‎2 Working the land 李仕才 ‎***阅读理解。‎ Those who claim bananas are fattening argue that bananas cause the body to make lots of insulin(胰岛素), and insulin causes fat growth.‎ How much insulin we produce is related to how fast food becomes sugar in our bloodstream. How can you know if food makes a lot of sugar quickly? The glycemic index(血糖指数), or GI rating tells us. Foods with GI scores above 75 are considered highGI foods, leading to faster sugar development. Bananas have a GI of 62, which is considered low.‎ Weight loss can be a struggle for anyone, but it is especially hard for diabetics(糖尿病患者). A study looked at how the starch from unripe bananas affected the weight of a group of obese diabetics. After four weeks of a diet high in bananas, diabetics lost significantly more weight than on a control diet. They also saw improvements in insulin sensitivity from the banana diet.‎ What’s more, bananas have been shown to cut risks of strokes, diabetes and cancers.(Bananas are the most powerful fruit for lowering the risk of kidney cancer.) Bananas are also a rich source of fiber, which has been shown to help weight loss. Bananas that still have some green on the skin are even higher in fiber.‎ Skins from green bananas can be taken and, after removing the stem and dark tip, cut into small pieces 2－3 inches long and 1/2 inch wide. These pieces can be made into a tea or added to a dish. When you eat the skins, be sure you are eating organic bananas. The flesh of regular bananas is low in pesticides, but the skins are not.‎ ‎【解题导语】　本文反驳了“吃香蕉会使人发胖”这一错误观点，告诉大家香蕉不会使身体分泌很多胰岛素而导致脂肪增加，相反，香蕉对身体健康有着诸多好处。‎ ‎1．What conclusion can we draw from Paragraphs 1 & 2?‎ 8‎ A．Bananas are likely to make people fat.‎ B．Insulin determines the amount of sugar.‎ C．LowGI foods can turn into sugar more slowly.‎ D．The faster the food becomes sugar, the less insulin.‎ C　解析：推理判断题。根据第二段中“How can you know if food makes a lot of sugar quickly? The glycemic index(血糖指数)．..faster sugar development.”可知，血糖指数高的食物往往能更快地转化成糖分，反之，血糖指数低的食物转化成糖分的速度较慢。故选C。‎ ‎2．What does the author say about bananas?‎ A．Including bananas in diets is good for health.‎ B．Bananas can cure people suffering kidney cancer.‎ C．Eating organic bananas can protect people from strokes.‎ D．Bananas’ abundant fiber improves insulin sensitivity.‎ A　解析：推理判断题。根据文章第三段中的“...diabetics lost significantly more weight than on a control diet. They also saw improvements in insulin sensitivity from the banana diet.”及第四段的“bananas have been shown to cut risks of strokes, diabetes and cancers...weight loss.”可知，香蕉可以帮助人们减肥，也能降低人们患中风、糖尿病及癌症的风险，由此可得出这样的结论：将香蕉列入日常饮食对人们的健康有益，故选A。‎ ‎3．What is discussed in the last paragraph?‎ A．The use of banana skins.‎ B．The benefits of banana skins.‎ C．The importance of banana skins.‎ D．The ways of choosing organic bananas.‎ A　解析：段落大意题。根据最后一段的内容尤其是“can be made into a tea or added to a dish”可知，本段主要讲的是香蕉皮的用途。故选A。‎ ‎4．In which section of a newspaper can we read this passage?‎ A．Education.　　　　 B．Health.‎ C．Culture. D．Science.‎ B　解析：推理判断题。纵观全文可知，香蕉不仅有助于减肥，‎ 8‎ 还能降低人们患中风、糖尿病及癌症的风险，而且香蕉皮也有用处。由此可知，本文最有可能出现在报纸的健康专栏。故选B。‎ ‎***语法填空。‎ Anyone who has had a longterm disease knows that recovering at home can be lonely. This can be __1__ (especial) true of children. They may feel __2__ (leave) out. Now, these children may have a hightech friend to help feel less lonely. A small robot may help children who are recovering from a longterm __3__ (ill). The robot like human beings takes their place at school. And their school friends must help carry the robot between classes and place the robot on their desks.‎ Through the robot, a child can hear his or her teachers and friends. He or she can also attend classes from wherever they are recovering—whether at home __4__ from a hospital bed. Dolva, one of the scientists who __5__ (be) concentrating on developing the robot, explains __6__ the robot AV1 works. She says from home, the child uses a tablet or phone to start the robot. __7__ (use) the same device, he or she can control the robot's movements. Inside the robot, there is a small computer linked __8__ a ‎4G network. The robot is __9__ (equip) with speakers, microphones and cameras, which makes communicating __10__ (easy).

　10.________ ‎ 篇章导读：本文是一篇说明文。病人由于长期患病在家，可能会感觉很孤独，对于孩子更是如此。本文介绍了一种机器人，可以帮助患病的孩子减少孤独感。‎ ‎1．especially　考查词性转换。设空处修饰形容词true，要用副词，故填especially。‎ ‎2．left　考查非谓语动词。leave out表示“遗漏；忽略”，与主语they构成逻辑上的动宾关系，所以用过去分词作表语。故填left。‎ ‎3．illness　考查词性转换。longterm为形容词，意为“长期的”，后应接名词。故填illness。‎ ‎4．or　考查连词。根据句中的whether可知应填or，whether ... or ... 为固定搭配，“无论……还是……”。‎ ‎5．are　考查主谓一致和动词的时态。本句中，who引导定语从句，先行词为the 8‎ ‎ scientists，故从句谓语动词应用复数形式；全文客观地介绍一种机器人，应用一般现在时。故填are。‎ ‎6．how　考查宾语从句的连接词。设空处引导宾语从句，作explains的宾语。分析句子结构可知，句中缺少状语，表“方式”，故用how连接该从句。‎ ‎7．Using　考查非谓语动词。句中已有谓语can control，因此，设空处应用非谓语动词；use与其逻辑主语he or she之间为主动关系，且非谓语动词在句中作方式状语。故填Using。‎ ‎8．to/with　考查介词。be linked to/with ... 为固定搭配，“与……连接”。故填to/with。‎ ‎9．equipped　考查动词的语态。be equipped with ... 为固定搭配，“装配有……”。故填equipped。‎ ‎10．easier　考查形容词的比较级。设空处在定语从句中作宾语补足语，而且本句暗含比较意义，应用形容词的比较级。故填easier。‎ ‎***完形填空。‎ 阅读下面短文，从短文后各题所给的A、B、C和D四个选项中，选出可能填入空白处的最佳选项。‎ I was a shy kid.Nothing seemed harder than talking to people.I didn't even like to answer the phone for fear that I'd have to talk to somebody I didn't know.‎ ‎__1__ ，at school I had to spend all day in the company of others.My __2__ was

former shyness is a gift，as I can __18__ people who feel discomfort when they talk to strangers.I still enjoy moments of being __19__.But I'm also glad I decided to make a __20__ in my life that had opened many doors and opportunities that I never knew existed.‎ ‎1．A.However B．Therefore C．Otherwise D．Besides ‎2．A.advice B．practice C．task D．escape ‎3．A.obviously B．simply C．quietly D．poorly

‎1．A　根据上下文可知，此处表示逻辑上的转折关系。然而，作者在学校里不得不和同学们相处。‎ ‎2．D　根据上文的“I was a shy kid”可推知，害羞的作者在学校用学习来逃避与人交流。‎ ‎3．C　与语境“by myself”呼应可推知，作者一个人安安静静地做功课。‎ ‎4．B　与语境“with good grades”呼应可推知，作者在学习上的付出得到了丰厚的回报，成绩突出。‎ ‎5．D　由“Eventually”的提示可推知，作者最终意识到了和朋友相处是有趣的。hang out“常去某处”。‎ ‎6．B　根据上文的“I was a shy kid”并结合“I found myself tonguetied”可推知，作者童年时代的害羞个性还存在。‎ ‎7．C　根据“I found myself tonguetied”可推知，和他人交流时沟通不顺畅是令人尴尬的。‎ ‎8．A　根据语境可知，作者在校园里注意到了一则让他感兴趣的广告。‎ ‎9．D　根据下文的“I had absolutely no background in radio”可推知，这是一则电台的招募广告。‎ ‎10．A　根据“I had absolutely no background in radio”并结合下文的“I didn't really want the job”可推知，作者因自己没有广播方面的背景而打退堂鼓，与下文的“I was even more terrified to discover that I had actually landed the job”呼应。‎ 8‎ ‎11．C　作者害怕与成千上万的听众交流，只想证明自己能够和面试官交谈。‎ ‎12．B　根据语境可推知，时间已经过去了两周。‎ ‎13．D　根据上文可知，这项工作需要与成千上万的听众交流，这对作者来说有一定的挑战性，且与语境“but I grew to enjoy it”形成呼应。‎ ‎14．A　与上文的“and the idea of talking to thousands of listeners __10__ me”呼应可推知，此处表示作者给听众播放音乐。‎ ‎15．B　与语境“answering their

shyness is a gift”可推知，作者能够理解那些和他相同的人。relate to“理解，认同”。‎ ‎19．A　根据上文的“My former shyness is a gift”可推知，作者仍旧喜欢独处。‎ ‎20．C　根据语境可推知，作者通过做电台工作有了重大改变，从而人生有了更多的可能性。‎ ‎***短文改错。‎ Mistakes are unavoidable in life. But attitudes towards it may make a difference.‎ ‎ I still remember how my spoken English was improved. In a beginning, I always kept silent in our oral class to avoid make mistakes.Before long my teacher got to know about my situation.He encouraged me to speak out that I thought. Whenever I made mistakes and felt discouraging, my teacher and my classmates would help me figure out how I must avoid them.I also joined in an English club to get more chances to speak. Practice made perfect. Now I can talk fluent in English.‎ ‎ Just as the saying goes, “Every bean has its black.” Don't afraid of making mistakes.

Now I can talk in English.‎ ‎ Just as the saying goes, “Every bean has its black.” Don't afraid of making mistakes. Learn from mistakes, and success is just waiting for us.‎ 难项分析：‎ 第四处：that→what　考查宾语从句。分析该句结构可知，该句为含有宾语从句的主从复合句，what既作宾语从句的引导词，也作从句中及物动词thought的宾语，而that在宾语从句中不作成分，故将that改为what。‎ 第六处：must→could　考查情态动词。根据语境可知，该句表示“帮我弄明白怎样才能避免这些错误”，作者回顾提高英语口语的过程，是过去发生的行为，故用could do sth.。‎ 第十处：afraid前加be　考查祈使句。分析句子结构可知，该句为祈使句，afraid为形容词，故afraid前加动词原形be。‎ ‎***‎ ‎ ‎ 8‎
