????If you park your car in the wrong place, a traffic policeman will soon find it. You will be very lucky if he lets you go without a ticket. However, this does not always happen. Traffic police are sometimes very polite. During a holiday in Sweden, I found this note on my car:'Sir, we welcome you to our city. This is a?"No Parking" area. You will enjoy your stay here if you pay attention to our street signs. This note is only a reminder.' If you receive a request like this, you cannot fail to obey it!

like this????像這樣一樣（like prep. 介詞 像 ... 一樣）

cannot fail????不能辜負（雙重否定意思為肯定，cannot：不能，fail：辜負，使失望。不能使失望，不能辜負）
