     Have you seen the movie The Day After Tomorrow In the movie,the world becomes a large ocean because of global warming. It seems impossible,but if we don't cut carbon emissions (碳相卜放) to stop the temperature from rising,there will be real disasters.

   What is global warming? Global warming refers to an average rise in the Earth's temperature,which in turn causes changes in climate. Over the past 100 years,the Earth's temperature has risen one degree. A warmer     Earth may lead to changes in rainfall,melting of icebergs and an impact (影响) on plants,animals and humans. As the sea level rises,some countries are in danger of disappearing.

   Carbon dioxide is the major greenhouse gas that causes global warming. It mainly comes from factories and cars which burn fossil fuels (化石燃料) like coal and gasoline (汽油) . Governments hope to cut carbon emissions by 25 —45 percent by 2020. The EU plans to cut emissions by 20 percent by 2020. It can cut as much as 30 percent if other developed countries take action,too.

   For developing countries,to grow their economies,they have to build more factories,and carbon dioxide will be a byproduct (副 产品) . So,cutting emissions means slowing down their development. However,they are looking for new ways out. For   exmple,China says it will continue to develop solar (太阳的) and wind power,and will try to cut carbon emissions significantly hf 2020.

46. What can we do to prevent global warming?

   A. Stop using fossil.

   B. Use solar and wind power more often.

   C. Try to lower sea level.

   D. Slow down the development of the country.

47. What is the writer's purpose in writing this article?

   B. To call for more people to work to cut carbon emissions.

   C. To blame the developed countries for not taking action.

   D. to tell people about global warming and carbon emissions.

48. According to the last paragraph,we can infer that .

   A. China is trying to cut carbon emissions and grow the economy at the same time.

   B. China is taking the least active role in cutting carbon emissions.

   C. solar and wind power can replace carbon dioxide.

   D. developing countries are slowing down their development.

    It's a terrible feeling. You feel sick,tired,and the room won’t stop spinning. Whafs wrong with you? Perhaps you are experiencing motion sickness. Motion sickness,also called travel sickness,is a common experience. Depending on how you travel,it can be named carsickness or seasickness. You may get the feeling when you try to read a book in a car or on a boat. Even astronauts train hard to fight motion sickness before going into space.

   But why do we get motion sickness? And how can we prevent it?

We have four functions which sense movement. Our eyes see if we are moving. The ears contain special liquid to sense direction,while our skin knows what part of the body is touching the ground. Our muscles react to movement,like when you stop yourself swaying (摇摆) when the car sharply turns. When these four functions get puzzled,they start sending mixed messages to our brain,and we develop motion sickness.

   Just think: when we’re in a moving car and reading a book. Our eyes see we are moving when we look out of the window,but still (静止的) when we read. The ears hear the car moving,yet the skin says we are sitting dowh. Muscles may only feel movement if the car turns. So our senses are all out of balance,and we start to feel ill.

But here's some good news to fight motion sickness. Choose an aisle (过道) seat on a plane,train and sit in the front of a car. Avoid standing. Always face the same way you’re traveling and leave your books at home.

    Why don't some people get motion sickness? Scientists are still working on it,but they think genes may play a part.

    A.often stand up to look out

49. From the passage,we can infer that .

   A. astronatats don't get motion sickness before going into space

   C. you may get carsickness when you read books in a parked car

   D. scientists haven’t found why people get motion sickness

    If you watch what you eat and eat it smartly,you will live a better life.

  Who help you most in your everyday life,families,charities,or friends? Don’t forget about your neighbours!Neighbours help you more than anyone else in your daily life. So it is important to have good neighbours.

    What does it need to be a gocxl neighbour? Here is some advice : Good fences (概栏) make good neighbours. One of the most important things is to respect a person's privacy (隐私) . If you go over as soon as new neighbours move in,they may think you are going to come over at all hours of the day,not respecting their privacy.

    It is always a good idea to be friendly to everyone in the neighbourhood. This can not only put you on good terms (关系和 睦) with them,but also will be a kind of protection for your family and home. If you are friendly to them,they are much more likely to watch out for anything wrong going on around your home while you are out and let you know if anything happens.

    Another way of being a good neighbour is to be helpful in their hour of need. If you see that they are in need of a helping hand,it is good to offer your help. They will do the same if you are in trouble.

   In a word,if you respect a person's privacy,treat them kindly and be helpful when you see they are in need,you will be a great neighbour and anyone would be happy to have you next door!
