should work at least half an hour at a time without stopping.

happening each day in school, will take the fear out of tests and keep you on top of it.

Foolish(silly) Freddie lived in a small village. The people of the village laughed at him. They liked to show visitors how silly Freddie was. They thought this was a funny thing to do.
One day, a visitor came to the village.
"Watch this", a villager said, and called to Freddie. "Come and play a game, Freddie, " he shouted. Freddie walked slowly towards him, a silly smile on his face.
"Look! Freddie, "the villager said, "I’ve got something for you." He showed Freddie a dollar coin and a much larger 50-cent coin."Which would you like?" he asked Freddie.
Freddie took the 50-cent coin at once.
The villager laughed."See how foolish he is," he said."He always does that. He’s too silly to learn anything." He walked away, leaving Freddie with the visitor.
The visitor felt sorry for Freddie and said to him, "Although the 50-cent coin is bigger than the$1 coin, the$1 coin is worth(值) much more.Two times as much."
"I know that," Freddie said."But once I take the$1coin, they’ll stop playing the game."
