“Plants harvest energy from the sun and stores it as sugar inside the plant,” said Strano. “What we’re doing is taking some of that stored chemical energy and diverting it into illumination.”
The light,about one-thousandth of the amount needed to read by, is just a start. The technology,Strano said,could one day be used to light interiors or even to turn trees into self-powered street lamps.
老师好,
1.在上面文章段落中,粗体字文字about one-thousandth of the amount needed to read by可否视为与句首the light同位关系的一个名词词组(非限制性);
2.怎样分析名词词组中one-thousandth of the amount哪个是中心词;
3.本句中的needed一词的用法是否是一个形容词(意思近似:necessary or wanted);
4.怎样细分名词性词组about one-thousandth of the amount needed to read by的内部构造
谢谢老师!
The light, about one-thousandth of the amount needed to read by, is just a start.
我这样理解:
首先,比较倾向于把about one-thousandth of the amount needed to read by理解为非限制性定语,从语意理解为对the light的量度衡量,是一种修饰关系,而非等同关系。
其次,词组about one-thousandth of the amount needed to read by的中心词为one-thousandth,副词about解释为其程度状语,介词短语of the amount needed to read by是one-thousandth的后置定语。而the amount needed to read by部分,needed解释为过去分词,是中心名词amount的后置定语,不定式词组to read by解释为名词词组amount needed的后置定语,不定式词组可以理解为省略了逻辑主语people,即为the amount needed (for people) to read by。
仅供参考。
The light【主语】//,about one-thousandth of the amount needed to read by,【同位语】// is【系动词】// just a start【表语】.
参考译文:这种/这些光线,大约是阅读所需数量的千分之一,仅仅只是一个开始。
备注(1):needed to read by 为过去分词短语作后置定语修饰the amount(数量)相当于定语从句which is need to read by 进行阅读所需要的数量。
备注(2):about one-thousandth of the amount needed to read by为同位语用来具体解释说明主语the light(这些光线)的具体数量内容。
备注(3):read by表示的借着…光亮进行阅读。
【1】about短语语法结构分析如下供网友参考
about【前置定语】// one-thousandth【中心词】// of the amount needed to read by【后置定语】//
备注:以上短语,在结构上one-thousandth为中心词,在语义上the amount为中心词。
【2】of短语语法结构分析如下供网友参考
of【介词】//the amount 【宾语】//needed to read by【后置定语】//。
备注needed to read by过去分词作定语,相当于定语从句which is needed to
read by 修饰前面名词the amount即进行阅读所需要的数量。
个人理解,仅供参考。
