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”.

Four simple ways to stay positive

    Trying to stay positive, both in good times and bad, is a great way to improve your quality of life. Try these four methods on a daily basis.

1）. Don't think a lot about negativity.

    Of course. Staying positive 24 hours a day, seven days a week is a bit difficult. Letting things get to you is normal, and it's actually healthy to cry or express frustrations once in a while.

    It's when those negative moments control your life that your emotional balance is at risk. {#blank#}1{#/blank#} However, don't give that sadness another second in your day.

2）. {#blank#}2{#/blank#}

    What you put into your body directly affects how you feel on the outside. Fill yourself with good, healthy foods like fruits and vegetables and limit snacking. Exercise is equally of great importance. Take a few days out of your week for at least half an hour of activity, and try to stick to it. {#blank#}3{#/blank#}

3）. Be kind to others.

    {#blank#}4{#/blank#} Making someone's day a bit brighter not only puts a smile on his or her face, but also yours as well. Remember to smile and treat each person with pity and respect. Good deeds are contagious（传染的）, and your positive attitude may spread among others.

4）. Take it one day at a time.

    Being positive isn't an instant thing. It's a steady effort that we follow every hour of every day. {#blank#}5{#/blank#} Instead, focus on living at the moment and doing what you can to make each moment better.

A.Eat healthy and stay fit.

B.Take your lunch breaks outside.

C.Don't worry about what the future may bring.

D.Gratefulness helps you appreciate life in bad times.

E.Good feelings come from acts of kindness and selflessness.

F.Take a few minutes to feel sad and accept what happened.

G.Even going outside for a walk and enjoying the sunshine improves your mood.

    Breaking bad eating habits and starting good ones is one of the healthiest steps you can take.

    But making healthy choices natural can take time.{#blank#}1{#/blank#} In fact, it can take a certain time for a new habit to feel natural. So how do you stay on track until your new healthy-eating plan takes hold?

    {#blank#}2{#/blank#}Setting too many goals or too many unrealistic ones can disturb you right from the start.

    Think about why you're snacking.{#blank#}3{#/blank#}Or are you just bored or maybe a little stressed out? Skip the extra calories and take a five-minute walk instead.  {#blank#}4{#/blank#}The buddy(好友)system will keep you both on track. If you fail, don't give up. According to the European Journal of Psychology study, little bumps(凸块)in the road aren't likely to disturb the process of creating new habits. So, be patient and get back to your healthy ways as soon as you can.{#blank#}5{#/blank#}

A. Start small.

B. Are you really hungry?

C. Try to do something big

D. With a little patience, those bad habits will soon be gone

E. After all, it's hard to change a lifetime of bad habits overnight.

F. What kind of food do you want to eat when you are hungry?

G. And find a friend or co-worker who wants to make healthy changes, too.

    Penguins are flightless birds that spend half their time on land and half in the water.

    {#blank#}1{#/blank#} They have dark and white feathers, and their wings have evolved into flippers(脚蹼).Most penguins feed on fish, squid and other forms of sea life caught while swimming.

    {#blank#}2{#/blank#} They are mostly found in groups that include thousands of penguins. Penguins each have their own unique mating call, and they use that to locate their mate and chicks in such a large group.

    Although almost all penguin species are native to the Southern Hemisphere, they are not found only in cold Antarctica.{#blank#}3{#/blank#} Several species are even found in the temperate zone, and one species, the Galátpagos penguin, lives near the equator(赤道).

    Unfortunately, many penguin species worldwide are facing threats. The biggest is climate change and global warming. As the earth warms up, the sheets of ice have melted, and the algae(藻类)that grow under the ice decrease. The algae are eaten by tiny creatures called zooplankton. When there is a drop in zooplankton, it affects the fish that depend on it.{#blank#}4{#/blank#}

    Another major threat is from oil spills. If coated with oil, penguins cannot float or swim in water. Also, if oil is swallowed, penguins will die from poison.{#blank#}5{#/blank#}

A. These birds are very social.

B. In fact, only a few of them live so far south.

C. Penguins are highly adapted for life in the water.

D. The biggest threat for penguins comes from humans.

E. They have a tendency to live in a community together.

F. As a result, penguins have less fish to eat and thus starve.

G. Others include overfishing, illegal egg harvesting, and natural enemies.

    All over the world people are hooked on sports, which help them to strengthen their body and build their character.{#blank#}1{#/blank#}They improve the participants' physical skills, and provide entertainment for the audience as well.

    Many people like to watch others play games.{#blank#}2{#/blank#}Often they get very excited when “their” player or team wins. If they are crazy about the game or the player, then they'll become their die-hard fans. Some sports are so interesting that people everywhere go in for them. Football, for example, has spread around the world. Swimming is popular in countries near the sea or in those with many rivers.{#blank#}3{#/blank#}And think of people in cold countries. Masses of people love to skate or ski in Japan, Norway or Canada.

    {#blank#}4{#/blank#}Chinese boxing, also has a very long history. But basketball and volleyball are rather new, which started in the late of the nineteenth century. People are inventing new sports or games all the time. Water skiing, as a modern game, is one of the newest in the family of sports.

    People from different countries or races may not be able to understand each other, but after a game, they get to know each other better and they often become good friends.{#blank#}5{#/blank#}They learn to fight hard but fight fair, to win without pride and to lose with grace. They also learn to be competitive and optimistic, which will equip them for life challenges in the future.

A. They buy tickets or turn on the TV to watch the games.

B. What fun it is to jump into a pool or lake, whether in China, Egypt or Italy!

C. Some sports or games date back thousands of years, like running or jumping.

D. Sports help to train a person's character.

E. Chinese people liked doing sports even in ancient times.

F. Sports are competitive physical activities or games through casual or organized participation.

Best Way to Lose Weight – Dieting Tips

    How do you eat right to lose weight fast? You'll discover there are a great number of weight loss diets which promise to help you drop the pounds fast.{#blank#}1{#/blank#}

    Many weight loss diets are aimed at losing weight fast, but aren't necessarily healthy and won't create a long-term change for the better. {#blank#}2{#/blank#} That means you'll choose a diet which doesn't cut out any necessary nutrients(营养物). Most diets suggest that you stop eating fat or carbs(含碳水化合物的食物).{#blank#}3{#/blank#} You'll need to make clear of your own body type before making a diet plan. You might also need to try different ways before finding the best way.

    If you just need to shake a few pounds off, your plan won't be the same as one to lose weight in the long term. The best short-term weight loss plan will be stronger than the best long-term weight loss plan, but it shouldn't get rid of necessary nutrition. {#blank#}4{#/blank#}Your body will go into "starvation mode" and your metabolism(新陈代谢) will slow down. As a result your body will keep more weight.

    {#blank#}5{#/blank#} Spread out your meals evenly throughout the day. Any larger meals should be eaten earlier in the day. That gives your body more time and opportunity to burn calories. If you eat a lot before bed, those calories won't burn but become fat.

A. In fact many people feel it hard to lose weight.

B. Once you start your plan, you shouldn't stop.

C. But do they really work?

D. If you try to make yourself feel hungry, you won't achieve long-term results.

E. The best way to lose weight should be useful in the long term.

F. While this may help some people, there is no plan that is perfect for all.

G. Besides improving your metabolism, you also should pay attention to when you eat.
