Climbing Mount Qomolangma, the World's highest mountain, has now become more difficult. The government of Nepal asks climbers to come down the mountain with at least 18 pounds of garbage. That's the average amount of garbage a climber leaves behind on Mount Qomolangma.

    Climbers would leave garbage along the way. This helps climbers keep their bags light, so they would have energy to reach the summit.  The garbage problem in Mount Qomolangma is not new. In 2013, climbers carried down a total of four tons of garbage.

    The new rule came into effect in April of 2014. To make sure it is followed, climbers will have to hand in some money to the officials before they climb the mountain. When they climb back down the mountain, the officials will check them to make sure they bring down the 18 pounds of garbage. If they do, their money will be given back to them.  If not, climbers won't get their money back. Also, the officials won't let these people climb the mountain again.

    Technology is everywhere. We see it any place we go and, in fact, almost all of us carry some piece of technology with us every time we leave the house. What I always forget, though, is just how useful and powerful technology can be when we want to help others.

    There is not a single room in my house that does not have some electronic devices （设备）lying around in it. Whenever I am at home, I am almost always using at least one electronic device. If you walked into my living room on any given day, you would find that, first, I have the television on. At the same time, I usually have my laptop resting on my knee, or I will be using my mobile phone. Even when I'm not at home I am always using my phone, and at work or in cafés, I sit down and connect to the local wireless network on my laptop.

    I must say that I waste a lot of time on the computer and the time I spend on it could be much better spent if I were to take up a little online volunteering.

    The technology we carry about everywhere can have a great power to do good for the world and to help others and recently I discovered just how much online volunteering there is to do in the world. From using your language skills to do translations, to developing and managing projects and helping with IT work, there is so much that so many people can do to help people in their own countries and across the world. The United Nations, in fact, has a huge page with "Volunteers Recruited" on its website.

    This work can support the poor and help charities who cannot pay for staff members. Many organizations only require you to work an hour a week﹣some even less. And the support provided by online volunteers can really help make a difference to those in need.

Next time you make yourself a hot cup of tea or coffee，you might want to let it cool down a bit before drinking. 

Researchers say letting your hot drinks cool off could help you avoid some kinds of cancer. Researchers at the International Agency for Research on Cancer (IARC) found evidence that drinks at temperatures above 65 degrees Celsius, when swallowed, can cause cancer of the esophagus (食道). The researchers examined findings from other studies where tea and coffee were often served at 70degrees Celsius or above. Those studies were completed in Iran, China and South America. 

In developed countries, health experts have linked esophageal cancer to smoking and alcoholic drinks. However, this form of cancer is more common in areas where people drink beverages at very high temperatures. 

In Europe and the United States, many people drink coffee and tea at temperatures around 60degrees Celsius. And they often add milk which lowers the temperature considerably. However，tea﹣drinkers in Iran and mate﹣drinkers in South America often enjoy their beverages at closer to 70degrees Celsius. 

The researchers note that South Americans not only drink their mate very hot，they also drink it through a metal straw. This sends the scalding liquid directly into the throat. 

The findings, however, are good news for coffee drinkers. In 1991, the World Health Organization listed coffee as possibly carcinogenic (致癌的). WHO officials have since changed their position on that listing. They now suggest that the temperature of your hot drink is a greater risk factor than the actual drink itself. 

The results suggest that drinking very hot beverages is one probable cause of esophageal cancer and that it is the temperature, rather than the drinks themselves, that appears to be responsible.

There was a saying in ancient China,"The Winter Solstice (冬至) is as important as the Spring Festival (春节)."

The Winter Solstice became a winter festival during the Han Dynasty. On this day, people would have a rest.

The Winter Solstice, the shortest day of the year, falls on Dec. 22 this year. Northern China has the tradition of eating dumplings on this day, while people in southern China eat tangyuan (汤圆).

The Winter Solstice marks the beginning of deep winter. The important thing during the days of the Winter Solstice is to keep away from cold. We should wear more clothes to stay warm and try to reduce unnecessary outdoor activities.

The Winter Solstice is also a time for family gatherings. However, Tang Xiaoqian, an 11-year-old girl, will have to spend the festival with only her grandmother. She hasn't seen her parents for four years. In fact, there are lots of children like her in her village. They are growing up without their parents. They are called left-behind children (留守儿童).

To make more money, a number of parents have to leave their children behind and go to cities to look for jobs. They can't go back home to celebrate festivals with their children and even can't see their children for years.
