SAGE网站上说的话，请各路大神给分析下：
What should I do if I cannot pay the article processing charge (APC)?
If you cannot pay the APC, consider publishing in any SAGE subscription journal and depositing the article in your institution’s repository under SAGE’s green open access policy.
If you wish to publish in a gold open access journal, check if you are eligible for any discounts. Some journals may consider waiver or discount requests - see our waiver and discount policy  for more details. Please note that discount and waivers requests are only considered after acceptance of the article，
