四級考試閱讀備考筆記（9）

　　Causes are classified as necessary, sufficient, or contributory(起輔助作用的). A necessary cause is one which must be present for the effect to occur, as combustion ，is necessary to drive a gasoline engine. A sufficient cause is one which can produce an effect unaided , though there may be more than one sufficient cause: a dead battery is enough to keep a car from starting, but faulty spark plugs(火花塞)or an empty gas tank will have the same effect. A contributory cause is one which helps to produce an effect but cannot do so by itself, as running through a red light may help cause an accident, though other factors --- pedestrians or other cars in the intersection-must also be present.
