　　①东京也无非是这样。②上野的樱花烂熳的时节，望去确也像绯红的轻云，但花下也缺不了成群结队的“清国留学生”的速成班，头顶上盘着大辫子，顶得学生制帽的顶上高高耸起，形成一座富士山。③也有解散辫子，盘得平的，除下帽来，油光可鉴，宛如小姑娘的发髻一般，还要将脖子扭几扭。④实在标致极了。

　　⑤中国留学生会馆的门房里有几本书买，有时还值得去一转；倘在上午，里面的几间洋房里倒也还可以坐坐的。⑥但到傍晚，有一间的地板便常不免要咚咚咚地响得震天，兼以满房烟尘斗乱，问问精通时事的人，答道，“那是在学跳舞。”

In order to know a foreign language thoroughly(完全地), four things are necessary. First, we must understand the language when we hear it spoken. Secondly, we must be able to speak it ourselves, correctly with confidence(自信) and without hesitation(犹豫). Thirdly, we must be able to write it. We must be able to make sentences that are correct in grammar.

There is no short way to succeed in language learning. A good memory(记忆) is a great help, but it is not enough only to memorize the rules from a grammar book. It is no much use learning by heart long lists(一览表) of words and their meanings, studying the dictionary and so on. We must learn by using the language. If we are pleased with a few rules we have memorized, we are not really learning the language. We must “Learn through use”. Practice is important. We must practise speaking and writing the language whenever(无论何时) we can.
