为什么句型变化在SPM中很重要
SPM英文评分标准明确奖励”句型多样化”。如果整篇作文只用简单句，就算语法完美，也只能到Band 3。考官想看到你能驾驭不同的句型结构。
好消息：只需要学4种。
第一种：简单句（Simple Sentence）
简单句有一个独立分句——一个主语和一个谓语。
例子：
- She studies every day.
- The students completed the project.
- Rain fell heavily last night.
简单句可以很长吗？ 可以。简单句可以有复合主语、复合谓语或附加短语：
- The teacher and her students visited the museum. （复合主语，仍是一个分句）
- She read the passage and answered the questions. （复合谓语，仍是一个分句）
什么时候在SPM作文中用：
- 需要力量感的开头句
- 长句之后用短句制造节奏
- 陈述关键事实或结论
第二种：并列句（Compound Sentence）
并列句用并列连词（FANBOYS：For, And, Nor, But, Or, Yet, So）或分号连接两个独立分句。
例子：
- She studied hard, and she passed the exam.
- The weather was terrible, but we continued the trip.
- He didn’t bring an umbrella, so he got wet.
标点规则： 连接两个完整句子时，在连词前加逗号。
SPM常见错误： 用”and”连接所有内容：
- 差： “I woke up early and I ate breakfast and I went to school and I was late.”
- 好： “I woke up early and ate breakfast, but I was still late for school.”
第三种：复合句（Complex Sentence）
复合句有一个独立分句和至少一个从属分句，用从属连词连接。
常见从属连词
| 用途 | 连词 |
|---|---|
| 时间 | when, while, after, before, until, since |
| 原因 | because, since, as |
| 条件 | if, unless, provided that |
| 对比 | although, even though, whereas |
| 目的 | so that, in order that |
例子：
- Although she was tired, she continued studying.
- He failed because he didn’t prepare.
- When the bell rang, the students rushed out.
- She will pass if she practises every day.
标点规则： 从属分句在前时，后面加逗号。独立分句在前时，通常不需要逗号。
为什么复合句得分高： 它表明你能表达思想之间的关系——因果、条件、对比。这正是Band 4-5的要求。
第四种：并列复合句（Compound-Complex Sentence）
并列复合句有至少两个独立分句和至少一个从属分句。
例子：
- Although the exam was difficult, she answered every question, and she finished on time.
- He wanted to join the team, but his parents disagreed because they thought it would affect his studies.
什么时候用： 适合在主体段落中展开论点。不要过度使用——每篇作文一两个就够了。
SPM作文的句型分配
Band 5作文通常用这样的比例：
| 句型 | 大约比例 |
|---|---|
| 简单句 | 20-30% |
| 并列句 | 25-30% |
| 复合句 | 30-35% |
| 并列复合句 | 5-10% |
核心原则： 变换句型。不要连续用五个简单句，也不要每句都是复合句。
如何升级你的句子
简单句 → 并列句
- 简单句： She studied. She passed.
- 并列句： She studied hard, and she passed the exam.
简单句 → 复合句
- 简单句： She passed. She studied.
- 复合句： She passed because she studied every day.
并列句 → 并列复合句
- 并列句： She studied hard, and she passed.
- 并列复合句： Although the exam was tough, she studied hard, and she passed.
SPM常见句型错误
错误一：连写句（Run-on）
错： “She studied hard she passed the exam.” 对： “She studied hard, and she passed the exam.”
错误二：逗号拼接（Comma Splice）
错： “She studied hard, she passed the exam.” 对： “She studied hard, so she passed the exam.”
错误三：句子片段（Fragment）
错： “Because she studied hard.”（不完整的思想） 对： “She passed because she studied hard.”
练习
判断句型：
- The students arrived early. → 简单句
- She wanted to speak, but she was nervous. → 并列句
- Because it rained, the event was cancelled. → 复合句
- Although he was tired, he finished the essay, and he submitted it on time. → 并列复合句
把下面的简单句改成复合句：
- She passed the exam. She studied every night. → She passed the exam because she studied every night.
- The students were quiet. The teacher entered. → The students were quiet when the teacher entered.
