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．  (1)  

      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．  (2)  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．  (3)  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．  (4)  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.

        (5)  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.

  If you donˈt finish your homework during school，think about how much you have left and what else is going on that day，and then budget your time．Most high-school students have between 1and 3hours of homework a night．If itˈs a heavy homework day and it seems like youˈve got an assignment in every subject but gym and lunch，youˈll need to devote more time to homework．Itˈs a good idea to come up with some kind of homework schedule，especially if you are involved in sports or activities or have an after-school job．

Are you new to experiencing relationships? Well，let me give you some advice on how to have a healthy relationship with your partners.

．Be an honest person with them.

Donˈt hide things from them，and donˈt lie. Donˈt be afraid to say things that arenˈt flattering about yourself. Getting them to trust you is the most important thing in any relationship. If there is no trust，thereˈs nothing there.__(1)__

．Make sure you give them respect.

Now，respect isnˈt just simply treating them nicely.__(2)__ You have to learn to adjust to their liking. Basically，learn to study your partnerˈs moods，wants and needs. Donˈt just think about yourself，but think about what your partners need as well.

．Make sure you are encouraging to your partners.

Always be willing to help them and give them honesty and positive things at the time. __(3)_ Make them feel you are someone they can count on and build a future with.

．Make sure you have a good sense of humor with them.

Laughter is the key to happiness. Laugh a lot with them，and joke with them, __(4)_ Laughter may seem silly，but itˈs the secret to a lot in life. It will keep the sparks alive.

．Make sure the communication is good.

This usually goes along with trust，so always communicate how you feel even if itˈs something that upsets you._(5)_ If they did something that made you unhappy，tell them about it in a respectful manner. Itˈs important to communicate this to them，not to keep it bottled up.

If you find yourself losing the motivation（动力） to do your homework, you are not alone.  (1)  If you want to get good grades, of course, you must do your homework. Here’s how to find the motivation:

  (2)  If you are too tired, you’ll just want to watch television instead of thinking about your homework. Plus, you’ll have a much easier time remembering what you’ve read if you are energetic.

Turn off the distractions（分散注意力的事）.Turn off the music and television. If you don’t need your computer or the Internet for your homework, turn it off as well. Make sure your study area is free from distractions.  (3)  

Start right away. Doing your homework right after you get home can keep you from falling into the trap of endless hours of distractions.  (4)  Although it may not be popular to do your homework on a Friday night, you’ll have the rest of the weekend free.

Create a schedule.  (5)  Plan out when you will do each part of the assignment. Split them into small parts, so that you can feel good about completing each part. It can be much easier to deal with a big assignment or project once you’ve split it into manageable pieces.

Homework can be boring, but it’s a necessary evil if you want to pass your classes. Once you make a plan to finish your homework, stick to it.

How to Stop Worrying About Being Perfect

    We don't have to be perfect all the time. Perfection is an illusion (幻影) because we are all human.  (1)  Even something like a weather report or a stock prediction is out of date the second it's released (发布).

Question your thinking.

      (2)   It's so subjective. It's up to us. It's not what someone else does, has, or delivers. So, ask yourself, “What do I really want?” When you find out—ooh! What a relief！

  (3)  

    Sheryl Sandberg explains that she constantly gets long emails from customers and colleagues that want long responses in return. But busy as she is, she'll often reply in one sentence because it's done that way. So forgive yourself for doing the similar thing when you need to. “Done is better than perfect,” as they say.

Don't jump to judgment.

    There's no one more critical (爱挑剔的) of you than you.  (4)  Because we tend to focus on what's going wrong in our study and live over what's going right. If you have done your best, that is excellent. Go on!

Enjoy the process.

    Life is 99 percent journey. Yes, we have those great moments that unforgettably bring us joy—that praise from our teacher, the lovely touches from our parents, whatever it is—but that lasts…well…a few seconds, really. We get used to it pretty fast.  (5)  

My father used to be an amateur wrestler and national champion. He was forced to give up the sport in order to obtain gainful employment, which meant he wouldn’t be able to win a medal for our country. Therefore, he made a vow that his unborn son would.   (1)  

He was about to give up the hope when one day, my younger sister Babita and I beat up two boys accidentally in response to critical comments. My dad found our potential to become wrestlers and began coaching us.   (2)   We were required to do physical training early in the morning and have a short haircuts to avoid lice.

   (3)   We would complain about him all the time. Gradually, I realized that he wanted us to have a good future and not grow up to be ordinary housewives. Motivated, we willingly participated in his coaching.

With great efforts, he made us competitive wrestlers and I won the junior and senior championships, providing me with a chance to gain training in a National Sports Academy, where pride and agony fulfilled my mind.   (4)  As a result, I found myself losing every match at the international level. After that, I tearfully made peace with papa and turned to him for help. Then he coached me patiently.

Despite difficulty, I finally became the first Indian female wrestler to qualify for the Olympics, inspiring dozens of Indian women to take to wrestling. Even now, papa’s words are still in my mind: “ Geeta, think about all the girls who are thought to be inferior to boys, girls who are forced to do chores, girls who are married and have children. Not only will you compete with other countries, but also with those who look down upon women!” . I will never forget our father’s instruction.   (5)  

People lie all the time，but depending on how skilled they are．It can be difficult to determine when someone is lying to you．Do you know how to recognize the signs that someone is lying to you？ ___(1)___

Everyone knows that fish is good for health.   (1)   But it seems that many people don’t cook fish at home. Americans eat only about fifteen pounds of fish per person per year, but we eat twice as much fish in restaurants as at home. Buying, storing, and cooking fish isn’t difficult.   (2)  This text is about how to buy and cook fish in an easy way.  (3)   Fresh fish should smell sweet: you should feel that you’re standing at the ocean’s edge. Any fishy or strong smell means the fish isn’t fresh.   (4)  When you have bought a fish and arrive home, you’d better store the fish in the refrigerator if you don’t cook it immediately, but fresh fish should be stored in your fridge for only a day or two. Frozen fish isn’t as tasty as the fresh one.

There are many common methods used to cook fish.    (5)    First,clean it and season it with your choice of spices(调料).

Put the whole fish on a plate and steam it in a steam pot for 8 to 10 minutes if it weighs about one pound. (A larger one will take more time.) Then, it’s ready to serve.
