    示範例句 · Example

    In science class this week we started learning genetics.

    逐字在科學課這個星期我們開始學習遺傳學。

    「genetics」是一門學科的名字：研究「為什麼小孩會像父母」——這些特徵是怎麼靠基因（gene）一代傳一代的。可以想成 gene（基因）加上 -ics（某某學），就像 physics（物理學）、mathematics（數學）、economics（經濟學）一樣，都是「一整個研究領域」。它是不可數名詞，動詞用單數：Genetics is a science，不說 Genetics are。

core核心畫面

You can picture a set of instructions inside every living thing — instructions that get handed down from parent to child, deciding eye colour, leaf shape, or which illnesses run in a family. Genetics is the field of study that reads those instructions and works out the rules by which they travel.

可以想成：每個生物體內都帶著一份「說明書」，決定眼睛的顏色、葉子的形狀、哪些疾病會在家族裡反覆出現；而這份說明書會從父母傳到子女手上。genetics 就是專門研究這份說明書怎麼寫、怎麼傳下去的那門學問。注意它指的是「研究」本身，不是那些基因——基因是 genes，研究基因的科學才是 genetics。
