Bum rate is the speed at which a startup business consumes money. My rate would be $ 50,000 a month when my new media company started. So, I began looking around for individuals who would be my first investors. “Angel money” it was called. But when I reviewed my list of acquaintances to find those who might be able to help, I found the number got small.

　　With no other choices, I began meeting with the venture-capital companies. But I was warned they took a huge share of your company for the money they put in. And if you struggled, they could drop you cold.

　　As I was searching for “angel money”, I started to build a team who trusted me even though I didn't have money for paychecks yet.

　　Bill Becker was an expert in computer programming and image processing at a very famous Media Lab at M. I.T. With his arrival, my company suddenly had a major technology “guy” in-house.

　　Katherine Henderson, a filmmaker and a former real-estate dealer, joined us as our director of market research. Steve White came on as operating officer. He had worked for the developer of a home-finance software, Quicken. We grabbed him.

　　We had some really good people, but we still didn't have enough money. One night, my neighbor, Louise Johnson, came for a visit. She and I were only nodding acquaintances, but her boys and ours were constant companions. She ran a very good business at the time.

　　Louise was brilliant and missed nothing. She had been watching my progress closely. She knew I was dying for money and I had prospects but could offer no guarantees of success.

　　She told me that her attorney had talked to mine and the terms had been agreed upon. She handed me an envelope. Inside was a check for $ 500,000.

　　I almost fell down. I heard her voice as if from heaven.

　　“I have confidence in your plan,” she said. “You' 11 do well. You're going to work hard for it, but it' s satisfying when you build your own company.”

　　Who would have thought I'd find an angel so close to home? There were no words sufficient for the moment. We just said good night. She left and I just stood there, completely humbled and completely committed.

　  Animals can move from place to place, but plants cannot. When an animal is under attack, it can run away or fight back. Plants certainly cannot run away, and they lack teeth and claws. But plants can defend (保护) themselves by using both physical and chemical means.
　　Some plants have their own ways to keep animals away. For example, the leaves of the holly plant have sharp spines (刺) that discourage grass-eating animals. Holly leaves on lower branches have more spines than leaves on upper branches. This is because the lower leaves are easier for most animals to reach.
　　Some plants, such as the oak tree, have thick and hard leaves that are difficult for animals to eat. Some grasses may contain a sandy material; eating such grasses wears down the animal's teeth.
　　Many plants also have chemical defenses. Some plants produce chemicals that taste bitter or cause an unpleasant reaction. Some plants may fight against an attack by increasing the production of these chemicals. When a caterpillar (毛虫) bites a tobacco leaf, the leaf produces a chemical messenger. This messenger sends to the roots the information to produce more nicotine. The higher levels of nicotine discourage the caterpillar.
Many plants depend on both physical and chemical defenses. A certain plant in China, for instance, has prickly (多刺的) leaves, and each prickle contains poisonous venom (毒液) A single experience with this kind of plant will teach an animal to stay away from it in the future. 
【小题1】To defend themselves, oak trees use________.
