       This is one of the most favorite games among children. To play this game we should make 26 cards. On

  each of these cards we write an English letter. And here is an example to show you how we play it:

       First, before we start to play,  we decide what the game will be about. For example , we choose to play

  flowers.

       Next, one of us will mix the cards and turn over the one on top of them. If the letter on the card happens

  to be R, we will try to think of a flower which begins with R, like rose, as  quickly as we can.

  Then the one who first gives the name of the flower will win the card with R on it. This is done with each of

  twenty-six cards.

       In the end the person who has more cards wins the game.

Please put the pictures above in the right order.

1. __________        2. __________

3. __________        4. __________

5. Now let's play this game. If we choose to play colors, and you happen to get the card with B on it,

what word can you think of?

A. Beautiful

B. Color

C. Brown

D. Bread
