Example: OG  Practice Set 3, question 11

Passage 6: With the advent of projection, the viewer’s relationship with the image was no longer private, as it had been with earlier peepshow devices such as the Kinetoscope and the Mutoscope, which was a similar machine that reproduced motion by means of successive images on individual photographic cards instead of strips of celluloid. It suddenly became public –an experience that the viewer shared with dozens, score, and even hundreds of others. At the same time, the image that the spectator looked atexpanded from the minuscule peepshow dimensions of 1 or 2 inches (in height) to the life-size proportions of 6 or 9 feet.

The word expanded in the passage is closest in meaning to

○ was enlarged

○ was improved

○ was varied

○ was rejected

解析：expanded所在的文章句子中出现从“1 or 2 inches”到“6 or 9 feet”, 因此我们可以轻而易举得出expanded在文章中上下文意思为 was enlarged。

☆ 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。
