我的中文是：當好朋友生日時，我和其他朋友們會偷偷做卡片給他幫她慶生。 我翻：When friends birthday, I and other friends will He secretly made cards to help her birthday 這樣對嗎?

Some friends and I will make a card secretly for her birthday .

When friends birthday, I and other friends will He secretly made cards to help her birthday. (X)
Friends and I make birthday cards (in secret) for our birthday celebrations. (O)

還要偷偷做喔? 好令人吃驚耶!
