在SAT备考中，语法部分常被学生视为“相对简单”，但实际上其中隐藏的细微陷阱往往最容易失分。澜大教育在多年的教学过程中发现：许多同学虽然对动词形式等基础知识十分熟悉，却常常忽略了句子结构的核心——“主语”的正确形式与逻辑使用。为帮助大家在真实考试中更精准地识别考点、避免常见错误，我们特别整理了SAT官方历年真题，通过典型例题带你吃透“句子完整性之主语”这一高频考点。

一、SAT考试真题攻略

【句子完整性之“主语”常见错误】

在英文中，1个正确的句子必须包含主语和谓语动词。有关”谓语动词VS非谓语动词“的知识点，我相信备考SAT的学生大多已足够熟悉，但针对“主语”设置陷阱的考点，很多学生却不是很清楚，今天我们就来分享几道相关真题：

🌟5种主语形式：

1. 名词

2. 代词

3. 动名词 (短语)

4. 不定式 (短语)

5. 主语从句

二、SAT考试历年真题和答案解析

1.例题1:

【滥用介词短语作主语】

Released in 1987, the Acorn ARM2 microchip contained a single CPU, or core, to execute commands. As processing speeds of single-core chips increased over time, so too did the heat the chips generated. _____ a "power wall" in which more heat was produced than could be efficiently dissipated led developers to invent the dual-core chip in the early 2000s.

Which choice completes the text so that it conforms to the conventions of Standard English?

(A) Hitting

(B) When they hit

(D) Upon hitting

答案：A

解析：该句谓语动词是led, in which more heat was produced than could be efficiently dissipated为从句，修饰前方“power wall”，因此 _____ a "power wall” 需作主语成分，故选A(即动名词短语作主语)。D项错误的主要原因是upon为介词，这样的话, upon hitting a “power wall”则变成了“介词短语”，而介词短语是无法作主语成分的，因此错误。

2.例题2:

【名词和人称代词不可以同时作主语】

Located on the southwest coast of Finland, the city of Turku was a member of a powerful mercantile alliance that dominated northern European trade between the 13th and 17th ______ a loose confederation of cities from eleven modern-day countries, it has been described as a precursor to today’s European Union.

Which choice completes the text so that it conforms to the conventions of Standard English?

A) centuries—the Hanseatic League;

B) centuries: the Hanseatic League,

C) centuries, the Hanseatic League,

D) centuries; the Hanseatic League,

答案：A

解析：划线前是完整句1(主语the city，谓语动词was), 划线后也是完整句2(主语it，谓语动词has been), 因此划线部分需要填入能断句的标点，首先排除C，保留A/B/D项;而B/D错误的主要原因是使用冒号/分号断句后，“the Hanseatic League”会属于完整句2，去掉双逗号间的“a loose confederation of cities from eleven modern-day countries”插入信息后，句2会有名词短语“the Hanseatic League” 和代词“it”同时作主语，错误。故选A。
