1. 这是个什么词?

词:optimal

英英释义:the best or most suitable for a particular purpose or in a particular situation

例句:Although some British universities require a minimum IELTS score of 6.5 for admission, 7.5 would be optimal for those who want to have an edge.

2. 为什么选这个词?

“optimal”是形容词,意思是“最优的、最理想的”。有时它还可以拼写作 optimum,意思和用法不变。一般 optimal 可以用来形容时机、条件、解决方案、结果等,常可以替换 best 和 ideal。这个词在《经济学人》中出现的频率非常高,我们在口语和写作中都可以使用。下面来看几个例子。

虽然有的英国大学录取要求是雅思 6.5 分,但 7.5 分更容易被录取,我们就可以说:

Although some British universities require a minimum IELTS score of 6.5 for admission, 7.5 would be optimal for those who want to have an edge.

有些户型不是方方正正的,实用面积有限,如果室内设计巧妙,充分利用了空间,我们就可以说:

This interior design makes the optimal use of the available space.

最优的解决方案应该是用最少的预算和时间完成项目,就可以说:

The optimal solution is to use as little budget and time as possible to get the project done.

《经济学人》最近在一篇应对气候变化的文章中就用到了 optimal:

A carbon price is indeed the optimal way to reduce pollution, but getting people to pay for carbon has been a vote-loser in America and Europe.

另一篇关于新能源的《经济学人》文章中也出现了 optimal:

SkySails’ kite is launched, like a recreational kite, into the wind at ground level. Then, as the kite is pulled up by the wind while being manipulated to travel in a series of figures-of-eight in order to achieve a constant, optimal speed, the tether uncoils, spinning the drum.

《经济学人》在写美国对含糖饮料征税的文章中多次用到了 optimal, 比如下面两句:

They compute an optimal tax rate of 1-2 cents per ounce of soft drink in America. Taking this into account they reckon that the optimal rate for cities is 0.5 cents, although a more efficient system would be a state or national tax to control America’s sugar rush.

3. 怎样学会使用这个词?

1)翻译下面的句子: 一些应用更多关心的是最佳用户体验,而不是不顾一切的增长。

Some apps are more concerned about ensuring optimal user experience than pursuing relentless growth.

(参考翻译:Some apps are more concerned about ensuring optimal user experience than pursuing relentless growth.)

2)结合自己的生活、学习、工作、兴趣等,想象在什么语境下会用到这个表达。先简要描述这个场景,再造句。

例子: 按时吃药以达到最佳的疗效。

场景:Take medicine duly to achieve the optimal efficacy.
