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.

解析
A study led by Professor Mark Weiser of Tel Aviv University and the Sheba Medical Center at Tel Hashomer Hospital has determined that young men who smoke are likely to have lower IQs than their non-smoking peers (同龄人). Tracking 18-to 21-year-old men enlisted in the Israeli army in the largest ever study of its kind, he has been able to demonstrate an important connection between the number of cigarettes young males smoke and their IQ.
The average IQ for a non-smoker was about 101, while the smokers’ average was more than seven IQ points lower, at about 94, the study determined. The IQs of young men who smoked more than a pack a day were lower still, at about 90. An IQ score in a healthy population of such young men, with no mental disorders(心理疾病), falls within the range of 84 to 116.
An addiction that doesn’t discriminate(歧视)
“In the health profession, we’ve generally thought that smokers are most likely the kind of people who have grown up in difficult neighborhoods, or who’ve been given less education at good schools,” says Weiser, whose study was reported in a recent version of the journal, Addiction, “But because our study included subjects with various socio-economic backgrounds, we’ve been able to rule out socio-economics as a major factor. The government might want to rethink how it arranges its educational resources on smoking.
Making the results more significant, the study also measured effects in twin brothers. In the case where one twin smoked, the non-smoking twin registered a higher IQ on average.
Although a lower IQ may suggest a greater risk for smoking addiction, the representing data on IQ and smoking found that most of the smokers investigated in the study had IQs within the average range, nevertheless.
In the study, researchers took data from more than 20,000 men before, during and after their time in the military. All men in the study were considered in good health, since pre-screening(筛选的)measures for suitability in the army had already been taken. The researchers found that around 28 percent of their samples smoked one or more cigarettes a day, 3 percent considered themselves ex-smokers, and 68 percent said they never smoked.
“People on the lower end of the average IQ tend to display poorer overall decision-making skills when it comes to their health,” says Weiser. He adds that his finding can help address serious concern among heath counsellors at grade and high schools.
