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 compare, 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 point 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 would seem 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 up to 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 (振动) into the air. Those vibrations then hit lifeless objects around the room. Now imagine 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 can 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, careful what you say. Someone-or something-might be listening.

Deep in the middle of Sri Lanka, a massive column of rock reaches out from the green tropical forest. It is 660 feet tall and features frescoes (壁画), graffiti, and landscaped gardens.
The rock is known as Sigiriya and holds a special place in the island's cultural history.
It was established as the stronghold of a king over 1,500 years ago, and today the Sigiriya complex stands as one of the earliest preserved examples of ancient urban planning.
Located in the Central Province, the column of rock is somewhat central to the country. The rock is known as Sihagiri, meaning "Lion Rock", a nod to the giant animal carved from stone which greeted visitors at the entrance.
In 476 BC. King Dhatusena ruled over Sri Lanka. One of his illegal sons, Kashyapa, wanted the throne (王位). Kashyapa overthrew Dhatusena and drove his brother Moggallana to Southern India. Kashyapa crowned himself king in 477 BC.
King Kashyapa chose Sigiriya as his palace because its position was an advantage to the defensive stronghold, offering fantastic 360-degree views. Plans to build a city quickly unfolded and after several years, the Sigiriya complex had become a business center for the new King.
Sigiriya was both a palace and a fortress (堡垒); the overall complex featured five gates and measured just under 3 km by just over 1 km. The site plan consisted of a fort，an upper palace on the top of the rock,and lower palaces at ground level. The king also constructed gardens throughout，and for protection a river with walls surrounded the complex.
Frescoes decorate the western side of the rock, along with the mirror wall, a brick face covered in a highly-polished white plaster. When new, the wall was said to be able to produce Reflections.
Over time the Mirror Wall became a graffiti board, covered in verses written by visitors. Known as "Sigiri Graffiti", some of the messages date to the 8th century CE.
1.It is implied in the passage that Sigiriya was built to ______________.
A.preserve the culture of Sri Lanka B.prove the ancient urban planning
C.keep the King from being attacked D.protect the green tropical forest
2.According to the passage, some visitors would _________.
A.have a reflection before the Mirror Wall
B.leave comments on the Mirror Wall
C.draw beautiful paintings of girls on the wall
D.be lost in thought before the Mirror Wall
3.What do we know about Sigiriya?
A.Its entrance is carved like a lion. B.Its gardens are at ground level.
C.Its western side is a mirror. D.Its palaces are on the top of the rock.
4.What is the best title of the passage?
A.The giant lions in Sri Lanka. B.The pearl of the Indian Ocean.
C.The Lion Rock of Sri Lanka. D.The mirror wall in a rock.
"Keep your eyes open. This is where the Ewoks live.'' The one-hour drive outside of San Francisco, covered in clouds along windy roads, has inspired my husband to say this sentence at least a dozen times.
We finally arrive at Muir Woods National Park. I explain the strange green stuff on trunks of trees as we pass by--mos (苔藓), something my 5-year-old son Cole has never seen in the desert where we live.
"Mom, are Ewoks real? I think they maybe aren't real. " There's a question in Cole's voice,like he's trying on this idea.
We've been down the road of pretending versus reality before, what with all the talk of superheroes and such around our house. "I think you are right. Ewoks are just in the movies. But it would be cool if they were real, right ?"
Cole's silent for a while, thinking. "I just saw an Ewok’s ear back there!" Coles spotted an additional Ewok arm and one full body of the tiny hairy creatures. It does indeed look like we are in the Ewok forest of Star Wars.
Cole's imagination is more than I can understand. What do plants eat? Which is the best planet? Which rocks float? He loves life. He loves his inner world and outer existence equally.
I hear a lot of worry from parents about media sucking the souls from our children, taking away their time for creative play. For us, this hasn’t been the case. Cole and his brother are quite knowledgeable in the realities of life when it comes to Angry Birds, Curious George, and the adventures of Indiana Jones. These characters, and others of their own invention, live in my home like visitors, joining us on walks and outings. I appreciate them, though not all the time, for the company they give my sons and their busy minds.
I think of media characters as an add-on to already busy minds, by carefully monitoring who gets invited into our lives, they become part of the parenting team. They teach loyalty adventure, curiosity--lessons I'm trying to convey, but in a much cooler way than I can.
Pretence is awesome. It provides practice for real life without the ordinary interfering.
1.Where are the family heading for?
A.The cinema. B.A park. C.San Francisco. D.A desert.
2.What can we know about Cole from the passage?
A.He is proud of himself. B.He is full of curiosity.
C.He is courageous. D.He is considerate.
3.What do many parents think of their children playing via media?
A.It wastes children's time.
B.It can make their children relaxed.
C.It can engage their children in learning actively.
D.It can accompany their children in their absence.
4.What's the authors attitude to the media characters in parenting children?
A.Indifferent. B.Critical. C.Supportive. D.Disapproving.

I recently had a bad cold. My Chinese friends suggested that 1 drank some hot water, what made me think of some common home remedies（家庭疗法）back in the US.
When I was about 10, I got the flu, and my mom didn't take me to the doctor. First, she had me to take several hot showers. Then, she told me to put on as many clothing as I could. Before that, I slept under a thick blanket. I was sweating so much that I felt like I’d just taken a bath. Within a day, my flu gone.
This kind of sweating is the common home remedy in the West. Another remedies include drinking ginger soda when you have a stomachache and eat chicken noodle soup when you have a cold.
