1. Concurrent vs. consecutive


“concurrent”是指同时存在或同时发生。

例句:Most patients
need at least twoconcurrenttreatments to be cured of this ailment.

“consecutive”是指在一系列中一个接着一个。

例句:Henry’s research
received funding from the university for the thirdconsecutiveyear.

这2个字基本上非常不同,为了更方便记忆,您可以使用情境记忆法。对concurrent,想象一群人在市场谈话,而consecutive,可以想成在收银台一个人买完单后另一个人接续买单。希望这样有帮助!

2. Comprise vs.
compose


“comprise”是包含的意思,意指全部(包含小部分),当你用comprise这个字的时候,你必须要先提及大物体,然后再说其中包含的不同部分。

例句:My
experimentcomprisesfour parts.

This
packcomprises10 test tubes.

compost是指组成的不同部分。

例句:Four partscomposethis
experiment.

Ten scientistscomposethe committee.

这2个字的差异处是很微妙的,为了更好的记忆它们的不同,可以想成“flowers compose
a bouquet”或“a bouquet
comprises flowers”,composed的另一种用法是“The committee is composed of ten
scientists.”

3. Rational vs.
rationale


“rational”是形容词,值非构建在情感上的逻辑和合理性,既然是形容词,其后通常都会有被形容的名词。

例句:She made arationaldecision
of submitting her paper to a journal whose scope matches her research.

“rationale”则是名词,意指说明某样东西的根本原因。

例句:Can you explain
therationalebehind this experiment?

这2个字因为长得相像,因此常被搞混。

4. Acute vs.
chronic


“acute”指尖锐的,用来表示突然变得严重的疾病或危机。

例句:She was treated with epinephrine
during anacuteasthma attack.

“chronic”是指长期且难治愈的疾病(慢性病)。

例句:The patient suffers from chronic
arthritis.

5. Connote vs. denote

”connote“指某事物的隐含或代表的意思。

例句:This term
connotes different things to different persons.

”denote“指某事物实际上或字面上的意思。

例句:The pi symbol
denotes the number 3.14159.

这2个字义不相同且不可替代使用。
