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.

My Best Teaching Experience
Tyler was only in my senior class for a semester. He had been suspended (使停学) many times in previous years because of his anger issues. When he entered my class, I thought the worst.
Tyler sat in the back row. Every time I talked to the class, I would ask students questions, calling them by name. Unfortunately, every time I called on Tyler, he would respond with a joke. If he got an answer wrong, he would become angry.
About a month into the year, I was still trying to connect with Tyler. I can usually get students involved in class discussions or at least have them sit quietly and attentively (专心地). By contrast, Tyler was often loud and sometimes rude.
He had been in so much trouble over the years. He expected his teachers to know about his past; about how many times he had been sent to the office or suspended from school. I had found that these sorts of referrals (移交) were not very effective and that students would return from the office behaving worse than before.
One day, Tyler was talking over me while I was teaching. I stopped my lesson and said, “Tyler, why don’t you join in our discussion instead of having one of your own?” With that, he got up from his chair, pushed it over and yelled something. I can’t remember what he said other than that he included some impolite words. I sent Tyler straight to the office, and he received a week’s suspension.
To this point, this was one of my worst teaching experiences. Tyler’s anger was almost too much for me. The week Tyler was suspended from school was a wonderful time, and we got a lot accomplished as a class. However, the suspension week would soon come to an end, and I was fearful of his return.

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.

4 . Smartwatches and fitness trackers (健身追踪器) have gained popularity recently. These tools can record your daily steps, heart rates, etc.
It’s a struggle to overcome the addiction to fitness trackers.
Of course, failing to meet your daily goal can be discouraging. You might focus on your shortcoming rather than your progress. Another problem is that you might find yourself paying too much attention to the step number rather than how your body feels.
Therefore, if you’re spending too much time looking at your smartwatch, limit your daily step count to a comfortable level.
| A．How can you tell whether you’re addicted to your fitness tracker? |
| B．Actually this addiction to step count can be risky, mentally and physically. |
| C．Don’t overuse your smartwatch. |
| D．However, do you find yourself checking your steps and heart rates too often? |
| E．After all, reaching a daily step count can be so appealing. |
| F．Besides, you can find other things to do that don’t involve checking your fitness tracker. |
| G．It doesn’t covey what you’re really feeling. |

6 . Why do we talk the way we do? It might date back to when our ancestors left the jungle for the open plain. Between 5.3 million and 16 million years ago, Africa’s landscapes changed from thick, leafy forests to wide-open grasslands. This environmental change pushed our ancestors out of the trees and onto the ground. Along with all of the physical and behavioral changes this may have caused, researchers also believe it may have changed the way we speak.
“Open landscapes provide us with fewer objects to affect signal communication, meaning our voices can travel further compared with that in thick forests,” Charlotte Gannon, a researcher who studies language development, told Newsweek. “The move to these open spaces may have increased the effectiveness of our communication.”
By comparing the vocal calls of the orangutan (大猩猩) , Gannon and her team were able to establish how different calls could travel across different landscapes. In their study, the team played 487 calls from orangutans and measured their audibility (可听度) at set length over an overall distance of over 1,300 feet in the South African plain.
“Our results were surprising,” Gannon said, “The rule of sound spread suggests that lower-frequency (低频率) sounds (the grumphs) would have traveled further than higher-frequency sounds (the kiss squeaks). Our results actually found the opposite to this.” In these environmental settings, consonant (辅音)-like calls traveled a lot further than vowel (元音) -like calls. Actually, around 80 percent of consonant-based calls were audible at 1,300 feet, compared to only 20 percent of vowel-based calls.
Gannon said these results highlight the importance of studying living orangutan to learn about our species’ history. “We can view them as time machines that allow us to recreate key moments of our history so we can learn more about the development of our language,” Gannon said. “Despite their popularity in modern languages, consonants have often been forgotten when discussing speech development. Our research highlights not only their presence in ancient times but their importance to the development of language.”

7 . Macquarie Island is a tiny island that’s part of Australia. It’s about halfway between New Zealand and Antarctica. The island’s been made a world heritage area because it’s so untouched, but this unique environment is under threat from some unwanted visitors.
It all started when seal hunters came to the island in the early 1800s. They brought rabbits with them as a source of food for the journey, and also on board the ships were rats and mice, which made their way onto the island too. They’re being blamed for destroying the homes of marine birds, causing soil loss and ripping up plant cover, as these before-and-after photos show.
So what’s being done about the problem? It starts with a team of helicopters that fly across the island carrying these giant containers. Inside them are poisoned pellets (有毒饲料) which are dropped and spread across the island. For any rabbits that survived the baiting (诱饵) , there’s a plan B. This special team of dogs is being put through a final training. It’ll be their job to track down any remaining rabbits. They have to also learn to behave around the island’s native wildlife. The dogs could be here for years or until the task is complete. The dogs don’t actually kill the rabbits. They find them, then the hunters decide to either catch the rabbits or shoot them.
But the program has received a bit of criticism. Some people argue 25 million dollars is a lot of money to be spending on wiping out rabbits and rodents (啮齿目动物), and in the process, some native birds will be killed because of the baiting.
The reality is the problem isn’t going to be solved overnight. The people running the program say that even if one pair of rabbits is left alive, the whole task will be seen as a failure, which means these guys could be here for a long time, trying to ensure that this precious island remains protected from pests.
1. Who are these unwanted visitors?| A．Seal hunters. | B．Marine wildlife. | C．Native birds. | D．Foreign species. |
| A．Advancing. | B．Destroying. | C．Dividing | D．Balancing |
| A．Poisoned pellets are being dropped on the island from helicopters. |
| B．A team of hunters is being trained to catch or shoot rabbits. |

| D．A special team of dogs is being sent to kill the rabbits. |
| A．To spend as little money as possible. |
| B．To protect native birds from the unwanted visitors. |
| C．To ensure that no pair of rabbits survive on the island. |

9 . How to Succeed in Science
To succeed in science, you need a lot more than luck. In my view, you have to combine intelligence with a willingness not to follow conventions(常规) when they block your forward path. Thus, these have come to be my rules for success.
That might sound proud, but the fact is that you must always turn to people who are brighter than you. It’s like playing any game. Even as a child, I never wanted to play games with anyone who was as bad as I was. If you win, it gives you no pleasure. And in the game of science or life, the highest goal isn’t simply to win; it’s to win at something really difficult.
Take risks.
To make a huge success, a scientist has to be prepared to get into deep trouble. If you are going to make a huge jump in science, you will very likely be unqualified to succeed by definition.
Never do anything that bores you.
My experience in science is that someone is always telling you to do things, and then leaves you alone. I’m not good enough to do well in something I dislike.
It’s very hard to succeed if you don’t want to be with other scientists, because you have to go to key meetings where you spot key facts that would have escaped you. And you have to chat with your competitors, even if you find them objectionable.
So my final rule is:
| A．Avoid foolish people. |
| B．Meet challenges with great courage. |
| C．If you can’t stand being with your real peers, get out of science. |
| D．Put it another way, it’s to go somewhere beyond your ability and come out on top. |
| E．Make sure you always have someone to save you from a deep mess. |
| F．In fact, I find it hard to do well in something I like. |
| G．Besides, you even have to be prepared to disbelieve your scientific heroes. |
An Unforgivable Mistake
A few years ago, the company I work for sent my wife and me to live in New York for a year. I’ve always loved jogging, so I was really happy when I found the apartment they had rented for us was next to Central Park. This meant that every morning I could go for a run before I went to work.
Because a lot of people had told me to be careful of muggers (行凶抢劫者) in the park, I didn’t usually take anything with me. How could they rob me if I didn’t have anything? But one morning my wife asked me to buy some bread on the way home, so I put a $10 bill in my back pocket.
It was a beautiful morning and the park was quiet with very few people walking or jogging around. While I was running, another jogger bumped (撞) into me. He apologized and continued running. For a while, I didn’t think too much of it. However, when I noticed the wide path where I was running, I thought it was kind of strange. The warning of muggers in the park occurred to me. It could have been a mugger! I suddenly became alarmed, so I checked my pocket. The money was missing! I immediately started to run after the jogger. I finally caught up with and grabbed him firmly by the arm. I started shouting and demanding that he give me the $10 bill. I’m not usually a hot-headed person, but I really lost my temper at that moment. I couldn’t believe the robbery was actually happening to me. Filled with anger, I shook my fist at him. This seemed to frighten him. He quickly put his hand in his pocket and gave me the money. Then he ran away as fast as he could.
I bought the bread and went home. As soon as I got home, I couldn’t wait to tell my wife the story. “You won’t believe what happened to me,” I started with pride. She immediately interrupted (插话), “I know, you left the money for the bread on the kitchen table.”
