1 . Twelve-year-old Catherine has a lot of friends—632, actually, if you count up her online friends. And she spends a lot of time with them.
But is it possible that Catherine’s online friendships could be making her lonely? That’s what some experts believe. Connecting online is a great way to stay in touch, they say. However, some experts worry that many kids are so busy connecting online that they might be missing out on true friendships.
Could this be true? During your parents’ childhoods, connecting with friends usually meant spending time with them in the flesh. Kids played Scrabble around a table, not words with friends on their phones. When friends missed each other, they picked up the telephone. Friends might even write letters to each other.
Today, most communication takes place online. A typical teen sends 2,000 texts a month and spends more than 44 hours per week in front of a screen. Much of this time is spent on social media platform.
In fact, in many ways, online communication can make friendships stronger. “There’s definitely a positive influence. Kids can stay in constant contact, which means they can share more of their feelings with each other,” says Katie Davis, co-author of The App Generation.
Other experts, however, warn that too much online communication can get in the way of forming deep friendships. “If we are constantly checking in with our virtual world, we will have little time for our real-world friendships,” says Larry Rosen, a professor at California State University. Rosen also worries that today’s kids might mistake the “friends” on the social media for true friends in life. However, in tough times, you don’t need anyone to like your picture or share your blogs. You need someone who will keep your secrets and hold your hand. You would like to talk face to face.

Friends play a very important part in everyone’s life. Friendship
Some people call you their friends for the wrong reasons. These people are not really friends. They are superficial (表面的) only “friends” on the outside, not the inside where it counts. Superficial friends only want to be your friends if is to their advantage. True friends are there if you are rich or poor.

4 . It is natural for us teenagers to feel upset.
•Move your body.
•Talk about it.
•Laugh a lot.
Humour can rescue you from an upset moment or make you feel better when you’re in an unpleasant mood. No matter what’s going on, the ability to laugh at yourself and your situation is really important.
•Cry — it’s okay!
Sometimes the only way to get out of your feelings is to cry — so go ahead! Shut yourself in your room and cry your eyes out! No one says you have to be happy all the time.
A.Why not pack up your suitcase and take a trip? |
B.We can’t say enough good things about exercise. |
C.But still we should find ways to manage our feelings. |

E.And do you know just smiling can help better your mood? |
F.When you are done, you’ll be ready to face the world again. |
G.Don’t hold in all those feelings until you are ready to explode. |
5 . Blind people have long desired for brightness, but scientists don’t have the technology. To bring that one step closer to reality, Zhiyong Fan, a materials scientist of the Hong Kong University of Science and Technology, developed a new artificial eye recently. The device, which is about as sensitive to light and has sharper vision and a faster reaction time than a real eyeball, may outperform human eyes.
The human eye owes its wide field of view and clear eyesight to the retina (视网膜) — an area at the back of the eyeball covered in light-detecting cells. The design for a new artificial eye is based on the structure of the human eye and uses a friendly light-sensitive material. At the back of the eyeball, an artificial retina is lined with Nan scale light sensors (纳米级光感器). Those sensors measure light that passes through the lens (晶状体) at the front of the eye. Wires attached to the back of the retina send signals from those sensors to the processor, similar to the way nerve networks connect the eyeball to the brain.
“In the future, we can use this to replace damaged human eyes,” says the lead designer. In theory, this artificial eye could see more clearly than the human eye, because the artificial retina contains about 460 million light sensors per square centimeter while a real retina has about 10 million light-detecting cells per square centimeter. Besides, the artificial eyeball records changes in lighting faster than human eyes can — within about 30 to 40 milliseconds, rather than 40 to 150 milliseconds. Although its 100-degree field of view isn’t as broad as the150 degrees a human eye can take in, the device can see as well as the human eye in poor light.
Hongrui Jiang, an electrical engineer at the University of Wisconsin, though, thinks engineers need a much more practical and efficient way to produce vast series of tiny wires on the back of the artificial eyeball to give it superhuman sight, which is super hard to achieve.
