Passage ThreeTrees should only be pruned (修剪) when there is a good reason for doing so. Many gardeners believe 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. The object may be to get a tree of the right height, and 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 causing wounds. A tree may grow healthier by removing the branches that are locking 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 (进入) for diseases, but it is a wound that will heal. Often there is a race between the healing and the disease as to whether the tree will live or die. Pruning is usually clone in winter, for then you can see the shape of the tree clearly without the interference from the leaves.41. According to the article, which of the following statement is NOT true?A. Pruning is necessary when there are unwanted branches.B. Damage is done to a tree if it is left to grow in its own way.C. Diseased or dead branches should be cut away if they are found to rub against each other.D. Growing side branches often prevent air from moving freely.
考题
Which of the following usually causes a tree to grow unhealthy?A. Giving a tree a special shape and a definite height.B. Removing small side branches and making a tree look less thick.C. Allowing too many branches to grow in the middle.D. Having a tree surrounded by many other trees.
考题
The writer suggests that pruning should be done in winter because______.A. the cut surface can heal more quicklyB. open wounds on the tree run the less risk of getting diseasedC. a gardener can do pruning more easilyD. the leaves can interfere
考题
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 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 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 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 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 it is a wound that will heal. 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 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 hurts 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 you make will bleed. If this does happen, it is, of course, impossible to paint them properly.
Why is a special substance painted on the tree?A.To make a wound smooth.
B.To prevent disease entering a wound.
C.To cover a rough surface.
D.To help a wound to dry.
