Scrabble(拼字游戏) is a game I like most, but it is not an easy one. Henry, Tom and I are going to play Scrabble tonight. Henry cannot remember all the rules, so I will explain them. Do you want to learn? Listen carefully,and we will play later.Each player takes seven letters. Your letters might be A, S, T, E, B, P and L .You can spell many words with these letters. You can spell TABLE with five of them, and you can spell LAP, LET, SAT, BAT and others with three of them. But you cannot use names of persons, countries, or cities.You have to be careful. Some letters are worth more points than others. For example. A, E, L, S, and T have one point each, B and P have three points each. The number of points can be different for words with the same number of letters. SAT will give you only three points, and BAT will give you five. TABLE will give you seven points; three for B and four for the other four letters. Use TABLE. You will get more points, and you might win the game.At the end of the game the players add up their points. The one with the most points wins. For example, you might have one hundred and forty points. That is a good score. But I might have one hundred and sixty points, and Henry might have one hundred and seventy points. Then Henry wins.
