Answer 1

1.Nitinol is one of the most extraordinary metals＿＿this century.
(A) being discovered (B) to be discovered
答案是 (A) 表已成的事實 (已被發現的)
※說明：
(A) being discovered 在文法上是分詞片語 (被動) ，表已成的事實。
(B) to be discovered 則是不定詞片語 (被動)，表未來。

2. Edgar Allan Poe, ___, was more appreciated and influential in France than
in the United States.
答案是 (B) 主詞同位語 (補充說明主詞是詩人與短篇小說家)
※ 說明：
(A) 由關係代名詞who 引導的形容詞子句，因為前後有『逗點』，是補述用法，較為不妥。
(B) a poet and short story writer, 在這裡是主詞同位語，補充說明主詞。
