Each word can only be used once. Note that there is one word more than you need.The most difficult part of a Western-Chinese marriage is the cultural differences. The traditional Chinese culture is established on the Confucian philosophy, while the western culture is based on ancient Greek __41__. Cultural differences exist in almost every aspect and therefore __42__ also on relationships and marriage.From the traditional Chinese point of view, marriage is a relationship __43__ many aspects such as family, friends and relatives, while from the Western point of view, marriage is a contract signed between two people that is based on trust and love. Furthermore, Westerners’marriages __44__ more the independence and __45__ of the couple.That is why Westerners sometimes cannot understand why we Chinese need to support our relatives if we are asked to do so. Chinese need to maintain their “face” and “relations”. Even in a relationship, we are somehow still __46__ to our family and relatives. Our partner has to understand it and at least does not __47__ it.It is not easy to maintain Chinese-Western relationship. Cultural differences may result in __48__. Young Asian ladies are fond of western men because they believe they are more gentlemanly and in addition their appearances are more attractive. Western men may think Chinese ladies are gentler and more feminine.My suggestion for the cross-culture relationship is always trying to put yourself in other’s shoes: accepting rather than changing; always respecting your partner but clarifying your own red lines; showing your interest in his/her different culture and carefully commenting on it and so on.There are more and more cross-culture marriages __49__ recently. I would like to take this chance to sincerely wish them the very best in their love journeys.III. Reading Comprehension (50%)Section ADirections: For each blank in the following passages there are four words or phrases marked A, B, C and D. Fill in each blank with the word or phrase that best fits the context.A new research suggests that animals have a much higher level of brainpower than once thought. If animals do have intelligence, how do scientists measure it? Before defining animals’ intelligence, scientists defined what is not intelligence. Instinct is not intelligence. It is a skill __50__ into an animal’s brain by its genetic heritage(基因遗传). Tricks can be learned by repetition, but no real thinking is __51__. Cuing, in which animals learn to do or not to do certain things by following outside signals, does not demonstrate intelligence. Scientists believe that insight, the ability to use tools, and communication using human language are all __52__ measures of the mental ability of animals.When judging animal intelligence, scientists look for insight, which they define as a flash of sudden understanding. When a young gorilla(大猩猩)could not reach fruit from a tree, she noticed crates (木板箱) on the lawn near the tree. She __53__ the crates into a pyramid, then climbed on them to reach her __54__. The gorilla’s insight allowed her to solve a new problem without trial and error.The ability to use tools is also an important sign of intelligence. Crows(乌鸦)use sticks to pry (撬开)peanuts out of cracks. The crow __55__ intelligence by showing it has learned what a stick can do. __56__, otters(水獭)use rocks to crack open crab shells in order to get at the meat.Many animals have learned to communicate using human language. One chimp can recognize and correctly use more than 250 __57__ symbols on a keyboard. These symbols __58__ human words. An amazing parrot can __59__ five objects of two different types. He can understand the difference between the number, color, and kind of object. The ability to __60__ is a basic thinking skill. In addition, he seems to use language to express his needs and __61__. When ill and taken to the animal hospital for his fi rst overnight stay, this parrot turned to go. “Come here!” he cried to a scientist who works with him. “I love you. I’m sorry. Wanna go back?”The research on animal intelligence raises important questions. If animals are smarter than __62__ thought, would that change the way humans interact with them? Would animals still be used for food, clothing, or __63__ experimentation? Finding the answer to these tough questions makes a difficult __64__ even for a large-brained, problem-solving species like our own.50. A. developed B. admitted C. programmed D. injected51. A. inherited B. involved C. instructed D. intended52. A. realistic B. unusual C. accurate D. effective53. A. piled B. assembled C. supported D. divided54. A. potential B. reward C. standard D. top55.

For each of them there are four choices marked A, B, C and D. Choose the one that fits best according to the information given in the passage you have just read.(A)Brigham Young University students can now receive the unconditional love of dogs without breaking rules prohibiting pets in university housing.Jenna Miller started her company Puppies for Rent this summer in the Provo area as a way for students and others to rent puppies by the hour.The pups have been rented for first dates and surprise parties and by mothers rewarding their children. After signing a contract, customers can rent them for $15 an hour, $25 for two hours and $10 for each additional hour.Miller offers her seven puppies for playtime rentals, with each dog hand delivered straight to the customers’ door. Her lawyer brother helps her with legal contracts and fees. She now has four employees helping look after and deliver the animal.Carl Arky, spokesman for the Humane Society of Utah said his group is against the business.

Do you feel nervous when you sit a math exam? For most students, math can be tough but scientists have proved that math problems can actually trigger physical pain.Scientists came to this conclusion with an in-depth experiment, which was published in the Public Library of Science One journal. They began by finding out how much participants fear math. Those involved were asked a series of questions such as how they feel when they receive a math textbook or when they walk into a math lesson.Based on their answers, participants were divided into groups. One group was made up of people who were particularly afraid of math and participants in the other group were more comfortable with the subject.Both groups were then given either math tasks or word tasks. When a math task was going to come next, a yellow circle would appear but when a word task was soon to come, a blue square would be shown.Using a brain-scan machine, scientists noticed that whenever people from Group One saw a yellow circle, their brain would respond in a way similar to when their body is feeling pain. It was like the pain they would feel, for example, if they burnt their hand on a hot stove. But they reacted less strongly when they knew that they would be faced with a word task.However, scientists saw no strong brain response from people in the second group.Math can be difficult, and for those with high levels of mathematics-anxiety (HMA), math is associated with tension, apprehension and fear. “When you are really thinking about the math problems, your mind is racing and you are worrying about all the things that could go wrong,”explained Ian Lyons from University of Chicago, US, leader of the study. “The higher a person’sanxiety of a maths task, the more he activated brain regions associated with threat detection, and the experience of pain.”More interestingly, the brain activity disappeared when participants actually started dealing with the math tasks. “This means that it’s not that math itself hurts; rather, the anticipation of math is painful,” Lyons said.Based on the study, scientists suggested that things could be done to help students worry less and move past their fear of math, which might mean they perform better in tests.72. In the first stage, scientists ask participants some questions to _____.A. see whether math hurtsB. find out how much they fear mathC. observe how their brain responseD. test their endurance of pain73. The underlined word “the anticipation of math” is closest in meaning to _____.A. the attempt of learning mathB. the motivation to work out math problemC. the effort to understand mathD. the act of thinking about math74. Which is the best title for the passage?A. How to overcome math fear.B. Physical pain affects math performance.C. Math pain in your brain.D. Unknown truth about pain.75. What can be concluded from the experiment?A. The anticipation of math has no relation to students’ confidence in math.B. Moderate mathematic anxiety promotes students’ academic performance.C. Effective solutions have been worked out to lower students’ anxiety of math.D. Physical pain caused by HMA disappears in the process of doing math problem.Section CDirections:Read the following text and choose the most suitable heading from A-F for each paragraph. There is one extra heading which you do not need.Britain may be the most red-headed country in the world. About 1 to 2 percent of the world’s population has red hair, but in the UK the numbers are much higher, with 13 percent of Scots, 10 percent of the Irish, and 6 percent of people in England having red hair, according to the BBC.Scientists have tried to explain why some people have red hair for some time and now they may have found an answer: the dull weather in Britain. The human body needs vitamin D from sunshine, but unfortunately people living in Britain do not have enough of it because of its maritime climate. In fact, Britain gets even more cloud than countries in the far north of Europe. In Sweden, for example, the average daily hours of sunshine is 5.4. In Scotland it is only 3.1 hours.To deal with this, the DNA of people living in these areas has changed slightly; scientists call this a mutation. Originally, the coloring on our body is a mixture of two kinds of melanin – black melanin and red/yellow melanin, but with certain parts of DNA changed, the production of black melanin is suppressed while only red/yellow melanin is made. The result is red hair, light skin color, freckles and a greater sensitivity to sunlight.However, what’s more interesting is that the redhead DNA mutation is recessive, which means it is hidden and can often skip generations without showing. At least 1.6 million Scots carry a red-head gene mutation, and most are unaware that they do. This is why a person who does not have red hair can still produce red-haired children if he or she is a carrier of this special DNA.The research on red hair, like many areas of science, is contradictory. In 2002 researchers showed that redheads are more sensitive to pain, and need more anaesthetic during surgery than people with blonde or dark hair. However, in 2005 scientists found that a MCR1R mutation gives redheads a higher tolerance for pain. Research into these aspects of red hair genetics continues. Redheads should though be more careful about their exposure to sunlight as they are at an increased risk of contracting skin cancer. If you are a redhead, the advice is not to stay out of the sun, but to be careful about how much exposure you get, and to cover yourself with a high factor sunscreen.Section DDirections: Read the passage carefully. Then answer the questions or complete the statements in the fewest possible words.Pizza Hut lovers, you can now smell just like your favorite food. Pizza Hut launches its own perfume that smells like a fresh pizza pie. This is not a joke – although it started as one! While it might seem like an unusual venture for the brand famous for pizza, the company’s perfume is already available as a limited edition product.According to the Globe and Mail, the project started out as a joke by Grip Limited, an advertising firm that works with Pizza Hut in Canada, who asked the chain’s Facebook fans to imagine the pleasant smell of a fresh-delivered pie as a perfume – and to name it. Fans responded tothe idea so enthusiastically that Grip Limited decided to take the joke a step further and make the perfume a reality.A month and a half later, to celebrate that Pizza Hut Canada had gotten 100,000 fans, the chain's community managers announced that the first 100 people to message them would actually get a bottle of Pizza Hut perfume. And sure enough, the bottles were shipped to those 100 lucky fans before Christmas.Grip Limited isn’t the only company to attract attention with odd aromas(芳香). Four years ago, Burger King offered a $4 meat-scented body spray for men. Before that in 2006, Stilton created a perfume meant to mimic(模拟)the scent of blue cheese.Pizza Hut Canada has not announced any plans to make more of the perfume in the future. But the chain also said in the release that it’s possible the perfume could appear in stores in the future. (Note: Answer the questions or complete the statements in NO MORE THAN TEN WORDS)81. Some people consider the perfume a joke because they think Pizza Hut is a ______________.82. ___________________________ pushed Grip Limited to turn the joke into reality.83. Who are the lucky birds to get the perfume?______________________________________________.84. Why did Pizza Hut follow Burger King’s steps to release a perfume?______________________________________________.第II卷(共45分)I.
