The Australian continent is a land like no other. Its animals, plants and landscapes have evolved   over one thousand years, and there are about a million different natural species  in Australia. More than 80 per cent of the country's plants and animals are unique to prefix = st1 /Australia, along with most of the fish and almost half the birds. Australia has more than 140 species of marsupials  ,including koalas, wombats and the Tasmanian devil, now found only in the Australian wilderness. More than 750 species of birds have been recorded in Australia, 350 of which are found nowhere else in the world. Among them are the kookaburra, the rainbow lorikeet and fairy penguins. There are also 55 differernt species of macropods--the kangaroo family--native toAustralia. They vary greatly in size and weight, ranging from half a kilogram to 90 kilograms. The country has been making every effort to protect its natural heritage. Despite the large size of the continent, the majority of Australians live on the coast and in major cities--around 75 per cent of Australia's population lives in city areas. Australia is the driest continent on earth. Its center has one of the lowest rainfalls in the world and about three-quarters of the land is dry. These dry areas extend from the large central deserts to the western coast. Soils in these areas are very poor compared to other deserts. This has given Australians a great challenge.They have to make the best use of the variety of regions to meet the competing demands of agriculture, economy and conservation. Most of Australians live_. A) in the middle of the country B) in the countryside C) in the west of the country D) in the coastal cities

Just be happy. Sounds too simplistic, doesn't it? But, in reality, we can have much more happiness if we choose to consider things from a positive point of view. Everyone experiences the ups and downs of life, however, we can make a decision to take advantage of the negative or practice what the old saying says to do:" _ !"      It really boils down to your attitude and you have the ability to work your attitude into any shape you like.

Each day has enough of its own. *Don't allow trouble to bury you in its gray depth of sorrow. *Don't give in to negative thinking. *Be positive even when others are not. *Refuse to give up on anything worth having or doing. *Do something you enjoy each day, even if it's just a walk in your neighborhood. * Whistle  as you go though the day. *Work at being happy because it's worth it. You're human, like everyone else, and from time to time you need a little pick-me-up in your decision to be happy. When you reach that stage, find someone else who has decided to be happy. Join forces with him and march forward in your decision to be a happy person. Simply speaking, a happy person is not a person in a certain set of circumstances  but rather a person with a certain set of attitudes. Choose today to just be happy----as much as it depends on you! Which of the following does NOT help maintain  your good state of mind? A) Think in advance about future troubles. B) Greet others with a cheerful smile. C) Stay positive all the way through. D) Try to enjoy every single moment.

Ears are for hearing -- everyone knows that. But for a creature called the Cuvier's beaked whale, hearing starts in the throat, a new study found.  The observation might help explain how all whales hear. The work might also help scientists understand how animals are affected by underwater sonar  . This sonar, used by some ships, sends out sound waves to locate underwater objects.  The Cuvier's beaked whale is a so-called toothed whale. Toothed whales dive deep into the ocean in search of food. As the whales hunt, they produce sounds that reach objects and then return to the whales. This allows the animals to "see" the shape, size, and location of objects, even when they're 1,000 meters under the sea, where it is totally dark.  To better understand how the whale hears, researchers from San Diego State University in California took X-rays of two Cuvier's beaked whales. The whales had died and washed up on the beach.  Ted Cranford and his colleagues used the images to make a computer model of a Cuvier's beaked whale's head. Then, they modeled the process of sound traveling through the head.  The researchers knew that some sounds get to the ears of a toothed whale through a structure called "the window for sound". Found on the lower jaw, this structure is very thin on the outside and has a large pad   of fat on the inside.  When the researchers used their computer model to work out how sound waves travel in the whale's head, they were surprised to find that sounds coming from right in front of the whale actually travel under the animal's jaw. From there, sound waves move through the throat, into a hole in the back of the jaw, and finally to the pad of fat near the animal's ears.  Cranford guesses that other types of whales may hear through their throats. Further testing is needed to be sure. Eventually, the insight into how whales hear might explain whether sonar testing by military ships is causing the animals to wind up on beaches. Researchers took X-rays of two Cuvier's beaked whales in order to   _  . A) find out why they had died and washed up on the beach B) make a computer model of a Cuvier's beaked whale's head C) make sure that sound travels through the head D) know more about the way the whale hears
