Day 99: Use subject pronouns, not object pronouns, as subjects.

The subject pronouns are I, you, he, she, it, we, they, and who. The object pronouns are me, you, him, her, it, us, them, and whom. When you need a pronoun as the subject of a verb, use a subject pronoun.

Very few people make errors when only using one pronoun. However, when the subject is compound, errors are more common. For example, I occasionally hear or read something like this:

广告：个人专属 VPN，独立 IP，无限流量，多机房切换，还可以屏蔽广告和恶意软件，每月最低仅 5 美元

“Me and her went to the movies.”

In this example, the main verb is “went,” and the subject is “me and her.” These are not subject pronouns. Instead, this should be written

“She and I went to the movies.”

Sometimes this is even more complicated. The pronouns may be the subject of a verb that is not the main verb. Consider this sentence.

“The postman knocked when him and I were at home.”

The pronouns “him and I” are serving as the subject to “were.” “Him” is not a subject pronoun, so the sentence should be written

“The postman knocked when he and I were at home.”

You can use this trick. Write the sentence with one pronoun at a time and listen to how the sentence sounds: “When him was at home” vs. “When he was at home.” Which one sounds correct? A native English speaker will choose the correct option nearly every time.
