这期的文章将介绍简化关系子句的几种方法：
方法一：将关系子句改为形容词词组
原句：Jane, who was late again today, sat next to me during lunch.
简化后：Jane, late again today, sat next to me during lunch.
原句：The wife, who was angry with her husband, did not return home last night.
简化后：The wife, angry with her husband, did not return home last night.
以上两个例句中，省略了关系子句的关系代名词 + “be” 动词（who was），简化成形容词词组。省略后的形容词词组与原句的关系子句拥有修饰前面名词的功能。
方法二：将关系子句改为动词分词词组
原句：The dog which is sitting at the door is waiting for its owner.
简化后：The dog sitting at the door is waiting for its owner.
同样地，省略掉原句中的关系代名词 + “be” 动词（which is），用动词分词词组来修饰主语。
以下两个例句则使用另一种简化方式。
原句：The man who lives next door teaches in a public school.
简化后：The man living next door teaches in a public school.
原句：Students who hand in the report late will lose five marks.
简化后：Students handing in the report late will lose five marks.
句中的关系代名词（who）与后面的动作是主动关系，把关系代名词 “who” 删除后，动词改为现在分词，简化成分词词组，修饰前面的主语。
原句：We all read the e-mail that was sent by the manager earlier today.
简化后：We all read the e-mail sent by the manager earlier today.
原句：Discrimination that is based on race, gender, age, or disability is not allowed.
简化后：Discrimination based on race, gender, age, or disability is not allowed.
以上两个例句中的关系子句使用被动语态，直接将关系代名词 + “be” 动词（that was/that is）省略后就形成过去分词的分词词组。
方法三：将关系子句改为介词词组
原句：The woman who is in the meeting room is our new team member.
简化后：The woman in the meeting room is our new team member.
此句同样出现关系代名词 + “be” 动词（who is），直接省略掉后，剩下 “in the meeting room” 就是介词词组。
原句：The two-story house that had a beautiful front yard was sold $300,000.
简化后：The two-story house with a beautiful front yard was sold $300,000.
关系子句中即使没有关系代名词 + “be” 动词的部分还是能简化为介词词组。以上句为例，关系子句中的动词 “had” 可以使用介词 “with” 来替换，将关系代名词删除后就能形成介词词组。
另外有时候，关系子句有不止一种简化方式；以下两个例句给出了分词词组以及介词词组的改写形式。
原句：The student who is wearing a blue jacket is a member of the science club.
简化后：
- The student wearing a blue jacket is a member of the science club.
- The student in a blue jacket is a member of the science club.
原句：The lady who is standing on the stage is the newly elected mayor.
简化后：
- The lady standing on the stage is the newly elected mayor.
- The lady on the stage is the newly elected mayor.
