Когда нужно ставить ''is'' а когда ''are'' ?

Is - с существительными и местоимениями единственного числа. Например, he/she/it/Tom/A dog/ is

are - с существительными и местоимениями множественного числа. Например, we/they/you/parents/dogs are

She doesn't like drawing, so no papers, pencils or paints as presents (можете нарисовать листок и рядом краски и перечеркнуть это крестиком). She doesn't like dolls (нарисуйте куклу и перечеркните ее). She doesn't like flowers (нарисуйте цветы и перечеркните их).

Life for me is the greatest treasure you can ask for. It is a chance to shine and make a difference. We are so lucky to be alive, so lucky to be given this opportunity to experience all the magic of it. 
In my opinion, there is a reason for our existence. Our major purpose is to discover it and make everything possible to reach it. While living we have to go through many challenges, followed by joy. We have to face the storms in order to get a piece of the rainbow. But everything we do is totally worth it because only after falling a hundred times you can affirm you've lived. Some people believe they are here to write the history, others think it's their role to make the world a better place. Some guess they are useless, others find happiness in all the simple things. I know that my purpose now is to follow my dreams. It is the only path that can lead me to my real self and show me what is there for me to achieve going through this beautiful life.
Therefore, I believe that life is truly a gift and we've got to make the best of it.
