Do you forget to turn off the lights and heaters when you go out of a room? In 2040 it will not matter. They will turn themselves off—and on again when you return. You will choose the temperature for each room, the lighting and the humidity. A sensor will find the presence of a human (and, with luck, ignore the dog!) and turn the systems on, and when the humans leave it will turn them off again.
The sensors will work through the central home computer, and they will do much more than just turn the fires and lights on and off for you. They will find faulty electrical appliances, plugs or switches, separate them so that they cannot harm anyone, and then warn you that they need repair. They will detect(发现) fire and if you are out of the house, the computer will call the fire brigade. It will not be too difficult because the locks on the outside doors will be electronic. You will open them using your personal card—the one you use for shopping—maybe using a number known only to you.
It will be impossible to lose the key, and a housebreaker will have to tamper(拨弄) with the lock or with a window. It is not very difficult to make such tampering send a signal to the computer.
The computer will be more than a fireman-policeman-servant. It will be an entertainer, and most of your entertainment will come right into your home. It does now, of course, but by 2040 “entertainment” will mean much more. For one thing, you will be able to take part actively, rather than just watching.

The Peales were a famous family of American artists. Charles Wilson Peale is best remembered for his portraits of leading figures of the American Revolution. He painted portraits of Franklin and Jefferson and over a dozen of George Washington. His lifesize portrait was so realistic that George Washington reportedly once tipped his hat to the figures in the picture.
Charles Wilson Peale gave up painting in his middle age and devoted his life to the Peale museum，which he founded in Philadelphia. The world's first popular museum of art and natural science mainly covered paintings by Peale and his family as well as displays of animals in their natural settings. Peale found the animals himself and found a method to make the exhibits more real. The museum's most popular display was the skeleton (骷髅) of a huge，extinct elephant，which Peale unearthed on a New York farm in 1801.
Three of Peale's seventeen children were also famous artists. Paphaelle Peale often painted still lives of flowers，fruit，and cheese. His brother Rembrandt studied under his father and painted portraits of many famous people，including one of George Washington. Another brother，Rubens Peale，painted mostly landscapes and portraits.

Why do people travel? Well, many people travel because they want to see other countries and visit places that are famous, interesting or beautiful. People also travel to meet new friends, to try new kind of food, to experience life in other parts of the world or simply to get away from cold weather. Yet there are other reasons why people travel. Many of today’s travelers are looking for an unusual experience and adventure travel is becoming more and more popular. Here is a quick look at two popular activities: hiking and rafting.
HIKING
Hiking is a great way to travel. You will get close to nature and take exercise at the same time. Hiking is easy to do and doesn’t have to be very expensive. You can hike close to home or travel to other places. The basic equipment you need for hiking is simple: good shoes, clothes and a backpack. You can hike in the mountains, in a forest or along a river. You can also go for a hike in the city.
Hiking is fun and exciting, but you shouldn’t forget safety. Here are some basic tips for successful hiking: 1. Don’t hike alone. 2. Tell someone where you are going; 3. Bring water and a good map; 4. Watch out for dangers, such as spiders, snakes, or poisonous plants; 5. Wear a hat to protect yourself from the sun; 6.Bring a mobile phone if you have one.
RAFTING
Another exciting adventure is rafting. A raft is a small boat that you can use to paddle down rivers and streams. Rafting is a good way to experience nature. If you want a normal rafting trip, choose a quiet stream or river that is wide and has few trees and other dangers. The name “whitewater” comes from the fact that the water in these streams and rivers looks white when it moves quickly.
As with hiking, you should always think about your safety and wear good clothes. You also need to learn the basic skills of rafting, such as how to handle the raft, how to paddle and how to get in and out of the raft. You should not go rafting unless you know how to swim, and you should always wear a life jacket.Adventure travelers want to _______.

For years I fought with the bird's nest that sat on top of my head-my Medusa（神话中的蛇发女妖） hair．No matter what I did and how hard I tried, in no way could I make my unruly （乱蓬蓬）hair to my satisfaction．
Growing up in a Russian-Jewish home with parents who thought North American styling products were something illegal such as drugs, I was never allowed to put them in :my hair．¨ Why buy hair gel? Your hair is so beautiful naturally," my mother would say．The teens at school did not agree．From boys 'not wanting to kiss me when we played spin the bottle in Grade 7 to being called the mop, I suffered from my hair．
When I got to university, I believed my hair was a wall that stood between me and everything-finding a part-time job, getting a boyfriend, etc．
If only I could find a way to manage the curls and put it behind bars, I told myself, I would feel secure and sexy．I tried everything: rollers, hairspray, gels and, at one point, an iron．Then, in my second year, a miracle happened．I was asked to be a hair model for Japanese hair straightening, a process by which the molecules（分子）of my curls would be broken and reset in a bone-straight position．I was the perfect candidate, the hairdresser told me． Although they said how hair relaxing could damage the :scalp （头皮）,for the next five years I didn't find them to be true． All of the hairdresser's promises were fulfilled: With my hair straight and smooth, I was no longer the¨ mop"．
However, there was extreme damage done to my wallet． To keep up the straightening cost $ 700 every six months, and that was considered cheap．While some people thought I was crazy, I was willing to do anything to never again feel like that anxious, curly-headed girl in Grade 7．But when I moved out． of my parents" house 'at age 26 and rented an apartment, the upkeep of my new image became too costly．
I couldn't hide from my inner Medusa any longer．It was time to hug her and let her fly．Seeking a choice, I turned to the Internet, Google．After hours of searching, I hit upon a“ curly haired" salon, a place designed for girls like me．I doubted these so-called “Curl Ambassadors" could do anything
without using machine of some sort, and though I bought the service called the “Curly-Doo," I suspected I'd have the same unruly mop at the end of the appointment．
I dragged my feet so hard getting there that I arrived 45 minutes late． I secretly hoped they would turn me away．Instead, my stylist simply said :‘‘You are very late． Let me see your hair" At． that moment, my world and beliefs about myself were turned upside down along with my hair． As my head was in a basin full of freezing-cold water, then covered with a jelly-like jam, I wondered what I had got myself into．
¨ Do you really think this will work?" I asked the stylist, Jones．“ My curls are a disaster．"“No curly hair is hopeless," she replied．“They just haven't found a way to work with it, that's all． "
After the hour was over, Jones had completed her work． She had styled my hair using only her hands, water and a mixture of organic jam． I couldn't believe what I was seeing in the mirror: a naturally curly, Medusa-free me．You could argue that hair is just hair． Yet, it is just such physical features that have such a large influence on how we view ourselves．
According to Jones,75 percent of the population have a wave or curl in their hair and don't know what to do with it． Men cut theirs short． Women flat-iron theirs to death． When I read through a beauty magazine or take the subway to work, it makes me sad to see so many people repressing their natural beauty．
Since then, my world has changed． I have always been outgoing, but these days I seem to be more outspoken and confident than ever． On top of that, friends and co-workers tell me I am looking better than ever, but they don't know the source of the change．
