Direct sentence and transitive sentence are two concepts in grammar. A direct sentence is a sentence stating facts or opinions. Usually, the subject comes before the verb, and punctuation marks are needed at the end of the sentence. For example, "I like ice cream." This is a simple direct sentence, which shows the author's preference.

In contrast, transitive sentences refer to other people's words or thoughts and present them as their own statements. Transitive sentences usually use quotation marks and appropriate quotation forms (such as "what he said" or "what she thought") to show that opinions come from others, not themselves. For example, "he said this problem is not easy to solve." This is a transitive sentence because it quotes other people's words.

Generally speaking, direct sentences are more about presenting the author's own thoughts and opinions, while transitive sentences are more about emphasizing the words or thoughts of others. In addition, the direct sentence is more objective, and the transitive sentence may be more subjective, because as a reporter, there may be selection and filtering when quoting.

In writing and oral communication, we need to choose the appropriate sentence structure according to the situation and purpose. We usually use direct sentences to express our thoughts and opinions, but we need to use transitive sentences when quoting others' words. At the same time, understanding and using these two sentence patterns will also help us to accurately understand and explain other people's views.
