英語詞匯中有很多詞在拼寫上、語義上很相似，如 assure/ensure ， rise/arise/raise ， effect/affect ，但是它們的用法卻迥然不同。這些易混淆的詞構成六級改錯的一個重要錯誤類型，也是比較難的一種類型，這個需要考生在平時的學習過程中注意知識的積累，并多做些總結和歸納，從中找出一些規律。
例 1 His persistence was awarded when the car finally started. 1.__________
句中“ award ”是“頒發，授予(獎賞)”之義，而文中要表達的意思是“汽車終于啟動了，那就是對他堅持不懈精神的回報”，應把 award 改成 reward .
例 2 Deciding how much discomfort and risk we are prepared to put up with in the name of better health is a highly personal matter, not a decision we should remain to doctors 1.__________ alone.
“ remain ”意為“保持，仍然”，是一個表示狀態的動詞，其用法和系動詞“ be ”相似，后面所接成分一般是名詞或形容詞，作表語，而“ leave sth. to sb. ”意思是“把某物留給某人”。本句很明顯是“ leave…to… ”的句型，所以應該把 remain 改為 leave .
例 3 Of course the press means more than newspaper. A vast
amount of magazines are published, aimed at readers 1.__________interested in all sorts of subjects.
因為 amount 表示數量時只與不可數名詞連用，而本句中后面所接名詞為“ magazines ”，是復數名詞，應該使用表示復數形式的 number ，故應該把 amount 改為 number .
例 4 Today, flint has small importance as an industrial product. 1.__________“small”用于表示人或物的體積尺寸，不能修飾抽象名詞 importance ，因此應把 small 改為可以修飾不可數抽象名詞的 little .
