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.
1.Which of the following best explains "lure" in Paragraph 2?

Do you ever find yourself spending time on product reviews when you buy something online, only to find that the product you bought is junk(废物)? New research led by Dr. Powell of Stanford University may explain why this happens: it boils down to the number of reviews a product has.
The study found that when choosing between two products online, people tend to favor the one with more reviews despite the fact that the more reviewed product is of lower quality. This is because when shopping online, consumers engage(从事)in a type of “social learning”, where they learn from observing the decisions of other people and the results of those decisions. People attach more importance to the choices of others. When evaluating online products, the item’s rating and number of reviews can be helpful to an unsure customer. But a new study, published in the journal Psychological Science, found that consumers don’t check those figures to learn their true meaning enough. So they fail to do a simple task when viewing online rating and reviews, leading them to purchase products of poor quality. When shopping online, consumers engaging in social learning become informed from the decisions of others. For example, you’re more likely to buy a book at the top of the New York Times’ best-sellers list or buy an app that’s been downloaded millions of times. But looking at other people’s choices is only a part of social learning. However, how people understand or fail to understand this data is affecting their decision-making in a negative way. Overcoming this bias(偏见)is difficult because consumers find comfort in popularity.
Powell and his colleagues also found evidence of this trend beyond the study. “It doesn’t necessarily mean that better things don’t become more popular, but as a consumer, when you’re looking at the number of reviews, it’s not telling you anything,” said Dr. Powell.
1.What does the underlined phrase “boils down to” probably mean?
A. is equal to B. results in C. is due to D. focuses on
2.What belief do unsure consumers hold when purchasing products?
A. Rating determines quality. B. Popularity is good.
C. Bad reviews should be ignored. D. More-reviewed products is poor.
3.What do Dr. Powell’s words mean in the last paragraph?
A. The product’s rating often fails to reflect true quality.
B. Usually consumers will find much comfort in popularity.
C. Consumers should distinguish good things and bad things.
D. Consumers should follow others when buying things online.
4.What is probably the best title of the text?
A. How to Purchase Online B. Why We Buy Junk Online
C. Why We Ignore Bad Reviews D. How to Review a Product

Do you like to flaunt your expensive items? You could find yourself without friends! Scientists prove that expensive status symbols make you look less socially attractive.
Items such as a fancy car and a Rolex watch are often thought to increase our social standing and often come with a high price tag(标签).According to the latest research, however, it has the opposite effect and people would prefer to be friends with someone who places less value on material objects.
“Often we think that status symbols will make us look more socially attractive to others, “says Stephen Garcia, the study's lead author from the University of Michigan. He adds, “However, our research suggests that these status signals actually make us look less socially attractive.
The researchers conducted six studies which assessed how people presented themselves and how people viewed strangers. People who chose to wear higher status items tended to get a negative response, but people wanted to be friends with people who preferred lower status symbols.
The study took the role of the luxury item to see if it was possible that the expensive item itself played a part in people's reactions. The definition of a status symbol changed based on a person's socioeconomic status, but the same effect of keeping off potential friends was seen regardless of social position.
"At a social level, we may be wasting billions of dollars on expensive status symbols that finally keep others from wanting to associate with us, "says Kimberlee Weaver Livnat at the University of Haifa. She says, "And to the extent that close friendships are important to well-being, we may be unintentionally hurting ourselves.”
However, Patricia Chen of the National University of Singapore said this does not necessarily mean status symbols are a bad thing. She says, "Our findings right now only apply to the formation of new friendships, Status symbols may be beneficial at other times and in other settings, such as when trying to establish new business contacts.”
1.What does the underlined word "flaunt" in paragraph I mean?
A.Show off. B.Get rid of.
C.Give away. D.Hand in.
2.Which is the negative influence of expensive status symbols?
A.Lowering people's social status.
B.Preventing people from making friends.
C.Doing harm to people's health absolutely.
D.Changing people s consumption concept.
3.Who may be more popular among friends according to the text?
A.People who are very rich. B.People with high social status.
C.People who keep a low profile. D.People with charming appearance.
4.What attitude does Patricia Chen have towards status symbols?
A.Positive B.Unconcerned.
