9. 假如人類不浪費那麼多紙，森林也不會那麼快速地縮小面積

(a) If people shouldn’t waste so much paper, surface area of forest wouldn’t be reduced so fast.

(b) If human wouldn’t waste lots of paper, the forest area be reduced fast.

(c) If humans shouldn’t waste so much paper, forest area couldn’t be narrowed quickly.

(d) If humans hadn’t wasted that much papers, the wood area wouldn’t become smaller so fast.

(e) If people didn’t waste much paper, surface area of forest wouldn’t be reduced so quickly.

(f) If people hadn’t wasted so much paper, the area of forest wouldn’t be decreased so soon.

(g) If the man hadn’t wasted such much paper, the forest’s area wouldn’t have reduced rapidly.

(h) If human did not waste a lot of paper, the area of forest would not be decreased rapidly.

重點：

1. 人類浪費紙是不爭的事實，假設部分的動詞一般為「if + v-ed」，不會有情狀助動詞 would、should 之類的，因為情狀助動詞（modal verbs）是在表達猜測、想像、勸告等等不見得會成真的事情。

2. 如果解釋為：人類「從前」不浪費那麼多紙，整句的動詞形式「if + had v-pp…, would/could + have v-pp」。

3. 面積是「area」，有可數形態「the area of + 要測量的平面」，「a/an (total) area of + 測得的面積」，及不可數形態「平面 +測得數據 + in area」這些常用說法。但是，森林不只一處，應該是複數形。

4. 「縮小」一詞要用什麼字表示，要和主詞搭配。以上同學翻譯的句子通通是拿「area」作主詞，那麼「縮小」可以翻成主動語氣的「decrease, become smaller」或被動的「be reduced」。如果以「forest」當主詞，可以搭配「decrease in area」。

5. 在本句中「paper」不可數，搭配的量詞 so much, a lot of, lots of 都可以。

(f) If people hadn’t wasted so much paper, the areas of forests wouldn’t have decreased so soon.

(g) If man hadn’t wasted so much paper, the forest areas wouldn’t have been reduced rapidly.

(h) If humans did not waste a lot of paper, the areas of forests would not decrease rapidly.
