Appeal to Emotion（情感）
My childhood left three months ago on a plane to Austria.
It was a 36 day when my baby cousins moved away. My cousins were a fundamental part of my life; 37 they were not with me, they were on my mind. They brought back the untroubled days of my childhood, 38 games, adventures and silliness, but they also helped 39 me from an at-times selfish teenager into a responsible adult.
My aunt and uncle moved here from Boston with their 1-year-old daughter Yasmeen. They lived in an apartment on the side of our house and I was 40 to have our family, especially a baby girl, so close to us. Yasmeen had close friendships with each of my sisters, but I knew the one that 41 between us was the strongest. As she began to walk on her own and talk in full sentences, I realized my great 42 upon her. I noticed that she’d 43 some of my unpleasant actions, 44 with her mother after I had done the same. Yasmeen made me realize what being a good 45 really was.
When Maya was born, Yasmeen had a hard time 46 . She was jealous（妒忌）of the attention we all paid to her new younger sister, so I did my best to keep her company when she might have not been 47 . Once Yasmeen overcame her jealousy, she was able to 48 Maya’s presence, like we all did. I tried to take advantage of our times together, doing my best to 49 my schedule for my two favorite people.
My 50 with Yasmeen and Maya has taught me the importance of influential people. I know that I have helped Yasmeen and Maya 51 , but ―the babies‖ have had an even greater influence on my own life. They have shown me how to be a parent, a sister, a child, and most importantly, a friend. Our 52 has made me a better person—a more patient person, with the ability to 53 endless questions and spilled（洒）juice; an 54 person, able to have fun and be happy with others; a role model, 55 the babies ideas about right and wrong, and a compassionate person, able to forgive and love.
36. A. sad B. busy C. fine D. relaxing
37. A. until B. before C. when D. unless
38. A. against B. through C. besides D. for
39. A. lead B. challenge C. mature D. encourage
40. A. overjoyed B. embarrassed C. surprised D. afraid
41. A. ended B. started C. survived D. developed
42. A. pressure B. dependence C. mercy D. influence
43. A. doubt B. regret C. copy D. guide
44. A. debating B. arguing C. negotiating D. checking

B
―The 13th of June, 1325, I left Tangier, my birthplace, with the intention of making the pilgrimage（朝圣）to Mecca ... to leave all my friends, to abandon my home as birds abandon their nests.‖ So begins an old manuscript in a library in Paris—the travel diary of Ibn Battuta.
Almost two centuries before Columbus, this young Moroccan set off for Mecca, returning home three decades later as one of history’s great travelers. Driven by curiosity, he journeyed to remote corners of the Islamic world, traveling through 44 modern countries, three times as far as Marco Polo. Little celebrated in the West, his name is well known among Arabs. In his hometown of Tangier, a square, a hotel, a cafe, a ferry boat, and even a hamburger are named after him.
Ibn Battuta stayed in Mecca as a student for several years, but the urge to travel soon took over. In one adventure, he traveled to India seeking profitable employment with the sultan—the Muslim ruler of Delhi. On the way, he described his group being attacked in the open country by 80 men on foot, and two horsemen: ―… I was hit by an arrow and my horse by another, but God in his grace preserved me ...‖ In Delhi, the sultan gave him the position of judge, based on his previous study at Mecca. But the sultan had an unpredictable character, and Ibn Battuta looked for an opportunity to leave. When the sultan offered to finance a trip to China, he agreed. Ibn Battuta set off in three ships, but misfortune struck while he was still on the shore. A sudden storm grounded and broke up two ships, scattering （散播）treasure and drowning many people and horses. As he watched, the third ship, with all his belongings and slaves—one carrying his child—was carried out to sea and never heard from again.
After a lifetime of amazing adventures, Ibn Battuta was finally ordered by the Sultan of Morocco to return home to share his wisdom with the world. Fortunately, he agreed and wrote a book that has been translated into numerous languages, allowing people everywhere to read about his unparalleled journeys.
60. What can we learn about Ibn Battuta from the passage?
A. He had great interest in the Islamic world.
B. He returned to his homeland to write a book.
C. His journeys were less important than Marco Polo’s.
D. His journeys were very common for people of that time.
61. The Sultan of Delhi gave Ibn Battuta a position of judge because _______.
A. Ibn Battuta had studied in Mecca
B. Ibn Battuta had been a judge before
C. Ibn Battuta had worked as a translator
D. Ibn Battuta had traveled to many countries
62. Which is the best title for the passage?
A. The Learned Ibn Battuta
B. A Visitor to Mecca
C. The Travels of Ibn Battuta
D. Desire for Adventures
C
Culture and Cuisine
The United States is known for jazz and blue jeans. But travel to Paris and ask your average French citizen about American cuisine (烹饪) and he ’s likely to answer, ― McDonalds.‖ Ask the same thing of any American citizen on any American street and I ’m afraid you ’d get the same answer, or something close to it.
Hamburgers and hotdogs and fries are all fine, but with American malls and other outlets standardizing everything from clothing to food, the sad truth is that American cuisine is becoming more homogeneous ―all the same ―no matter where you live. True, many Americans are eating more varied foods these days, but these are largely the cuisines of immigrant groups, and they are quite likely to be affected by homogenization of American cuisine.
So what exactly is American cuisine? Well, to some extent it is a reflection of our melting pot culture, meaning that Europeans made huge contributions in the form of wheat, dairy products, pork, beef and poultry. But American cuisine also includes products that once were known only to the New World, including potatoes, corn, pumpkin, sweet potatoes, and peanuts.
The one region of the country where you still find all these things in daily use is the Deep South. The South lost the Civil War, but children of the southerners are winning the battle to preserve and advance their cooking traditions —and in this case one of the few cuisines can truly be called American, which is why we ’re pleased to have Low Country cuisine in this issue of food creation. That ’s right, grits and gravy are back in a big way in cities like Charleston and Savannah. Truth is, they never really left, but up until a decade ago Low Country cuisine was more common at home than in restaurants.
In fact, a large number of tourists now go to the lower Atlantic region in order to experience this extraordinary cuisine for themselves. Time will tell whether Low Country cuisine becomes popular in other regions of the country in the way that, say, Italian cuisine has, but it ’
s amazing and heartening to see one of our true cultural treasures enjoying renewed popularity in these increasingly homogeneous times.
63. According to the passage, American cuisine impresses people as being _______.
A. dull and changeless
B. rich and various
C. popular and delicious
D. disagreeable and unpleasant
Grits and Gravy
64. It can be seen that the writer feels regretful that _______.
A. cuisines of other countries play a more important role in America
B. American cuisine has become increasingly lacking in variety
C. American cuisine tends to vary because of immigration
D. American cuisine is being changed by foreign cuisines
65. From the passage, we know that grits and gravy _______.
A. were cooked with new materials after the Civil War
B. are gaining popularity in the south of America
C. were more popular over ten years ago
D. are seldom served in restaurants
66. What’s the writer’s attitude towards the renewal of Low Country cuisine in America?
A. Concerned and cautious.
B. Hopeless and doubtful.
C. Positive and supportive.
D. Critical and disapproving.
D
The Enigma（谜）of Beauty
The search for beauty spans centuries and continents. Paintings of Egyptians dating back over 4,000 years show both men and women painting their nails and wearing makeup. In 18th-century France, wealthy noblemen wore large wigs (假发) of long, white hair to make themselves attractive. Today, people continue to devote a lot of time and money to their appearance.
There is at least one good reason for the desire to be attractive: beauty is power. Studies suggest that good-looking people make more money, get called on more often in class, and are regarded as friendlier.
But what exactly is beauty? It’s difficult to describe it clearly, and yet we know it when we see it. And our awareness of it may start at a very early age. In one set of studies, six-month-old babies were shown a series of photographs. The faces on the pictures had been rated for attractiveness by a group of college students. In the studies, the babies spent more time looking at the attractive faces than the unattractive ones.
The idea that even babies can judge appearance makes perfect sense to many researchers. In studies by psychologists, men consistently showed a preference for women with larger eyes, fuller lips, and a smaller nose and chin while women prefer men with large shoulders and a narrow waist. According to scientists, the mind unconsciously tells men and women that these traits―the full lips, clear skin, strong shoulders―equal health and genetic well-being.
Not everyone thinks the same way, however. ―Our hardwire dness can be changed by all sorts of expectations—mostly cultural,‖ says C. Loring Brace, an anthropologist at the University of Michigan. What is considered attractive in one culture might not be in another. Look at most Western fashion magazines: the wom en on the pages are thin. But is this ―perfect‖ body type for women worldwide? Scientists’ answer is no; what is considered beautiful is subjective and varies
around the world. They found native peoples in southeast Peru preferred shapes regarded overweight in Western cultures.
For better or worse, beauty plays a role in our lives. But it is extremely difficult to describe exactly what makes one person attractive to another. Although there do seem to be certain physical traits considered universally appealing, it is also true that beauty does not always keep to a single, uniform standard. Beauty really is, as the saying goes, in the eye of the beholder.
67. People’s ideas about beauty _______.
A. have existed since ancient times
B. can be easily described
C. have little influence on a person’s success
D. are based upon strict criteria
68. In Paragraph 3, the babies in the study _______.
A. were rated for their appearance
B. were entered in a beauty contest
C. were shown photos of a group of college students
D. were able to tell attractive faces from unattractive ones
69. The underlined word ―traits‖ in Paragraph 4 probably means _______.
A. qualities
B. measurements
C. judgments
D. standards
70. We can learn from the passage that _______.
A. the ideas of beauty vary as people grow up
B. the search for beauty is rooted in lack of confidence
C. the standards for beauty are based on scientific researches
D. the understanding of beauty depends on cultural backgrounds
第二节（共5小题；每小题2分，共10分）
根据短文内容，从短文后的七个选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Virtual (虚拟) Teams
Virtual teams are a great way to enable teamwork in situations where people are not sitting in the same office at the same time. 71 This is particularly so for businesses that use virtual teams to build global presence, or need less common skills or knowledge from people who are unwilling to travel.
Virtual teams are governed by the same basic principles as traditional teams. 72 It is the way the team members communicate. They rely on special communication channels enabled by modern technologies, such as emails, faxes, and teleconferences, and alike. Due to more limited communication channels, the success of virtual teams is much more sensitive to the type of project the group works on, what people are selected, and how the team is managed.
73 One challenging case is the projects that rely heavily on integrated work. That is to
say, when each person’s work depends significantly on what someone else is doing at the same moment, like in a sports team, there is an ongoing heavy exchange of information in real time, and the tasks have to go through a strict order within a short time.
Not everyone can perform well in a virtual team environment. 74 Another important quality is communication skills. The team members must be able to communicate clearly and positively.
Managers of virtual teams need to pay much more attention to having clear goals, performance standards, and communication rules. People have various assumptions on what to expect from each other. 75
One of the biggest challenges of virtual teams is building trust between the team members. Trust is important for unblocking communication between members and increasing motivation of each person in the team. The issue of trust needs special attention at any stage of team existence.
A. Yet, there is one significant difference.
B. Not every type of project is suitable for a virtual team.
C. A virtual team can choose whatever project they like to work on.
D. The members must be self-motivated and able to work independently.
E. Such teams are now widely used by companies and organizations to cut business costs.
F. Members of virtual teams communicate quite well although they never meet face-to-face.
G. To avoid misunderstanding, clear rules that everyone understands and agrees on are necessary.

March 29th, Sunday Fine
Today some classmates and I served at Capital Library as volunteers. At 9 o’clock this morning, we gathered together at the gate of the library. After getting into the library, we were first trained by a librarian
on how to operate the computers to borrow or return books so that we could help readers later. Then, wearing the volunteer uniform and volunteer identity card, we got down to our work. Some of us helped with
shelving books and some offered assistance to the people who had problems with using the computers. All of us took our tasks seriously and tried to do them well.
Time passed quickly. Before we knew it, it was time to say goodbye to the staff. On the way back, we shared our feelings happily. When doing voluntary work, we did our part in helping others. Meanwhile, it promoted our social awareness. We all believe volunteering is rewarding and look forward to more of it.

典型案例四∣孙某诉北京朝阳区政府行政复议申请不予受 理决定案 行政机关负责人出庭应诉是行政机关参与行政诉讼活 动的行为，不属于行政复议法规定的具体行政行为。公民、法人或者其他组织针对行政机关负责人出庭应诉或不出庭 应诉提出的行政复议申请，依法不属于行政复议受理范围。基本案情2015年12月16日，北京市朝阳区人民政府（以下简称朝阳区政府）收到孙某邮寄的《行政复议申请书》，孙某提出的行政复议请求为：1、确认被申请人北京市公安局朝阳分局(以下简称朝阳公安分局)的行政机关负责人在2015年1月以来其诉朝阳公安分局的4起行政诉讼案件中拒不出庭应诉违法；2、安排其查阅被申请人朝阳公安分局提供的书面答复、证据、法律法规依据和其他有关材料；3、向其邮寄或由其当面领取该申请对应的《行政复议决定书》。朝阳区政府审查后认为孙某的申请不符合行政复议受理条件，于2015年12月23日作出《行政复议申请不予受理决定书》，决定不予受理孙某的行政复议申请。孙某不服，起诉至北京市第四中级人民法院，请求判决撤销朝阳区政府作出的《行政复议申请不予受理决定书》，责令朝阳区政府依法受理其提出的行政复议申请。裁判结果北京市第四中级人民法院经审理认为：公民、法人或者其他组织申请行政复议，
应当符合法定的申请条件，其申请事项应当属于行政复议受理范围。《中华人民共和国行政复议法》第二条规定，公民、法人或者其他组织认为具体行政行为侵犯其合法权益，向行政机关提出行政复议申请。该法第六条列举的行政复议受理范围亦是对相关具体行政行为不服申请行政复议的情形。本案中，原告孙某针对朝阳公安分局行政机关负责人不出庭应诉的行为向被告朝阳区政府申请行政复议，该行为系行政机关参与行政诉讼活动的行为，不属于行政复议的受理范围。原告孙某提出的要求被告朝阳区政府安排其查阅相关材料、向其邮寄或当面送达决定书的请求，属于原告在行政复议活动中所享有的权利，亦不属于行政复议范围。朝阳区政府认定孙某申请的行政复议事项不属于行政复议受理范围，并作出不予受理决定，认定事实清楚，适用法律正确。朝阳区政府于2015年12月16日收到孙某的复议申请，于2015年12月23日作出被诉决定书并向孙某邮寄送达，朝阳区政府在法定期限内作出不予受理决定，符合相关法律规定。据此，依据《中华人民共和国行政诉讼法》第六十九条之规定，判决驳回原告孙某的诉讼请求。原告孙某不服一审判决，提起上诉。北京市高级人民法院经审理，作出驳回上诉，维持一审判决的终审判决。典型意义行政机关负责人出庭应诉制度是行政诉讼法修改后增设的一项制度。行政诉讼法第三条第三款规定，被诉行政机关负责人应当出庭应诉，不能出庭的，
