In London's art gallery six or seven men, mostly in their 30s, are busy painting the walls with new designs in colorful lettering and clever tricks. Tins of spray paint and beer stand on the ground. The atmosphere is not unlike that of a golf course: a mix of concentration and relaxation.

    Graffiti(涂鸦) painting is traditionally a daring hobby. Teenagers avoid security guards to put their names on trains and buses. But over the past decade that has almost disappeared from Britain's cities. Between 2007 and 2017 the number of incidents of graffiti recorded by the British Transport Police fell by 63%. A survey by the environment ministry shows that fewer places are damaged by tags(绘名) than ever. Graffiti are increasingly limited to only a few walls. In time the practice may die out entirely.

    The most obvious reason for the decline in tagging and train-painting is better policing, says Keegan Webb, who runs The London Vandal, a graffiti blog (博客). Numerous cameras mean it is harder to get away with painting illegally. And punishments are more severe. A generational change is apparent, too. Now teenagers prefer to play with iPads and video games. Those who do get involved tend to prefer street art to graffiti. And the internet helps painters win far more attention by posting pictures online than they can by breaking into a railway yard.

    Taggers and graffiti artists mostly grew up in the 1980s and 1990s. Those men are now older and less willing to take risks. "We can't run away from the police any more," says Ben Eine, who turned from tagging to street art. The hip-hop culture that inspired graffiti in the first place has faded. Video games and comic books provide more inspiration than music.

    Graffiti may eventually disappear. But for now the hobby is almost respectable. Mr Eine says he has lots of friends who used to paint trains. Now with wives and children, they paint abandoned houses at the weekend. It has become something to do on a Sunday afternoon—a slightly healthier alternative to sitting watching the football.

    Are you interested in country music? I like it very much! It will take me away for a while after I am tired. The guitars and songs will take me to mountains and fields.

    Country music usually talks of everyday life and feelings. It's the spirit of America, easy to understand, slow and simple.

    Country music developed in the Southern United States. It was the folk music of American countryside. Many of songs tell about the lives of farmers. They talk about love, crops or death.

    The life of the countryside can be hard, so the words in country music are often sad. At first, people played the music only at family parties. But it became more popular later. In the 1920s, people played country songs on the radio, and they made them into records.

    When people in the countryside moved to towns and cities to look for work, they took their music with them. Country music continued to change and became popular across America.

    John Denver was one of America's most famous country singers in the 1970s.His song Take Me Home, Country Roads is well­known and people still play it today.

    Two hundred years ago the English poet William Wordsworth wrote "I wander'd Lonely as a Cloud", a poem that expresses a basic spirit of early English Romanticism.

    What makes this poem an example of Romantic thinking? It isn't just that Wordsworth chooses to write about natural scene：it is the way he describes the scene as if it had human emotions. For him, nature is not only a neutral (无感情色彩的) mixture of scenery, colours, plants, rocks, soil, water and air. It is a living force that feels joy and sadness, shares human pain and even tries to educate us human beings by showing us the beauty of life.

    Wordsworth's home, Dove Cottage, is now one of the most popular destinations in the Lake District. You can go on a tour of the garden which William planted with wild flowers and which survived in his backyard even after they disappeared from the area "He always said that if he hadn't been a poet, he would have been a wonderful scenery gardener," says Allan King of the Wordsworth Trust.

    The place near Ullswater, where Wordsworth saw the daffodils(水仙花), is at the southernmost end of the lake. The lake is wide and calm at this turning point. There's a bay where the trees have had their soil eroded(侵蚀)by lake water so that their roots are shockingly exposed. You walk along from tree to tree, hardly daring to breathe, because you are walking in the footprints of William from two centuries ago. The first group of daffodils appear, but they aren't tall yellow trumpets(小号状的花)proudly swinging in the gentle wind. They're tiny wild daffodils, most of them still green and unopened, in groups of six or seven. They're grouped around individual trees rather than collecting together.

    But as you look north, from beside a huge ancient oak, you realize this is what delighted Wordsworth: group after group of the things, spread out to left and right but coming together in your sight so that they form a beautiful, pale-yellow carpet. What you're seeing at last is nature transformed by human sight and imagination.

    My teacher, Mr. August J. Bachmann, was the most influential teacher I ever had.

    I had gotten into trouble in his class: Another student had pushed me for fun, and I became angry and began to hit him. Mr. Bachmann stopped the fight, but instead of sending me to the office, he sat me down and asked a simple question, "Penna, why are you wasting your life？Why aren't you going to college?"

    I didn't know anything about colleges or scholarships. No one had ever considered that a fatherless boy from the poorest neighborhood had a future. That day, instead of rushing off for lunch, he stayed and explained possible education options to me. At the end of our talk, he sent me to see a secretary who had a child at a state college. This was in 1962 at Emerson High School in Union City, New Jersey.

    Well, 55 years have passed, and what have I done with the knowledge he gave me？I gained a PhD from Fordham University when I was only 29.I taught English and social studies and then moved up the chain of command from teacher to principal(校长).

    I've sat on the board for Magnet Schools of America and represented that organization at the United Nations. I've won a number of great educational awards. But where would I be if a truly caring teacher had not taken the time out of his lunch period to speak to me? It was without question only his confidence in me that helped me forward.

    I have repaid his kindness hundreds of times by encouraging misguided youngsters to aim higher. If I have saved any children, it is because of him. If I have been a successful educator, it is because I had a great role model in Mr. Bachmann.

    What's your feeling when you step into senior high school? It is a completely new experience, but you shouldn't worry. We've got some tips to help you.

    You're not alone

    Remember that everybody else in your grade is in the same boat. You may not notice it, but they're just as nervous as you are.

    Moving up to senior high school is a chance, not a problem. Things are different, and all you need to do is to be polite and learn the new rules.

    The teachers will help you

    If you don't know what to do or are worried about something, then ask for help. Teachers are probably the best people to turn to because they have experience in helping new students. Pay attention to what your teachers say.

    Everything changes

    There are lots of differences between junior high school and senior high school. You will you're your lessons with different teachers in different schools. You will have homework for different subjects on different days, so make sure you get organized.

    Other points

    If you've got an elder brother or sister at senior high school, then ask them for advice. Be yourself! It sounds simple, but things will become much better if you just act naturally.

    Going to bed early makes a difference. You'll also find it easier to get up in the morning!

Why does rain seem to make you sleepy?

This spring on the east coast of the US, it feels like we've lost touch with the sun. In Washington, DC, 14 of the first 17 days of May were rainy. {#blank#}1{#/blank#} It means that, for me, May has been one of the months I've felt the sleepiest. The dull weather can hit almost all of our senses in a way that gives a sign to us it is time for a sleep.

First, there's what we see—or rather, what we don't. {#blank#}2{#/blank#} When it's raining and skies are cloudy, we miss out on our body's internal alarm clock. As Naomi, a scientist from Central Queensland University said, when you don't see the sunlight first thing in the morning, your body never gets the signal that it needs to shift into daytime mode.

    {#blank#}3{#/blank#} Plants produce oils during dry periods, possibly to stop seeds from developing. When it rains, the water brings out the oils and they mix with a chemical to create a "musky" smell. {#blank#}4{#/blank#} Additionally, after a thunderstorm there's a chance you may smell ozone(臭氧), which is generated when lightning interacts with the air. Some compare its smell to that of clean bed sheets.

Rain sounds are also comforting. The rhythmic pattern of rain hitting a roof, umbrella, or the ground below is called "pink noise." Pink noise is a category of background noise that has all of the frequencies that human can hear and has lower volumes at higher frequencies. According to some research, it may improve our quality of sleep by decreasing our brain activity.  {#blank#}5{#/blank#}.

The difficulty in waking up, the fresh, earthy scents, and the peace of the rain tapping on windows are enough to make anyone want to go back to bed for the day. Sadly, none of this evidence is enough to justify doing so; but it can at least explain why you may feel a little sleepy on these cloudy days. 

A. Noises can make us feel sleepier during the daytime.

B. The others have been cloudy and dull for at least part of the day.

C. The earthy smell of rain can make you feel calm and comfortable.

D. It makes it easier for us to wake up from our sleep the night before.

E. Sunlight causes our bodies to stop producing what makes us sleepy at night.

F. And you'll also smell that when you are in your garden turning over your soil.

G. You can listen to an hour of rain on a window here, if you intend to test it out.
