请问其中的数量30 set 要怎么加在句子中？ 1.We are pleased to inform you that your inquire goods for in stock at present.
2.We will send these goods to you by airfreight on next week.
3.You had inquired the item of product No. 9335-3221 on last time, this product for in stock now, we will send you to go along with by this airfreight cargo.
「缺货」的表示法 inquire是「询问」，但其实对方是跟你要这项产品，不是问问而已，所以可以改成「要求」request。 We are pleased to inform you the product you requested is now in stock.
「有货」如你所写的，是in stock，「缺货」则是not in stock： We regret to inform you that these items are not currently in stock.
「空运」、「海运」怎么说？ 「空运」airfreight也可以用air cargo表示： We will ship these goods by airfreight next week.
These items will be shipped to you by air cargo early next week.
平平是「空运」，airmail跟前两者有什么差别？airfreight和air cargo运的是大型货物，airmail则是寄送小型信件或邮包： The sales contracts have been sent by airmail.
至于「海运」sea cargo有时也会说surface cargo，但surface cargo其实包含「海运」及「陆运」，也就是「海陆联运」： These items will be shipped by surface cargo early next week.
We want to order one container by sea cargo.
上面说到sea cargo跟surface cargo的差别，同理可知当你透过海运寄送小量的货物时，也可以用surface mail表示。 至于你最后一个问题：30 sets要怎么放进句子里，以下是我们建议的写法： The item you requested earlier, 30 sets of product No. 9335-3221, is now in stock.
We will send both orders together by airfreight.
inquire (v.) 询问 Please inquire as to what time the boat arrives. 请告知船到达的时间。
request (v.) 要求 The audience requested that the band sing a popular song. 观众要求乐团唱首流行歌曲。
in stock 有存货 A: I’m looking for your new power drill. 我要找你们新型的电钻。 B: Sorry. We don’t have any in stock right now. 抱歉。我们现在没有存货了。
