本文是一篇关于cloning的作文，内有十处错误，请找出并改正。
You can read the word "cloning" quite often on the newspaper. I find it very interested. It seems like a fairy story. With cloning you will be copied. Today, scientists can clone any large animals. Doctors are in the process of cloning humans, though it is not allowed in most of the country. Cloning brought a lot of questions. If someone can come the world with only one parent, will he or she be happily? My grandmother died a few years before. I miss her very much. If she can be cloned into a new one, I'll be very happy but confused. How shall I call her after she comes into the world? Because "she -- my grandmother" is more younger than I.
