1 . Early fifth-century philosopher St．Augustine famously wrote that he knew what time was unless someone asked him．Albert Einstein added another wrinkle when he theorized that time varies depending on where you measure it．Today's state-of-the-art atomic（原子的） clocks have proven Einstein right．Even advanced physics can't decisively tell us what time is, because the answer depends on the question you're asking．

Forget about time as an absolute．What if，instead of considering time in terms of astronomy,we related time to ecology？What if we allowed environmental conditions to set the tempo（节奏） of human life？We're increasingly aware of the fact that we can't control Earth systems with engineering alone，and realizing that we need to moderate（调节）our actions if we hope to live in balance．What if our definition of time reflected that？

Recently，I conceptualized a new approach to timekeeping that's connected to circumstances on our planet，conditions that might change as a result of global warming．We're now building a clock at the Anchorage Museum that reflects the total flow of several major Alaskan rivers，which are sensitive to local and global environmental changes．We've programmed it to match an atomic clock if the waterways continue to flow at their present rate．If the rivers run faster in the future on average，the clock will get ahead of standard time．If they run slower，you'll see the opposite effect．

The clock registers both short-term irregularities and long-term trends in river dynamics．It's a sort of observatory that reveals how the rivers are behaving from their own temporal frame（时间框架），and allows us to witness those changes on our smartwatches or phones．Anyone who opts to go on Alaska Mean River Time will live in harmony with the planet．Anyone who considers river time in relation to atomic time will encounter a major imbalance and may be motivated to counteract it by consuming less fuel or supporting greener policies．

Even if this method of timekeeping is novel in its particulars，early agricultural societies also connected time to natural phenomena．In pre-Classical Greece，for instance，people“corrected”official calendars by shifting dates forward or backward to reflect the change of season．Temporal connection to the environment was vital to their survival．Likewise，river time and other timekeeping systems we're developing may encourage environmental awareness．

When St．Augustine admitted his inability to define time， he highlighted one of time 's most noticeable qualities：Time becomes meaningful only in a defined context．Any timekeeping system is valid，and each is as praiseworthy as its purpose．

3 . During the initial stages of instructed L2 (the second language) acquisition students learn a couple thousand, mainly high frequency words. Functional language proficiency, however, _______mastery of a considerably large number of words. It is therefore _______ at the intermediate and advanced stages of language acquisition to learn a large vocabulary in a short period of time. There is not enough time to _______the natural (largely incidental) L1 (the first language) word acquisition process. Incidental acquisition of the words is only possible up to a point, _______, on account of their low frequency, they do not _______often enough in the L2 learning material.

Acquisition of new words from authentic L2 reading texts by means of strategies such as contextual deduction (演绎) is also not a _______for a number of reasons. There appears to be no _______to intentional learning of a great many new words in a relatively short period of time. The words to be learned may be _______in isolation or in context. Presentation in bilingual (双语的) word lists seems an _______shortcut because it takes less time than contextual presentation and yields excellent short term results. Long term memory, ________, is often disappointing so contextual presentation seems advisable.

Any suggestions on how to use this in educational contexts should be based on a systematic ________ of the two most important aspects of the L2 word learning problem, this is to say,   selecting the relevant vocabulary (which and how many words) and creating the best conditions for the acquisition process. This article sets out to ________a computer assisted word acquisition programme (CAVOCA) which tries to do exactly this: the programme operationalises current theoretical thinking about word acquisition, and its ________ are based on a systematic list of the vocabulary relevant for the target group. To ________its frequency, the programme was ________ in a number of experimental settings with a paired associated method of learning new words. The experimental results suggest that an approach combining the two methods is most advisable.

5 . Everyone knows what makes a good story. Our hero starts their journey as a flawed being. In scene after scene, they face challenges that push them down new paths. By the end of the talc, they overcome setbacks and become a better person in the process.

We love these plots in the novels we read but the principles of a good story offer much more than entertainment. Recent research shows that the narratives we tell ourselves about our lives can powerfully help us recover from stress. People who generate tales of struggling and turning over a new leaf from their own lives appear to have much better mental health. Professor Dan McAdams put forward this idea and discovered that whether someone can describe having had some control over events in their past is an important predictor of mental health. Another key theme involved is finding some kind of positive meaning after stressful events.

McAdams invited 14 and 15-year-olds to join in an experiment to write about their experiences of failure and success. Half of them were then given extra instructions to describe the ways they had made their success a reality and how the failure had changed them for the better. Eight weeks later, members of this group reported greater persistence and better grades in their schoolwork.

Exciting as these results are, some experts sound a few notes of caution. They worry that, hearing about the power of self-narratives, many people may feel they have to find a positive turning point in life. If they can’t, they could end up feeling guilty about having somehow “failed”.

Clearly, self-narratives aren’t the panacea. Nevertheless, if you hope for self-improvement, you can use the findings to good effect. By recognizing ourselves as the hero at the center of our own struggles, we can all become the author of our own destiny and change ourselves for the better.

7 . Slowness has been a sweeping trend in sustainability. Slow food celebrates local produce and traditional cooking methods; slow fashion is made with a focus on people and the planet. You may have even heard of the slow city, a campaign to restore local cultures and turn cities back to their natural environments.

Slow design developed from the larger slow movement. Although the term was only recently introduced, the idea of thoughtful design looks back to a time when buildings and furniture were made with great craftsmanship (手艺) and by hand-before the mass-produced throwaway furniture took over. You can think of the term “slow” as a celebration of timelessness: both the timelessness of a piece and the timelessness of the relationship between that piece and its owner.

One example of slow design today is what’s been dubbed the brown furniture revival (复兴). Brown furniture refers to the heavy wooden furnishings that were popular in your grandparents’ day but suddenly fell out of style at the turn of the century. Brown furniture is often associated with dark woods, such as trees like mahogany, walnut, and teak, that take decades to reach maturity and true craftsmanship to transform into functional pieces.

Today’s furniture industry is dominated by the $13.1 billion-and-growing global ready-to-assemble(RTA) furniture market. RTA furniture is usually constructed from low-quality fiberboard, which lasts a small part of traditional furniture’s lifespan (寿命).The weight of furniture landfilled in 2018 was 9. 7 million tons, 4. 5 times what was landfilled in 1960.

In a less direct way, the idea of timelessness also lends itself to a lower environmental impact. Besides their demonstrated physical durability, slow materials and design are meant to outlive trends and never be thrown out simply because they’re out of style.

As second-hand shopping becomes more appealing to today’s young generation-because of its low environmental impact and affordability-the brown furniture of yesteryear is making a comeback.

8 . It started with a bit of casual discomfort on the head, but after a week it had spread to the back of my neck, enough to lead me to my laptop. Annoying as it was, I was ________ to take up my doctor’s time with such a silly complaint and then have a wasted journey only to be informed that it would clear up by itself and that ________ would be of no use at all.

As soon as I’d tapped in ‘online self-diagnosis’, the search engine provided me with over 11.5 million results. And during the time normally spent in the clinic’s waiting room reading the Women’s Weekly, I was able to find a site that would provide a free ________ in the comfort of my chair, and with no need for an appointment,

I answered all the questions until I eventually reached a description exactly matching my ________. As I clicked on ‘More Information’, I was hit with what I’d never anticipated. The worst case scenario was complete hair loss. I couldn’t have been more ________.

I headed off to the doctor for what I thought would be a blood test but which turned out to be a valuable lesson in not ________ everything you read on the internet. It took him less than a minute to guess at and locate head lice (虱子). I was relieved to know that I would be ________ my hair, and horrified to know that it was being occupied.

I learnt my lesson, but for some the worry caused by ________ every ache has led to a new form of hypochondria (疑病症). Named ‘cyberchondria’ by the print media back in 2000, this particular condition has ________ greatly. Although most people’s main point of call is still the doctor’s surgery, it’s estimated that ________ worries are now the second most researched topic on the web. This is truly a serious concern when about 25%of the medical information online is thought to be ________.

Once upon a time, hypochondria required time and effort: you had to go to the library to research your diseases and ________ go through the books. Now it’s just a matter of a few clicks of a mouse. But while your doctor will make a diagnosis ________ your age, appearance and medical history, a search engine will rely simply on algorithms (算法). These come up with results graded according to popularity or numbers of key words. So the most highly ranked hits might actually be for very genuine disease, which are nonetheless extremely ________. One minute you think you’ve come down with the flu, the next you’re under attack from sub-tropical, flesh-eating bacteria. Time spent going to the doctor’s for ________ of mind suddenly seems fair enough.

9 . Every decision we make is arrived at through hugely complex neurological processing. Although it feels as though you have a choice, the action that you ‘decide’ to take is entirely directed by automatic neural activity. Brain imaging studies show that a person’s action can be predicted by their brain activity up to 10 seconds before they themselves become aware they are going to act. Multiple neuroscientific studies show that even those important decisions that feel worked out are just as automatic as knee-jerk reactions (膝跳反应) (although more complex).

Decision-making starts with the amygdala: a set of two almond-shaped nuclei (杏仁状核) buried deep within the brain, which generate emotion. The amygdala registers the information streaming in through our senses and responds to it in less than a second, sending signals throughout the brain. These produce an urge to run, fight, freeze or grab, according to how the amygdala values various stimuli.

Before we act on the amygdala’s signals, however, the information is usually processed by other brain areas, including some that produce conscious thoughts and emotions. Areas concerned with recognition work out what’s going on, those concerned with memory compare it with previous experiences, and those concerned with reasoning, judging and planning get to work on constructing various action plans. The best plan—if we are lucky—is then selected and carried out. If any of this process goes wrong, we are likely to hesitate, or do something silly.

The various stages of decision-making are marked by different types of brain activity. Fast (gamma)waves, with frequencies of 25 to 100 Hz, produce a keen awareness of the multiple factors that need to be taken into account to arrive at a decision. If you are trying to choose a sandwich, for instance, gamma waves generated in various cells within the ‘taste’ area of the brain bring to mind and compare the taste of ham, hummus, wholemeal, sourdough, and so on. Although it may seem useful to be aware of the full range of choice, too much information makes decision-making more difficult, so irrelevant factors get dismissed quickly and unconsciously.

After this comparison stage, the brain switches to slow-wave activity (12 to 30 Hz). This extinguishes most of the gamma activity, leaving just a single ‘hotspot’ of gamma waves which marks the chosen option.

Although there is no ‘you’ outside your brain to direct what it’s doing, you can help it to make good decisions by placing yourself in a situation which is likely to make the process run more smoothly. Doing something that is physically or mentally stimulating before making a decision will help your brain produce the initial gamma waves that generate awareness of the competing options. Getting over-excited, on the other hand, will prevent the switch to the slow brainwaves, making it much harder to single out a choice.
