There should be spaces after numbers and punctuation marks in English writing format, and there are also some rules: the correct use of capital letters in writing is a problem that can not be ignored.

Capital letters are not only used at the beginning of sentences, proper nouns, etc. You should also pay attention to the following situations: the first letter of direct speech in a sentence should be capitalized, regardless of whether the description of "so-and-so" is at the beginning or the end of the sentence.

For example, she said, "This kind of thing is unreasonable." But when direct speech is a continuation of a sentence, capital letters are not used.

For example, "it's unreasonable to expect such a thing," she said. Generally, the initials of nouns indicating school subjects are lowercase, but the initials of language subjects such as Chinese and English are capitalized.
