常见笔记缩写及符号:
1. 缩写类
单词的前三四个字母或者是单词的首字母缩略,你要熟练到看到TP,就知道是temperature.
例如:education-edu., Government-gov- , Hypothesis-hypo-, Study-stu-, Research-res-,temperature- TP, Middle age-MA
2.派生词类
派生构词法是英语的主要构词方法。记这类词的时候,可以去掉派生部分(除否定词缀),意思完全足够。省去派生部分可以节省很多时间。
例如:equipment-equip, Variation-vary, Impressionism-impress-press, realism- real, Dating-date, Recycling-recycle, Natural- nature, Circular-circle, Rotation-rotate,familiarize-familiar
3. 专用符号类
一些化学物质的化学符号或者固定的简化方式。
例如:For example-e.g., Carbon dioxide- CO?, hydrogen sulfide- H?S, Carbonic Acid- H?CO?, Sulfuric Acid- H?SO4, Oxygen-O2, hydrogen- H?, Zinc-Zn, Copper-Cu, helium-he, Ammonia-NH3
4.数学符号类
托福听力的题目基本是按照文本顺序出题的,这些数学符号不仅可以让我们记笔记的速度大大加快,也可以帮助我们更快更准地在笔记中定位题目出处,从而能够准确选出正确选项,比如问题是问原因,我们可以从∵或→符号定位;问题问到不同或相同,从符号=,≠,我们也能够很快定位;题目是多选题,我们可以从+号处去定位。
