He studies Computer Science.(The present simple)

He studies Computer Science.

• Subject-verb agreement

  • In English, the subject of a sentence must agree with the verb in number.
  • If the subject is singular, like he in this sentence, the verb must also be singular.
  • Hence, the use of studies instead of study.

  Example: He studies Computer Science.

  
  
• Proper use of articles

  • In English, the, a, and an are articles used before nouns.
  • However, they are not used before names of subjects or disciplines unless it is a specific case.

  Example: He is studying the science of computers.

  
  
• Capitalization of proper nouns

  • Names of subjects or disciplines are usually not capitalized unless they are part of a degree title or used in the title of a class.
  • However, Computer Science is capitalized here to show it is a specific course or field of study.

  Example: I am studying Computer Science.
