1．The main idea of the first paragraph is that________.A．some fish can adjust to warmer watersB．some fish can grow bigger at present­day temperaturesC．some fish may die out in cooler watersD．big fish can survive the temperature changeA [根据文章第一段的最后一句“But recent studie s have shown that some fish are able to adapt to warmer waters over a few generations.”可知，最近的研究表明一些鱼将会适应更温暖的水域，故正确答案为A。

]2．One specific kind of fish adjusts to the changed surroundings by________.A．switching their genes on and offB．growing quicklyC．training their ability to swimD．living in a groupA [根据第二段中的“...one key tropical fish species did this by turning on andoff some of its genes.”可知，这种鱼通过改变基因来适应周围环境的变化，故正确答案为A。

]3．From Donelson's experiment，we know________.A. the clownfish she raised are from the Great Barrier ReefB．she raised the fish in two different temperature conditionsC．after a year's growing，the fish failed to adjust to warmer temperatures D．the fish raised in the warmest water grow largest and heaviestD [根据第三段第一句中的“...which live in coral reefs throughout the West Pacific.”可知A项错误；根据第三段中的“She kept one group...”和“...she kept another group...and a third group...”可知，她养了三组小丑鱼，B项错误；根据第四段的内容可知，一年后，小丑鱼适应了更温暖的温度，并且在温度最高的水域里，小丑鱼长得最大最重，C项错误，故正确答案为D。
