Question

13．We bet that on cold wintry days，many of you love to stay in your warm home and，every now and then，come out into the kitchen for a snack．Unfortunately，plenty of creepy-crawly critters （爬行生物） like to do the same thing!
    Winter is the time when bugs （虫子） invade your house without an invitation．The season can be tough for such creatures．In winter the air is cold，the ground is hard and many trees have no leaves．So bugs do what they have to do to survive．
    Monarch butterflies head south to warmer climates．Ants crowd in deep underground colonies and eat food they have been storing all year．Many insects go into a deep sleep called diapause．There're different kinds of diapause，but all are similar to hibernation，a time when bigger animals become inactive in the cold．Insects go into an inactive period，too，but it often isn't when the temperature drops．
    They rely on more dependable signals in the environment．For example，many insects can tell how much sunlight there's each day．They use that to tell them when to shut down．Bugs are cold-blooded，meaning that their inside temperature is the same as the outside．They can't move much when it gets below 40 degrees Fahrenheit．So they search for any warm place．
    They're looking for protection．These guys have been doing this for 300 million years，so they don't really know they're coming into your house．The home is a recent event in terms of their evolutionary behavior．They enter through tiny cracks or come in unnoticed on your clothes or shoes．Remember that they may be invading your homes for warmth and food，but they don't care about humans．

A．To point out that humans like to stay at home in winter．
B．To mean that humans and bugs have the same living habits．
C．To mean that bugs will invade the house for their winter．
D．To put forward the idea that bugs are not welcome in winter．
32．According to the text，what is diapause？D
A．It is the same as the animals'hibernation．
B．It often appears in warm areas all the year．
C．It is done to keep bugs active in winter．
D．It is a deep sleep similar to hibernation．
33．What often decides bugs'diapause？C
A．The lower local temperatures．
B．The amounts of sunlight．
C．Kinds of environmental signals．
D．The insects'inside temperature．
34．According to the text，bugs invade humans'homes toC．
A．attack humans                
B．look for enough food
C．seek for protection              
D．show their evolutionary results
35．What would be the best title for the text？B

Answer 1

分析 本文主要介绍的是：为什么虫子在冬天会入侵人类住所？

解答 31--35．CDCCB
31．C 推理判断题．根据第一段可知，虫子和人类一样，也会喜欢待在温暖的屋里，再结合文章的后面几段可知，本段暗示虫子在冬天会入侵人类住所．故选C．
32．D 细节理解题．根据第三段Many insects go into a deep sleep called diapause．There're different kinds of diapause，but all are similar to hibernation，a time when bigger animals become inactive in the cold可知，虫子经过"diapause"的目的是度过缺少光照等条件的冬季，类似于冬眠的长时间睡觉，但并不是冬眠，更不是为了确保冬天的活跃状态．故选D．
33．C 细节判断题．根据文章第四段的"They rely on more dependable signals in the environment"可知，虫子的"diapause"是由它们的多种依赖因素的变化所决定的，不一定全靠温度或者光照．故选C．
34．C 细节理解题．根据最后一段They're looking for protection可知，虫子进屋是为了寻求保护，把自己置身于安全形势之下，而不仅仅是为了寻求食物．故选C．
35．B 主旨大意题．整篇文章主要告诉读者的是：在冬天里，为什么虫子会入侵人类的住所．
