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.

E. It needs exercise.

F. You are such a smart child.

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

    Experts say moods are feelings that tend to become fixed, influencing one's outlook for hours, days or even weeks. That's great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.

    Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology（药理学）offers a lot of tranquilizers（镇静剂）. What many people don't realize, however, is that scientists have discovered the effectiveness of several non – drug methods to set you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don't head for the drug – store but try the following methods.

    Of all the mood – altering self – help techniques, aerobic exercise（有氧运动）seems to be the most efficient cure for a bad mood. "If you could keep up the exercise you'd be in high spirits," says Kathryn Lance, author of Running for Health and Beauty.

    Researchers have explained biochemical and various other changes that make exercise compare favorable to drugs as a mood raiser. Physical work such as housework, however, does little. The key is aerobic exercise —running, cycling, walking, swimming or other repetitive and sustained activities that increase the heart rate, increase blood circulation and improve the body's use of oxygen. Do some of the activities for at least 20 minutes a session three to five times a week.

    On November 14, 1902, President Theodore Roosevelt was on a hunting trip in Mississippi while trying to settle a line(边界) problem between Mississippi and Louisiana. Being an expert outdoorsman, he liked to hunt large animals.

    However, his hunt was going poorly that days, and he couldn't seem to find anything worthy of firing his gun. His followers, trying to help him, caught a Louisiana black baby bear for the President to shoot, but he refused. The thought of shooting a bear that was tied to a tree did not seem sporting, so he spared the life of the baby bear and set it free.

    A famous political cartoonist for the Washington Star, Mr. Clifford Berryman, drew a cartoon titled. Drawing the Line in Mississippi, which used the story of the President refusing to shoot the bear.

    The cartoon in the Washington Star showed Teddy Roosevelt, gun in hand, with his back turned on a pretty baby bear. Morris Michtom, owner of a Brooklyn toy store, got the idea from the cartoon and make a toy bear. Planning to use it only as a display, he placed the bear in his toy store window, and next to it placed a copy of the cartoon from the newspaper. To Michtom's surprise, he was surrounded by customers eager to buy it. He asked for and received President Roosevelt's permission to use his name for the bears that he and his wife made, and the Teddy Bear was born! Michtom soon made Teddy bears by the thousands. The money from selling Teddy bears made him, in 1903, form the Ideal Toy Company.

    Compared with solar and wind energy, which are booming, tidal (潮汐的) power is a loser in the clean - energy competition. But if you did want to build a tidal power station, there are few better sites than the mouth of the River Severn, in Britain. Its tidal range, the difference in depth between high and low tides, of around 15 metres is among the largest in the world.

    Engineers and governments have been toying with the idea since at least 1925. But none of the suggested projects has materialised. Price is one objection. A study thought that tidal energy might cost between ￡216 and ￡368 ($306 - 521) per MWh of electricity by 2025, compared with ￡58 - 75 for seagoing wind turbines (轮机) and ￡55 - 76 for solar panels. Environmentalists also worry that any plant would change the tides, making life harder for wildlife.

    An engineer called Rod Rainey thinks he has a way around both problems. He plans to replace the conventional turbines of previous plans with a much older technology. Specifically, he plans to span (横跨) the river mouth with a line of water wheels. This is a design that dates back to the early days of the Industrial Revolution. Examples can be found fixed to the sides of old watermills (水磨).

    But there would be nothing old - fashioned about Mr Rainey's wheels. Thirty metres high and sixty wide, they would be made from ordinary steel. Two hundred and fifty of them, along with the supporting structures, would be floated into place and secured to the seabed, creating a line 15km long. Together, they could supply power at an avenge ate of 4GW. That is about as much as two biggish nuclear power stations would manage. Substituting one of the wheels with a set of locks would provide a shipping channel about twice the width of Panama Canal, permitting upstream ports such as Avonmouth and Cardiff to continue operating.

Improve your memory

    Some people often complain about their poor memory. Actually there are several ways to keep your memory sharp. This article will show you some simple tips.

    ♦{#blank#}1{#/blank#}When you say these things, you begin to plant the thought in your mind and it may become true. Tell yourself you can remember anything as long as you put your mind to the task. You will see an improvement in your memory.

    ♦{#blank#}2{#/blank#} If you have trouble remembering phone numbers or other blocks of numbers, it can be really helpful to try this method. If you remember them in smaller groups, like two or three digits (数字), it will also be much easier to remember the number.

    ♦ Be sure to see a doctor if you really are losing your memory. A poor memory can be a sign that you are in low spirits. {#blank#}3{#/blank#}

    ♦ Playing games also helps improve your memory. Any type of games that involves remembering things is wonderful. Try and rem{#blank#}4{#/blank#}ember it when you have nothing better to do. A useful tip for anyone interested in games is to often work on solving word puzzles and similar types of games.{#blank#}5{#/blank#} Not only will your memory probably improve, you will also have a great deal of fun.

A. Take a right attitude.

B. Remember numbers in small groups.

C. Stop telling yourself you have a weak memory.

D. If you don't know your condition, you won't go to hospital.

E. If you don't like games, you can go over a list of "to-do things".

F. If so, treating it could be the key to getting your memory back.

G. Such games use the same skills to remember facts and help keep the mind sharp.

Recently, I carried out an investigation to discover what it was that prevented people from journalling. {#blank#}1{#/blank#} So, today, I want to introduce a very simple tool — The MicroMOVEment Wheel. It will help you pick up your journal even at times when you really don't feel like it.

{#blank#}2{#/blank#} She describes creating this method so she could use it as a creative planning tool for her writing projects and goals. While it was originally aimed at writers, you can use this technique to help you complete any project in a fun and creative way.

{#blank#}3{#/blank#} Here's how it works. Take a blank sheet of paper and draw a large circle, and then another smaller circle in the middle, In the center circle, write down what you are inspired to achieve. Remember, journaling does not need to feel like a chore in your day. So come up with descriptions for your journalling that are inspiring and energizing. {#blank#}4{#/blank#} These are what SARK refers to as the MicroMOVEments. Each MicroMOVEment is five minutes in length, So, in the case of journalling, that would represent a minimum of up to five minutes of journalling in one sitting, on any given day.

Let's say you're new to journalling. By setting aside five minutes out of your day, you could write one word in your notebook that sums up a feeling or an experience. {#blank#}5{#/blank#} The idea of the MicroMOVEment is to create easy steps to get your journal writing or writing projects moving. When you keep the steps small, it will become doable and achievable.

A. Next, divide the rest of the circle into eight equal parts.

B. It is the brainchild of international bestselling writer SARK.

C. There are no hard-and-fast rules when it comes to journalling.

D. Where to start and not having enough time were amongst the top responses.

E. Daily tasks such as sweeping and washing are time-consuming and laborious.

F. Then, list any associated words, images or thoughts that are generated by the word.

G. The medicine with this approach is breaking your actions down into the tiniest steps.
