考点二 非谓语动词作状语
1.不定式作状语
(1)作目的状语,可用so as to/in order to替换,但 so as to一般不可置于句首。
To deal with climate change,we must seize the initiative to do whatever is necessary to protect our environment.
为了应对气候变化,我们必须采取一切必要措施来保护环境。
(2)作结果状语,常表示出乎意料的结果,常用于下列结构中:only to do;enough to do(足够做……);too...to do...(太……而不能……);so/such...as to...(如此……以至于……)等。
Tom took a taxi to the airport,only to find his plane high up in the sky.
汤姆乘出租车去了机场,结果发现他要乘坐的飞机已飞入高空。
(3)作原因状语,常用在“主语+系动词+形容词+to do”结构中。这类形容词有:easy,difficult,hard,cheap,expensive,fit,comfortable,heavy,good,important,impossible,dangerous,surprised,astonished,delighted,disappointed 等。
This machine is very easy to operate. Anybody can learn to use it in a few minutes.
这台机器很容易操作。只需几分钟,任何人都能学会使用它。
[点津] “主语+be+形容词+不定式”结构中,句子的主语和不定式构成逻辑上的动宾关系,且此时不定式通常用主动形式表示被动意义。另外需注意的是在该结构中,不定式中的动词必须是及物动词;若为不及物动词,则要在其后加上适当的介词。
2.分词作状语
非谓语动词作状语时,其逻辑主语通常就是句子的主语。现在分词作状语时,现在分词所表示的动作与句子主语之间构成逻辑上的主动关系。过去分词作状语时,过去分词所表示的动作与句子主语之间构成逻辑上的被动关系。

从塔顶看,南边的山脚下是树的海洋。
Like ancient sailors,birds can find their way using the sun and the stars.
像古代的船员一样,鸟类可以利用太阳和星星找到它们的路。
[点津] 部分过去分词作状语时不表示被动,也不表示完成,而表示一种状态。常见的有:located 坐落于,lost迷路的,seated坐着的,hidden躲着的,lost/absorbed/buried in沉溺于,dressed in穿着,tired of厌烦的,faced with面对着。
Absorbed in painting,John didn't notice evening approaching.
由于专心绘画,约翰没有注意到夜幕正在降临。
3.独立成分作状语
有些分词或不定式短语作状语,其形式的选择不受上下文的影响,称作独立成分。常用的有:generally/frankly/roughly/strictly speaking,talking of,speaking of,judging from/by,taking everything into consideration,compared to/with,to be frank,to tell(you)the truth,to be honest,to make things worse 等。

技法图解
学以致用
1.(2023·新课标Ⅰ卷)To eat one(Xiao long bao),you have to decide whether (bite) a small hole in it first,releasing the steam and risking a spill (溢出),or to put the whole dumpling in your mouth,letting the hot soup explode on your tongue (舌头).
2.(2023·新课标Ⅰ卷)Shanghai may be the (recognize) home of the soup dumpling,but food historians will actually point you to the neighboring ancient canal town of Nanxiang as xiao long bao's birthplace.
3.(2023·新课标Ⅰ卷) No matter where I buy them,though,one steamer basket is rarely enough,yet two seems greedy,and so I am always left (want) more next time.
1.解析 to bite 考查非谓语动词。分析句子结构可知,“whether (bite)a small hole in it first”相当于一个名词短语,在句中作decide的宾语,故填to bite,构成“疑问词+不定式”结构。“疑问词+不定式”结构在句中可作主语、宾语、表语等。
2.解析 recognized 考查非谓语动词。语境表示“上海可能是公认的小笼包之乡”。分析句子结构可知,空前作前置定语,修饰中心词home。recognize与被修饰词home之间构成逻辑上的被动关系,故用过去分词形式recognized。
3.解析 wanting 考查非谓语动词。分析句子结构可知,此处考查“leave +宾语+宾语补足语”结构,表示“使我想着下次多吃点”。该题考查其被动语态的变式结构,在被动语态中,原宾补变成为主补。设空处want与句子主语I构成逻辑上的主动关系,故用现在分词wanting。

[语篇解读] 本文是一篇说明文。本文主要讲述了ChatGPT一经发布就深受欢迎,这也引起了政府立法者的关注,他们质疑它对教育和国家安全的影响。
1.解析 was estimated 动词的时态、语态和主谓一致。分析句子结构可知,空处为谓语。根据时间状语just two months after its launch和常识可知,此处描述的事情发生在过去,应用一般过去时;主语ChatGPT与estimate之间是被动关系;主语ChatGPT是第三人称单数。所以空处填was estimated。
2.解析 fastest 副词。空处修饰空后的形容词growing,应用副词。根据本句中的“in history”可知,此处应用最高级,所以空处填fastest。
3.解析 a 冠词。空后的target是一个可数名词单数,故空处应填冠词。结合语境“但它的受欢迎程度也使它成为监管的目标”可知,此处表泛指,且target的发音以辅音音素开头,所以空处填a。
4.解析 although/though/while 状语从句。结合句意“国会议员Ted Lieu表示,虽然他对聊天机器人感到兴奋,但他也对人工智能感到震惊,尤其是不受限制的人工智能”可知,空处引导让步状语从句,所以填although/though/while。
5.解析 responsibility 名词。分析句子结构可知,空处作介词on的宾语,应用名词,所以填responsibility。
6.解析 using 非谓语动词。分析句子结构可知,空处应用非谓语,与逻辑主语evil leaders,nonstate actors and malicious(怀有恶意的)state actors之间是主谓关系,所以空处填现在分词using。
7.解析 mainly 副词。空处修饰空前的谓语动词,应用副词,所以填mainly。
8.解析 with 介词。此处考查固定表达be consistent with“与……一致的;符合的”。句意:OpenAI在一份声明中说:“每个人对ChatGPT的免费使用是符合民主化信息的原则的。”
9.解析 it 代词。根据句意“我们不想让ChatGPT在学校或其他任何地方被用于误导目的,所以我们正在努力寻找方法来帮助任何人识别由该系统生成的文本”可知,空处缺的意思是“ChatGPT”,故可以用代词it代替。
10.解析 generated 非谓语动词。分析句子结构可知,空处在句中作后置定语。texts与generate之间是逻辑上的动宾关系,故填过去分词generated。
