When I visited a number of fruit farms in central England.I found broad agreement-|||-among most of the growers that these days it makes sense to move away from their-|||-traditional crops such as apples and into cherries instead.Now.in summertime.they-|||-have orchard after orchard of beautiful trees,heavily laden with bright red fruit.-|||-UK cherry growers tend to choose the varieties which ripen slowly.This fruit may-|||-command a higher price because the harvest is not so early,and there are always reliable-|||-buyers for it.Research is currently being carried out into ways of improving yield.A-|||-major obstacle to cfficient production is the fact that growth may not be the same from-|||-season to season.Sometimes the fruit only grows as big as a pea,and then drops to the-|||-ground.-|||-Quite a few of the smaller trees are covered up against the rain and wind.in a-|||-plastic tunnel.Older.larger trees have to take their chance out in the open,but cherries-|||-are a delicate fruit,and good weather conditions are needed to achieve the potential-|||-yield of five tons per hectare.The surface of the fruit has very little wax on it,so cherries-|||-need to be kept out of the rain as much as possible,because it's easy for the skin to-|||-crack when water gets into it.If this occurs.the crop may be lost,because the fruit-|||-bursts with a pop,rather like a balloon-|||-People often ask,"How long does it take to get a decent crop from a cherry tree?"-|||-Well,there are new varieties.laden with fruit,that are only four years old.but if you-|||-go back and read the old fruit-growing textbooks from the 1960s,they tell you cherries-|||-don't give a worthwhile crop till they're 12 years old.Some varieties go on cropping-|||-till they're 90!-|||-There are three new varieties which have recently been introduced by growers-|||-'Symphony'and Staccato'are both highly successful so far.but Sweetheart is being-|||-planted in larger numbers than either of them and looks to be a real winner.-|||-Just one problem if you go o cherry picking this summer-how do you stop yourself-|||-eating them all?One expert who's been picking all her life told me,"Eat a cherry,suck-|||-the stone and keep it on your tongue-it stops you putting any more in!"That way you-|||-end up with at least a handful of this delicious fruit in your basket!-|||-36.It can be inferred from the passage that many fruit growers in central England-|||-__-|||-A)favor traditional varieties of cherry-|||-B)used to grow apples in their orchards-|||-C)are eager to raise the price of their fruit-|||-D)have lost many buyers in their business-|||-37.What should be done in order to get a big harvest of cherries?-|||-A)Cover up the cherries with paper bags-|||-B)Spray wax onto the surface of cherries-|||-C)Shelter the cherries from rain and wind-|||-D)Water the cherry trees frequently.-|||-38.How are the new varieties of cherry trees different from traditiona ones?-|||-A)They produce a larger crop than traditional ones.-|||-B)They can be harvested for more than one season.-|||-C)They give cherries with better taste.-|||-D)They take less time to yield a crop.
