Effective 与 Efficient 的正确使用

Effective和efficient的开头拼写相同，发音相似。它们的定义也是相关的。然而，这两个词之间有重要的区别，这使得互换它们是不正确的。

Effective是一个形容词，意思是有效或有用。

• This medicine is very effective at reducing the symptoms of the common cold.

这种药对减轻感冒症状很有效。

Efficient is also an adjective. It means functions without wasting time or some other resource.

efficient也是一个形容词。它是具有不浪费时间或其他资源的功能。

• This car has a fuel-efficient design. It gets 73 miles to the gallon!

这辆车采用了省油设计。一加仑能跑73英里!

Let’s go over the specific ways to use each of these terms so you don’t mix them up.

让我们复习一下这些单词的具体用法，这样你就不会把它们弄混了。

Using Effective in a Sentence

When to use effective: “ effective ”是一个形容词，意思是足以完成一项功能或以一种很好地完成目标的方式做某事，因而是“有效的”。

例如,

• You always yell at your mother when you don’t get your way. However, this never changes anything. It doesn’t seem like an effective way of dealing with conflict.
• Exercise and a healthy diet are proven to be the most effective ways to lose weight.

这个词相当学术，所以在正式场合比在会话中更常用。另一个意思是在特定日期或特定时间生效。

Using Efficient in a Sentence

When to use efficient: efficient 是一个形容词，意思是能够不浪费精力或资源做某事，因而是“高效的”。

例如:

• Copying the book’s text word for word is not an efficient way to study. It would save time and effort if you only copied the most important facts.
• You are doing that the hard way. It will take you too long to carry all your boxes into the house one by one. If you use this cart to wheel multiple boxes to your house at the same time it will be much more efficient.

人们通常用effective和efficient来描述某事。因此，effective是efficient的最佳搭配之一。其他常见的搭配包括节能 energy efficient 和省油 fuel efficient 。

总之，你可以高效做完一件事，这叫efficient, 但你做的结果有很多是错误的，这就不能称作effective。反之亦然，虽然你很effective做完了一件事，结果很正确，但耗时太长，不能称为efficient。
