For questions 1-7, choose the best answer from the four choices marked [A], [B], [C] and [D]. For questions 8-10, complete the sentences with the information given in the passage. Halloween On October 31st, dozens of children dressed in costumes knock on their neighbo rs’ doors and yell “Trick or Treat” when the door opens. Pirates and princesses, ghosts and popular heroes of the day all hold bags open to catch the candy or other goodies that the neighbors drop in. As they give each child a treat the neighbors exclaim over the costumes and try to guess who is under the masks. Since the 800’s November l st is a religious holiday known as All Saints’ Day. The Mass that was said on this day was called AllHallowmas. The evening before became known as All Hakkiwe’en, or Halloween. Like some other American celebrations, its origins lie in both pre-Christian and Christian customs. October 31st was the eve of the Celtic new year. The Celts were the ancestors of the present-day Irish, Welsh and Scottish people. On this day ghosts walked and mingled with the living, or so the Celts thought. The townspeople baked food all that day and when night fell they dressed up and tried to resemble the souls of the dead. Hoping that the ghosts would leave peacefully before midnight of the new year. Much later, when Christianity spread throughout Ireland and October 31st was no longer the last day of the year, Halloween became a celebration mostly for children. “Ghosts” went from door to door asking for treats, or else a trick would be played on the owners of the house. When millions of Irish people immigrated to the United States in the 1840s the tradition came with them. Today school dances and neighborhood parties called “block parties” are popular among young and old alike. More and more adults celebrate Halloween. They dress up like historical or political figures and go to masquerade parties(化装舞会). In larger cities, costumed children and their parents gather at shopping malls early in the evening. Stores and businesses give parties with games and treats for the children. Teenagers enjoy costume dances at their schools and the more outrageous the costume the better! Certain pranks (恶作剧) such as soaping car windows and tipping over garbage cans are expected. But partying and pranks are not the only things that Halloweeners enjoy doing. Some collect money to buy food and medicine for needy children around the world. Symbols of Halloween Halloween originated as a celebration connected with evil spirits. Witches flying broomsticks with black cats, ghosts, goblins (小精灵) and skeletons have all evolved as symbols of Halloween. They are popular trick-or-treat costumes and decorations for greeting cards and windows. Black is one of the traditional Halloween colors, probably because Halloween festivals and traditions took place at night. In

Model Test 3----参考答案部分

第三套模拟练习题参考答案作文参考范文 Information Security The human beings are stepping into the information society. The information industry develops very rapidly, so do the hackers, trick-playing teens, exploring children, fraudsters, and serious white-collar criminals. Thus, information security becomes an impending important issue. In case of information breach, the victims-----government department, an organization or an institution, or a company will inevitably suffer great or small loss. Government may be threatened with national security. Companies may lose opportunities to develop new projects. And the public’s and users’ confidence will be damaged. Then how to deal with this issue? Technology is only a partial solution to information security. What’s more important is that organizations and companies should promote the awareness on information security to its staff. However, since no system can ever be 100 percent secure, a prevention-only approach to information security management is not enough. Companies and organizations should adopt a dual approach to information security management by combing prevention and detection techniques. 快速阅读参考答案 1.

Model Test 1

Model Test 1 The shooting occurred Thursday in a lecture hall at Northern Illinois University in DeKalb , Illinois , north of Chicago. The gunman entered the hall dressed in black and carrying a shotgun and three handguns and began firing as students sought cover under desks. One student who escaped unharmed told reporter his life had changed as a result of what he experienced. Police say the gunman was Steven Kazmierczak,27, a former graduate student in Sociology at the school. Police say he purchased the shotgun and two of the handguns on Saturday, indicating he may have planned the attack in advance, but authorities have not determined a motive for the shooting. Kazmierczak had no criminal record and no history of mental illness. Under Illinois state law he would not been able to purchase a weapon legally if there had been a record of arrests or mental problems. But police say he stopped taking an unspecified medication recently and his behavior became erratic.
