Trees should only be pruned when there is a good and clear reason for doing so and , fortunately,the number of such reasons is small. Pruning involves the cutting away of obergrown and unwanted branches, and the inexperienced gardener can be encouraged by the thought that more damage results from doing it unnecessarily than from leaving the tree to grow in its own way.
First, pruning may be done to make sure that trees have a desired shape or size. The object may be to get a tree of the right height, and at the same time to help the growth of small side branches which will thicken its appearance or give it a special shape. Secondly, pruning may be done to make the tree healthier. You may cut diseaed or dead wood, or branches that are rubbing against each other and thus cause wounds. The health of a tree may be encouraged by removing branches that are blocking up the centre and so preventing the free movement of air.
One result of pruning is that an open wound is left on the tree and this provides an easy entry for disease, but itis a wound that will heal. Often there is a race between the healing and the desease as to whether the tree will live or die, so that there is a period when the tree is at risk. It should be the aim of every gardener to reduce which has been pruned smooth and clean, for healing will be slowed down by roughness. You should allow the cut surface to dry for a few hurs and then paint it with one of the substances available from garden shops produced especially for this purpose. Pruning is usually without interference from the leaves and also it is very unlikely that the cuts yu make will bleed. If this does happen,it is, of course,impossible to paint them properly.

拓展阅读：英语四级仔细阅读答题窍门
1、体现中心思想的选项是答案
文中的细节、例子、引语都是为了说明文章主旨、段落主旨，所以考查细节的题目，虽然不是主旨题，但能体现中心思想或段落主旨的选项是答案的可能性要远远大于其他选项。
2、看似合理的选项不是答案，看似不合理的选项是答案
四个选项中若有一个对问题而言、根据常识看似不合理，而其他几项根据常识都可合理地作为问题的答案，此时若没看懂文中意思，就可以大胆猜测可能这个看似不合理的选项是答案。作为答案的选项看起来不合理的原因可能是其中某个词不是常用意义，若根据其通常意义理解则该选项看起来非常不合理，也可能是此问题有一些特定的.理由。无论是哪种情况，都有助于使试题具有难度。所以根据命题的难度原则及实践经验可得出如下猜题技巧：看似不合理的选项是答案，看似合理的选项不是答案。
3、照抄原文的不是答案，和原文作同义替换的选项是答案
在设计题目时，为了迷惑考生，命题者一般都会将原文中的内容换个说法作为正确答案的选项，而将某些与题干问题不符的原文原话设计为干扰项，或将原文的某些句子作细微的改变引诱考生上当。
4、含义肯定的选项不是答案，含义不肯定的选项是答案
选项中的might等词语可以表达一种委婉、中庸、不肯定的语气，为表达的观点留有余地，而含义肯定的词语则使得句意有些绝对、没有余地。凡事都不能太绝对，所以选项“含义肯定的不是答案，含义不肯定的是答案”。含义不肯定的标志有：can， could， probably， may， might， be likely to， most， more or less， relatively等。含有这些词的备选项是答案的可能性较大。
