Plants Scream in the Face of Stress
For the first time, researchers appear to have evidence that like animals, those plants deprived of water or 1. (force) to endure bodily harm can let out their pain. The study, 2. has yet to be published in a scientific Journal, adds another dimension to scientists 3. (grow) understanding of how plants detect and interact with their surroundings.
In recent years, it has become very clear that plants are more sensitive than researchers 4. (think). They respond when touched by insects and turn toward sources of light. "Plants are not just robotic stimulus-response devices," said Frantisek Baluska of the University of Bonn in Germany. "They're living organisms which have their own problems/'
Actually making their suffering hearable, however, is another matter entirely. 5. (test) that possibility, a team led by Itzhak Khait, a plant scientist at Tel Aviv University in Israel, placed microphones capable of detecting ultrasonic frequencies (超声波频率)four inches from tomato and tobacco plants. The researcher then either stopped watering them or cut their stems.
Measuring in the range of 20 to 150 kilohertz (千赫).the researchers found that even happy, healthy plants made the occasional noise. But when cut, tobacco plants emitted 6. average of 15 sounds within an hour of being cut 7. tomato plants produced 25 sounds.
8. researchers aren't yet sure how plants produce these sounds, Khait and his colleagues proposed one possibility in their paper 9. as water travels through the plants' tubes, air bubbles will form and explode, producing small vibrations.
All this "screaming” caused by stress wasn't in a range detectable by human ears. But organisms that can hear ultrasonic frequencies—like mice, bats or perhaps other plants—10. possibly hear the plants cries from as far away as 15 feet.

Phone-surfing Results in More Purchases
Leaving your mobile phone at home when you go shopping could prevent mindless overspending, a new study suggests. Research from the University of Bath discovered that when people are distracted by their mobiles during a trip to the supermarket their shopping bills 1. rise by an average of 41 per cent. Attention-weakening devices also encourage shoppers to wander along more shelves, 2.they come across more products.
In one study, 294 people aged between 18 and 73 at four Swedish supermarkets wore eye-tracking glasses throughout a shopping trip to measure where they went and 3.they looked at. Their receipts were then used 4.(assess) their spending. Those using a mobile phone spent on average £33.73 compared to an average of £23.91 for those who did not.
A second study of 117 shoppers found those with mobile phones spent longer in the store, 5.(give) more attention to shelves. They also spent an average of £36. This study found shoppers using a mobile phone spent on average £36.16 on 20.85 items, compared to £25.59 on 13.22 products.

It is a rough world out there. Step outside of a shopping mall and you could break your leg 1.(slip)on the doormat. Luckily, if the doormat failed to warn of coming danger, a successful lawsuit(官司) might compensate you for your troubles. Since the early 1980s, juries have begun holding more companies responsible for the customers' misfortunes.
Feeling threatened, companies responded by writing longer warning labels, trying to anticipate every possible accident. Today, even ladders carry a label several inches long that 2.(warn) among other things, that you might fall off. While warnings are often necessary for companies, many still feel uncertain whether those labels can protect 3. from legal responsibility if a customer is injured. Actually, about 50% of the companies lose when 4.(take) to court by the injured customer.
Now the tide appears to be turning 5. personal injury claims continue to grow, some courts are beginning to side with defendants(被告), especially in cases6. a warning label probably wouldn't have changed anything.

Procrastination - a Virtue When It Comes to Creativity?
Psychologist Adam Grant, from the University of Pennsylvania in Philadelphia, argues that people who “put off” solving a task for a little while - thus engaging in moderate procrastination -- are often able to come up with 1. (original) ideas about how to solve that task than people who get started on their work right away.
Grant makes this argument in the book Originals: How Non-conformists Change the World and reiterates it in a popular TED talk 2. he says that “procrastination is a vice when it comes to productivity, but it can be a virtue when it comes to creativity.” This point of view seems 3. (find) some support in existing studies that indicate a correlation between creativity and “putting things off.”
Grant explains that the link between moderate procrastination and originality likely 4. (exist) because when we actively put off a task for a while, our preoccupation with the task itself does not disappear. Instead, the unfinished work “runs in the background” of our brains, 5. (buy) us time to find innovative solutions.
One study 6. (publish) in Personality and Individual Differences in 2017 also found a link between creative ideation (coming up with creative ideas) and active procrastination. It suggested that among 853 undergraduates at Chinese universities, “active procrastinators” may be more prone to creativity.
Boredom 7. have something to do with this boost in creative thinking. Older research from the University of Florida in Gainesville suggests that people who procrastinate may be more prone to boredom than their peers.
And while boredom itself is a concept that sometimes has negative connotations, studies 8. (show) that allowing ourselves to feel bored for a while can boost our creative abilities. The researchers explain that this may be because when we are bored, we allow our minds to wander, thus “training” our imaginations.
Finally, 9. putting off a task forever out of fear and self-doubt may be paralyzing and unhelpful, a little bit of “directed” procrastination will likely not be harmful and may allow us to assess the task at hand more imaginatively.
And for some of us, that pressure of looking a deadline straight in the eye can be just 10. we need to keep us on our toes. As Calvin, one of the main characters in the comic strips Calvin and Hobbes, once said : “You can’t just turn on creativity like a faucet. You have to be in the right mood,” and that mood is “last - minute panic.”
