enough的位置
一般说来, enough作形容词时,既可以放在它所修饰的名词之前,也可以放在该名词之后,有时意义没有多大区别。但在下列情况下, enough前置或后置,有着语义上的差别和语用上的限制
1.语义差别。
(1)作前置定语的 enough,常常表示数或量刚刚达到为一定的目的所需的最低限度,大致相当于汉语“足够的”、“刚够”;而作为后置定语的 enough,往往表示数或量至少满足或可能超过一定的要求或需求,可表示“许多”或“绰
绰有余”。

例如:
We have enough money for John to buy a house.
我们为约翰买座房子钱也够了。
(含义:我们虽然不是很富有,但是一座房子也还买得起)
试比较下面两例:
They took enough food to last them a week.他们带了足够一星期吃的食物。

They took food enough to last them a week.他们带了那么多食物,足够吃星期的。

第一句意味着他们有意识地带了足够一星期所需的食物。而第二句则意味着他们所带的食物,在说话人看来,比他们所需的数量多得多。可能他们只出去一两天,却带了足够维持一星期的食物。

(2)作前置定语的 enough,其后的不定式往往表示一种目的或目标,而作后置定语的 enough,其后的不定式往往表示结果。
例如:
My ambition is to make enough money to retire at fifty.
我的目标是挣足够的钱,(以便)能在50岁时退休。

September 20, 2018星期四，I set the alarm clock to wake up at five o'clock,Woke up at four fifty,The autumn sun desperately squeezed in from the gap between the curtains,我穿着一件低领的薄外套出去了，我发现清晨佳木斯已经开始看到呼出的白色空气，在月台露出脖子的地方等公共汽车，冷风沿着脊柱直下，我在那里冻结了公共汽车上只有几个困人，没有过去的喧闹这个秋天让人们想着，在现在和将来，我似乎始终无法与我达成共识。我不知道我做不到这个久违的冬天。

2️⃣3️⃣ - "Good morning," said the little prince. "Good morning," said the merchant. This was a merchant who sold pills that had been invented to quench thirst. You need only swallow one pill a week, and you would feel no need of anything to drink. "Why are you selling those?" asked the little prince. "Because they save a tremendous amount of time," said the merchant. "Computations have been made by experts. With these pills, you save fifty-three minutes in every week." "And what do I do with those fifty-three minutes?" "Anything you like..." "As for me," said the little prince to himself, "if I had fifty-three minutes to spend as I liked, I should walk at my leisure toward a spring of fresh water."
