Ever since news of widespread food recalls caused by a carcinogenic dye broke, there has been confusion（混淆） over possible links to the country of the same name, but Sudan officials say there is no connection whatever．

   Sudan 1 is a red industrial dye（颜料） that has been found in some chilli powder, but was banned in food products across the European Union (EU) in July 2003．

   Since the ban was put in place, EU officials have been trying to remove some food products from the shelves．So far 580 products have been recalled．

Last week Sudan’s Embassy in the United Kingdom asked the Food Standards Agency (FSA) for clarification(澄清) of the origin of the dye’s name．

   Omaima Mahmoud Al Sharief, a press official at Sudan’s Embassy in China, explained the purpose of the inquiry was to clear up any misunderstanding over links between the country and the poisonous dye．

　　"We want to keep an eye on every detail and avoid any misunderstanding there," she said．"Our embassy to Britain asked them how the dye got that name and whether the dye had something to do with our country．But they told us there was no relationship．"

   The FSA, an independent food security watchdog in Britain, received a letter from the Sudanese embassy last week．

　"They asked us why the dye is named Sudan, however, we also do not know how it got the name," she said．"People found the dye in 1883 and gave it the name．Nobody knows the reason, and we cannot give any explanation before we find out．"

　　Forests have always been useful and important to man who makes use of them in many ways. Every day trees are serving man everywhere. Trees supply man with fruits and building materials in the form of wood. Without trees it would be impossible to build houses, boats, bridges and so on. Furniture such as desks, chairs and beds is made of wood. Trees can stop man from terrible heat. They're also useful in preventing good and rich top soil from being washed away during heavy rains.

　　If there were no trees, heavy rains would wash away the rich top soil that is so important to plants. The result is that the land will become a desert. There are plenty of desert areas in the world. A long time ago these desert areas used to be very rich areas, but man in the past had no enough knowledge about science of nature, they cut down too many trees in the area where they lived and never planted new ones.

It is Saturday afternoon. You and your friends are planning to go to the movies and then spend the night together. Just as you start to get ready, your dad reminds you that it is your aunt's birthday and the whole family is going out to dinner to celebrate. How can this possibly end without a huge argument?

　　One of the greatest sources of tension (紧张情绪) between teenagers and their families is the struggle to balance personal desires with family expectations. As you are getting older, you are becoming more independent and more interested in being with your friends.

　　However，at the same time，your family is trying to figure out how to deal with these changes. While you once spent most of your free time with your family, you are now often absent from home. Parents may get their feelings hurt. Or they might feel that they are losing control of their family during this period. You might feel angry that so many family demands are placed on you.

　　There are a few things you can try to make it a little easier to ease (缓解) the tension.

　　* Make your plans in advance. Ask your parents if there is anything else planned at that time.

　　* When something with your friends interferes (冲突) with a family event，try to figure out if there is any way you can do both.

　　* Suggest something you would really like to do with your family. Sometimes parents feel better just knowing their teenager wants to spend time with them.

　　Some of the time you won’t be happy with the outcome (结果). You might either have to disappoint your parents or have to miss out being with your friends. However, if you show consideration for the feelings of both your family and your friends，you can solve the problem in a tender way.
