,从句动词需延续性
as:强调“一边...一边...”
until 用法
主句谓语是延续性动词→肯定形式(stay until...)
主句谓语是短暂性动词→否定形式(not leave until...)
as soon, immediately, the moment 引导从句表“一...就...”
2. 条件状语从句
“主将从现”原则
If it rains tomorrow, we will cancel the picnic.
主句用将来时,从句用一般现在时
unless = if not
You will fail unless you work harder.
3. 让步状语从句
although/though 不可与but 连用
Although it was raining, we went out. (√)
Although it was raining, but we went out. (×)
as 引导的倒装结构(高频考点)
Child as he is, he knows a lot.
Try as he might, he couldn't solve it.
4. 原因状语从句
because/since/as 区别
because 语气最强,回答why 提问
since/as 语气较弱,表示已知原因
5. 目的与结果状语从句
so that 引导目的从句:常与can/may 连用
Speak loudly so that everyone can hear you.
so...that/such...that 区别
so + adj./adv. + that
such + (a/an) + adj. + n. + that
三、易错点提醒
时态一致性
时间/条件从句中,用一般现在时代替将来时
连接词选择
while 不可替代when 表示“当...时”的所有情况
注意as 既有“当...时”又有“因为”含义
省略现象
当主从句主语一致时,可省略从句主语和be 动词
When (I was) young, I lived in the countryside.
四、备考建议
掌握每个连接词的核心用法,特别是易混词对比
多做长难句分析,练习从句识别
注意写作中的应用,适当使用状语从句提升句子复杂度
真题训练:重点练习包含多个从句的复杂句
五、实战检测(判断正误)
I will call you when I will arrive. (×)
No matter what happens, don't give up. (√)
Although he tried hard, but he failed. (×)
It is such a difficult problem that nobody can solve. (√)
状语从句语法易错点专项突破
一、高频陷阱深度剖析
1. 时态陷阱:“主将从现”的复杂变形
经典错误:
 If it will rain tomorrow, the match will be cancelled.
 If it rains tomorrow, the match will be cancelled.
突破要点:
“主将从现”扩展:主句不仅限于将来时,还包括含将来含义的情态动词或祈使句
 If you see him, tell him to call me. (祈使句)
 If you work hard, you may succeed. (情态动词)
时间从句同样适用:when, as soon as, until 等引导的时间状语从句也要用现在时表将来
I'll call you when I will arrive.
I'll call you when I arrive.
2. 连接词混用陷阱
 when/while/as 
①
的混淆
when:可接短暂性/延续性动词,侧重“时间点”
When he came in, I was reading. (短暂动词)
while:必须接延续性动词,侧重“时间段”
 While I was reading, he came in.
While he came in, I was reading. (× came in 为短暂动作)
as:强调“随着”或“一边...一边”
As time goes by, we grow older.
 because/since/as/for 
②
的语用差异
连词
语气强度
位置
特殊用法
because
最强
可前可后
回答why 提问,可与only/just 连用
since
中等
句首居多
表示已知原因
as
较弱
句首居多
语气较随意
for
最弱
只能后置
表补充说明,非直接原因
易错例:
Because he was tired, so he went to bed early. (重复连词)
Because he was tired, he went to bed early.
He went to bed early because he was tired.
3. “虽然...但是”的中式思维陷阱
必须牢记:
Although/Though 与 but 永远不能同时出现!
Even though 也不能与 but 连用
正确转换:
虽然下雨了,但我们还是去了。
Although it was raining, but we still went.
Although it was raining, we still went.
It was raining, but we still went.
4. 目的与结果状语从句的混淆
核心区别:
so that 表目的:从句常含 can/may/will 等情态动词
He got up early so that he could catch the first bus.
so...that 表结果:主从句是因果关系
He got up so early that he caught the first bus.
实战判断技巧:
看是否有so/such 修饰词 → 有则多为结果状语
看从句是否有情态动词 → 有则多为目的状语
试加“为了”或“以至于”翻译 → 哪个通顺选哪个
5. unless 的“反向思维”陷阱
unless = if not,但并非所有if not 都能替换:
You'll fail unless you work hard. (= if you don't work hard)
I'll be surprised unless he wins. (除非他赢?逻辑不通)
关键点: unless 引导的从句必须是“排除某条件后主句会发生”的情况
二、特殊句型易错点
1. not...until 的强调句变形
原句: I didn't realize it until he told me.
强调句变形易错:
It was until he told me that I realized it. (×)
It was not until he told me that I realized it. (√)
记忆口诀: “not 前移,that 跟随,until 从句中间嵌”
2. as 引导让步状语从句的倒装
必须倒装的结构:
形容词/名词/副词 + as + 主语 + 谓语
Young as he is, he knows a lot. (形容词)
Child as he is, he knows a lot. (名词,注意不加冠词)
Hard as he tried, he failed. (副词)
常见错误:
As he is young, but he knows a lot. (as 在此不表让步)
A child as he is, he knows a lot. (名词前不加冠词)
3. no matter + 疑问词 与疑问词-ever 的区别
类型
例句
语法功能
no matter + 疑问词
No matter what he says, I won't believe him. 只引导让步状语从句
疑问词-ever
Whatever he says is interesting.
可引导名词性从句和让步状语从句
易错点: No matter what 不能作主语或宾语
No matter what he said surprised me. (×)
Whatever he said surprised me. (√)
三、省略现象的精准把握
从句省略的条件:
主从句主语一致
从句谓语含be 动词
省略后为“连接词 + 形容词/分词/名词”
正确省略:
When (you are) in Rome, do as the Romans do.
If (it is) necessary, I'll help you.
错误省略:
Because ill, he didn't come. (缺少be 动词原形)
Because he was ill, he didn't come.
四、实战纠错训练
找出错误并改正:
1. He won't go to bed until his mother will come back.
2. No matter how hard is it, I will try my best.
3. Although he is poor, but he is honest.
4. I got up early so that I didn't miss the train.
5. Unless it rains, the game will be held outdoor.
答案与解析:
1. will come → comes (时间状语从句用现在时)
2. is it → it is (从句要用陈述语序)
3. 去掉but (although 和but 不能连用)
4. so that → so...that (从句无情态动词,表结果而非目的)
5. 正确 (unless = if not,逻辑合理)
五、避坑口诀总结
时态原则:“主将从不从将,现在时代将来”
连词搭配:“虽然但是不同现,因为所以不并存”
unless 用法:“unless 等于if not,逻辑不通不要换”
倒装结构:“as 表让步要倒装,名词前面无冠词”
目的结果:“目的有情态,结果有so/such”
状语从句语法临考抢分技巧
一、考场快速识别三步法
第一步:看选项特征,预判考点
选项全是连词 → 考从句类型判断
when/while/before/after → 时间状语从句
if/unless → 条件状语从句
although/though → 让步状语从句
because/since → 原因状语从句
选项含so that/so...that → 考目的vs 结果辨析
选项含as → 特别注意多义判断(当...时/因为/正如/虽然)
第二步:找主句时态,用时态规则排除
主句是将来时或祈使句 → 在if/when/until/as soon as 等引导的时间/条件从句中,直接排除含will/would 的
选项
 If it rains tomorrow, we'll stay home.
主句是过去时 → 检查从句时态逻辑一致性
第三步:分析逻辑关系,用关键词印证
圈出题干中隐含逻辑的关键词:
still/yet → 前面很可能需要although/though
or/or else → 前面可能是unless(= if not)
too/enough → 后面可能需要to do 不定式(不是状语从句)
二、四大秒杀技巧(直接排除错误选项)
技巧1:“成对连词”必杀技
以下搭配永远错误,见即排除:
Although/Though...but... (虽热...但是)
Because...so... (因为...所以)
The reason...because... (reason 后接why/that)
口诀:虽然但是不同现,因为所以不共存。
技巧2:while 的“延续性”判断
看到while,立即检查从句动词:
如果是延续性动词(be, stay, study)→ 可能正确
如果是短暂性动词(come, leave, finish)→ 直接排除
While I was studying, he called.
While he came in, I was studying. (应改为When)
技巧3:unless 的“反向验证”
将unless 替换为if not,看逻辑是否通顺:
原句:You will fail unless you work hard.
验证:You will fail if you do not work hard.  
✓逻辑通顺 → 正确
技巧4:so that 与so...that 的“情态动词”区分
从句中有can/may/will 等情态动词 → 选so that(目的)
从句中无情态动词,且有“如此...以至于”之意 → 选so...that(结果)
快速判断:试着在从句前加“为了”,通顺则为目的状语从句。
三、特殊句型快速破解
1. As 倒装句的识别标志
看到选项或题干中出现:
形容词/名词/副词 + as + 主语 + 谓语
动词原形 + as + 主语 + 情态动词
→ 这是as 引导的让步状语从句,意为“虽然”,直接选择或确认
例:Hard as he tried, he failed. (虽然他很努力)
2. Not until 强调句的固定结构
看到“It was...that...”结构,且涉及“直到...才”,只有一种正确形式:
It was not until + 时间状语 + that + 主句
不是:It was until...that...(缺少not)
3. No matter wh- 与 wh-ever 的互换
在状语从句中:No matter what = Whatever; No matter where = Wherever 等,可互换
在主语/宾语位置:只能用wh-ever,不能用No matter wh-
Whatever you say is wrong. (主语位置)
No matter what you say is wrong.
四、临场应急策略
选项概率分析
根据近五年高考统计:
考查频率最高:时间(30%)> 条件(25%)> 让步(20%)
when/while/as 辨析几乎每年必考
although/though 与but 连用是最常见陷阱
两选一纠结时的取舍原则
选“常见”不选“生僻”:在意思相近时,选大纲内高频连词
表“因为”:because > since > as > for
表“虽然”:although/though > even if
选“具体”不选“宽泛”:
when(具体时间点)优于while(时间段)
because(直接原因)优于since(已知原因)
语法优先逻辑:如果语法规则明确(如时态),即使翻译上有点别扭,也按语法规则选
五、考前速记口诀
状语从句抢分口诀
一看选项判类型,二看时态主将现。
虽然但是不同句,因为所以不见面。
while 接续不接短,unless 否定逻辑验。
目的有情态,结果有so/such。
as 倒装要让步,not until 固定结构记心间。
选项纠结看统计,高频常见是首选。
状语从句语法必练题型
一、单项选择(经典陷阱题)
1. 时态考点(主将从现)
— I’ll lend you my camera ____ you promise to return it by Friday.
A. unless B. as long as C. even if D. so that
解析: B。本题考查条件状语从句。主句“I’ll lend”为将来时,从句需用一般现在时表将来。as long as 意
为“只要”,符合句意“只要你答应周五前归还”。unless(除非)逻辑不通;even if(即使)和so that
(为了)不符合语境。
2. 连接词辨析(when/while/as)
— ____ the manager is away on business, his assistant will be in charge.
A. Even if B. As if C. While D. Until
解析: C。本题考查时间状语从句连接词辨析。句意为“经理出差期间,他的助理将负责”。此处强调
“在一段时间内”,且从句动词“is away”为延续性状态,故用While。When 也可表示时间段,但while 更
强调对比或持续。As 表“随着”或“一边…一边”,不符合。
3. 让步状语从句(although/but 陷阱)
— ____ it was raining heavily, they decided to set off as planned.
A. Since B. Unless C. Although D. If
解析: C。本题考查让步状语从句。句意为“虽然雨下得很大,他们还是决定按计划出发”。主从句间存
在转折关系,故选Although。A(既然)、B(除非)、D(如果)均不符合逻辑。陷阱提示: 本题主句
前绝对不可加but。
4. 目的与结果从句辨析
— He spoke ____ slowly that everyone could understand him clearly.
A. so B. such C. enough D. too
解析: A。本题考查结果状语从句结构“so...that...”。so 修饰形容词或副词(slowly),such 修饰名词。句
意为“ 他说得如此慢,以至于每个人都听懂了” 。could understand 是结果,不是目的(目的常
用can/may)。
5. unless 逻辑验证
— You won’t pass the exam ____ you start working hard right now.
A. as if B. in case C. unless D. when
解析: C。本题考查条件状语从句。句意为“除非你现在开始努力学习,否则你考试不会及格”。unless 
= if not,代入验证:“如果你不现在开始努力,你考试不会及格”,逻辑通顺。in case(以防)和as if
(好像)不符合句意。
二、单句改错(识别并改正错误)
1. 错误: If it will be fine tomorrow, we’ll go hiking.
改正: will be → is
考点: 时间/条件状语从句中,用一般现在时表示将来。
2. 错误: Although he is very young, but he has read many classics.
改正: 去掉 but
考点: Although/Though 与 but 不能连用。
3. 错误: He got up early so that he caught the first bus.
改正: so that → so...that 或 so that he could catch
考点: so that 引导目的状语从句时,从句应包含情态动词(can, could, may 等)。原句中“caught”是事实
结果,应改为“so early that he caught”(结果)或“so that he could catch”(目的)。
4. 错误: No matter what he says it doesn’t affect me.
改正: No matter what → Whatever
考点: “No matter +疑问词”只能引导让步状语从句,不能作主语。此处需要主语,故用Whatever (= 
Anything that)。
5. 错误: I didn’t realize my mistake until my teacher has pointed it out.
改正: has pointed → pointed
考点: until 引导的时间状语从句,其时态应与主句保持逻辑一致。主句为一般过去时(didn’t realize),
从句也应用一般过去时。
三、语法填空(综合运用)
真题模拟:
When you try something new, it’s normal to feel nervous. In fact, a little stress can be helpful 1 it pushes you to 
prepare better. 2 (remember), you won’t succeed unless you dare to take the first step. The process may be tough, 
3 the sense of achievement you get in the end is worth all the effort. Many successful people failed repeatedly 4 
they finally made it. So, 5 you face a challenge, just tell yourself, “I can do this!”
答案与解析:
1. because / as / since。考查原因状语从句。后句“it pushes you...”是前句“有帮助”的原因。
2. Remember。考查时间/条件状语从句的省略。原句为“When/If you remember”,当主从句主语一致且从
句谓语含be 动词时,可省略“you are”。
3. but。考查让步关系的连词。前后句是转折关系,“过程艰难,但成就感值得”。陷阱提示: 前面没有
Although,这里直接用but 连接两个并列句。
4. before。考查时间状语从句。句意为“许多成功者在最终成功之前反复失败过”。
5. when / whenever。考查时间状语从句。句意为“所以,当你/无论何时面对挑战时...”。
四、句型转换(掌握高级表达)
1. 合并句子(使用状语从句)
原句:He practiced very hard. He wanted to win the competition.
合并:He practiced very hard so that he could win the competition.
考点: 用so that 引导目的状语从句合并句子。
2. 改写句子(使用as 引导的让步倒装句)
原句:Although he is a child, he knows a lot about world history.
改写:Child as he is, he knows a lot about world history.
考点: as 引导让步状语从句需倒装:名词/形容词/副词/动词原形 + as + 主语 + 谓语。
3. 转换为强调句(使用It was not until...)
原句:I didn’t realize the importance of health until I fell ill.
转换:It was not until I fell ill that I realized the importance of health.
考点: not until 的强调句型固定结构。
备考建议
限时训练:15 分钟内完成以上所有题型,模拟考场节奏。
错题归因:对错题不要只记答案,要明确标注考点(如:“主将从现遗忘”、“although-but 连用”)。
语境意识:遇到长难句,先划出主句和从句,判断逻辑关系,再选择连词。
口诀应用:做题时心中默念口诀(如“虽然但是不同现”),形成条件反射。
状语从句语法综合小测
一、单项选择题(每题2 分,共30 分)
1. —When will you come to see me, Dad?
—I will go to see you when you ______ the training course.
A. will finish  B. finish  C. finished  D. are finishing
答案:B
解析:本题考察时间状语从句的时态呼应。when 引导时间状语从句时,主句用一般将来时(will go),从
句需用一般现在时表示将来含义,即“主将从现”。A 选项will finish 为将来时,不能用于时间状语从句表
将来;C 选项finished 为过去时,时态不符;D 选项are finishing 为现在进行时,表正在进行,不符合句意。
核心考点:时间状语从句(when/as/while/before/after 等引导)的“主将从现”原则。
2. You won’t pass the exam ______ you study hard.
A. if  B. unless  C. because  D. when
答案:B
解析:本题考察条件状语从句的连词辨析。句意“除非你努力学习,否则你不会通过考试”。unless 意为
“除非,如果不”,相当于if not,符合句意;A 选项if(如果),代入句意逻辑相反;C 选项because(因
为),引导原因状语从句,逻辑不符;D 选项when(当……时),引导时间状语从句,语义不符。易错点:
区分unless 和if not 的用法,unless 不能与not 连用(避免出现unless you don’t study 的错误)。
3. He didn’t go to school yesterday ______ he was seriously ill.
A. because  B. so  C. though  D. if
答案:A
解析:本题考察原因状语从句的连词辨析。句意“他昨天没去上学,因为他病得很重”。because 引导原因
状语从句,表直接原因,符合句意;B 选项so(所以),表结果,不能引导原因状语从句(注意:because
和so 不能同时出现在一个句子中);C 选项though(虽然),引导让步状语从句,逻辑不符;D 选项if
(如果),引导条件状语从句,语义不符。核心考点:because(直接原因)与since/as(间接原因,“既
然”)的区别。4. ______ it rained heavily, they still went on with their work.
A. Because  B. Even though  C. As  D. Since
答案:B
解析:本题考察让步状语从句的连词辨析。句意“尽管雨下得很大,他们仍然继续工作”。even 
though/though 意为“虽然,尽管”,引导让步状语从句,符合句意;A、C、D 选项均引导原因状语从句
(because 表直接原因,as/since 表“既然”),逻辑不符。易错点:even though 可与though 互换,even if
表“即使”(假设的让步),本题为真实存在的让步(雨确实下得大),用even though 更贴切。
5. She spoke slowly ______ everyone could understand her.(  )
A. so that  B. because  C. although  D. if
答案:A
解析:本题考察目的状语从句的连词辨析。句意“她说话很慢,以便每个人都能听懂她”。so that 意为
“以便,为了”,引导目的状语从句,从句常含can/could/will 等情态动词,符合句意;B 选项because(因
为),表原因;C 选项although(虽然),表让步;D 选项if(如果),表条件,均不符合语义。区分考点:
so that 引导目的状语从句(表“为了”),so…that…引导结果状语从句(表“如此……以至于……”),
本题无形容词/副词,故为目的状语从句。
6. The film is ______ moving ______ many people cried.
A. too; to  B. so; that  C. such; that  D. enough; to
答案:B
解析:本题考察结果状语从句的固定结构辨析。句意“这部电影如此感人,以至于很多人都哭了”。
so+形容词/副词+that…(如此……以至于……),moving 为形容词,符合结构;A 选项too+形容词/副词
+to do(太……而不能……),to 后接动词原形,不能接句子;C 选项such+(a/an)+形容词+名词
+that…,本题无名词,故不适用;D 选项enough+形容词/副词+to do(足够……去做……),to 后接动词
原形,不能接句子。易错点:区分so 和such 的用法,核心看形容词后是否有名词。
7. I will call you ______ I arrive in Beijing.
A. as soon as  B. as long as  C. even if  D. so that
答案:A
解析:本题考察时间状语从句的连词辨析。句意“我一到北京就给你打电话”。as soon as 意为“一……
就……”,引导时间状语从句,符合句意;B 选项as long as(只要),引导条件状语从句;C 选项even if
(即使),引导让步状语从句;D 选项so that(以便),引导目的状语从句,均不符合语义。核心考点:
as soon as 引导的时间状语从句,也遵循“主将从现”原则(本题主句will call 为将来时,从句arrive 为一
般现在时)。
8. ______ you are right, I won’t agree with you.
A. Even if  B. Because  C. If  D. As
答案:A
解析:本题考察让步状语从句的连词辨析。句意“即使你是对的,我也不会同意你”。even if(即使),
引导让步状语从句,表假设的让步,符合句意;B 选项because(因为),表原因;C 选项if(如果),表
条件;D 选项as(因为/当……时),均不符合逻辑。易错点:even if 与though 的区别,even if 可用于假设
性让步(本题“你是对的”可能是假设),though 多用于真实让步。
9. He studies harder ______ he can get good grades in the college entrance exam.
A. in order to  B. so that  C. because  D. as if
答案:B
解析:本题考察目的状语从句的连词辨析。句意“他学习更努力,为了能在高考中取得好成绩”。so that
引导目的状语从句,后接完整句子,符合句意;A 选项in order to(为了),后接动词原形,不能接句子;
C 选项because(因为),表原因;D 选项as if(好像),引导方式状语从句,均不符合语义。区分考点:
in order to+动词原形,so that+句子,二者均表目的。
10. —Do you know when he will come back?
—I don’t know, but I will tell you ______ he comes back.
A. when  B. if  C. as soon as  D. unless
答案:C
解析:本题考察时间状语从句的连词辨析。句意“——你知道他什么时候回来吗?——我不知道,但他一
回来我就告诉你”。as soon as(一……就……),引导时间状语从句,符合句意;A 选项when(当……
时),语义不如as soon as 贴切(侧重“立刻、马上”);B 选项if(如果/是否),表条件或疑问;D 选项
unless(除非),表条件,均不符合语义。核心考点:as soon as 引导的时间状语从句,时态遵循“主将从
现”。
11. The more you practice speaking English, ______ you will speak it.
A. better  B. the better  C. best  D. the best
答案:B
解析:本题考察比较状语从句的固定结构。句意“你练习英语口语越多,说得就会越好”。the+比较级,
the+比较级(越……,就越……),为固定结构;A 选项better 为比较级,缺少the;C、D 选项为最高级,
不符合结构。易错点:注意比较级前的the 不能省略,且前后均需用比较级形式。
12. He didn’t go out to play ______ he had finished his homework.
A. until  B. when  C. because  D. if
答案:A
解析:本题考察时间状语从句的连词辨析。句意“他直到做完作业才出去玩”。not…until…(直到……
才……),为固定搭配,符合句意;B 选项when(当……时),语义不符;C 选项because(因为),表
原因;D 选项if(如果),表条件,均不符合语义。核心考点:not…until…的用法,until 引导时间状语从
句,主句为否定句时,表“直到……才……”。
13. ______ the weather is bad, we will still go for a picnic.
A. Because  B. Even if  C. If  D. As long as
答案:B
解析:本题考察让步状语从句的连词辨析。句意“即使天气不好,我们仍然会去野餐”。even if(即使),
引导让步状语从句,符合句意;A 选项because(因为),表原因;C 选项if(如果),表条件;D 选项as 
long as(只要),表条件,均不符合逻辑。易错点:even if 可与even though 互换,引导让步状语从句,常
与still/yet 连用。
14. She looks ______ she hasn’t slept for a long time.
A. as if  B. because  C. so that  D. even if
答案:A
解析:本题考察方式状语从句的连词辨析。句意“她看起来好像很久没睡觉了”。as if(好像,似乎),
引导方式状语从句,符合句意;B 选项because(因为),表原因;C 选项so that(以便/以至于),表目的
或结果;D 选项even if(即使),表让步,均不符合语义。核心考点:as if 引导的从句,常用虚拟语气
(本题为真实语气,表“看起来确实如此”)。
15. You can borrow my book ______ you promise to return it on time.
A. as long as  B. unless  C. because  D. even if
答案:A
解析:本题考察条件状语从句的连词辨析。句意“只要你答应按时归还,你就可以借我的书”。as long as
(只要),引导条件状语从句,符合句意;B 选项unless(除非),表否定条件(相当于if not),语义相
反;C 选项because(因为),表原因;D 选项even if(即使),表让步,均不符合语义。区分考点:as 
long as 与if 的区别,as long as 侧重“前提条件”,语气比if 更强烈。
二、句型转换(每题4 分,共20 分)
要求:根据句意,用合适的状语从句连词改写句子,保持句意不变,每空一词(含缩写)。
1. He got up early. He wanted to catch the first bus.(改为目的状语从句)
He got up early ______ ______ he could catch the first bus.
答案:so that
解析:本题考察目的状语从句的改写。原句句意“他起得很早,他想赶上第一班车”,改写后用so that 引
导目的状语从句,表“为了能赶上第一班车”,so that 后接完整句子,符合目的状语从句的用法。易错点:
不能用in order to(后接动词原形),本题要求改写为从句,需用so that。
2. You study hard. You will pass the exam.(改为条件状语从句)
______ you study hard, you will pass the exam.
答案:If/As long as
解析:本题考察条件状语从句的改写。原句句意“你努力学习,你就会通过考试”,改写后用if(如果)
或as long as(只要)引导条件状语从句,均符合句意,且遵循“主将从现”原则(主句will pass 为将来时,
从句study 为一般现在时)。核心考点:if 和as long as 均可引导条件状语从句,可互换(as long as 语气更
强)。3. The rain was heavy. We couldn’t go out.(改为结果状语从句)
The rain was ______ heavy ______ we couldn’t go out.
答案:so; that
解析:本题考察结果状语从句的固定结构。原句句意“雨很大,我们不能出去”,改写后用so+形容词
(heavy)+that…引导结果状语从句,表“如此大的雨,以至于我们不能出去”。易错点:区分so 和
such,本题heavy 为形容词,无名词,故用so…that…,不用such…that…(such 后需接名词)。
4. He finished his homework. Then he went to bed.(改为时间状语从句)
He went to bed ______ he finished his homework.
答案:after
解析:本题考察时间状语从句的连词用法。原句句意“他做完了作业,然后去睡觉了”,改写后用after
(在……之后)引导时间状语从句,表动作发生的先后顺序(先完成作业,后去睡觉)。补充考点:也可
用as soon as(一做完作业就去睡觉),但结合原句“then”(然后),after 更贴合语义(侧重“之后”,
无“立刻”含义)。5. She is young. She can speak three languages.(改为让步状语从句)
______ she is young, she can speak three languages.
答案:Though/Although/Even though
解析:本题考察让步状语从句的连词用法。原句句意“她很年轻,但她能说三种语言”,前后为转折让步
关系,用though/although/even though (虽然,尽管)引导让步状语从句,均符合句意。易错点:
though/although 不能与but 连用,本题改写后,主句无需加but(让步状语从句本身含转折含义)。
