I attended a writer's group to get feedback (反馈) on my book. But there were so many people there that the discussion was limited. After getting home, my 13-year-old son asked me to read one chapter to him. So I read the chapter about spending my pocket money as a nine-year-old child.

The story took place at a lunch counter, where I dreamed of ordering a banana split Colorful balloons were hung above the counter and a sign said“Pop(使爆裂) a balloon and pay I cent to 63 cents for a banana split! "As I was given only 50 cents for cleaning the doghouse, I didn't dare to ask my parents for any more pocket money without doing more work. So I kept my wish to myself.

Frankie listened carefully, as I read the final sentences of the chapter, "I watched as others selected a balloon to pop and dreamed about the opportunity to take my chance. But it never happened."

The next morning, Frankie led me to the kitchen. I couldn't believe my eyes. The table was covered in a pile of balloons. Frankie handed me 50 cents and a fork. "Pop one!" he urged. With tears in my eyes, I broke one. A piece of paper fell out of the balloon.

"What does it say, Mom?" Frankie asked. "Fifty cents," I whispered, too choked to speak loudly. Frankie asked," Well, do you have 50 cents?" I handed him the money. "OK!" Then Frankie pulled out a banana split from the refrigerator.

I hugged Frankie hard. We took turns popping the other balloons until I finally got the I-cent balloon. It was a long-time coming but worth the wait.

It hit me that the first step in making any wish come true is to give it a voice.

24. The author read the chapter to Frankie because______.

A. she wanted to get feedback from Frankie

B. Frankie asked the author to read it to him

C. she was used to telling a bedtime story to him

D. Frankie had a strong desire for knowledge

25. What can we infer about the author from the second paragraph?

A. She spent money wisely when she was a kid.

B. She had enough money to do whatever she liked.

C. She earned her pocket money by doing housework.

D. She had no close friends to share her secret wish.

26. Seeing what Frankie did for her, the author felt______.

A comfortable and happy

B puzzled and excited

C awkward and satisfied

D. surprised and moved

27. The author learned that______.

A. it is important to express one's wishes

B. it is comforting to have a kid around

C experiences in childhood affect us later in life

D. wishes can come true by just voicing them

C

Next time you go shopping, keep in mind that there may be hidden cameras analyzing your habits. According to a 2015 survey of 150 managers from Computer Services Corporation, a quarter of British shops use facial recognition software to collect data on shopper behavior.

With concerns that face-recognition cameras“are kind of invasive(冒犯的)”, British analysis firm Hoxton Analytics has come up with a new way of measuring footfall (客流)—by filming people's shoes. The technology can collect a large amount of personal information. "We have cameras at 50 cm off the ground and they point down so they are less invasive than facial recognition," Duncan Mann, Hoxton's officer said.

As modern cities get fuller—70 percent of the population will live in urban areas by 2050—cameras and other technologies are taking over public spaces and collecting our data. Their purpose is to keep people safe, provide efficient services and prevent disasters and crimes.

But some are not happy with the cameras as far as their privacy(隐私) is concerned. "Very few of us have any real concept of what data smart cities are gathering," said Renate

Samson.

We begin giving away data as soon as we wake up. When we enter the transport system, we are giving away even more details about ourselves through smart cards, mobile phones or credit cards.

Nick Millman, director at a consulting firm thinks statistics are the key to the privacy concern. He used the example of Google Maps, which is to monitor the flow of traffic in Stockholm. He explained, "It is basically adding privacy controls to statistics so that you only see the data you need to know about". In this case, Google gets enough data to improve traffic but not so much that it shows individual journey patterns.

28. What is the article mainly about?

A. An introduction to collecting shoppers' data.

B. The concerns about giving away personal data.

C. The problems caused by imbalanced distribution of population.

D. An invention recording and collecting customers' information.

29. The new technology invented by Hoxton Analytics_______.

A. can gather a lot of people's personal data from their shoes

B. uses cameras fitted on the ground to collect customers' data

C has improved the accuracy of facial recognition software

D. offers a perfect solution to customers' privacy concerns

30. According to the author, cameras in modern cities_______.

A. cause a huge waste of public space

B. help reduce the size of population in urban areas

C. are likely to help improve traffic conditions

D. are to avoid crimes and disasters and provide efficient services

31. What is Renate Samson's attitude toward the rise of smart cities?

A. Worried.

B. Optimistic.

C. Confused.

D. Uninterested.

Sleep repairs the body and the mind and helps prevent disease by strengthening the immune system. However, many adults do not get eight hours of sleep each night. The average adult today gets only 6.4 hours of sleep. Only in recent years have health professionals begun to realize the seriousness of sleep deprivation in the working population. A significant number of people work at night, work long hours, or suffer from sleeplessness or jet lag.

Studies show that the brain is negatively affected by sleep deprivation because certain patterns of electrical and chemical activity that occur during sleep are interrupted and the brain cannot function normally. In one study, thirteen healthy adult subjects(实验对象) who usually had normal sleep patterns were kept awake and carefully monitored in a lab during a period of 35 hours. During the experiment, the subjects were asked to perform several tasks, such as mathematics and word problems, while undergoing scans of their brain activity. The researchers found that the temporal lobe (颞叶) of the brain, the region involved in language processing, was active during

speech tasks in rested subjects but not in subjects who lacked enough sleep. After several hours without sleep, there was no activity within this region.

Several studies show that getting fewer than six hours of sleep can damage short-term memory and reaction time—thus causing a serious risk of accident. In one study of drivers, researchers reported that sleep deprivation had the same effects as being drunk. They found that people who drove after being awake for 17 hours performed worse than those with a blood alcohol level of 0.5 percent, the legal limit for drunk driving in most western European countries. The researchers concluded that countries with drunk driving laws should consider similar restrictions against sleep-deprived driving.

32. The underlined word "deprivation" in the first paragraph is closest in meaning to_______.

A. weakness

B. loss

C. discomfort

D. pain

33. The passage mentions all of the following as causes of sleep deprivation EXCEPT______.

A. jet lag

B. long work hours

C. boring work

D. working at night

34. The purpose of the study described in Paragraph 2 was to determine_________.

A. how many hours people can survive without sleep

B. how people react when their sleep is interrupted

C the changes in brain activity that occurs during sleep

D. the effects of sleep deprivation on brain activity

35. Why does the author mention blood alcohol level in Paragraph 3?

A. To show how sleep deprivation reduces the blood alcohol level.

B. To show that sleep deprivation has the same dangerous effects as being drunk.

C. To suggest that sleep-deprived drivers are also likely to drink.

D. To argue against raising the legal limit for drunk driving.

2018成人学士学位英语考试试题 I. Reading comprehension Passage 1 Since its founding in 1948, McDonald's has grown from a family burger (汉堡包) stand to a global fast-food chain, with more than 30,000 locations in 118 countries. With 58 million daily customers worldwide, McDonald’s is now s o ubiquitous around the globe that The Economist publishes a global ranking of currencies' purchasing power based on the prices charged at the local McDonald’s, called the Big Mac Index (巨无霸指数).That’s not to say that every nation carries the same m enu i tems: choices vary widely depending on location. Some Asian locations serve fried shrimp in a Big Mac roll, while McDonald’s in India doesn’t serve beef at all, relying instead on burgers made from vegetables, rice and beans. Not everyone in the world has been happy to greet Ronald McDonald when he moves to town. Many s ee McDonald's as a symbol of American economic and cultural chauvinism (沙文主义), and European nations in particular have viewed American-style fast food as an insult to their national food. A French farmer, Jose Bove, became something of a national hero in 1999 after he and a group of people destroyed a McDonald's under construction to protest globalization and "bad food." The next year, a bomb e xploded in a French McDonald’s, killing a 27-year-old employee. (76) (76)No one claimed responsibility. But regardless of whether you like their food or their policies, McDonald’s is still widely seen as one of the true pioneers of peaceful globalization. 1. According to the passage, which of the following statements is NOT TRUE. A. McDonald's was founded in 1948. B. McDonald’s has opened its restaurants in every city of the world. C. McDonald’s has over 30,000 locations in the world now. D. McDonald’s was very small in scale in the beginning. 2. The word ubiquitous in Paragraph 2 is most likely to mean ____.
