Trees should only be pruned (修剪) when there is a good and clear reason for doing so and , he number of such reasons is small . Pruning involves the cutting away of overgrown 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 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 out diseased 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 center 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 it is a wound that will heal (愈合) . Often there is a race between the healing and the disease 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 that risk of death as far as possible . It is important to make the area , which has been pruned , smooth and clan , for healing will be slowed down by roughness . You should allow the cut surface to dry for a few hours and then paint it with one of the materials available from garden shops produced especially for this purpose . Pruning is usually done in winter , for then you can see the shape of the tree clearly without interference (妨碍) from the leaves and also it is very unlikely that the cuts you make will bleed . If this does happen , it is , of course , impossible to paint them properly .

Protests (抗议) at the use of animals in research have taken on a new and fearful character in Britain with the attempted murder of two British scientists by the terrorist (恐怖分子的) technique of the pre-planted car–bomb .
The research community (社团) will rightly be alarmed at these developments which have two aims :to draw public attention and to frighten people working in research with animals . The scientists insist that everything should be done to identify those responsible for the crimes and to put them on trial . The Defense Research Society has taken the practical step of offering a reward of £10，000 for information leading to those responsible , but past experience is not encouraging . People are unlikely to be attracted by such offers . The professional police will similarly be challenged by the problem of finding a needle in a haystack .
That is why the intellectual (知识分子) community in Britain and elsewhere must act more strongly in its own defense . There are several steps that can be taken , of which the chief one is to demand of all the organizations that exist with the declared aims of defending the interests of animals that they should declare clearly where they stand on violence towards people . And it will not be enough for the chairman and chairwoman of these organizations to make placatory (安抚的) statements on behalf of all their members . These people should also promise that it will be a test of continuing membership in their organizations that members and would-be members should declare that they will take no part in acts of violence against human beings .
67．The words “these developments” (Linel , Para .2 ) most probably refer to .
A．the use of animals in research
B．the acts of violence against scientists
C．the techniques of planting bombs in cars
D．setting up of new animal protection organizations
68．Which of the following is true according to the passage ?
A．The police gave up their efforts to find the criminals .
B．The terrorists escaped with the help of their organization .
C．The attempted murder caused great anxiety among British scientists .
D．People supported the animal protectors in spite of their extremist acts .
69．The author’s purpose in writing this article is to demand that animal-protecting organizations .
A．give up the use of violence
B．declare their aims clearly
C．continue the dialogue with the scientific community
D．help to fid those responsible for the attempted murder
70．In the author’s opinion , .
A．animal-protecting organizations should be declared illegal
B．the scientists should take effective measures to protect themselves
C．since people can lie , the problem about eh rights of scientists can’t be solved
D．animal-protecting organizations should help the police to fight against the acts of violence
against scientists
