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.

    Suppose you want to go abroad and learn about the foreign exchange in culture in different countries. Here is some information you may need.

    Have you ever wondered what wild animals do when no one is watching? Scientists have been able to record the "private" moments of wildlife with leading-edge technology. Low-cost, dependable and small modern cameras are of big help.

    Cameras placed in hard-to-reach places have taken videos of everything from small desert cats to later snow loving felines (猫科) in the northern Rocky Mountains. These cameras are important tools to learn new information on wildlife.

    Some videos help scientists see the effects of climate change. For example, the desert animal javelin and the tree-loving coatimundi have been caught on cameras north of their normal home. This could mean global warming is enlarging their living area northward.

    Researchers use cameras along with global positioning systems, or GPS. They attach GPS devices (设备) to mule deer and antelope in and around Yellowstone National Park. Then they can record their movements, or migrations (迁移) . These cameras can be left in very rural (荒野的) areas for days, weeks or even month. They can provide information on how many animals are moving over a given period of time.

    Rural video can show details about animal behavior, such as the calls made by migrating. Also some cameras record animal life and show everything from bison in Saskatchewan, Canada, to the underwater weed forest off California's Channel Islands.

    However, rural cameras have their problems too. Animals such as wolverines and bears sometimes attack them. Scientists do not know if the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way. Even with such problems, rural cameras are clearly an important scientific tool in researching wild animals.

    The English language has a lot of words which can be used in many different ways and in many different expressions.

    One such example is the word matter. In fact, matter can mean just about anything. It could be one of the most useful words in the English language.

    Let's get to the heart of the matter—a matter of principle (原则).

    If someone says that you owe (欠) him $50, but you don't, a friend might say, "Well, you could pay him the $50. It's not that much money. Then you won't have to hear him say it anymore." But if you do not owe him the money, do not pay him the money. It's a matter of principle.

    There is another way to use the word matter. But be careful with your choice of words.

    If you ask someone, "What's the matter?" it shows you are worried about the other person. But saying, "What's the matter with you?" has a completely different meaning. And it usually sounds rude (粗鲁的). In fact, when you say, "What's the matter with you?" you are suggesting that the person did something wrong or stupid.

    Another expression that could sound rude is to say, "It doesn't matter to me." Here, it depends on the context, and how you say it.

    Let's say you tell someone that a friend just got a big raise at work. That person answers with, "It doesn't matter to me." Here, it means he or she does not care. And it sounds rude.

    But saying, "Oh, you pick where we eat dinner. It doesn't matter to me." does not sound rude. In this situation, "it doesn't matter" shows you are easy-going (随和的).

    No matter how you look at it and what you say, matter is a very useful word. And it's only a matter of time before you will become an expert on the use of matter.

    Being deaf in a hearing world can lead to painful feelings of isolation (孤独).

    Waitress Kelsey recently shared an experience on a social media sharing site that quickly zoomed (陡直上升) to the top of the" front page of the Internet". In her brief post, Kelsey explained that she waits tables at a bar during the evenings, and one night she noticed a deaf man sitting alone in her section (区域).

    When Kelsey isn't working at the bar she makes a good hourly pay doing sign language interpretation (翻译), so she sensed an opportunity to use her skill to make this customer feel a little less alone in the world. She approached his table and began chatting with him in sign language.

    When the table next to his noticed their silent conversation they asked Kelsey how long she'd been signing. They had a brief conversation about her goal of becoming certified (合格的) to interpret sign language in a medical or mental health setting. She didn't think much about the whole exchange until the customers had left the restaurant and she was tidying up the tables. There, on the table of the customers who'd seen her American sign language conversation with the deaf man, was a handwritten note on the receipt.

    "Thank you for what you do; it absolutely matters!" the note said. "Good luck with finishing your degree!" Not only that, but they'd left her a $100 tip.

    Kelsey was moved by the kind note, especially because she wasn't doing anything out of the ordinary. To her, she was just conversing with someone in a language that only they understood. Yet to the deaf man and the people seated next to him she'd bridged a gap and helped someone who probably feels lonely a lot of the time.

    Kelsey shared the note on the Internet to spread more love and light in the world.
