As the matter of fact, she was a person who hard being convinced for instant, she certainly would likes to thinks that his opinion are the corrected then any one else view.
1. Article usage: Only use “the” to refer to specific items; for singular non-specific items use “a”, e.g. a matter of fact.
2. Word form: although the sound is similar, don’t confuse “instant” with “instance”--the meanings are quite different.
3. Passive form: “hard being convinced” seems to be a passive construction, but the form is incorrect--hard needs to be introduced by “was” and followed by an infinitive (was hard to convince).
4. Verb form: After a modal verb, use the verb name--“like” not “likes”.
5. Infinitive: The infinitive is formed from “to” + the verb name--there is no “s” or any other verb ending on an infinitive, so change “to thinks” to “to think”.
6. Pronoun agreement: it makes better sense to change “his” to “her”--“his” is possible, but it just doesn’t make as much sense.
7. Word form: “corrected” is a past participial adjective; here comparison is needed--more correct. A good correction would be change this expression to “better”.
8. Word confusion: “then” and “than” often sound alike, but there meaning and function is quite different; here you need “than” because there is an implicit comparison.
9. Possessive: “view” belongs to someone--here “anyone else”, so it needs to be possessive (anyone else’s).
10. Punctuation: The first independent clause ends with “convince”; a semicolon is needed here.
Possible Answer: As a matter of fact, she is a person who was hard to convince; for instance, she certainly would like to think that her opinion is better than anyone else’s.
