Time is valuable but limit. There is a famous saying, “Time is life”, this shows the importance of time. When time had gone, it’ll never return. It’s a pity when many people make poor use of time. They spend their precious time oversleeping, drinking and hanging around. They don’t realize wasting time is equal with wasting their life. They always regret having made little achievement so far. However, we should form the habit of value time. Don’t put off what can be done today tomorrow. Laziness will not only bring us the failure, but also lead us to the road to poverty and even deaths.

There are many things we remember from our childhood—the games we played, the music we listened to...but what about earning pocket money? This was our first ever wage for completing tasks such as tidying our bedroom or sorting the laundry. Our reward was a handful of coins that we safely stored. 1.
There was a time when cash was the main currency for financial transactions (交易). These days, though, using credit cards, or making cashless payments, are the most convenient ways of paying. 2. Research has found that 84% of British parents currently give notes and coins to their children—usually 7 pounds a week as an allowance.
But banks predict that by 2028 only one in ten transactions will be with cash, and that is something today’s children will have to deal with. One issue is that children may not understand the value of cash because they never see it. 3. They either should find a new way to hand out pocket money, or needn’t bother to pay it at all.
Still, solutions are available. Giving children lessons at school about finance is important. 4. The trick is to go and get some coins so that children have the opportunity to interact with them. Besides, bank accounts for older children can be opened to give them cash cards to use. Whatever method a parent chooses to adopt, their children will get some idea of the value of pocket money. 5.
A. Parents face a dilemma too.
B. This, in turn, makes the buying much easier.
C. They have completely taken the place of cash.
D. So how do parents hand out pocket money at present?
E. But parents need to teach their kids that money doesn’t grow on trees!
F. But now, it seems that parents’ attitude to handing out cash is changing.
G. And parents are advised to get children started with money as young as possible.
According to a new study， teens focus on rewards and have a hard time learning to avoid punishment or consider the consequences of alternative actions.
University College London researchers compared how teens and adults learn to make choices based on the available information. They tracked the way in which 18 volunteers aged 12-17 and 20 volunteers aged 18-32 completed tasks in which they had to choose between abstract symbols.
Each symbol was consistently associated with a fixed chance of a reward, punishment, or no outcome. As the trial progressed ， participants learned which symbols were likely to lead to each outcome and adjusted their choices accordingly. Teens and adults were equally good at learning to choose symbols associated with reward， but teens were less good at avoiding symbols associated with punishment. Adults also performed significantly better when they were told what would have happened if they had chosen the other symbol after each choice， while teens did not appear to take this information into account.
“From this experimental lab study we can draw conclusions about learning during the teen years. We find that teens and adults learn in different ways， something that might be relevant to education," said lead author Dr. Stefano Palminteri. " Unlike adults, teens are not so good at learning to adjust their choices to avoid punishment. This suggests that incentive systems based on reward rather than punishment may be more effective for this age group. Additionally, we found that teens did not learn from being shown what would have happened if they made alternative choices."
To interpret the results, the researchers developed computational models of learning and ran simulations （模拟）applying them to the results of the study. The first was a simple model, one that learned from rewards, and the second model added to this by also learning from the option that was not chosen. The third model was the most complete and took the full context into account, with equal weight given to punishment avoidance and reward seeking. For example, obtaining no outcome rather than losing a point is weighted equally to gaining a point rather than having no outcome.
Comparing the experimental data to the models, the team found that teens" behavior followed the simple reward-based model while adults" behavior matched the complete, contextual model. “Our study suggests that teens are more receptive to rewards than they are to punishments of equal value, ” said senior author Dr. Sarah-Jayne Blakemore. “As a result, it may be useful for parents and teachers to frame things in more positive terms.”

A.adults made choices faster than teens

4.According to the writer, which of the following statements works best for teens?
A.“If you insist on doing things in this way， you will lose ten points. "
B.“If we had talked about this earlier， you wouldn’t have made the mistake. "
C.“ If you hand in your assignment ahead of time， you will get an extra bonus."
D.“If you want to approach a problem differently ， you can talk to your parents. "
Pigeons in London have a bad reputation. Some people call them flying rats. And many blame them for causing pollution with their droppings. But now the birds are being used to fight another kind of pollution in this city of 8.5 million.
“The problem for air pollution is that it’s been largely ignored as an issue for a long time,” says Andrea Lee, who works for the London-based environmental organization Client Earth. “People don’t realize how bad it is, and how it actually affects their health.” London’s poor air quality is linked to nearly 10,000 early deaths a year. Lee says, citing(引用)a report released by the city manager last year. If people were better informed about the pollution they’ re breathing, she says, they could pressure the government to do something about it.
Nearby, on a windy hill in London’s Regent’s Park, an experiment is underway that could help—the first week of flights by the Pigeon Air Patrol. It all began when Pierre Duquesnoy, the director for DigitasLBi, a marketing firm, won a London Design Festival contest last year to show how a world problem could be solved using Twitter. Duquesnoy, from France, chose the problem of air pollution.
“Basically, I realized how important the problem was,” he says. “But also I realized that most of the people around me didn’t know anything about it.” Duquesnoy says he wants to better measure pollution, while at the same time making the results accessible to the public through Twitter.
“So”, he wondered, “how could we go across the city quickly collecting as much data as possible?” Drones were his first thought. But it’s illegal to fly them over London. “But pigeons can fly above London, right?” he says. “They live—actually, they are Londoners as well. So, yeah, I thought about using pigeons equipped with mobile apps. And we can use not just street pigeons, but racing pigeons, because they fly pretty quickly and pretty low.”
So it might be time for Londoners to have more respect for their pigeons. The birds may just be helping to improve the quality of the city’s air.
1.What can we infer about London’s air quality from Paragraph 2?
A.Londoners are very satisfied with it.
B.The government is trying to improve it.
C.Londoners should pay more attention to it.
D.The government has done a lot to improve it.
2.Duquesnoy attended the London Design Festival to _________.
A.entertain Londoners. B.solve a world problem.
C.design a product for sale. D.protect animals like pigeons.
3.Why did Duquesnoy give up using drones to fly across London?
A.Because they are too expensive. B.Because they fly too quickly.
C.Because they are forbidden. D.Because they fly too high.
4.Which can be the best title for the text?
A.Clean air in London. B.London’s dirty secret.
C.London’s new pollution fighter. D.Causes of air pollution in London.
