问题描述：
改错：if you would buy one box at the regular price,you would receive anothe
答
if clause的三种虚拟结构如下：
if sb. did/were sth, sb. would/could/should/might.......do sth (与现在相反）；
if sb. had done sth, sb. would/could/should/might.....have done sth (与过去事实相反）；
if sb. did/were to do/ should do sth, sb. would/could/should/might.......do sth (与将来相反）。
所以以上句子我们可以这样修改：if you should buy one box at the regular price,you would receive another。
one box和 a box都是泛指一个，意义一样的。
答
if you buy a box at a regular price,you would receive another one.
答
‘if you would 、、、’if从句引导条件状语从句,不需要would.去掉.
‘one box’表示泛指,这里应该是改成表个数的 a
‘the regular price’这里译为‘普通价格’应该是‘一个普通的价格’购买,不应该是特定‘那个普通价格’购买.the也换成a.
