关于梦想的英语开头和结尾可以有多种表达方式，以下是一些例子：

开头

I have a dream, I want to be a doctor when I grow up.

Dream is the starting line of our actions, knowledge is our forward accelerator, we insist that it is a non-stoppace, wisdom is our key to success.

Fear not that the life shall have an end, but rather fear that it shall never have a beginning.

结尾

I believe I must come true my dream.

With hard work and determination, my dream will come true one day.

The pursuit of a cause can make us “dream” of doing higher.

这些开头和结尾都可以根据具体的语境和需要进行选择和调整，以更好地表达关于梦想的主题。
