Hello there! As an expert in the field of English language usage, I'm here to provide you with a comprehensive answer to your question about punctuation and spacing in English writing.
When it comes to the use of brackets in English, there are a few key rules to keep in mind. Brackets are punctuation marks that are used to insert additional information or commentary within a sentence. They can also be used to indicate the omission of words from a quote. There are different types of brackets, including parentheses (圆括号), square brackets (方括号), and curly brackets (花括号), each serving a slightly different purpose.
Let's start by discussing the spacing rules for parentheses, which are the most commonly used type of bracket in English writing. The general rule for spacing around parentheses is as follows:

1. **Put a space before the opening parenthesis**: This is done to separate the parenthesis from the preceding word or phrase, making it clear that the information within the parenthesis is additional and not part of the main sentence structure. For example, in the sentence "She has a dog (a black Labrador)," the space before the opening parenthesis helps to visually distinguish the additional information about the dog.

2. **Either a space or a punctuation mark after the closing parenthesis**: The choice between a space and a punctuation mark after the closing parenthesis depends on the context. If the information within the parenthesis is a complete sentence or a standalone thought, a punctuation mark (such as a period, comma, or exclamation point) should follow the closing parenthesis. However, if the information within the parenthesis is not a complete sentence and is closely tied to the preceding text, a space is used instead. For example, "He was late (he had an accident)" uses a space because the information is closely connected to the preceding clause.

Now, let's address the specific question of whether to put a space before a bracket. In English, the term "bracket" can refer to different types of punctuation marks, but the general rule for spacing applies to parentheses as described above. For square brackets and curly brackets, the rules can vary slightly depending on the context and the style guide being followed. However, the same principles of clarity and visual distinction apply.

It's important to note that different style guides (such as APA, MLA, Chicago, etc.) may have specific rules regarding the use of brackets and spacing. For instance, in academic writing, it's crucial to adhere to the guidelines set by the relevant style guide to ensure consistency and professionalism.

In summary, when using parentheses in English writing, it's important to:

- **Use a space before the opening parenthesis** to clearly indicate the start of additional information.
- **Use either a space or a punctuation mark after the closing parenthesis**, depending on whether the information within the parenthesis is a complete sentence or not.

Remember, the goal of using punctuation and spacing correctly is to enhance readability and ensure that your writing is clear and easy to understand. By following these rules, you can effectively use parentheses and other brackets to add depth and clarity to your writing.
