2016年改革之后，对于新SAT考试的标点符号考点，已经成为必考的一个项目，因此同学们关于这个SAT考试内容是一定要把握住的，不要失分。今天为大家带来的就是sat作文修改符号之冒号!
一、冒号
起到解释说明或举例的作用，后面可以添加一个句子或短语，往往会出现“前总后分”的效果
Soul food is a varied cuisine： it includes spicy gumbos, black-eyed peas, and collard greens.
At least three soul food dishes are familiar to most Americans： fried chicken, barbecued spareribs, and sweet potato pie.
OG Test 1 第16题
But Jason 15 Box, an associate professor of geology at Ohio State, believes that another factor added to the early 16 thaw; the “dark snow” problem.
A) NO CHANGE
B) thaw: and it was
C) thaw:
D) thaw: being
答案：C
解析：A选项里有分号，且分号后面必须添加完整的句子，而the “dark snow” problem只是一个名词短语，不是句子，因此，A选项错误。B选项中was体现出了过去时，而原文中believes是一般现在时，时态冲突，且and后面如果添加完整的句子，and前应该有逗号，而不是冒号，所以B排除。而D选项中being不能放于冒号后面使用(being在SAT考试中只能放于及物动词后/介词后使用，或组成进行时的被动语态使用，其他情况下使用being都是错误的)，所以排除D选项。而C选项中冒号后面添加了一个名词短语，是可以的，而“dark snow” problem是对前面factor这个名词的解释说明，符合冒号的功能，是正确的。
二、分号
在SAT考试考到标点符号的时候，我们应该要明确一些时间，比如考虑这个SAT考试内容汇总出现标点符号是否影响句子主干，另外就是该标点符号的语义作用是不是符合。同学们在新SAT备考的时候，要多多的考虑这样的问题。再来看分号。
分号的第一个常见用法是：
It’s used between two main clauses that balance each other and are too closely linked to be made into separate sentences (oxford dictionary)
即隔开两个相关且独立的分句，所以分号前后一般是完整的句子。
这个规则可以帮助我们很快的去确定选项正误。
Eg: An art director searched North Africa; I went to the Canary Islands.
例题：
the name kingman was elected for its two parts, “king” and “man”; Cantonese for “scenery” and “composition.”(og:dong kingman)
A no change
B parts: “king” and “man,”
C parts “king” and “man”;
D parts ;“king” and “man”
首先扫读选项，确定考点：标点符号，在这我们会发现至少有三个选项都是使用分号：分别是acd，但是根据句子结构判断，都不符合前后是完整句子，直接排除。选择b ：用冒号来表示解释说明。
分号还有第二个用法：
used to separate the parts of a complicated sentence or items in a detailed list, showing a pause that is longer than a comma but shorter than a full stop/period
(该用法在新sat中暂未考察过，此处只做补充。)
eg: The study showed the following: 76% of surveyed firms monitor employee Web-surfing activities, with 65% blocking access to unauthorized Internet locations; 57% monitor employee telephone behavior, including the inappropriate use of voicemail.
The designer envisions the game’s fundamental 35elements: the settings, characters, and plots that make each game unique, and is thus a primary creative force behind a video game. (og4-35)
A) NO CHANGE
B) elements: the settings, characters, and plots that make each game unique—
C) elements—the settings, characters, and plots that make each game unique—
D) elements; the settings, characters, and plots that make each game unique;
同理，第一，扫读选项，确定考点。第二，回到原句理解语义the settings, characters, and plots that make each game unique 应该是fundamental elements的列举，因此大家应该能比较快的排除bd选项：b选项破折号使用错误。D选项分号前后应该是完整句子。大部分同学会在ac之间纠结。事实上，a 选项冒号前面虽然是完整的句子，但是and is thus a primary creative force behind a video game并非是冒号所涵盖的内容，是句子的主干成分(整个句子完整的逻辑语义是：The designer envisions the game’s fundamental elements， and is thus a primary creative force behind a video game.)不能直接放在冒号后面。所以a 选项错误。答案选c.
