Understanding is Only Half The Formula.
理解只是方法的一半。
Understanding is not enough. You must also have a lot of repetition. If you hear a new word only once, you will soon forget it. If you hear it 5 times, you will still probably forget it!
光理解还不够，你必须要进行大量的重复。如果一个新单词你只听过一次，那么很快你就会把它忘记；如果你重复听五次，可能还是会忘记。
You must hear new words and new grammar many times before you will understand them instantly.
在你能够自如的理解新单词和语法规则之前，你必须要反复听上很多次。
How many times is necessary? Most people must hear a new word 30 times to remember it forever. To know a word and instantly understand it, you probably need to hear it 50-100 times!
必须听多少次呢？对于大多人来讲，要想彻底记住一个新词，必须重复30次；要想认识一个新词并立刻明白它的意思，你可能需要听上50至100次。
So, the two most important points are: listen to easier English and listen to each thing many times.
所以，最重要的两点是：听较为容易的材料，并将每一个材料反复听。
