Organic food has no nutritional or health benefits over ordinary food，according to a major study．
Researchers from the London School of Hygiene & Tropical Medicine said consumers were paying higher prices for organic food because of its imagined health benefits，creating a global organic market worth an estimated $48 billion in 2007．
A systematic review of 162 scientific papers published in the scientific literature over the last 50 years，however，found there was no significant difference．
“A small number of differences in nutrient content were found to exist between organically and conventionally(通常)produced foodstuffs，but these have nothing to do with public health，” said Alan Dangour ，one of the report's authors．
“Our review indicates that there is currently no evidence to support the selection of organically over conventionally produced foods on the basis of nutritional superiority ．”
The results of research，which was commissioned by the British government’s Food Standards Agency，were published in the American Journal of Clinical Nutrition．
Sales of organic food have fallen in some markets，including Britain，as a slowdown in economic growth has led consumers to cut back on purchases．
The Soil Association said that growth in sales of organic products in Britain slowed to just 1.7percent，well below the average annual growth rate of 26 percent over the last decade．

You wake up in the morning, the day is beautiful and the plans for the day are what you have been looking forward to for a long time. Then the telephone rings, you say hello, and the play starts. The person on the other end has a sad tone in his voice as he starts to tell you how terrible his morning is and that there is nothing to look forward to. Yon are still in a wonderful mood(心情)? Impossible!
Communicating with negative people can wash out your happiness. It may not change what you think, but communicating long enough with them will make you feel unhappy for a moment or a long time.
Life brings ups and downs, but some people are trapped in the wrong idea that life has no happiness to offer. They only feel glad when they make others feel bad. It is not strange that they can hardly win others’ pity or respect.
When you communicate with happy people，you will stay happy. When the knife of a negative person is put in you, you feel the heavy feeling that, all in all, brings you down.
Sometimes we have no choice but to communicate with negative people. This could be a co-worker, or relative. In this situation, say what needs to be said as little as possible. Sometimes it feels good to let out your anger back to the negative person，but all this cannot reduce your bad feelings and they won’t feel ashamed(羞愧) of themselves about that.
Unhappiness often influences happiness without even being realized. The depressing(令人沮丧的) words of another at the start of the day can be with you throughout the rest of your day，which makes you feel bad and steals your happiness. Life is too short to feel unhappy.

Saving money is easy when you don’t have anything to spend it on, but what happens when things come suddenly that demand some of your hard-earned money? These are called expenses (开销).
Chances are, most of your basic living expenses — food, shelter, clothing, medical care — are covered by your family. But perhaps you and your family have agreed that you’ll pay for certain other expenses out of your own money, such as cell phone bills, after-school snacks, jewelry, or club fees (费用).
Expenses that happen regularly, like every week or month, are called “fixed” expenses. The good news is that because you know when these expenses are coming, you can plan for them. But life is full of surprises, and sometimes these surprises turn into expenses, too. You might have an emergency like fixing a flat tire on your bike, or something unusual like the class trip to Six Flags. These are called “unexpected” expenses and if you are smart with your money, you’ll plan for these as well.
Here’s a secret when it comes to saving money: if you think of it as a regular expense, it’ll be easier to put a certain amount aside. Tell yourself that the $20.00 you are trying to save up every month is something you must do, and there’s no getting around it.
What kinds of fixed expenses do you have? Can you think of any unexpected expenses that have come up for you in the past? Can you think of any you might have now or in the near future?
| A．Money spent on medicine. | B．Money spent on clothing. |
| C．Money spent on sports. | D．Money spent on meals. |
| A．Changing a new tire. | B．House rent. |
| C．Buying snacks. | D．Paying for cell phone bill. |
| A．Trying your best to prevent emergencies. |
| B．Earning as much as you can after class. |
| C．Cutting most of your expenses. |
| D．Putting some money aside as a regular expense. |
| A．you can’t let out this secret |
| B．there is no other choice |
| C．you have other solutions to it |
| D．there’s no point in arguing about it |
I was very disappointed not to be able to go to the jazz concert last Friday. The advertisement in the paper said that you could buy tickets at the theatre box in Richland Hills any day between 10:00 and 4:00. Since I work from 9:00 to 5:30, the only time I could go to the theatre was during my 45-minute lunch break. Unfortunately, the theatre is on the other side of the town, and the bus service between my office and Richland Hills is not very good. But if you are lucky, you can make the round trip in 45 minutes.
Last Monday, I stood at the bus stop for fifteen minutes waiting for the bus. By the time I saw one come around the corner, there was not enough time left to make the trip. So I gave up and went back to the office. The same thing happened on Tuesday, and again the next day. On Thursday, my luck changed. I got on a bus right away and arrived at the theatre in exactly twenty minutes.
When I got there, however, I found a long line of people at the office. I heard one man say he had been waiting in line for over an hour. Realizing I would not have enough time to wait in line, I caught the next bus and headed back across the town. By Friday I realized my only hope was to make the trip by taxi. It was expensive, but I felt it would be worth it to hear the concert. The trip by taxi only took 10 minutes, but it felt like an hour to me. When I got to the theatre, I was relieved to see that nobody was waiting in line. The reason, however, I quickly discovered, was that they had already sold all the tickets.

It was a winter morning, just a couple of weeks before Christmas. While most people were warming up their cars, Trevor, my husband, had to get up early to ride his bike four kilometers away from home to work. On arrival he parked his bike outside the back door as he usually does. After putting in 10 hours of labor, he returned to find his bike gone.
The bike, a black Kona 18 speed, was our only transport. Trevor used it to get to work, putting in 60-hour weeks to support his young family. And the bike was also used to get groceries, saving us from having to walk a long distance from where we live.
I was so sad that someone would steal our bike that I wrote to the newspaper and told them our story. Shortly after that, several people in our area offered to help. One wonderful stranger even bought a bike, then called my husband to pick it up. Once again my husband had a way to get to and from his job. It really is an honor that a complete stranger would go out of their way for someone they have never met before.
People say that a smile can be passed from one person to another, but acts of kindness from strangers are even more so. This experience has had an amazing effect in our lives because it strengthened our faith in humanity(人性)as a whole. And it has influenced us to be more mindful of ways we, too, can share with others. No matter how big or how small, an act of kindness shows that someone cares. And the results can be everlasting.
