🌧 打字雨Word Rain
在线打字练习小游戏“打字雨”：英文字母和单词像雨滴一样落下，在输入框里打出完整单词就能消掉它，掉到地上会失去一次机会，越往后落得越快。可选键位字母、短单词和长单词三种模式，单词下方可显示中文释义，同时练打字速度和英语单词。Word Rain typing game online: letters and English words fall like raindrops and you clear each one by typing it in full; any that hit the ground cost a life, and the rain speeds up as you go. Choose home-row letters, short words or long words, and optionally show the Chinese meaning under each word — practise typing speed and vocabulary at once.
在输入框里打字：与正在输入内容开头相同的单词会变蓝，打完整个单词就会自动消掉，按回车或空格可以清空重打。Esc 暂停。Type in the box: words starting with what you've typed turn blue, and a word disappears as soon as you finish it. Press Enter or Space to clear and retype, Esc to pause.
玩法说明与常见问题How to play & FAQ
「打字雨」怎么玩？How do I play Word Rain?
点击「开始」或直接在输入框里打字就会开始下雨。每个落下的雨滴上写着一个字母或英文单词，打对后它会消失并加分（单词越长分越多）。雨滴落到草地上就会失去一次机会，5 次用完游戏结束。分数越高，雨点落得越快、越密。“键位字母”模式从基准键位开始，逐渐加入其他字母，适合打字初学者。Press Start or just begin typing and the rain starts. Each raindrop carries a letter or English word; type it correctly and it vanishes for points (longer words score more). Any drop that reaches the grass costs one of your 5 lives. The higher your score, the faster and denser the rain. Letters mode starts with the home row and gradually adds other keys, which suits beginners.
手机上能玩吗？Can I play on a phone?
可以。点一下输入框就会弹出手机键盘，打字方式和电脑一样；建议选择“短单词”模式。Yes. Tap the input box to open your phone keyboard and type as usual; the short-words mode works best on phones.
WPM 是怎么算的？How is WPM calculated?
WPM 是每分钟打出的“单词”数，按照通行算法每 5 个字母算一个单词，只统计打对并消掉的内容。WPM is words per minute, counting every 5 letters as one word as is standard, and only text that cleared a drop counts.
