下面小站為大傢詳細講解一下這兩個分類在新 SAT 語法考試中的考試情況，並看一些混淆詞匯的真題幫助大傢更好的理解。
一、拼寫或發音相近的詞
例如：censor sensor
1、censor is to prohibit free expression. 抑制
例句：It is wrong to censor the press.
2、A sensor is something that interprets stimulation. 傳感器
例句：Our security system includes a motion sensor.
二、物主限定詞
另一易混淆詞就是物主限定詞瞭，比如 your, their, its 等。這類詞雖然看起來非常簡單，但是如果不註意的話，考試時它們也會常常 " 以假亂真 "，導致錯選。針對這兩種情況，用一道真題來給大傢解析：
例題：Among all music formats, only online streaming and vinyl saw growth in 2014. Both digital downloads and CD sales declined. The resurgence of vinyl, a music format many have believed to be all but extinct, is surprising. The reason for its resurgence depends on one ’ s ( 1 ) prospective. Some fans of vinyl believe that music simply sounds better on a record, but since many vinyl albums are reproduced from CDs, this is unlikely to be true. In truth, the resurgence of vinyl is likely about nostalgia and identity, as vinyl allows people to own and display ( 2 ) there musical tastes.
1. A ) NO CHANGE
B ) prospect
C ) persecute
D ) perspective
2. A ) NO CHANGE
B ) they ’ re
C ) their
D ) your
解析：第一題中考察的四個單詞 ( prospective，prospect，persecute，perspective ) 的發音是不是很像呢 ? 根據原文句子的語境，原文是說 vinyl ( 黑膠唱片 ) 這種音樂的回歸是有點 " 蹊蹺 "，它回歸的原因要視音樂愛好者的個人觀點而定。認真比較選項中三個發音相近的單詞，隻有 D 選項是表示 "point of view"，最能 make contextual sense.
第二題考察的是物主限定詞的用法，根據上下文語境，作者在這裡想表達 "vinyl 可以讓人們擁有並展示個人音樂品味 "，最佳答案應該是 C 選項中的 plural possessive pronoun ( 物主代詞 ) their.
