14．Attitude is a way that we think and feel about someone，or a way that we behave．We all have great potential and we all desire good results from our efforts．Each of us has the ability to put our unique human potential into action and to acquire a desired result．But the one thing that determines the level of our potential，and that predicts the quality of the result we receive is our attitude．
With a positive attitude we experience pleasant and happy feelings．This brings brightness to the eyes，more energy，and happiness．Our whole being broadcasts good will and happiness．We believe we will have a bright future．Even our health is affected in a beneficial way．
A negative attitude creates unhappy feelings，moods and behavior．When the mind is negative，poisons are released into the blood，which cause more unhappiness and negativity．This is the way to failure，frustration and disappointment．
People can affect our attitude by teaching us poor thinking habits or unintentionally misinforming us or providing us with negative sources of influence，but no one can control our attitude unless we voluntarily give in to that control．No one else"makes us angry．"We make ourselves angry when we give in to control of our attitude．What someone else may have done is irrelevant．We choose，not they．They merely put our attitude to a test．If we select a changeable attitude by becoming unfriendly，angry，jealous or suspicious，then we have failed the test．If we condemn ourselves by believing that we are unworthy，then again，we have failed the test．
If we care at all about ourselves，then we must accept full responsibility for our own feelings．We must learn to guard against those feelings that have the possibility to lead our attitude down the wrong path and to strengthen those feelings that can lead us confidently into a better future．
If we want to receive the rewards the future holds in trust for us，then we must exercise the most important choice given to us as members of the human race by maintaining （维持） full control over our attitude．
Having the right attitude is one of the basics that success requires．The combination of a sound personal philosophy and a positive attitude about ourselves and the world around us gives us an inner strength and a firm resolve （决心） that influences all the other areas of our existence．

13．Acid rain is a very serious environmental threat faced by our planet today．Millions of people get affected by it on a daily basis．This problem is more serious in the northern hemisphere （半球） where there's a huge growth in the number of industries．Winds absorb more and more quantities of harmful gases produced by various kinds of industries．Acid rain occurs when high levels of sulfur dioxide and nitrogen dioxide enter in the atmosphere and start chemical transformation．These harmful gases are absorbed by water droplets in the clouds and they fall on the earth during rains．They can damage the natural soil by increasing the acidity levels and pollute rivers and lakes．Dead and weakened trees are a very common sign of acid rain，while in cities worn off or scarred buildings are also a result of acid rain．
Acid rain is actually a broad term which is used to describe different types of acid that fall from the atmosphere on earth．It's mainly divided into wet and dry．Parts of the world which experience wet weather have acid rain，acid snow and fog．Other parts which experience dry weather for most of the year experience acid gas and acid dust．
One of the main causes of acid rain is a sudden drop in the pH levels of water and that happens because of absorption of harmful gases by the atmosphere．The best way to bring back the pH balance of water is to limit the use of items which run on petrol．Instead use products which run on electricity．
Another great thing that all people can do is to learn how to drive cars efficiently．To reduce smoke emission from cars，drivers should ease up as soon as the yellow light rather than slamming on the brakes and they shouldn't rush away as soon as the lights turn green．These small practices help reduce the wastage of petrol．
Limit the use of buses or cars for small things，people can also make use of cycles or walk to cover small distances．
Another great tip which almost all of us can practice is to always keep the vehicle tyres full of air，which will provide users with a better fuel economy．
Turn off your lights，computers and other appliances when not in use．
Learn about the different sources of energy besides fossil （化石） fuels and try to use them in daily life．Many nations like France and Germany are using electrical，nuclear，wind and solar energy on large basis．

Acid Rain
| Problem | Acid rain （71）affects/influences millions of people and becomes a serious environmental threat to our planet today． |
| Occurrence | ●Harmful gases （72）from industries go into the atmosphere and chemical transformation happens． ●Water droplets in the clouds that have taken in the harmful gases come to the （73）earth/ground when it rains． |
| Results | ●It damages the soil and causes water （74）pollution as well． ●It can weaken and even （75）kill/ruin/destroy trees，and will damage buildings in cities． |
| （76）Types/Kinds/Sorts/Categories | ●Wet-in the form of acid rain，acid snow and fog． ●Dry-in the form of acid gas and acid dust． |
| Prevention | ●Use more electricity than petrol． ●Drive vehicles in an （77）efficient way． ●Go to places （78）nearby on foot or by bike． ●Keep the vehicle tyres full of air all the time． ●Turn off any electrical device the moment you stop （79）using it． ●Try to （80）replace fossil fuels with other forms of energy，such as those produced from wind and the sun，wherever possible． |
