15．The friendship between humans and dogs possibly began 14000 years ago．Here are four examples of"a dog's life"in the human world today．

Treated like a queen

Tiffy is one of these dogs．Her owner，Nancy Jane Loewy，treats her like a queen．She patiently prepares Tiffy's meals of meat，fish，chicken and different kinds of fresh vegetables．Tiffy also eats yoghurt and biscuits after dinner．Loewy's husband has a very good job and her two sons are away at university，so she has the time and money to treat Titty very well，and she truly enjoys doing it．"I want to give her the healthiest，most wonderful life as long as possible，"she says．

Food sniffer dogs （嗅探犬）

Food sniffer dogs work at international airports in the United States．Their job is to smell and find illegal （不合法的）fruits，vegetables and other foods in bags and mail．These foods sometimes bring insects and diseases which could be dangerous for plants and animals．The dog calmly sits down next to anything that smells suspicious （可疑的）．The dog's human partner then checks for illegal foods．Sniffer dogs are friendly and cute，so they don't scare people as they sniff through the crowds．More importantly these dogs have an astonishing nose for food．They can find food in bags 84% of the time．

Animal carers

Jessic is a whippet （小靈狗）that visits very sick children in hospital．She shows them her love and when they feel down，Jessie makes them happy．Jessie helps patients to stay strong during their time in hospital．

There are many different kinds of animals that help people．We train"service dogs"to help people with physical disabilities．The best known service dogs are guides for the blind．But they can also learn to _______，turn lights on and off，pick up objects from the floor and even pull wheelchairs．

16．Many of you have heard a Cinderella （灰姑娘） story，but you may not know that there are over a hundred different ways to tell the Cinderella story．When writers tell the same story in a different way，it is called their"version"of the story．The story of Cinderella has many different versions．Let's read two of them and find out how they are different．

The version that most people know is the oldest one written in 1697by Charles Perrault from France．This is the version where the birds help make Cinderellas's dress and the mice turn into carriage men （馬車夫） and help Cinderella go to the dance in a pumpkin （南瓜） carriage．In this version，many of the animals are Cinderella's friends．They help her meet the Prince．Cinderella marries the Prince and they live happily together ever after．

In another version of this story written in the 1850s by Jacob and Wilhelm Grimm from Germany，the birds help Cinderella in the whole story．Cinderella's father gives her a little tree when he comes back from a party．She plants the little tree and her tears water it until it grows into a tall tree．

The birds now live in the tree and they give Cinderella a dress of gold and shoes of gold．Cinderella goes to the party to meet and dance with the Prince．Later，he finds Cinderella at home doing work for her stepmother （繼母）．Cinderella marries the Prince and they live happily ever after．
