The seahorse is actually not a horse but a fish, and much smaller than any regular horse. In general, a seahorse is about an inch long. It is a beautiful fish that likes warm waters, swims upright (直立的), and looks a little like a chess piece.
Seahorses are an unusual kind of animal because the males (雄性) give birth to babies. Mating (交配) takes place in cooler waters on spring and summer nights with a full moon. The females (雌性) put their eggs into the bodies of the males, and the males give birth to baby seahorses.
The seahorse can use each eye separately, which allows it to search for food without moving the rest of its body. Seahorses situate themselves near deep, fast-running channels rich in plankton, a kind of life on which they feed. They can catch food from an inch and a half away. Seahorses can change from gray or black to yellow or purple within seconds to fit in with their surroundings, and in this way escape from most of their enemies.
One of the surprising facts about seahorses for most people is that they are vertebrates (脊椎动物). They can turn and curl freely, and like to swim in pairs connected by their tails. Their tails are powerful, and they can use them to grasp the surrounding seaweed (海藻) to keep themselves from being swept away. So seahorses are usually found in warm water filled with seaweed.
Now that you know all these facts about seahorses, don’t you find them more interesting?

However, what most parents fail to see is that the best early education they can give their children is usually very cheap.
Parents can see that their children’s skills vary, skilled in some areas while poor in others. What most parents fail to realize, though, is that today’s children lack self-respect and self-confidence.
The problem is that parents are only educating their children on how to take multiple-choice tests and how to study well, but parents are not teaching them the most important skills they need to be confident, happy and clever.
Parents can achieve this by teaching practical skills like cooking, sewing and doing other housework.
Teaching a child to cook will improve many of the skills that he will need later in life. Cooking demands patience and time. It is an enjoyable but difficult experience. A good cook always tries to improve his cooking, so he will learn to work hard and gradually finish his job successfully. His result, a well-cooked dinner, will give him much satisfaction and a lot of self-confidence.
Some old machines, such as a broken radio or TV set that you give your child to play with will make him curious and arouse his interest. He will spend hours looking at them,tying to fix them ,your child might become an engineer when he grows up. These activities are not only teaching a child to read a book, but rather to think, to use his mind. And that is more important.

We don’t want to change your phone, we want to make you say, “Wow, that is a bigger change than I expected”. “iPhone 5” is a result of that desire to surprise.
It’s been completely redesigned. For the first time ever, we’ve increased the size of display (显示) by making the screen taller but not wider.
You can see more of your content without the need to scroll. We are making scrolling the thing of the past. It is more comfortable to use and reduces tiredness from scrolling when you read long documents.
Even with the larger display, it is the thinnest iPhone we ever built. To achieve the design this tall, we have to look at it and completely redesign the architecture inside. It’s 18% thinner and 79.5% taller than the previous iPhone. It makes everything you do on “iPhone5” easier. No more hidden menus, no confusing gestures. Everything is right at your fingertips.
The panorama feature (全景拍照) is simply awesome. The ultra HD (超高清) widescreen display lets you get your entire shot in a single snap (快门). You can also use its creative design for picture stabilization.
With an iPhone this tall, reception of signals has never been better. And of course, all your favorite applications are still available. In fact you will find your old favorites also benefit from the new experiencing handsome ultra HD widescreen. We found while many previous iPhone owners were using Facetime, they only used it for the faces. That’s why we are introducing Bodytime. With its ultra HD widescreen display, Bodytime lets you see a person’s entire body.
It took all of our learning and all of our thinking to realize something so simple, so clear, and yet so tall.
And I wish your pocket were tall enough to hold such a perfect invention!

The breakthrough, which scientists say is the first new way to generate electricity in 160 years, could lead to batteries that use water instead of poisonous substances.
The scientists made the discovery when they were investigating what happens when tap water is forced through extremely narrow glass tubes. Water squeezed down the tubes, each of which was narrower than a tenth the thickness of a human hair, generating a small electric current that ran the length of the tube. To produce a larger electric current, the team tried forcing water through a glass water filter(滤水器)that contained thousands of narrow channels lined up side by side. “When we took a syringe(注射器)of water and squeezed it through the filter, we got enough power to light a light bulb,” said Larry Kostiuk of the University of Alberta in Canada. “The harder you push the syringe, the more electric current you get.”
The current is produced because of an effect in the glass tubes. When they are filled with water, positively charged ions(阳离子)fixed in the tubes are washed away, leaving a slight negative charge on the glass surface. When water is then forced along the tube, the surface repels negatively charged ions in the water while positively charged ions are attracted down the tube. The result is a net flow of positively charged ions that sets up an electric current.
According to Dr Kostiuk, no one has ever thought to use water to produce electricity in this way. “The last time someone came up with a way of generating electricity was Michael Faraday in 1839,” he said. “So this is the first new way of generating electricity in 160 years, which is why we are so excited about it.”
Dr Kostiuk says water batteries might one day be used to power mobile phones and calculators, but admitted that the engineering challenges might make other applications more realistic. “You’d need to be sure it wouldn’t leak, and you’d need to make sure it wouldn’t freeze,” he said.
More likely would be to install the electricity-generating devices where water is already being pumped, such as at city water filtration sites, he said. “It could compete with wind and solar power,” he added.

People in several American states may be surprised to see cars on city streets without a driver. Experimental driverless vehicles now are legal in Florida, Nevada and California. They are pointing the way to a future that is not far down the road. The high-tech company Google has a number of self-driving cars, which had covered 480,000 kilometers by August. Volvo is among the companies doing road tests and says it plans to sell driverless cars by 2020.
In September, California Governor Jerry Brown signed an act to allow autonomous vehicles on the roads of his state. " Today we"re looking at science fiction becoming tomorrow"s reality-the driverless car. " The technology for these cars includes cameras, radar and motion sensors. The systems have been improved through competitions sponsored by the U. S. government agency DARPA. Engineer Richard Mason of the Rand Corporation helped design driverless vehicles for DARPA challenge races.
Cars have become much more fuel-efficient, and new electronic features are" making Hondas safer, said Angie Nucci of Honda America. " A camera on the passenger-side mirror actually engaged on your guiding screen so you can safely change lanes. " Other safety features include warning systems on the front and the sides of the cars. These systems help drivers , but don"t replace them. Curator Leslie Kendall of the Petersen Automotive Museum said autonomous cars will make the high ways safer.
"By taking out drivers, you also remove most risks of an accident," Kendall said. He said consumers, however, may be unwilling to lose control. "It may take them time to come to realize that the technology is indeed reliable, but it will have to prove itself first. "
Mason said the technology already works and the biggest challenge now is getting down the cost for driverless vehicles from hundreds of thousands of dollars to something more affordable. He said this will happen as the technology is improved.

Later, at her new high school, I proudly watch as she continues to rise to the top.Many of her essays are published in newspapers, and her classmates seek her advice when a test is approaching. She never refuses them, and I feel honored to be related to such an intelligent person.
As I walk with her through her journey, I finally come to the point I have been looking forward to most: her life in America. After passing several tests and finding a kind boss to sponsor her, she becomes a college student at University of California, Los Angeles. At first, I sense her loneliness and panic as she tries to adapt to her new surroundings.Though her English is broken and she knows little about American culture, I can tell she is more than grateful to be here. Here she has access to electricity and running water, and most importantly, better schools. At UCLA, she has so many opportunities to grow and advance in her field.
Her journey to America was for just one reason: education.Though having an education will better her life, I know she doesn"t do it for herself.My mom wants her children to have an easier life that will not require hard labor.I see what my mom goes through, and I"m filled with gratitude that she has made the brave choice to move here.
