Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are frequently blamed for a number of things, from thumb injuries and headaches to house fires.
The theory is that the bees navigation (导航) systems are damaged by the radiation that is given off by mobile phones. Bees have a built-in system a bit like GPS and this helps them find their way back to their hive. But recently, thousands of bees have failed to find their way home.
The problem was first noticed by beekeepers in America and is a lot more complicated than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated (授粉) by them.
A.Bees are losing their way. |
B.Nobody has proved the theory is true. |
C.More evidence is provided to support the theory. |
D.It is believed they are dying far from their hives. |
E.Without bees, the crops can’t continue to grow. |
F.The situation needs to be evaluated by the world’s best scientists. |
G.One theory even blames mobile phones for the disappearance of bees. |

【推荐1】When most people go to the famous amusement parks in Orlando, Florida, they miss some of the natural wonders the State has to offer. It was in Citrus County on the beautiful west coast of Florida that we went to see the manatee (海牛), which occupies coastal waters and rivers.
Our days started early in the morning at Homosassa Springs. We boarded a boat with Captain Traci Wood from Native Vacations. Having spotted two manatees just below the water, Captain Traci stopped the boat as they slowly swam toward us. They used their tails to drive themselves, steering with their flippers(脚蹼), gracefully moving their bodies through the water in our direction. Our boat was soon surrounded by other members of this gentle species.
Soon we continued our journey. Within a few minutes Captain Traci stopped the boat again and we were given instructions. Whatever you do, she said, remember the three golden rules: minimize splash (拍水) noise; act with very slow movements; and when you touch one of these friendly, gentle grey giants on the back or stomach, never touch with more than one hand at a time. The Endangered Species Act forbids touching a manatee unless it touches you first, and they will let you know. The protection of this endangered species is taken very seriously. But this won’t affect the experience in the least. Most Homosassa manatees are very social and will come to you.
Manatees feed strictly on plants, and they eat a great variety of species, including hyacinth and water lettuce. They’re very big, measuring 3 to 5 metres and weighing as much as 1,600 kilos. Despite this, they look very cute. Manatees are of course wild creatures, although when face to face with them, you’re unlikely to feel any fear.
From December to March, groups of manatees escape the cold winter ocean and bathe in the warm waters near power plants and coastal springs that stay about 23 degrees year-round. Divers and swimmers come to Florida from all over the world for a chance to swim or interact with the manatee in its natural environment, rich in marine vegetation. This rich source of food makes this area an ideal place for the manatees. So the manatees arrive every year by the hundreds to find warmth, nourishment(营养) and maybe, just maybe, to visit us, the curious humans.
1. According to Captain Traci, those who swim with manatees mustn’t________.A.be under the age of twelve | B.make any noise to annoy them |
C.swim so slowly as to be caught by them | D.touch them with both hands at the same time |
A.They live on other sea animals. | B.They are not dangerous to humans. |
C.They remain curious about humans. | D.They are among the biggest sea animals. |
A.To stay away from the cold weather. | B.To interact with human beings. |

【推荐2】My folks bought their first house in the early 1940s after Dad got a better job in Marquette, Michigan. We lived just inside the city limits in what was still a rural area.
In the spring of 1948, when I was 6 years old, my parents bought a calf (小牛) to replace our cow, which had been killed the year before. So one day we drove to a local farm and returned with a white and brown calf we named Tubby.
We didn’t own a truck, so Tubby rode home in the backseat of Dad’s car with my 9-year-old brother, Steve and me. As you can imagine, the trip was a lot of fun for us kids.
Later that summer, Mom thought it would be cute to take a picture of me sitting on Tubby’s back. All went well until the flashlight of the camera sent Tubby charging off on a run, with me holding on for dear life and my heart pulled to my throat.
I lasted for about 30 feet before I hit the ground. Mom was quick enough to shoot a follow-up picture, so we had photos of me both on and off Tubby!
When summer had passed, the day arrived for poor Tubby to fill our freezer (冰柜). I must have been somewhere else with my mom on the fateful (决定性的) day, because I have no memory of what happened. All I knew was that the barn (畜棚) was empty, and that we had plenty of meat for dinners.
I hadn’t lived on the farm like my mother, so I didn’t understand that what had happened to Tubby was not unusual. Livestock (家畜) aren’t meant to be pets, and most farm kids know and accept the truth.
Whenever we had beef for dinner, I would tearfully ask, “Is this Tubby?” This went on for a couple of months until Dad had enough and declared, “No more cows!” That made me feel better about poor Tubby.
1. Why did the parents buy Tubby?A.To raise it for meat. | B.To produce enough milk for the kids. |
C.To keep the kids company. | D.To have Tubby help with farm work. |
A.The writer witnessed Tubby killed. |
B.The writer felt happy to see the freezer filled with meat. |
C.The writer’s mother thought it natural to kill Tubby for meat. |
D.The writer felt excited on Tubby’s back when it was running off. |

But instincts and training aren’t the only keys to animals’ behavior. Scientists say animals’ thoughts and feelings also influence their actions. Animals often make choices, plans, and sensible changes. They can help others and solve problems. Some even make and use tools!
If animals could talk, what would they say about their thoughts and feelings? A gorilla (大猩猩) born in captivity (关在笼子里) has helped answer that question. Koko, a gorilla, was taught to use sign language. She has learned hundreds of words!
Koko once had a pet cat she named All Ball. “Koko love Ball,” she signed. “Soft good cat.” One time, she blamed the cat for biting her by signing “You bad dirty toilet!” When her pet died, Koko cried. “Sad for sleeping cat,” she signed.
Koko calls herself “fine animal gorilla”. She uses sign language to argue, joke, and ask and answer questions.
“Most animals can’t use words to tell us their thoughts,” says Dr. Jonathan Balcombe. “But Koko shows us that animals have their own ideas and feelings.” Dr. Balcombe is a scientist at the Humane Society of the United States. He says there’s even more to discover about animals through field studies. In field studies, people watch animals in their natural environment.
“Scientists who study animals’ natural behaviors learn how animals live and think,” Balcombe says. “That knowledge can help others respect every animal who shares the planet with us.”

【推荐1】Cheating is considered to be a major problem in colleges and universities. Colleges and universities across the US have decided to do more than talk about the rise in student cheating.
We frequently hear about “the good old days”, when Americans were better, happier, and more honest. But were they more honest? Maybe yes, a long time ago when life was very different from what it is today.
School children used to know the story of how Abraham Lincoln walked five miles to return a penny he’d overcharged a customer. It’s the kind of story we think of as myth. But in the case of Lincoln, the story is true — unlike the story of George Washington and the cherry tree. Washington’s first biographer invented the tale of little George saying to his father, “I cannot tell a lie. I did it with my ax.” What is important in both stories, however, is that honesty was seen as an important part of the American character.
And these are just two stories out of many. Students in the last century usually didn’t read “fan” stories. They read stories that taught moral values. Such stories pointed out quite clearly that children who lied, cheated, or stole came to bad ends.
Parents may have further reinforced those values. It’s difficult to know. We do know that children didn’t hear their parents talk of cheating the government on income taxes — there weren’t any. The vast majority of Americans still believe that honesty is an important part of the American character. For that reason, there are numerous watch-dog committees at all levels of society.
Although signs of dishonesty in school, business, and government seem much more numerous in recent years than in the past, could it be that we are getting better at revealing such dishonesty? There is some evidence that dishonesty may ebb and flow (起伏). When times are hard, incidents of theft and cheating usually go up. And when times get better such incidents tend to go down.
Cheating in school also tends to ebb and flow. But it doesn’t seem linked to the economy. Many educators feel that as students gain confidence in themselves and their abilities, they are less likely to cheat. Surprisingly, some efforts to prevent cheating may actually encourage cheating — a person may feel “they don’t trust me anyway,” and be tempted to “beat the system.” Distrust can be contagious (传染的). But, so can trust!

【推荐2】Now that members of Generation Z are graduating college this spring—the most commonly-accepted definition says this generation was born after 1995, give or take a year—the attention has been rising steadily in recent weeks. Gen Zs are about to hit the streets looking for work in a labor market that’s tighter than it’s been in decades. And employers are planning on hiring about 17 percent more new graduates for jobs in the U.S. this year than last, according to a survey conducted by the National Association of Colleges and Employers. Everybody wants to know how the people who will soon inhabit those empty office cubicles will differ from those who came before them.
If “entitled” is the most common adjective, fairly or not, applied to millennials (those born between 1981 and 1995), the catchwords for Generation Z are “practical and cautious”. According to the career counselors and expert who study them, Generation Zs are clear-eyed, economic pragmatists. Despite graduating into the best economy in the past 50 years, Gen Zs know what an economic train wreck looks like. They were impressionable kids during the crash of 2008, when many of their parents lost their jobs or their life savings or both. They aren’t interested in taking any chances. The booming economy seems to have done little to assuage this underlying generational sense of anxious urgency, especially for those who have college debt. College loan balances in the U.S. now stand at a record $1.5 trillion, according to the Federal Reserve.
One survey from Accenture found that 88 percent of graduating seniors this year chose their major with a job in mind. In a 2019 survey of University of Georgia students, meanwhile, the career office found the most desirable trait in a future employer was the ability to offer secure employment (followed by professional development and training, and then inspiring purpose). Job security or stability was the second most important career goal (work-life balance was number one), followed by a sense of being dedicated to a cause or to feel good about serving the great good.
