Energy Cycle
Do you find getting up in the morning so difficult that it's painful?This might be called laziness,but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.
During the hours when you labor through your work you may say that you're“hot”.That's true .The time of day when you feel most energetic is when your cycle of body temperature is at its peak .For some people the peak comes during the morning. For others it comes in the afternoon or evening.No one has discovered why this is so,but it leads to such familiar monologues as:“Get up,John!You'll be late for work again!”The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.
You can't change your energy cycle,but you can learn to make your life fit to it better. Habit can help,Dr. Kleitman believes. Maybe you're sleepy in the evening but you must stay up late anyway .Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day,rise before your usual hour. This won't change your cycle,but you'll get up steam and work better at your low point.
Get off to a slow start which saves your energy .Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the trouble of searching for clean clothes by laying them out the night before .Whenever possible,do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours.

参考答案
参考解析
解析：根据第一段可以看出，早晨起不来与个人每天的能量周期有关。根据文章第二段中约翰自言自语以及紧接着的解释“Get up , John ! You'll be late for work again ! ” The explanation… temperature-and-energy peak in the evening．可推断出答案。
答案的线索在第二段最后一句话“Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.”也就是说，如果丈夫和妻子能明白不同的能量周期是怎么回事，家里每个人有什么样的能量周期，很多家庭争吵就不会发生。所以正确答案是A。
“如果一个人想在早上能量低潮时更有效地工作，那么他该怎么办？”根据这两句话“If your energy is low in the morning but you have…but you'll get up steam and work better at your low point.”可以断定正确答案应该是C。
“建议你早上起床时打个呵欠，伸伸懒腰，因为它们会＿______”首先应理解文章最后一段的第一句话“get off to a slow start which saves your energy”，还要理解该句后面的三句话，它们是保存能量的具体方法。“Get up with a leisurely yawn and stretch”当然是为了保存能量。所以正确答案是A。
选项B说Dr. Kleitman解释了为什么人们在一天里的不同时刻会有不同的能量高峰。而文章第二段指出没有人发现为什么会有不同的能量周期“For some people the peak comes during morning…No one has discovered why this is so.”两者不符，所以正确答案是B。

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）. Dopa-mine 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 longerhave enough dopamine,and you have trouble moving the way you want to.2 No one knows for sure what makes these nerve cells break down.But scientists are doing a lot of re-search to look for the answer. They are studying many possible causes,including aging and poisons in the en- vironment.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.Tremor often starts in just one arm or leg or only on one side of the body.It may be worse when you are awake but not moving the affected arm or leg. It may get better when you move the limb or when you are asleep.In time,Parkinson's affects muscles all through your body,so it can lead to problems like trouble swallowing or constipation（便秘）.In the later stages of the disease , a person with Parkinson's may have a fixed or blank expression,trouble speaking,and other problems.Some people also have a decrease in mental skills.4 At this time,there is no cure for Parkinson'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 mild.Your doctor may wait to prescribe medicines until your symptoms start to get in the way of your daily life.Your doctor will adjust your medicines as your symptoms get worse.You may need to take several medicines to get the best results.A person with Parkinson's has to learn to live with the disease,__________.A:what affects muscles all through your bodyB:if there isn't enough dopamine in your bodyC:which cannot be cured yetD:which may be the first symptom you noticeE:if you have a fixed or blank expression F: what causes Parkinson's disease

Fermi ProblemOn a Monday morning in July,the world's first atom bomb exploded in New Mexico desert. Forty seconds later,the shock waves reached the base camp where the Italian-American physicist Enrico Fermi and his team stood.After a mental calculation,Fermi announced to his team that the bomb's energy had equated 10,000 tons of TNT. The bomb team was impressed,but not sur-prised.Fermi's genius was known throughout the scientific world.In 1938 he had won a Nobel Prize.Four years later he produced the first nuclear chain reaction,leading us into the nuclear age .Since Fermi's death in 1954,no physicist has been at once a master experimentalist（实验室）and a leading theoretician（理论学家）.Like all virtuosos（大师）,Fermi had a distinctive style. He preferred the most direct route to an answer. He was very good at dividing difficult problems into small,manageable bits talent we all can use in our daily lives.To develop this talent in his students,Fermi would suggest a type of question now known as a Fermi problem.Upon first hearing one of these,you haven't the remotest notion of the answer, and you feel certain that too little information had been given to solve it. Yet when the problem is broken into sub-problems,each answerable without the help of experts or books,you can come close to the exact solution.Suppose you want to determine earth's circumference without looking it up.Everyone knows that New York and Los Angeles are about 3,000 miles apart and that the time difference between them is three hours.Three hours is one-eighth of a day,and a day is the time it takes the planet to complete one rotation（旋转）,so its circumference must be eight times 3 ,000 or 24,000 mi-les .This answer differs from the true value,24,902 .45 miles,by less than four percent.Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries and inventions.It doesn't matter whether the discovery is as important as determining the power of an atom or as small as measuring the distance between New York and Los Angeles.Looking up the answer,or letting someone else find it,deprives you of the pleasure and pride that accompany creativity,and deprives you of an experience that builds up self-confidence.Thus,approaching personal dilemmas as Fermi problems can become a habit that enriches your life. Dividing a big problem into small problems is a talent Fermi had and a talent that has practi- cal value in life.A: RightB: WrongC: Not mentioned

How to Get Along Well With Your Boss1 Before you argue with your boss,check with the boss's secretary to determine his mood.If he ate nails for breakfast,it is not a good idea to ask him for something.Even without the boss's secretary,there are keys to timing:don't approach the boss when he's on deadline,don't go in right before lunch,when he is apt to be distracted and rushed,don't go in just before or after he has taken a vacation.2 If you're mad,that will only make your boss mad.Calm down first,and don't let a particular concern open the floodgates for all your accumulated frustration.The boss will feel that you think negatively about the company and it is hopeless trying to change your mind.Then maybe he will dismiss you.3 Terrible disputes can result when neither the employer nor the employee knows what is the problem the other wants to discuss.Sometimes the fight will go away when the issues are made clear.The employee has to get his point across clearly in order to make the boss understand it.4 Your boss has enough on his mind without your adding more.If you can't put forward an immediate solution,at least suggest how to approach the problem.People who frequently present problems without solutions to their bosses may soon find they can't get past the secretary.5 To deal effectively with a boss,it's important to consider his goals and pressures.If you can put yourself in the position of being a partner to the boss,then he will be naturally more inclined to work with you to achieve your goals.If you want to ask the boss for anything,it is important to find out first______.A:to give the boss your adviceB:how he is feelingC:the boss may haveD:what you really want to talk to him aboutE:without suggesting a way to solve it F:how unhappy you are

What Is Insulin-dependent Diabetes?When you eat,your body takes the sugar from food and turns it into fuel.______(46)Your body uses glucose for energy,so it can do everything from breathing air to playing a video game.But glucose can't be used by the body on its own-it needs a hormone called insulin to bring it into the cells of the body.Most people get the insulin they need from the pancreas,a large organ near the stomach?The pancreas makes insulin;insulin brings glucose into the cells;and the body gets the energy it needs.When a person has insulin一dependent diabetes,it's because the pancreas is not making insulin.So someone could be eating lots of food and getting all the glucose he needs,but without insulin,there is no way for the body to use the glucose for energy.______(47)You may have heard older people talk about having diabetes,maybe people of your grandparents'age.Usually,this is a different kind of diabetes called non一insulin一dependent diabetes.It can also be called Type 2 diabetes,or adult-onset diabetes.______(48) When a kid is diagnosed with juvenile(insulin-dependent)diabetes,he will have that type of diabetes for his whole life.It won't ever change to non-insulin-dependent diabetes when he gets older.Scientists now think that a person who has juvenile diabetes was born with a certain gene or genes that made the person more likely to get the illness.______(49)Many scientists believe that along with having certain genes,something else outside the person's body, like a viral infection,is necessary to set the diabetes in motion by affecting the cells in the pancreas that make insulin.But the person must have the gene(or genes)for diabetes to start' out with一this means you can't get diabetes just from catching a flu,virus,or cold.And this type of diabetes isn't caused by eating too many sugary foods,either.Diabetes can take a long time to develop in a person's body-sometimes months or years?Another important thing to remember is that diabetes is not contagious.______(50)______(47)A:Genes are something that you inherit from your parents,and they are in your body even before you're born.B:This sugar-fuel is called glucose?C:It may be possible to beat insulin resistance through lifestyle changes.D:You can't catch diabetes from people who have it,no matter how close you sit to them or if you kiss them.E:The glucose can't get into the cells of the body without insulin.F:When a person has this kind of diabetes,the pancreas usually can still make insulin,but the person's body needs more than the pancreas can make?

Energy CycleDo you find getting up in the morning so difficult that it's painful?This might be called laziness,but Dr. Kleitman has a new explanation. He has proved that everyone has a daily energy cycle.During the hours when you labor through your work you may say that you're“hot”.That's true .The time of day when you feel most energetic is when your cycle of body temperature is at its peak .For some people the peak comes during the morning. For others it comes in the afternoon or evening.No one has discovered why this is so,but it leads to such familiar monologues as:“Get up,John!You'll be late for work again!”The possible explanation to the trouble is that John is at his temperature-and-energy peak in the evening. Much family quarrelling ends when husbands and wives realize what these energy cycles mean,and which cycle each member of the family has.You can't change your energy cycle,but you can learn to make your life fit to it better. Habit can help,Dr. Kleitman believes. Maybe you're sleepy in the evening but you must stay up late anyway .Counteract your cycle to some extent by habitually staying up later than you want to. If your energy is low in the morning but you have an important job to do early in the day,rise before your usual hour. This won't change your cycle,but you'll get up steam and work better at your low point.Get off to a slow start which saves your energy .Get up with a leisurely yawn and stretch.Sit on the edge of the bed a minute before putting your feet on the floor. Avoid the trouble of searching for clean clothes by laying them out the night before .Whenever possible,do routine work in the afternoon and save tasks requiring more energy or concentration for your sharper hours. Which of the following statements is NOT TRUE?A: Getting off to work with a minimum effort helps save one's energy.B: Dr. Kleitman explains why people reach their peak at different hours of day.C: Habit helps a person adapt to his own energy cycle.D: Children have energy cycles,too.

How to Get Along Well With Your Boss1 Before you argue with your boss,check with the boss's secretary to determine his mood.If he ate nails for breakfast,it is not a good idea to ask him for something. Even without the boss's secretary,there are keys to timing don't approach the boss when he's on deadline,don't go in right before lunch,when he is apt to be distracted and rushed,don't go in just before or after he has taken a vacation.2 Ifyou're mad,that will only make your boss mad.Calm down first.And don't let a particular concern open the floodgates for all your accumulated frustration.The boss will feel that you think negatively about the company and it is hopeless trying to change your mind.Then maybe he will dismiss you.3 Terrible disputes can result when neither the employer nor the employee knows what is the problem the other wants to discuss.Sometimes the fight will go away when the issues are made clear. The employee has to get his point across clearly in order to make the boss understand it.4 Your boss has enough on his mind without your adding more.If you can't put forward an immediate solution,at least suggest how to approach the problem.People who frequently present problems without solu- tions to their bosses may soon find they can't get past the secretary.5 To deal effectively with a boss,it's important to consider his goals and pressures.If you can put yourself in the position of being a partner to the boss,then he will be naturally more inclined to work with you to achieve your goals.If you want to ask the boss for anything,it is important to find out first_________.A:to give the boss your adviceB:how he is feelingC:the boss may haveD:what you really want to talk to him aboutE:without suggesting a way to solve it F: how. unhappy you are
