要做好修辭的第一步,就是至少要看出主動詞是否一致 (Subject-Verb Agreement)。
上圖為最基本的 S-V Agreement 的介紹,相信大家基本文法並不陌生。但在 GMAT 當中,有時句子的主詞和動詞之間,會有許多修飾及插入語干擾,而造成判斷錯誤的情形。
Rising inventories, when not accompanied by corresponding increases in sales, possibly leads to production cutbacks that would hamper economic growth.
如題,主詞「Rising inventories」為複數名詞,中間插入了一個修飾語,而將單數動詞「leads」放在修飾語之後,將主詞動詞分開,較不容易察覺主動詞不一致的錯誤。
而正確答案為: Rising inventories, if not accompanied by corresponding increases in sales, can lead to production cutbacks that would hamper economic growth.
將動詞改成正確的形式 「can lead」主動詞符合才是正確答案。
再來一個範例:
Diabetes, together with its serious complications, rank as the nation’s third leading cause of death, only surpassed by heart disease and cancer.
一樣,主詞「Diabetes」為單數名詞,(若看不懂,可由插入句中間的 "its" 判斷),中間插入了一個修飾語,而將複數動詞「rank」放在修飾語之後,為錯誤答案。
而正確答案為: Diabetes, together with its serious complications, ranks as the nation’s third leading cause of death, surpassed only by heart disease and cancer.
將動詞改成正確的形式 「ranks」主動詞符合才是正確答案。
