Let These Plants Swat the Bugs for You
Some plants get so hungry they eat flies, spiders, and even small frogs. What’s more amazing is that these plants occur naturally (in special environments) in every state. In fact, they’re found on every continent except Antarctica.
You’ve probably seen a Venus’ flytrap. It’s often sold in museum gift stores, department stores, and even supermarkets. A small plant, it grows 6 to 8 inches tall in a container. At the end of its stalks(茎)are specially modified leaves that act like traps. Inside each trap is a lining of tiny trigger(触发)hairs. When an insect lands on them, the trap suddenly shut. Over the course of a week or so, the plant feeds on its catch.
The Venus’ flytrap is just one of more than 500 species of meat-eating plants, says Barry Meyers-Rice, the editor of the International Carnivorous Plant Society’s Newsletter. Note: Despite any science-fiction stories(科幻小说)you might have read, no meat-eating plant does any danger to humans.
Dr. Meyers-Rice says a plant is meat-eating, only if it does all four of the following: “attract, kill, digest, and absorb” some form of insects , including flies, butterflies, and moths. Meat-eating plants look and act like other green plants—well, most of the time.
All green plants make sugar through a process called photosynthesis(光合作用). Plants use the sugar to make food. What makes “meat-eating” plants different is their bug-catching leaves. They need insects for one reason: nitrogen(氮). Nitrogen is a nutrient that they can’t obtain any other way. Why?
Almost all green plants on our planet get nitrogen from the soil. “Meat-eating” plants can’t. They live in places where nutrients are hard or almost impossible to get from the soil because of its acidity(酸度). So they’ve come to rely on getting nitrogen from insects and small animals. In fact, nutrient-rich soil is poisonous to “meat-eating” plants. Never fertilize(施肥)them! But don’t worry, either, if they never seem to catch any insects. They can survive, but they’ll grow very slowly.

The Harp Seal is one of nature’s most beautiful and appealing (吸引人的) creatures. Many years ago it was hunted for its fur. Hunting Harp Seals is now illegal.
The seals spend the summer months migrating (迁徙) in large groups. Harp Seals close their nostrils (鼻孔) and earholes when diving in water, but have to surface frequently to breathe. Their favourite place to rest is on the top of icebergs.
The female Harp Seal gives birth in February or March and feeds her pups for 14-18 days. Baby Harp Seals begin to lose their white fur at around six to eight weeks of age. As an adult, the Harp Seal has brown skin. At birth, Harp Seals weigh 12kg but can weigh up to 130kg as adults. Harp Seals eat small fish, shrimps and krill. However, they are able to switch from one food to another depending on what they can get as food. Males have a lifespan of 29 years while females usually live for longer than 30 years.
Since the Canadian Government introduced laws to protect the seal pups from hunters, their numbers have increased to more than one million. Now every year, thousands of tourists flock to the pack ice to witness the wonderful sight of new pups born in spring.
55. What is the passage mainly about?    
A. Hunting Harp Seals is illegal.
B. Protecting Harp Seals.
C. Harp Seals.    
D. Lifespan of Harp Seals.

A. brown in colour and weighing 12kg
B. brown in colour and weighing 130kg
C. white in colour and weighing 12kg    
D. white in colour and weighing 130kg
57. According to the passage which of the following statements is TRUE?    
A. Adult Harp Seals only eat shrimp.

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。
A
A lot of management training each year for Circle K Corporation, a national chain of convenience stores. Among the topics we address in our course is the retention(保护力) of quality employees-a real challenge to managers when you consider the pay scale(标准)in the service industry. During these discussions, I ask the participants(参加者), “What has caused you to stay long enough to become a manager?” Some time back a new manager took the question and slowly, with her voice almost breaking, said, “It was a $19 baseball glove.”
Cynthia told the group that she originally took a Circle K clerk job as an interim(临时的) position while she looked for something better. On her second or third day behind the counter, she received a phone call from her nine-year-old son, Jessie. He needed a baseball glove for Little League. She explained that as a single mother, money was very tight, and her first check would have to go for paying bills. Perhaps she could buy his baseball glove with her second or third check. When Cynthia arrived for work the next morning, Patricia, the store manager, asked her to come to the small room in the back of the store that served as an office. Cynthia wondered if she had done something wrong or left some part of her job incomplete from the day before. She was concerned and confused.
Patricia handed her a box. “I overheard you talking to your son yesterday,” she said, “and I know that it is hard to explain things to kids. This is a baseball glove for Jessie because he may not understand how important he is, even though you have to pay bills before you can buy gloves. You know we can’t pay good people like you as much as we would like to; but we do care, and I want you to know you are important to us.”
The thoughtfulness, empathy and love of this convenience store manager demonstrates vividly that people remember more how much an employer cares than how much the employer pays. An important lesson for the price of a Little League baseball glove.
56.Among many of the problems in the service industry, what is talked about in this passage, is___
A.how to ensure his employees’ high pay

A.had mastered all the courses for the manager
B.had already formed good relationship with the employees
C.know the way how to deal with her employees
D.had her own personal experience
58.This passage shows us that to run a business well it is necessary for managers to let their employees know________
A.how much they can get for their job.
B.what good positions they can get later
C.they are very necessary to the business  
D.they are nice as well as useful
59.The story told in this passage tells us that employees care about____________

C.if their children could be properly taken care of
D.what position they can be offered

Recently, a survey was done among 288,000 students, which shows that today’s traditional-age college freshmen are “more materialistic and less altruistic (利他主义的)” than at any time in the 19 years of the poll (民意调查).
Not surprisingly, in these hard times, the students’ major purpose “is to be financially well off. Developing a meaningful philosophy of life is less important than ever.” It follows then that today the most popular course is not literature or history but accounting.
Interest in teaching, social service and the “altruistic” fields is at a low. On the other hand, enrollment in business programs, engineering and computer science is way up.
That’s no surprise either. A friend of mine (a sales representative for a chemical company) was making twice the salary of her college instructors in her first year on the job---even before she completed her two-year associate degree.
Though it’s true that we all need a career, it is equally true that our civilization has accumulated an incredible amount of knowledge in fields far beyond our own and that it will be better for our understanding of these other contributions—either scientific or artistic.
Similarly, it is true that, in studying the diverse wisdom of others, we learn how to think. More importantly, perhaps, education teaches us to see the connections between things, as well as to see beyond our immediate needs.
Weekly we read of unions who went on strike for higher wages, only to drive their employer out of business. No company; No job. How shortsighted in the long run!
But the most important argument for a broad education is that in studying the accumulated wisdom of the ages, we improve our moral sense. I saw a cartoon recently which shows a group of businessmen looking puzzled as they sit around a conference table; one of them is talking on the intercom (对讲机) : “Miss Baxter,” he says, “could you please send in someone who can distinguish right from wrong?”
From the long-term point of view, that’s what education really ought to be about.
51. According to the result of the survey, college students _______________.
A. take developing a meaningful philosophy of life more seriously
B. have a wide range of knowledge in many aspects
C. pay more attention to the study of literature
D. have never been so materialistic as today
52. The students’ criteria (标准) for choosing their majors today are largely based on _________.
A. their own understanding of the courses
B. the financial goals they seek in life
C. the influence of their instructors
D. the vast potential for the future educational development
53. What does the fifth paragraph imply?
A. Knowledge in other fields has nothing to do with one’s career.
B. Business management should be included in educational programs
C. The importance of a broad education should not be ignored
D. A good understanding of the civilization will make students rich.
54. The author’s attitude to the effect of studying the diverse wisdom of others is ______________.
A. positive          B. indifferent              C. doubtful           D. negative
55. The writer wrote the passage in order to indicate that ______________.
A. college students today are not a diligent generation
B. people engaged in technical jobs lead a more meaningful life
C. career seekers shouldn’t focus on immediate interests only
D. working experience outside college counts a lot to one’s future career
