It’s hard to deny that some Internet addicted people spend too much time on line and ignore family, friendships, and social activities. However, it’s not that they don’t have fun on the Internet or use it for their profession. It’s just not overusing it.

Distinguishing between facts and opinionsFacts are things known for certain to exist, or be true, or have happened. Opinions are things believed to exist, be true, or have happened. The key difference b

etween facts and opinions lies in the difference between knowing and believing. Opinions may be based on facts, but they are still what we think, not what we know for certain. Opinions are debatable; facts are not.

Presentation of the skill

Distinguishing between facts and opinions

A simple way is to ask questions like “Is this statement debatable?” and “Is this known for certain to be true?” If you answer “yes” to the former question, it is an opinion; if you answer “yes” to the latter question, it is a fact.

Presentation of the skill

Distinguishing between facts and opinions

The above two examples are about the author’s judgment or opinion. Although the statements are based on facts (e.g. “many schools offering wireless Internet access anywhere on campus” and “the widespread application of laptops and computer science”), they still show how the author thinks or feels, so they are not facts.

Presentation of the skill

Distinguishing between facts and opinions

In Example 1, the word most shows us that this is the author’s opinion or assumption. In Example 2, the sentence “we are going to produce a generation of…” indicates that this is what the author predicts or hopes, not something that exists or has happened. Therefore, the statements are opinions.
