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 usable 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.

Hunan activity is not responsible for all water shortages(短缺). 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 about 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 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 you home. To start with, use the same glass for drinking water all day. Wash it only once a day. Run your dishwasher only when it is full. Help your parents fix any leaks in your home. You can even help to keep our water supply clean by recycling batteries instead of throwing them away.

Breakfast is the most important meal of the day. It is also the most neglect (忽视). Common reasons for not eating breakfast include having no time, not feeling hungry, traditional dislike and dieting.
Breakfast simply means “break the fast’’. Your body spends at least 6 to 12 hours each night in a fasting state. In the morning your body needs energy for the day’s work ahead. 
A good breakfast should provide 1/3 of your total calorie(卡路里)needs for the day. On average, we eat 400 less calories for breakfast than for dinner. If breakfast doesn’t appeal (吸引) to you in the morning, try eating a lighter dinner earlier in the evening or save half of your dinner for breakfast in the morning.
If you still aren’t hungry in the morning, start with something small like juice or toast or have a nutritious (有营养的) mid-morning snack (小吃) later when you are hungry.
So, you say you are on a diet. Some people fear that eating breakfast will make them hungrier during the day and they will eat more. It is true that eating breakfast is likely to make you feel hungry throughout the day. That is because your body is working correctly. Although you may feel as if you are eating more all day long, in reality you are probably not.
Not eating breakfast can also cause you overeat, since a fall in blood sugar often makes you feel very hungry later. To make matters worse, since your body is in a slow state, it will not be able to burn those extra calories very efficiently (有效). If you feed your body healthy snacks and meals throughout the day, you are less likely to become hungry and stuff (填饱) yourself as soon as you begin to eat.
Since breakfast is the first and most important meal of the day, choosing the right food is important. The best breakfast foods are fruits, juice, lean meat and grain products such as bread, rice, noodles and cereals.

Learners of English, especially self-taught learners may have trouble in understanding speeches by native speakers. The following ways might help improve their listening ability.
First of all, do things step by step. It is not good to listen to something beyond your level. Better choose a suitable course and start with the first book. Go on to the second book only after you are sure you understand the first one.
Secondly, stick to one course of study. Don’t change books often. Never let your attention be attracted by another course just because it seems to be more “fashionable”. 
Thirdly, listen to the English news program over the radio from time to time.  Better go through the news stories in the Chinese-language newspaper first. That will make it easy for you to understand the English news on the radio.
Fourthly, if you have time, listen to some interesting stories in “Special English from the V.O.A. or other listening materials of the same level as that of your textbook”.
