Next time you gaze outside【C1】______ a cold winter day and think how dead everything appears, take a closer look.
Nature may not be at its【C2】______ in January and February, but it may be the best time to observe amazing adaptations and appreciate the diversity of life even when the temperature falls【C3】______ freezing.
Skunks, chipmunks, and black bears are among the few animals to semi-hibernate during the winter.
The woodchuck is a true hibernator. Many animals【C4】______ to escape the cold. Reptiles may migrate Several inches down into leaf litter or the mud at the bottom of a pond,【C5】______ fish may swim and feed below the ice. Other animals stay active throughout the winter months.
Animal tracks and signs are an excellent【C6】______ to learn about wildlife in winter. Gnawed bark, active lodges, stray feathers, diggings in the ground, urine or scat, or holes in the ice give clues to activity, whether it’s foraging, hunting for prey, finding shelter, or looking for a mate.
Tracks are【C7】______ by their size and shape, the number of toes, the stride, and the mode of locomotion (walking, bounding, galloping, or wadding).
Blowing leaves, cones, or seeds along with falling or rolling snow can also【C8】______ interesting tracks and trails on the snow.
Tracking conditions【C9】______ with the type and amount of snow it’s best to look along the edge of a habitat, such as【C10】______ a forest meets a field, or near water’s edge.

Evidence of insects is also plentiful during the winter. Many insects, with their variety of adaptations, over winter in one of their developmental (sub-adult) stages as either eggs or pupae and emerge in the spring. Insects also have their own version of hibernation in【C12】______ weather, a resting stage called diapause. For some insects, the ratio of light to dark may signal them to migrate to stable environments beneath the ground, below the water’s surface, or into deep water.
Other animals seek protection under the insulating blanket of winter snow. Snow hides prey from 【C13】______ and 【C14】______ dormant plants, insects, and small mammals. Deeper snow requires more energy to move through, but makes it easier for smaller animals to reach buds on tree branches.
Plants also【C15】______ to cold weather with a wide variety of survival techniques. Winter weeds that look dead and dry may have【C16】______ roots underground. Some disperse their seeds on winter winds or produce burs full of【C17】______ that get【C18】______ on the fur of passing animals.
Trees don’t completely stop growing in winter【C19】______ , but they control the growth of their buds and 【C20】______ to the cold and lack of moisture by protecting their buds with scales.
【C10】

A、places
B、where
C、when
D、what
答案
B
解析
本句是考语法。这里的结构需要一个连接词,因为后面是一个主谓结构。由于句子中不缺少主语、谓语、宾语等,因此只能考虑用状语。再根据上下文,这里讲的是地点,所以选择B。
