What makes one person more intelligent than another? What makes one person a genius, like the brilliant Albert Einstein, and another person a fool? Are people born intelligent or stupid, or is intelligence the result of where and how you live?{#blank#}1{#/blank#}

    We know, however, that just being born with a good mind is not enough. In some ways, the mind is like a leg or an arm muscle.{#blank#}2{#/blank#} Mental exercise is particularly important for young children. Many child psychologists think that parents should play with their children more often and give them problems to think about. {#blank#}3{#/blank#}38．__ If, on the other hand, children are left alone a great deal with nothing to do, they are more likely to become dull and unintelligent.

    {#blank#}4{#/blank#} According to some psychologists, if parents are always telling a child that he or she is a fool or an idiot, then the child is more likely to keep doing silly and foolish things. So it is probably better for parents to say very positive things to their children, such as “That was a very clever thing you did.” or “{#blank#}5{#/blank#}”.

A. A healthy body contributes to one's intelligence.

B. Parents should also be careful about what they say to young children.

C. What people want to express is like this.

D. The children are then more likely to grow up bright and intelligent.

F. You are such a smart child.

G. These are very old questions and the answers to them are still not clear.

    Eyesight（视力) plays a very important role in our daily life. Every waking moment, the eyes are working to see the world around us. Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight：

    Schedule（安排）yearly exams(检查). {#blank#}1{#/blank#} Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Protect against UV rays (紫外线). Long-term stay in the sun creates risk to your eyes. No matter what the season is, it's extremely important to wear sunglasses. {#blank#}2{#/blank#}

    Give your eyes a break. Two-thirds of Americans spend up to seven hours a day using computers or other digital products. {#blank#}3{#/blank#} Experts recommend that people practice the 20/20/20 rule: every 20 minutes, take a 20-second break and look at something 20 feet away.

    {#blank#}4{#/blank#} As part of a healthy diet, eat more fruits and vegetables each day. Vitamins (维生素) C and E help protect eyesight and promote eye health.

    Practice safe wear and care of contact lenses (隐形眼镜). Many Americans use contact lenses to improve their eyesight. While some follow the medical guidance for wearing contact lenses, many are breaking the rules and putting their eyesight at risk. {#blank#}5{#/blank#} Otherwise, you may have problems such as red eyes, pain in the eyes, or a more serious condition.

    Arguments happen in every healthy relationship—we know it sounds contradictory, but it's true—but they can still have a negative impact if they aren't handled properly. .{#blank#}1{#/blank#}

    Take a breath. We know that it can be hard to think clearly when you are angry, so we would first like to encourage you to try to take a second to collect your thoughts before engaging in a dialogue with your partner{#blank#}2{#/blank#}If you are not careful you could potentially say what might damage your relationship.

    Take the situation as it is. Even though you are angry and it can be hard to be objective, try to see the situation for what it is. Do not escalate (不断恶化) the argument{#blank#}3{#/blank#}Try to understand the purpose behind the action—if something happened accidentally, you should not treat as if it were done intentionally.

    {#blank#}4{#/blank#} If you have done something wrong, the best possible option for you is to admit it. Denying something only makes it more hurtful and often your partner will be able to forgive you much more quickly if you are honest.

    Set ground rules. After a fight you and your partner can have a heart-to-heart talk of what happened{#blank#}5{#/blank#} At this point you can set some ground rules for future fights, like not cursing each other or calling each other's names, which might help reduce the intensity of your fights.

How to Retain More of Every Book You Read

    In recent years, I have focused on building good reading habits and learned how to read more. For most people, the final goal of reading a nonfiction book is to actually improve their life by learning a new skill, understanding an important problem, or looking at the world in a new way{#blank#}1{#/blank#} With that in mind, I'd like to share three reading comprehension skills that I use to make my reading more productive.

    Make all of your notes searchable. Having searchable book notes is important for returning to ideas easily{#blank#}2{#/blank#} An idea is only useful if you can find it when you need it. There is no need to leave the task of reading comprehension merely up to your memory.

    {#blank#}3{#/blank#} When you go to the library, all of the books will be divided into different categories. In the real world, of course, knowledge is not separated into neatly defined boxes{#blank#}4{#/blank#}For that reason, I try to consider how the book Fm reading is connected with all of the ideas that are already inside my head. Whenever possible, I try to combine the lessons Fm learning with previous ideas.

    Summarize the book in one paragraph{#blank#}5{#/blank#}It forces me to review my notes and consider what is really important about the book. In many cases, I find that I can usually get just as much useful information from reading my one-paragraph summary and reviewing my notes as I would if I read the entire book again.

A. Combine thoughts as you read.

B. All knowledge is interconnected.

C. Describe the book to your friends.

D. Read widely if you want to practice the skills.

E. It increases the chances that you will apply what you read in real life.

F. Once I finish a book, I challenge myself to conclude the text in just three sentences.

G. It's important to read books, but it is just as important to remember what you read and use it.

How to Master Your Public Speaking Voice

    Public speaking skills can be a disaster if you don't know how to use your voice. However, a little bit of practice and a confident outlook can help you to be a fantastic public speaker. {#blank#}1{#/blank#}.

    Learn the sound of your own voice

    Record yourself as often as possible—speaking your thoughts aloud, having conversations with friends, giving a presentation at work, etc. so you can hear what your voice sounds like when you are relaxed, having fun, and in stressful situations. {#blank#}2{#/blank#}.

    Master your breathing

    The first step in developing a strong public speaking voice is mastering your breathing. {#blank#}3{#/blank#}, which causes their voices to sound high and weak. Develop a habit of breathing deeply at a controlled pace throughout the day so that when it comes to your time to speak, you'll have less trouble doing it.

    {#blank#}4{#/blank#}.

    It's not just your breathing and vocal cords (声带) that have a physical vocal on your voice. When it comes to public speaking, it is essential that you stand or sit with your back straight. This makes your voice stronger and clearer by allowing you to breathe deeper. It also has the added benefit of making you look more confident.

    Adjust your speaking rate

    Speaking too slow can cause people to get bored while speaking too fast can be hard to follow. {#blank#}5{#/blank#}. The best speaking rate is in the range of 120-160 words per minute. Practice to control your time.

    Imagine that you are in a remote village somewhere with no medical clinic. {#blank#}1{#/blank#}Once the doctors get to you, they examine you and take blood samples, but they won't be able to help you until they take the samples back to the hospital to find out what is wrong. {#blank#}2{#/blank#} Thanks to engineer Andy Ozcan, many people may never be in this situation. He has invented an app that turns your mobile phone into a diagnostic(诊断的)tool.

    Ozcan's invention is important because it is very accurate and easy to use. In many remote places, even if doctors have microscopes and other instruments to help them make diagnoses, there may still be other problems. Many doctors, for example, don't have enough training to correctly interpret what they see. {#blank#}3{#/blank#} With Ozcan's mobile phone app, health workers can take a special photo of a blood sample and send it to a central computer at a hospital. The computer will then automatically interpret the photo and send a diagnosis back in a few minutes.

    {#blank#}4{#/blank#} His technology only requires a mobile phone and an Internet connection. As more than four billion people already have cell phones, the cost of establishing the diagnostic system is fairly low.

By inventing a medical tool that uses existing technology—mobile phones—Ozcan has developed a medical tool that is both practical and economical. Therefore, it can be effectively almost anywhere. {#blank#}5{#/blank#}

A. Another reason that Ozcan's invention is important is that it is inexpensive.

B. Even though you may only have a simple infection (感染), you might die because of the delay.

C. People are trying to reduce the cost of this new medical tool.

D. Ozcan's simple, cost-effective tool might just save millions of lives around the world.

E. This tool has become much more popular all around the world.

F. You become very sick and must wait days until a mobile medical unit arrives to help.

G. As a result, they may diagnose illnesses incorrectly.
