題目的意思是: 因為果汁容易使出生嬰兒細小的胃口填滿,使他們對其他營養食品沒有食欲。所以對未滿24個月的嬰兒來說,喝太多果汁實際上是_________的。
從原因從句可以判斷,主句的填空詞應該是貶義詞。從上面五個答案看,只有B和D入選。B的第一個詞不符題意,故唯一正確的答案是D。
類似的例子還有:
Because of its strength, adhesiveness, and invaluable qualities as a nest-building material, many species of birds ________ silk into their nests.
(A)
smuggle
(B)
jettison
(C)
incorporate
(D)
entice
(E)
dissolve
原因從句列出絲的一系列優點,據此可以判斷主語的填空詞應該是褒義詞。顯然只有C符合這一條件。
有時候,則是通過主語的結果,反推斷出原因從句的填空詞:
Her memoirs are quite unlike those of her predecessors, for she is bold and aggressive where they are _________ and comfortable.
