Apostrophes are not used with personal pronouns, but are used in contractions.
Your, describes ownership. It is a personal pronoun.
You’re, is a contraction and an abbreviation for you are.
“You're" 是 “You are " 的缩写
Therefore your car means the car is yours. You’re car translates into “you are car,” which makes no sense and reflects a grammatical error.
Similar rules exist for using It’s and Its. 使用 It's 及其 Its 存在类似的规则。
Its is a personal pronoun. It also describes ownership.
It’s is a contraction and an abbreviation for it is.
It’s 是 It is 的缩写
Its leaves are green, refers to the leaves belonging to the tree. It’s leaves are green translates into “it is leaves are green” or “ it has leaves are green,” neither of which makes sense in a sentence or is grammatically correct.
它的叶子是绿色的，是指属于树的叶子。它的叶子是绿色的，翻译成 “它是叶子是绿色的” 或 “它的叶子是绿色的”，这两者在句子中都没有道理，或者在语法上都是正确的。
Apostrophes are used with singular and plural possessive nouns.
For nouns that are singular and possessive the apostrophe goes before the s.
Ex. Mike ’s uniform.
For nouns that are plural and possessive, the apostrophe goes after the s.
Ex. The track teams’ uniforms.
Semi colons 分号
Semi colons connect two clauses that can otherwise be used independently. These clauses would be grammatically complete enough to function as two separate sentences, but you might want one sentence so there’s no break in the flow. (When reading two sentences there’s a natural pause that occurs between the first and second sentence.) You may not want that pause. You might want to connect them or highlight their contrast which is more effective with a semi colon.
Connecting clauses with a semi colon: 分号用于两个子句的连接
“I’m an excellent driver; I obey the traffic laws at all times.”
Semi colons are also used when making a list of items that are connected with a comma. 在列出用逗号连接的项目时，也会使用分号。
Ex.The trip includes stops in Los Angeles; California, London; United Kingdom and Paris; France.
