15選10是大英四級改革後閱讀的新題型，有些同學做這種題時會盲目地試答案，這不僅會使正確率下降，還會影響答題時間。其實，做這種題時還是有很多規律可循的。一般將備選分類是最有效的方法，可以按詞性劃分爲名詞、動詞、形容詞和副詞。同樣，平均到這些類別中的詞彙也減少到了3、4個，這樣通過上下文判別空缺單詞的詞性來有的放矢地選擇答案，作對的.機率就會明顯上升。
我覺得這種題型和完型填空還是有相似性的，但要比後者簡單。一些完型中的解題技巧可以運用在15選10中。比如，常見的固定搭配，語法知識點和句子與句子間的邏輯關係等。這裏會涉及到英語語言的2大特點，即篇章的一致性與連貫性。下面我結合實例進行講解。
例：El Nino is the name given to the mysterious and often unpredictable change in the climate of the world. This strange __47__ happens every five to eight years. It starts in the Pacific Ocean and is thought to be caused by a failure in the trade winds, which affects the ocean currents driven by these winds. As the trade winds lessen in __48__ , the ocean temperatures rise, causing the Peru current flowing in from the east to warm up by as much as 5C
The warming of the ocean has far-reaching effects. The hot , humid air over the ocean causes severe __49__ thunderstorms. The rainfall is increased across South America __50__ floods to Peru. In the West Pacific, there are droughts affecting Australia and Indonesia. So while some parts or the world prepare for heavy rains and floods, other parts face drought, poor crops and __51__.
