第二部分：阅读理解（共两节，满分40分）
第一节（共15小题；每小题2分，满分30分）
阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。
A
I was stuck in O'hare airport on an extremely long weather delay, pacing up and down the waiting hall for some exercise, when I passed a wine bar for the twentieth time or so. But this time there was a young woman behind the piano, playing what I could only describe as absolutely beautiful classical music. She had not been there ten minutes earlier when I passed.
I sat down at an empty table for four very near the piano, and began to be warmed by her music and a bit by the wine! She played so effortlessly and with such beauty in every note. Her music immediately brought a huge smile to my face!
Soon, on a break, I thanked her and she told me that after a long day traveling, and now also facing long
weather delays, she "just needed to blow off some steam." Wow! Her version of blowing off steam was a gift to get.
As I sat alone drinking my wine, absorbed in this young woman's celebration of her musical passion, two women approached my table and asked if they could join me. I invited them to sit and we immediately began sharing our love of music and celebrating the happiness the piano music was bringing us at that moment.
The two women and I began to talk about our travels, life journeys, and passions. Hearing that unbelievable piano music, and then meeting such interesting women, who generously shared with me their wisdom, perspectives, and feelings of love for each other, was truly joyous. Faced with an 11- hour travel day -- to get what normally takes 45 minutes --could have been physically and emotionally exhausting. Rather, by accident of walking by a wine bar at the right moment, and having a couple of seats open at my table, my life was filled with joy.
I will cherish those moments for some time to come. This experience highlights (突出) the critical need in our lives to stop and listen to the music, to invite others to sit at your life table, to open yourself up to a stranger or two, sharing some of your deepest perspectives and experiences. Be open to noticing, absorbing, and also contributing to the joy around you!
What does the underlined phrase ―blow off some steam‖ in Paragraph 3 probably mean?
A. Reduce anger.
B. Relax herself.
C. Make full use of time.
D. Breathe fresh air.
How long was the author’s travel supposed to take without weather delay?
A. 10 minutes.
B. 20 minutes.
C. 45 minutes.
D. 11 hours.
How did the author feel about the experience in the airport?
A. Happy and meaningful.
B. Lonely but unforgettable.
C. Boring and meaningless.
D. Long and tiring.
The author writes the text in order to encourage people _______.
A.to make the acquaintance of strangers
B.to share your experiences with others
C.to communicate with others more often
D.to notice and enjoy the happiness around you
B
After years of planning and months of
expectations, the 2016 Summer Games finally began in Brazil on August 5. Over 10,000 athletes from 207 countries marched across Rio de Janeiro’s
Maracana stadium, proud to represent their
respective nations at the world’s most famous
sporting event.
The road to the Olympics, however, is not easy for any athlete. It has been particularly hard for Yusra Mardini, who is a member of the world’s first ―Olympic Refugee (难民)Team.‖ The 19-year-old always dreamed of swimming for Syria at the Olympic Games. However, in August 2015, after losing her home in the conflict that has involved Syria since 2011, she and her sister decided to flee the country. The sisters along with a few other Syrian nationals made their way to Turkey via Lebanon. They then set sail on a small boat to their final destination — Greece.
Unluckily, thirty minutes after leaving Turkey, the motor on the ship which was meant to hold six passengers but was instead carrying twenty, failed. Yusra, her sister Sarah, and the only two other strong swimmers aboard the boat had no choice but to dive into the ocean and use their superior swimming skills to push the boat and its passengers all the way to Lesbos, Greece – A journey that took three hours.
While her dream of representing her country was ruined, Yusra did not give up her desire to compete in the Olympics. In March 2016, she was one of ten athletes selected and funded by the Olympic Committee to form the first-ever ―Refugee Team.‖ International Olympic Committee president Thomas Bach believes that Yusra and her teammates, who have also had to flee their countries, ―Will show the world that despite the unimaginable tragedies they have faced, anyone can compete, anyone can contribute to society through their talent, skill, and strength of the human spirit.‖
What do we know about Yusra’s fleeing journey to Greece?
A. It was very hard.
B. It took three hours.
C. It was a failure.
D. It was very smooth.
What is the right order of the events related to Yusra?
a.She became a member of the world’s first ―Olympic Refugee Team‖.
b.She dreamed of swimming for Syria at the Olympic Games.
c.She lost her home.
d.She fled Syria to Greece with her sister Sarah and a few other Syrians
A. b, a, c, d
B. a, b, c, d
C. a, d, c, b
D. b, c, d, a
Thomas Bach’s attitude to Y usra is _______.
A. disapproving
B. tolerant
C. supportive
D. resistant
What is the best title for the text?
A. A Hard Road to the Olympic Games
B.Yusra Mardini — Refugee Team Swimmer
C.Yusra’s Strong Will to Compete in the Olympics
D.Athlete To Watch At The 2016 Rio Summer Olympics
C
While your pet fish may appear to be ignorant of your presence, chances are that it knows you extremely well and can probably even identify you from a crowd of human faces! At least, that is the conclusion reached by scientists the University of Oxford in the U.K. and the University of Queensland in Australia, following an extensive study of the archerfish (喷水鱼), a species of tropical fish that can be found all the way from India to Indonesia, the Philippines, and Australia.
The ability to distinguish between human faces is a complex task. That’s because we all have the same basic features —two eyes sitting above a nose and a mouth. It’s only the subtle diff erences that make humans distinct from one another. Since this requires a combination of both visual sense and memory, researchers had always assumed that it was a skill possessed only by those with complicated brains, i.e., humans, a few select animals —such as horses, cows, dogs, monkeys and some birds, like pigeons.
To test if this assumption was accurate, a team of scientists led by Dr. Cait Newport, Marie Curie Research Fellow in the Department of Zoology at Oxford University, decided to study fish. The aquatic (水生的) animals have small brains that lack the neocortex（大脑新皮层）, or neocortex-like structure, believed to help recognize the subtle differences between human facial features.
The team began by presenting four archerfish with images of two human faces. Initially, the fish spat randomly at both. However, they soon learned that pouring water at the one selected by the researchers earned them a food treat. After that, they focused primarily on that image. The researchers then took the experiment one step further, by introducing 44 other human faces to the mix.
To the researcher’s astonishment, the trained archerfish were able to recall the learned image almost 81% of the time. And this accuracy improved to 86% when the researchers made the identification even harder, by replacing the colored photos with a set of black and white images and hiding the shape of the head.
What is the conclusion of the study made by the scientists from the universities?
A. Some fish may ignore your presence.
B. Some fish can recognize your faces.
C. Some fish have complicated brains.
D. Some fish have large brains.
What does the underlined word ―it‖ in Paragraph 2 refer to?
A.The ability to distinguish between human faces.
B. A combination of visual sense and memory.
C.The ability of memorizing complicated things.
D.The ability of telling beasts from birds.
In the experiment, the researchers trained the archerfish _______.
A. by taking photos of fish
B. by improving people’s images
C. by rewarding them with food
D. by covering their heads

China has the 61 (distinct) of respecting the aged and cherishing the young. Contrary to popular belief, however, older people generally do not want to live with their children.
According to the latest 62 (analyze), about 80% of people 65 years and older have frequent contact with their children. About 75% of elderly parents 63 don't go to nursing homes live within 30 minutes for the sake of 64 (convenient).
However, 65 (mere) having contact with children does not guarantee happiness in old age. So far, some researchers 66 (find) that people who are most associated with their families have the lowest spirits. So it is more likely 67 poor health, not just family involvement, deepens spirits.
Increasingly, researchers have begun to look at the quality of relationships, rather than at the frequency of contact, between the elderly and their children. If parents and children come to a compromise 68 taking good care of children, they are likely to enjoy each other's company. Disagreements on such matters can turn out 69 (be) problems. If parents are angered by their daughter's divorce, dislike her new husband, and disapprove of how she is raising 70 grandchildren, chances are that they are not going to enjoy her visits.
