It's going to be 95 degrees this weekend. Stay hydrated!

这周末要95度。记得多喝水！

💡 美国用华氏温度（Fahrenheit），不是摄氏。快速换算：(F-32)×5/9=C。常见参考：32°F=0°C（结冰），72°F=22°C（舒适），100°F=38°C（酷热）。刚到美国听到 '95 degrees' 别以为要被煮了。

Ha, yeah — 95 is really hot! That's about 35 Celsius. Here's an easy trick: if it's in the 70s, it's nice. 80s, warm. 90s, hot. Below 32, it's freezing — literally!

哈哈是的——95度真的很热！大约35摄氏度。教你个简单方法：70多度很舒服，80多度温暖，90多度很热。32度以下就结冰了——字面意义上！

💡 'In the 70s' 表示70-79度之间。美国人谈天气经常用这种范围说法。32°F 是水的冰点——freezing point。

That's the 'heat index' — it factors in humidity. So the actual temperature might be 90, but with high humidity, your body feels like it's 100. It's brutal in the South!

那是'酷热指数'——把湿度算进去了。实际温度可能是90度，但湿度大的话身体感觉像100度。在南方特别要命！

The store is about 2 miles from here. We could walk, but it'd take about 40 minutes.

店离这大概2英里。我们可以走，但要大约40分钟。

💡 1 mile ≈ 1.6 km。快速估算：英里数 × 1.5 + 10% ≈ 公里数。2 miles ≈ 3.2 km。美国人说距离永远用 miles，说 kilometers 会被看成外星人。

Good call! Oh, and I need to pick up a 5-pound bag of flour. Do you know how much that is in kilos?

好主意！对了，我要买5磅的面粉。你知道那是多少公斤吗？

💡 1 pound ≈ 0.45 kg。5 pounds ≈ 2.3 kg。美国超市的面粉、糖、米都按磅卖。常见包装：1磅、2磅、5磅、10磅、25磅。

Close enough! 2.3 kilos to be exact. Here's a fun one — how tall are you? In the US, we use feet and inches.

差不多！精确是2.3公斤。来个好玩的——你多高？在美国我们用英尺和英寸。

💡 美国身高用 feet(英尺) 和 inches(英寸)。1 foot = 12 inches = 30.48 cm。常见换算：5'4" = 163cm, 5'7" = 170cm, 5'10" = 178cm, 6'0" = 183cm。
