5．Earlier this year，my oldest daughter got braces（矫正器）on her teeth，and let's just say she did not go quietly into that dentist's chair．Fear and hate pretty much describe the days leading up to her first appointment．
So when she finally walked out with shiny teeth，a sore（疼痛的）mouth and a broken spirit，I told her I was proud of her and took her to Ben &Jerry's for an ice cream reward．Two weeks later，we returned to the scene of the crime．The dentist spent about 45seconds checking her teeth before sending her on her merry way．Before I could start the car，she was placing her ice cream order．She was shocked when I told her that she wasn't going to get a reward every time we get her teeth checked．
Clearly，she's not alone．According to some parenting experts，kids are easily addicted to a benefit-producing system of parental rewards and bribes-it's not all ice creams，candies and cool toys．Some parents are offering their children prizes to just let them sit down and behave in a restaurant-or sleep in their own beds-or score a goal in the next soccer game．
While the experts agree that occasional awards are okay，the danger lies in the system's overuse．Kids quickly gain a sense of entitlement（应得的权利），where they come to expect a big reward for every good thing that they do，no matter how small．To keep things in check，experts say parents should reduce the number of rewards they offer，make sure rewards match the behavior and explain the real benefits of behaving for the sake of behaving．
Have you used bribery or a reward system with your kids？Was it successful？Do your kids expect more because of that system？

30．Similar to the author's daughter，childrenB．
A．are often troubled by bad teeth，
B．expect more reward from their parents．
C．are afraid to visit a dentist．
D．receive certain rewards when becoming i11．
31．Misguided by the parental reward system，children easily thinkC．
A．their parents must be far richer than others'
B．they can be successful as long as they work hard．
C．they should benefit from their every desired behavior．
D．their parents will feel happy when they behave well．

12．Sustainable development is applied to just about everything from energy to clean water and economic growth，and as a result it has become difficult to question either the basic assumptions behind it or the way the concept is put to use．This is especially true in agriculture，where sustainable development is often taken as the sole measure of progress without a proper appreciation of historical and cultural perspectives．
To start with，it is important to remember that the nature of agriculture has changed markedly throughout history，and will continue to do so．Medieval agriculture in northern Europe fed，clothed and sheltered a predominantly rural society with a much lower population density than it is today．It had minimal effect on biodiversity，and any pollution it brought about was typically localized．In terms of energy use and the nutrients captured in the product it was relatively inefficient．
Contrast this with farming since the start of the industrial revolution．Competition from overseas led farmers to specialize and increase yields．Throughout this period food became cheaper，safe and more reliable．However，these changes have also led to habitat loss and to diminishing biodiversity．
What's more，demand for animal products in developing countries is growing so fast that meeting it will require an extra 300million tons of grain a year by 2050，yet the growth of cities and industry is reducing the amount of water available for agriculture in many regions．
All this means that agriculture in the 21st century will have to be very different from how it was in the 20th．This will require complete thinking．For example，we need to move away from the idea that traditional practices are inevitably more sustainable than new ones．We also need to abandon the notion that agriculture can be"zero impact"．The key will be to abandon the rather simple and static measures of sustainability，which centre on the need to maintain production without increasing damage．
Instead we need a more dynamic interpretation，one that looks at the pros and cons of all the various way land is used．There are many different ways to measure agricultural performance besides food yield：energy use，environmental costs，water purity，carbon footprint and biodiversity．It is clear，for example，that the carbon of transporting tomatoes from Spain to the UK is less than that of producing them in the UK with additional heating and lighting，but we do not know whether lower carbon footprints will always be better for biodiversity．
What is crucial is recognizing that sustainable agriculture is not just about sustainable food production．

57．How do people often measure progress in agriculture？C
A．By its productivity
B． By its impact on the environment
C．By its sustainability
D．By its contribution to economic growth
58．What does the author think of traditional farming practices？C
A．They have remained the same over the centuries
B．They have not kept pace with population growth
C．They are not necessarily sustainable
D．They are environmentally friendly
59．What will agriculture be like in the 21st century？A
A．It will go through radical changes
B．It will supply more animal products
C．It will abandon traditional farming practices
D．It will cause zero damage to the environment
60．What is the author's purpose in writing this passage？D
A．To remind people of the need of sustainable development
B．To suggest ways of ensuring sustainable food production
C．To advance new criteria for measuring farming progress
D．To urge people to rethink what sustainable agriculture is．
