网申是要求上传certificate

请问网申时候要求upload certificates, awards similar documents， 需要翻译成英文吗？还是原件就行呢？

求解啊～～～
You may upload Certificates, awards or similar documents.

Do not upload any materials such as writing sample, abstract, book review, portfolio, etc, those documents must be uploaded in the Supplemental Materials section.
Please use a margin of 1inch at the top of the page to allow room for the application system to automatically print your name and Applicant ID in that space. Click the Upload Document button below to attach it to your application.

The file you upload cannot exceed 20000kb (20mb) in size and should be in .wpd, .doc, .docx, .rtf, .pdf, or .txt format.

Also, please do not attempt to upload a document that is password-protected. This will cause the process to fail.
