These sample sentences. "Those" means somewhere else or before or above. "Example" means a model for others to follow. Use "sample" when you are giving a sample of your writing. "human's" is okay if there is only one human you are referring to and it is clear which one. If you mean that humans in general have complex mentalities you might say Humanity's. "wants that toy so much" is better. We are already in the 10th month (or in October). Even through my grandmother didn't know a single English word (or any words in English), she traveled to America.

The first sentenses seen ok. In the following one I would change the order: "That kid wants that toy so much that he cries loudly on purpose" "We are already on the 10 month, it has clearly become cooler" - I didn't get what you meant here. "Inspite of the fact that my grandmother didn't know a word in English, she traveled alone to America"

The first two sentences are perfect. In the third, "human's complex mentality" does not sound natural, and it is not clear exactly what you mean by "mentality." The third would be better as: "The movie expresses very well the complexity of human mentality." The fourth should be: The kid wants that toy so much that he cried loudly on purpose. The fifth needs a conjunction to join the two clauses, and 10 should be 10th: We are already on the tenth month, and it has clearly become cooler. It the sixth, "if" should be "though": Even though my grandmother doesn't know any English words, she traveled alone to America. Good job!

-It's important to praise children's talents. -This food looks bad*, but tastes really good. {"bad" suggests spoiled, so "terrible" or "awful" is better} -This movie expresses very well *a* human's* complex mentality. {better: person's} -That kid wants *that toy so much that* he cried loudly on purpose*. {better: purposely threw a tantrum, purposely cried loudly} -We are already *into October*, it has clearly become cooler. {"in the tenth month would mean any ten months in the future.} -Even *though* my grandmother *didn't* know any *English words*, she traveled alone to America. Please let me know if there *are* any mistakes. Thanks in *advance.* :)
