　　A

　　When it comes to learning a foreign language, many people wonder if they will be able to memorize enough vocabulary. But this question never happens about their mother tongue, and yet, it was a foreign language once. However, among all the questions that new parents ask, no doctor has ever heard: "Will my baby be able to learn my language？" Be honest, do you know all the words of your mother tongue? The answer is："No"．

　　New words, and new ways of using old words, appear every day. Twenty years ago, who would have been able to understand a sentence like this："Click here to download your digital book"？ Nobody. You never stop learning new vocabulary and you never know how long you will need it.

　　Sometimes,_you_have_the_word_on_the_tip_of_your_tongue_...and_it_sticks_there! But you do know this phenomenon (现象) and don't think that it is because of a bad memory. You should not give this phenomenon more importance in the language you are learning than in your mother tongue.

　　You need to learn only 2,000 or so basic words to be able to create any phrase you need. You can't avoid some work in order to learn these necessary words and all the more if you want to learn quickly. And before you consider buying into any method, be sure it is right for you. It is not wise to depend on any method based upon mnemonics(记忆术). The first words seem very easy to learn, so you buy the course, but then you discover quickly, though too late, that a dozen words later, it is all the more difficult to learn a new word.
