Talking plants might sound like characters in a fairy tale. But recent scientific studies have shown that plants communicate with each other and with other living things in a surprising number of ways. To understand them, scientists say, we just have to learn their language. Farmers are especially interested in what plants have to say.
“Plants are able to communicate with all sorts of organisms (有机体). They can communicate with giant bacteria, with other plants and with insects. They do this chemically,” said Cahill, an Ecology Professor of the University of Alberta in Canada.
Plant scientists are just beginning to understand this chemical “ language”. Cahill says studies have shown, for example, that plants can evaluate conditions in their immediate environment and take appropriate actions. Plants have an ability, for example, to signal pain or discomfort caused by anything from temperature extremes to an insect attack. Jack Schultz, a professor of chemical ecology at the University of Missouri, says when a plant senses that it’s being eaten, it cannot walk away from trouble; on the contrary, it will release a chemical vapor that alerts other plants nearby.
“Their language is a chemical language, and it involves chemicals that move through the air that are easy to be changeable, and most of all are smells that we are familiar with,” Schultz explained.
“All plants responded to the attack by changing their chemistry to defend themselves,” Schultz recalled. “But we were quite surprised to find that nearby plants also changed their chemistry to defend themselves, even though they were not part of the experiment.”
Studies have also shown that plants under attack release pleasant chemicals. Those chemicals attract friendly insects that attack the pests eating the plant.
In the end, plants’ ability to communicate their needs---and our ability to understand them--- could help farmers reduce the use of poisonous chemicals, cut operating costs and limit damage to the environment.

Job interviews never seem easy.To get a job,you may have more interviews than you can count.To succeed in an interview，you should pay attention to the following common mistake.
Lack of proper preparations.Failure to gather information on the company and the job before the interview makes a very poor impression on interviews;it suggests that you are not really that interested in the position.
Inappropriate personal appearance.Consider the nature of the position and dress accordingly.When in doubt,dressing somewhat more formally than you think would be expected for the job.Be conservative and pay attention to details,such as shiny shoes,neat hair,etc.First impressions are very important.
Poor non-verbal communication.In addition to what you are saying,your non-verbal behavior is very important in an interview.Are you making eye contact?Are you listening attentively when the interviewer is speaking?Are you giving a firm handshake by the interviews?Are you nervous during the interview？Practice with a friend or in front of a mirror to assess these factors.
Poor attitude.Self-centered behavior（.i.e.a”what’s in it for me”attitude）is very poorly received by interviewers.Ask yourself what you can contribute to the company?What skills and
experience would you bring to the job？
Failure to ask questions.Employers will assess your interest in the company and the position you ask.Proper research before the interview will help ensure that the questions you ask are intelligent ones.
Being disorganized.Make sure you arrive at the company a few minutes early so that you have time to get calm and check your appearance.Arriving late is simply unacceptable，so plan for the unexpected.Always bring an extra copy of your resume and reference to an interview.
Over-or under-answering questions.For most interview questions a “Yes”or “No”answer is not appropriate.Positive more details for an employer and cite examples from personal experience wherever possible.Do not,however,talk endlessly and feel that you have to keep speaking if there’s silence.When you have said what you want to say ,stop talking.If you do not understand a Question,.seek clear explanation before responding.
Failure to send a thank-you note or card following the interview.Take the time to send the thank-you card,which can make an important impact on an employer.Not only does it show your sincere interest in the position,but it also helps make you different from other interview candidates.
