  Napping(小睡)after learning something new could help improve your memory--- as long as you dream, scientists say.

  They found people who dream about a new task do it better on waking than those who do not sleep or do not dream.

  Volunteers were asked to learn the layout(布局,设计)of a 3D computer maze(迷宫)so they could find their way several hours later.Those allowed to take a pap and who also remembered dreaming of the task, found their way to a landmark quicker.

  The researchers think the dreams are a sign that unconscious(无意识的)parts of the brain are working hard to process information about the task..

  Dr.Robert Stickgold of Harvard Medical School, said dreams may be a marker that the brain is working on the same problem at many levels.

  Study tips

  Co-author Dr.Erin Wamsley said the study suggests our non-conscious brain works on the things that it deem(认为)are the most important.

  “Every day we are gathering lots of information and new experiences,” she said.“It would seem that our dreams are asking the question, “How do I use this information to inform(影响)my life?”

  The scientists say there may be ways to use this phenomenon(现象)for improving learning and memory.For example, students might be better studying hard before bedtime, or taking a nap after a period of afternoon study.

What do you do if you're stranded(处于困境的)on a lonely island? Surely you need to find a way to get in touch with the outside world. Your best chance of doing this is to draw the attention of a passing plane.
  Body signals(信号)
  Pilots from different countries understand body signals if they have the correct training. When you wave your arms up and down in a straight line, it means "yes". When you point downwards and swing your arm from side to side, it means "no". If you want the pilot to know that it's safe to land, push your hands out in front of you and bend(弯曲)your knees. If you want to say that it's not safe to land, put your arms in the air and move them to one side.
  Smoke signals
  The smoke from a fire can be seen from far away, so it's a good way to draw attention. If the weather is dry, it isn't hard to start a fire. Remember, however, that fires can be very dangerous if they get out of control. Never light a fire unless you're sure that it can't spread. If the ground is dark, light smoke can be seen more easily. Green grass and leaves produce light smoke.
  Ground-to-air signals
  It's a good idea to build some signals, too. Use large pieces of wood to make the symbols(标记). If you can't find any wood, use earth. Some useful symbols are:
  F "I need food and water."
  II "I need medicine."
  I "I am badly hurt."
  X" I am unable to move from here."
  Pilots' replies
  If the pilot lowers the plane's wings from side to side, this means "message received and understood". (At night, the pilot flashes the plane's green lights.) If the pilots flies the plane in a clockwise circle, this means "message received but not understood".(At night, the pilot flashes the plane's red lights.)
However, there is no signal which means "message not received". Why not?
【小题1】 Which picture means "it's not safe land"?

 
【小题2】 What can we learn from the passage?
A.Swinging your arm from side to side means "yes".
B.If the ground is dark, light smoke can't be seen.
C.If you need some medicine, make a symbol "II".
D.The pilots make replies with a blue light at night.
  【小题3】 What is the passage mainly about?
A.The explanation of building signals on an island.
B.The importance of making signals on an island.
C.Ways of sending out signals on a lonely island.
D.Ways of receiving signals from a lonely island

What are you going to do if you are in a burning house? How will you escape? Do you know how to save yourself? Please read the following passage.

   Escaping a fire is a serious matter. Knowing what to do during a fire can save you life. It is important to know the ways you can use and show them to everyone in the family, such as stairways and fire escapes, but not lifts.

  From the lower floors of the buildings, escaping through windows is possible, learn the best way of leaving by windows with the least chance of serious injury.

  The second floor window is usually not very high from the ground. An average person, hanging by the finger-tips will have a drop of about six feet to the ground. It is about the height of an average man. Of course, it is safer to jump a short way than to stay in a burning building.

  Windows are also useful when you are waiting for help. Be sure to keep the door closed. Or smoke and fire may be drawn into the room. Keep your head low at the window to be sure you get fresh air rather than smoke that may leaked(渗) into the room.

  On a second or third floor, the best windows for escape are those that open onto a roof. From the roof a person can drop to the ground more safely. Dropping onto cement(水泥) might end in injury. Bushes(灌木丛) and grass can help to break a fall.
