蔬菜和水果长时间储藏、保鲜所需要的条件应为（　　）

A．低温、干燥、低氧

B．低温、湿度适中、低氧

C．高温、干燥、高氧

D．高温．湿度适中、高氧

答案

要延长水果的储藏时间，除要防止其受菌类污染外，还需降低其呼吸作用．应该说低温、干燥和低氧条件都有利于降低呼吸作用，同时，低温和干燥还有利于抑制菌类的生存和繁殖．但题目不仅仅是要求延长储藏时间，而且对保鲜也提出了要求．含水量是体现水果是否新鲜的重要指标，失去水分的水果将不再新鲜，所以不可作干燥处理．

故选：B

James Murray Wells founded Glasses Direct, which is now the biggest online seller of eyeglasses in the world. It sells a pair of frames every few minutes and employs 70 people in its two offices.
This English entrepreneur was still in college when he saw a great business opportunity. He saw that there was no UK online shop selling eyeglasses. He used his college loan money to start just such a business and it was successful enough to earn over $1 million during its first year in operation.
Richie Stachowski, 11, of Moraga, Calif., went diving with his dad during a vacation in Hawaii. Richie was disappointed he could not talk underwater about the many colorful and amazing things he saw.
When Richie got home, he started work on the equipment that would allow him to talk underwater. His invention — the Water Talkies — is basically a phone that allows sound wave to travel about 15 feet underwater. Water Talkies are now offered at toy stores around the country.

Fraser Doherty is an example of a young man with a more old-fashioned approach to business. At the age of 14, Fraser Doherty began making jams from his grandmother’s recipes (制作法) and selling them door-to-door in Edinburgh, Scotland. Developing the recipes and coming up with a name for his product, Doherty quit school at age 16 to work on Super jam full time. Now Super jam has an estimated worth of over $2 million based on current sales of $1 million annually.
Richard is an example of developing and using his skills to earn money. At the age of 15 he learned leather craft at a summer camp. He then made small items he could sell at the only shop in his village.
Because he was determined to produce the highest-quality work, his fame and his profit grew. Soon Richard could buy larger quantities of leather, which he made into handbags and purses. These he sold in a larger shop in the neighboring village.

F
Dorothy started her business at the age of 14, selling stick-insect eggs by mail order. Less than 20 years later, she is Great Britain’s biggest breeder (繁殖者) of stick insects. Because she had experience with insects and knew she wanted to make a career in the insect business, Dorothy studied applied biology at a university, designing the right kind of insect houses and researching proper feeding facilities for her insects. This greatly increased her ability to supply the whole package to her customers.
Ben’s family helped him turn an after-school job — cleaning swimming pools and mowing lawns — into a successful and valuable service. Because of the skills he developed through hard work, he landed a position with a large company, which paid his college fees, provided him training in a career and guaranteed him a job after graduation.
The company was not looking for a high-powered businessman; it wanted someone who had learned financial knowledge and the value of customer satisfaction — all very important entrepreneurial skills.
