阅读下列短文,根据短文信息完成文后表格,每空一词。

    Last year, I did not like my English class. Every class was like a bad dream. The teacher spoke very quickly and I couldn't understand her most of the time. I was afraid to ask questions because I didn't know how to read the words correctly. I just hid behind my textbook and never said anything in class.

     Then one day I watched an English movie—Toy Story. I fell in love with this exciting and funny movie. So I began to watch other English movies, too. Although(尽管)  I understood I could get the meaning by listening for just the key words. I found out that listening to something interesting is the secret to the language learning. I also learned some useful sentences like “It's a piece of cake”or “It serves you right. I did not understand these at first. But because I wanted to understand the story, I looked them up in a dictionary(字典).

    Now I really enjoy my English class. Do you want to learn English like this?

阅读下列材料,回答问题。

材料一 公元前6 世纪,梭伦对国家政权机构进行了改革,使公民大会成为国家最高权 力机关,负责审议并决定一切国家大事。所有合法公民均有参与权、知情权、发言权、选举 权和被选举权。公元前6 世纪末,克利斯提尼创立新的五百人会议(作为常设机构),每部落 抽签选出50 人参加,议员名额依各居住区公民人数按比例分配。当选议员可以连选连任, 但一位公民一生只能担任两届议员。 (苏格拉底认为雅典民主政体的)“根本缺陷,在于它不要求其领导者具有任何特殊的知 识,它将社会的命运委之于缺乏真知灼见的人们的手中。”

 ——《雅典民主政治初探》

材料二 雅典的法庭不设法官,只设主持官,负责组织审判并维持法庭的秩序,判决的 权力则在陪审团。陪审团成员从公民群体中抽签产生。其例为:每年初公民自愿报名而后抽签从自愿者中挑选出六千人,作为当年陪审团成员。如遇有法庭开庭之日,城邦官员事 先根据案件大小确定审判每桩案件所需陪审团规模,从五人到二千人不等,然后从六千名陪 审团成员中抽签选出当日所需陪审员总人数。开庭之前,再以抽签的方式将这些陪审员分配 到不同的法庭,审理不同的案件。
