Recently I had my first ride on a long-distance train. And what a ride! A friend and I travelled on the famous Ghan train. We got on in
5、 Sydney and we got off in Alice Springs, right in the middle of Australia, more than four thousand kilometres away. We spent two days and nights on the train.The train was wonderful and the food was great. We ate great meals cooked by experts! For the first few hundred kilometres of the journey, the
6、 scenery was very colourful. There were fields and the soil was dark red. After that, it was desert. The sun shone, there was no wind and there were no clouds in the sky. Suddenly, it looked like a place from another time. We saw abandoned farms which were built more than a hundred years ago. The tr
7、ain was comfortable and the people were nice. During the day, I sat and looked out of the window, and sometimes talked to other passengers. I read books and listened to my Chinese cassettes (Im studying Chinese at school). One night, at about midnight, I watched the night sky for about an hour. The
8、stars shone like diamonds.Why is the train called the Ghan? A long time ago, Australians needed a way to travel to the middle of the country. They tried riding horses, but the horses didnt like the hot weather and sand. A hundred and fifty years ago, they brought some camels from Afghanistan. Ghan i
9、s short for Afghanistan. Camels were much better than horses for travelling a long distance. For many years, trained camels carried food and other supplies, and returned with wool and other products.The Afghans and their camels did this until the 1920s. Then the government built a new railway line,
10、so they didnt need the camels any more. In 1925, they passed a law which allowed people to shoot the animals if they were a problem. In 1935, the police in a town shot 153 camels in one day.Module4ASocialSurveyMyNeighbourhoodlivelycityItgreatseeagain,John.you!sixyearssincewelastsaweachother,know.vis

14、ld without metals. Different metals have different uses, for example, steel is used in cars, and iron is used in electrical equipment. When we use metals, it is important to know how they react with different substances, for example, water and oxygen. The reaction of metals with these substances can
15、 be put in order. Here is a table with the metals that react most at the top, and the metals that react least at the bottom.Passage B A Simple Scientific ExperimentBelow is a description of a simple scientific experiment. It shows us how iron reacts with air and with water.Aim: To find out if iron r

17、e.(3) Leave the tube for one week.ResultAfter one week, the nails have not rusted.ConclusionIron does not rust in dry air.Iron in air-free water(1) Half-fill a test tube with water.(2) Boil the water for three minutes. (This makes sure there is no air in the water.)(3) Put two or three clean nails i
18、n the water.(4) Add some oil to the water. This will keep air out of the water.(5) Leave the tube of one week.The nails do not rust in the tube with air-free water.Iron rusts in ordinary water.My feelings about science have really changed. I never used to enjoy science,but last year I changed school
19、s,and the science teachers at my new school are excellent. The science facilities are very good,with laboratories that have all the latest equipment. Our chemistry teacher,Mr Longford,takes us to public science lectures about four times a term,and these are always very interesting, as the lecturers are people who have made real discoveries in their area of science. The fact is,Canada has many first-class scientists. In the last twenty years,seven Canadian scientists have won the Nobel Prize!The Nobel Prize is the highest scientific prize there is,so we
