Idioms are phrases and sentences that do not mean exactly what they say. Even if you know the meaning of each word you see or hear, you may not understand the idiom because you don't understand the culture behind it.
For example, if an American boy asks his mother what's for dinner tomorrow, she may say “I'll play it by ear”, that means she doesn't have plans for dinner and she will decide later. "Play by ear" used to mean playing music using the sheet music, but now people often use it when they're not talking about music.
There're many idioms in English. If you learn to use them, your English will be more vivid and colorful. English idioms are more common in spoken English. They can be difficult to remember sometimes. Next time when you hear somebody saying to you, "Give me a hand", you don't necessarily stretch out your hand to him/her, but you do need to be helpful. And when the situation is out of hand, you usually can do very little to manage all that. What about a green hand? It's not about the color of your hand! You're a green hand when you are very new at your work and don't have much experience. If you and your partner always work together hand in glove, you two definitely work together very well.
Can you guess the meanings of some common English idioms to do with parts of your body?

"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!

Have you ever heard an echo of your voice?

An echo is a reflected(反射)sound. Stand in a very large, empty hall with nothing on the walls. Then shout. The sounds you make will hit the walls and come back to you. The walls reflect the sounds. These reflected sounds are called “echoes”.

We can use reflected sound to make sound travel farther. Hold a watch about fifty centimeters from your ear. You cannot hear it. The sound of the watch travels a short way in all directions. It does not travel as far as your ear. You can make it travel to your ear by using a roll of cardboard(纸板筒).

Make the roll of cardboard about fifty centimeters long. Put one end over your ear and hold the watch at the other. Now you can hear the watch because the sound has not gone in all directions. It is reflected down the roll to your ear.

A megaphone(喇叭筒)works in the same way. It makes sound travel farther. It reflects the sound into a beam which can travel a long way. In the ship, the sailor uses the megaphone to make his voice travel. Without the megaphone, his voice cannot travel far.

We use reflected sound in many ways. We use it to measure the depth of the sea, for example. Among the animals, bats and whales use reflected sound to tell them where they are and what things are near them.

d. We make a sound
