Try to translate the following into Chinese .10.The makers of the Constitution knew that changes would be necessary and that if there was no way of making them, the Constitution would no longer be useful. They, therefore, made it possible for Americans to change the Constitution by adopting amendments to it, but they did not make it easy to do so.
宪法制定者早就意识到修改是必要的，如果无法对其修改，宪法将不能长期发挥作用。因此，他们通过采纳修正案使美国人有可能更改宪法，同时他们也使之不能轻易改变。
