英文小作文：

Assumptions are a common part of life, whether it"s accepting responsibility for our actions, assuming authority over a task, or taking on a new role within a company or family. However, assumptions can be dangerous, as they can lead us to make incorrect conclusions about others or ourselves. Instead, we should rely on facts and evidence to make informed decisions. At the same time, we should also be more assumptive about our abilities and potential, for this can help us to push beyond our limitations and achieve our goals. In conclusion, assumptions are a necessary part of life, but we should always be mindful of their potential risks and use them judiciously.
