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 life style and this had led to new kinds of sicknesses． {#blank#}2{#/blank#} So they are called "diseases of civilization"．Many cancersand 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 maindifferences between life in ancient times and that of today.

      Stone Age people hunted wild animals for their meat, which hadmuch less fat than domestic ones．They ate a lotof fresh wild vegetables and fruits．They did nothave 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 moresugar．We eat twice as much fat but only one third as much protein andmuch less vitamin C.

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

A．Stone Agepeople lived a simple life.

B．But today, weenjoy 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".

Cowboys in the US

    Cowboys played an important role in the settling of the west. Ranching (牧场经营)was a big industry and cowboys helped to run the ranches.{#blank#}1{#/blank#}

The Roundup

    Each spring and fall the cowboys would work on the “roundup”{#blank#}2{#/blank#} Cattle would walk freely much of the year and then the cowboys would need to bring them in. In order to tell what cattle belonged to their ranch, the cattle would have a special mark burned into them called a “ brand “.

Horse and Saddle (马鞍）

    The most important item of any cowboy was his horse and saddle. The saddles were often custom-made (定制的) and, next to his horse, probably the most valuable item a cowboy owned.{#blank#}3{#/blank#}

Clothing

    Cowboys wore special clothing that helped them with their jobs. They wore large 10-gallon hats to protect them from the sun and the rain. They wore special cowboy boots that helped them to get in and out of the stirrups (马镫）when riding a horse{#blank#}4{#/blank#} Many cowboys wore chaps on the outsides of their legs to help protect them from sharp bushes that their horse may rub up against.

Cowboy Code

    {#blank#}5{#/blank#} The code included such rules as being polite and respectful, always saying “howdy”, not waving at a man on a horse (you should nod) , never riding another man's horse without his permission,always helping someone in need, and never putting on another man's hat.

A. They herded cattle, repaired buildings, and took care of the horses.

B. The cowboys of the Old West had an unwritten code that they lived by.

C. This when the cowboys would bring in all the cattle from the open ranch.

D. Horses were so important that anyone caught stealing a horse was usually hanged!

E. Their clothing grew out of practical need and the environment in which they worked.

F. This was especially important if they fell, so they wouldn't get dragged by their horse.

G. They have deep historic roots dating back to the earliest European settlers of America.

    We all want to do so much: complete our never ending list of tasks and projects, help everyone, travel everywhere, learn a lot of new skills, read every book and watch every good film. {#blank#}1{#/blank#} There isn't enough time in the day, nor do we have much attention to devote to everything.

    Give up on trying to do it all. {#blank#}2{#/blank#} It is important for you to make your days count（有价值）. How do you do that? Here are some ideas:

    {#blank#}3{#/blank#} When you eat a good meal, it's wasted if you actually ignore（不理会）it and are reading on your phone instead. It's an amazing meal only if you really enjoy it. In this way, if we enjoy each moment, they really matter.

    Be satisfied. We always want to do more, be more, experience more. And so, we're never satisfied with the little we actually can do and experience. Instead, we should learn to be happy with what we've chosen to do, knowing that we let go of the rest for a reason. {#blank#}4{#/blank#}

    Realize that we're not really in control. The first few items on this list might give you the idea that you can control your life by simplifying…but the reality is that your day will never go as planned. You can try, but there will always be the unexpected, the unplanned. {#blank#}5{#/blank#} We should learn to appreciate that experience as it comes, whatever it is.

Four Ways to Give Truly Meaningful Gifts

    Buying someone you love a gift that expresses your truest feelings isn't always easy. But when you get it right, the joy they show is worth it. {#blank#}1{#/blank#}

    Listen up.

    While you may think it's a great idea to surprise someone by giving them something you think is meaningful, it's best to get them exactly what they have told you. For example, you heard friends say they wanted the newest bike but you bought them a gym membership instead. {#blank#}2{#/blank#} So get them what they've specially asked for.

    {#blank#}3{#/blank#}

    In the spirit of showing love, we might go big. However, we may not be thinking of what really makes the person happy. You might think buying your father the latest TV is perfect, but then when you get it home, it lights up the living room like a stadium and is totally wrong for the space. So think smart.

    Keep it open.

    Many of us may consider giving cash impersonal （没人情味的）. But this may save you some concern. The receiver can be allowed to choose whatever they want. In a recent survey of over 7,000 Black Friday shoppers, 39 percent said the receiver they were shopping for was “picky （挑剔）”. {#blank#}4{#/blank#}

    Create an experience.

    Visit websites where you can get the latest tickets for a play, buy a surf lesson, or even something unexpected like a flight lesson. {#blank#}5{#/blank#} For example, if your kids are into NASCAR, just imagine the look on their faces when you score them a ride at a race car driving school. So give them a time that they will remember to heart.

A. Ignore the size.

B. Go for something big.

C. Well, that was the wrong move.

D .If possible, cut down the cost of the gifts.

E. These are things that can create a lasting memory.

F. Here's how to discover a gift your receiver will love.

G. So save yourself the second guess and give cash instead.

How to Save Water

    {#blank#}1{#/blank#}, but only 1% is easily accessible to you. Water conservation can be simple, and it starts at home. Whether you're taking showers, doing laundry, saving the water in a pool, or choosing your food, there are several strategies that will help you save water.

    Take shorter showers.

    Taking a shower uses roughly one third of the amount of water used in taking a bath. So'skip the bath and take a short shower instead. Take a CD player into the bathroom with you to challenge yourself. {#blank#}2{#/blank#}. Cutting down your shower time by just two minutes can save 10 gallons of water.

    Make sure you're washing a full load of laundry.

    {#blank#}3{#/blank#}. Put a full load of laundry in so that you'll be sure not to waste water. When washing your clothes, use the economy mode — this will save you both water and electricity!

    {#blank#}4{#/blank#}.

    If you have a pool, using a pool cover at night during the warmer months helps to prevent evaporation. In some places, emptying and refilling a pool is under severe restrictions, or even banned, so preserving this precious resource is crucial.

Eat less meat and dairy

    Growing animal feed uses tons of water, not to mention the amount of water used in the rest of the meat and dairy production process. The more meat and dairy you eat, the more animals are needed to keep up with the demand, so try to limit your intake of such foods.

    Defrost frozen food in the refrigerator.

    While it may be faster to soak your frozen food in water, this isn't necessary and wastes water. {#blank#}5{#/blank#}.

A. Water is a necessary resource for life

B. Water covers 70% of the earth

C. Cover your swimming pool

D Empty your swimming pool

E. Try to finish by the time it is over

F. Try to plan ahead and put the food in the fridge overnight

G. Don't just throw some socks and two shirts in the machine

    Food feeds the soul. To the extent that we all eat food, and we all have souls, food is the single great united across cultures. With food, there are more opportunities to connect to memory and family and place.{#blank#}1{#/blank#} Food as identity. French, Mexican, Chinese, and Italian cuisines each involve dozens of distinct regional foods. Every single culture and religion uses food as part of their celebrations.

    {#blank#}2{#/blank#}Every season, every harvest, and every holiday has its own food, and this is true in America as well.

    {#blank#}3{#/blank#}Sometimes food means living on. While the Chinese cooks who exported “Chinese” food around the world ate authentic cooking at home, the dishes they served, thus creating new cuisines entirely, were based on economic necessity.

    Food as pleasure. Things have changed dramatically in the past 20 years when it comes to food in France. Some of the ideas of French food life may be a performance. France is this pastoral nation where people are spending five hours a day going to 12 different markets to get their food.{#blank#}4{#/blank#}

    Food as status. The introduction of global foods and brands has compounded food as a status symbol for some Chinese.{#blank#}5{#/blank#}In China, people eat food not necessarily for taste, but for texture. You can find food from all of the provinces of China in Shanghai, as well as every kind of global food style imaginable.

A. Food as survival.

B. Food as community.

C. It's the hardest to give up.

D. The celebratory nature of food is universal.

E. It is an accumulation, a function of your experiences

F. How and why you eat your food, is, of course, also very cultural.

G. But food in Italy is love, then nutrition, then history, then pleasure.
