为 Introducing a Beneficiary in Chinese
为 + 对象
The preposition 为 introduces the person or group whose interests an action serves. The complete 为 phrase normally appears before the predicate, as in cooking for a family or buying something for students. This beneficiary use is distinct from formal 因为-like cause marking and from 为 pronounced wéi as a verb.

The preposition 为 introduces the person or group whose interests an action serves. The complete 为 phrase normally appears before the predicate, as in cooking for a family or buying something for students. This beneficiary use is distinct from formal 因为-like cause marking and from 为 pronounced wéi as a verb. Keep the model Subject + 为 + Beneficiary + Predicate visible while you compare each sentence.
妈妈每天为我们做饭。
Mom cooks for us every day.
Choose the right context
Name the beneficiary of an action. Place the beneficiary phrase before the predicate. Describe service, preparation, or action done for someone.
孙老师为我们买了一束花。
Teacher Sun bought a bouquet for us.
Respect the boundary
Do not split 为 from its beneficiary with the verb. Do not place the beneficiary after a broken predicate. Do not read beneficiary 为 as wéi or treat it as a copular verb.
妈妈每天为做饭我们。
(Mom for cooks us every day.)
Repair the pattern
The verb splits 为 from its beneficiary: 为 must directly introduce its beneficiary before the action predicate. The beneficiary is stranded after the object: The complete 为我们 phrase must precede the verb and its object.
妈妈每天为我们做饭。
Use the repaired structure without changing the intended meaning.
