CCTV reported that every year Chinese people throw away a lot of food which can feed 200 million people for a year.

      Do we have too much food? Of course not. According to the UN World Food Programme, there were 900million hungry people all over the world in 2013. About six million children die of hunger every year.

     So think about it. We should say no to people who waste food every day. An old saying goes, “Every grain on the plate comes from hard work.” It tells us everybody must save food.

      Luckily, a number of people have realized the importance of saving food. Li Hong, a waitress in a restaurant in Jiangsu, once lost her job because she took some leftover(剩余的) food home for her son. But many people were by her side and criticized (批评) the waste of food.

      What should we do in our daily life to stop wasting food? We can do many things to prevent it from happening. Here are some tips:

     Don't order too much food in a restaurant. Only order as much as you can eat. If you can't eat all the food you order, take the rest of it home.

      Don't be too picky(挑剔的) about food. Some food may not be tasty, but put body need it.

Don't keep too much food at home, especially for fruit and vegetables.

    Several Asian hospitals are doing experiments with tele-medicine. Tele-medicine is a technology that allows doctors to "see" patients without them being in the same place. This is made possible through high-speed communication networks(网络). At both ends of the line, the way of video-meeting lets them see and talk to each other. Blood pressure (血压) and body temperature are directly shown on computers.

    Tele-medicine is already in wide use in some places such as the United States and Germany. Among other uses, village doctors hold "consultations (会诊)"with far-away experts(专家). The experts can also help them during operations.

    Tele-medicine has been slow to reach Asia because of high costs besides other reasons. When things improve, this technology will develop very fast. Chinese University of Hong Kong's medical school has joined a big hospital in Beijing, and Thailand is building a tele-medicine station connecting 20 areas.

    Tele-medicine will do good to patients because doctors from different places can see them and give their medical advice. The help is quite important if the disease is an unusual one. It also helps spread medical knowledge among experts.

    As tele-medicine develops well, its costs will be lower and it will become very popular in the medical field.
