Recent findings have 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 （感知） of the food in front of us.A new study suggested that our shortterm memory may also 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 difference 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 merely 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 2016 study，for instance，people who drank the same 380 calorie milkshake on two separate occasions produced different levels of hunger-related hormones （荷爾蒙），depending on whether the shake's label said it contained 620 or 140 calories.Moreover，the participants reported feeling more fill when they thought they'd consumed a higher-caloric shake.

1．More than half of the food produced in Canada goes to waste．A shocking new study has shown that the level of food waste is far worse than previously thought，at 58%．Of that，about 85% of food waste is due to food processors．This differs from earlier studies，which criticized families for driving food waste and said they were responsible for 51% of food waste．
The study was carried out by Martin Hooch，the leading expert on food waste and the author of several previous studies on the subject．Reflecting on the study's findings，Hooch said，"It means stopping criticizing consumers．Sure，consumers are part of the problem，but they're not the problem．"
In the past，Hooch didn't master good data，particularly from the private factories，but relied on numbers collected by the food industry for purposes other than tracking（追蹤） waste．This time，however，Hooch worked directly with companies at all stages along the food production chain and interviewed over 700 experts in the industry．Clearly he found it hard to believe what he was seeing．
This is what they found：Food processing causes 34% of food waste．This is followed by production，which causes 24%．Next is manufacturing at 13%，then hotels and restaurants at 9%．Families cause only 14%，and market sales 6%．This should be a serious wake-up call for Canadians who would do well to examine their own food supply chains．Food waste is costly，not only in terms of dollars wasted，but also in resources like land，water，and so on．To be using these resources and wasting the product is totally irresponsible and unnecessary．
To make matters worse，when food is thrown into rubbish cans，it produces methane，a greenhouse gas 30 times more powerful than carbon dioxide （CO2）．At Canada's rate of food waste，that's like adding 12 million cars to the road．It seems that the food industry needs redesigning．Therefore，let's hope the government takes action．
（1）What did earlier studies say about food waste in Canada？
A．Food waste was better than expected．
B．Food went bad when it was processed．
C．Most of the food was wasted on purpose．
D．Families were to blame for food waste．
（2）How did Hooch do his study on food waste this time？
A．By studying data from the industry．
B．By tracking the whole production chain．
C．By collecting advice from experts worldwide．
D．By drawing a conclusion from the previous studies．
（3）Why does food waste have an effect on the environment？
A．Because it is harmful to the trees．
B．Because it pollutes the soil around it．
C．Because it gives off unpleasant smells．
D．Because it produces more greenhouse gas．
（4）What is the main idea of the text？
A．Canadians don't like to save food for future．
B．More than half of the food is wasted in Canada．
C．Families are mainly responsible for food waste．
D．The food industry is better redesigned in Canada．發(fā)布：2024/12/5 0:0:1組卷：9引用：5難度：0.5 -
