Hello. I'm Jan from Mrs. Lake's class. My class wants to work together to help the public. We think we have found a great way to do this. Last month we did a class project on the highways near our town. We learned about the Adopt-a-Highway Program. This program brings people together to pick up litter along the roads. We think it would be a great idea for all students in our school to join the program and adopt（收养） a highway.

    Adopting a highway is not like adopting a pet. When a highway is adopted, only part of the highway is cared for by a group of people. The group agrees to work every week to keep its part of the highway clean. Each group gets its own sign that has the name of the group printed on it. The sign is put up at the side of the road . This sign lets drivers know who is keeping that area of the road clean.

The Adopt-a-Highway Program is a great way for people to help their environment look nicer. Also, the government does not have to send out as many road workers. This saves money. Finally, people may try harder to keep roads clean if they see people, especially teenagers like us, cleaning them up.

     We will need helpers to care for our adopted highway. If you want to feel great and keep our roads clean，please come with your parents to the meeting next week. We will meet in Mrs. Lake's room on Wednesday at 6:00 P.M. At the meeting, we will talk about which roads are the dirtiest as a result of people's unkind acts. Then we'll try to pick an area to adopt and clean.

    I look forward to seeing you at the meeting. Remember to keep our roads clean!

    The Kentucky Derby is a horse race held annually in Louisville, Kentucky, United States on the first Saturday in May. Here are some helpful suggestions for your first trip to the Kentucky Derby!

Fashion vs. Comfort

    In many ways, the Kentucky Derby is the world's largest and most entertaining fashion show, with impressive hats and clothes! You'll be on your feet and walking a lot, so pack a pair of comfortable shoes to change into during the day.

Your Tickets

    You MUST have your tickets in order to get through the gates. Please note that the only place that has official permission to buy and resell Kentucky Derby tickets is the Kentucky Derby Ticket Exchange. Law enforcement officials will be on site to prevent people from selling tickets at a much higher price.

    If you have questions about your tickets in advance of the Derby, please call Churchill Downs customer service at 502-636-4400.

Finding Help

    With over 14,000 employees throughout the track on Derby day, you aren't too far from someone who can help. If you can't find an employee to help you, please text the word HORSE to 69050 and you will be placed in touch with Guest Services.

Safety & Security

    For the safety of all our guests, your bag may be searched by security. A number of items are forbidden from entering the facility(场所).

    For security and crowd control reasons, you can't enter the facility again after you get out. This means that you will not be able to go outside the gates to fetch items from your car once you have passed through security. Please be sure to bring everything you need.

    Macao is only forty miles from Hong Kong and it is easy to reach. You can get there by sea. It is an interesting place and it has a long history. Macao is part of China and most people living there are Chinese.

    The first Europeans in Macao came from Portugal. More than four hundred years ago the Portuguese went there to trade with China. Some settled and made their homes there. They built strong forts（要塞）to guard the city and the harbor. They also built churches, schools, hospitals and other places. Slowly the city grew. People from many other countries came to live and work in Macao.

    Today many people live in Macao. Some only go there to watch dog-racing or motor-racing or to gamble（赌博）with their money. But Macao is a quiet and peaceful place. It is pleasant just to walk around and look at the old buildings and forts. You feel you are back in the old days. Of course，some of the buildings are now in ruins. The Church of St. Paul has only the front wall with many steps leading up to it. But it is still interesting to see.

    When you are hot and tired, there are small cool gardens to rest in. When you are hungry, there are good restaurants with many kinds of food. Nearby are some islands, which are also nice to visit and are easy to get in. There are certainly a lot to see and to do in Macao.

Recordings of angry bees are enough to send big, tough African elephants running away, a new study says. Beehives (蜂窝)—either recorded or real—may even prevent elephants from damaging farmer's crops.

    In 2002, scientist Lucy King and her team found that elephants avoid certain trees with bees living in them. Today, Lucy wants to see if African honeybees might discourage elephants from eating crops. But before she asked farmer to go to the trouble of setting up beehives on their farms, she needed to find out if the bees would scare elephants away.

    Lucy found a wild beehive inside a tree in northern Kenya and set up a recorder. Then she threw a stone into the beehive, which burst into life. Lucy and her assistant hid in their car until the angry bees had calmed down. Next，Lucy searched out elephant families in Samburu National Reserve in northern Kenya and put a speaker in a tree close to each family.

    From a distance, Lucy switched on the pre-recorded sound of angry bees while at the same time recording the elephants with a video camera. Half the elephant groups left the area within ten seconds. Out of a total of 17 groups, only one group ignored the sound of the angry bees. Lucy reported that all the young elephants immediately ran to their mothers to hide under them. When Lucy played the sound of a waterfall (瀑布) instead of the angry bees to many of the same elephant families, the animals were undisturbed. Even after four minutes, most of the groups stayed in one place.

Lucy is now studying whether the elephants will continue to avoid the sound of angry bees after hearing it several times. She hasn't tested enough groups yet to know, but her initial (最初的) results were promising enough to begin trials with farmers. She has now begun placing speakers in the fields to see if elephants are frightened away.

    Today's post is almost about signs in English. You will see signs on the road while driving or when walking down a street. Now let's take a closer look at the signs in the picture below, so you can fully understand what they mean in case you come across one of them.

    Starting with the top row, we have a:

    Yield sign—This sign indicates (标示) that you need to slow down ,but you may not have to come to a full stop.

    Crosswalk—This is a sign that indicates people have the right of way to cross the street, so cars have to stop when they see a person waiting next to one of these signs.

    Second row:

    Do not enter—This sign indicates you are not allowed to enter a road at that point.

    Buckle up(系好安全带)!— There are often signs on roads in the United States reminding people that wearing seat belts(安全带) is mandatory (强制的) (seat belt laws differ depending on what state you are in ,but all US states have seat belt laws).

    Third row:

    Be alert (警惕的) for bears—This is another sign that is used to indicate to drivers and pedestrians (行人) that they should be alert for wildlife in the area.

Playground—This is the sign used to alert drivers that there is a playground nearby, so it is a good idea to slow down and watch for children.

    Before the 1830s, most newspapers were sold through annual subscriptions in America, usually $8 to $10 a year. Today $8 or $10 seems a small amount of money, but at that time these amounts were forbidding to most citizens. Accordingly, newspapers were read almost only by rich people in politics or the trades. In addition, most newspapers had little in them that would appeal to a mass audience. They were dull and visually forbidding. But the revolution that was taking place in the 1830s would change all that.

    The trend, then, was toward the "penny paper"-a term referring to papers made widely available to the public. It meant any inexpensive newspaper; perhaps more importantly it meant newspapers that could be bought in single copies on the street.

    This development did not take place overnight. It had been possible(but not easy)to buy single copies of newspapers before 1830,but this usually meant the reader had to go down to the printer's office to purchase a copy. Street sales were almost unknown. However, within a few years, street sales of newspapers would be commonplace in eastern cities. At first the price of single copies was seldom a penny-usually two or three cents was charged-and some of the older well-known papers charged five or six cents. But the phrase "penny paper" caught the public's fancy, and soon there would be papers that did indeed sell for only a penny.

    This new trend of newspapers for "the man on the street" did not begin well. Some of the early ventures(企业)were immediate failures. Publishers already in business, people who were owners of successful papers, had little desire to change the tradition. It took a few youthful and daring businessmen to get the ball rolling.
