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.

    If the crust (外壳) of the earth were not pretty solid (坚固的), it would be shaking about and moving up and down frequently. However, there are places in the rocks of the earth's crust where it isn't strongly held together—where faults exist. Along the faults, one rock might push against another with great force. The energy is changed to vibration in the rocks, so they begin to shake and we have an earthquake!

    The most famous one in North America was the San Francisco earthquake of 1906. Seven hundred people died and property (财产) damage amounted to about $425,000,000.The greatest destruction came from the fires that followed the quake.

    One of the most famous earthquakes in Europe took place in Lisbon, Portugal, in 1755. The city was destroyed and at least thirty thousand people were killed. In 1908, in Calabria and Sicily, a quake killed about seventy­five thousand people. In 1915, in central Italy, hundreds of towns and villages were damaged and thirty thousand people were killed.

    Two great earthquakes that caused great damage in Asia took place in Tokyo, Japan, and in Gansu Province in China. The Tokyo quake of 1923 killed more than one hundred thousand people and destroyed the city and the city of Yokohama, too. The Chinese quake in 1920 covered more than three hundred square miles and killed about two hundred thousand people.

    A bicycle may be seen by most people as just another vehicle (交通工具), but for many Londoners, cycling is a way of life. According to an official UK government survey in 2017, about 570,000 bike journeys are made every day in London. In fact, almost half of the vehicles that pass over London Bridge each day are bikes.

    London introduced a public bike-sharing system in 2010. “There can be no doubt that our trusty bicycles have changed the way people get around our great city,” Johnson told the Guardian in 2015.

    In London, bikes are used for more than just taking short trips to and from the subway. No matter where you want to go in the city, taking a bike is usually the quickest and easiest choice.

    And it's not just shared bikes that the government is encouraging people to ride. In many companies across the UK, the UK government's Cycle to Work scheme (骑行倡议) allows employees to buy a brand new bike without having to pay any tax (税). This means that it's common to see many people cycling to and from work, and some employers even provide workplace showers and lockers (储物柜) for their workers. More importantly, a cycle-friendly boss may let you off for being late if you rode a bike to work.

    Not only is it great for the environment and our body, cycling is also good for the mind. According to National Geographic Magazine, “Bike riding can improve people's happiness.”

    A growing number of Chinese tourists are helping to save a dying town, after a like-known tourist attraction was featured on a number of Chinese travel blogs.

    The residents of Sea Lake, a town of just 600 people, barely see travelers stop at their gas station while driving by, but the sudden influx of Chinese tourists is helping keep the town's economy alive.

    The tourists come to see Lake Tyrrel—a shallow, salt crusted and often dry lake just out of town. According to a local teacher, Rachel Pearce, the extremely beautiful nightscape combined with the mysterious appearance of stars reflected on the salt lake gives people the impression of walking among the stars. Besides, the town is so far away that no light pollution ruins the particularly attractive views, and as it is situated in a barren(寸草不生的), dry part of the country, there are rarely any clouds to spoil the night sky.

    The attraction's growing sought-after status has resulted in the town's motel rooms being full almost every night, and while local farmers are suffering in a two-year drought, tourism is keeping the town's agricultural-based economy stable.

    Despite the popularity of the town and its attraction, locals are still confused as to why their little town deserves so much attention. Sea Lake's population has fallen from around 1, 200a decade ago to 600 today. "We're still unsure why Lake Tyrrel is such a big, big tourist attraction," one local says. "It's quite a shock."
