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”.

    The young dolphin swam in the waters off Brisbane, Australia, and found his seafood dinner. Suddenly he realized that he was not the only hungry predator(捕食者)in the area. A ten-foot tiger shark aimed at the same fish. The dolphin refused to give up the meal and dashed to the shark. The shark attacked him, biting down hard into his back. {#blank#}1{#/blank#}

    Later, on the sandy beach nearby, staff at the Tangalooma Resort were shocked to see the severely wounded male. He was a regular visitor, a playful 12-year-old dolphin called Nari. “We've known him all his life, since he was a baby,” says resort director Trevor Hassard. {#blank#}2{#/blank#}The wound measure about a foot long and more than an inch deep. He took photos of Nari and sent them to vets at Sea World, a local marine mammal park. They agreed that Nari needed emergency care.

    The next day, Sea World staff traveled to the beach to catch Nari.{#blank#}3{#/blank#}Nor did he appear the next evening. Everyone was depressed and worried about him.

    {#blank#}4{#/blank#}“I had started thinking the worst,” Hassard says. “Words can't describe how excited we were.” Six rescuers surrounded Nari and carried him to Sea World. The vets performed an operation to remove the dead flesh from around the bite. Nari was then moved to a special pool where his wound was cleaned and treated regularly.

    {#blank#}5{#/blank#}Sea World decided to tansort Nair back to his home beach. Hassard had worried that the other dolphins might reject Nari after such a long absence. That concern disappeared when Nari's friend Echo instantly recognized him and moved close to his side.

A. But Nari didn't show up

B. Three days later, Nari finally turned up.

C. He felt quite worried when he took a close look at Nari's injury

D. After seven weeks, Nari was fully recovered but growing restless.

E. Shark researchers are trying to warn people to escape without being eaten

F. The five-meter-long dolphin simply swam away, disappearing into the water below.

G. Luckily, the wounded dolphin managed to escape from the shark's biting with violent struggle.

How to Make Friends

    Friendship is a very important human relationship and everyone needs good friends. Good friendship has many benefits. It offers companionship, improves self-worth and promotes (促进) good health. There are times in our lives such as when we have recently moved into a new town, or changed our jobs or schools. Such changes often leave us without a friend. {#blank#}1{#/blank#} But for many of us the process is difficult and requires courage. Below are some helpful suggestions on how to make and keep friends.

● Associate with (与……交往) others.

    The first step to making friends is associating with other people. You can go to public places to meet new people. Besides, you will need to make yourself known by becoming an active member of such places.

● Start a conversation.

    Starting a conversation is the second most important step in making new friends. {#blank#}2{#/blank#} You can always start the conversation. Being able to make small talk is a very useful skill in relating with other people.

●{#blank#}3{#/blank#}

    Choosing friends with common interests is important in building friendship as these interests would always bring you and your friend together. Hanging out (闲逛) will always be a pleasant experience.

● Let it grow.

    It is a good thing to stay in touch. However, try not to press your new friend with calls, messages or visits as this would likely wear him or her out and finally you may lose your friend.{#blank#}4{#/blank#} The best friendships are the ones that grow naturally.

● Enjoy your friendship.

    The best way to enjoy your friendship is to allow your friends to be themselves. {#blank#}5{#/blank#} Try not to change them from who they are to what you want them to be. Become the kind of friend you will want your friend to be to you.

A. Do things together.

B. Be cheerful.

C. Making new friends comes easy for some people.

D. So you will need to give your friend time to respond to you.

    I just realized that while children are dogs-loyal and affectionate-teenagers are cats.

    {#blank#}1{#/blank#} You feed it, train it, and boss it around. It puts its head on your knee and gazes at you as if you were a Rembrandt painting. It bounds indoors with enthusiasm when you call it. However, around age 13, your adoring little puppy(child) turns into a big old cat(teenager). Then when you tell it to come inside, it looks amazed, as if wondering who died. Instead of following your doorsteps, it disappears.{#blank#}2{#/blank#}

    Not realizing that the dog is now a cat, you think something must be desperately wrong within. Since you're the one who raised it, you assume that you did something wrong. Now you're dealing with a cat. Filled with guilt and fear, you redouble your efforts to make your pet behave. {#blank#}3{#/blank#} Call it, and it runs way. Tell it to sit, and it jumps on the counter.

    Instead of continuing to act like a dog owner, you can learn to behave like a cat owner. Put a dish of food near the door, and let it come to you.{#blank#}4{#/blank#}You sit still, and it will come, seeking that warm, comforting lap it has not entirely forgotten. Be there to open the door for it. One day your grown-up child will walk into the kitchen, give you a big kiss and say, "You've been working hard all day. Let me get those dishes for you."{#blank#}5{#/blank#}

A. It's so easy to be a dog owner.

B. Children as cats can turn to their parents.

C. You won't see it again until it gets hungry.

D. Then you'll realize your cat is a dog again.

E. Teenagers can understand and appreciate their parents' love.

F. But remember that a cat needs your help and your affection, too.

G. However, all the efforts made before now produce the opposite of the desired result.

    Rather Public speaking and critical thinking

    What is critical thinking? To a certain degree, it's a matter of logic (逻辑) — of being able to spot weaknesses in other people's arguments and to avoid them in your own, it also includes related skills such as distinguishing fact from opinion and assessing the soundness of evidence .

    In the broad sense, critical thinking is focused, organized thinking – the ability to see clearly the relationships among ideas{#blank#}1{#/blank#}The greatest thinkers, scientists, and inventors have often taken information that was really available and put it together differently to produce new ideas. That, too, is critical thinking.

    {#blank#}2{#/blank#} As the class goes on, for example, you will probably spend a good deal of time organizing your speeches. While this may seem like a purely mechanical (机械的) exercise, it is closely connected with critical thinking. If the structure of your speech is loose and confused, chances are that your thinking is also disordered and confused. If, on the other hand, the structure is clear, there is a good chance your thinking is too. Organizing a speech is not a matter of arranging the ideas your already have{#blank#}3{#/blank#}

    What is true of organization is true of many aspects of public speaking.{#blank#}4{#/blank#} As you work on expressing your ideas in clear accurate language, you will improve your ability to think clearly and accurately{#blank#}5{#/blank#} As you learn to listen critically to speeches in class, you will be better able to assess the ideas of speakers in a variety of situations.

    If you take full advantage of your speech class, you will be able to develop your skills as critical thinker in many circumstances. This is one reason public speaking has been regarded as a vital part of education since the days of ancient Greece.

A. Rather, it is an important part of shaping the ideas themselves.

B. This may seem like a lot of time, but the rewards are well worth it.

C. It may also help you to know that there is no such thing as a perfect speech.

D. As you study the role of evidence and reasoning in speechmaking, you will see how they can be used in other forms of communication as well.

E. The skills you learn in your speech class can help you become a more effective thinker in a number of ways.

F. If you are wondering what this has to do with your public speaking class, the answer is quite a lot.

G. It has often been said that there are few new ideas in the world, only reorganized ideas.

    Recently, I've been following a simple rule that is helping me crush procrastination(拖延症) and making it easier for me to stick to good habits at the same time. {#blank#}1{#/blank#} There are two parts to the 2-Minute Rule.

    Part 1—If it takes less than two minutes, then do it now.

    {#blank#}2{#/blank#} For example, washing your dishes immediately after your meal, tossing the laundry in the washing machine, taking out the garbage, sending that email, and so on.

    If a task takes less than two minutes to complete, then follow the rule and do it right now.

    Part 2—When you start a new habit, it should take less than two minutes to do.

    Can all of your goals be accomplished in less than two minutes? Obviously not. But, every goal can be started in 2 minutes or less. {#blank#}3{#/blank#}

    It might sound like this strategy is too basic for grand life goals, but I beg to differ. The 2-Minute Rule works for big goals as well as small goals because of the inertia(惯性)of life. {#blank#}4{#/blank#} I love the 2-Minute Rule because it embraces the idea that all sorts of good things happen once you get started.

    The most important part of any new habit is getting started—not just the first time, but each time. It's not about performance, it's about consistently taking action.

    I can't guarantee whether or not the 2-Minute Rule will work for you. {#blank#}5{#/blank#} Anyone can spare the next 120 seconds. Use this time to get one thing done. Go.

A. I call this little strategy the "2-Minute Rule".

B. And that's the purpose behind this little rule.

C. Here's what you need to know to stop procrastinating.

D. Once you start doing something, it's easier to continue doing it.

E. But, I can guarantee that it will never work if you never try it.

F. The goal is to make it easier for you to get started on the things you should be doing.

G. It's surprising how many things we put off that we could get done in two minutes or less.
