Which three letters can frighten a thief away?
Think of words ending in "gry." Angry and hungry are two of them. There are only three words in the English language. What is the third word? The word is something that everyone uses every day. If you have looked carefully, I have already told you what it is.以「gry」結尾的詞，比如Angry and hungry 生氣和飢餓是其中的兩個。那麼問題來了，「在英語」里有三個詞，第三個詞是什麼？這是我們每天都要用的一樣東西，如果你仔細看的話，我已經告訴你了。
【單詞】
you will find it in school，in broken clocks，in snow，and holey socks.It is also in food and shoes，it is not in me，but it is in you，what is it？
