What are the most essential English phrases for travelers?

Yes, it is the opposite here! In the US, we go from small to large. Here is a typical address: 123 Main Street, Apartment 4B, Springfield, IL 62704. That is: street number and name, apartment number if any, city, state abbreviation, and ZIP code.

是的，这里正好相反！在美国，我们从小到大写。这是一个典型地址：123 Main Street, Apartment 4B, Springfield, IL 62704。也就是：街道号和街名、公寓号（如果有的话）、城市、州缩写和邮编。

💡 美国地址的核心格式：门牌号 + 街道名 / 公寓号 / 城市, 州缩写 + 邮编。州缩写是两个大写字母（如 IL = Illinois, CA = California, NY = New York）。

IL stands for Illinois. Every state has a two-letter code: CA is California, NY is New York, TX is Texas, FL is Florida, and so on. You can look them up online or just ask. And yes, ZIP code is basically our version of a postal code — it is a five-digit number that identifies a specific delivery area.

IL 代表 Illinois（伊利诺伊州）。每个州有一个两字母代码：CA 是加利福尼亚，NY 是纽约，TX 是德克萨斯，FL 是佛罗里达，等等。你可以在网上查或者直接问。是的，ZIP code 基本上就是我们版本的邮政编码——是一个五位数字，标识特定的投递区域。

💡 美国人通常能背出自己所在州和常见州的缩写。最常用的：CA（加州）、NY（纽约）、TX（德州）、FL（佛州）、WA（华盛顿州）。注意 WA 是华盛顿州，DC 是华盛顿特区。

Good question! The apartment number goes on the same line as the street address, or on a second line. You can write it as Apt 4B, Unit 4B, or just #4B. For example: 123 Main Street, Apt 4B Springfield, IL 62704 The most important thing is that the apartment number is clearly visible so the mail carrier can find you.

好问题！公寓号和街道地址写在同一行，或者写在第二行。你可以写成 Apt 4B、Unit 4B，或者直接 #4B。比如： 123 Main Street, Apt 4B Springfield, IL 62704 最重要的是公寓号清楚可见，这样邮递员能找到你。

💡 如果不写公寓号，包裹可能退回或送到错误的地方。在美国，邮递员（mail carrier）通常把邮件放在信箱里，不会送到门口。公寓号是他们找到你信箱的关键。

Perfect! That is exactly right. One more tip: when you write it on an envelope, the sender's address goes in the top left corner, and the recipient's address goes in the center. And always include your return address in case the package cannot be delivered.

完美！完全正确。再给你一个提示：写在信封上时，发件人地址写在左上角，收件人地址写在中间。而且一定要写回寄地址，以防包裹无法投递。

💡 Return address（回寄地址/退回地址）是美国邮件的重要部分。如果收件人搬家或地址错误，邮局会把邮件退回发件人。没有回寄地址的邮件如果无法投递可能被销毁。

Easy! Address Line 1 is your street address — like 456 Oak Avenue. Address Line 2 is for the apartment, suite, or unit number — like Apt 12C. If you do not have one, just leave it blank. City is Austin, State you pick Texas or TX from a dropdown, and ZIP is 78701.

很简单！地址行1是你的街道地址——比如 456 Oak Avenue。地址行2是公寓、套房或单元号——比如 Apt 12C。如果没有，留空就行。城市填 Austin，州从下拉菜单选 Texas 或 TX，邮编填 78701。

💡 很多网站的 State 字段是下拉菜单（dropdown），你只需要选择。ZIP code 必须是五位数字。有些网站会自动根据 ZIP code 填充城市和州。

Great question! Here are the most common ones: St is Street, Ave is Avenue, Blvd is Boulevard, Dr is Drive, Ln is Lane, Ct is Court, Way stays as Way, and Rd is Road. You will also see N, S, E, W for North, South, East, West. So 456 N Oak Ave means 456 North Oak Avenue.

好问题！最常见的有：St 是 Street（街），Ave 是 Avenue（大道），Blvd 是 Boulevard（林荫大道），Dr 是 Drive（驱车道），Ln 是 Lane（巷），Ct 是 Court（庭），Way 不变，Rd 是 Road（路）。你还会看到 N、S、E、W 代表 North、South、East、West。所以 456 N Oak Ave 意思是 456 North Oak Avenue。

💡 方向（N/S/E/W）在美国地址中很重要——456 N Oak Ave 和 456 S Oak Ave 是完全不同的地方。填写时不能省略方向。

PO Box stands for Post Office Box. It is a mailbox you rent at the post office. Some people use it for privacy or if they move a lot. The address would look like: PO Box 789, Springfield, IL 62704. C/O means care of — you use it when sending mail to someone at another person's address. Like: John Smith, C/O Jane Doe, 123 Main St, Springfield, IL 62704. It tells us to deliver to Jane's address but the mail is for John.

PO Box 是 Post Office Box（邮政信箱）。是你在邮局租的信箱。有些人为了隐私或经常搬家会用它。地址看起来像：PO Box 789, Springfield, IL 62704。C/O 是 care of（转交）——当你寄信给住在别人地址的人时使用。比如：John Smith, C/O Jane Doe, 123 Main St, Springfield, IL 62704。它告诉我们送到 Jane 的地址，但邮件是给 John 的。

💡 C/O（care of/转交）对新移民特别有用——刚到美国可能暂住朋友或亲戚家，用 C/O 可以确保邮件送到正确的人手里。很多政府文件和银行卡也可以寄到 C/O 地址。
