同样的要点，全用简单句平铺是二档文，换成从句、分词、倒装就是一档文——句式升级是作文提分性价比最高的动作，背四五个升级句式加一组衔接词就能落地。
句式升级对照表
| 平淡句 | 升级句 | 升级手法 |
|---|---|---|
| The girl is my sister. She is wearing a red coat. | The girl who is wearing a red coat is my sister. | 合并为定语从句 |
| He heard the news. He jumped with joy. | Hearing the news, he jumped with joy. | 改为分词作状语 |
| I knew the truth only then. | Only then did I know the truth. | 改为倒装句 |
| It was a fine day. We went out. | It being a fine day, we went out. | 改为独立主格 |
| The problem is very hard. We can't solve it. | The problem is too hard for us to solve. | 改为 too ... to 结构 |
衔接词分类清单
- 递进：besides、what's more、in addition、moreover
- 转折：however、but、on the contrary、in spite of
- 因果：therefore、as a result、thanks to、due to
- 列举：first of all、secondly、finally、for one thing ... for another
- 举例：for example、such as、take ... for example
- 总结：in a word、all in all、in conclusion、to sum up
使用原则：一段一到两个衔接词足够；同一篇里不要重复用同一个；衔接词位置通常在句首加逗号，或句中用分号隔开。
易错点：衔接词堆砌与误用逻辑
衔接词是「润滑剂」不是「得分词」：一段里塞三四个 On the one hand、What's more、In addition，阅卷老师看到的是套路感，反而在语言项扣分。更隐蔽的失分是逻辑误用——前后句明明是因果却用了 however，转折关系套了 besides。判断方法写完通读：盖住衔接词只看内容，确认两句间的真实逻辑关系，再检查衔接词是否匹配。升级句式同理：一篇作文倒装、强调、独立主格各用一次是亮点，全堆在一起就是表演，语言分反而下降。
