DNA-The Story of YouPPT，第三部分內(nèi)容：Language notes
1. Except for identical twins, each living thing has its own unique DAN. 除了每個雙胞胎之外，每個生物都有他唯一的DNA。
1)except for除……以外，只是，排除的不是同類，表示對主要部分的肯定和對局部的否定。
Your article is quite good except for several spelling mistakes. 你的文章很好，只是有幾處拼寫錯誤。
except， besides， but 和except for 的區(qū)別
except “除……之外”，排除后面的人或物，而且排除的內(nèi)容和主語往往是同一類。如：We went to see our teacher yesterday except Li Ming. 昨天除了李明以外我們都去看我們的老師了（李明沒去）。
besides “除……之外，還有”，包括該詞后面的人或物。如：We all went to see a film besides Li Ming. 除李明以外我們也都去看電影了（李明去了）。
but““除……之外”,一般用于否定句中，表示”只有……“，如：There is nothing but a pen in the pencil case.鉛筆盒里除了一支鋼筆之外什么也沒有。
except for “除……之外”,后面排除的部分和主語不是同一類人或物.如 :The movie was good except for the ending.這部電影除了結(jié)局之外都很好。
2. From your DNA, scientists can identify not only you but also people related to you. 在你的DNA中，科學(xué)家們不但能鑒別你，而且也能鑒別和你有關(guān)系的人。
1) not only …but also…不但……而且……，連接兩個相同的成分，也可連接兩個分句。連接兩個并列主語時，謂語動詞和臨近主語保持一致；連列兩個并列分句時，not only置于句首，通常用倒裝結(jié)構(gòu)，也就是說，把not only引導(dǎo)的分句中的助動詞或be提到主語前面。
