题目内容
20．Everythingthathe did seemed reasonable．分析 他做的一切都似乎是合理的．
解答 that 考查定语从句．先行词是everything，在定语从句he did中做did的宾语，又因为先行词是不定代词everything，所以答案填关系代词that．
点评 定语从句又称为形容词性从句，综观历年高考试题，我们可以发现该语法项目是测试中的热点与难点，解定语从句的题目首先要知道哪一句是主句，哪一句是从句，被修饰的词是谁，从句中的句子成分缺失什么，根据缺失成分的不同从而选出相对应的关系代词或者关系副词，从而选出正确的答案，解题的关键是从句句子的成分分析．

15．Sleep，as mysterious as it is vital for our wellbeing，is part of a person's daily physiological activity．Over the decades，researchers have proposed several mechanisms through which sleep helps us（41）C，but we still don't fully（42）Athe big picture．Now，two recently published studies come up with an interesting（43）B：we sleep to forget some of the things we learn during the day．
We store memories in networks in our brains．Whenever we learn something new，we（44）Cnew connections between neurons（神经元），called synapses（突触）．In 2003，two biologists proposed something very（45）D：during the day，we learn so much and develop so many synapses that things（46）Dget ourselves confused．
For starters，they showed that neurons can prune out（修剪）some synapses，at least in the lab．But they（47）Cthe same things happens every day，naturally，in our brains-probably during（48）B．
So they set up a painstaking experiment，in which an assistant scientist collected 6，920synapses from （49）A，both awake and sleeping．Then，they（50）Athe shape and size of all these synapses，learning that the synapses in sleeping mice were 18percent smaller than in awake ones．
After this，they designed a（51）Ctest for mice．They placed the animals in a room where they would get a mild electrical shock if they walked over one particular （52）Cof the floor．They injected（注射）some of them with a substance that had been proved to prevent the pruning of new synapses．The mice that experienced this were（53）Alikely to forget about the section and after a good night's sleep，they（54）Bto walk as usual，while mice that slept normally remembered better．
Then，they found that the pruning didn't strike every neuron．Some 20% were unchanged，likely well-established memories that shouldn't be tampered with（被窜改）．In other words，we sleep to（55）A-but in a smart way．
