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 (肝脏), 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.
How can you make carrot juice? Wash some carrots well in cold water. Scrape (刮) them lightly, but do not peel them, as this will take away valuable vitamins and minerals that lie close to the skin.

Short people, studies have shown , are more likely to have a stroke , suffer from high blood pressures and heart disease and be bullied in school .
Now, researchers report that short people—at least in the past—were also more likely to die at a younger age than their taller peers.
Their study, published in the Journal of Epidemiology (流行病学) and Community Health , found that short bones have something to do with short life for more than 1,000 years. The conclusion was based on 490 sets of adult skeletal(骨架) remains from an archaeological(考古学的) site in northeastern England , YC dating from the 9th century to about 1850 .
About 55% of men and 73% of women died before the age of 45, and 39% of men and 56% of women died before age 30. The risk of death before age 30 declined as bone length increased.
“This study provides evidence from an archaeological sample that long bone length is connected with age at death—those with smaller bones tend to die younger,” according to Dr. D.J. Gunnell of the university of Bristol in the UK and colleagues .
While it is not clear why short stature(身材) might be linked to earlier death , the researchers point out that height is an indicator of childhood nutrition, which may have long-lasting effect on health .
“Mechanism (身体结构) for height-mortality(死亡) associations in the past may differ from those today , for example , short stature may have increased the risk of death in childbirth and this may explain the higher risk of premature(未成熟的) mortality in women,” Gunnell and colleagues write .
“However, short bones, it would appear, have always been a marker of a short life,” the authors conclude.
小题1:The title of the passage should be .

A．Short people and their taller peers

B．Men and women

C．Short stature and short life

D．Long life and short life

小题2:“An indicator” in Paragraph 6 means .

Since 1950, the amount of information about the nutrition of food has increased by nearly 900 percent. Besides this fact, obesity has risen by 214 percent and nearly two out of every three adults in America are overweight or obese. Being overweight is not only an appearance problem, and it also increases the risk of various diseases including diabetes, sleep disorder and cancer.
With so much nutritional knowledge easy to find, we cannot simply ignore our present obesity epidemic(流行病). We know that fruits and vegetables are rich in vitamin. Though we are overweight, many of us choose junk food over healthy food out of habits. One explanation for our strong desire for junk food is that we learn to connect junk food with positive feelings when we are young, and changing this attitude requires a huge amount of confidence and determination. Fortunately, new research published in May 2012 has shown a simple and accessible way to make healthier food choices- the one that doesn’t rely on great determination.
The research was based on two separate studies and it was carried out by T. Bettina Cornwell of the University of Oregon and Anna R. McAlister of Michigan State University. In the first study, 60 adults between the ages of 19 and 23 were questioned about the role of food and drinks. The survey tells us that adults prefer sweetened drinks with high-calorie, salty foods, to sweetened drinks with vegetables.
In the second study, 75 children between the ages of 3 and 5 were gathered for some experiments including drinks served with vegetables. The preschooler experiments were carried out under different situations and on different days. The researchers found that the children chose to take more green vegetables when they were served with water instead of a sweetened drink.
According to Cornwell, children learn to connect high calorie, sugary drinks such as cola, with high fat foods such as French fries, from a very early age. McAlister adds that early taste development appears to play an important role in food choices later in life. Meals served at home and meals offered at restaurants, set the stage for this idea and for the preference to choose junk food over healthy food, when beginning to take sweetened drinks.
“Our taste preferences are heavily influenced by regularly eating particular food and drinking particular drink,” states Cornwell. “If the drink on the table goes against both adults and children eating their vegetables, then perhaps it is time to change that drink… and to serve water with all meals. Restaurants could easily use water as free drink for children’s meals and charge extra money for other drinks.” Both McAlister and Cornwell are confident that serving water with meals could effectively reduce the nation’s obesity rates, diabetes rates and ever rising healthcare costs.

For a while, my neighborhood was taken over by an army of joggers(慢跑的人). They were there all the time: early morning, noon, and evening. There were little old ladies in gray sweats, young couples in Adidas shoes, middle-aged men with red faces. “Come on!” My friend Alex encouraged me to join him as he jogged by my house every evening. “You’ll feel great.”
Well, I had nothing against feeling great and if Alex could jog every day, anyone could. So I took up jogging seriously and gave it a good two months of my life, and not a day more. Based on my experience, jogging is the most overvalued form of exercise around, and judging from the number of the people who left our neighborhood jogging army. I’m not alone in my opinion.
First of all, jogging is very hard on the body. Your legs and feet are a real pounding（沉重的脚步） running down a road for two or three miles. I developed foot, leg, and back problems. Then I read about a nationally famous jogger who died of a heart attack while jogging, and I had something else to worry about. Jogging doesn’t kill hundreds of people, but if you have any physical weaknesses, jogging will surely bring them out, as they did with me.
Secondly, I got no enjoyment out of jogging. Putting one foot in front of the other for forty-five minutes isn’t my idea of fun. Jogging is also a lonely pastime. Some joggers say, “I love being out there with just my thoughts” Well, my thoughts began to bore me, and most of them were on how much my legs hurt.
And how could I enjoy something that brought me pain? And that wasn’t just the first week—it was practically every day for two months. I never got past the pain level, and pain isn’t fun. What a cruel way to do it! So many other exercises, including walking, lead to almost the same results painlessly, so why jog?
I don’t jog any more, and I don’t think I ever will. I’m walking two miles three times a week at a fast pace, and that feels good. I bicycle to work when the weather is good. I’m getting exercise, and I’m enjoying it at the same time. I could never say the same for jogging, and I’ve found a lot of better ways to stay in shape.
小题1:From the first paragraph, we learn that in the writer’s neighborhood _________.

A．Jogging became very popular

B．People jogged only during the daytime

C．Alex organized an army of joggers

D．Jogging provided a chance to get together

小题2:The underlined word “them”（Paragraph 3） most probably refers to _____．

A．heart attacks	B．back problems
C．hundreds of people	D．physical weaknesses

小题3:From the writer’s experience, we can conclude that_____

A．Jogging can help people keep fit

B．Many physical problems result from jogging

C．Not everyone enjoys jogging

D．Jogging makes people feel greater

Eating foods high in trans-fats(fats present in artificial form in industrially-produced cakes and fast food...) and saturated (饱和的) 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.”
小题1:What's the best title of the text?

A．Junk Food and Depression	B．Depression Prevention
C．Types of Fats and Depression	D．Depression Research

小题2:Which of the following increases the risk of suffering depression?

A．Fish.

Researchers have found more evidence that suggests a relationship between races (种族) and rates (率) of lung cancer among smokers. A new study shows that black people and Native Hawaiians are more likely to develop lung cancer from smoking. It compared their risk to whites, Japanese-Americans and Latinos.
Researchers at the University of Southern California and the University of Hawaii did the new study. The New England Journal of Medicine published the findings. The eight-year research studied more than 180,000 people. They included present and former smokers and people who never smoked. Almost 2.000 people in the study developed lung cancer.
Researchers say genetics (遗传学) might help explain the racial and ethnic（种族的） differences. There could be differences in how people's bodies react to smoke. But environmental influences, including the way people smoke, could also make a difference.
African-Americans and Latinos in the study are reported smoking the fewest cigarettes per day. Whites are the heaviest smokers. But the scientists point out that blacks have been reported to breathe cigarette smoke more deeply than white smokers. This could fill their lungs with more of the chemicals in tobacco that cause cancer.
Scientists know that some diseases effect different groups differently. And some drug companies have begun to develop racially targeted (针对) medicines. Last June, the United States Food and Drug Administration approved a drug designed to treat heart failure in black patients. The name is BiDil. The agency called it "a step toward the promise of personalized medicine."
小题1:Researchers agree that it is that may probably determine black people’s risk of lung cancer.

A．the larger amount of smoking than white people

B．the living style or habit of the blacks

C．the depth of cigarette smoke into their lungs

D．the physical strength to react to cigarette smoke

小题2:People in the new study are made up of .

A．heavy smokers in America	B．smokers and non-smokers
C．the Asians and Hawaiians	D．the black and white people

小题3:The production of BiDil referred to in the last paragraph is to .

A．explain different races react to some diseases differently

B．tell the readers that racial differences exist in smokers

C．show a big step people have taken in the medicine area

D．support the idea that it is easy for blacks to have cancers

小题4:Which of the following statements is TRUE according to the author?

A．The way of smoking may increase the risk of lung cancer.

B．Race has nothing to do with the risk of having a lung cancer.

C．The research was started by the New England Journal of Medicine.

D．he risk of lung cancer lies I how much a person smokes.
