How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question, as Tracy Smith reports in our Cover Story.

There are now more than a thousand genetic（基因的）tests, for everything from baldness to breast cancer, and the list is growing. Question is, do you really want to know what might eventually kill you? For instance, Nobel Prize-winning scientist James Watson, one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for Alzheimer’（老年痴呆症）.

“If I tell you that you have an increased risk of getting a terrible disease, that could weigh on your mind and make you anxious, through which you see the rest of your life as you wait for that disease to hit you. It could really mess you up.” Said Dr. Robert Green, a Harvard geneticist.

“Every ache and pain,” Smith suggested, could be understood as “the beginning of the end.”“That ’s right. If you ever worried you were at risk for Alzheimer’s disease, then every time you can’t find your car in the parking lot, you think the disease has started.”

Dr. Green has been thinking about this issue for years. He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s. It was thought that people who got bad news would, for lack of a better medical term, freak out. But Green and his team found that there was“no significant difference”between how people handled good news and possibly the worst news of their lives. In fact, most people think they can handle it. People who ask for the information usually can handle the information, good or bad, said Green.

请认真阅读下列短文，并根据所读内容在文章表格中的空格里填入一个最恰当的单词。

注意：请将答案写在答题卡上相应题号的横线上。每个空格只填1个单词。

??? One of the hottest buzzwords in China right now is no doubt tuhao, a sarcastic, light-hearted term referring to rich people of little education, bad taste or lacking self-awareness.

??? This is yet another example of smart Chinese Internet users applying their creativity to an aged phrase and giving it new life and meaning. The term, which literally means "country bully", has been around since ancient times, when it was used to refer to rich and powerful rural landlords.

??? However, the meaning of the word changed significantly when it was adapted a few years ago by Chinese players of the wildly popular computer game "World of Warcraft" to refer to rich players who spend big money buying powerful virtual weapons. Because they don't improve their skills by playing, these players are considered silly, uncultured, and unprofessional.

??? But that is not the end of tuhao's new life story. The renewed popularity of the term also coincides with（同时发生）the emergence（出现）of the Chinese "nouveau riche"一a generation of businessmen and women, property owners and entrepreneurs who have rapidly accumulated large amounts of wealth in recent years.

??? Similar to the many rags-to-riches stories in human history, many Chinese billionaires who are on the global rich list do not come from well-educated or prestigious（声望很高的） backgrounds. Rather, they achieved financial success through powerful connections, smart investments, and by riding out China's economic boom. Many of them don't shy away from throwing their money around, yet we are often reminded of their lack of manners, taste and cultural sensitivity.

??? As a result, a term that was popularized in the gaming world has now also been introduced into daily conversation.

??? Trend-, young Internet users, who see themselves as the opposite of tuhao一not wealthy, but well-educated and cultured一have further popularized the term by using it in various comic situations. For example, the phrase "let's be friends, tuhao," became hot after it appeared in an online joke about a conversation between a rich young man and a wise monk． `Vhen Apple released its much anticipated iPhone 5S in September, Chinese Internet users
