It’s not. Here are some tips on how to put objects in boxes.人们将收拾上大学所需的物品当作人生大事,就像结婚一样。下面是如何收拾物品的建议。Step 1: Learn what you can't bringFind out what items you’re not allowed to bring.

Some objects you only need one of.联系室友联系未来的室友来讨论下你们各自要带的东西。有些物品只需有1个即可。Step 3: Start with basicsStart with the basics: bedding of the proper size, a towel, toiletries.

Pack accordingly—sometimes it’s better to be without an object than to have something that’s embarrassing.小贴士:去大学时一个改变身份的特别机会。收拾的原则是宁可没带也不要带让你尴尬的东西。Step 5: Consult packing listConsult a packing list to remind yourself what else to bring. Your school probably sent you a list, and there are plenty online.看下行囊清单看下行囊清单来提醒自己还需要带什么其他东西。你的大学很可能会寄给你行囊清单,网上也有很多。Step 6: Pack lightPack as few heavy objects as possible.
