More than 10 years ago, it was difficult to buy a tasty pineapple. The fruits that made it to the UK were green on the outside and, more often than not, hard with an unpleasant taste within. Then in 1996, the Del Monte Gold pineapple produced in Hawaii first hit our shelves.
The new type of pineapple looked more yellowy-gold than green. It was slightly softer on the outside and had a lot of juice inside. But the most important thing about this new type of pineapple was that it was twice as sweet as the hit-and-miss pineapples we had known. In no time, the Del Monte Gold took the market by storm, rapidly becoming the world’s best-selling pineapple variety, and delivering natural levels of sweetness in the mouth, up until then only found in tinned pineapple.
In nutrition(营养) it was all good news too. This nice-tasting pineapple contained four times more vitamin C(维生素C) than the old green variety. Nutritionists said that it was not only full of vitamins, but also good against some diseases. People were understandably eager to be able to buy this wonderful fruit. The new type of pineapple was selling fast, and the Del Monte Gold pineapple rapidly became a fixture in the shopping basket of the healthy eater.
Seeing the growing market for its winning pineapple, Del Monte tried to keep the market to itself. But other fruit companies developed similar pineapples. Del Monte turned to law for help, but failed. Those companies argued successfully that Del Monte’s attempts to keep the golden pineapple for itself were just a way to knock them out of the market.
小题1:We learn from the text that the new type of pineapple is ______.

A．green outside and sweet inside	B．good-looking outside and soft inside

　　Fear can be fun. Many young people queue up to ride very fast and scary roller coasters, screaming but enjoying themselves. Other people like to read “goose bumps (鸡皮疙瘩)” books or watch horror movies at night, scared to death but feeling excited. Why do people like being scared?
　　Fear is an ancient way of surviving. Being scared makes animals, including humans escape from danger and save themselves. It is because of fear that we have lived through millions of years of evolution. Those who lacked a strong fear response were more likely to be killed, leaving the more fearful and careful to pass their genes onto the next generation.
　　How do scientists explain why shaking over such scary things is fun? “Some kids will go to a scary movie and love it and laugh over it, others will feel anxious and hide their faces and some won’t even set foot in the cinema,” said Ned Kalin, a US scientist. “Which kind of person you are depends partly on experiences you’ve had and partly on your genes.”
　　What happens in the brain when something frightens you? Nerves that begin at the eyes and ears lead to a part of the brain called the amygdale. When you suddenly see a snake, for example, the amygdale makes you freeze, sweat, have a quickened heartbeat, or run very fast. However, seeing the snake also uses another part of the brain, the cortex. It analyzes the situation, and if it finds that the snake is only made of rubber it tells your heart and the rest of your body to calm down. Think of the amygdale as the engine and the cortex as the brake.
　　Back to the first question: Why do some people like to make themselves scared? “One reason is that we can play games with fear, find ways to reduce the scariness by looking away or thinking of something else,” Kalin said. “To believe we have control over a situation gives us a feeling of power.” “Scary movies or novels are good practice to prepare young people for the real thing. Thrills such as roller coaster rides also go to the brain’s pleasure centre.”
　　And there might be some evolutionary advantage to being able to adjust this system that is there to protect people.
　　72. How many questions are answered in the passage?
　　A. 2. 　　　B. 3. 　　　C. 4.　　　 D. 5.
　　73. Some people like to be scared because______.
　　A. they are afraid that the fear genes will be passed onto their children
　　B. it’s a good practice to get prepared for the real frightening situation
　　C. it can help them show their own personalities
　　D. they will feel powerful after getting rid of fear
　　74. Which of the following is true about the people who are not easily scared?
　　A. Their cortex is better at analyzing the situations.
　　B. They are more likely to suffer from potential danger.
　　C. They are born unaffected by anything horrible.
　　D. They lack a strong response towards threat.
　　75. What is the best title of the passage?
　　A. Ready to scream? 　　　　B. How to be scared?
　　C. Willing to shake?　　　　D. Why to be scared?

Sharing Beauty
It was in October. I was aimlessly wandering down the street, heading into a most gloriously beautiful sunset. I had an urge to speak to someone on the street to share that beauty, but it seemed everyone was in a hurry.
I took the next-best action. Quickly I ducked into a department store and asked the lady behind the counter if she could come outside for just a minute. She looked at me as though I were from some other planet. She hesitated, and then seemingly against her better judgment, she moved toward the door.
When she got outside I said to her, “Just look at that sunset! Nobody out here was looking at it and I just had to share it with someone.”
For a few seconds we just looked. Then I said, “God is in his heaven and all is right with the world.” I thanked her for coming out to see it; she went back inside and I left. It felt good to share the beauty.
Four years later my situation changed greatly. I came to the end of a twenty-year marriage. I was alone and on my own for the first time in my life. I lived in a trailer park which, at the time, I considered a real come-down, and I had to do my wash in the community laundry room.
One day, while my clothes were going around, I picked up a magazine and read an article about a woman who had been in similar circumstances. She had come to the end of a marriage, moved to a strange community, and the only job she could find was one she disliked: clothing sales in a department store.
Then something that happened to her changed everything. She said a woman came into her department store and asked her to step outside to look at a sunset. The stranger had said, “God is in his heaven and all is right with the world,” and she had realized the truth in that statement. From that moment on, she turned her life around.
小题1:The author asked the woman to go outside to ______.

小题2:Four years later, the author ______.

A．found her dream job

B．put an end to her marriage

C．worked in a laundry room

D．lived in the same community

小题3:After reading the article in the magazine, the author was probably______.

A．A New Discovery	B．Zinc and Health
C．How Zinc Works	D．Add Zinc to Your Food
