Помогите пожалуйста ответить на вопросы к тексту.
Peter had wanted a Little Brother™ for three Christmases in a row.
His favorite TV commercials were the ones that showed just how much fun he would have teaching Little Brother™ to do all the things that he could already do himself.
But every year, Mommy had said that Peter wasn't ready for a Little Brother™.
Until this year.

This year when Peter ran into the living room, there sat Little Brother™ among all the wrapped presents, babbling baby talk, smiling his happy smile, and patting one of the packages with his fat little hand.
Peter was so excited that he ran up and gave Little Brother™ a big hug around the neck.
That was how he found out about the button.
Peter's hand pushed against something cold on Little Brother™'s neck, and suddenly Little Brother™ wasn't babbling any more, or even sitting up.
Suddenly, Little Brother™ was limp on the floor, as lifeless as any ordinary doll.

"Peter!"
Mommy said.

"I didn't mean to!"

Mommy picked up Little Brother™, sat him in her lap, and pressed the black button at the back of his neck.
Little Brother™'s face came alive, and it wrinkled up as if he were about to cry, but Mommy bounced him on her knee and told him what a good boy he was.
He didn't cry after all.

"Little Brother™ isn't like your other toys, Peter," Mommy said.
"You have to be extra careful with him, as if he were a real baby."
She put Little Brother™ down on the floor, and he took tottering baby steps toward Peter.
"Why don't you let him help open your other presents?"

So that's what Peter did.
He showed Little Brother™ how to tear the paper and open the boxes.
The other toys were a fire engine, some talking books, a wagon, and lots and lots of wooden blocks.
The fire engine was the second-best present.
It had lights, a siren, and hoses that blew green gas just like the real thing.
There weren't as many presents as last year, Mommy explained, because Little Brother™ was expensive.
That was okay.
Little Brother™ was the best present ever!

Well, that's what Peter thought at first.
At first, everything that Little Brother™ did was funny and wonderful.
Peter put all the torn wrapping paper in the wagon, and Little Brother™ took it out again and threw it on the floor.
Peter started to read a talking book, and Little Brother™ came and turned the pages too fast for the book to keep up.

But then, while Mommy went to the kitchen to cook breakfast, Peter tried to show Little Brother™ how to build a very tall tower out of blocks.
Little Brother™ wasn't interested in seeing a really tall tower.
Every time Peter had a few blocks stacked up, Little Brother™ swatted the tower with his hand and laughed.
Peter laughed, too, for the first time, and the second.
But then he said, "Now watch this time.
I'm going to make it really big."

But Little Brother™ didn't watch.
The tower was only a few blocks tall when he knocked it down.

"No!"
Peter said.
He grabbed hold of Little Brother™'s arm.
"Don't!"

Little Brother™'s face wrinkled.
He was getting ready to cry.

Peter looked toward the kitchen and let go.
"Don't cry," he said.
"Look, I'm building another one!
Watch me build it!"


Little Brother™ watched.
Then he knocked the tower down.


Peter had an idea.


When Mommy came into the living room again, Peter had built a tower that was taller than he was, the best tower he had ever made.
"Look!"
he said.

What kind of toy is Little Brother'M? What does the mean?
What do you think 'babbling' means? What happened when Peter hugged Little Brother"'?
How did Peter's mother stop Little from crying? What do you thiok 'wrinkled up' means? What does the last lioe make you think?What funny things did Little Brother do at first?
What do you think 'grabbed hold of' means? What do you think Peter's idea was? Why didn't Peter's mother even look at the tower? 1 What makes Little Brother a different kind of toy? Why did Peter feel annoyed with his mother? What do you think is going to happen next?
