Traanf THUThere are many sample answers on the internet make me confused.

I agree. There are many IELTS teachers with websites and they have different styles and they give different advice. It is very confusing.

I have looked at quite a few of them, and some of them are very good, and others are horrible. Many are not written by native English speakers.

The major problem for task 1 is that they do not have a math or science background, so they write a math/science essay as if it were going to be used for a newspaper article or blog post, not for a university lecturer! The vocabulary advice is quite bad.

For example, they might write. "The proportion of internet users experienced a downturn in 1998."

Well, proportion is a quantity, a number. Numbers cannot see and cannot have experiences. The ones in the cartoon below do, but is that appropriate for a university physics professor?
