2. A period is used to divide complete English sentences, and commas are used between internal components. For example, "They like me. This makes me very happy. " Are two complete sentences, and each sentence must be followed by a period.
And if it is "they like me, which makes me very happy." The main clause comes first and the clause comes last to form a complete sentence with a comma in the middle and a period after it.
Don't put spaces between punctuation marks and previous words. Spaces are used to separate words, and punctuation marks should be after the last list. Like, "I'm fine." Not "I'm fine."
There must be a space between the punctuation marks of each sentence and the previous sentence. Spaces are used to separate words. If there is no space between the two sentences, then the last word of the previous sentence and the first word of the next sentence are connected.
For example, "I'm here. _It_is_8:00_now。” If it is written as "I am here. It's eight o'clock. " , then "here.it" is not standardized and will only appear in the same word, such as "A.M." and "U.S.A"
The above "here.it" may even be regarded as a link URL by some websites, because ". "It" is a domain name with no spaces in the URL.
5. If English and Chinese coexist, add a half-angle space between English words and Chinese. For example, "I saw a CNN report today." "There is wood in the Chinese character tree in China" and so on.
