转换：The building which will be built by them next month will be our new teaching building.

非谓语动词：The building to be built by them next month will be our new teaching building.

二、当定语从句一般现在时态、一般过去时态时或完成时态时，需要根据非谓语动词与其逻辑主语之间的关系选择适当形式的非谓语动词形式，通常主动关系用doing,having done, to do; 被动关系用done, being done,having been done, to be done。

E.g.1：定语从句：The soldier who devoted his whole life to his country deserves the great glory.

非谓语动词：The soldier devoting his whole life to his country deserves the great glory.(devote与其逻辑主语soldier之间是主动关系)

那个将一生奉献给祖国的军人值得这一伟大的荣耀。

E.g.2：定语从句：He lives in a house that faces the south.

非谓语动词：He lives in a house facing the south.(face与其逻辑主语house之间是主动关系)

　　 他住在一个朝南的房子里（他住的房子面朝南）。

E.g.3：定语从句：The film that she has seen for three times is called The Avengers 3.

　　　　　转换：The film that has been seen by her for three times is called The Avengers 3.

非谓语动词：The film having been seen by her for three times is called The Avengers 3.(see与其逻辑主语film之间是被动关系)

　　 那部她看了3遍的电影叫复仇者联盟3。

三、定语从句中如含有情态动词或先行词前有序数词、last、only等修饰时，通常将定语从句变为不定式短语作后置定语。

E.g.1：定语从句：You need someone who can look after you.

　　　非谓语动词：You need someone to look after you.

　　　　　　　　你需要个人来照顾你。

E.g.2：定语从句：She is the only one that figured out the difficult maths problem.

　　　非谓语动词：She is the only one to have figured out the difficult maths problem.（由于figure out已发生，所以此处用完成时态的不定式形式）

　　　　　　　　她是唯一一个算出这道数学难题一个人。

E.g.3：定语从句：He is always the first one that arrives at school.

　　　非谓语动词：He is the first one to arrive at school.

　　　　　　　　他总是第一个到学校的人。

四、若定语从句中含有"拥有"意义的动词has, have, had 时，用介词with, without.

E.g.1：定语从句：The old man who had a pipe in his mouth sat under the tree.

非谓语动词：The old man with a pipe in his mouth sat under the tree.

嘴里叼着一个烟斗的老人坐在树下。
