3.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.

  • 第3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.
    Pruning should be done to__________.

    A.make the tree grow taller
    B.improve the shape of the tree
    C.get rid of the small branches
    D.make the small branches thicker

    答案：B
    解析：
    由第二段第一句“pruning may be done to make sure that trees have a desired shape or size”可知答案选B，即修剪有时是为了树木有个好外形。

    Trees become unhealthy if the gardener__________.

    A.allows too many branches to grow in the middle
    B.does not protect them from wind
    C.forces them to grow too quickly
    D.damages some of the small side branches

    答案：A
    解析：
    由第二段最后一句“the health of a tree may be encouraged by removing branches that are blocking up the centre”可知，剪去阻塞树木中央空间的枝条可使树木健康生长，那么相反，保留这些枝条则会导致树木长得不健康，因此答案为A。
