ACT英语10大易错语法

　　小编整理ACT英语中10大易错语法，希望能对各位考生有所帮助。

　　以下10个错误涵盖了几乎所有ACT的标准语法规定问题，所附示例仅用于说明错误，不代表实际考试问题和难度;每一点的第一句斜体句是有错误的，第二句才是正确的。

　　1. Punctuation 标点符号

　　Frederick Law Olmsted the famous landscape architect, was also a conservationist.

　　Frederick Law Olmsted, the famous landscape architect, was also a conservationist.

　　解析：Frederick Law Olmsted和the famous landscape architect指代同一事物，为同位语，两个名词之间需要用逗号隔开。同位语是常见的插入成分，理解意思时可以连同逗号一同删除。

　　2. Pronouns 代词问题

　　Each of the trees had dropped their leaves.

　　Each of the trees had dropped its leaves.

　　解析：Each of the trees强调每一棵树，是单数概念而their是复数概念。所以在指代时应用its。

　　3. Verb Tense and Agreement 动词时态一致

　　I planted vegetables last year, but a late frost kills my tomatoes.

　　I planted vegetables last year, but a late frost killed my tomatoes.

　　解析：本句结构为but引导的并列句，前句给出planted为过去式，后句时态应保持一致，用过去式killed。

　　4. Parallel Structure 平行结构

　　The subjects Shana likes best are biology, physics, and studying French.

　　The subjects Shana likes best are biology, physics, and French.

　　解析：句中由and引导并列, 前两个被并列成分为biology/ physics 所以为了格式应保持一致，应为French。

　　5. Sentence Fragments 句子分段

　　While Charlie was at the beach to enjoy the sunshine and the ocean breeze.

　　While Charlie was at the beach, he enjoyed the sunshine and the ocean breeze.

　　解析：由while引导的状语从句放在句首时，应用逗号和主句分隔开，标志从句结束。

　　6. Comma Splices 逗号拼接

　　I moved to Washington when I was seven, my brother followed a year later.

　　I moved to Washington when I was seven, and my brother followed a year later.

　　解析：英语句法上规定，每个句子有且仅可以有一个动词，而无论句子中有多少个逗号，本质还是一个句子。因此在第一句中出现了两个动词，是错误的。应改为and引导的并列句。

　　7. Conjunctions 连接词

　　Thomas had been walking for miles, so he finally spotted his campsite in the distance.

　　Thomas had been walking for miles when he finally spotted his campsite in the distance.

　　解析：he finally spotted his campsite in the distance句意上应为Thomas had been walking for miles这件事发生的时间，连接词改为when。如果两句之间用so连接，前句应为后句的结果。

　　8. Faulty Modification 错误改正

　　Leaping from the window onto the roof, Grandma was delighted by the cat’s agility.

　　Leaping from the window onto the roof, the cat delighted Grandma with its agility.

　　解析：在Leaping from the window onto the roof这个部分，Leaping这个动词发出者被省略，但是只有在发出者和主句动词发出者一致时才能省略。Leaping这个动词发出者为cat而不是grandma，所以做以上更正。

　　9. Idioms 习惯用语

　　Choosing where to apply about college is a difficult process for high school students.

　　Choosing where to apply to college is a difficult process for high school students.

　　解析：apply作为不及物动词搭配to使用，意思为申请…。

　　10. Frequently Confused Words 高频率混淆单词

　　I completed all of the summer reading accept the Jane Austen novel.

　　I completed all of the summer reading except the Jane Austen novel.

　　解析：本题考查形近词，音近词辨析。accept，动词，意思为接受。而except，介词，意思为除了…。
