据美国赫芬顿邮报报道，盛夏来临，想挑选一个好西瓜消暑却并非易事，美国赫芬顿邮报列出3招辨别西瓜好坏的方式。
观看西瓜外皮斑点
西瓜成熟的秘密有部分被表现在外皮上，好的西瓜外皮上带有淡淡的黄色斑点，代表西瓜是在太阳底下熟成，如果没有淡黄色斑点，就应该考虑。
感受西瓜重量
越重的西瓜品质越好。赫芬顿邮报称，西瓜是好是坏，可以捧在手上确认，如果捧起来的重量比目测感觉的重量还重，那么就是个好西瓜。
敲击西瓜
敲西瓜可能会被其他消费者侧目，但敲西瓜并听西瓜发出的声音，也可以确认西瓜的好坏。赫芬顿邮报称，如果发出的声音是沉重的“嗵”而不是“啪”，就可以知道这是一颗好西瓜。
部分原文报道如下：
Purchasing a watermelon is kind of a risky investment. It's usually giant, so you're really committing to a lot of fruit. And the thick green rind protecting the pink flesh means there's no easy way to know how good the fruit is inside. Or is there?
If you know what to look for, you can be sure of a watermelon's readiness before cracking it open. Here's what you need to know:
Look for the spot. The telltale sign that a watermelon is ready to be sliced open is the spot. A good watermelon will have a pale yellow spot on the rind, indicating that it was left on the ground to ripen in the sun. If there's no yellowish marking, be wary.
Make sure it's heavy. Another sign you've got a good melon on your hands is the weight. If you pick up the watermelon and it feels really heavy — heavier than it looks — you've hit the jackpot. The heavier the melon, the better it is.
Knock on it. Sure, you might get a little side eye from other grocery store shoppers, but give the melon a listen for a final test. Gently knock on the watermelon and listen for a hollow sound that makes a “plunk” rather than a “thwack” sound.
