They say music is universal, and it seems to be true since wherever we go, we see people listening, playing or dancing to it. We tend to think that music is larger than our cultural differences and shows the deeper connections between us.

    But according to a recent study published in the Current Biology, music doesn't speak to everyone. There is a condition, the researchers argue, called "musical anhedonia". They say that those who have this condition may have few abilities to experience pleasure from music.

    For the study, 30 people listened to the same, mostly classical music pieces. They were then asked to complete a questionnaire on how they felt about the music. At the same time, the researchers measured their heart rate and skin reaction, which are considered physiological measures of feelings.

    According to the researchers, most of the people in the study got pleasure from the music. They had a quicker heartbeat and sweatedmore. However, a small number of them had very little and even no pleasant feeling while they were listening to the music. These people had none or very few of the physical signs which the others in the study experienced.

    The researchers say that this means people have different abilities to enjoy music and that "there are people who specifically can't enjoy music at all"

    To study the condition more deeply, another group of scientists, at Columbia University, US, researched brain activities. They found that the key is the blood flow to the reward system in the brain. People who got less pleasure from music had comparatively lower blood flow to areas involved in the reward system of the brain when they were listening to music.

    The lower blood flow makes it more likely that the brain's "reward system" will be inactive. And it will produce less of the "pleasure chemical" dopamine. As a result, people get less pleasure from music.

    If the research is correct, according to National Public Radio, there are simply people who just don't get music. They may get pleasure from many things, but a good tune isn't one of them.

There's nothing better than having a sweet sleep after a full day of tiring work. Like people, animals need to rest after working hard, too. Some animals sleep in water while others dig holes under the ground. Some even sleep high in trees or under the leaves. Although they sleep in different ways, all of them find ways to have a good rest. 

Some animals in the sea sleep in strange ways. For example, fish sleep with their eyes open. They seem to look ahead far into the sea when they take breaks. Sea otters（海獭）sometimes sleep in beds of the plants that grow in the sea. This keeps them from moving away. Parrotfish（鹦嘴鱼）blow something from their mouths when they are ready to sleep. Then a bubble（气泡）will be formed around them. The bubble protects them from danger while they sleep. 

Some animals sleep under the ground. Chipmunks（花栗鼠）sleep curled up（蜷缩）in a ball. Their beds are made of leaves and grass. In winter, they sleep for two weeks and wake up to eat the food. Then they go back to sleep for another two weeks before waking up again. Some desert frogs（青蛙）dig underground holes during the hot and dry season. A frog may stay in its hole for months. 

High above the ground, monkeys find places in trees each evening before they sleep. The tall trees help to keep monkeys safe during the night. Some insects（昆虫）even sleep under the leaves that will be their next meal. A bee may climb down into a flower to rest. When it climbs out the next morning, it rests well and is ready for work.

Cell phones are useful in our {#blank#}1{#/blank#} lives. But you should be careful not to be a noisy phone user. You are supposed to control your own behavior. Here are a few {#blank#}2{#/blank#} .

 When you are in a public place and see a sign that says"Turn {#blank#}3{#/blank#} your cell phone", don't use your phone. If you {#blank#}4{#/blank#} to answer the phone, remember to speak softly for a short time and try to keep away from other people.

 Pay attention! {#blank#}5{#/blank#} on a cell phone while driving is dangerous. According to new traffic rules, drivers who talk on a cell phone while driving will get an offence on their licenses.

Here is some advice on keeping a friendship for a long time. 

First, good communication is a must. We can talk with our friends face to face, or by sending messages. When we are happy or sad, we should tell them our true feelings. That's because they can understand us better. 

Second, say "thanks" often. Little things like a thanks note or a nice present help show how much we like them. 

Third, we must understand each other. Everyone has different ideas and feelings. We should think about our friends' ideas and respect(尊重) those   ▲   . 

Then, we should help each other. When our friends have difficulties, we should listen to their worries carefully and try to help them. You know, a friend in need is a friend in deed!

Finally, meet your friends often. We can do some activities, like having meals or traveling together. Making good memories(回忆) will make our friendship longer. Hope these ways can make our friendship last forever(永远).
