　　Besides this question of the time given to pronunciation，there are two other requirements for the teacher：the first，knowledge；the second，technique．

　　It is important that the teacher should be in possession of the necessary information．This can generally be go form books．It is possible to get from books some idea of the speech；and of what we call general phonetic rules．It is also possible in this way to get a clear mental picture of the relationship between the sounds of different languages，between the speech habits of English people and those，of your students．Unless the teacher has such a picture，any explanations he makes on his students'pronunciation are unlikely to be of much use，and lesson time spent on Pronunciation may well be wasted．

　　But it does not follow that you can teach pronunciation successfully as soon as you have read the necessary books．It depends，after that，what use you make of your knowledge；and this is a matter of technique．

　　Now the first and most important part of a language teacher's technique is his own performance，his ability to show off the spoken language，in every detail of sound as well as in fluent speaking，so that the student's ability for imitation is given the fullest space and encouragement．The teacher，then，should be as perfect a model in this field as he can make himself．And to make his own performance better，however satisfactory this may be，the modern teacher has in his hand recordings and a radio，to supply the real voices of native speakers，or，if the teacher happens to be a native speaker himself，or speaks just like one，then to change the method of presenting the language material．

　　However，the process of showing pronunciation，whether by personal ex-ample or with the help of machines，is only the beginning of teaching pronunciation．The technique of teaching each sound also needs to be considered．

　  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________.
