随机应变，用英语怎么表达

随着科技的进步和人们思想的开放，很多东西都发生了很大的变化，有的时候甚至是质的飞跃，一层不变的东西越来越少，因此不能因循守旧，要与时俱进，特别是有的时候有见机行事或随机应变，哪怕所采取的行动跟实际的计划有冲突。

随机应变表示根据具体的情况灵活办事，因此要随时调整自己来适应具体的情况，我们可以用 adjust 来描述这个调整，意为“适应，习惯”，相当于 adapt，常用于 adjust to sth，adjust to doing sth 或 adjust yourself to sth。Adjust 和 adapt 表示的都是主动去适应环境，例如：

1. adjust:

It took her a while to adjust to living alone.

她过了一段时间才适应独自生活。

You'll quickly adjust yourself to student life.

你将很快适应学生生活。

Her eyes slowly adjusted to the dark.

她的眼睛慢慢适应了黑暗。

2. adapt:

The organisms were forced to adapt in order to survive.

生物被迫适应，以求生存。

It took him a while to adapt himself to his new surroundings.

他过了好一阵子才适应了新环境。

有一个习语可以很形象地用来表达随机应变，它就是 play it by ear，不要把它理解为”用耳朵来玩“，它原先的意思是”即兴发挥”，相当于 improvise，也常用作 play by ear，例如：

Some people can play Chopin's music by ear.

有些人能即兴演奏肖邦的音乐。

George is such a talented piano player! The way he can play pieces by ear after hearing them just once is so impressive!

乔治真是个天才的钢琴演奏家！他只听了一次就可以即兴弹奏乐曲，真是令人印象深刻！

Just because he can play by ear doesn't mean he's a great songwriter.

他能即兴发挥并不意味着他是个伟大的词曲作者。

因此它被用来表示见机行事或随机应变非常贴切，表示在事态发展时作决定，而不是根据之前制定的计划，例如：

I don't have a set schedule, so we'll have to play it by ear.

我没有固定的时间表，所以我们得随机应变。

I am not sure whether my plan will work or not, so let's just play it by ear.

我不确定我的计划是否行得通，所以我们还是随机应变吧。

Jane said that she has to play it by ear because she is not sure where to go tomorrow morning.

简说她得随机应变，因为她不知道明天早上去哪儿。

We can't make a decision yet. Let's just play it by ear.

我们还不能做决定。我们随机应变吧。

会随机应变的人通常让自己的大脑保持冷静，因此可以用 have/keep one's wits about you 来表示随机应变，例如：

Luckily, the teacher kept her wits about her and was able to evacuate all of her students from the burning building.

幸运的是，老师随机应变，把所有的学生从着火的大楼里疏散了出来。

Mountaineering is dangerous, so you need to keep your wits about you.

登山很危险，所以你要保持头脑清醒。

If Jane hadn't kept her wits about her during the fire, things would have been much worse.

如果简在火灾中没有保持机智，情况会更糟。
