英文小作文：

The topic of euthanasia is a highly controversial issue that has sparked debate and discussion among people around the world. While some people believe that euthanasia should be legalized and regulated, others argue that it should be prohibited or restricted. In my opinion, euthanasia should be voluntary and patients should have the right to refuse it, while still being supported by family and friends. However, it is important to ensure that euthanasia is carried out in a safe and legal manner, and that it is only used as a last resort when all other treatment options have been exhausted. Ultimately, the decision to end life should be made by the individual, but with the guidance and support of medical professionals and family and friends. This approach would ensure that euthanasia is used appropriately and ethically, while also respecting the rights and choices of individuals facing difficult situations.
