A Thanksgiving Day story in the newspaper told of a school teacher {#blank#}1{#/blank#} asked her class of first graders to draw a picture of something they were thankful for. She {#blank#}2{#/blank#} (think) of how little these children from poor neighbourhood actually had to be thankful for. But she knew that most of them would draw pictures of turkeys or tables full {#blank#}3{#/blank#} food. The teacher was taken back with the picture Douglas handed in—a small childishly hand!

    But whose hand? The class was {#blank#}4{#/blank#} (puzzle) by the abstract drawing. “I think it must be the hand of God {#blank#}5{#/blank#} brings us food,” said one child, “a farmer,” said another, “because he feeds turkeys.” Finally, when the others were at work, the teacher {#blank#}6{#/blank#} (bend) over at Douglas' desk and asked whose hand it was. “It's your hand, Teacher,” he said in a low voice.

    She remembered that {#blank#}7{#/blank#} (frequent) at break she had taken Douglas, a small lonely child, by {#blank#}8{#/blank#} hand. She often did that with the {#blank#}9{#/blank#} (child). But it meant so much to Douglas. Perhaps this was everyone's Thanks-giving, not for the material things {#blank#}10{#/blank#} (give) to us but for the chance, in whatever small way, to give to others.

    Believe it or not, have you ever noticed that you feel happier and more relaxed after you eat bread, pasta or fruit? Do you find that you are more energetic and awake after eating yogurt or beans? These things are not accidents. Food affect {#blank#}1{#/blank#} we feel more than we think. Scientists researching {#blank#}2{#/blank#} (it) effect on our moods are beginning to understand that we can influence our feelings with what we eat.

    Although our moods relates {#blank#}3{#/blank#} having various foods, it is not quite as simple as choosing the foods for the right occasions. If that {#blank#}4{#/blank#} (be) the case, athletes would not eat a lot of carbohydrates before a race.

    Another chemical {#blank#}5{#/blank#} (connect) with our mood is caffeine, which {#blank#}6{#/blank#} (find) in coffee, chocolate and many types of tea, is perhaps {#blank#}7{#/blank#} worst thing you can have when you are feeling stressed.

    Of course, {#blank#}8{#/blank#} (enjoy) a nice meal with friends, whatever we eat, can also impact our spirits. Being with friends and family plays a big part in experiencing happiness.

    Most {#blank#}9{#/blank#} (important), though, remember the following old rule: try to eat different food, {#blank#}10{#/blank#} not too much.

    Brave and {#blank#}1{#/blank#}(intelligence), the tiny mouse from the US cartoon series Tom and Jerry is loved and remembered by fans worldwide.

    Recently, scientists from Britain and Canada have created super-clever mice by {#blank#}2{#/blank#}(change) a single gene (基因). In the study, {#blank#}3{#/blank#}(research) changed one of the mice's genes to stop the PDE4B enzyme (酶), a substance found in the human brain, {#blank#}4{#/blank#} working.

    After that, they ran several tests on the {#blank#}5{#/blank#}(behave) and found they tended to learn{#blank#}6{#/blank#}(fast), remember events for longer and {#blank#}7{#/blank#}(solution) difficult problems better than normal mice. The mice also suffered less anxiety (焦虑) and showed {#blank#}8{#/blank#} fear of cats, their natural enemy.

    A team from the UK's Leeds University is now trying developing drugs (药品){#blank#}9{#/blank#} could block the PDE4B enzyme. {#blank#}10{#/blank#}(hope), the drugs could help with treatments for brain conditions such as Alzheimer's disease (老年痴呆症).

    In elementary school, George wasn't {#blank#}1{#/blank#} (exact) popular, but he always had a couple of really good friends. In middle school, he was really good at science and math. {#blank#}2{#/blank#} most kids were going to the movies on weekends, George preferred to design his own special projects. He dreamed of owning his own technology company someday. When George got to high school, some of the other students made {#blank#}3{#/blank#} of him for being into books and computers. This made George very upset, but he tried not to let anything keep his dream from {#blank#}4{#/blank#} (achieve). George got excellent grades and was admitted {#blank#}5{#/blank#} both Harvard and Yale, but he decided to go to Stanford {#blank#}6{#/blank#} there were many opportunities for people {#blank#}7{#/blank#} wanted to work in Silicon Valley. This was the first time George {#blank#}8{#/blank#} (feel) accepted by the people around him. He took many computer classes, and kept designing his own projects on weekends. During the summer months, he would take extra classes, and he ended up {#blank#}9{#/blank#} (graduate) a year early. He took a job {#blank#}10{#/blank#} a computer programmer at Apple. After five more years there, George left to start his own company, finally realizing his childhood dream.
