有時，“what'’的這種特點也成為改錯部分的“題眼”。如：
(19)(Some) psychologists believe (what) even a person
(suffers) from amnesia，some (memory) remains in the unconscious．
②whatever，whoever，whichever
上述三個詞的用法與“what”差不多：意義上表示一種強調。但在考題中出現(xiàn)的頻率不及"what”高。
③as，than
本來“ss”和"than"作為關聯(lián)詞只有連接主句和狀語從句的作用，但在托福語法考題中如果符合上面提到的“省略”要求的兩個條件——主句的主語與從句的主語邏輯上相一致；從句以“be'’的適當形式作謂語的“主一系一表”結構或“類主一系一表”結構——這兩個詞除“正?！钡倪B接作用還充當從句的主語：如John’s father was such a stingy man that he seldom spent On his son as much as was necessary．． Mark was delighted tO see his new flat Was larger than was expected．．．
上面的兩個句子中，“as”和“than’分別充當了從句的主語。
三．變性
“變性”是指"after"和“before”所引導的從句在從句的主語與主句的主語一致的時候可以由從句變?yōu)榻樵~(before、after由關聯(lián)詞變成介詞，動名詞短語作介詞賓語)。
如：Before he became the 39th President Of United States，Jimmy Carterhad been the governor Of Georgia．
變成： Before becoming the 39th President Of…
四.變形
“變形”指的是"because"、“since"、“as”和“for'’引導的原因狀語從句在從句的主語與主句的主語一致的時候由從句變成分詞短語。如：
AS she was the first woman to serve in this local court，she enjoyed a greater popularity than her male colleagues。
變成： “Being the first woman tO serve．．．"

(suffers) from amnesia，some (memory) remains in the unconscious．
