Coffee drink is widespread. When people argue about whether coffee is good for health, they're usually thinking of the health of the coffee drinker. Is it good for your heart? Does it increase blood pressure? Does it help you concentrate? However, coffee affects the health of the human population in other ways, too.

    Traditionally, coffee bushes were planted under the shade of taller trees. However, more and more farmers in Latin America are deforesting the land to grow full sun coffees. At first, this increases production because more coffee bushes can be planted if there aren't any trees. With increased production come increased profits.

    Unfortunately, deforesting for coffee production immediately decreases the local wildlife habitat, because native birds nest and hide from predators（捕食者）in the tall trees and migrating birds rest there.

    Furthermore, in the long term, the full-sun method also damages the ecosystem because more chemical fertilizers and pesticides（杀虫剂）are needed to grow the coffee. The fertilizers and pesticides kill insects that eat coffee plant, and then the birds eat the poisoned insects and also die. The chemicals kill or sicken other animals as well, and can even enter the water that people will eventually drink.

    Fortunately, farmers in Central and South America are beginning to grow more coffee bushes in the shade. We can support these farmers by buying coffee with such labels as "shade-grown" and "bird-friendly".

    Sure, these varieties might cost a little more. But we're paying for the health of the birds, the land, ourselves, and the planet. I think it's worth it.

    Your house may have an effect on your figure. Experts say the way you design your home could play a role in whether you pack on the pounds or keep them off. You can make your environment work for you instead of against you. Here are some ways to turn your home into part of your diet plan.

    Open the curtains and turn up the lights. Dark environments are more likely to encourage overeating, for people are often less self-conscious(难为情) when they're in poorly lit places — and so more likely to eat lots of food. If your home doesn't have enough window light, get more lamps and flood the place with brightness.

    Mind the colors. Research suggests warm colors fuel our appetites. In one study, people who ate meals in a blue room consumed 33 percent less than those in a yellow or red room. Warm colors like yellow make food appear more appetizing, while cold colors make us less hungry. So when it's time to repaint, go blue.

    Don't forget the clock — or the radio. People who eat slowly tend to consume about 70 fewer calories(卡路里) per meal than those who rush through their meals. Begin keeping track of the time, and try to make dinner last at 30 minutes. And while you're at it, actually sit down to eat. If you need some help slowing down, turning on relaxing music. It makes you less likely to rush through a meal.

    Downsize the dishes. Big serving bowls and plants can easily makes us fat. We eat about 22 percent more when using a 12-inch plate instead of a 10-inch plate. When we choose a large spoon over a smaller one, total intake(摄入) jumps by 14 percent. And we'll pour about 30 percent more liquid into a short, wide glass than a tall, skinny glass.

    Whenever we talk about holidays, my mother teases my sister and me about how we “make out like robbers.” She is referring to the fact that we are half Jewish and half Indian, so we receive gifts on both the festivals of lights: Hanukkah and Diwali. Though my mother teases us, I do not mind getting two sets of gifts!

    Hanukkah is celebrated on the 25^th day of the Jewish month, which is usually sometime in December. On Hanukkah, like most Jewish families, we light a menorah and say a prayer each night. We also say a special prayer on the first night. After that, it is a tradition for my sister and me to do 'hot and cold' for our hidden Hanukkah gifts. When we walk towards the gift, our parents say 'hot' and when we walk further away, they say 'cold'. We each receive one present every night of Hanukkah. Another part I like about this holiday is seeing family members who we do not see often. My aunt usually stays for a few days, and we sometimes visit other relatives.

    Diwali is celebrated on the 13^th day of the dark fortnight of the month of Ashwin (October/November). To celebrate Diwali, my family does a pooja, or prayers, in honor of the goddess Lakshmi. Since she is the goddess of wealth and prosperity, the pooja includes washing silver coins in milk and water. In India, people decorate their houses with lamps, similar to the way you might light up your house for Christmas. My family just places a few candles outside. We also set off firecrackers, which is my favorite part. We often do this activity with friends to add to the excitement.

    Both holidays have different histories and stories. We celebrate them in different ways, yet they both have the same meaning. They both translate into Festival of Lights, and they both mean family and presents for me!

    The following is a timetable in Guangzhou Baiyun International Airport.

    My favourite book is The Adventure of Tom Sawyer by Mark Twain. Tom lives with his aunt Polly in a quiet street of St. Petersburg, Missouri. He's a lively and clever young boy, and he finds himself in many exciting adventures. He runs away with his two friends, Huck Finn and Joe, to an island in the middle of the Mississippi River for several days. With Huck he goes looking for treasure, with Becky he gets lost in a cave. And finally, they find a box of gold.

    My favourite scene in the book is when everyone thinks Tom is dead. He decides to go to his own funeral. He hides and watches for a time and then suddenly he appears. Everyone is astonished to see him but they're also pleased to see him alive.

    Tom is the hero of the story, but there are other important characters. Huck is an outsider and everyone is afraid of him. Becky is pretty with fair hair, Joe is Tom's best friend. And Injun Joe is the bad man of the story.

    The theme of the story is about children growing up. It describes how strangers are seen in small towns of America. Finally, it talks about freedom, social rules and how people are punished for bad behaviour.

    Why do I think The Adventure of Tom Sawyer is a great book? Mark Twain wrote the story in 1876, but it's still read and loved by people all over the world today. And although it's only a story, Twain wrote it in the everyday English of the southern states of America in the 19th century, so it sounds very real. Today it's thought to be one of the greatest books in American literature. Go on—read it! I know you'll enjoy it, too.

    What is your favorite color? Do you like yellow, orange, red? If you do, you must be an optimist, a leader, an active person who enjoys life, people and excitement. Do you prefer graysand blues? Then you are probably quiet, shy and you would rather follow than lead. If you love green, you are strong-minded and determined. You wish to succeed and want other people to see you are successful. At least this is what psychologists tell us, and they should know, because they have been seriously studying the meaning of color preference, and the effect that colors have on human beings. They tell us that we don't choose our favorite color as we grow up. If you happen to love brown, you did so as soon as you opened your eyes, or at least as soon as you could see clearly.

    A yellow room makes us feel more cheerful and comfortable than a dark green one, and a red dress rings warmth and cheer to the saddest winter day. On the other hand, black is depressing. Light and bright colors make people not only happier but also more active. It is a fact that factory workers work better, harder, and have fewer accidents when their machines are painted orange rather than black or dark grey.

    Remember, then, that if you feel low, you can always brighten your day or your life with a new shirt or a few colorful things. Remember also that you will know your friends and your enemies better when you find out what colors they like and dislike. And don't forget that anyone can guess a lot about your character when you choose a piece of handkerchief.
