It was 3:21 a.m. when nine-year-old Glenn Kreamer awoke to the smell of burning. Except for the cracking(爆烈声) of flames somewhere below there was not a sound in the two-storey house at Baldwin Long Island.

With his father away on night duty at a local factory, Glenn was worried about the safety of his mother, his sister Karen, 14 and his 12-year-old brother Todd. He ran downstairs through the smoke-filled house to push and pull at Karen and Todd until they sat up. Then he helped each one through the house to the safety of the garden. There, his sister and brother, taking short and quick breaths and coughing, fell down onto the lawn.

The nine-year-old boy raced back into the house and upstairs to his mother's room. He found it impossible to wake her up. Mrs. Kreamer, a victim of the smoke, was unconscious(昏厥的), and there was nobody to help Glenn carry her to the garden. But the boy remained calm and, as a fireman said later, "acted with all the self-control of a trained adult."

On the bedroom telephone, luckily still working, Glenn called his father and, leaving Mr. Kreamer to telephone the fire brigade and ambulance service, got on with the task of saving his mother.

First he filled a bucket with water from the bathroom and threw water over his mother and her bed. Then, with a wet cloth around his head he went back to the garden.

He could hear the fire engine coming up, but how would the firemen find his mother in the smoke-filled house where flames had almost swallowed up the ground floor?

Grasping firmly a ball of string(线) from the garage, Glenn raced back into the house and dashed upstairs to his mother's room. Tying one end of the string to her hand, he ran back, laying out the string as he went, through the hall and back out into the garden.

Minutes later he was telling fire chief John Coughlan, "The string will lead you to mother." Mrs. Kreamer was carried to safety as the flames were breaking through her bedroom floor.

B. He was worried about his mother's safety.

D. He went to see if his father had come back from work.

2.Who called the fire brigade and ambulance service?

If you find yourself constantly checking your cell phone, you may have a problem with

overuse of cell phone. 1. Here are four tips on how to create better phone habits.

1. Put your phone away an hour before you go to sleep. Staring at a screen right before

you try to go to sleep is going to make it more difficult to fall asleep. 2. Don’t try to

sleep with it right next to your head because you will spend more time focused on who might

be texting you than sleeping.

2. Carry your phone in your bag or pocket. When you take your phone with you, don’t

carry it in your hand. 3.This is especially important when you drive. Make sure your

phone is hidden away when you drive so you are not tempted to look at it and text.

3. 4. Think of the best times of the day for you to not be on your phone texting

and make it a “no phone time”. Turn your phone completely off and put it away somewhere

where you can’t get to it for a few hours. Forcing yourself to do this daily will help train your

brain to not get anxious when you are not on your phone.

4. Pretend like your cell phone is a home phone. 5. Try pretending like your cell

phone is a landline phone. Place it in one spot in your house and always leave it there and

only use it there, instead of taking it with you everywhere you go.

A. An hour before you go to sleep, text anyone you are talking to that you are going to sleep.

B. Cell phones are an annoying invention.

C. Have set times where you are away from your phone.

D. Turn off your cell phone before you leave your home.

E. Probably one of the major reasons you are addicted to (上瘾)texting is because you can carry your phone with you anywhere.

F. It can lead to reduced quality of personal relationships and lack of productivity in daily life.

G. Put your phone somewhere where you can’t see it.

Artificial intelligence,or AI,has been applied in a wide range of fields to perform specific tasks,including education,finance,heavy industry,transportation,and so on.

Education

There are a number of companies that create robots to teach subjects to children ranging from biology to computer science,though such tools have not become widespread yet.Advancements in natural language processing, combined with machine learning,have also enabled automatic grading of assignments.AI has also led to an explosion in popularity of MOOCs,or Massive Open Online Courses,which allows students from around the world to take classes online.

Finance

Use of AI in banking can be tracked back to 1987.Banks use artificial intelligence systems to organize operations,maintain book-keeping,invest in stocks,and manage properties.Also,systems are being developed,like Arria,to translate complex data into simple and personable language.There are also wallets,like Wallet AI,which monitor an individual's spending habits and provides ways to improve them.

Heavy industry

Toys and games

Companies like Mattel have been creating AI-enabled toys for kids as young as age three.Using proprietary AI engines and speech recognition tools,they are able to understand conversations,give intelligent responses and learn quickly.AI has also been applied to video games,for example video game bots,which are designed to stand in as opponents where humans aren't available or desired.
