Trees should only be pruned(修剪)when there is a good and clear reason for doing so and，fortunately, the number of such reasons is small.Pruning involves 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 trees to grow in their own ways. 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 out diseased or dead wood, or branches that are rubbing against each other and thus causing wounds.The health of a tree may be encouraged 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 for diseases，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, or that there is a period when the tree is at risk.It should be the aim of every gardener to reduce the risk as far as possible.It is essential to make the area 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 hours and then paint it with one of the substances 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 the interference(妨碍)from the leaves and it is, too, very unlikely that the cuts you make will bleed.If this does happen, it is, of course, impossible to paint them properly. Why should pruning be done?
A.Because it can make trees grow taller.
B.Because it can improve the shape of the trees.
C.Because it can get rid of the small ranches.
D.Because it can make the small branches thicker.
Trees become unhealthy if the gardener_________.
A.to helps a wound to dry
B.to covers a rough surface
C.damages some of the small side branches
D.allows too many branches to grow in the middle
Why is a special material painted on the tree?
A.Because it can help a wound to dry.
B.Because it can cover a rough surface.
C.Because it can make a wound smooth.
D.Because it can prevent disease entering a wound.

The establishment of the Third Reich influenced events in American history by starting a chain of events which culminated in war between Germany and the United States.The complete destruction of democracy, the persecution of Jews, the war on religion, the cruelty and barbarism of the Nazis, and especially the plans of Germany and her allies, Italy and Japan, for world conquest caused great indignation in this country and brought on fear of another world war、While speaking out against Hitler^s atrocities, the American people generally favored isolationist policies and neutrality.The Neutrality Acts of 1935 and 1936 prohibited trade with any belligerents or loans to them、In 1937, the President was empowered to declare an arms embargo in wars between nations at his discretion. American opinion began to change somewhat after President Roosevelt’s “quarantine the ag-gressor” speech at Chicago (1937) in which he severely criticized Hitler’s policies.Germany’s seizure of Austria and the Munich Pact for the partition of Czechoslovakia (1938) also aroused the American people.The conquest of Czechoslovakia in March, 1939, was another rude awakening to the menace of the Third Reich.In August, 1939, came the shock of the Nazi-Soviet Pact and in September the attack on Poland and the outbreak of European war.The United States attempted to maintain neutrality in spite of sympathy for the democracies arrayed against the Third Reich.The Neutrality Act of 1939 repealed the arms embargo and permitted “cash and carry” exports of arms to belligerent nations.A strong national defense program was begun.A draft act was passed (1940) to strengthen the military services.A Lend Act (1941) authorized the President to sell, exchange, or lend materials to any country deemed necessary by him for the defense of the United States.Help was given to Britain by exchanging certain overage destroyers for the right to establish American bases in British territory in the Western Hemisphere.In August, 1940, President Roosevelt and Prime Minister Churchill met and issued the Atlantic Charter, which proclaimed the kind of a world which should be established after the war.In December，1941，Japan launched the unprovoked attack on the United States at Pearl Harbor、Immediately thereafter, Germany declared war on the United States. One item occurring before 1937 that the author does not mention in his list of actions that alienated the American public was________.
A.the burning of the Reichstag

D.the persecution of religious groups
