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 （蟲子） 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．

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．

Answer 1

分析 本文主要介紹的是：為什么蟲子在冬天會入侵人類住所？

解答 31--35．CDCCB
31．C 推理判斷題．根據(jù)第一段可知，蟲子和人類一樣，也會喜歡待在溫暖的屋里，再結(jié)合文章的后面幾段可知，本段暗示蟲子在冬天會入侵人類住所．故選C．
32．D 細節(jié)理解題．根據(jù)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，蟲子經(jīng)過"diapause"的目的是度過缺少光照等條件的冬季，類似于冬眠的長時間睡覺，但并不是冬眠，更不是為了確保冬天的活躍狀態(tài)．故選D．
33．C 細節(jié)判斷題．根據(jù)文章第四段的"They rely on more dependable signals in the environment"可知，蟲子的"diapause"是由它們的多種依賴因素的變化所決定的，不一定全靠溫度或者光照．故選C．
34．C 細節(jié)理解題．根據(jù)最后一段They're looking for protection可知，蟲子進屋是為了尋求保護，把自己置身于安全形勢之下，而不僅僅是為了尋求食物．故選C．
35．B 主旨大意題．整篇文章主要告訴讀者的是：在冬天里，為什么蟲子會入侵人類的住所．
