            • 2． Blood donation is a wonderful thing done by us．To begin with，extensive studies show that blood plays an important role in medical operation．In donating our blood we are actually saving the precious lives of the sick．Next，being a healthy person，losing 200ml of blood is only a small sacrifice（牺牲） and helps to improve our metabolism （新陈代谢）．Finally，donating blood helps us in forming good character and developing our sense of social responsibility．Blood donation isn't a complicated issue，but we need to keep a few instructions in mind．
              First，don't go for blood donation with an empty stomach．We can eat anything and after having a right diet we'll feel strong and comfortable to donate blood．For the required hemoglobin （血色素） in the body，we can drink lots of fruit juice．For a good blood flow in the body，let's drink at least 6-7glasses of water daily．Completely avoid taking alcohol or caffeine a day before and after donating our blood．We shouldn't smoke half an hour before making blood donation．
              When we're going for blood donation，first tell the nurse to check our hemoglobin level．During the injection we need to take a deep breath and try to calm ourselves down．During blood donation，keep ourselves cool and calm．
              Blood donation is a very fast process，but we need to take care of ourselves after blood donation．For example，take a rest for 15minutes after the donation．Eat something and drink juice after leaving the blood donation center．Make sure not to skip meals after blood donation．Smoking should be avoided up to one hour after blood donation．
              At last be proud of ourselves that we've done a great task in making an attempt of saving someone's life．Blood donation is a social responsibility for every citizen，especially for us，young students．We should do it not because it does us no harm but because it is a noble thing to do and it helps others a great deal．
              (1) What advantage will a healthy person have if he or she loses 20ml of blood？
              ______
              (2) How long should we rest after blood donation？
              ______
              (3) How much water should we drink every day for a good blood flow in the body？
              ______
              (4) Why is blood donation a social responsibility for young people？
              ______
              (5) What do you think of blood donation？（自拟一句作答）
              ______ ．

            • 3．
              Here is what to do if a storm comes your way!
              Hurricanes （飓风） and typhoons are big storms．They can be up to 600miles across and have strong winds at speeds up to 300kph．The storms can last for over a week．When they come onto land，the heavy rain，strong winds and large waves can damage buildings，trees and cars．Storms can also cause injury and death．
              If a hurricane or typhoon is likely in your area，you should：
              ●Listen to the radio or watch TV for information．
              ●Make your house safe by closing your doors and windows．
              ●Make sure you have plenty of water for drinking and cleaning-fill your bath with water to use．
              Leave your home under the following conditions：
              ●If you are told to leave by the authorities （官方）-be sure to follow their instructions．
              ●If you live in a high building．
              ●If you live near the sea or a river．
              ●If you feel you are in danger．
              If you are unable to get out，follow these advice：
              ●Stay indoors during the hurricane and keep away from windows and glass doors．
              ●Close all inside doors and outside doors．
              ●If the storm dies down，do not go outside； it could be the eye of the storm-the winds will pick up again．
              ●Stay in a room on the ground floor．
              ●Lie on the floor under a table．

            • 4． Since 1850，the temperature of Earth's surface has increased about 0.6℃．Scientists predict（预测） it may warm much more by the end of this century．Who's turning up the heat？Well，it seems that we are!Some of this global warming may be natural．However，nearly all scientists now agree that most of it is due to people's actions． Over the past 150years，we've give out large amounts of gases，
              especially carbon dioxide （CO2）to the air． These gases can keep heat near Earth's surface，so more carbon dioxide means more heat is kept near Earth's surface．Global warming may change the weather in ways that lead to more severe（严重的） storms，floods and droughts．

              What can we do to help？Nowadays to live a low-carbon life is quite popular in the world．Low-carbon means to reduce the amount of carbon dioxide．Saving energy and reusing are the key words．In fact，even the simplest everyday activities can make our lives low-carbon．
