Eating a diet high in processed（经过加工的） food increases the risk of depression（抑郁）, research suggests. What's more, people who ate plenty of vegetables, fruit and fish actually had a lower risk of depression, the University College London team found.
Data on diet among 3,500 middle-aged civil servants were compared with their emotional state five years later, a British journal reported. They split the participants（参与者） into two types of diet--those who ate a diet largely based on whole food，which includes lots of fruit, vegetables and fish，and those who ate a mainly processed food diet, such as sweetened desserts, fried food, processed meat，refined（精制的） grains and high fat dairy products After accounting for factors such as gender, age, education, physical activity, smoking habits and chronic(慢性的) diseases, they found a significant difference in the future depression risk with the different diets.
Those who ate the most wholefood（全天然食物） had a 26% lower risk of future depression than those who ate the least wholefood. By contrast, people with a diet high in processed food had a 58％ higher risk of depression than those who ate a diet low in processed foods.
Study author Dr. Archana Singh Manoux pointed out there was a chance that the finding could be explained by lifestyle factor they had not accounted for.（解释原因） He also pointed in a paper that a Mediterranean(地中海) diet was associated（有关） with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood （可能）of you eating a Mediterranean diet is not very high.
Dr．Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health.
He added people's diets were becoming increasingly unhealthy. The UK population is consuming （消费）less nutritious, fresh produce and more saturated（饱和） fats and sugars.

【解析】
试题分析：这篇文章通过研究表明使用经过高加工的食物能增加患抑郁症的风险，我们的饮食与我们的精神健康也有密切的联系。
1.细节题。由第一段第一句Eating a diet high in processed（经过加工的） food increases the risk of depression（抑郁）, research suggests.研究表明，食用经过高加工的食物会增加患抑郁症的风险，后文详细介绍了两者之间的实验对比及影响。可知，本文主要讲的是加工食品和抑郁症之间的关系。故选B
2.细节题。由第四段第二句He also pointed in a paper that a Mediterranean(地中海) diet was associated（有关） with a lower risk of depression, but the problem with that is if you live in Britain, the likelihood （可能）of you eating a Mediterranean diet is not very high.
Dr. Archana Singh Manoux在论文中指出，患抑郁症的风险较低和地中海的食物有关，但问题是，如果你居住在英国，你食用地中海食物的可能性不是非常高，故对大多数英国人来说，有地中海饮食是困难的。故选A。文中并未说明地中海食物是世界最健康的，没有比较关系。
3.细节题。由第五段Dr．Andrew McCulloeh, chief executive of the Mental Health Foundation, said, this study adds to an existing body of solid research that shows the strong links between what we eat and our mental health. Dr．Andrew McCulloeh这项研究表明我们所吃的和我们的心理健康之间有着紧密的关系。故选A
4.主旨题。作者写本文的目的是想鼓励人们应少食用高加工食品。文章整个围绕加工食品会增加人们患抑郁症的风险这个主题来行文，所以答案中必须提到加工食品的相关论点。故选C
考点：说明文
点评：本文属于科普类文体，对于此类文章的阅读，由于出现的人物较多同时会有很多的生词汇，对解题会存在一定的难度。建议在答题时，注意文章的第一段和每段的第一句话，往往就是主旨段或句，把握好文章说明的实质内容，对于细节题可以到文章中找相对应的地方，对于主旨题需要包含文章主要说明的主题中的关键字，这样才能有效的答题。
For photographers lacking training, experience and even the ability to click a shutter button, they produce remarkable pictures．Under the sea, deep in the woods and high in the sky, furry, feathery and leathery-skinned creatures are opening up vistas（远景）by taking cameras where no human can go．
This is the world of animal-borne imagine celebrated last month at a conference sponsored(supported) by the National Geographic Society for the 20th anniversary of its Crittercam, the device that started it all．
Since its debut（首次公开露面）in 1987 on the back of a turtle, the Crittercam and similar devices developed by others have grown smaller and more powerful．
“It’s more than just a camera now,” said Greg Marshall, the marine biologist and now filmmaker who invented the Crittercam．“We are now including more instruments to gather more data while at the same time reducing everything in size．”
The idea of attaching video cameras to animals came to Mr．Marshall in 1986 on a dive off Belize when a shark apporached him．When the animal quickly turned away, he noticed a shark with a sucker fish on its belly．He came up with the idea that putting a camera in place of the sucker fish would allow people to witness the shark’s behavior without disturbing it．
Crittercams have been attached to sharks, sea lions and other marine animals, and, more recently, to land animals．
Birds are a new addition, Mr．Marshall said．Dr．Christian Rutz of Oxford recently reported on tiny cameras called feathercams that monitor the crows in the South Pacific．It has discovered that crows are smarter than anyone knew they not only use twigs（嫩枝）and grass stems as tools to root out food, but they also save their favorite tools to use again．
Tracey L．Rogers, director of the Australian Marine Mammal Research Center in Sydney, said crittercam was a powerful tool in her work with leopard seals（豹斑海豹）in Antarctica．“In studying animals,” Dr．Rogers said at the meeting, “you want to see how our animal models align（与……一致）with reality．With a camera, you actually see what they do．You don’t have to guess．”

Work your brain!
Between 2 and 3 pounds of wonder, it controls everything we say, do or think, who we are and what we care about. The way we walk or laugh or figure out things. What we like and the talents we possess. How we see and talk and run and jump and process our food.
The brain uses 20 percent of our body’s oxygen and 20 percent of its blood. Somewhere within its protein, fat, 100,000 miles of blood vessels and 100 billion nerve cells, it helps us remember where we put our gym shoes. Change our temperature so we don’t die because of the heat or cold. Speed us up or slow us down. Help us choose between orange juice or orangeflavored drinks.
Its complexity are stunning, far beyond anything most of us can imagine. To keep this work of art as polished as possible we need to eat right, exercise and keep mentally stimulated. Good nutrition helps brain cells communicate with each other. Exercise stimulates a hormone in our brain that improves memory. Mental stimulation keeps you sharp even as you age.
“It’s very important that we tell people to be physically active and mentally active,” said neurologist Malcolm Stewart.“People cannot stop aging, but you’re able to reduce the damage; you’re able to keep the function up.”
Following are Dr. Stewart’s advice for improving brain health：
|
Nutrition |
Avoid fast food. Follow the old adage(格言): For breakfast, eat like a king; for lunch, like a queen; for supper, like a beggar. |
|
Exercise |
Do a combination of stretching aerobic and muscle strengthening every day. |
|
Mental games |
Try to have a sense of hope about the future. Do puzzles. Listen to music. Reach out to others to make their lives better. |
