How to modify English exclamatory sentences and how to combine sentences into one sentence

1. How to modify English exclamatory sentences: For example, if you want to say "It's a beautiful day today!" the single sentence is: It's a beautiful day. 1. Use what to modify: What a beautiful day! That is what + noun

2. Use How to change: How beautiful the day is! That is, how + adjective

2. Combine the sentences into one sentence: I think you mean how to change the two single sentences into attributive clauses. For example, He speaks to that girl. That girl is a teacher.

Changed to an attributive clause it should be: That girl whom/who he speaks to is a teacher.

The antecedent is girl (person), so who/who should be used as the relative word. Because girl in this sentence is the object, who/who can be used. If it is the subject, only who can be used. If the subject is a thing, then the relative word which/that should be used. And the relative word should immediately follow the antecedent. Generally speaking, there are many things to pay attention to in attributive clauses. If you don’t understand anything, you can ask me. I can leave my QQ to you.
