1 . If you were bringing friends home to visit, you could show them the way. You know the landmarks—a big red house or a bus-stop sign. But what if you were swimming in the middle of the Atlantic Ocean? Could you still find your way home? A loggerhead turtle（海 龟）could.
According to Dr. Ken Lohmann, loggerheads have a magnetic（磁力的）sense based on Earth’s magnetic field. It helps them locate the best spots for finding food and their home beaches.
Scientists already know that several other animals, such as whales and honeybees, can detect（探测到）magnetic fields. The difference between them and loggerheads, however, is the way they learn to use their magnetic sense. Young whales and honeybees can learn from adults. Loggerheads are abandoned as eggs.
As newborn loggerheads have no adults to learn from, what helps them figure out how to use their magnetic sense? Lohmann thinks one of the cues was light on the sea.
Baby loggerheads hatch only at night. However, a small amount of light reflects off the ocean. The light makes that region brighter. Heading toward the light helps them get quickly out to sea, where they can find food. Lohmann tested whether newborn loggerheads use this light source to set their magnetic “compasses”（罗盘）. He and his team put some newborns in a water tank and recorded which way they swam. Around the tank, the scientists created a magnetic field that matched the Earth’s. They set a weak light to the east of the magnetic field. Then they let the newborns go.
At first, the newborns swam toward the light. After the scientists turned off the light, the turtles that had seen the light in the east always swam toward east. When the researchers reversed（颠倒）the magnetic field, these turtles turned around and swam toward the new “east”.
This and the follow-up experiments all showed that loggerheads use light from the outside world to set their magnetic “compasses” and then remember the “correct” direction. If a turtle hatches on a brightly-lit beach, that would damage its magnetic sense forever and make survival hard for the turtle.
Lohmann’s work has led others to protect the habitat of this endangered species. Yet many questions about these creatures remain unanswered, and researchers have a lot to study.

2 . A shocking 53.6 million tons of electronic waste were discarded（丢弃）last year, a new UN-backed report has revealed. The report shows that e-waste is up 21%from five years ago. This isn't surprising, considering how many more people are adopting new technology and updating devices regularly to have the latest versions, but the report also shows that national collection and recycling strategies are nowhere close to matching consumption rates.
E-waste contains materials including copper（铜）, iron, gold and silver, which the report gives a conservative value of $ 57 billion. But most are thrown away or burned rather than being collected for recycling. Precious metals in waste are estimated to be worth $ 14 billion, but only $4 billion-worth is recovered at the moment.
While the number of countries with national e-waste policies has grown from 61 to 78 since 2014, there is little encouragement to obey and a mere 17% of collected items are recycled. If recycling does occur, it's often under dangerous conditions, such as burning circuit boards to recover copper, which "releases highly poisonous metals" and harms the health of workers.
The report found that Asia has the highest amounts of waste overall, producing 24.9 million metric tons (MMT), followed by Europe at 12 MMT, Africa at 2.9 MMT, and Oceania at 0.7 MMT.
But whose responsibility is it? Are governments in charge of setting up collection and recycling points, or should companies be responsible for recycling the goods they produce? It goes both ways. Companies do need to be held accountable by government regulations and have incentives to design products that are easily repaired. At the same time, governments need to make it easy for citizens to access collection points and deal with their broken electronics in a convenient way. Otherwise, they may turn to the easiest option-the landfill.

3 . There are around 400,000 students in London. As university can be a costly time, many of these students will want to look for part-time work. Here are 4 relatively easy jobs to bag yourself in London and ensure a bit of pocket money through your university experience.
Waitressing
It is not hard to find waitressing jobs since London has an abundance of pubs and eateries. Gumtree and Indeed are good places for such opportunities. Hospitality UK and Next door are other great websites. However, as many of these positions are advertised on the windows of restaurants and pubs, going inside and asking the staff there about the positions is a much better idea. This will also demonstrate you as active and confident. Rates are around £12--15 an hour.
Mystery (神秘)shopping
It may not have you laughing to the bank but it's extra pocket money. You go at any time as a regular customer and check out the services that the business provides. You report back to the client and they will pay for your purchases alongside £5 —10.
Care Assistant
For those who have a heart of gold and want to help, caring is the way. There's a huge demand for people to spend your free time with elderly people or help people with disabilities. It can be cooking meals or making sure they're taking their medicine on time.
Receptionist
If you're a good communicator and can act professionally, a receptionist might be a great opportunity for you, which will help you build administrative skills and experience. Receptionist jobs are available at doctors surgeries, dentists, gyms, large offices and more.
1. Which is the preferable way to land a waitressing job?| A．Referring to Gumtree. | B．Surfing Next door. |
| C．Inquiring about positions in person, | D．Contacting advertisement company. |
| A．Amusing bank staff. | B．Working at fixed times. |
| C．Making purchases for clients, | D．Feeding back service quality. |
| A．Waitressing. | B．Mystery shopping. |
| C．Care Assistant. | D．Receptionist. |
4 . Recycling Electronic Waste
When Alex Lin was 11 years old, he read an alarming article in the newspaper which said that people were burying old computers in backyards, throwing TVs into streams, and dumping (丢弃) cell phones in the garbage. This was dangerous because e-waste contains harmful chemicals that can leak into the environment, getting into crops, animals, water supplies—and people.
Alex was really worried and decided to make it next project for WIN—the Westerly Innovations Network. Alex and six of his friends had formed this organization to help solve community problems two years before.
But what could they do about this project with e-waste? The team spent several weeks gathering information about the harmful chemicals in e-waste and their effects on humans. They learned how to dispose (处置) of e-waste properly and how it could be recycled. Then, they sent out a survey and found only one in eight knew what e-waste was, let alone how to properly dispose of it.
Alex and his friends went into action. They advertised in the local newspaper and distributed notices to students, asking residents to bring their unwanted electronics to the school parking lot. The drive lasted two days, and they collected over 9, 500 kilograms of e-waste.
The next step was to set up a long-term e-waste drop-off center for the town. After some research, they’d learned that reusing is the best way to deal with electronic devices and it is seven times more efficient than recycling. So, they began learning to refurbish (翻新) computers themselves and distributed them to students who didn’t have their own. In this way, they could help students in the area and protect the environment at the same time.
For a lasting solution to e-waste, the drop-off center wasn’t enough. Laws would have to be passed. In 2016, WIN helped push for an e-waste bill in their town, which required companies that manufactured or sold electronics to take back e-waste. The bill clearly forbids the dumping of e-waste.
Because of the work of WIN, more and more people, like Alex and his team, are getting the message about safe disposal of e-waste. As Alex says, “Today’s technology should not become tomorrow’s harmful garbage.”
1. What was Alex’s worry after he read the article?| A．The littering of e-waste. | B．The recycling of plastic. |
| C．The change of environment. | D．The overuse of old computers. |
| A．Set up WIN. | B．Collect information. |
| C．Ask friends for help. | D．Carry out a survey. |
| A．Traditional. | B．Competitive. |
| C．Scientific. | D．Convenient. |
| A．There is no end to perfection. |
| B．Success comes through failure. |
| C．Every positive attitude has a reward. |
| D．Young people can make a big difference. |

6 . With a satisfied smile, Keisha finished the last sentence of her English essay about one of her heroes, Rosa Parks, an important figure in the Civil Rights Movement.
“Keisha,” her mother shouted from downstairs. “It’s almost 4:15.”
“Don’t worry. I won’t be late. ” Keisha pulled down a storybook from her bookshelf， as she always read to the nursing home’s residents. And on an impulse（一时心血来潮）, she added her English notebook as well.
As Keisha came running in the door, the manager told her, “We have a new resident this week, Mrs. Ruby Watson. She’s still adjusting to her new surroundings. You’ll find her in Room 28. And by the way, Keisha, good luck.”
Keisha walked down the hallway at a quick pace. As she entered Room 28, she met two sharp brown eyes staring at her doubtfully.
“I’m Keisha Jackson, a volunteer,” Keisha explained. “I come here to help pass the time with residents, or read to them, or, . . .” Keisha started stammering（结巴）as Mrs.
Watson continued to stare at her.
“I didn’t request anyone to keep me company,” Mrs. Watson interrupted. “I’m alone most of the time, and that’s how I prefer it.”
“I brought along some funny stories,” Keisha said hesitantly.
“I’m not in the mood for funny stories,” Mrs. Watson replied angrily. “What else do you have?”
Nervously, Keisha opened her notebook to her essay. She read the title aloud, “Rosa
Parks: A Woman of Courage and Conviction（信念）.” She glanced at Mrs. Watson to see how she might react, but to her surprise, Mrs. Watson’s face relaxed and her eyes shone.
“Read to me about Rosa,” Mrs. Watson said.
Keisha read how Rosa Parks’ refusal to give up her seat to a white passenger on a bus in 1955 inspired the protest that became a turning point in the struggle for civil rights.
“I walked with Rosa Parks and Dr. Martin Luther King,” Mrs. Watson said with pride. “That was the greatest moment of my life because…” She paused.
“Because… you were a woman of courage and conviction too.”
Sitting up straighter, Mrs. Watson said, “Yes, I was and I still am. Thank you for reminding me, Keisha. Next Thursday, I will tell you my story.”

7 . In a recent series of experiments at the University of California, researchers studied toddlers’ thinking about winners and losers, bullies (欺凌) and victims.
In the first experiment, toddlers (学步儿童) watched a scene in which two puppets (木偶) had conflicting goals: One was crossing a stage from right to left, and the other from left to right. The puppets met in the middle and stopped. Eventually one puppet bowed down and moved aside, letting the other one pass by. Then researchers asked the toddlers which puppet they liked. The result: 20 out of 23 toddlers picked the higher-status puppet — the one that did not bow or move aside. It seems that individuals can gain status for being dominant (占优势的) and toddlers like winners better than losers.
But then researchers had another question: Do toddlers like winners no matter how they win? So, researchers did another experiment very similar to the one described above. But this time, the conflict ended because one puppet knocked the other down and out of the way. Now when the toddlers were asked who they liked, the results were different: Only 4 out of 23 children liked the winner.
These data suggest that children already love a winner by the age of 21-31 months. This does not necessarily mean that the preference is inborn: 21 months is enough time to learn a lot of things. But if a preference for winners is something we learn, we appear to learn it quite early.
Even more interesting, the preference for winners is not absolute. Children in our study did not like a winner who knocked a competitor down. This suggests that already by the age of 21-31 months, children’s liking for winners is balanced with other social concerns, including perhaps a general preference for nice or helpful people over aggressive ones.
In a time when the news is full of stories of public figures who celebrate winning at all costs, these results give us much confidence. Humans understand dominance, but we also expect strong individuals to guide, protect and help others. This feels like good news.

8 . Terrafugia Inc. said Monday that its new flying car has completed its first flight, bringing the company closer to its goal of selling the flying car within the next year. The vehicle—named the Transition—has two seats, four wheels and wings that fold up so it can be driven like a car. The Transition, which flew at 1,400 feet for eight minutes last month, can reach around 70 miles per hour on the road and 115 in the flies using a 23-gallon tank of gas and bums 5 gallons per hour in the air. On the ground, it gets 35 miles per gallon.
What is the first paragraph mainly about?
| A．The basic data of the Transition. | B．The advantages of flying cars. |
| C．The potential market for flying cars. | D．The designers of the Transition. |
9 . To learn to think is to learn to question. Those who don't question never truly think for themselves. These are simple rules that have governed the advancement of science and human thought since the beginning of time. Advancements are made when thinkers question theories and introduce new ones. Unfortunately, it is often the great and respected thinkers who end up slowing the progress of human thought. Aristotle was a brilliant philosopher whose theories explained much of the natural world, often incorrectly. He was so esteemed by the scientific community that even 1，200 years after his death, scientists were still trying to build upon his mistakes rather than correct them!
Brilliant minds can intimidate upandcoming thinkers who are not confident of their abilities. They often believe they are inferior to the minds of giants such as Aristotle, leading many to accept current paradigms instead of questioning them.
I, like many thinkers of the past, once believed in my mental inferiority. I was certain that my parents, my teachers-adults in general-were always right. They were like a textbook to me; I didn't question what was written on those pages. I respected them, and accepted whatever they told me. But that attitude soon changed. My mind's independence was first stimulated in the classroom.
A stern, 65yearold elementaryschool science teacher once told me that light is a type of wave. I confidently went through years of school believing that light is a wave. One day，however I heard the German exchange student mention that light could be made up of particles. As the others laughed at his statement, I started to question my beliefs.
Maybe the teachers and textbooks hadn't given me the whole story. I went to the library, did some research and learned of the lightasawave versus lightasaparticle debate. I read about Einstein's discovery of the dual nature of light and learned the facts of a paradox(悖论) that puzzles the world's greatest thinkers to this day. Light behaves as both a particle and a wave, it is both at once. I realized I had gone through life accepting only half of the story as the whole truth.
Each new year brought more new facts, and I formulated even more questions. I found myself in the library after school, trying to find my own answers to gain a more complete understanding of what I thought I already knew. I discovered that my parents and teachers are incredible tools in my quest for knowledge, but they are never the final word. Even textbooks can be challenged. I learned to question my sources, I learned to be a thinker. I once believed that everything I learned at home and at school was certain, but I have now discovered to reexamine when necessary.
Questions are said to be the path to knowledge and truth, and I plan to continue questioning. How many things do we know for sure today that we will question in the future? At this moment, I know that our sun will burn for another five billion years, and I know nothing can escape the gravity of a black hole. This knowledge, however, may change in the next 20 years-maybe even in the next two. The one thing we can control now is our openness to discovery. Questions are the tools of open minds, and open minds are the key to intellectual advancement.

10 . When I was in fourth grade, I worked part-time as a paperboy. Mrs. Stanley was one of my customers. She’d watch me coming down her street, and by the time I’d biked up to her doorstep, there’d be a cold drink waiting. I’d sit and drink while she talked.
Mrs. Stanley talked mostly about her dead husband, “Mr. Stanley and I went shopping this morning.” she’d say. The first time she said that, soda(汽水) went up my nose.
I told my father how Mrs. Stanley talked as if Mr. Stanley were still alive. Dad said she was probably lonely, and that I ought to sit and listen and nod my head and smile, and maybe she’d work it out of her system. So that’s what I did, and it turned out Dad was right. After a while she seemed content to leave her husband over at the cemetery(墓地).
I finally quit delivering newspapers and didn’t see Mrs. Stanley for several years. Then we crossed paths at a church fund-raiser(募捐活动). She was spooning mashed potatoes and looking happy. Four years before, she’d had to offer her paperboy a drink to have someone to talk with. Now she had friends. Her husband was gone, but life went on.
I live in the city now, and my paperboy is a lady named Edna with three kids. She asks me how I’m doing. When I don’t say “fine”, she sticks around to hear my problems. She’s lived in the city most of her life, but she knows about community. Community isn’t so much a place as it is a state of mind. You find it whenever people ask how you’re doing because they care, and not because they’re getting paid to do so. Sometimes it’s good to just smile, nod your head and listen.
