问题 Passage 1 [br]  
Well, yesterday we talked about long-term trading in the stock exchange. This morning I will focus myself on short-term trading. Recently, short-term trading has become more popular.
    Short-term trading especially refers to the one called day trading. Day traders seek to earn money from the daily changes in the price of a stock. Day trading is an extremely risky form of investing.
    It is possible to gain a large amount of money very quickly by day trading. Most day traders, however, lose money. This is because they don’t invest according to the common rules, but invest and earn money entirely by chance.
    I believe that, very soon, investors should be able to trade stocks twenty-four hours a day. Seven days a week. So my next lecture will focus on electronic dealing and its impact.
According to research by a U. S. institution, the time required for native English speakers to learn different foreign languages varies, depending on the complexity of the language, resources available, and student motivation.
    The easiest languages, including Spanish, French, Portuguese and Italian, require just 24 weeks of study, or 600 class hours, to achieve proficiency. These languages are the easiest because of their closeness to English.
    The most difficult languages are Arabic, Chinese, Korean and Japanese. They require, on average, 88 weeks, or 2,200 class hours, to reach speaking and reading proficiency.
    Each of the four "hard" languages is difficult for its own reasons. Arabic’s lack of vowels makes reading difficult for an English-speaking native, while Chinese requires the memorization of over a thousand unique characters.

选项

答案     根据美国一所机构的研究,以英语为母语的人学习不同的外语所需要花费的时间各有不同,取决于所学外语的复杂程度、可资利用的资源和学习动力。
    最容易学的语言包括西班牙语、法语、葡萄牙语和意大利语,只需要花24周,即600课时,就能熟练掌握,因为这些语言与英语相近。
    最难学的语言是阿拉伯语、汉语、韩语和日语,平均需要88周,即2200学时,才能熟练地使用这些语言说话和阅读。
    这四种“难学”的语言,各有各的难学之处。阿拉伯语没有元音,对于英语为母语的人来说,阅读起来就有困难,而学习汉语则需要记住1000多个独特的方块字。
