Проверьте грамотность и предлоги, формулировку there are many animals on the world. but i`d like to tell you about my favourite one. it is wolf. i`m really admire for its beauty and grace. there are many kinds of wolves, which have differents in their appeance, for example in colour. but i`m like this animals not only by its appearance, i`m wonder for their intelligance and devotion to their pack. once, i saw wolves`s hunting on tv. it was emazing! i marvel their speed and endurance. they can silently stalk prey like a shadow. if someone`ll ask me whether i would like to become in the next life, i`ll have chosen wolf.
не differents, а differences.
не I'm like, а I like. и там же I wonder
опечатка intelligence
wolves'
скорее всего нужен артикль "a" тут - a prey
вроде после if нельзя will писать. тогда не will ask, а asks, хотя мне кажется вообще это предложение лучше переделать так:
If someone asks me who I would like to become in the next life, I`ll chose a wolf.
