2．as soon as, immediately, directly, instantly, the moment, the minute, the instant, no sooner...than..., hardly/scarcely...when...和once(一……就……)，这些从属连词引导的从句都表示从句的动作一发生，主句的动作随即就发生，常译为“一……就……”，从句中用一般时态代替将来时态。
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。
The boy burst into tears immediately he saw his mother.
那男孩一见到他妈妈便放声大哭。
　no sooner... than..., hardly/scarcely....when....的时态搭配：hardly/scarcely后的句子谓语动词应用过去完成时，而than与when引导的句子谓语动词应用一般过去时。此外，当把no sooner和hardly/scarcely提到句首时，应用倒装语序。
He had no sooner finished his speech than the students started cheering.

只有不离河岸太远你才能下去游泳。
三、让步状语从句
1．让步状语从句可由although, though, as, while, even if(though), whenever, whether... or..., no matter who(when, what...)等引导。

尽管有规律的锻炼是很重要的，但是在临近就寝的时候进行锻炼绝不是一个好主意。
However serious a problem you may have, you should gather your courage to face the challenge.
不论你的问题有多严重，你都应该鼓起勇气，接受挑战。

While the Internet is of great help, I don't think it's a good idea to spend too much time on it.

where引导地点状语从句直接修饰动词，而在定语从句中where作为关系副词要跟在表示地点的先行词后面。
When solving the problem a second time, you'd better be more careful where you made a mistake.
＝When solving the problem a second time, you'd better be more careful in the place where you made a mistake.

04重难点突破 状语从句基本知识的综合运用
状语从句考点的解题关键：
1．确定是状语从句
空处所在的句子作整个句子的状语时，应用状语从句的引导词。
2．状语从句的特殊考点要记牢
(1)连词before的意义及句型
It will be＋一段时间＋before ...“多久以后才……”；It won't be＋一段时间＋before ...“用不了多久就……”。
(2)连词since的意义及句型
It is ＋一段时间＋since引导的时间状语从句＝It has been ＋一段时间＋since引导的时间状语从句。
该固定句型意为“自从……以来，已经多长时间了”。
(3)whether ...or ...，疑问词＋-ever，引导让步状语从句。
(4)where引导地点状语从句。
[
　1．when, while, as
(1)when, while, as三者都可以用来引导时间状语从句，意为“当……的时候”。
(2)在when和as引导的从句中，谓语动词既可以是延续性动词也可以是终止性动词，而在while引导的从句中，谓语动词只能是延续性动词。
(3)三者中as引导时间状语从句时，表示主从句动作同时发生或前后紧接着发生，常译为“(正当)……的时候”“随着……”“一边……一边……”等。
2．so ...that ..., such ...that ...
(1)二者都可以引导结果状语从句。so 后中心词为形容词或副词， such后中心词为名词。
(2)若中心词之前有表示数量的many、much、little、few修饰时，只能用so。

DNA analysis reveals two waves of migration
The results of the study, published in the Science Bulletin, revealed two major migration waves in history. In this 1 (pioneer) study, scientists from Fudan University have dug into the ancient DNA of individuals buried in Gansu province, revealing interesting insights into the genetic makeup of Hexi Corridor residents dating back over 12 centuries. The research employed ancient DNA data 2 (explore) human migration along the Hexi Corridor.
The Hexi Corridor was a narrow yet crucial link 3 (connect) the heartland of ancient China to the Western Territory. Characterized by its lofty mountains and deserts, the ancient pathway was dotted with cities 4 (found) along short rivers.
Historical documents attest (证实) to the Hexi Corridor's significance as a crossroads 5 Western and Eastern civilizations mixed through trade, religion and occasional conflicts following the establishment of the Silk Road during the Han Dynasty.
6 technological advances in biology open new avenues for exploration, archaeologists are increasingly drawn to analyzing DNA samples. Led by Wen Shaoqing from Fudan University's Institute of Archaeological Science, the team successfully extracted DNA data 7 the teeth and bones found at two sites near Dunhuang.
The DNA analysis pinpointed two outliers (异常样本) dating to the Wei Dynasty and the Tang. Further examination revealed one had approximately 50 percent western Eurasian ancestry and the other 30 percent, suggesting the individuals were 8 (like) descendants of unions between western Eurasian women and local men.
9 the team concluded was that the genetic mix could be partially attributed to those migrations. Experts said the second major migration period 10 (mark) by a significant shift in the gene pool. Historical records say migration facilitated by Chinese explorer Zhang Qian’ s visit to the Western Territory from 138 BC resulted in the creation of the Silk Road.

【答案】before
【解析】考查时间状语从句。 句意：制作年糕时，糯米粉与水、糖混合，偶尔还会加入油，然后蒸熟，使年糕具有独特的口感。本空引导时间状语从句，表示“在……以前”用before引导。故填before。
3.（2025·福建省宁德市蕉城区宁德第一中学高三一模）Parks can do good for the environment too. Take Beijing’s Central Green Forest Park as an example. The park has reached carbon-neutral (碳中和) it was opened in 2020. This means that though the carbon dioxide is produced from the park’s facilities, the plants there can absorb more to make up.
【答案】since
【解析】考查连词。句意：自2020年开放以来，该公园已实现碳中和。“carbon-neutral”是一种状态，应该是公园开放时达到的，并保持至今，需要用since表示时间的起点。故填since。
04重难点突破 状语从句基本知识的综合运用
状语从句考点的解题关键：
1．确定是状语从句
空处所在的句子作整个句子的状语时，应用状语从句的引导词。
2．状语从句的特殊考点要记牢
(1)连词before的意义及句型
It will be＋一段时间＋before ...“多久以后才……”；It won't be＋一段时间＋before ...“用不了多久就……”。
(2)连词since的意义及句型
It is ＋一段时间＋since引导的时间状语从句＝It has been ＋一段时间＋since引导的时间状语从句。
该固定句型意为“自从……以来，已经多长时间了”。
(3)whether ...or ...，疑问词＋-ever，引导让步状语从句。
(4)where引导地点状语从句。
[
　1．when, while, as
(1)when, while, as三者都可以用来引导时间状语从句，意为“当……的时候”。
(2)在when和as引导的从句中，谓语动词既可以是延续性动词也可以是终止性动词，而在while引导的从句中，谓语动词只能是延续性动词。
(3)三者中as引导时间状语从句时，表示主从句动作同时发生或前后紧接着发生，常译为“(正当)……的时候”“随着……”“一边……一边……”等。
2．so ...that ..., such ...that ...
(1)二者都可以引导结果状语从句。so 后中心词为形容词或副词， such后中心词为名词。
(2)若中心词之前有表示数量的many、much、little、few修饰时，只能用so。

DNA analysis reveals two waves of migration
The results of the study, published in the Science Bulletin, revealed two major migration waves in history. In this 1 (pioneer) study, scientists from Fudan University have dug into the ancient DNA of individuals buried in Gansu province, revealing interesting insights into the genetic makeup of Hexi Corridor residents dating back over 12 centuries. The research employed ancient DNA data 2 (explore) human migration along the Hexi Corridor.
The Hexi Corridor was a narrow yet crucial link 3 (connect) the heartland of ancient China to the Western Territory. Characterized by its lofty mountains and deserts, the ancient pathway was dotted with cities 4 (found) along short rivers.
Historical documents attest (证实) to the Hexi Corridor's significance as a crossroads 5 Western and Eastern civilizations mixed through trade, religion and occasional conflicts following the establishment of the Silk Road during the Han Dynasty.
6 technological advances in biology open new avenues for exploration, archaeologists are increasingly drawn to analyzing DNA samples. Led by Wen Shaoqing from Fudan University's Institute of Archaeological Science, the team successfully extracted DNA data 7 the teeth and bones found at two sites near Dunhuang.
The DNA analysis pinpointed two outliers (异常样本) dating to the Wei Dynasty and the Tang. Further examination revealed one had approximately 50 percent western Eurasian ancestry and the other 30 percent, suggesting the individuals were 8 (like) descendants of unions between western Eurasian women and local men.
9 the team concluded was that the genetic mix could be partially attributed to those migrations. Experts said the second major migration period 10 (mark) by a significant shift in the gene pool. Historical records say migration facilitated by Chinese explorer Zhang Qian’ s visit to the Western Territory from 138 BC resulted in the creation of the Silk Road.
【答案】
1．pioneering 2．to explore 3．connecting 4．founded 5．where 6．As 7．from 8．likely 9．What 10．was marked
【解析】本文是一篇说明文。文章介绍了发表在《科学公报》上的一项研究结果揭示了历史上两次主要的移民浪潮。该研究利用古代DNA数据来探索河西走廊沿线的人类迁徙。
1．考查形容词。句意：在这项开创性的研究中，复旦大学的科学家们深入研究了埋葬在甘肃省的个体的古代DNA，揭示了12世纪前河西走廊居民基因组成的有趣见解。该空需要一个形容词作定语，pioneer为名词兼动词，其形容词pioneering意为“开创性的”符合句意。故填pioneering。
2．考查非谓语动词。句意：该研究利用古代DNA数据来探索河西走廊沿线的人类迁徙。employ something to do something意为“利用…去做…”，由此可知，所给动词explore在句中作目的状语，应使用动词不定式形式。故填to explore。
3．考查非谓语动词。句意：河西走廊是连接古代中国中心地带和西域的一条狭窄而重要的通道。所给动词connect在句中作后置定语，与所修饰名词link为主动关系，应使用其现在分词形式。故填connecting。
4．考查非谓语动词。句意：以高山和沙漠为特征，这条古道上遍布着一些沿着短河流而建立的城市。所给动词found意为“建立”，在句中作后置定语，与所修饰名词cities为被动关系，应使用其过去分词形式。故填founded。
5．考查定语从句。句意：历史文献证明了河西走廊作为东西方文明的十字路口的重要意义，在这里，随着汉朝丝绸之路的建立，东西方文明通过贸易、宗教和偶尔的冲突融合在一起。该空需要一个关系词引导定语从句，并指代先行词crossroads在从句中作地点状语。故填where。
6．考查时间状语从句。句意：随着生物学技术的进步为探索开辟了新的途径，考古学家越来越热衷于分析DNA样本。该空需要一个连接词引导时间状语从句，表示“随着”，应使用连词as,注意句首字母大写。故填As。
7．考查介词。句意：在复旦大学考古科学研究所温少青的带领下，研究小组成功地从敦煌附近两个遗址中发现的牙齿和骨头中提取了DNA数据。介词搭配extract sth. from sth.意为“从…中提取”，符合句意。故填from。
8．考查副词。句意：进一步的研究显示，其中一人有大约50%的西部欧亚血统，另一人有30%的西部欧亚血统，这表明这些人可能是西部欧亚女性和当地男性结合的后代。该空需要一个副词修饰系动词；所给词like为动词，副词likely意为“可能，大概”符合句意。故填likely。
9．考查主语从句。句意：研究小组得出的结论是，基因混合可以部分归因于这些迁徙。该空需要一个连接词引导主语从句，并指代事物在从句中作宾语，应填what，注意句首字母大写。故填What。
10．考查时态语态及主谓一致。句意：专家表示，第二次大迁徙时期的标志是基因库发生了重大变化。该空所给动词mark意为“标志着”在宾语从句中作谓语，句意是基因库的重大变化标志着第二次大迁徙，根据后边的by a significant shift in the gene pool可知，应使用被动语态；结合语境可知，句子陈述的是历史上的事情，应使用一般过去时态；主语核心词period为单数名词，助动词be应使用单数形式。故填was marked。
