E. Need for Clean Water
F. Ways of Stopping Respiration
小题1: __________
While everybody enjoys fresh cut flowers around his house, few people know how to keep them for as long as possible. This may be done by keeping in mind a few simple facts. The key to keeping fresh cut flowers for a week or more without floral preservatives (which contain biocides that kill bacteria and fungus) is to keep the water fresh and the stems free of air pockets so they can continue to draw up water.
小题2:__________
An important thing to remember about cut flowers is that they are sensitive to temperature. For example, studies have shown that cut carnations(康乃馨) retain their freshness eight times longer when kept at 12℃ than when kept at 26℃. Keeping freshly harvested flowers at the right temperatures is probably the most important aspect of flower care.
小题3:__________
Flowers are not intended by nature to live very long. Their biological purpose is simply to attract birds or insects, such as bees, for pollination (授粉). After that, they quickly dry up and die. The process by which flowers consume oxygen and produce carbon dioxide, called respiration (呼吸), generates the energy the flower needs to give the flower its shape and color. The making of seeds also depends on this energy. While all living things respire, flowers have a high level of respiration. A result of all this respiration is heat, and for flowers the level of heat relative to the mass of the flower is very high. Respiration also brings about the eventual death of the flower. Thus the greater the level of respiration, the sooner the flower dies.
小题4: __________
How, then, to control the rate at which flowers die? By controlling respiration. How is respiration controlled? By controlling temperature. We know that respiration produces heat, but the reverse is also true. Thus by maintaining low temperatures, respiration is reduced and the cut flower will age more slowly.
小题5: __________
Another vital factor in keeping cut flowers is the quality of the water in which they are placed. Flowers find it difficult to “drink” water that is dirty or otherwise polluted. Even when water looks and smells clean, it almost certainly contains harmful substances that can endanger the flowers. To rid the water of these unwanted substances, household chlorine bleach (含氯漂白剂) can be used in small quantities. It is recommended that 15 drops of chlorine bleach (at 4% solution) be added to each liter of water. The water and solution should also be replaced each day.

小题1:Preparation is a big part of the interview process. You will, or you should, spend more time getting ready for the interview than you will at the interview itself. This preparation includes getting to know more about the company and the position you are applying for, and preparing yourself to explain how your valuable qualities make you the best person for the position. And of course, there is the time it takes to make yourself presentable. Job interview can be a stressful situation for many people. The best way to help relieve this stress is to hold a positive attitude and be well prepared. Consider the following tips as you prepare for your interview.
小题2:Think of the answers you want to give. Although you will never completely know in advance every question they will ask you, there are questions that get asked in almost every interview. Learn what they are and try to predict what the others might be. Interview questions are usually sourced from the job posting. If they are looking for a particular skill set, make sure you can explain how you will meet that expectation.
小题3:Do your best to get information about the company before the interview. Do some research, such as using their website, scanning through annual reports if they publish one, being familiar with the project they are now working on. This will help you to present your answers in the context of what their core business is about.
小题4:Most job postings have a list of core duties or responsibilities as well as what qualifications are required. Study these well and prepare your answers accordingly. Think about what education and training you have had and what work experiences you have done that makes you the ideal person for the position. Be thorough in your self-assessment, think broadly about all you have learned and experienced. You may surprise yourself with what skills you have acquired previously.
小题5:In most cases, the interviewer will have your resume already, but it never hurts to have some back-up copies just in case. And be sure they are the most current and relevant resume for the position.
