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.

    The ability to speak more than one language certainly has its special benefits.It enables you to work in another country or interact with people whose language is different from your mother tongue.Cognitive（认知的）  psychologists have been interested in how bilingualism（双语能力）shapes the mind for almost a century.There are those who suggest that in order to speak one language,bilinguals have to suppress（抑制）the influence of the other.In the past three decades,research had argued that this unique form of language processing trains the brain in the use of abilities known as "executive（执行的）functions" such as ignoring irrelevant information or shifting attention. Bilinguals of different ages and cultural backgrounds have been shown to be faster and more accurate than their monolingual（单语的）peers when performing cognitive tasks demanding these abilities.Furthermore,it has been argued that bilingualism may lead to a delayed onset（发作）of symptoms associated with dementia（痴呆）.

    But the scientific community recently has become increasingly skeptical of the bilingual advantage.One of the main points of criticism is that differences between monolinguals and bilinguals when it comes to executive functions are not always apparent.It appears that research on bilingualism is at a turning point.We need to pursue a new approach to understand,beyond those individual examples of executive functions,how the bilingual mind works. We have attempted to address this challenge by testing whether bilinguals and monolinguals differ in terms of how accurately they can assess their own performances.This ability is called meta cognition and is associated with other areas where bilinguals have been shown to have an advantage.

    In our research,we presented participants with a situation in which they had to observe two circles on a screen and guess which one contained more dots.Sometimes the difference was obvious,making the decision easy,while at other times the decision was very difficult (for example,one circle contained 50 dots and the other 49).Participants were then asked to determine how confident they were in their decision on a scale from less to more confident than normal.

    During the course of two experiments,we found that bilinguals and monolinguals were equally likely to choose the circle containing the highest number of dots.However,monolinguals were better able than bilinguals to discriminate between when they were right and when they were wrong.In other words,bilinguals had less insight into their performance than monolinguals.This went against our initial predictions,as we expected to find a bilingual advantage in meta cognitive processing.These results indicate that bilingualism may be associated with cognitive disadvantages as well as benefits.

    Jack was born without eyes. He's very lucky with his timing. He grew up having other kittens to play and socialize with, and was used to people from the moment he was born since there are always kids hanging around the barn. He was a favorite amongst the students at the barn. However, when it came time to find the kittens homes, no one knew where Jack would end up. That's when I got an e-mail from my friend. All she asked was “Do you still want one of the kittens? There's one here with no eyes and no one can take him.” Without thinking I told her that I did want the kitten.

    When we first brought him home Jack stayed mostly in my room. He walked cautiously around, sniffing everything. After about a day he had no issues running around, jumping onto my bed and climbing on everything. He went through a time where he could climb the stairs, but couldn't get down. He would sit at the top and cry until someone came and got him. Every now and then when he gets disoriented he'll stop and cry. But we just call his name and talk to him and it isn't long before he finds his way back to us.

    Also, a few weeks after getting Jack, we got a new barn cat named Bear. I always take Jack outside at that time for some fresh air and exercise. He loves to run (at top speed!) around the back yard and gardens. Bear and Jack have become best friends. It doesn't matter that he can't see, Jack always knows when Bear is around. He'll run across the yard straight to Bear and wrap his front legs around his neck in a big hug. They chase each other around and wrestle, and when they're tired they'll lie down in the grass together.

    Jack is truly an inspiration. I've owned a lot of kittens in my life, but Jack is the happiest, most playful of them all. He doesn't feel sorry for himself. Heck, for all he knows, all cats are just like him. People who know Jack don't feel sorry for him. They cherish him for the treasure that he is. I have talked to a few people who haven't met him personally who tend to pity him, but they just don't understand. Jack doesn't need pity. I think Jean (who has Gumbo the eyeless ginger) said it best when she told me that cats don't have disabilities, they have adaptabilities.

    Often people receive a guitar, mandolin, or some other musical instrument as a birthday or Christmas gift. There's joy everywhere. The giver of the gift knows how much the receiver wants to learn this instrument and the receiver is actually holding it in his hands instead of longing for it through the shop window.

    Finding an instructor that fits into a busy work schedule is hard enough, but once you decide on a lesson plan, then you must consider the practice time, how to practice, what to practice—and let's face it...not all people learn something the same way. So in order to learn a musical instrument, how much practice time is enough and what kind of practice is right for you?

    There is no set amount of time that anyone should practice a musical instrument. When I was in programming classes, I could have studied nightly for 5 hours each night. It would have taken me years to learn the art of computer programming. Though I'm attracted by the systematic logic of it, my talent is towards another thing. However, on the other hand, if I spent an hour every couple days with a passionate hobby like playing the violin, not only would the time fly quickly...I'd also be learning at a much greater speed since the built-in passion is the motivation for advancement.

    So as much as it's important to practice, a step back is to first find the harmonious instrument that fits you as a person; as development of your personality. If you're learning the guitar because it's cool....obviously that's the modern-day mindset, however, you might not be actually linking your talent for musical satisfaction with your most creative advantages you have to offer.

    It's been my experience that every person has a certain level of musical talent. My pleasant challenge has been to assist them in this adventure and actually locate their best abilities as quickly as possible. Then and only then can we match learners with instruments and truly begin a fun and exciting walk down the road of happiness and contentment, where music, ability, personality and soul all meet. Once this piece of the mystery puzzle is in place, I've never had to work at motivating a learner to practice...

Elon Musk is a symbol of passion, hard work and success. A person may work hard in his life, but when hard work goes along with passion and a new idea, then something is created that astonishes the world. As the founder of big companies like PayPal, SpaceX and Tesla Motors, Elon Musk is a guide and inspiration for the youth around the world. 

Elon Musk was born on June 28, 1971 in Pretoria, South Africa. He was the eldest of three children. His father Errol Musk, a British-born South African, was an engineer. Musk spent his childhood in South Africa and at the age of 9, he got his first personal computer. This got Elon interested in programming and he started to learn on his own. At the age of 12, he made his first computer game, Blaster, which earned him $500 when he sold the source code to a magazine. 

When he was 17, he decided to leave home and had wanted to move to the United States after graduating from a secondary school in Pretoria. However, he was unable to move to the United States. In 1989, Elon Musk moved to Canada, where his mother's relatives lived. After obtaining Canadian citizenship, Musk went to Montreal. Due to a lack of money, he found a low-paying job. At the age of 19, he entered Queens University in Kingston, Ontario, studying there for two years. Finally, in 1992, his dream came true—he moved to the United States. 

As a teenager, Musk struggled with depression. But then he realized that the most important thing was presenting himself with the right questions. The day he started doing this, everything started to get easier. 

Musk thought that a human being had to expand the limits of his consciousness—to ask the right questions and get answers to them; thus he asked the best question of all: what will have the greatest impact on the future of humans? Musk found that these things were the Internet and space exploration. 

The life of Elon Musk is inspiring. He found success on the Internet, without much formal learning. By reading books and using his willpower and dedication, he reached a level of knowledge that is difficult to imagine. He did not give up until he achieved his dreams. Elon Musk truly stands out among other billionaires because of his leadership abilities, positive attitude, ability to know when to take risks, and belief in futuristic technologies.
