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) scientists 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 had to be painstakingly removed by scientists
选了D,错了,请教大家,指正。
答案是c
选C.此题考察的是逻辑表达。
注意it所指。正确的逻辑关系是:科学家们掌握了如何合成“生长激素”,这个“生长激素”是从人的尸体中提取的。正确的逻辑际关系中it指代的是“生长激素”,而不是“合成的生长激素”。所以D错。 the growth hormone和synthetic growth hormone的区别。因为科学家得到的样本是“the growth hormone”。
哈哈哈,有意思。
