长难句突破：定语从句 (Relative Clauses)

定语从句是扩充句子容量、增加信息密度的核心手段。它能帮你把两个简单句合并为一个复杂的复合句。

1. 基础合并 (Basic Combination)

• Simple A: Technology is a tool.
• Simple B: This tool improves efficiency.
• Combined: Technology is a tool which/that improves efficiency.

2. 进阶技巧：非限制性定语从句 (Non-defining Clauses)

使用逗号隔开，补充说明额外信息（而非限定）。这对 Task 2 解释概念非常有用。

• Example: The internet, which connects people globally, has revolutionized communication.
• Example: University education, which is often free in Europe, promotes social mobility.

3. 高分技巧：介词 + Which

这是 7 分以上的标志性句型，常用于正式文体。

• in which (where):
  • Instead of: The situation where we live...
  • Better: The situation in which we find ourselves...
• through which (how/by which):
  • Better: This is the mechanism through which the virus spreads.
• with which:
  • Better: The ease with which information can be checked is remarkable.

4. 实战模板

• Those who... (那些...的人)
  • Example: Those who support strict censorship argue that it protects children.
• ..., a situation which... (这种情况...)
  • Example: Housing prices are soaring, a situation which forces many young people to rent.
