In ancient times, man settled near rivers or on river banks and built up large empires.
Water is nature’s most valuable gift to man. Man needs water to irrigate his crops, to cook and to wash. In nations all over the world, rivers mean life and wealth. They feed and clothe nations around them.
Water is also a source of energy and power. Man builds huge dams across the rivers to control the water for irrigation and get the energy needed to drive generators. The electrical power is then directed to homes, cities, factories and television stations.
Man uses water each day. In a small way rivers help to keep man in good health and provide for his amusements. Various forms of water sports keep man strong and healthy.

At US $349, the Apple Watch is expensive
If the Apple Watch becomes popular, it will change the way the world communicates with computers. “It might not only be a change for Apple, but for the whole industry,” says technology expert, Daniel Ives.
How does it work?
The Apple Watch has a speaker that users can both hear and feel. You can press the side button to communicate with people quickly and easily. The Apple Watch also introduces health and fitness apps(应用程序)that can help people lead healthier lives.
You can try it.
According to Matt Vella, a writer for TIME magazine, the watch is “the most thrilling product since the iPad.”
After actually trying the watch, he says: “ There’s a lot we don’t know about the Apple Watch. How long will its battery last? How exactly will it connect with the iPhone? But wearing the watch answers some other questions. It is very comfortable. You can easily forget you are wearing the Apple Watch.”

“Examine the extended family, and you’ll probably find a bossy grandparent, aunt, uncle or cousin in every generation. It’s an inheritable trait.” says Russell Barkley, a professor at the Medical University of South Carolina. Other children who may not be particularly bossy can gradually gain dominance(支配地位)when they sense their parents are weak, hesitant, or in disagreement with each other.
Whether it’s inborn nature or developed character at work, too much control in the hands of the young isn’t healthy for children or the family. Fear is at the root of a lot of bossy behavior, says family psychologist John Taylor. Children, he says in his book From Defiance to Cooperation, “have secret feelings of weakness” and “a desire to feel safe.” It’s the parents’ role to provide that protection.
When a “boss child” doesn’t learn limits at home, the stage is set for a host of troubles outside the family. The overly willful and unbending child may have trouble obeying teachers or coaches, for example, or trouble keeping friends. It can be pretty lonely as the top dog if no one likes your bossy ways.
“I see more and more parents giving up their power,” says Barkley, who has studied bossy behavior for more than 30 years. “They bend too far because they don’t want to be as strict as their own parents were. But they also fell less confident about their parenting skills. Their kids, in turn, feel more anxious.”

In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, researchers will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the researchers will review the data to determine if it has inspired any changes in the life of its owner.
“I talk to him all the time, and he responds to my voice,” says a seventy-year-old lady, “When I’m watching TV, he’ll stay in my arms until he wants down. He has a mind of his own.”
The AIBOs respond to certain orders. The researchers say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog removes exercise and feeding concerns.
“At the beginning, it was believed that no one would relate to the robotic dog, because it was metal and not furry.” Beck says, “But it’s amazing how quickly we have given up that belief.”
“Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters’ blood pressure, oxygen levels, or heart rhythms. AIBOs may even one day have games that can help stimulate older people’s minds.”

5 . New restaurants, galleries, temples and new architecture…These places are homes for people like us who live and work there. How would you want visitors to behave in your own home? Think about it.
Do your homework
Help preserve the sites. Most of the sites you visit may be visited by millions of people a year, so care needs to be taken to allow others to enjoy them as well. Some of these monuments are so old and fragile that they are sensitive to the touch of hands or bags and shows.
And here’s the big one—good manners are nearly universal.
A.Experience the place. |
B.Always have a cloth bag with you . |
C.Read up on the places you want to visit. |
D.Try to buy something from the local stores. |
E.A good tourist is polite, positive and eco-sensitive. |
F.We’ve cleaned up after ourselves and taken only good memories. |
G.If we are good tourists, wherever we go, we try to make it a little better because of our visit. |
Professor Reilly’s team studied over 1600 children from Melbourne, Australia. Their mothers had been filling out regular questionnaires since their babies were eight months old and the children were judged by a range of language and behaviour tests when they reached the age of four. Reilly and her colleagues asked the parents to call the study group if their children started showing signs of stuttering. Diagnoses were confirmed by a researcher, who then visited the homes of children with a stutter every month to check on their progress.
By the age of four, 181 of the children studied had been diagnosed with a stutter. Follow-up visits to the 181 children who were judged after diagnoses showed just nine no longer had a stutter one year later. Stuttering children scored 5. 5 points higher than that of their non-stuttering children on language tests and 2. 6 points higher on the test of non-verbal intelligence. The researchers said it was possible that stuttering could improve language skills, or that stuttering could result from very fast language development among some children.
The research suggests parents of children who stutter are usually advised to wait a year before looking for treatment —which can be expensive — to see if the stutter goes away by itself, unless the children become very unhappy or stop talking.
