Australia is the smallest continent in the world. It is a little smaller than China. It is on the Southern Hemisphere of the earth. Australia is big, but its population is small. The population of Australia is nearly as large as that of Shanghai.

    Enough laws have been made to fight against pollution. The cities in Australia have little air or water pollution. The sky is blue and the water is clean. You can clearly see fish in the rivers. Plants grow very well.

    Last month we visited Perth, the biggest city in Western Australia, and went to a wild flower exhibition. There we saw large numbers of wild flowers on show, most of which we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. Every year in spring Perth has a wild flower exhibition. After visiting Perth, we spent a day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves very much. When we heard bells ringing at the top of the hills, we looked up, but what we saw made us pick up all our things and run back to our car as quickly as we could. There were about three hundred sheep coming towards us along the path.

    Australia is famous for its sheep and kangaroos. After a short drive from any town, you will find yourself among the white sheep. Sheep, sheep, everywhere you can see sheep.

    “We are good mothers,” I said to my friend, as we sat on our comfortable beach chairs under our beach umbrella and watched our children playing in the waves.

    Out of nowhere, the children took off running. About fifty yards from us, a man—maybe in his fifties—was fishing. The children stood next to him and watched with their little mouths hanging open as he cast the fishing lines. He smiled at them. They ran back to us—all except my three-year-old daughter, Drew.

    My heart beat fast with horror. “Drew! Come here! Play with your friends!” I shouted, very aware that my speeches about not talking to strangers weren't working. It seemed that many parents heard of horrible stories about children being taken away by strangers. Responsible mothers should teach their children that the world is a dangerous place. So I felt relieved (松口气) when Drew ran towards me and took hold of a shovel (铲子). Then she looked me in the eye: “I want to be with the person.”

    Again, she approached the middle-aged man, and started digging next to him.

    Several seconds later, she returned, waving something shiny.

    “Look, Mommy! A toy fish!”

    It was, indeed, a toy fish—yellow and rubber. This must have been what he was using to attract the fish. And he'd given it to Drew. The three other children were deeply impressed, and they didn't try to hide how jealous(妒忌的)they were—clearly, they all wanted the fish.

    “My friend gave me that fish!” Drew shouted loudly. The sand in front of the umbrella turned into a preschool cage match with a yellow rubber fish flying through the air. I felt like I might cry myself.

    Unexpectedly, there he was: the man, standing right next to us with three more rubber fish in hand. He handed them to each of the children. By their faces, you would have thought he was actually the really kind big brother.

    “Thank you,” I said, realizing that there is good and kindness in strangers.

    MySpace, the social networking website, is different from other websites which only provide stories about other people. MySpace is a place that allows you to broadcast your own stories and personal information to as many people as you like. Started two years ago, it is a big source of information for and about American kids.

    Teenagers and their parents feel very different about it. Teens are rushing to join the site, not sharing their parents' worries. It signals yet another generation gap in the digital era.

    For teenagers, it is reliable network to keep in touch with their friends. They will often list their surnames, birthdays, after­school jobs, school clubs, hobbies and other personal information.

    "MySpace is an easy way to reach just about everyone. I don't have all the phone numbers of my acquaintances. But if I want to get in touch with one of them, I could just leave them a message on MySpace, "said Abby Van Wassen. She is a 16­year­old student at Woodland Hills High of Pittsburgh, Pennsylvania.

    Parents on the other hand are seriously concerned about the security problems of MySpace. "Every time we hold a parents meeting, the first question is always about MySpace, "said Kent Gates, who travels the country doing Internet safety seminars(研讨会). The National Centre for Missing and Exploited Children has received at least 288 MySpace ­ related complaints, according to Mary Beth Buchanan, a lawyer in Pittsburgh.

    "Your profile on MySpace shows all your personal information to anyone on the Web. And MySpace even lists this information by birthplace and age. It's like a free checklist for troublemakers and it endangers children, " Buchanan said.

    A bright yellow “M” tells you that it's a McDonald's restaurant; we also associate the cheerful theme tune “I'm Lovin' It” with the famous US fast food.

A brand's music has a similar effect on its customers as its logo. “It appeals directly to the heart, where consumers' decisions are really made,” wrote Marketing Week.

This is probably why companies from around the world have recently focused more on building a “sonic (声音的) identity”.

    An example is the software company Tencent QQ. Since 2014, this Chinese company has been trying to trademark (申请商标权) its “Di-Di-Di-Di-Di-Di” notification sound. The trademark was finally approved on Nov 15, which means that Tencent's “Di-Di-Di-Di-Di-Di” notification sound is now protected by law and can only be used by QQ.

    Sound and music can also help tell stories. In Game of Thrones (《权力的游戏》) there are so many characters that it is difficult to memorize them all. So, they wrote melodies (旋律) specific to each family. The result is that characters do not only look familiar, but sound familiar too.

    “I think a huge reason why sound inspires action is that, on an unconscious level, we are always listening,” Lauren Nagel, executive creative director at Pandora Media, told GeoMarketing. “You can close your eyes, but you can't shut your ears.”

    Shot in more than 40 locations in L.A., the musical La La Land is "a love letter to the city". To coincide with UK release, we asked a local writer to pick some of the film's amazing settings.

    Judge Harry Pregerson Interchange

    La La Land's opening scene is a six-minute dance that plays out in L.A.'s bad traffic. It is also where the film's leading roles, struggling actress Mia and jazz pianist Sebastian, first encounter each other—in a road anger incident. The scene is said to have been filmed over two hot days in south L.A.

    Smokehouse Restaurant, Burbank

This is the setting for the scene in which Mia discovers Sebastian's talent for the piano. The fictional Lipton's restaurant—where jazz purist Sebastian was reluctant to play Christmas music—is in reality a place long frequented by actors, producers and other show business types. It has been on this spot, across the street from the Warner Bros studio, since 1949. In the film, the outer wall of Lipton's is the You are the Star mural (壁画), which features Marilyn Monroe, Charlie Chaplin and others, which is on the corner of Hollywood Boulevard and Wicox Avenue in Hollywood in reality.

    Warner Bros Studios, Burbank

    Mia works at the studio's coffee shop, where Sebastian comes to meet her. As they wander the studio's lot, Mia points out "the window that Humphrey Bogart and Ingrid Bergman looked out in Casablanca." It's one of the film's numerous nods to movie history. Warner Brons is still a working studio, with 35 sound stages, 14 exterior sets and visitor tours.

    Cathy's Corner, Mount Hollywood Drive

    This section of the road that winds through Griffth Park is the setting of their dance play. It overlooks the San Fernando Valley and features on the film poster. Cathy's Corner is near famed Mulholland Drive, but prepare for disappointment if you're expecting a park bench and street lamps, which only exist in the movie.

    People living in the country enjoy several advantages that people living in the city cannot enjoy.

    They are in close contact (接触)with nature. They make friends with trees and stones. They breathe fresh air. They fight with strong winds. They listen to the song of birds. This contact with nature is good for health. There are many diseases that are common in the city, but are not to be found in the country. For example, near­sightedness is almost unknown to country people. Because of the absence of cars, one can walk more freely in the country than in the city. There are no rules of the road nor traffic signs to obey. People living in the country can easily get fresh vegetables, fresh fruit and fresh milk, and they get them at lower prices than in the city. Country life is economical (节俭的)in other ways, too. There are practically no temptations to waste money.

    Country people are mostly honest. They say what they mean, and make and keep promises with sincerity (诚意). They do not put on air (摆架子). They do not pretend to have those ridiculous (荒谬的)manners which are necessary in what we call polite society.
