Eating foods high in trans-fats(fats present in artificial form in industrially-produced cakes and fast food...) and saturated (飽和的) fats increases the risk of depression, according to a Spanish study, confirming previous studies that linked “junk food” with the disease. Researchers also showed that some products, such as olive oil, can fight against the risk of mental illness.
Authors of the wide-reaching study, from the universities of Navarra and Las Palmas, followed and analyzed the diet and lifestyle of over l2,000 volunteers over six years. When the study began, none of the participants had been diagnosed with depression; by the end, 657 of them were new sufferers.
“Participants with an increased consumption of trans-fats presented up to a 48 percent increase in the risk of depression when they were compared to participants who did not consume these fats,” the head study author said. “The more trans-fats were consumed, the greater harmful effect they produced in the volunteers.”
The research team found, at the same time, that after assessing the effect of polyunsaturated fats made up of larger amounts of fish and vegetable oils and olive oil, these products are associated with a lower risk of suffering depression.
The report, published in the online journal PLOS ONE, noted the research was performed on a European population that enjoys a relatively low intake of trans-fats—making up only 0.4 percent of the total energy taken in by the volunteers. “Despite this, we observed an increase in the risk of suffering depression of nearly 50 percent,” said researcher Miguel Martinez. “On this basis we think it of great importance to take this effect into account in countries like the United States, where the percentage of energy derived from these fats is around 2.5 percent.”
The report pointed out that the current number of depression sufferers in the world is around l50 million people, and has increased in recent years. This rise is attributable, according to the authors, “to great changes in the sources of fats consumed in Western diets, where we have replaced certain types of beneficial fats in nuts, vegetable oils and fish with the saturated and trans-fats found in meats, butter and other products such as mass-produced cakes and fast food.”

Is there anything more important than health? I don’t think so. “Health is the greatest wealth，” wise people say. You can’t be good at your studies or work well when you are ill.
If you have a headache, toothache, backache, earache or bad pain in the stomach, if you complain of a bad cough, if you run a high temperature and have a bad cold, or if you suffer from high or low blood pressure, I think you should go to the doctor. The doctor will examine your throat, feel your pulse, test your blood pressure, take your temperature, sound your heart and lungs, test your eyes, check your teeth or have your chest X-rayed. After that, he will advise some treatment, or some medicine. The only thing you have to do is to follow his advice.    
Speaking about doctor’s advice, I can’t help telling you a funny story. An old gentleman came to see the doctor. The man was very ill. He told the doctor about his weakness, memory loss and serious problems with his heart and lungs. The doctor examined him and said there was no medicine for his disease. He told his patient to go to a quiet place for a month and have a good rest. He also advised him to eat a lot of meat, drink two glasses of red wine every day and take long walks. In other words, the doctor advised him to follow the rule: “Eat with pleasure, drink with pleasure and enjoy life as it is.” The doctor also said that if the man wanted to be well again, he shouldn’t smoke more than one cigarette a day. A month later the gentleman came into the doctor’s office. He looked cheerful and happy. He thanked the doctor and said that he had never felt a healthier man.“ But you know, doctor,” he said, “it’s not easy to begin smoking at my age.”

Lots of kids go through times when they’d like to change their hair. Often, it’s girls who are most concerned(關(guān)心的), but boys may be interested in how their hair looks, too. Sometimes hair will change as you get older----all by itself----when you go through puberty(青春期).
Maybe it used to be lighter and now it’s darker. Or maybe it’s oilier than it used to be, and now you need to wash it more. It’s also normal, as you’re getting older, to notice your appearance more often. You might suddenly decide you want a hairstyle like other kids at school have. But some styles and looks require chemical treatments and long hours in the chair at the hair salon. Some people dye(染)their hair a different color, get a bunch of braids(辮子），or make their hair straight when it’s curly（卷曲). Are these treatments OK for kids? That’s something you should discuss with your parents. At any age, any chemical or heat applied to(應(yīng)用于) the hair can damage the hair or cause it to break off.
Any styling that pulls hard on the hair can also hurt the scalp(頭皮) or cause hair loss. Styling tools, such as curling irons and straightening irons, get very hot and can cause burns. And chemicals used to color, curl, or straighten hair can be very harmful if they get into your eyes or onto your skin.
小題1:The word “kid”in this passage refers to ____________.

Carrot juice, because of its many healthy benefits, is commonly called the "magic juice". It has been found that adding carrot juice to people’s diets greatly improves their health. And its delicious taste makes it popular with all members of the family as a beverage.
Carrot juice is one of the richest sources of vitamin A that can be used in the daily diet. Lack (缺乏) of vitamin A can cause dryness and damage to the skin, nails and hair. Drinking carrot juice to increase the vitamin A in the diet is said to be good for many parts of the body, including the bones and teeth.
Drinking carrot juice is thought to be extremely helpful to the liver (肝臟), because vitamin A helps to clean the liver and reduce fat in it. And it is suggested that drinking carrot juice should be done regularly, rather than just from time to time.
Drinking carrot juice is also thought to improve the eyesight because of the vitamin A in the juice. Lack of vitamin A can lead to night blindness, which can be very dangerous, especially when the person is driving a car. An easy way to find out if you are lacking in vitamin A is to walk from a bright room into a dark room. Your eyes may have some trouble in getting used to the change of light if you are lacking in vitamin A.

Bungee jumping is an activity about jumping from a tall structure while connected to a large elastic cord(有彈性的繩子). The tall structure is usually a fixed object, such as a building, bridge or crane; but it is also possible to jump from a movable object, such as a hot-air balloon or helicopter, that has the ability to stay over one place on the ground; fixed-wing aircraft are unsuitable because they only stay high when moving quickly forward.
When the person jumps, the cord stretches to absorb (吸收)the energy of the fall, then the jumper flies upwards again as the cord jumps back. The jumper oscillates(擺動)up and down until all the energy is used up.
The word bungee first appeared around 1930 and was the name for a rubber eraser. The first modern bungee jumps were made on 1 April 1979 from the 250-foot Clifton Suspension Bridge in Bristol, by David Kirk, Chris Baker and Alan Weston of the Dangerous Sports Club. The jumpers continued with jumps in the US from the Golden Gate and Royal Gorge bridges, spreading the concept worldwide. By 1982 they were jumping from mobile cranes and hot-air balloons. Later they put on commercial(商業(yè)的)shows, which began in 1986.
As with any sport, injuries can still happen, and there have been deaths. A relatively common mistake in the cases that may cause death is to use a cord that is too long. The cord should be fully shorter than the height of the jumping place to allow it room to jumper either starts to slow down or keeps speeding up depending upon the speed of falling.
小題1:Which of the following is NOT suitable for bungee jumping?
A．The fixed-wing aircraftB．The helicopter
C．The hot-air balloonD．The mobile crane
小題2:In the second paragraph, the author tells_________________.
A．who suits bungee jumping
B．the principle of bungee jumping

小題3:According to the last paragraph, the safety of the jumpers depends mainly on________.
A．the weight of the jumper
B．the height of the jumping place
C．the length of the cord
D．the speed of the falling
小題4:The purpose of writing this passage is to__________.
A．teach people how to carry out a bungee jumping
B．remind people of the danger of bungee jumping
C．a(chǎn)dvise people not to take the risk of bungee jumping
D．introduce some knowledge about bungee jumping

We all know that everyone becomes a little more forgetful as they get older, but men’s minds decline more than women’s, according to the results of a worldwide survey.
General differences seem to be natural in male and female brains: Men are better at maintaining and dealing with mental images (useful in mathematical reasoning and spatial skills), while women tend to excel be good at recalling information from their brain’s files. Many studies have looked for a connection between sex and the amount of mental decline people experience as they age, but the results have been mixed.
Some studies found more age-related decline in men than in women, while others saw the opposite or even no relationship at all between sex and mental decline.
Those results could be improper because the studies involved older people, and women live longer than men: The men tested are the survivors, “so they’re the ones that may not have shown such cognitive(認(rèn)知的) decline,” said study team leader Elizabeth of the University of Warwick in England.
Scientists surveyed completed four tasks that tested sex-related cognitive skills: matching an object to its rotated form, matching lines shown from the same angle, typing as many words in a particular category as possible in the given time, e.g. “object usually colored gray”, and recalling the location of objects in a line drawing. The first two were tasks at which men are usually good; the latter are typically dominated by women. Within each age group studied, men and women performed better in their separate categories on average. And though performance declined with age for both genders, women showed obviously less decline than men overall.
小題1:According to the passage, which of the following can NOT be typed into the same category?
A．cloudB．sheepC．treesD．goose
小題2:Which of the following statements is true according the article? _______
A．Men do better than women when it comes to learning English.
B．Women stand out at remembering people’s names.
C．Women do well in dealing mathematic problems.
D．Men excel at typing as many words as possible in the given time.
小題3:One important factor that affects the correctness of the results is that ________.
A．women live longer than men
B．people surveyed are all old
C．the old men tested may not have shown such cognitive decline
D．people taking part in this test came from all over the world
小題4:The author aims to tell us that _________.
A．women’s minds perform better than men’s
B．men’s minds decline more with age
C．everyone becomes a little more forgetful as they get older
D．a(chǎn) survey on human’s mind decline was done recently

For many years, I had a belief that my suffering was due to my size. I believed that when the weight disappeared, it would take old wounds, hurts, and rejections with it.
Many weight－conscious people also mistakenly believe that changing our bodies will fix everything. Perhaps our worst mistake is believing that being thin equals being loved，being special, and being cherished. We fantasize（幻想） about what it will be like when we reach the long－awaited goal. We work very hard to realize this dream. Then, at last, we find ourselves there.
But we often gain back what we have lost. Even so, we continue to believe that next time it will be different. Next time, we will keep it off. Next time, being thin will finally fulfill its promise of everlasting happiness, self－worth, and, of course, love.
It took me a long while to realize that there was something more for me to learn about beauty. Beauty standards vary with culture. In Samoa a woman is not considered attractive unless she weighs more than 200 pounds. More importantly, if it’s happiness that we want, why not put our energy there rather than on the size of our body? Why not look inside? Many of us strive hard to change our body, but in vain. We have to find a way to live comfortably inside our body and make friends with and cherish ourselves. When we change our attitudes toward ourselves, the whole world changes.
小題1:The passage tries to highlight the importance of ________.
A．body size
B．a(chǎn)ttitudes toward life
C．culture difference
D．different beauty standards
小題2:What does the word “everything” in paragraph 2 mean?
A．All the problems.B．All the properties.
C．The whole world.D．The absolute truth.
小題3:What can be inferred about the author?
A．The author is a Samoan.
B．The author succeeded in losing weight.
C．The author has been troubled by her/ his weight.
D．The author probably got wounded in wars or accidents.
小題4:According to the author, what is the common view of those who have lost some weight first and gained it back later?
A．They feel angry about the regained weight.
B．They are indifferent to the regained weight.
C．They feel optimistic(樂觀的) about future plans on weight control.
D．They think they should give up their future plans on weight control.
