The human brain weighs about 1.4 kilograms, but it can hold much more information than most computers. However, there is another difference between humans and computers. Computers don’t forget information they are given. No one remembers everything, and luckily we don’t usually have to. But everyone can improve their memory if they want to. Here are some suggestions.

★Try to use new information at once. For example, if you meet someone who says “Hi! I’m Carlos.”, don’t just say “Hello!” Repeat the person’s name, Carlos.

★Write out what you need to remember again and again. This will help you keep it in mind longer, especially for remembering formulas(公式) or facts.

★Always review information. If you bring what you’ve learned back to your mind, they become easier to remember. For example, before you go to sleep, it’s a good idea to review the new things you learned that day.

★Discuss with a friend. It is always easier to remember things through discussions. You can have a discussion about what’s right and what’s wrong, and it will lead to the right answer.

★永远不要说你记忆力不好。You can always do something to help improve your memory. And everyone’s memory gets better if they use it often enough.

October the 16th is World Food Day, a day of action against hunger. The UN started the day in 1979. The day hopes to raise public awareness of many food-related problems and end hunger someday.

Over the past twenty years or so, we have seen a great reduction of people living with hunger. Back then, about one in six people went to bed hungry most nights. Now it's about one in every nine. However, that still leaves some 795, 000 hungry people around the world. Sadly, the victims of hunger are mostly women and children. Nearly 5 million children under the age of 5 die of the malnutrition（营养不良）each year.

What's causing food shortages? First, there are more droughts（干旱）and floods. The farmers suffer crop failures because of weather. Also, with the growing population, feeding everyone becomes more difficult. There are about seven billion people in the world. By 2050, the world population will be more than nine billion. Another big problem is food waste. According to the UN, more than one third of all food produced worldwide is wasted each year.

Would you believe that we waste enough food each year to feed more than one billion people? It's time to get serious about cutting down on food waste. In Chinese restaurants, many times, over-ordering leads to unnecessary waste. So, don't order too much. If you've stored more food than what you need, why not donate it to the food banks?

World Food Day shouldn't be the only day we act. It is about zero hunger. Let's work together!

Many of us don’t pay much attention to the importance of eye care. It is said that if you take care of your body, then you can surely be healthy. That is why we should give a lot of care to our eyes. Natural eye care should be put into the most important place.
