Next time you find yourself tending to your flower garden, you may want to stay quiet.The flowers are listening.
Israeli scientists discovered that the plants hear bees approaching and attempt to lure them in with sweeter nectar (花蜜).In several experiments, they found that playing audio recordings of buzzing bees around certain flowers will cause the sugar concentration in the nectar to rise by about 20% in less than five minutes.Such a rapid reaction by plants to sound had never previously been reported.Just to make a comparison, the researchers also tried a higher frequency noise—like that made by a mosquito or a bat—and the flowers did not respond.
The authors pointed out that the behavior is actually in line with the natural order of things, considering that a plant’s ability to sense its environment and respond to it is critical for its survival.So, it seems that plants have some sort of consciousness.
This is not the first time that plants have reacted to the sound around them.In a 2009 study, the researchers found that women’s voices help make plants grow faster.In that experiment, tomato plants were found to grow two inches taller when they were tended to by a female gardener.
What if we told you that a potato chip bag left on the floor of a break room could listen in on office gossip?As people were talking around the potato chip bag, they were sending tiny sound vibrations (震动) into the air.Those vibrations then hit lifeless objects around the room.If you had a camera that was zoomed in on one of those objects extremely closely, in theory, you could actually see the object move along with the vibrations.You could then feed that video into a computer program that could translate the vibrations and you could play back the audio of the conversation that just took place.
So the next time you’re at the botanical garden or in a grocery aisle, be careful what you say.Someone—or something—might be listening.

【推荐1】Once there were many thousands of Gourma Desert (沙漠) elephants in Mali, a country in West Africa. Now, there are fewer than four hundred.
Why did the number of the elephants drop so quickly? On the one hand, the elephants’ main lake, their only water source (来源), dried up. On the other hand, the land which the elephants lived on was overused by humans.
To protect the elephants’ living environment, the Mali Elephant Project (MEP) was started in 2007. MEP met with local people and helped them make rules of using land and water. As a result, the situation became better and there was more food, forest and grassland.
However, from 2012 to 2016, poaching (偷猎) and illegal trade in the elephants increased rapidly. Eighty-three elephants were lost in 2015 alone, and another fifty-one elephant were killed in 2016. “If this situation goes on, all the Gourma elephants will be killed by 2020,” said a member of MEP.
Luckily, the voice of MEP was heard. More organizations (组织) have joined together to educate the local people that trading elephants is against the law. Elephant poaching has dropped to a very low level. The local people have learned to live peacefully with the elephants, one of the wildlife treasures in the world.

【推荐2】Back in 2012, Dylan Mayer was 19 years old. He was a few years into a new passion: scuba (水肺) diving. He says spending time under water is like visiting an alien planet full of strange creatures.
Dylan grew up in Maple Valley Washington, just outside of the liberal blue bubble of Seattle. Dylan learned young how to hunt and do farm work. On October 31, 2012, he decided to marry his love of scuba diving with his desire to be self-sufficient and harvest his own food. That gray morning, the goal was to pull a giant pacific octopus from its den, wrestle it to the surface and take it home for dinner.
He and a friend headed to the popular dive site at Cove 2 in West Seattle. With his bare hands, Dylan caught an 80-pound cephalopod (头足类动物). “The key is to stay calm. Once you start to panic, you’ll drown,” said Dylan, recalling his 45-minute hand-to-tentacle (触须) battle with the octopus.
But when he hauled it out of the water, people nearby didn’t look very happy. Dylan and his dive partner threw the octopus in the back of their truck and quickly left the scene.
Even though what Dylan did was perfectly legal and even though octopus is on restaurant menus all over the Northwest, the taking of this particular octopus touched a nerve. Adult members of the diving community that Dylan was so excited to be a part of not only roundly rejected him, but also threatened to kill him and his family. However, one diver from the Cove 2 community rose above the criticism to guide this young diver.

【推荐3】A woman was walking her dog along a beach in New Zealand in late June when she saw something that looked like a white ball in the sand. It turned out to be a young Emperor Penguin that was lost. At his age, he should have been close to the Antarctic, swimming for fish and playing on the ice floes (冰川). But this penguin started swimming north and just kept going.
The penguin attracted a lot of attention in New Zealand. It has been 40 years since an Emperor Penguin was last seen there. Researchers at the Department of Conservation were called in. They decided to watch the penguin closely, but not to disturb it in any way. Many New Zealanders came to Peka Peka Beach to look at the elegant penguin. They were careful to keep their dogs away from him so he wouldn’t be frightened.
The public nicknamed the animal Happy Feet. Researchers started to notice that Happy Feet didn’t seem well. It turned out that he had been eating the sand from the beach, likely thinking it was snow.
The public raised more than 11, 000 pounds for an operation to get the sand out of his stomach. The operation was a success, and Happy Feet was taken to a zoo in Wellington, NZ. A group of experts met to decide how to help Happy Feet return to the wild.
Last Sunday, they put him on a boat called the Tangaroa, in a specially built ice-filled box and took him out into the Southern Ocean, southeast of New Zealand. There, they released him into the ocean, which is his natural habitat. He took one last look at his human helpers and then dived into the ocean.
“Emperor Penguins spend their first five years at sea,” said Peter Simpson of New Zealand’s Department of Conservation. “What happens now is up to the penguin.”
Happy Feet was fitted with a satellite transmitter (发射机) so they can monitor his progress using the Internet. So far, the trackers show that he swam northeast for a little while before getting his bearings and heading south.

【推荐1】We often hear honesty is the best policy, and no one likes to be called a liar. But is dishonesty always wrong? Not necessarily.
According to psychologists, there are two types of lies: lies that help your relationships and the people around you are called pro-social lies;and lies that hurt them are called antisocial lies.
How often have you clicked “Like” on Wechat Moment, not because you actually like what your friends posted, but because you want to show your support? This white lie is an example of a pro-social lie. But who people tell lies on social networks to make their own lives seem more exciting, or to make others jealous, this is antisocial lying.
Workplace lies range from harmless lies to destructive untruthful statements. An example of a pro-social workplace lie is complimenting someone on their presentation — even though it was only average — because you know they were nervous beforehand. In this case your intention is simply to protect your colleague’s feelings. However, people sometimes tell bigger lies at work for the purpose of avoiding blame or to stay on the boss’s good side. These are antisocial lies. They are antisocial because your boss is likely to discover the truth and as a result, will probably stop trusting you.
Lying is also a significant part of the natural world. So it’s little wonder we resort to it almost reflexively. Human babies sometimes pretend to cry, check to see if anyone is listening. and then start crying again. By the age of five, children learn to say things that are completely untrue, and most nine-year-olds have mastered keeping secrets to protect themselves.
Lying can be incredibly harmful to our relationships and to the people around us. But that’s only true for antisocial lies. Pro-social lies. have the opposite effect — they can actually help us.

C.The occasion where it is told. | D.The people it is told to. |
A.Admit to | B.Turned to. |
C.Show respect to | D.Look forward to. |

B.Lying always hurts both the liar and the person being lied to |
C.Lying on social media is pro-social, but face-to-face lying isn’t . |
D.Sometimes, making people feel good outweighs telling the absolute truth. |
A.Lies That Harm Us | B.Lying is A Second Nature |
C.Lies That We Need to Tell | D.Honesty is the Best Policy |

【推荐3】Seven out of the eight planets in our solar system were named after Greek or Roman Gods. You’re living on the only exception to that rule.
The word “earth” has roots in the Old English term “eorþe”. Eorþe had multiple meanings like “soil”, “dirt”, “ground”, “dry land” and “country”. Yet the story didn’t begin there. Old English is the earliest known stage of what became our modern English tongue. Used until about 1150 C.E., it evolved from a parent language that scholars call “Proto-Germanic”. The German that’s spoken today is part of the same linguistic family. “Earth” and “eorþe” are therefore related to the modern German word “Erde”. Not only is this the German language’s name fox our home planet, but it can also be used to refer to dirt and soil.
Our dear Each has relatives in some other languages, too, For example, there’s the Old Saxon “ertha”, the Old Frisian “erthre” and the Dutch word “aarde”. All these likely originate from a Proto-Germanic term that was never recorded. Nevertheless, linguists have been able to go back and reconstruct this mystery word. Spelled “ertho” in scholarly texts, it’s always marked by an asterisk (星号). This asterisk acknowledges the lack of written confirmation that the word was really used.
Nobody knows when people started using words like “Earth” or “Erde” to refer to the planet as a whole and not just the ground they walked on. Back in 1783, German astronomer Johann Elert Bode named the seventh planet from our sun “Uranus” (after a Greek god). And though Pluto is no longer considered a planet, we know that 11-year-old Venetia Burney named it in 1930. But if a single person gave planet Earth its English name, his or her identity has been lost to the sands of time.
Still, it’s clear that while Mercury, Venus, Mars, Jupiter, Saturn, Uranus and Neptune all started out as the proper names of ancient gods, “Earth” did not. That’s why our planet is sometimes called “the earth” with a lowercase (小写字母) “e”.

【推荐2】Where did novel corona-virus come from?
As COVID-19 is spreading throughout the world, an important question has yet to be answered: where did the virus come from?
The latest study indicated that pangolins (穿山甲) may be an intermediate host of the virus, according to Xinhua. However, bats are suspected to be the original cause.
We don’t know the source yet, but there’s pretty strong evidence that this is a bat origin corona-virus,” said Peter Dazsak, president of EcoHealth Alliance, an environmental nonprofit, according to The New York Times. “When you look at the genetic sequence (基因序列) of the virus, and you match it up with every known corona-virus, the closest relatives are from bats,” Dazsak also told CNN.
So why are bats the source of so many deadly kinds of viruses but they don’t suffer from any symptoms? As the only flying mammal (哺乳动物) with long lifespan, bats’ body temperature is high, similar to a fever. It’s this fact that may contribute to bats’ unique immune system (免疫系统) in protecting them from the ill effects of viruses.
But are bats truly to blame for the virus or should we be blaming ourselves? Whether we destroy the forests where bats live or they end up on our plate, it’s the fault of humans for decreasing the distance between us and virus-carrying bats. Bats are an important animal in our ecosystem when it comes to pollinating (授粉) many fruits such as mangoes and bananas. We need to allow them to continue pollination and keep them away from our markets and mouths.

B.Scientifically, it is confirmed that bats are the very original cause. |
C.Pangolins are agreed to be the intermediate host of the virus. |
