Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago．{#blank#}1{#/blank#}

    The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses．{#blank#}2{#/blank#} So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.

    Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none．{#blank#}3{#/blank#} However, a change in food is one of the main differences between life in ancient times and that of today.

    Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains．{#blank#}4{#/blank#} We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.

    {#blank#}5{#/blank#} But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

 A．Modern people used to suffer from "diseases of civilization".

 B．People today probably don't want to live like our ancestors.

 C．These new sicknesses were not known in ancient times.

 D．Ancient people also got lots of physical exercise.

 E．In that case, they would live much healthier.

 F．But today, we enjoy eating a lot of these.

 G．Stone Age people lived a simple life.

    Most of us lead unhealthy lives; we spend far too much sitting down. If in addition we are careless about our diets, our bodies soon become loose and fatty and our systems slow moving.

    {#blank#}1{#/blank#}. I am thinking of such features of modern city life as pollution, noise, rushed meals and stress. But keeping fit is a way to reduce the effects of these evils. The usual suggestion to a person who is looking for a way to keep fit is to take up some sport or other. While it is true that every weekend you will find people playing football and hockey in the local park, they are outnumbered a hundred to one by the people who are simply watching them.

    For those who do not particularly enjoy competitive sports—{#blank#}2{#/blank#}—there are such separate activities as cycling, walking, jogging and swimming. What often happens though is that you do them in such a leisurely way, so slowly, that it is doubtful if you are doing yourself much good, except for the fact that you have at least managed to get up out of your armchair.

    Even after you have found a way for keeping in shape, through sport or gymnastics, {#blank#}3{#/blank#}, because, according to the experts, you must also master the art of complete mental and physical relaxation(放松). {#blank#}4{#/blank#}. Yoga, as practiced in the West, is the most widely known and popular of the systems for achieving the necessary state of relaxation. It seems ironical (讽刺性的), though, that as our lives have improved in a material sense we have found it increasingly necessary to go back to forms of activity—{#blank#}5{#/blank#}—which were the natural way of life of our forefathers.

A. be active and practise Yoga

B. There are some aspects of our unhealthy lives that we cannot avoid

C. and it is especially difficult to do so if you are not good at them

D. physical effort on the one hand and relaxation on the other

E. they spent most of the time out of doors

F. you are still only half way to good health

G. It has to do with deep breathing, emptying your mind of all thoughts, meditation, and so on

Most Valuable Possessions on Earth

Marie was a single mother of two children in a rural Missouri community. {#blank#}1{#/blank#} She also dedicated much spare time to numerous charities and community projects.

    Then one day Marie received some shocking news from her doctor. She had cancer, and it was spreading rapidly. {#blank#}2{#/blank#}

    Soon, Marie witnessed what she had always known: although she was not financially wealthy, she already had the most valuable possessions on earth. Hundreds in her community and surrounding areas teamed up to help her and her family.

    Many people she had touched in caring ways demonstrated appreciation for Marie's life. {#blank#}3{#/blank#} However, she lived long enough to feel the love of those she had cheerfully served.

    The spirits of love and gratitude multiply(增加) when they are shared. {#blank#}4{#/blank#} Giving selflessly was a value that Marie displayed all her life, and her spirit of giving lived after her in those who knew and loved her.

    All her life, Marie had demonstrated（演示） the truth of this simple principle : {#blank#}5{#/blank#} Rather, it is an attitude that comes from appreciating what we already have. We can find the happiness we seek if we will first share it with others. Then —— and only then——we will have the most valuable possessions on earth: love, happiness, and increasing gratitude.

A. Happiness is the result of sharing love and gratitude.

B. She worked full-time during the day and sold handcrafted leather gifts on weekends.

C. She lived a rather poor and hard life with the two children.

D. Marie didn't live to see the day when her bills were fully paid.

E. Love is second to none.

F. She had barely enough resources to put a cent in the medical treatments she would need.

G. Happiness will not come from worldly possessions of fortune.

    Does Using Technology in the Classroom Help College Students?

    Almost anywhere in the world, you are likely to find people doing the same thing in public places, on trains and buses or wherever else you look. They spend their day looking at laptop computers, smartphones or other personal electronic devices. They are thinking mainly about their electronic devices, and not much else.

    {#blank#}1{#/blank#} More and more college students have no problem walking into a classroom and immediately opening their laptops. Others may spend an entire study period with a smartphone in hand. {#blank#}2{#/blank#} But recent research suggests that using technology during class time may harm college students' ability to remember and process the subject material they are learning.

    Arnold Glass, a professor in Rutgers University in New Brunswick, New Jersey, and a student researcher investigated the issue of divided student attention. During half of their daily class periods, the students in their study were permitted to use any electronic device as much as they wanted. {#blank#}3{#/blank#}

    The students' academic performance was measured in several ways throughout the semester. They took a short test every day, longer tests every few weeks and a final exam covering all the class material. The researchers found that the average daily quiz results showed no evidence of harmful effects from the use of technology. {#blank#}4{#/blank#} They showed that all the students performed poorly on questions covering material taught on days when they were permitted to use technology in the classroom.

    Glass says that it shows the use of electronic devices in the classroom prevents students from processing information. The students hear what the professor is saying. But they might be buying things online or reading unrelated emails at the same time, for example. So they are not thinking deeply about the subject matter as they are hearing it. {#blank#}5{#/blank#}

A. The same can be said about the world of college education.

B. However, the average results of the larger tests and final exam told a different story.

C. And that, Glass says, makes it harder for the information to enter their long-term memory.

D. Technology, in general, is not the only way that students find to distract themselves in class.

E. But even if technology is helpful to some students, there are times when it needs to be turned off.

F. Some students argue that the increasing use of technology can have many helpful effects on society.

G. During the other half, researchers closely watched them to make sure no one was using any technology.

    Music education is the learning of all aspects of music as a separate field altogether. {#blank#}1{#/blank#} The main components of music education is everything from the history of music, musicians who have reached a respectable level, basic notes of music, different types of music, and many other things about music.

    Music education is very important in schools. {#blank#}2{#/blank#} As the child starts learning music from an early age, he would turn out to be a skilled musician. And then he can use his talent for many purposes, such as being a music teacher and teaching other students, or using his musical talent to earn his living.

    According to a survey conducted by elementary schools and high schools, students who were taught music and had a good interest in it academically performed far better than those who were not into music learning. {#blank#}3{#/blank#} While learning music, students learned to count, to multiply and to divide. At the same time, science helped them discover what sounded good together and what didn't. It is also a proven fact that students who have the knowledge of and interest in music tend to plan and organize actions efficiently in their personal lives. {#blank#}4{#/blank#} They do not get aggressive very soon. Furthermore, children learning music are found to be fun-loving and are great at communicating with others.
