主要有这几种记忆的方法
理解记忆：费曼学习法提倡的：理解记忆，所有的事情的目的就是让我们理解，把概念变成自己的记忆网络里面的知识，变成自己的语言说出来。
间隔记忆：根据遗忘曲线，通过算法计算在你遗忘90%的时候，提醒你再次记忆，花费的时间最少。这种适合学习新语言的时候记忆单词句子等。
联想记忆：记忆宫殿是最流行的联想记忆，把枯燥的数字和文字等变成图形图形来记忆，有点数字型号变成模拟信号的意思。

The spaced repetition system or spaced repetition algorithm is a vocabulary learning technique that helps you memorize vocabulary for the long-term. The method increases the time intervals between the reviews until you can effortlessly recall the word. For example, you practice the word now, then in an hour, then in 1 day, 2 days, 4 days, etc. until it’s in your long-term memory. The interval increases only if you are able to correctly recall the word.

Spaced Repetition encourages active recall. Active recall is the process of retrieving information from your memory. 

Let me illustrate this. Imagine you want to stop by a bakery in Berlin and want to buy a loaf of bread. Before you even approach the shop, you remember that bread in German is ‘das Brot’. This is an example of an ‘active recall’. You essentially pulled the word out of your memory.

Alternatively, if you approached the shop and saw a sign ‘das Brot’, this would count as a ‘passive recall’. You saw the word and then matched its meaning.

A passive recall is much easier and creates a false sense of progress. However, recognizing a word when you see it doesn’t mean it is in your active memory – that you are able to use it in dynamic, real-life situations, such as a conversation with a colleague. That’s why multiple-choice matching games in some language learning apps are fun but often ineffective.这就是为什么一些语言学习应用程序中的多项选择匹配游戏很有趣，但往往无效。

被动回忆要容易得多，而且会产生错误的进步感。然而，当你看到一个单词时认出它并不意味着它就在你的活动记忆中——你能够在动态的、现实生活中使用它，比如与同事的对话。这就是为什么一些语言学习应用程序中的多项选择匹配游戏很有趣，但往往无效。
