1、 More Than 8 Hours Sleep Too Much of a Good Thing 1 Although the dangers of too little sleep are widely known, new research suggests that people who sleep too much may also suffer the consequences. 2 Investigators at the University of California in San Diego found that people who clock up 9 ｏｒ10 hours each weeknight appear to have more trouble falling ａｎｄ　staying asleep, as well as a number of other sleep problems, than people who sleep 8 hours a night. People who slept only 7 hours each night also said they had more trouble falling asleep arid feeling refreshed after a night\'s sleep than 8-hour sleepers. 3 These findings, which Dr. Daniel Kripke reported in the journal Psychosomatic Medicine, demonstrate that people who want to get a good night\'s rest may not need to ｓｅｔaside more than 8 hours a night. He added that "it might be a good idea" fｏｒpeople who sleep more than 8 hours each night to consider reducing the amount of time they spend in bed, but cautioned that more research is needed to confirm this. 4 Previous studies have shown the potential dangers of chronic shortages of sleep, fｏｒinstance, one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more. 5 Fｏｒthe current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how much they slept during the week ａｎｄ　whether they experienced any sleep problems. Sleep problems included waking in the middle of the night, arising early in the morning ａｎｄ　being unable to fall hack to sleep, ａｎｄ　having fatigue interfere with day-to-day functioning. 6 Kripke found that people who slept between 9 ａｎｄ　10 hours each night were more likely to report experiencing each sleep problem than people who slept 8 hours. In an interview, Kripke noted that long sleepers may struggle to get rest at night simply because they spend too much time in bed. As evidence, he added that one way to help insomnia is to spend less time in bad. "It stands to reason that if a person spends too long a time in bed, then they\'ll spend a higher percentage of time awake," he said. One survey showed that people who habitually each night have a higher risk of dying____. 【单选题】

A.fall asleep again

B. become more energetic the following day

C.sleep less than 10 hours

D.confirm those serious consequences

E.suffer sleep problems

F.sleep more than 11 hours

正确答案:C

答案解析:本题答案的依据是第四段：one report demonstrated that people who habitually sleep less than 7 hours each night have a higher risk of dying within a fixed period than people who sleep more.

2、Parkinson\'s Disease1. Parkinson\'s disease affects the way you move. It happens when there is a problem with certain nerve cells in the brain. Normally, these nerve cells make an important chemical called dopamine(多巴胺). Dopamine sends signals to the part of your brain that controls movement. It lets your muscles move smoothly ａｎｄ　do what you want them to do. When you have Parkinson\'s, these nerve cells break down. Then you no longer have enough dopamine, ａｎｄ　you have trouble moving the way you want to.2. No one knows fｏｒsure what makes these nerve cells break down. But scientists are doing a lot of research to look fｏｒthe answer. They are studying many possible causes, including aging ａｎｄ　poisons in the environment. Abnormal genes seem to lead to Parkinson\'s disease in some people. But so far, there is not enough proof to show that it is always inherited.3. Tremｏｒ(颤抖) may be the first symptom you notice. It is one of the most common signs of the disease, although not everyone has it. Tremｏｒoften starts in just one arm ｏｒleg ｏｒonly on one side of the body. It may be worse when you are awake but not moving the affected arm ｏｒleg. It may get better when you move the limb ｏｒyou are asleep. In time, Parkinson\'s affects muscles all through your body, so it can lead to problems like trouble swallowing ｏｒconstipation(便秘) . In the later stages of the disease, a person with Parkinson\'s may have a fixed ｏｒblank expression, trouble speaking, ａｎｄ　other problems. Some people also have a decrease in mental skills.4. At this time, there is no cure fｏｒParkinson\'s disease. But there are several types of medicines that can control the symptoms ａｎｄ　make the disease easier to live with. You may not even need treatment if your symptoms are not obvious. Your doctｏｒmay wait to prescribe medicines until your symptoms start to get in the way of your daily life. Your doctｏｒwill adjust your medicines as your symptoms get worse. You may need to take several medicines to get the best results.One of the most common signs of Parkinson\'s is tremor, ______.【单选题】

A.if there isn’t enough dopamine in your body

B.what affects muscles all through your body

C.which cannot be cured yet

D.if you have a fixed ｏｒblank expression

E.which may be the first symptom you notice

F.what causes Parkinson\'s disease

正确答案:E

答案解析:本题难度不大，带着题干信息词回文章定位，答案依据是文章第三段的第一句：Tremｏｒmay be the first symptom you notice，谈到颤抖会是你注意到的第一个症状，回来看选项，E项和原文句意相符，是答案。

4、Blasts from the Past1 Volcanoes were more destructive in ancient history. Not because they were bigger, but because the carbon they released wiped out life with greater ease.2 Paul Wignall from the University of Leeds was investigating the link between volcanic eruptions ａｎｄ　mass extinctions. Not all volcanic eruptions killed off large numbers of animals, but all the mass extinctions over the past 300. million years coincided with huge formations of volcanic rock. To his surprise, the older the massive volcanic eruptions were, the more damage they seemed to do.3 Wignall calculated the "killing efficiency" fｏｒthese volcanoes by comparing the proportion of life they killed off with the volume of lava that they produced. He found that size fｏｒsize, older eruptions were at least 10 times as effective at wiping out life as their more recent rivals.4 The Permian extinction, fｏｒexample, which happened 250 million years ago, is marked by floods of volcanic rock in. Siberia that cover an area roughly the size of western Europe, Those volcanoes are thought to have pumped out about 10 gigatonnes of carbon as carbon dioxide, The global warming that followed wiped out 8 per cent of all marine genera at the time, ａｎｄ　it took 5 million years far tire planet to recover.5 Yet 60 million years ago in the late Palaeocene there was another huge amount of volcanic activity ａｎｄ　global-warming but no mass extinction. Some animals did disappear but things returned to normal within ten thousands of years, "The most recent ones hardly have an effect at all," Wignall says. He ignored the extinction which wiped out the dinosaurs at the end of the Cretaceous, 65 million years ago, because many scientists believe it was primarily caused by the impact of an asteroid.6 Wignall thinks that older volcanoes had more killing power because more recent life forms were better adapted to dealing with increased levels of C02 Ocean chemistry may also have played a role. As the supercontinents broke up ａｎｄ　exposed more coastline there may have been more weathering of silica rocks. This would have encouraged the growth of phytoplankton in the oceans, increasing the amount of C02 absorbed from the atmosphere.7 Vincent Courtillot, directｏｒof the Paris Geophysical Institute in France, says that Wignall\'s idea is provocative. But he says it is incredibly hard to do these sorts of calculations. He points out that the killing power of volcanic eruptions depends on how long they fasted. ａｎｄ　it is impossible to tell whether the huge blasts lasted fｏｒthousands ｏｒmillions of years.8 Courtillot also adds that it is difficult to estimate how much lava prehistoric volcanoes produced, ａｎｄ　that lava volume may not necessarily correspond to carbon dioxide ｏｒsulphur dioxide emissions.The cause of the extinction of dinosaurs____.【单选题】

A.than more recent ones

B.the killing efficiency fｏｒolder eruptions

C.has remained controversial

D.Wignall\'s calculations as acceptable

E.has been mown to us all

F.his ideas

正确答案:C

答案解析:has remained controversial：-直是有争议的。把这一选项跟题干合成后生成的句子说的是：有关恐龙灭绝的原因一直是有争议的。第五段有这么一句话：…because many scientists believe it was primarily caused by the impact of an asteroid. 因为许多科学家相信恐龙的灭绝主要是由于一颗小行星的影响造成的。“许多科学家”当然不是全部。“有关恐龙灭绝的原因一直是有争议的”这个命题是可以从这句话中推断出来的。

B.what affects muscles all through your body

C.which cannot be cured yet

D.if you have a fixed ｏｒblank expression

E.which may be the first symptom you notice

F.what causes Parkinson\'s disease

正确答案:A

答案解析:如果你的体内没有足够多的多巴胺，那么你会发现活动起来有困难。根据第一段最后一句： Then you no longer have enough dopamine, ａｎｄ　you have trouble moving the way you want to. 因此选A。
