11.
Before scientists learned how to make a synthetic growth hormone, removing it painstakingly in small amounts from the pituitary glands of human cadavers.

A. scientists learned how to make a synthetic growth hormone, removing it painstakingly
B. scientists had learned about making a synthetic growth hormone, they had to remove it painstakingly
C. scientist learned how to synthesize the growth hormone, it had to be painstakingly removed
D. learning how to make a synthetic growth hormone, scientists had to remove it painstakingly
E. learning how to synthesize the growth hormone, it have to be painstakingly removed by scientists




Ans: C

覺得 (C) 裡 scientist 是不是應該複數(不然可數名詞應該有冠詞),而且用被動! it 作主要子句的主詞,句意沒有 (D) 清楚吧?
(D) before 引導副詞子句,省略主詞 (scientists), be 動詞, 時態也正確.有什麼原因不選它呢?

(C) 選項在PP破解版T2-Q21是複數形scientists

(D) 選項的it會指代到a synthetic growth hormone, 代表須從屍首裡移除人工合成的growth hormone,在邏輯上不合理

文章中劃線的地方有painstakingly, 其為副詞, 選項(A), (B),及(D)會出現雙向修飾的問題, 即是不會知道其應修飾前面的remove或是後面的in small amount, 因此不能選擇此答案
但答案(E)則會出現脫節的問題,因為it代的的growth hormone,而growth hormone並不會learning,所以不選此答案
因此選項(C)會是唯一合理的答案
