Oxford
would, modal verb
used as the past form of will when reporting what sd has said or thought
She asked if I would help.
used for talking about the result of an event
Hurry up! It would be a shame to miss the beginning of the play.
used for saying what you want to happen
I wish you would be quiet for a moment.
could, modal verb
used as the past tense of can
She said that she couldn't come.
used to show that sth is or might be possible
I could do it now, if you like.
would 似乎多用於表達意願以及有預期事件要發生的情況. could 比較傾向表達可能性. 蠻符合前面christina的說法,"could是用來表可能發生的事,would是應該會發生的事"
the power stations would be made sufficiently safe in the future 言下之意, 安全的核電廠是出自作者的意願,句意並不合理.
依此, the power stations would be made sufficiently safe 言下之意, 安全的核電廠是出自作者的意願,句意並不合理.
另外,ETS經常強調對稱的觀點. but 前後結構要對稱: think that they will be or could be made sufficiently safe 跟 view nuclear power stations as unsafe 要對稱, 因此 they 就對到了 nuclear power stations (think 的對象 vs view 的對象)
另外,OG10有一題,說明would不能用於未來式:
161. A wildlife expert predicts that the reintroduction of the caribou into northern Minnesota would tail if the density of the timber wolf population in that region is more numerous than one wolf for every 39 square miles.
(A) would fail if the density of the timber wolf population in that region is more numerous than
(B) would fail provided the density of the timber wolf population in that region is more than
(C) should fail if the timber wolf density in that region was greater than
(D) will fail if the density of the timber wolf population in that region is greater than
(E) will fail if the timber wolf density in that region were more numerous than
Answer : (D)
D, the best choice, uses a correct sequence of present and future indicative verb forms--predicts, will fail, and is--in the three related clauses. Density, an abstract "mass" noun, is logically construed with greater than. In A and B, would fail disagrees with the other verbs in tense and mood.
