【语篇导读】本文是一篇记叙文,讲述了14岁的Easton LaChappelle 在科学展览上目睹残疾女孩Jenny 的困境后,潜心研发低成本人工假肢,并将设计免费分享,帮助众多残疾儿童的暖心故事。
1. met 句意:在那里,他遇到了Jenny,一个生来就缺少一只手臂的女孩。此处讲述的是过去发生的故事,应用一般过去时,谓语动词 meet 须用过去式 met。
2. children 句意:她昂贵的人工假肢花费了8万美元,而且像她这样的孩子需要一直(更换)新的假肢,因为他们长得很快。child 是可数名词,此处表泛指,故用其复数形式 children。
3. as/because 句意:她昂贵的人工假肢花费了8万美元,而且像她这样的孩子需要一直(更换)新的假肢,因为他们长得很快。空处引导原因状语从句,结合语境可知,用 as 或 because 均符合语境。
4. to help 句意:受此触动,Easton 决定伸出援手。decide to do sth 为固定搭配,意为“决定做某事”,此处用动词不定式 to help 作宾语。
5. an 句意:借助它,他发明了一款由脑信号控制的人工假肢,但起初这款假肢对孩子们来说太重了。arm 是可数名词单数,此处表泛指,且 artificial 发音以元音音素开头,须用不定冠词 an。
6. but 句意:借助它,他发明了一款由脑信号控制的人工假肢,但起初这款假肢对孩子们来说太重了。根据句意可知,空处前后之间为转折关系,应用连词 but 连接。
7. working 句意:Easton 持续研究这款假肢。keep doing sth 为固定搭配,意为“持续做某事”,此处用动名词 working 作宾语。
8. cost 句意:他的设计仅重 0.5 千克,成本约为500 美元!此处 cost 与上文中的 weighed 并列作谓语,cost 的过去式为 cost。
9. for 句意:他将设计免费发布到网上,这样人们就可以下载设计图,用自己的 3D 打印机制作人工假肢了!for free 为固定搭配,意为“免费地”,此处为介词短语作状语。
10. their 句意:他将设计免费发布到网上,这样人们就可以下载设计图,用自己的 3D 打印机制作人工假肢了!此处指代 people,用形容词性物主代词 their 修饰 3-D printers。
