For many Chinese people, potatoes are considered as a kind of vegetable. But in the future, this will no longer be the case（情况）. Potatoes will be added to China's list of food products, like rice, wheat and corn. And potato starch（淀粉） will be mixed into bread, steamed buns（馒头）and noodles to suit（适合） Chinese people's tastes and eating habits.

In fact, potato is more than just a main food of diet in America. In many ways, it's an integral（不可或缺的）part of the American pop culture.

Is it difficult for you to remember things? I`d like to tell you some ways to improve your memory, so you shouldn't feel upset.

  My first advice is that if you want to remember something well, you have to review it regularly(有规律地). You might review the material two days after you learn it, then a week later, then two weeks later, and then a month later. After a month you will find that you can easily remember the material.

My second advice is to use a colored pen to highlight （标注）the important parts on your book. This will help you in two days. First, it will help you pay attention to the most important parts when you learn the language. It is always easier to remember only the key points. Second, this will make reviewing easier. When you open your book, the colored parts will show you the most important things quickly. In this way, you don't have to review all the material again.

  Another piece of advice is to use the proper time well. First, review all the information in your mind right before you go to sleep. Your brain is working while you are sleeping. If you think about the information before you go to sleep, you might be able to remember it better. Another good time for memorizing information is in the morning because you have just rested and your brain is fresh and clear. So you might also try to review the important information in the morning.

    Although the idea seems a little unrealistic （不现实的），it is necessary．According to a new report，American people produce the largest amount of the litter in the world．Each person produces almost 4.6pounds of litter every day．More than half of the litter which is put into landfills is harmful ． Actually，this is bad for the environment．Besides this，more landfills（填埋场） are needed．

    "Nobody wants to have a landfill lying near his house，"said Jon D．Johnson from the Environmental Protection Agency，which helps to carry out"zero waste"activity．"There are not enough landfills，so we can't put all our litter into them．We should try to recycle it as much as we can．"
