阅读短文，回答问题Max and Holly sat beside each other in a classroom. Their teacher Miss Carr stood at the front of the classroom and looked at them with a strange stare. "Silence!" Miss Carr shouted. "You're only allowed to speak if you want to say "I'd like to do extra hard MATH", understand? "
Then the bell rang for lunchtime and everyone jumped to their feet. "Sit down!" shouted Miss Carr. Everyone did as they were told. Miss Carr held up some sheets of paper. "These are new school rules, written by our wonderful new headteacher, Mr. Roberts, " she said. "You must do exactly as they say from this moment on. I want everyone to take a copy for your parents."
"Look at this!" Max said, reading the first line. "Rule one: No pupil will be allowed to go out at playtime unless they have passed a daily spelling test." Max and Holly then continued to look at the other new school rules.
"Rule two: We're not supposed to be in here at lunchtime."
"Rule three: Pupils must eat cabbage stew or sprout surprise for lunch."
"Rule four: All P. E. will now take place outdoors—no matter what the weather is."

"Something's wrong." said Holly, "Things have been strange ever since Mr. Roberts took over as our head teacher last week. We need to find out what's going on."
Then Max and Holly walked to the teachers' office and stepped inside, surprised to find that many teachers have been tied up in the room! From their words, Max and Holly knew that the teacher in the classroom just now was just a robot clone (克隆) and she was not real Miss Carr, even the new headmaster! Max and Holly then succeeded in freeing all the teachers trapped.
"We'll deal with those rotten robots!" said one of the teachers, as they ran out of the room.
"How can I ever thank you, Max?" asked the real Miss Carr.
"How about no homework for the rest of the school year."
Finally, Max and Holly realized that the school rules made by their real headmaster were so nice.
