Part3 核心句式
1 By learning history, we can understand how things change. 通过学习历史,我们能了解事物是如何演变的。
(1)分析结构: 此句是含方式状语和宾语从句的复合句。we can understand 是主句,主语是we;谓语是can understand;宾语是由how 引导的宾语从句how things change,注意是陈述语序。By learning history 在句中作方式状语,意为“通过学习历史”,其中By 是介词,后接动名词短语作宾语,表示“通过某种方式或手段”。
(2)“by + 动名词结构”表方式、手段,意为“通过做某事”。
宾语从句的引导词how 用于询问方式、过程,译为“如何;怎样”,从句需用陈述语序(主语+谓语+其他)。
例:By practicing every day, she improves her speaking skills. 通过每天练习,她的口语技能不断提高。
By travelling abroad, they can experience how cultures differ around the world. 通过出国旅行,他们能体验世界各地的文化是如何不同的。
2 Visiting a history museum is a great way to learn more about ancient Chinese currency.参观历史博物馆是深入了解中国古代货币的好方法。
(1)分析结构: 句子是主系表结构的简单句,核心结构为动名词短语作主语+ 系动词+ 表语+ 不定式短语作定语。主语是Visiting a history museum 动名词短语,系动词是is,表语是a great way“一种好方法”,名词短语作表语。定语是to learn more about ancient Chinese currency。
(2)单个的动名词或动名词短语作主语的用法:动名词(v. -ing)作主语时,视为第三人称单数,谓语动词用单数形式。
多个动名词(短语)作主语 → 分两种情况当两个或两个以上动名词(短语)用and 连接时,需看语义是否关联:(1) 表“两个独立动作”→ 谓语用复数若动名词描述互不关联的行为,视为复数主语,谓语用复数。
(2)表“同一概念 / 关联动作”→ 谓语用单数
例:Travelling alone is an exciting chance to challenge yourself. 独自旅行是挑战自我的绝佳机会。
Learning a musical instrument is a useful way to develop patience.学习一种乐器是培养耐心的有效方法。
Eating junk food and staying up late are bad for health. 吃垃圾食品和熬夜对健康有害。(两个独立的不良习惯,谓语用复数are。)
Going to bed early and rising early is a healthy habit. 早睡早起是个健康习惯。(“早睡”和“早起”是同一习惯的两个环节,谓语用单数is。)
3 It was first used during the Song Dynasty and made trading much easier.
长难句分析:该句为含并列谓语的简单句。主语为It;and连接两个并列谓语was first used和made,was first used是被动语态,made是主动语态的过去式; made trading much easier中trading是made的宾语,much easier是形容词的比较级作宾语补足语。
4 You’re welcome! Let’s start with these stamps. This one shows that ancient Chinese people used shells as a form of money.
(1)start with 以……开始 to start with 首先;第一
(2)长难句分析:本句是复合句,主语是This one,谓语是shows,后面是that 引导的宾语从句,作shows 的宾语。
5 Here's a great example of what to do with money.
长难句分析:本句为倒装句。Here 开头的倒装句规则:当here/there 置于句首,主语为名词时需倒装,句子用“Here + 系动词+ 主语”结构。“疑问词+ 不定式”作介词of的宾语。
6 She is happy to help teenagers in her hometown with her savings. True happiness can be found not in material things, but in the ability to make a difference in the lives of others.
长难句分析:该句为简单句。主语为True happiness;谓语为can be found,是被动语态;“not... but...”连接并列介词短语in material things和 in the ability,前后形成对比;to make a difference in the lives of others为动词不定式短语作后置定语,修饰ability。
