Because的出題形式通常有三種:第一種是單獨的because;第二種是because of doing;第三種是because sb/ one’s doing。這三種形式的考察點通常是這樣,because的后面一定要接一個完整的句子,because of doing涉及到邏輯主語的問題,而最后一種不是好的表達,可以直接排除掉。如果because后面的從句沒有什么錯誤,那么我們通常是選because引導的從句的選項,不傾向于選because of doing。其實也就是說,通常,because優(yōu)于because of doing優(yōu)于because of sb/ one’s doing。
有很多童鞋不明白,為什么because of sb/ one’s doing一定是錯的。我們都知道SAT喜歡直接的動詞表達,所以對于這種表達方式而言,既出現了sb,也出現了動詞的ing形式,那就不如去掉of,直接說因為某人做了什么事,最直接的主謂表達。
根據上面的解釋,我們來看一下這個題目。A選項because of ignoring..., 可以看出來ignoring的主語應該是physicians, 但是后文句子的主語卻是biofeedback, 所以邏輯主語出問題了,排除掉。B選項是because of one’s doing, 必錯,排除掉。C選項的because of的邏輯主語倒是沒有問題,但是看完之后發(fā)現這句話沒有謂語動詞,所以排除掉。D選項看來看去沒有什么明顯的錯誤,而且也是because引導的原因狀語從句的形式,有直接的主謂賓結構,保留。E選項中沒有because,有非謂語結構——caused by,我們需要找一下它的邏輯主語,應該是medical therapy, 但是medical therapy顯然不是ignoring its potential引起的,邏輯表達有問題,所以排除掉E選項,最終答案為D。
在以后的SAT語法題目中如果出現了because的各種形式,童鞋們可以參考上面的解釋進行選項排除,確定最終答案。
