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.

    The tiger is the largest wild cat in the world. It is the king of animals. Tigers often eat 5kg of meat for a meal. Tigers can see very well in the dark. They often hunt at night. Sometimes they can eat 27kg of meat at one night. Most members of the cat family dislike water, but tigers enjoy water. They are good at swimming. Many animals live in groups, but tigers live alone（单独地）, except for（除了） mothers and their young babies. A mother tiger usually has two or three babies at one time. She takes care of them by herself.

    There were eight kinds of tigers in the world, but three of them died out（灭绝）. There are only about 3200wild tigers in the world now because people kill tigers and destroy the places where they live.

    The kiwi lives only in New Zealand. It is a very strange bird because it can not fly.

    The kiwi is the same size as a chicken. It has no wings or tail. It doesn't have any feathers(羽毛)like other birds. It has two feet and each foot has four toes. Its mouth is very long.

    A kiwi likes to have a lot of trees around it. It sleeps during the day because the sunlight hurts its eyes.

    It can smell things with its nose. It is the only bird in the world that can smell things. The kiwi's eggs are very big. There are only a few kiwis in New Zealand now. People never see them. The government says that people can't kill kiwi. New Zealanders want their kiwis to live.

    There is a picture of a kiwi on New Zealand money. People from New Zealand are sometimes called kiwis.

    Inventions usually make a big difference to people's lives. Do you have any great inventions at home? Do they help you a lot in your life or bring you much fun? Here are some of the most useful inventions in families according to a survey.

Could you spend 24 bours without the Internet? I'm not sure how I'd deal with it. These days we all depend heavily on technology, you may or may not be surprised by the results of some recent research about the effects of online and digital （数字的） technology on people's lives. More than half of the people who were questioned said they'd feel "upset" without an Internet connection even for a brief period of time, which is, about 15-30 minutes when they were away from the Internet. 

The scientists also challenged people to spend one whole day without using technology and then report back on what it was like. Some people were surprised that they could not even turn their phones to silent. Nearly fifty percent of them said they felt lonely when they weren't using social media. According to the research, it is harder for the younger people to give up technology. They said that the modern technology has already become a part of their lives. However, there are about 25% of people actually said they felt freer without an Internet connection. It meant they found time to do something they wouldn't usually do such as reading a novel. Some of them said they enjoyed spending more time talking to family and friends face to face. 

So, what about you? As a middle school student, could you take the Internet challenge and spend 24 hours without going online? Or would it be a bad dream for you? Here we have different opinions from Chinese students aged from 12-16, maybe they'll be able to help you with your Internet use.
