According the meaning which you are trying to express here, you should use 'couldn't have gone' and the correct sentence would be:
"I think he couldn't have gone abroad. I saw him just now."
You are right that 'couldn't have gone' shows a possibility but that i what you are trying to say. You didnt knew before seeing him that he has gone abroad or not. And you were not sure too. So that is why you said 'couldn't have gone'.
I hope it helps.

Yes, Mayank is right. " I am fond of " is correct.

No. In this sentence the word 'stress' cannot be replaced by 'pressure'. Very well explained by Brad.
There is a mistake in the sentence also. The spelling of 'then' is wrong. It should be 'than' as you are comparing two things here.

well in the passage you can write about how you can protect the environment. for example by planting trees, clean your house,school, street, avoid throwing garbage on the road etc.
