Plants can’t communicate by moving or making sounds, as most animals do. Instead, plants produce volatile compounds, chemicals that easily change from a liquid to a gas. A flower’s sweet smell, for example, comes from volatile compounds that the plant produces to attract insects such as bugs and bees.
Plants can also detect volatile compounds produced by other plants. A tree under attack by hungry insects, for instance, may give off volatile compounds that let other trees know about the attack, In response, the other trees may send off chemicals to keep the bugs away- or even chemicals that attract the bugs’ natural enemies.
Now scientists have created a quick way to understand what plants are saying: a chemical sensor(传感器) called an electronic nose. The “e-nose” can tell compounds that crop plants make when they’re attacked. Scientists say the e-nose could help quickly detest whether plants are being eaten by insects. But today the only way to detect such insects is to visually inspect individual plants. This is a challenging task for managers of greenhouses, enclosed gardens that can house thousands of plants.
The research team worked with an e-nose that recognizes volatile compounds. Inside the device, 13 sensors chemically react with volatile compounds. Based on these interactions, the e-nose gives off electronic signals that the scientists analyze using computer software.
To test the nose, the team presented it with healthy leaves from cucumber, pepper and tomato plants, all common greenhouse crops. Then the scientists collected samples of air around damaged leaves from each type of crop. These plants had been damaged by insects, or by scientists who made holes in the leaves with a hole punch (打孔器).
The e-nose, it turns out, could identify healthy cucumber, pepper and tomato plants based on the volatile compounds they produce. It could also identify tomato leaves that had been damaged. But even more impressive, the device could tell which type of damage – by insects or with a hole punch – had been done to the tomato leaves.
With some fine tuning, a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs, the researchers say. A device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat, says Natalia Dudareve, a biochemist at Purdue University in West Lafayette, Ind. who studies smells of flowers and plants. Hopefully, scientists believe, the device could bring large benefits to greenhouse managers in the near future.

In ancient Egypt, the pharaoh(法老) treated the poor message runner like a prince when he arrived at the palace, if he brought good news. However, if the exhausted runner had the misfortune to bring the pharaoh unhappy news, his head was cut off.
Shades of that spirit spread over today’s conversations. Once a friend and I packed up some peanut butter and sandwiches for an outing. As we walked light-heartedly out the door, picnic basket in hand, a smiling neighbor looked up at the sky and said, “Oh boy, bad day for a picnic. The weatherman says it’s going to rain.” I wanted to strike him on the race with the peanut butter and sandwiches. Not for his stupid weather report, for his smile.
Several months ago I was racing to catch a bus. As I breathlessly put my handful of cash across the Greyhound counter, the sales agent said with a broad smile, “Oh that bus left rive minutes ago.” Dreams of head-cutting!
It’s not the news that makes someone angry. It’s the unsympathetic attitude with which it’s delivered. Everyone must give bad mews from time to time, and winning professionals do it with the proper attitude. A doctor advising a patient that she needs an operation dose it in a caring way A boss informing an employee he didn’t get the job takes on a sympathetic tone. Big winners know, when delivering any bad news, they should share the feeling of the receiver.
Unfortunately, many people are not aware of this. When you’re tired from a long flight, has a hotel clerk cheerfully said that your room isn’t ready ye? When you had your heart set on the toast beef, has your waiter merrily told you that he just served the last piece? It makes you as traveler or diner want to land your fist right on their unsympathetic faces.
Had my neighbor told me of the upcoming rainstorm with sympathy, I would have appreciated his warning. Had the Greyhound salesclerk sympathetically informed me that my bus had already left, I probably would have said, “Oh, that‘s all right. I’ll catch the next one.” Big winners, when they bear bad news, deliver bombs with the emotion the bombarded (被轰炸的) person is sure to have .

A. was mad at the sales agent.
B. was reminded of the cruel pharaoh
C. wished that the sales agent would have had dreams.
D. dreamed of cutting the sales agent’s head that night.
56. What is the main idea of the text?
A. Delivering bad news properly is important in communication.
B. Helping others sincerely is the key to business success.
C. Receiving bad news requires great courage.
D. Learning ancient traditions can be useful.
Four people in England, back in 1953, stared at photo 51. it wasn’t much –a picture showing a black X. But three of these people won the Nobel Prize for figuring out what the photo really showed—the shape of DNA. The discovery brought fame and fortune to scientists James Watson, Francis crick, and Maurice Wilkins. The fourth, the one who actually made the picture, was left out.
Her name was Rosalind Franklin. “She should have been up there,” says historian Mary Bowden. “If her photo hadn’t been there, the others couldn’t have come up with the structure.” one reason Franklin was missing was that she had died of cancer four years before the Nobel decision. But now scholar doubt that Franklin was not only robbed of her life by disease but robbed of credit by her competitions.
At Cambridge University in the 1950s, Watson and Crick tried to make models by cutting up shapes of DNA’s parts and then putting them together. In the meantime, at king’s college in London, Franklin and Wilkins shone X-rays at the molecule(分子). The rays produced patterns reflecting the shape.
But Wilkins and Franklin’s relationship was a lot rockier than the celebrated teamwork of Watson and Crick. Wilkins thought Franklin was hired to be his assistant. But the college actually employed her to take over the DNA project.
What she did was produce X-ray pictures that told Watson and Crick that one of their early models was inside out. And she was not shy about saying so. That angered Watson, who attacked her in return,” Mere inspection suggested that she would not easily bend. Clearly she had to go or be put in her place.
As Franklin’s competitors, Wilkins, Watson and Crick had much to gain by cutting her out of the little group of researchers, says historian Pnina Abir-Am. In 1962 at the Nobel Prize awarding ceremony, Wilkins thanked 13 colleagues by name before he mentioned Franklin. Watson wrote his book laughing at her. Crick wrote in 1974 that “Franklins was only two steps away from the solution.”
No, Franklin was the solution.” She contributed more than any other player to solving the structure of DNA. She must be considered a co-discoverer,” Abir-Am says. This was backed up by Aaron Klug, who worked with Franklin and later won a Nobel Prize himself. Once described as the “Dark Lady of DNA”, Franklin is finally coming into the light.
57. What is the text mainly about?
A. The disagreements among DNA researchers.
B. The unfair treatment of Franklin.
C. The process of discovering DNA.
D The race between two teams of scientists.
58. Watson was angry with Franklin because she ______.
A. took the lead in the competition
B. Kept her results from him
C. proved some of his findings wrong
D. shared her data with other scientists
59. Why is Franklin described as “Dark Lady of DNA”?
A. She developed pictures in dark labs.
B. She discovered the black X------ the shape of DNA.
C. Her name was forgotten after her death.
D. Her contribution was unknown to the public.
60. What is the writer’s attitude toward Wilkins, Watson and Crick?
第二节: Bryan、Olga、Scott、Anna 和David正在进行一项“企业家成功秘诀调查”。他们将采访几位企业家。第61-65题是他们拟定的采访话题。阅读下面刊登在Entrepreneur(《企业家》)杂志上6位企业家的成功感言（A.B.C.D.E和F），为每位采访者选定最佳采访对象，并在答题纸上将该选项标号涂黑。选项中有一项是多余选项。
61．Bryan: What comes first, the customer or the profit?
62. Olga: How important is an entrepreneur’s ambition to his/her company’s growth?
63. Scott: How does an entrepreneur make use of his/her advantages?
64. Anna: Why do successful entrepreneurs seem to enjoy their work?
65. David: What attitude should an entrepreneur have toward his/her social responsibilities?
Since I started this company in my kitchen seven years ago, I always dreamt of what it would be some day. Focusing on that goal helps me get through tough times .To get the kind of success that you want; you need to dream big .That’s the starting point. Every success story begins with big dreams. You need to have big dreams for yourself, like being somebody rich, famous or fulfilled .You need to have a clear goal of what you want to achieve.
Also, I think it’s really important that the people you’re working with are as committed to the same goal as you are, so you can support each other and keep each other energetic.
The Body Shop Inc.
In America, we have a shop in Harlem where 50 percent of the profits go into the community development, and the other 50 percent go toward the funding of a similar shop elsewhere in the United States. The pride that shop brings to the staff and local people inspired me.
What The Body Shop does successfully is use our facilities in the street and shopping centers to talk about real human issues like AIDS, recycling, human rights, and community service or to encourage people to speak out against anything they consider to be unjust. Knowing our products are symbols of social change is really encouraging.
Ben &Jerry’s Homemade Inc.
I’m energized by the people I work with. I’m very relationship-driven, which a think is different from most entrepreneurs. I’m inspired by doing things that are not normal and that most people think don’t fit into the business world or don’t make any sense.
In business, you are judged by the company you keep—from your management team, board of directors, and strategic partners. Maybe the lady you met in a trade association meeting can help you secure funding, or the gentleman at a conference can provide you with management advice.
Lettuce Entertain You Enterprises
A number of years ago, I was interviewed by someone who was writing a book on enterprises. He asked me. ”What’s the opposite of work?” I answered. ”Lazy” He started laughing and said, ” Believe it or not, a lot of entrepreneurs say the same thing.”
The average person thinks the opposite of work is play, but to an entrepreneur, work is play. I think it all adds up to having fun. it’s fun to create; it’s fun to entertain, and it’s fun to make people happy with our service. When it stops being fun, I’ll stop doing it.
Make-Up Art Cosmetics (M.A.C)
One of the nicest things anyone ever said to me was, “I hate makeup, but I love M.A.C.” That’s what moves me on. Even people who don’t wear makeup can appreciate our company, what it stands for, its values, and the way we do business.
We work from an inverted pyramid, where the customers are always at the top. Our customers inspire me and keep me going. They and our staff, not money, make me enthusiastic. If I had stayed in this business just for the money, I would have closed down years ago.
Kenneth Cole Productions Inc.
You can’t be everything to everybody. Each of us has our own strengths and weaknesses. To be effective, you need to identify your strengths and concentrate on them, you’ll become more successful if you are able to channel your efforts to areas that you do best. In business, for example, if you know you are good at marketing, then give it full play. Seek help or assistance in areas that you may be poor at, such as accounting or bookkeeping. To turn your weakness into strength, consider taking hands-on learning or training.
It was very nice to get your invitation to spend ∧ weekend with you. Luckily I was
completely free then, so I’ll to \ say “yes”. I’ll arrive in Bristol at around 8p.m. in Friday evening.
One rainy day while I was walking home with one of my friend, a truck came to a stop besides us. The driver put the window down and offered us a umbrella because he found we were wet through. I stood there and couldn’t believe in that a complete stranger is so thoughtful. The man insisted, so I grateful accepted the offer, thanked him and watched the truck disappear down the road. This man might need the umbrella himself, and he preferred to give it to everyone else. It was a lesson to us that it was possible give without expect anything in return.

Student Volunteers Brought Sunshine to the Elderly
On May Day, Li Yue and Zhang Hua, students from Class Three, Grade Two, went to Sunshine Nursing Home and did some voluntary work. Upon their arrival, Li Yue and Zhang Hua were warmly welcomed, and respectfully, they presented the elderly with flowers and fruits. Then, they started working at once, cleaning the windows and sweeping the floor. Everything done, they sat in the yard chatting with the elderly people.
When it was time for the volunteers to leave, the elderly people thanked them for their kindness. They said it was such a beautiful day that they would remember it forever.
Li Yue and Zhang Hua were very happy. What they did has brought joy to others and enriched their own lives.
