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．Stone Age people lived a simple life.

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

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

D．Ancient people also got lots of physical exercise.

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

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

G．Modern people used to suffer from “diseases of civilization”.

Do you dream?

    Have you ever visited some strange places in your dreams? In fact people have wondered about these strange places for long.{#blank#}1{#/blank#} However, they have been valued as necessary to a person's health and happiness.

    Historically, people thought dreams contained messages from God. It was only in the twentieth century that people started to study dreams scientifically, believing that they tell about a person's character.{#blank#}2{#/blank#} He believed that dreams allow a person to express fantasies or fears, which would be socially unacceptable in real life.

    The second theory to become popular was Carl Jung's compensation theory. Jung, a former student of Freud, said that the purpose of a dream is not to hide something, but rather to communicate it to the dreamer.{#blank#}3{#/blank#} Thus, people who think too highly of themselves may dream about falling; those who think too little of themselves dream of being heroes.

    Using more recent research, William Domhoff from the University of California found that dreaming is a mental skill that needs time to develop in humans.{#blank#}4{#/blank#} Until they reach the age of five, they can not express very well what their dreams are about. Once people become adults, there is little or no change in their dreams. The dreams of men and women differ. For instance, the characters that appear in the dreams of men are often other men, and often involve physical aggression.

    The meaning of dreams continues to be difficult to understand. {#blank#}5{#/blank#} If you dream that a loved one is going to die, do not panic. The dream may have meaning, but it does not mean that your loved one is going to die.

A. Dreams make up for what is lacking in waking life.

B. But anyway, people should not take their dreams as reality.

C. It gives scientists chances to better understand human mind.

D. They have been considered as meaningless nighttime journeys.

E. First, there was Sigmund Freud's theory.

F. They think their mind is trying to tell them something.

G. Children do not dream as much as adults.

    Eyesight（视力) plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight：

    Schedule（安排）yearly exams(检查). {#blank#}1{#/blank#} Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Protect against UV rays (紫外线). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. {#blank#}2{#/blank#}

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products. {#blank#}3{#/blank#} Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

    {#blank#}4{#/blank#} As part of a healthy diet, eat more fruits and vegetables each day. Vitamins (维生素) C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. {#blank#}5{#/blank#} Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

A．Eat your greens.

B．Eye care should begin early in life.

C．They can properly protect your eyes.

D．Stay in good shape by taking more vitamins.

E．Parents usually don't care about their own eyesight.

F．Always follow the doctor's advice for appropriate（适当的）wear.

G．This frequent eye activity increases the risk for eye tiredness.

    Commercial advertisement was once thought of as a technique of the marketers to inform the potential buyers about the availability of certain products. It was seen more as a medium to inform the buyers rather than persuade them to buy. The present day marketers see advertisement as a medium to damage the image of their competitors and their products. This indeed, is an undesirable and an immoral practice. Instead of speaking about their own products, these marketers speak about the drawbacks (often without any basics) of the competing products.

    People watching TV advertisements would notice that there has always been an advertisement war between the marketers of different consumer goods. A few such cases are given below.

⑴Parachute Coconut Oil vs. V.V.D. Gold

Sometime back, the producer of V.V.D Gold Coconut Oil claimed in their TV advertisement that only their products were superior and the one sold in blue colour bottles (the reference was to Parachute coconut oil) was suitable only for un-natural hair.

⑵Tata Salt vs. Captain Cook

Tata salt was first iodised (碘处理) salt marketed by an Indian Company. It has been enjoying a good and steady market. Captain Cook, another producer of iodised salt, who entered the market later, had to adopt some strategy to get control of the market. The TV advertisement of Captain Cook stressed on ‘Free flow' of their salt when transferred to a container. The producer of Tata Salt retaliated (报复) by saying that the claim of Captain Cook was a trick and those who were quality conscious should deal with it with caution.

⑶Pepsi vs. Coca Cola

Coca Cola was selected as the official soft drink for the Wills World Cricket 1996. When the cricket series was on, the marketers of Pepsi constantly advertised on TV. Their advertisement gave the idea that the cricketers preferred only Pepsi and as a matter of fact there was nothing official about it.

⑷Horlicks vs. Complan

Sometime back, the TV advertisement of Complan, a health drink directly attacked Horlicks, which has been in the market for several decades. The claim of Complan was that their brand (which according to them was Brand C) has a higher percentage of ingredients compared to Brand H (reference was nothing but to Horlicks).

The above examples clearly show how the technique of advertisement is misused by some marketers to ruin the image of their competitors. This, certainly, is not a healthy trend.

    Any marketer should only speak about his products and not about his competitors' products. The awareness of consumers has certainly increased over the years and they are no longer easily taken in. There are many consumer products like salt, oil, shaving blades etc. But one thing for sure is that offering the same product in a different container will not make the product different.

    Mass media like Radio, Television and newspaper should not allow advertisements that tell lies. Legal regulations, in this regard, should also be made stricter.

    When you think about people who have made the world a better place, you probably think of famous scientists or great leaders. That is not all the truth.  {#blank#}1{#/blank#} An act of kindness can bring a smile to a person's face even if only for a moment.

    Give away your money.  {#blank#}2{#/blank#} For example, if you want to help hungry children, you can try to find an international organization that provides food for those in poor areas. Every cent you give away will mean a lot.

    Help a stranger. Your small actions can brighten the day of others. Hold the door for someone whose hands are full. Help the blind cross the street.  {#blank#}3{#/blank#} The key is expecting nothing in return for your acts of kindness.

    Care about those you know. Show the people close to you how much you care about them. Tell them they mean a lot to you. Make a beautiful gift for a friend. Take your husband to his favorite fun place if he has had a hard week.  {#blank#}4{#/blank#}

    Be grateful to others. Have you had good service in a restaurant？Thank the waiter. Do you have a very good neighbour who is always there when you need her？Tell her how much you appreciate her being in your life.

    {#blank#}5{#/blank#} If a friend needs skills in a certain area, offer your advice. Perhaps she is struggling to set up a computer, and you know how to do that. Offer whatever ability you have, but always remember to be polite.

A. Keep walking forward.

B. Share your knowledge.

C. Small steps, not big ones.

D. Give your seat on the bus to an old man.

E. Choose a charity that has meaning for you.

F. Tell your children how much they mean to you.

G. Ordinary people like you and me can also help a lot.
