Earth Day turns 40 years old on April 22, 20 I0. Some people clean up litter in their communities. ( It makes Earth turn to clean Earth.) In the world today, industry is advanced & developed, more and more. The world's very large population, with the environmental pollution, are serious concerns. There were a series of natural disasters this year. On January 12 a large earthquake hit Haiti. It measured 7.0-7.9 and 230,000 people died. After that, a larger quake hit Chile; it measured 8.0. This month the earthquake in Ginhai, China, had a magnitude of7.1. More than 2,000 people were killed and over 20,000 were injured. Many families suffered terrible tragedies. In China there is also severe drought in five provinces in the southeast of the country. Many people don't have drinking water, crops have dried up and severe sandstorms are on the rise. The air quality index is not good and water & air pollution is serious. A volcano then erupted in Iceland, with the resultant ash spreading in the skies over several countries in Europe. Flights were cancelled and travellers were stranded. Environmental pollution leads to many disasters in the world . Consequently, we all must pay attention to environmental protection as climate change worsens. Save our earth! Care for our people! By Ben Yi Wang
This is something to do every now and then: Open your eyes. What I mean is, there are paths that you take every day. paths that become habit. You might even slip into "automatic", as many people do while driving to work or walking to the bus/subway ... when you get where you are going and realise you don't remember the trip. Try opening your eyes and take in the scenes around you. Look for little details you might not notice; Look at the people; Watch for textures; Heighten your senses This is a great way to keep your mind young and agile and stay in the present. Enjoy your day, your night even make a game out of it!
Why did the English build them like that? Because the first rail lines were built by the same people who built the pre-railroad tramways; that's the gauge they used. Why did 'they' use that gauge then? Because the people who built the tramways used the same jigs and tools that they used for building wagons, which used that wheel spacing. Why did the wagons have that particular odd wheel spacing? Well, if they tried to use any other spacing, the wagon wheels wou ld break on some of the old, long distance roads in England, because that's the spaeing of the wheel ruts. So who built/hose old ruued roads? Imperial Rome built the first long distance roads in Europe (and Eng----===....:.....--=~--+-----~-'- land ) for their legions. The roads have been used ever since. And the ruts in the roads? Roman war chariots formed The US standard railroad gauge (distance between the the initial ruts. which everyone else had to match for fear of destroying their wagon wheels. Since the charirails) is 4 feet, 8.5 inches. That's an exceedingly odd ots were made for Imperial Rome, they were all alike number. Why was that gauge used? Because that's the way they in the matter of wheel spacing. Therefore the United States standard railroad gauge of 4 feet, 8.5 inches is built them in England , and English expatriates built derived from the original specifications for an Imperial the US railroads. Roman war chariot. Bureaucracies live forever. --7
