二、语法和从句分析
1. 定语从句(where / which 引导):he went to the University of Chicago, where he earned his PhD. 中 where 引导定语从句修饰 Chicago;the Yang-Mills theory, which became a foundation of the Standard Model 中 which 引导定语从句修饰 theory。where / which 在从句中分别作地点状语和主语。
2. 被动语态(was done with):Yang's most famous work was donewith Tsung-Dao Lee. 是一般过去时的被动语态(was/were + 过去分词 done),表示“研究是被(与人合作)完成的”,with 引出合作对象。
3. 同级比较 as ... as(与……一样):this theory is almost as important as Einstein's general relativity. 中 as + 原级 + as 表示“与……一样……”,almost 修饰“几乎”。
4. not only ... but also(不仅……而且):Yang's long life was not only a legend of science; it also built a bridge between East and West. 中 not only ... but (also) 连接两个并列分句,强调“不仅……而且”。
5. 同位语 / 头衔:China's first Nobel Prize winner、the Yang-Mills theory 中名词短语直接修饰前面的名词;a world-famous physicist and China's first Nobel Prize winner 作 Yang Chen-Ning 的同位语,补充说明身份。
6. 一般过去时叙事:全文按生平叙述用过去时:Yang began his studies… he went… they won… he became… he helped…,动词 begin→began、go→went、win→won 均为不规则过去式。
7. 过去分词作状语(Born in 1922...):Born in 1922 in Hefei, Anhui, Yang began his studies… 中过去分词短语 Born in... 作状语,相当于 As he was born...,表示背景。
8. 现在分词作伴随状语(opening the door...):…to visit China, opening the door to more exchanges… 中现在分词短语作伴随状语,表示访华同时“打开了交流大门”。
9. 不定式作定语 / 目的状语:one of the first overseas Chinese scholars to visit China 中不定式 to visit 作后置定语修饰 scholars;He worked to restore basic research, raised funds to support students 中不定式作目的状语。
10. 宾语从句(say (that)...):Many scientists say (that) this theory is almost as important as... 中 say 后省略了引导词 that,其后是宾语从句。
