For such sentences, this is the format to use:
[Pronoun] は [noun]を[verb]
For eg:
- Watashi wa gohan o tabemasu. = 私はご飯を食べます。= I eat rice.
(gohan = rice; tabemasu = eat)
- Kanojo wa kaban o kaimasu. = 彼女はかばんを買います。
(kaban = bag; kaimasu = buy)
For simpler action sentences like he runs, they walk:
[Pronoun] は[verb]
Thus,
- Kare wa hashirimasu. = 彼は走ります。= He runs.
(hashirimasu = run)
- Karera wa arukimasu. = 彼らは歩きます。They walk.
(arukimasu = walk)
* In Japanese language, there are no singular and plural forms. Thus the same verb: hashirimasu and arukimasu, can be used for a single person or many people.
