The average person learns most of the 30 000～40 000 words whose meanings he or she recognizes by hearing them or getting familiar with them in the context or simply absorbing them without conscious effort. The best way to build a good vocabulary, therefore, is to read a great deal and to participate in a lot of good talks. There are relatively few words that we learn permanently by purposefully referring to dictionaries or keeping word lists. However, even those extra few are of value, and no one will make a mistake by working on developing a larger vocabulary. Here are some suggestions of how to do it.

Read plenty of good books. When you come across a new word, or a new meaning of an old word, stop and see if you can understand it from its context. If you can't, and if you can manage without interrupting the thought of the book too much, look it up in a dictionary or ask somebody and then repeat its meaning to yourself a couple of times. If you are really conscientious(认真的), write the word and its meaning in a personal vocabulary list － preferably using it in a sentence, or you can keep a special vocabulary notebook. Go over the list from time to time. Further, try to use a new word in writing or conversation a few times over the next several days.

Listen to good talks and be alert to new words you hear or to new meanings of words you already know. Then treat them just as you treat the new words you read.

Learn and be alert to the parts of words: prefixes, suffixes and roots. Knowing them enables you to make intelligent guesses about the meanings of words.

If you are studying a foreign language, be alert to words in that language which relate to words in English. English has inherited(继承) or borrowed much of its vocabulary of 500 000～600 000 words from Latin, Greek, French, Spanish and German.

Freshmen, eager to get home for the Chinese New Year, queue up at the railway station for hours．Days later, they squeeze into a crowded train and dream of the home-cooked meals and love they'll enjoy once they arrive home．This, they say, makes all the trouble of getting home worthwhile.
However, many freshmen come to find that home is not exactly how they remembered it．Living away from their parents has exposed them to a new life of freedom – one that within hours of arriving some begin to miss．Household chores（家务活）and complaining parents are just a few of the things that can ruin students' winter fantasies．“My parents still treat me like I was in senior high,” Song Ying, a 19-year-old freshman at Shandong University, complained．“I get an earful from them every day.”
During her first term away from her Hubei home, Song missed everything – from her parents cooking to the city bus．She cried and ached to sleep in her own bed．So, upon finishing her exams, she fled home, thinking everything would be just as it used to be．But she was wrong．Now, she spends entire days at a friend's home to “avoid all the restrictions”．She logs online to update friends' profile on SNS, skips meals and sleeps in – just like she did on campus.
Things have been even tenser at home for Luo Ruiqi, a 19-year-old freshman at Beijing Jiaotong University．Instead of moving to a friend's house, though, he has decided to challenge his parents' rules for his right to be an adult at home．When they complained about the amount of time he spent in the toilet, Luo said he decided “enough is enough” and lost his temper．He feels guilty about his attitude, but he still argues that he is grown up enough to live by his own rules．“I just want to live my own way of living, wherever I am,” said Luo．
Recent graduates like Wang Kai know what Song and Luo are going through．But Wang, who graduated in 2008 and now works in Beijing, says students should value the time spent with their family and “just try to be nicer.” Wang says he acted the same way when he first returned home from college, but now, living 1,500 km away from his hometown in Hunan, he regrets his behavior．He realizes that his parents meant well．And, looking back, he says that “the way of living that we got used to on campus is not that healthy anyway”.
Parents, meanwhile, are more understanding than you might think．“Living on their own in a strange place can be hard –we've been there before,” said Luo's father．“We want to make sure that they are healthy and happy．Sometimes maybe we just worry too much.” As for the tension that's arisen between father and son, Luo senior laughed and said, “It's not a problem at all – he's my son; we work things out, always.”
