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.

So why has English changed over time? All languages change and develop when cultures meet. At first the English spoken in England between about AD 450 and 1150 was very different from the English spoken today. It was based more on German than the English we speak at present. Then between about AD 800 and 1150, English became less like German because those who ruled England spoke first Danish and later French. These new settlers improved the English language and especially its vocabulary. So by the 1600’s Shakespeare was able to make use of a wider vocabulary than ever before.
Finally by the 19th century the language was settled. At that time two big changes in English spelling happened: first Samuel Johnson wrote his dictionary and later Noah Webster wrote The American Dictionary of the English Language. The latter gave a separate identity to American English spelling.
English now is also spoken as a foreign or second language in South Asia. For example, India has a very large number of fluent English speakers because Britain ruled India from 1765 to 1947. During that time English became the language for government and education. Today the number of people learning English in China is increasing rapidly.

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.

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.”
