B. Dangers of Habitual Shortages of Sleep

C. Classification of Sleep Problems

D. A Way of Overcoming Insomnia

E. Sleep Problems of Long and Short Sleepers

F. Oversleeping — 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 or 10 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 and feeling refreshed after a night’s sleep than 8-hour sleepers.

3. ______

Previous studies have shown the potential dangers of chronic(慢性的) shortages of sleep — for instance, 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.

4. ______

For the current report, Kripke reviewed the responses of 1,004 adults to sleep questionnaires, in which participants indicated how mush 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 back to sleep, and having tiredness interfere with day-to-day functioning.

5. ______

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 bed. “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.

Tips for
Being a Good Neighbor
【小題1】_______________
No one likes a noisy neighbor. Do you hold parties that last all night? Do you leave your dog outside to bark all day? Remember that not everyone has the same schedule as you do, so use some common sense. Keep noise to the lowest level. If you’re holding a party that’s likely to be loud, invite everyone within earshot(聽力范圍)。
【小題2】________________
It’s much easier to solve any problem with neighbors if you have a friendly relationship with those around you. Furthermore, you may realize that you have things in common and make a lifelong friend.
【小題3】_________________
Once you know your neighbors, then you’ll also know if something seems out of place in the neighborhood. Are strange people carrying expensive things out of one neighbor’s house? Have several days passed since your elderly neighbor last collected his newspaper? The benefit of keeping an eye out for unusual behavior in the neighborhood is that others will do the same for you.
【小題4】___________________
It never hurts to follow the Golden Rule: Do to others what you would like them to do to you. Treat your neighbors with respect. Offer to drive an elderly neighbor to the grocery store. Volunteer to collect mail while a neighbor is on vacation. The more often you lend a helping hand, the more likely that your neighbors will do the same for you when you need a little help.
【小題5】_____________________
Don’t just limit your neighborly actions to your block or street. Remember that everyone who lives in a community has the ability to help make it a better place. Think about your passion and find a way to do it on a volunteer basis in your town. Volunteer at the local library. Enjoy working with kids. Consider becoming a scout (童子軍)leader. Whatever your passion is, there’s sure to be a thing suitable for you to help in the local community.

Five Simple Ways to Increase Your Intelligence
Your brain needs exercise just like a muscle. If you use it often and in the right ways, you will become a more skilled thinker and increase your ability to focus.
Here are 5 simple ways anyone can squeeze a bit more productivity out of the old gray matter.
【小題1】_______– This is a hard sell. People love vegetating in front of the television, myself included more often than I’d like. The problem is watching television doesn’t use your mental capacity OR allow it to recharge. It’s like having the energy sapped out of a muscle without the health benefits of exercise.
When you feel like relaxing, try reading a book instead. If you’re too tired, listen to some music. When you’re with your friends or family, leave the tube off and have a conversation. All of these things use your mind more than television and allow you to relax.
【小題2】_______ – I used to think that I’d learn more by not exercising and using the time to read a book instead. But I realized that time spent exercising always leads to greater learning because it improves productivity during the time afterwards. Using your body clears your head and creates a wave of energy. Afterwards, you feel invigorated and can concentrate more easily.
【小題3】_______– Many people like to read popular suspense fiction, but generally these books aren’t mentally stimulating. If you want to improve your thinking and writing ability you should read books that make you focus. Reading a classic novel can change your view of the world and will make you think in more precise, elegant English. Don’t be afraid to look up a word if you don’t know it, and don’t be afraid of dense passages. Take your time, re-read when necessary, and you’ll soon grow accustomed to the author’s style.
【小題4】________– Nothing makes it harder to concentrate than sleep deprivation. You’ll be most rejuvenated if you go to bed early and don’t sleep more than 8 hours. If you stay up late and compensate by sleeping late, you’ll wake up lethargic(無精打采) and have trouble focusing. In my experience the early morning hours are the most tranquil and productive. Waking up early gives you more productive hours and maximizes your mental acuity(敏銳) all day.
If you have the opportunity, take 10-20 minute naps when you are hit with a wave of drowsiness. Anything longer will make you lethargic, but a short nap will refresh you.
【小題5】________ – Often our lives get so hectic that we become overwhelmed without even realizing it. It becomes difficult to concentrate because nagging thoughts keep interrupting. Spending some time alone in reflection gives you a chance to organize your thoughts and prioritize your responsibilities. Afterwards, you’ll have a better understanding of what’s important and what isn’t. The unimportant stuff won’t bother you anymore and your mind will feel less encumbered.
Conclusion – I hope you aren’t disappointed that none of the techniques I’ve proposed are revolutionary. But simple, unexciting answers are often the most valid. The challenge is having the will to adhere to them. If you succeed in following these 5 tips, you’ll be rewarded with increased mental acuity and retention of knowledge.

下面文章中有5處需要添加小標(biāo)題。請從以下選項(xiàng)（A,B,C,D,E和F）中選出符合各段意思的小標(biāo)題。
A.Get adequate iron
B. Keep yourself hydrated.
C. Get enough calories
D. A little exercise goes a long way.
E. Eat a balanced, varied diet
F. Spread your calories throughout the day.
The Energy Diet
How can I lose weight when every time I go on a diet, I'm so exhausted that I can barely make it through the day? So goes the complaint of many men and women who are concerned about being overweight. What many people don't realize is that a healthful weight-loss plan can actually boost your energy. The key is to eat smart. And then combine this healthful diet with some physical activity. Here are six pointers to get you started.
1.____
Consume too few calories and you'll have less energy, and decrease the amount of calories burned. "That's because one of the ways the body protects itself from starvation is to slow down its metabolism," explains Dr. Donald Hensrud, a nutrition professor at the Mayo Clinic, in Rochester, Minn. So how many calories do you need to feel energized while also slimming down? A healthful weight-loss rate is roughly one-and-a-half pounds per week, and the calorie intake to achieve this depends on your age, weight, and activity level.
2.____
The key to keeping your energy level up when you diet is to eat balanced meals that supply all the nutrients you need. "Vitamins and minerals act like spark plugs," explains Kristine Clark, director of sports nutrition at Pennsylvania State University. "They help release the energy in nutrient-rich food." Try to follow USDA guidelines. They call for 6 to 11 servings per day from the bread, cereal, rice, and pasta group; three to five servings of vegetables; two to four of fruits; two or three of milk or cheese; two or three of meat, fish, or eggs. Avoid fried and creamy dishes, and keep consumption of sweets and desserts to a minimum.
3____
When you go for five to six hours without food, the amount of fuel in your system starts to run low, and you begin to feel tired. Therefore, says Kristine Clark, it's important to eat at regular intervals to keep your energy up. If you exercise, it's important to make sure you have "fuel in the tank" before you head for the gym. Avoid eating a large number of calories at one time, since it's harder to control your total calorie intake, making weight gain more likely.
4____
About 10% of women of childbearing age in the United States are iron deficient. Iron is essential for energy and endurance because it is a vital component of red blood cells, which carry oxygen to working muscles. "Fatigue and listlessness can be directly associated with too little iron," says Frances Berg, a licensed nutritionist in Hettinger, N.D. The best sources of iron are meat, poultry, and some fish. Other sources: fortified cereals, dried beans, dried fruits, and peas.
5____
"I don't have the energy to exercise!" say many dieters. Indeed, a 1998 survey, developed in part by the Center for Sports Medicine at Penn State, found that over 70% of respondents cited "too tired" or "lack of energy" as key reasons to skip exercising. Yet exercise is exactly what these people need. And, lastly, don't try to do too much too soon. Consider breaking your exercise into small units. Instead of trying to do 30 minutes in one chunk, accumulate exercise in short bouts （一場，一回）every day by mowing the lawn, walking to work, or climbing stairs instead of taking an elevator. It won't be long before you reap （收獲）the rewards. Imagine carrying a 15-pound sack of groceries around all day. Then think about how much more energy you'd have if you put that sack down.

科目：高中英語 來源：2013屆浙江省杭州四中高三第九次教學(xué)質(zhì)檢英語試卷（帶解析） 題型：填空題

下面文章中有5處需要添加小標(biāo)題。請從以下選項(xiàng)（  A、B、  C、D、E和F）中選出符合各段意思的小標(biāo)題，并在答題紙上將相應(yīng)選項(xiàng)的標(biāo)號涂黑。選項(xiàng)中有一項(xiàng)是多余選項(xiàng)。

A. Find a fiction book.
B. Learn how to read your card.
C. Find your non-fiction book.
D. Decide if you want to search by author, title or subject.
E. Learn to find the card you need.
F. Understand the Dewey Decimal System.
 
The card catalog was once found in every library. Most libraries have now replaced the card catalog with a computerized cataloging system. However, some libraries still have the set of drawers with thousands of cards inside, and some library patrons still prefer the hands-on approach to researching the information they need. Cards are set up alphabetically in long drawers. Different types of cards are kept separate from each other so you may search by author, title or subject. Learning to use the card catalog can help you find the book you want without waiting for a computer terminal.
Instructions:
1______
Once you have found the card for the book you want, write down the numbers and letters at the top of the card and the title and author of the book. The numbers at the top are how the book is cataloged using the Dewey Decimal System, and the letters are the first three letters of the author's last name. Your library will have the numbers at the end of the stacks (the shelves of books), so find the stack your book is located in, then scan the shelves of that stack until you locate the number on the card. More than one book can have the same number, so you will narrow down your search if you have the first three letters of the author's name.
2______
The cards in a card catalog reference other cards. An author card will also have a book title and subject, a title card will have the author and subject, and a subject card will have author and title. This is handy for cross-referencing, so if you want to read a book on beekeeping, you can look that up in the subject cards and find an individual card on each book the library carries on beekeeping.
3______
If you want to look up a book by Stephen King, find the author cards in your library's card catalog, and look under "K". The cards are organized by last name and are broken down into the individual drawers. Sometimes a letter will take up more than one drawer, so you may find drawers that have "Ka-Ke" and then "Ki-Kr." Stephen King will be in the drawer with "Ki-Kr." You would find a card in a similar manner by title or by subject by finding the drawer with the corresponding letters such as "Be" for beekeeping in the subject cards or "Wr" for "The Writer's Market" ("The" is not considered part of titles).
4______
This isn't required to use the card catalog, but it can make searching for your book a little easier. The numbers range from 000 to 999; 000-099 are general subjects, 100-199 are psychology and philosophy, 200-299 is religion, 300-399 is social science, 400-499 is language, 500-599 are natural science and math, 600-699 is applied sciences, 700-799 is art, 800-899 are literature and plays, and 900-999 are geography and history.
5______
The author card will have a call number at the top, a line with the author's name with last name first, then lines for the title of the book, its publisher, a brief summary and subject listings. For an author with many books like Stephen King, there will be a card for each of his books in alphabetical order. Title cards are similar but have the title first, then the author in the following line. Subject cards have the subject in all capital letters at the very top of the card and the same information as on an author's card. Many cards on the same subject will be organized by the authors' last names.
