问题 共用题干Adaptation of Living Things
Certain animals and plants develop characteristics that help them cope with their environment better than others of their kind.This natural biological process is called adaptation.Among the superior characteristics developed through adaptationare those that may help in getting food or shelter,in providing protection,and in producing and protecting the young.That results in the evolution of more and more organisms（微生物）that are better fitted to their environments.
Each living thing is adapted to its way of life in a general way,but each is adapted especially to its own distinct class.A plant,for example,depends upon its roots to fix itself firmly and to absorb water and inorganic（无机的）chemicals.It depends upon its green leaves for using the sun's energy to make food from inorganic chemicals.These are general adaptations,common to most plants.In addition,there are special adaptations that only certain kinds of plants have.
Many animals have adaptations that help them escape from their enemies.Some insects are hidden by their body color or shape,and many look like a leaf or a little branch.The coats of deer are colored to mix with the surroundings.Many animals have the ability to remain completely still when an enemy is near.
Organisms have a great variety of ways of adapting.They may adapt.in their structure,function,and genetics;in their development and production of the young;and in other respects.An organism may create its own environment,as do warm-blooded mammals（哺乳动物）,which have the ability to adjust body heat exactly to maintain their ideal temperature despite changing weather.Usually adaptations are an advantage,but sometimes an organism is so well adapted to a particular environment that,if conditions change,it finds it difficult or impossible to readapt to the new conditions.The author cites the behavior of warm-blooded mammals in order to illustrate that______.A:a living thing may have the ability to create an environment of its ownB:a living creature may have the ability to remain still when an enemy is nearC:a living creature may have the ability to make food from its inorganic chemicalsD:a living creature may have the ability to change the color of its skin
选项 The author cites the behavior of warm-blooded mammals in order to illustrate that______.
A:a living thing may have the ability to create an environment of its own
B:a living creature may have the ability to remain still when an enemy is near
C:a living creature may have the ability to make food from its inorganic chemicals
D:a living creature may have the ability to change the color of its skin
答案 A
解析 根据第一段第一句可知，某些动植物进化出优越的特性，是为了比同类中的其他个体’能更好地适应环境。C项中的“adapted”是该句中“cope with”的同义转换，所以选择C项。
