小站君要潜入SAT考试大军，传播正能量，传播SAT语法知识，真材实料，今天给大家讲解SAT语法中的句子简洁，童鞋们看过来。
简洁原则一共有六个考点，通常是简洁原则融合在其他知识点中反复考查。请看下面的具体讲解。
考点一. 结构简洁原则：词比短语简洁，短语比句子简洁。
考点二. 词语简洁原则： 动词比形容词简洁，形容词比副词简洁，副词比名词简洁，名词比动名词简洁。
考点三.主动语态比被动语态简洁
比较下面三种表达方式，看谁更为简洁：
to reduce …
with his purpose being to reduce …
with his purpose that is to reduce …
请看下列真题：
The programmers always talked of having too much to do, but in truth they had a lesser
amount of work to do than their colleagues.
(A) they had a lesser amount of work to do
(B) their work was the least among
(C) they were having less work to do than

(D) the amount of work they had to do was the least of
(E) they had less work to do than
E选项才是正确的，原句中的lesser错误，有less的选项才对，E比C明显更为简洁，时态也更加准确。
考点四. 包含being的选项易错(除非being用作时态助词)
考点五. 表意重复的选项必错
例如：may VS possible, enough VS sufficient
考点六. 表原因时使用because或because of比其他句型更简洁
请看真题：
The villagers found the visitors equally as fascinating as their customs were mystifying.
(A) equally as fascinating as their customs were
(B) equally fascinating and their customs were
(C) as fascinating as their customs
(D) as fascinating as their customs were
(E) as fascinating and their customs were
D选项才是正确的，原句中的equally和as...as明显违背了考点五，所以A错误。且as...as是固定搭配，C违背了比较结构的可比性原则，还不了解可比性原则的请戳：开学大礼包-SAT语法系列讲座-比较结构，原句中的mystifying也没有对应搭配。
以上就是简洁原则的讲解，同学们学会考点后去完成相应的习题，对简洁原则进行训练。
