Clean water is not only important for people to produce food，but necessary for our life. However，many people in Asia and Africa don’t have enough clean water to use. The World Health Organization reports that almost 4,000 children die each day of dirty water or lack (缺乏) of water. 

Farmers use 70—85% of the world fresh water to produce food. People usually don’t pay much attention to how much water industry(工业)uses，but you may be surprised to know that industry uses 59% of the water in developed countries.

  Home use takes up(占据)only 8% in the world. But as cities grow，more water will be used. The local government has to try to make people use less water.     

  In 60% of European cities，people are saving water by using less. They even keep waste water for other use.

  In Australia，the government has encouraged people to collect rainwater and recycle water from showers for a second use.

  The US Environmental Protection Agency has made a water saving program to encourage families and businesses to check their water use and save more water. Scientists and the UN are looking for good water management as the key to solving the problem. We can all work together to protect our fresh water in our daily life.

 Do you know how to use a mobile phone without being rude to the people around you?

Talking during a performance irritates (激怒) people. If you are expecting an emergency call, sit near the exit doors and set your phone to vibrate (振动). When your mobile phone vibrates, you can leave quietly and let the others enjoy the performance.

Think twice before using mobile phones in elevators, museums, churches or other indoor public places — especially enclosed spaces. Would you want to listen to someone’s conversation in these places? Worse yet, how would you feel if a mobile phone rang suddenly during a funeral? It happens more often than you think. Avoid these embarrassing situations by making sure your mobile phone is switched off.

When eating at a restaurant with friends, don’t place your mobile phone on the table. This conveys the message that your phone calls are more important than those around you.

Mobile phones have sensitive microphones that allow you to speak at the volume you would on a regular phone. This enables you to speak quietly so that others won’t hear the details of your conversation. If you are calling in a noisy area, use your hand to direct your voice into the microphone.

A strong vocabulary can be a valuable asset, both in college and later in your career. Considerable research evidence suggests the students who are most successful in school are those with the largest vocabularies. Other research ties job advancement to vocabulary level .In one study, successful business executives were found to have the highest vocabulary of any occupational group.

Your vocabulary is also an important personal characteristic upon which people form their first, but lasting, impression of you. Your vocabulary reveals a lot about you and is particularly important in job interviews, oral class presentations, discussion group classes, and papers and exams that you write.

  How would you rate your vocabulary? Many students answer either “good” or “terrible”, but vocabulary knowledge is not an either-or, two-choice situation. Try the following quiz, which will help you realize that vocabulary ability is much more than “Either I know the word or I don’ t.” Do not be concerned with how you score on the quiz; its purpose is to make a point, not to measure your vocabulary level.
