XIV. Are you up to giving a right explanation?

It's a sort of a game, the game that develops student's abilities to express themselves. In some ways it helps students to plunge into English.

One of the students, a volunteer, is invited to take place at the teacher's table. He is facing the class and mustn't turn back and look at the blackboard. The other student with the rest of the company picks secretly out one of the statements given in this book and writes it on the blackboard.

Now the volunteer after getting some information from his colleagues tries to restore the statement.

The information concerns:

• The number of words;

• the main idea of the statement, if possible;

• the meaning of each word of the statement. It is strictly prohibited to use the words written on the blackboard, but it is quite well to use synonyms and antonyms.

It's extremely desirable that everybody takes part in this game.
