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.

Cycling or even walking in city areas can be a little dangerous, thanks to the fact that one is sharing the road with vehicles that are increasingly getting larger and heavier. A recent study proves that of the 1.27million people that die in road traffic crashes each year, about half are walkers, motorcyclists and cyclists. Now there may be a solution that could provide at least some help to protect this helpless group—an airbag!

    If you are worried that this safety measure will involve you taking around a heavy package or worse still, wrapping yourself inside an ugly plastic bag, the bag is fitted not on the human, but on the outside of the vehicle. And, while there are several versions of the idea in the works, the one most recently unveiled by Dutch car company TNO, seems to be the most advanced and ready to go into production.

    In the works since 2011, the airbag covers only the lower part of the windshield. This will provide the much needed buffer(缓冲)between the person's head and the pane of glass he/she would otherwise meet.

The chain of events leading to an airbag cause are quite simple—A camera fitted beneath the rear-view mirror monitors the vehicle's closeness to a walker or cyclist. Any contact with either one of them sets off the sensors in the car's bumper and quickly blows up the airbag. In addition to that the sensors also set off the car's automatic brake, reducing the chances if an even worse injury.

    In tests conducted using a model, the success of not getting injured after being hit by a car travelling at about 40km/h was about 50-50! While not perfect, it will still result in reducing the number of deaths by a huge amount.

    With TNO ready to license its technology to car makers and many more companies trying to develop similar concepts, we would not be surprised if outer airbags become a standard feature in every car pretty soon.

    E-mail has been widely used since its invention for its convenience, efficiency, and high speed. However, it is wise to remember how easily this wonderful technology can be misused, sometimes unintentionally, but can result in serious consequences.

    Now let's look at the case of the Illinois man who left the snow-filled streets of Chicago for a vacation in Florida. His wife was on a business trip and was planning to meet him there the next day. When he reached his hotel , he decided to send his wife a quick E-mail. Unable to find the note with his wife's E-mail address, he did his best to type from his memory. Unfortunately, he missed one letter and his E-mail was directed to an elderly lady whose husband had passed away (去世) only the day before. When the sad widow checked her E-mail, she took one look at the screen, let out a sharp cry, and fell to the floor in a dead faint (昏迷 ). At the sound , her family rushed into the room and saw this note on the screen:

    MY DEAREST WIFE： JUST GOT CHECKED IN. EVERYTHING PREPARED FOR YOUR ARRIVAL TOMORROW.

    P.S. SURE IS HOT DOWN HERE

    Many animals recognize their food because they see it.So do humans.When you see an apple or a piece of chocolate you know that these are things you can eat.You can also use other senses when you choose your food.You may like it because if smells good or because it tastes good.You may dislike sonic types of food because they do not look,smell or taste very nice.Different animals use different senses to find and choose their food.A few animals depend on only one or their senses,while most animals use more than one sense.

    Although there are many different types of food,some animals spend their lives eating only one type.The giant panda eats only one particular type of bamboo.Other animals eat only one type of food even when given the choice. A kind of white butterfly will stay on the leaves of a cabbage,even though there are plenty of other vegetables in the garden.However,most animals have a more varied diet.The bear eats fruits and fish.The fox eats small animals,birds and fruits.The diet of these animals will be different depending on the season.

    Humans have a very varied（广泛的）diet.We often eat food because we like it and not because it is good for us. In countries such as France and Britain,people eat foods with too much sugar.This makes them overweight,which is bad for their health.Eating too much red meat and animal products,such as butter,can also be bad for the health. Choosing the right food,therefore,has become an area of study in modern life.

    One of the greatest gifts one generation can give to other generations is the wisdom it has gained from experience. This idea has inspired the award-winning photographer Andrew Zuckerman. He interviewed and took photos of fifty oversixty-fiveyearsold all over the world. His project explores various aspects of their lives. The photos and interviews are now available on our website.

    Let us now have a culture of peace.——Federico Mayor Zaragoza, Spain Federico Mayor Zaragoza obtained a doctorate in pharmacy (药学) from the Complutense University of Madrid in 1958. After many years spent in politics, he became Director General of UNESCO in 1987. In 1999, he created the Foundation for a Culture of Peace, of which he is now the president. In addition to many scientific publications, he has published four collections of poems and several books of essays.

    Writing is a discovery.——Nadine Gordimer, South AfricaDue to a weak heart, Nadine Gordimer attended school and university briefly. She read widely and began writing at an early age. She published her first short story at the age of fifteen, and has completed a large number of works, which have been translated into forty languages. In 1991, Gordimer won the Nobel Prize for Literature.

    Jazz is about the only form of art today.——Dave Brubeck, USADave Brubeck studied music at the University of the Pacific and graduated in 1942. After World War Ⅱ he was encouraged to play jazz. In 1951, he recorded his first album(专辑). Brubeck's 1959 album has become a jazz standard. He received a Grammy Lifetime Achievement Award in 1996.For more figures CLICK HERE.

    The arts, especially music, should be part of every school's lessons at every grade level. Students would be much smarter if they had some musical experience. They could improve their classroom skills, like paying attention and following directions. People develop all these skills when they learn music. Making music also lets children use their imagination. It provides students with a chance to try out their own ideas.

    Music not only makes children better students, but also gives them something positive to do. In a music program, children can be part of a band instead of joining a gang (团伙). Parents can enjoy listening to their children's music instead of seeing them glued to a computer or TV screen. In a school band, students get to be part of a team. They can get along well with old friends and make new friends through music.

    Music builds self-confidence, too. It gives children a sense of achievement and success. Making music is something for them to be proud of, and it lets kids practice performing in front of an audience. Music gives children an opportunity for self-expression, and that helps develop their self-confidence.

    Once again, music is important because it can make children better students, give them something positive to do, and build their character. That is why music should be offered in every single grade in every school.
