Question

A little snail （蜗牛）felt tired from carrying his shell all day．He asked his mother，"Mom，why do we have to carry our shells？"
His mother told him，"Because we don't have any bones（骨头）in our body．We can only crawl （爬），The hard shell not only helps us move faster but also protect us．"
The little snail was still puzzled，"Caterpillars（蝴蝶的幼虫）don't have bones，either．They can't even crawl．But they don't need to carry heavy shells．"
The mother smiled and said，"Caterpillars turn into butterflies when they grow up．The sky will protect them．"
"How about earthworms？They don't have bones，they don't crawl fast and they don't turn into butterflies．And they don't have to carry heavy shells．"The mother told him，"Earthworms live underground and the land protects them．"
The little snail started to cry，"How poor we are!"The mother snail comforted （安慰）him，"That's why we have shells！We don't depend on the sky．We don't depend on the land．We depend on ourselves．"

Answer 1

56．B 细节理解题．根据A little snail （蜗牛）felt tired from carrying his shell all day．可知小蜗牛整天背着壳他感到很累．故选B．
57．D 细节理解题．根据蜗牛妈妈说的话，"The hard shell not only helps us move faster but also protect us．"可知因为壳很有用，所以才必须背着它．故选D．
58．A 词义理解题．根据后面小蜗牛的话"Caterpillars（蝴蝶的幼虫）don't have bones，either．They can't even crawl．But they don't need to carry heavy shells．"可知小蜗牛不理解为什么毛毛虫也没有壳，甚至不会爬，他们就不需要背着重重的壳呢？所以可以推测小蜗牛对妈妈的话仍然感到疑惑不解．所以此处puzzle的词义是形容词"疑惑不解的"．故选A．
59．C 推理判断题．根据蜗牛妈妈说的话，"That's why we have shells！We don't depend on the sky．We don't depend on the land．We depend on ourselves．"可以推测出小蜗牛对于这种独立的不依靠任何人的蜗牛精神会引以为豪，进而会改变对壳的看法，所以推测可能会对自己的壳变得非常满意．故选C．
60．D 主旨大意题．根据文章最后蜗牛妈妈的话，即文章的主题句"That's why we have shells！We don't depend on the sky．We don't depend on the land．We depend on ourselves．"可知本文作者想告诉我们必须依靠自己的道理．故选D．
