Because plants cannot move or talk, most people believe that they have no feelings and that they cannot receive signals from outside. However, this may not be completely true.
People who studied plants have found out that plants carry a small electrical charge (电荷). It is possible to measure this charge with a small piece of equipment called “galvanometer”. The galvanometer is placed on a leaf off the plant, and it records any changes in the electrical field of the leaf. Humans have a similar field which can change when we are shocked or frightened.
A man called Backster used a galvanometer for his studies of plants and was very surprised at his results. He found that if he had two or more plants in a room and he began to destroy one of them - perhaps by pulling off its leaves or by pulling it out of its pot - then the galvanometer on the leaves of the other plants showed a change in the electrical field. It seemed as if the plants were signalling a feeling of shock. This happened not only when Backster started to destroy plants, but also when he destroyed other living things such as insects (昆虫).
Backster said that the plants also knew if someone had destroyed a living thing some distance away, because they signalled when a man who had just cut down a tree entered the room.
Another scientist, named Sauvin, achieved similar results to Backster’s. He kept galvanometers fixed to his plants all the time and checked regularly to see what the plants were doing. If he was out of the office, he telephoned to find out about the signals the plants were sending. In this way, he found that the plants were sending out signals at the exact times when he felt strong pleasure or pain. In fact, Sauvin could cause a change in the electrical field of his plants over a distance of a few miles simply by thinking about them.

C
I believe that animals possess greater intelligence than most people think. But plants? I've never considered the possibility of plant intelligence. The idea seems absurd.
Yet I've had friends argue that plant intelligence might exist. "What are the differences between plants and animals?" they ask, and then they argue about certain species that seem to share the intelligence of both plants and animals.
New research suggests that plants communicate via "networks". Plant communication is not idea, and cannot indicate that its is a kind of intelligence, but it is still interesting.
Recent research from Vidi researcher Josef Stuefer at the Radboud University Nijmegen shows that plants have their own chat systems that they can use to warn each other. Therefore plants are not boring and passive organisms that just stand there waiting to be cut down or eaten up. Many plants form internal communication networks and are able to exchange information networks and are able to exchange information efficiently.
Many herbal plants such as strawberries and clovers (三叶草)naturally form networks.
Individual plants remain connected with each other for a certain period of time by means of runners (plant stems that grow along the ground and put down roots to form new plants). These connections enable the plants to share information with each other via internal channels. They are therefore very similar to computer networks. But what do plants chat to each other about?
Recently Stuefer and his colleagues were the first to prove that clover plants warn each other via the network links if danger is nearby . If one of the plants is attacked by caterpillars (毛虫),the other members of the network are warned via an internal signal. Once warned the intact (完好无损的)plants strengthen their chemical and mechanical (机体的)resistance so that they are less attractive to advancing caterpillars. Thanks to this early warning system, the plants can stay one step ahead of their attackers. The research has shown that this significantly limits the damage to the plants.
Again, I don't believe this reflects intelligence, but it's is certainly fascinating.
66.The author thinks that the plant communication .
A.is absolutely a new idea
B.is a sign of plant intelligence
C.is related to animal communication
D.is interesting and fascinating
67.Clover plants warn each other when danger is nearby by .
A.making sounds
B.releasing chemicals
C.strengthening mechanical resistance
D.sending internal signals
68.Which of the following statements about the research is NOT true?
A.Most plants have no chat system and are passive organisms.
B.Individual plants can also remain connected with each other.
C.The communication between clover plants can protect them from damage.
D.The research is the first to show how clover plants warn each other.
69.The author's attitude towards plant intelligence is
A. unconcerned B. doubtful C. positive D. hopeful
70" What's the best title for the passage?
A.Does Plant Communication Really Exist?
B.Some Discoveries About Clover Plant
C.Does Plant Communication Imply Intelligence?

Although most people believe that owning a business or working on an idea means you are an entrepreneur (企业家), the reality is that entrepreneurship is so much more than just these two things. It is about the ability to innovate (创新) by helping society progress. For those who aspire to become real entrepreneurs, the path to turn your thought into entrepreneurship is one that requires you to know yourself.
Recognize what skills you are good at. Everybody wants money. But many fail to realize that money is the extension ( 延伸) of your skills, so the most important aspect of learning to make money starts by knowing what skills you have. Make a list of your skills and you should see where your strengths lie. The goal with this exercise is to recognize what skills you are good at naturally. Make good use of them until you finally change more of your skills into usable abilities for your business.
Make use of your confidence to create belief. Confidence is a result of repeating one thing. The more you practice doing something, the more confident you become in the process needed to see it to the end . Starting a business requires confidence, so most people who have zero confidence in the process fail to get started because it is an unknown area. You have to believe in the idea, the process and the ability within yourself to bring your business project to life. Without confidence, belief doesn't exist; without belief, the chances of giving up are high.
Allow your love to become enthusiasm. The last ingredient outside of your skills and confidence is the ability to focus on ideas that you feel enthusiastic about. Having passion will push you to struggle for something you love and turn that longing into action. The goal is to identify topics of interest so that you can start showing some aspects of passion as you start your project. The closer a project is to your heart, the less pessimistic you will become when results don't go your way.

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.
1.We learn from the text that plants communicate with each other by______.
A. making some sounds B. waving their leaves
C. producing some chemicals D. sending out electronic signals
2.What did the scientists do to find out if the e-nose worked?
A. They presented it with all common crops..
B. They fixed 13 sensors inside the device.
C. They collected different damaged leaves.
D. They made tests on damaged and healthy leaves.
3.According to the writer, the most amazing thing about the e –nose is that it can ______.
A. pick out ripe fruits
B. spot the insects quickly
C. distinguish different damages to the leaves
D. recognize unhealthy tomato leaves
4.We can infer from the last paragraph that the e-nose_____.
A. is unable to tell the smell of flowers
