Using too much water or throwing rubbish into our rivers are clear ways that humans can put our water supply in danger, but we also affect our water supply in less obvious ways. You may wonder how paving(铺砌) a road can lead to less useable fresh water. A major part of the water we use every day is groundwater. Groundwater does not come from lakes or rivers. It comes from underground. The more roads and parking lots we pave, the less water can flow into the ground to become groundwater.

Human activity is not responsible for all water shortages(缺乏). Drier climates are of course more likely to have droughts(干旱) than areas with more rainfall, but in any case, good management can help to make sure there is enough water to meet our basic needs .

Thinking ab out the way we use water every day can make a big difference,  too. In the United States, a family of four can use 1.5 tons of water a day! This shows how much we depend on water to live, but there’s a lot we can do to lower the number.

You can take steps to save water in your home. To start with, use the same glass for your drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks(滴水) in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

Although English is not as old as Chinese, it is spoken by many people around the world every day. English speakers are always creating new words, and we are often ab le to know where most words come from.

Sometimes, however, no one may really know where a word comes from. Did you ever think about why hamburgers(汉堡包) are called hamburgers, especially when they are not made with ham(火腿)? About a hundred years ago, some men went to America from Europe. They came from a big city in Germany called Hamburg. They did not speak good English, but they ate good food. When some Americans saw them eating round pieces o f beef, they asked the Germans what it was. The Germans did not understand the question and answered, “We come from Hamburg.” One of the se Americans owned a restaurant, and had an idea. He cooked some round pieces of beef like those which the men from Hamburg ate. Then he put each between two pieces of bread and started selling them. Such bread came to be called “hamburgers”. Today “hamburgers” are sold in many countries around the world.

Whether this story is true or not, it certainly is interesting. Knowing why any word has a certain meaning is interesting. too. This reason, for most English words, can be found in any large English dictionary.
