AT THE GoZeroWaste workshop in Suzhou, a canal town near Shanghai, a dozen young people learn to hand-sew face masks. The single-use, surgical sort are hardly in short supply, as no country makes more masks than China. 是由于承前省略的原故么？Masks of the single-use, surgical sort...？谢谢各位老师。
在作者心目中，The single-use, surgical sort are =Masks of the single-use, sugical sort are.
COCA例句： Your sort are always going on about your petty sufferings.
= People of your sort are...
