"Earworms", some people call them. Songs that get stuck in your head go round and round, sometimes for days, sometimes for months. For no clear reason you cannot help yourself from humming or singing a tune by Lady Gaga.
To a psychologist, the most interesting thing about earworms is that they show a part of our mind that is clearly outside of our control. Earworms arrive without permission and refuse to leave when we tell them to. They are parasites (寄生虫) living in a part of our minds.
If you have got an earworm you can suffer an attack of it simply by someone mentioning the tune, without having to hear it. This proves that earworms are a part of long-term memory. Humans have an "inner ear", for remembering phone numbers, for instance. When it gets infected with earworms, rather than review our plans for the day, or lists of things to remember, the inner ear gets stuck on a few short bars of music or a couple of phrases from a song. A part of us that we normally do not have to think about, that should just do what we ask, has been turned against us, upsetting us with a request that we never asked for. The mind is an inner world which we do not have complete knowledge of, or have control over.
Fortunately psychology can provide some advice on how to deal with an uncontrollable mind. Consider the famous "don’t think of a white bear" problem, which tells you to try not to think about white bears, or to do something else, to avoid both thinking of the white bear and not thinking of the white bear. For earworms, the solution may be the same. Our inner ear has become infected with an earworm. This is a part not under our control, so just sending in instructions to "shut up" is unlikely to be of much help (and has been shown to make it worse). Much better is to employ the inner ear in another task. If your mind is poisoned by Brittany Spears’ Toxic, for instance, then try singing Kylie Minogue’s Can’t Get You out Of My Head. Let me know if it works!

 “Who needs a shopping mall if you have Taobao?” says Wang Lin, 28, a writer in Beijing.

Taobao, China’s largest online shopping site (网上购物站), has become an important part of Wang Lin’s life. She spends lots of money on Taobao.

A growing number of Chinese Internet users like Wang have found the joys of online shopping. Most online shoppers are students or young people. More women shop online than men. Clothing and home-use products (产品) are the most popular online.

It was reported that more than 250 billion yuan was spent on online shopping last year, 80% through Taobao.

Taobao means “looking for treasure” in Chinese. People can find almost everything they need on Taobao, from clothes to books, from candies to DVD players.

You may question the security of online shopping, Wang Lin said, “It’s very safe and convenient. Unless you receive the products from the sellers and are satisfied with them, the shop owner will not get the money. You can also get your money back if you want to return the products.”

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
