☆ 标点线索

　　Example: OG　Practice Set 3， question 4

　　Passage 3: Exhibitors， however， wanted to maximize their profits， which they could do more readily by projecting a handful of films to hundreds of customers at a time (rather than one at a time) and by charging 25 to 50 cents admission…

　　The word readily in the passage is closest in meaning to

　　○ frequently

　　○ easily

　　○ intelligently

　　○ obviously

　　解析：readily 在的文章句子中出现表示附加或补充信息的圆括号()，根据圆括号中的内容，我们可以得出readily在此句中的意思为easily。

　　☆ 构词法

　　根据构词法，单词的结构有三部分：前缀(prefixes)，词干(stems)和后缀(suffixes)。词干是单词的构成基础，前缀和后缀则分别加在词干的前面和后面，从而改变单词的词性和含义。而前缀、后缀和词干都有其固定含义，因此根据构词法，我们就可以利用其固定含义来判断生词的意思。

　　Example: OG NINETEENTH-CENTURY POLITICS IN THE UNITED STATES

　　Passage 1: …During his administration he immeasurably enlarged the power of the presidency…

　　The word immeasurably in the passage is closest in meaning to

　　○ frequently

　　○ greatly

　　○ rapidly

　　○ reportedly

　　解析：immeasurably一词的词根为measure(测量、度量)，词缀分别为im-(不)，-able(能…的)，-ly(由形容词变为副词)。因此我们可以判断immeasurably一词在此句中的意思为greatly?

　　○ uncertain

　　解析：despondent 所在的文章句子中出现疑问句，疑问句中的连词or 表示选择，因此我们可以得出despondent在此句中的意思为unhappy?
