Want to travel easily? Here are some tips that help you reduce the size of your luggage.

    Roll clothes instead of folding them. Many people try to fold their clothes into their little suitcase.{#blank#}1{#/blank#} It actually makes far more sense to roll your clothes rather than fold them. Starting from the bottom, roll up your clothes into very tightly packed cylinders (圆柱体) which you can stack (堆叠) on top of each other.

    Use vacuum bags (真空袋), when possible.{#blank#}2{#/blank#} Buy some vacuum bags and seal all of your clothes up tightly. Having all of your luggage vacuum sealed will reduce the size of your items greatly. That will allow you to take more of what's needed.

    Always take travel bottles. Even though you are allowed to take full sized bottles in your suitcase, to make sure that you are under the weight allowance, it's recommended that you still stick to travel-sized bottles.{#blank#}3{#/blank#} Besides, it will also prevent you from wasting any product. If you do run out of anything while you are on holiday, you can always buy more.

A great way to prevent packing clothes that you won't end up wearing is to research what the weather is going to be like where and when you go on holiday.{#blank#}5{#/blank#} You can know how hot it's likely going to be, as well as how much rain on average the destination receives each month.

    In the latter part of the 20th century, child labor remains a serious problem in many parts of the world. Studies carried out in 1979, the International Year of the Children, showed that more than 50 million children below the age of 15 were working in various jobs often under dangerous conditions. Many of these children live in underdeveloped countries in Latin America, Africa, and Asia. Their living conditions are crude and their chances for education small. The poor income they bring in, however, is necessary for the survival of their families. Frequently, these families lack the basic necessities of life—adequate food, decent（得体的、合适的）clothing and shelter, and even water for bathing.

    In some countries industrialization has created working conditions for children that are comparable to the worst features of the 19th-century factories and mines. In India, for example, some 20,000 children work 16-hour days in match factories.

    Child-labor problems are not, of course, limited to developing nations. They occur wherever poverty exists in Europe and the United States. The most important efforts to eliminate（根除）child-labor abuses throughout the world come from the International Labor Organization (ILO), founded in 1919 and now a special agency of the United Nations. The organization has introduced several child-labor conventions（规定）among its members, including a minimum（最低）age of 16 years for admission to all work, a higher minimum age of specific types of employment, compulsory（强制的）medical examinations, and It depends on voluntary obedience（服从）of member nations.

    This year's flu season is pretty scary. To try to minimize the effects, public officials are still urging anyone who hasn't yet gotten their flu shot to get one as soon as possible. However, even if every single person got a shot in the arm, the vaccine(疫苗)—with its excellent 36 percent effectiveness—would not prevent everyone from getting infected with the annoying virus. Knowledge is power, so here's what goes on in your body when you come down with the flu.

    The influenza virus primarily attacks your nose, throat, and the tubes that lead to your lungs. But the flu is so much more than that. Your muscles ache, your head hurts, and your appetite goes down, among other things. To our surprise, almost all of these symptoms have less to do with the virus itself than with your immune(免疫的)response to them. Unfortunately, the very defense you have in place to get rid of the flu is the reason you feel so painful when you recover.

    The virus usually enters through your mouth, typically by way of your hands. But it takes a few days for symptoms to set in. While this process might cause some harm to your nose and throat, it's nothing major, and nothing like the symptoms that typically accompany a bad or even mild case of the flu.

    The real fun starts when your immune system begins to fight. Your immune system comes in two parts: the innate system and the adaptive. The innate immune system is essentially an all-purpose tool. As soon as your body senses the presence of any injury or invader (入侵者), the innate immune system launches into action by producing tiny proteins called cytokines and chemokines. The cytokines reproduce almost immediately and start to attack the virus. This increase in immune cells creates an serious inflammation(炎症) throughout the body. But the worst is still to come. Meanwhile, the chemokines work with the adaptive immune system to help create T cells. These cells are a special type of white blood cell that works in a much more specific way: They find the influenza virus, identify what's special about it, and create something unique on their surface that finds and destroys similar invaders.

    American and British people both speak English of course. But sometimes it does not seem like the same language. In fact, there are some important differences between British English and American English.

    First of all, they sound very different. Often, Americans don't say each word separately. They say several words together. Americans may say "I dunno" instead of "I don't know". Or they may say "Whaddaya say?" instead of "What do you say?" However, the British are more careful in their speech. They usually say all the words and keep them separate.

    Sound is not the only difference between British English and American English. Words sometimes have different meanings too. Some American words are never used in England. The same thing is true of some British words in America. For example, the vocabulary for cars and driving is very different. Americans drive trucks, but in England people drive lorries.

    Many expressions are also different in the two countries. In England，if you are going to telephone your friends, you "phone them up". In America, you "give them a call". When you are saying goodbye in England you might say "Cheerio!" In America you might say "See you later."

    There're also some differences in grammar. For example, Americans usually use the helping verb "do" when they ask a question. They say "Do you have a storybook?" But the British often leave out the helping verb. They say "Have you a storybook?"

    All these differences can be confusing if you are learning English. But most languages are like this. Languages change over time. When people live in separate places, the languages change in different ways. This is what has happened to English. It can also happen to other languages, such as French. Many people in Canada speak French, but their French is very different from the French of France.
