语篇解读:
本文是一篇议论文。
长期以来,人们认为睡觉前喝一杯热牛奶,但研究表明,只有喝晚上挤的牛奶才真正有助于睡眠。
这到底是什么原因呢?
快来读文章吧!
长难句解读:
Thosegivennightmilk,whichcontained10timestheamountofmelatonin,werelessactiveandlessanxiousthanthosefedwiththemilkcollectedduringdaytime,accordingtothestudypublishedinTheJournalofMedicinalFood.
分析:
本句为复合句。
givennightmilk为过去分词短语作定语修饰其前面的those;which引导的定语从句修饰先行词nightmilk;fedwiththemilk为过去分词作定语修饰其前的those;collectedduringdaytime为过去分词短语作定语修饰其前的milk。
翻译:
由发表在《药物食品杂志》上的研究可知,饮用夜间挤出的牛奶的老鼠比那些饮用白天挤出的牛奶的老鼠更不活跃、更不焦虑,在夜间取自奶牛的牛奶所含的褪黑激素是在白天取自奶牛的牛奶的十倍。
32.B [细节理解题。
由第四段中的信息Thosegivennightmilk...werelessactiveandlessanxiousthanthosefedwiththemilkcollectedduringdaytime...可知,老鼠喝了白天挤的牛奶会更活跃,也更焦虑,故选B项。
]
33.D [推理判断题。
由第六段中的信息takingmelatonindrugshasbeensuggestedtothosewhoarestrugglingtofallasleepatnight可知,褪黑激素被用于安眠药中,故选D项。
]
34.A [标题归纳题。
作者在第一段就点明了文章要论述的对象——晚上挤的牛奶。
在接下来的几段中,作者通过研究人员在老鼠身上做的实验论证了晚上挤出的牛奶与睡眠的关系,故选A项。
]
35.D [推理判断题。
文章的第二、三、四、五段都是讲研究人员的实验及其结果,所以作者是用研究人员的研究结果来支持论点的,故选D项。
