You should decide on the best choice and mark the corresponding letter on Answer Sheet 2 with a single line through the centre.
Passage One
Questions 56 to 60 are based on the following passage.
In recent years, a growing body of research has shown that our appetite and food intake are influenced by a large number of factors besides our biological need for energy, including our eating environment and our perception of the food in front of us.
Studies have shown, for instance, that eating in front of the TV (or a similar distraction) can increase both hunger and the amount of food consumed. Even simple visual cues, like plate size and lighting, have been shown to affect portion size and consumption.
A new study suggested that our short-term memory also may play a role in appetite. Several hours after a meal, people's hunger levels were predicted not by how much they’d eaten but rather by how much food they'd seen in front of them—in other words, how much they remembered eating.
This disparity (盖弃）suggests the memory of our previous meal may have a bigger influence on our appetite than the actual size of the meal, says Jeffrey M. Brunstrom, a professor of experimental psychology at the University of Bristol.
"Hunger isn't controlled solely by the physical characteristics of a recent meal. We have identified an independent role for memory for that meal，" Brunstrom says. "This shows that the relationship between hunger and food intake is more complex than we thought."
These findings echo earlier research that suggests our perception of food can sometimes trick our body’s response to the food itself. In a 2011 study, for instance, people who drank the same 3S0-calorie (卡路里）milkshake on two separate occasions produced different levels of hunger-related hormones （荷尔蒙），depending on whether the shake’s label said it contained 620 or 140 calories. Moreover, the participants reported feeling more full when they thought they'd consumed a higher-calorie shake.
What does this mean for our eating habits? Although it hardly seems practical to trick ourselves into eating less, the new findings do highlight the benefits of focusing on our food and avoiding TV and multitasking while eating.
The so-called mindful-eating strategies can fight distractions and help us control our appetite, Brunstrom says.

Passage Two
Questions 61 to 65 are based on the following passage.
As a society we might want to rethink the time and money spent on education, so that these resources can benefit a greater percentage of the population. Ideally, both high schools and colleges can prepare individuals for the ever-changing roles that are likely to be expected of them.
High school degrees offer far less in the way of preparation for work than they might, or than many other nations currently offer, creating a growing skills gap in our economy. We encourage students to go on to college whether they are prepared or not, or have a clear sense of purpose or interest, and now have the highest college dropout rate in the world.
We might look to other countries for models of how high schools can offer better training, as well as the development of a work ethic (勤奋工作的美德）and the intellectual skills needed for continued learning and development. I recommend Harvard's 2011 "Pathways t
o Prosperity" report for more attention to the "forgotten half" (those who do not go on to college) and ideas about how to address this issue.
Simultaneously, the liberal arts become more important than ever. In a knowledge economy where professional roles change rapidly and many college students are preparing for positions that may not even exist yet, the skill set needed is one that prepares them for change and continued learning.
