The man, Bob, was alone when he left his Michigan farmhouse on New Years Eve to collect firewood. Expecting a journey of only several meters, Bob was wearing just long johns (衬裤), a shirt and slippers when he went outside, although the temperature was around 4 . After the accident, he was unable to move in the snow. Fortunately, Kelsey came to his assistance. “I was shouting for help, but my nearest neighbor is about 400 meters away, and it was 10：30 pm， ” Bob explained. But my Kelsey came. By the next morning, my voice was gone and I couldnt yell for help, but Kelsey didnt stop barking. Kelseys companion kept him warm by lying on top of him. She licked his face and hands to keep him awake. “Kelsey kept barking but never left my side， ” Bob recalled. “She kept me warm. I knew I couldnt give up and that it was my choice to stay alive.” Bob spent 20 hours in the freezing cold. When he finally lost consciousness, his dog kept barking. Finally, hearing the barking, Bobs neighbor discovered him at 6：30 pm on New Years Day and called the emergency services at once. When Bob arrived in hospital, his body temperature was below 21. However, doctors were surprised to find that he didnt have any frostbite (冻疮). They believed it was because of Kelseys determination to keep him warm. Dr Chaim Colen, the doctor who treated Bob, said, “Animals can help and his dog really saved him . He was very fortunate.” Bob said he was “enormously” grateful to both Dr Colen and his Kelsey. “They saved my life.

When lab rats are not allowed to sleep, they die within a month._1_ One idea is that sleep helps us strengthen new memories. _2_ We know that, while awake, fresh memories are recorded by reinforcing (加强) connections between brain cells, but the memory processes that take place while we sleep have been unclear. Support is growing for a theory that sleep evolved so that connections between neurons (神经元) in the brain can be weakened overnight, making room for fresh memories to form the next day. _3_ Now we have the most direct evidence yet that he is right. _4_ The synapses in the mice taken at the end of a period of sleep were 18 per cent smaller than those taken before sleep, showing that the connections between neurons weaken while sleeping. If Tononis theory is right, it would explain why, when we miss a nights sleep, we find it harder the next day to concentrate and learn new informationour brains may have smaller room for new experiences. Their research also suggests how we may build lasting memories over time even though the synapses become thinner. The team discovered that some synapses seem to be protected and stayed the same size. _5_ “You keep what matters， ” Tononi says. AWe should also try to sleep well the night before. BIts as if the brain is preserving its most important memories. CSimilarly, when people go for a few days without sleeping, they get sick. DThe processes take place to stop our brains becoming loaded with memories. EThats why students do better in tests if they get a chance to sleep after learning. F “Sleep is the price we pay for learning， ” says Giulio Tononi, who developed the idea. GTononis team measured the size of these connections, or synapses, in the brains of 12 mice. 篇章导读：本文是一篇说明文。文章主要讲述了研究发现睡眠可以让记忆变 得更好。 1C首句指出每种动物都要睡觉，但原因仍然是个谜。接下来是具体例 证，如实验室的老鼠被剥夺了睡眠，一个月内就会死亡，同样，人类如果连续几 天不睡觉，就会生病。故选 C。 2E该段首句提出了第一个假设，睡眠帮助我们巩固新的记忆。与这个 论点相呼应的例子是 E 项，该项中的 that 指代的就是前面的假设，也就是说， 这个假设能够解释为什么学生在学习完如果有机会睡一觉，他们会在考试中发挥 更好。 3F由下段首句中的代词 he 可知，该空中必然包含一个人名，否则 he 就 失去了所指对象，浏览各选项，可锁定 F 项和 G 项，但只有 F 项能与本段的内 容衔接，也就是说，睡眠会帮助清除记忆，为新记忆腾出空间。按照研究人员 Tononi 的说法， “睡眠是我们为学习付出的代价” 。 4G该段首句说“现在我们有最直接的证据证明他的假设是对的” ，那接 下来应该是具体描述该证据。此外，该空后面一句话解释了实验的结果和意义。 综合看来，只有 G 项符合语境，指出了研究团队、实验对象及实验内容。 5B由最后一段第二句及空格后的“you keep what matters” (你记住要紧的 事情)可知 B 项“这就好像是大脑在保存最重要的记忆” ，符合语境。 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 答案 Period 2Understanding ideas 课时作业(二) 基础训练 单词拼写 1He took up a _ (位置) in the center of the room. 答案：position 2The investigation will finally _ (确定) what happened on earth. 答案：determine 3He is the typical absentminded _ (教授).

They arrive in Michoacan in late October and discover a right place to spend winter. Once there, they gather together in large masses, which often become so heavy that they cause tree branches to bend or even break. But these butterfly groups can allow butterflies to survive in the low nighttime temperatures. 思维训练 阅读理解 A Many animals recognize their food because they see it. So do humans. When you see an apple or a piece of chocolate you know that you can eat it. You can also use other senses when you choose your food. You may like it because it smells good or because it tastes good. You may dislike some types of food because they do not look, smell or taste very nice. Different animals use different senses to find and choose their food. A few animals depend on only one of their senses, while most animals use more than one sense. Although there are many different types of food, some animals spend their lives eating only one type. The giant panda (大熊猫) eats only one particular type of bamboo (竹子). Other animals eat only one type of food even when given the choice. A kind of white butterfly (蝴蝶) will stay on the leaves of a cabbage, even though there are plenty of other vegetables in the garden. However, most animals have a more varied diet (多样化饮食). The bear eats fruits and fish. The fox eats small animals, birds and fruits. The diet of these animals will be different depending on the season. Humans have a very varied diet. We often eat food because we like it and not because it is good for us. In countries such as France and Britain, people eat food with too much sugar. This makes them overweight, which is bad for their health. Eating too much red meat and animal products, such as butter, can also be bad for the hea
