As he unfastened his shirt a scrap of paper slipped from it and fluttered to the floor.

他解开衬衫时，一张纸片从里面滑落，飘落在地板上。

I’d probably prop up proper pop-up purple paper people with a proper pop-up purple people paperclip, but I’d pre-prepare appropriate adhesives as alternatives, a cheeky pack of Blu Tack just in case the paper slipped.

我也许能弹起合适的弹立式的紫色纸片人，利用合适的弹立式的紫色纸片人夹子，我要提前准备好合适的胶水作为备用，一大堆蓝丁胶，以防纸片滑到。
