positive和optimistic有什么区别？

虽然“positive”和“optimistic”这两个词都表示积极的态度，但它们在使用上还是有一些细微差别的。

“positive”通常指的是对事情本身的态度积极，即能够看到事情的好处，具有建设性，而不会被现实的困难所打败。例如，“i have a positive attitude towards this new project.（我对这个新项目有积极的态度。）”

“optimistic”则更强调对未来的期望和信心，是一种伴随着乐观主义的积极态度。例如，“despite the challenges we face, i remain optimistic about our chances for success.（尽管我们面临挑战，但我仍然对我们成功的机会感到乐观。）”

可以说，“positive”是一种对事物本身的评价，而“optimistic”则是一种情感色彩更浓厚的态度，与人的主观情感和期待密切相关。
