The homework was there, but it __________________ (WRITE) carelessly and obviously contained lots of mistakes.

“I wish Thomas Edison __________________ (CAN) see how his invention affects some people.” Jack’s mother said. “Who’s Thomas Edison?” asked Jack.

One day, in class, the teacher asked the students who Thomas Edison was. Jack answered at once: “He was the __________________ (ONE) man who gave people the opportunity to watch television without candlelight.”

“I __________________ (DO) my homework already!” Jack announced and turned back to the screen. His mum had a look at his exercise books.

Naturally, the next day he __________________ (WAKE) up late and went to school without doing his homework.

At last his mother said: ‘You can only watch TV when you’ve done your homework.' However, half an hour later, when she entered the room, she saw that Jack __________________ (WATCH) TV!

He said: “I __________________ (BE) too tired. I’ll get up early tomorrow to do my homework”.

“A great scientist. He studied electricity and he invented the light bulb to light our houses. Television wouldn’t be possible without __________________ (HE).”

«Jack always put off his homework because he wanted to watch television. At first his mother let him do this. However, after watching television, Jack __________________ (NOT/WANT) to do anything either.»
