Once upon a time, a powerful king commanded his men {#blank#}1{#/blank#} (build) a public arena where crime was punished or innocence(无罪) was decided. When a person {#blank#}2{#/blank#} (accuse) of a crime, his future would be judged in the public arena.

    Usually the king sat high up on his chair. He gave {#blank#}3{#/blank#} sign and a door under him opened. The accused person stepped out into the arena. Opposite the king {#blank#}4{#/blank#} (be) two doors. The person on trial(审判) had to walk {#blank#}5{#/blank#} (direct) to these doors and open one of them. He could open whichever door he pleased. If the accused man opened one door, out came a hungry tiger, the {#blank#}6{#/blank#} (fierce)(凶猛的) in the land. The tiger immediately jumped on him and tore him into pieces as {#blank#}7{#/blank#} (punish) for his guilt. The case of the suspect was thus decided. {#blank#}8{#/blank#} , if the accused opened the other door, there came a woman. To this lady he was immediately married, in honor of his innocence.

    This was the king's method of {#blank#}9{#/blank#} (carry) out justice. Its fairness appeared perfect. The accused person could not know which door was hiding the lady. He opened either as he pleased, without knowing {#blank#}10{#/blank#} he was to be killed or married

    If you want to find out a piece of information about anything, the best place to search {#blank#}1{#/blank#} it is Wikipedia. This online encyclopedia is {#blank#}2{#/blank#} (write) by thousands of people around the world. Anyone can add or change the information if he or she finds it not correct or not well written. In this way, people who know a lot about a certain subject can write about it {#blank#}3{#/blank#}  {#blank#}4{#/blank#} they are not university professors.

    What is more, Wikipedia includes articles written in about 253 languages. This fact makes it {#blank#}5{#/blank#} of the few websites (网站) on the Internet that are truly international. It was started in 2001 by Larry Sanger and Jimmy Wales, as a free online English-language encyclopedia project. By April 2008, over 10 million articles {#blank#}6{#/blank#} ( put on) Wikipedia. A quarter of the articles are in English. Wikipedia is also a place {#blank#}7{#/blank#} people can find the latest news.

    However, Wikipedia has its own problems. There have been many complaints that some of the information on Wikipedia is not accurate and some important subjects are not included. This has led to arguments between the writers of the articles. The people {#blank#}8{#/blank#} (run) Wikipedia say that the accuracy of the information is improving and that it is one of the top 20 visited websites on the Internet.

    So, if you are looking for some information, why not {#blank#}9{#/blank#} (try) Wikipedia?

Their research, recently {#blank#}3{#/blank#}( publish) in the journal Memory, suggests that reading out loud to yourself can increase your recall skills {#blank#}4{#/blank#}up to 15%.

    In the study, scientists asked 95 participants to test four {#blank#}5{#/blank#}(method): reading, silently, hearing someone else read, reading aloud and listening to a recording of oneself reading. Their result? The people{#blank#}6{#/blank#}read the information out loud showed the best retention(保持)rates—about 15%{#blank#}7{#/blank#}(high) in learning speed, in fact. You may want to add these brain-boosting foods that can improve memory to your diet, too.
