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".

    Safety in the highway is not totally out of our hands. Here are four ways we can protect ourselves when we travel.

    {#blank#}2{#/blank#} people in small cars are injured more often and more severely than people traveling in large cars. Factories of small cars are strengthening their products' safety, which helps. But the mix of large cars and small cars on the road is the main reason of the problem.

    Being thrown into glass and mental cars parts, or being thrown from the car can really hurt or even kill you.

    {#blank#}3{#/blank#}The safety belt's main purpose is to pull you back if your car has a sudden crash with another vehicle or object, or if it rolls over. A belt can reduce the chance of deadly injury by 45% and the chance of serious injury by 50%.

    Air bags are important. More than half of all new cars sold have air bags. Air bags provide protection in frontal crashes—the type of crash that kills the most drivers—when they are also wearing safety belts. Most people are demanding air bags in the cars they buy.  {#blank#}4{#/blank#} Effective as they are, they can't take the place of safety belts.

    Drunk driving crashes are less likely to happen if you don't drink. {#blank#}5{#/blank#}Many people have realised that drunk driving can lead to death and injury, prison time and other results. There are movements to strengthen penalties(处罚) for drinking and driving.

A. How to drive safely?

B. You are safer in a large car

C. How to protect ourselves in the highway?

D. Air bags are not installed in all cars.

E. That's why safety belts should be worn.

F. Drunk driving is the most serious problem.

G. But the protection provided by air bags is limited in side or rear crashes.

    A major source of teen stress is school exams, and test anxiety is not uncommon. When you recognize your teen is under stress, how can parents help your teen stay calm before an exam?

    Be involved. Parents need to be involved in their teen's work. {#blank#}1{#/blank#}What they look for is your presence - to talk, to cry, or simply to sit with them quietly. Communicate openly with your teen. Encourage your teen to express his worries and fears, but don't let them focus on those fears.

    Help them get organized. {#blank#}2{#/blank#}Together, you and your teen can work out a time-table in which she can study for what she knows will be on the test.

    Provide a calm setting. Help your teen set up a quiet place to study and protect his privacy. Give them a nutritious diet. It's important for your teen to eat a healthy, balanced diet during exam times to focus and do her best. {#blank#}3{#/blank#}If this happens, encourage your teen to eat light meals or sandwiches. A healthy diet, rather than junk food, is best for reducing stress.

    {#blank#}4{#/blank#}Persuade your teenager to get some sleep and/or do something active when she needs a real break from studying. Making time for relaxation, fun, and exercise are all important in reducing stress. Help your teen balance her time so that she will feel comfortable taking time out from studying to spend time with friends or rest.

    Show a positive attitude. {#blank#}5{#/blank#}Your panic, anxiety and blame contribute to your teen's pressure. Make your teen feel accepted and valued for her efforts. Most importantly, reassure your teen that things will be all right, no matter what the results are.

A. A parent's attitude will dictate their teen's emotions.

B. Exam stress can make some teens lose their appetite.

C. They will only make the situation worse.

D. Encourage your teen to relax.

    Memory is our ability to learn something, save it and recall it when needed. Our memories are important to our sense of self, our personalities, and our ability to understand the world.

    {#blank#}2{#/blank#} There is short-term memory and long-term memory. Your short-term memory saves information for a few seconds or a few minutes. {#blank#}3{#/blank#} Long-term memory involves the information you try hard to keep, because it's meaningful to you-an example is data about family and friends. And then there is visual memory and sound memory. But these are not hard and fast. In fact, Scientists argue a lot about the nature of memory.

    {#blank#}4{#/blank#} Some memorize better with the help of pictures. Others are helped more by sounds. One thing's for sure though: If you can put the different kinds of memory together, there can be great results. {#blank#}5{#/blank#} At the same time, you could listen to recordings of the same group of words. These things may help when it comes to memorizing the words.

    Imagination and association can be useful too. By imagination, scientists mean picturing a word in your mind, while association means relating the word to something you already know.

A. So why not try pictures with English words?

B. Then how do chimps have better memories than us?

C. Scientists say that there are different types of memory.

D. We may have to rethink what we believe about human memory.

E. Scientists have also found that people memorize things in different ways.

F. For example, the time it takes to compare the prices of a few items in a store.

G. Short-term and long-term memory differ in the amount of information they can store.

    Every one complains. Even if you argue that you are the happiest person in the world you still complain sometimes. Sometimes you complain without even realizing it, but rarely is it ever helpful. {#blank#}1{#/blank#}Here are some tips to stop complaining and give up the negative thoughts:

    Lots of people give you advice on overcoming (克服) fear. {#blank#}1{#/blank#}  However, I want to tell you that a world without fear would be more dangerous, less rewarding. So we want to treat fear as a friend？Here are three reasons. 

    {#blank#}2{#/blank#} Think about it. Do you get more nervous when you meet the girl (or guy) of your dreams？Which is more fearful, talking to the boss of your company or to some of your friends?{#blank#}3{#/blank#} If you didn't have fear to guide you, you might not know that! Not so bad, right？

    Next, fear encourages us to take action. Fear is a call to action. In the past, our ancestors (祖先) didn't run away in fear when they saw a tiger running toward them but tried to kill it for food. Now, most of us don't face serious danger like hungry tigers every day, but we do face serious bosses or public speaking. So, what can we do？{#blank#}4{#/blank#}

Lastly, fear lets you know you are alive. Why do we like roller coasters (过山车)？{#blank#}5{#/blank#} Same for horror movies.

    So fear can guide you towards what's important for you and encourage you to take action to improve. Don't we all need that kind of friend？

A. Don't fear to be wrong.

B. It frightens us in a mostly safe way.

C. Imagine what life would be like without fear.

D. The first is that fear is an excellent guide to opportunity.
