The human body is a living machine, and, like all machines, it needs “fuel” to supply it with energy. This is provided by the food we eat. But how much do we need to stay healthy?
The energy value of food is usually measured in calories(卡). A calorie is the amount of heat required to raise the temperature of 1 kg of water by 1℃. The number of calories people need per day is different, as the picture shows. Also, the number of calories you use at any one moment normally depends on the activity you are in. For example, you need more calories for standing than for sitting, more for running than for walking, and so on.
The energy in food is in the form of three kinds of chemical materials—carbohydrate（碳水化合物）, protein（蛋白质） and fat. Carbohydrate provides 3.8 Cal /gm of the energy, protein 4.0 Cal/gm, and fat 8.8 Cal/gm. Each food contains different amounts of these materials, as the round pictures show.
(P= protein      C= carbohydrate    F=fat)

The widespread number of food scandals ( 丑闻) in China is making many people pause before they put their chopsticks in their mouth. They are wondering if the food they are eating is clean, healthy and nutritious or does it contain something harmful that will cause disease?
Most of the food we eat today is processed food( 加工食品). That means the foods we buy in stores and supermarkets, especially packaged foods, are prepared in factories. Chemicals are added to the foods in these factories to make them look better, taste better and last longer on the shelf. The chemicals are supposed to be harmless and there are laws that regulate which chemicals can and cannot be used. Unfortunately, some producers do not obey the laws.
A producer of steamed buns (馒头) in Zhejiang Province was recently discovered to be breaking the law. He was adding yellow dye and other banned chemicals to the buns. He was also taking old buns and using them to make new buns. Most of the buns were sold to schools and eaten by students. . . like you’
Why did he do it? Why did he break the law and endanger people’s health? The answer is simple: he wanted to make more money. It was a moral failing, and this is at the heart of the food scandals in China. Too many people focus on making money and not on the effects their actions can have on others.

DIY, which means Do It Yourself, is quite popular in UK. Lots of stores and supermarkets sell DIY things. TV proprammes show people how to DIY.

English people like DIY. There is a saying in UK – “An Englishman’s home is his castle”. Huge numbers of people spend their holidays making their homes beautiful “castles”. If there is anything that needs fixing around their houses, such as painting the walls or putting in a new shower, they will do the jobs themselves. They share DIY experiences with their friends. More and more people have discovered the joy of DIY. Sometimes people also DIY for saving money. With the economic downturn at present, many people can not afford to buy a bigger house. They are looking at how they can make their house better without spending a lot of money. It is not surprising that DIY is so popular.

  DIY can be difficult. There is a huge market for DIY furniture which people need to put together themselves with a few basic tools. However, people often find it not easy to build a piece of furniture because they can’t understand the instructions. Sometimes the instructions are simple and clear, but the furniture itself is difficult to build. One thing is for sure, though most DIY projects are started with the best intentions, many of them may not get finished. DIY can also be dangerous. For example, anything electrical should be done by a professional worker. Unluckily, many people don’t care about this warning and put themselves in danger. It is reported that in just one year over 230,000 people were hurt while doing DIY in UK, including 41,000 who fell off ladders.

  Therefore, DIY can bring us fun and help us save money, but it is not always as easy as it is thought to be if we bite off more than we can chew. Maybe factories should make products that are easier and safer for us to DIY.
