A new study warns that about thirty percent of the world’s people may not have enough water by the year 2025.

A private American organization called Population Action International did the new study. It says more than 335 million people lack enough water now. The people live in 28 countries. Most of the countries are in Africa or the Middle East.

P-A-I researcher Robert Engelman says by the year 2025, about 3,000 million people may lack water. At least 18 more countries are expected to have severe water problems. The demand for water keeps increasing. Yet the amount of water on the earth stays the same.

Mr. Engelman says the population in countries that lack water is growing faster than in other parts of the world. He says population growth in these countries will continue to increase.

The report says lack of water in the future may result in several problems. It may increase health problems. Lack of water often means drinking water is not safe. Mr Engelman says there are problems all over the world because of diseases, such as cholera, which are carried in water. Lack of water may also result in more international conflict. Countries may have to compete for water in the future. Some countries now get sixty percent of their fresh water from other countries. This is true of Egypt, the Netherlands, Cambodia, Syria, Sudan, and Iraq. And the report says lack of water would affect the ability of developing to improve their economies. This is because new industries often need a large amount of water when they are beginning.

The Population Action International study gives several solutions to the water problem. One way, it says, is to find ways to use water for more than one purpose. Another way is to teach people to be careful not to waste water. A third way is to use less water of agriculture.

The report also says long-term solutions to the water problem must include controls on population growth. It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.

There have always been a lot of commonly believed but false ideas about being fat and doing exercise. Some people believe that they can’t help putting on weight as they get older, while others hold that if they stop exercising, their muscles will turn into fat. Here are some more myths:

I’ll never lose weight --- I come from a fat family.

Wrong! While we can’t change the body type we are born with, we can’t blame our genes for making us fat. There’s plenty of evidence that fatness runs in families, and the main reason is that they share the same habits of eating too much and exercise too little.

I am fat because I burn calories slowly.

Wrong! Fatness is not caused by a slow metabolism (新陈代谢). If fact, although fat people consume more energy that slim people, they also fail to realize how much they eat! Keeping a diary can help you work out your daily food intake more accurately.

Exercise is boring.

Wrong! Anything will become boring if you do it many times. The key is to develop a balanced and varied program that’s fun as well as progressive. If you enjoy a Sunday walk, take a different route. If you do Yoga, try a tai chi class. If you like swimming, set yourself a distance or time challenge.

No pain, no gain.

Wrong! Exercise is not meant to hurt. Indeed, pain is your body telling you something’s wrong, and continuing to exercise could lead to serious injury. You may experience mild discomfort as you begin to exercise regularly, but this your body adapting to the positive changes in your lifestyle and the aches should disappear relatively quickly. If you don’t, rest and seek medical advice.

1.What does the author think about being fat?

A. It is the family genes that make people fat.

B. It is the result of people’s unbalanced lifestyle.

2.According to the author, how can we make exercise more interesting?

A. By taking varied exercise.    B. By choosing simple exercise.

C. By doing regular exercise.    D. By sticking to outdoor exercise.

3.What is the author’s opinion about “No pain, no gain” in exercising?

A. Keeping fit is essentially a painful experience.

B. Exercise should be stopped if continuous pain is felt.

C. Pain in exercise is a precondition(前兆) for reaching your goal.

D. Getting used to pain leads to positive changes in your body.

4.What is the purpose of the passage?

I have been flying since I was three years old. I am now 27 and cannot ever remember being afraid of flying until I was around 20. Suddenly, it seemed to come from nowhere. I began to be afraid of flying.

Two weeks before I was to fly I would have nightmares every night, all of which were centered on a plane crash. This would obviously add to my anxieties. The turning point for me was when I had to go on a business trip to Germany. My boss and my husband were with me, but nobody was allowed to talk to me. I was quiet and on the verge of (濒于) tears right up until boarding. On the flight I was even worse. I was crying, shaking and my palm were sweaty. It sounds so ridiculous, but if you have a fear of flying you will understand my distress.

I got home and my fear was getting out of control. It was upsetting for my husband when we were going on holidays together. I would never be excited because I didn't want to fly as I was certain the plane would crash, or we would be hijacked, or there would be a bomb on board, etc.

I thought about paying for expensive hypnotism (催眠术) to see if that would help me but I also wanted to try and help myself first. That was when I found this book.

I read the book as soon as it arrived. It answered the questions I had. After that, when I had a flight coming up, I read a few chapters of the book every night for 2 weeks before the flight. I also took the book in my hand luggage so it was there to refer to if I felt fearful during a flight.

This book is AMAZING and a MUST-HAVE for any nervous flyer.
