Learning Vocabulary-(学习词汇)
A：I don't understand why we have to memorize conversations.We need more vocabulary, not pronunciation.
我弄不懂为什么我们一定要记住会话。我们需要的是词汇，而不是发音。
B：Don't you think memorizing conversations is a part of learning vocabulary?Every time we memorize a conversation, we're memorizing a whole series of contexts.Each context tells us one way a word can be used.I know from my own language that I can't always use words by simply looking them up in a dictionary and then putting them into sentences. Some words have many meanings. We have to know which meanings go where.
你不认为记住会话是学习词汇的一个组成部分吗？每当我们记住一句会话，我们就记住了全部的上下文。而这上下文可以供我们了解一个单词的一种用法。我从自己的语言中意识到，光靠查词典然后把这些词汇拼成句子，并不意味着会正确使用这些词。有些意识有很多解释。我们必须弄清楚在哪种情况下适用哪一种解释。
