At present, the internet was attend in our daily routines.
This idea comes nowhere. Also, you need to write this present tense, not the past one.
Let me give a try: It is true that the Internet affects the way people live.
In addition, people's lives more easier due to the internet.
Again, this contains a grammatically incorrect sentence
Let me give a try: This helps people live more easily.
I more likely to believe that the internet give an ease in various activities.
This sentence has been discussed in the previous ideas. You do not need to include this unless the sentence is redundant.
This essay would stand to propose my proponent to the notions of broaden horizon and easier with communication.
This sounds more complicated. It is always better to use PLAIN ENGLISH rather than BIG WORDS that you do not 100% understand how to use it properly.
As you can see, some changes have made. More attention should be paid on how to provide a very good introduction, since it is your stepping stones to the next paragraph. If you fail here, then I am sure you are in trouble.
Hope this helps :D
A heap of luck
