学生英语有没有复数怎么说

Yes, in English, students can be referred to as a plural noun, which means there is more than one student. To form the plural of a noun in English, you usually add -s to the end of the singular form of the noun. For example, the plural of "student" is "students."
Here are some examples of the word "students" being used in a sentence:
There are 50 students in my class.
The students are working on a group project.
The teacher asked the students to turn in their homework.
It's worth noting that there are a few exceptions to the rule for forming the plural of nouns in English. For example, some nouns form the plural by adding -es to the end, such as "boxes" (plural of "box") or "dresses" (plural of "dress"). There are also a few nouns that have irregular plurals, such as "child" (plural "children") or "tooth" (plural "teeth").
