Comparative Form

I've already posted about Comparative forms before, but due to students asking for more, here you are:
When you want to compare one thing (or person, place, whatever) to another, you must use this form, but for short adjectives you just add -er + than. Examples:
 - Sheila is taller than Samantha.
- Bill Gates is older than Mark Zuckemberg.
- Usually, a dog is bigger than a cat.
- This room is cleaner than that one.

When you have longer adjectives, you add more + adjective + than. Examples:
- A smartphone is more modern than the majority of the cell phones.
- Buying brand name clothes is more expensive than buying popular ones.
- Travelling by plane is more comfortable than traveling by bus.
- That test was more difficult than the first one that I did last semester.

So, if you click on Ego4U , Better English Lessons and Englisch-Hilfen, there are more activities. Hope to have helped you! Remember that, before everything, English is self-study, so work on it!
