The smell ruined my appetite, and I pushed the dish away. “Just give it a try！” my grandmother said. Holding my breath, I unwillingly took a bite. To my surprise, the tofu beneath the fried surface was warm, soft, and mouth-watering. From then on, whenever I visited my grandmother, I would rush to the kitchen for the stinky tofu with excitement, and it became my favorite dish. Along with the stinky tofu, I would meet Uncle Chan on every visit, who was an unfriendly man with Down's syndrome (唐氏综合征) in my eyes. Whenever he came into view, I would run away in fear. However, one day, my view about my uncle changed. I was just getting out of bed when I heard soft steps approaching. It was my uncle. My muscles tightened. He slowly sat next to me and touched my face gently, as a mother stroked (轻抚) a baby. A wide smile spread over his face. How beautiful his smile was! I could not help but smile back. My fear disappeared gradually, and my muscles relaxed. For the first time, I could see kindness and warmth in his eyes. My uncle is similar to stinky tofu which made me keep my distance at first but felt the warmth inside later. I learned that he has good nature deep inside. Some people tend to look down upon disabled people and regard them as unfit for a normal life. As I was unable to see through the surface of the tofu, these people are unable to see through the surface of prejudice. As a result, they judge the disabled at a single glance. The outside and the inside of the stinky tofu exist as two extremely different worlds. Perhaps that is what makes it such a tasty dish. What's more, it offers a valuable lesson: never judge people at first glance, for true beauty comes from the inside. [语篇解读]　本文是一篇夹叙夹议文。作者通过爱上吃臭豆腐及转变对患有唐氏综合征的叔叔的态度这两件事认识到不能以貌取人，内在美才是真的美。 2 3 1 4 1．Why did stinky tofu become the author's favorite dish? A．It was related to the family tradition. B．Grandmother encouraged him to try it. C．It tasted much better than it smelled. D．His appetite for food increased. 答案：C 细节理解题。根据第三段中的“To my surprise, the tofu beneath the fried surface was warm, soft, and mouth-watering.”可知，在品尝了臭豆腐之后，作者发现油炸臭豆腐的表面之下又热又软，令人垂涎欲滴。因此，臭豆腐成了作者最喜欢的菜。故选C。 2 3 1 4 2．What caused the change of the author's attitude towards Uncle Chan? A．Uncle Chan's encouraging words. B．Uncle Chan's love for a little baby. C．Uncle Chan's friendliness towards the author. D．Uncle Chan's help in waking up the author. 答案：C 2 3 1 4 细节理解题。根据第五段中的“He slowly sat next to me...A wide smile spread over his face.”以及“For the first time, I could see kindness and warmth in his eyes.”可知，当叔叔对作者表现出友善时，作者对他的态度发生了改变。故选 C。 2 3 1 4 3．Why did the author make a comparison between stinky tofu and his uncle? A．To describe his childhood memory. B．To analyze family relationships. C．To introduce a traditional Chinese dish. D．To highlight the inner beauty of Uncle Chan. 答案：D 2 3 1 4 推理判断题。根据倒数第三段内容可知，作者认为叔叔和臭豆腐有相似之处。一开始叔叔的唐氏综合征令作者与他保持距离，但后来作者了解到，在内心深处，叔叔是善良的。据此可推知，作者将两者作比较是为了突出叔叔的内在美。故选 D。 2 3 1 4 4．What does the author mainly want to tell us in the text? A．You are what you eat. B．Blood is thicker than water. C．A person's taste changes over time. D．We shouldn't judge people by their appearance. 答案：D 2 3 1 4 主旨大意题。根据全文尤其是最后一段内容可知，作者讲述自己爱上吃臭豆腐的经历以及自己对叔叔态度变化的过程，是想告诉我们不能以貌取人的道理。故选 D。 2 3 1 4 Ⅴ.语法填空 [语篇解读]　本文是一篇说明文。受各种因素的影响，人们对美的评判标准不一样，但内在美才是真正需要我们认真领会的。 There are no precise standards that can be used to judge what is beautiful.As anthropologist (人类学家) Margaret Mead once put 1. ，“Criteria and ideas of beauty change over time.” Nowadays，some costumes and actions once 2. (regard) as beauty in the 19th century are not considered healthy or attractive，while something 3. (fashion) now had different functions in the past. 1．考查代词。固定句式as sb.put(s) it 意为“正如某人所说”。故填 it。 答案：it 2．考查非谓语动词。分析句子结构可知，“once 2. (regard) as beauty in the 19th century”为后置定语，修饰some costumes and actions，因 regard与some costumes and actions之间是逻辑上的动宾关系，应用过去分词。故填 regarded。 答案：regarded 3．考查词性转换。结合空前的something可知，此处要用形容词作定语。故填fashionable。 答案：fashionable There is no consistent view 4. beauty，as beauty is influenced by culture and it is even 5. (whole) different in the eyes of different people.In some countries，young women follow slimming diets to lose extra kilos in 6. (prepare) for their wedding days.In other cultures，7. (look) thin is not what a woman desires at all. 4．考查介词。view后常跟介词on/about，表示“对……的观点/看法”。 答案：on/about 5．考查词性转换。根据空后的形容词 different 可知，空处需用副词修饰形容词。故填 wholly。 答案：wholly 6．考查词性转换。in preparation for...意为“为……做准备”，为固定用法。故填preparation。 答案：preparation 7．考查非谓语动词。分析句子结构可知，空处为非谓语，“7. (look) thin”在句中作主语，表示一般性的动作。故填looking。 答案：looking However different，one thing is certain—it is inner beauty 8. requires us to truly see.Physical beauty，that is to say，9. (accompany) by an attraction to something deeper within a person，which can be found in a wide range of personal 10. (quality). 8．考查强调句型。分析句子结构可知，此处为强调句型，被强调部分为inner beauty。故填 that。 答案：that 9．考查动词的时态、语态和主谓一致。此处描述客观事实，用一般现在时；physical beauty和accompany之间是被动关系，用被动语态；又因句子主语physical beauty为不可数的抽象名词，所以谓语动词用单数。故填is accompanied。 答案：is accompanied 10．考查名词复数。联系语境并根据空前的“a wide range of”可知，此处表示复数意义，quality在此作“(尤指好的)性质，品德”讲，为可数名词，空处应用名词复数形式。故填qualities。 答案：qualities $$
