Did you know that if you need an alarm clock to wake up in the morning, you’re probably sleep-deprived （缺失）? __1._______ . On average, American teens get two hours less than the average 9.2 hours of sleep they need each night to function at their best.
There are many reasons why teens don’t get enough sleep. ____2.______ . When your parents were young, they might have read a book or watched television before trying to go to sleep. But today’s teens are likely to be surfing the Internet, texting, emailing, or playing video games right before bed. ___3._____ . And using them right before bed can result in difficulty getting to sleep. According to a survey by the National Sleep Foundation, teens with four or more electronic equipment in their rooms are much more likely than their peers to get an insufficient amount of sleep at night, and are almost twice as likely to fall asleep in school and while doing homework.
___4.______ . In the National Sleep Foundation survey, three-quarters of the teens took at least one drink with caffeine every day, and nearly one-third consumed two or more every day. With all the trendy “high-energy” drinks and coffees out there right now, it’s easy to get a caffeine overload and that’s not good for sleep.
So what can you do if you’re in lack of sleep? “The good news is that you only have to make up about a third of what you have lost, to function and feel better,” says Dr. Mahowald at a sleep disorders center. ____5.______ . But sleeping until noon on the weekend can cause problems — you’ll likely be wide-eyed until late those nights. Instead, try keeping a reasonable, regular sleeping and waking schedule.
A. One of them is a relatively new development.
B．Those extra two hours of sleep on Saturday and Sunday mornings can really help.
C．Most teens don’t get enough sleep.
D．Many teens also drink too much caffeine to sleep well.
E．Electronic devices are more exciting than simply watching television.
F．Researchers also have found that biology plays a role in teens’ sleep patterns.
G．Many school districts are shifting their start times to later morning for school students.

Taking a math test can be pretty stressful. Even if you know the material, you can still get the problem wrong. Knowing how to go through your math test and check your work can save you from handing in a test full of mistakes that can be avoided. 1.
Write it out
You can also check a math problem by writing everything out on paper. 2. Writing out math problems reduces your chances of missing anything to the lowest possible level, which is a common cause of incorrect answers.
3.
Make sure your answers work by doing the opposite procedure of what your problem calls for, including the answer you got the first time around. In other words, you would use the opposite of this addition problem—subtraction (减法)—to determine whether or not your answer is the correct one.
Plugging in
You may find that a variable isn’t good enough or have a problem where you have to solve for a variable (变量). 4. This is the only real way to assure yourself that the answer you’ve found is correct.
Check for a reasonable answer
5. For example, if you get an answer in the millions and you know it should be in the thousands, you’ve likely misplaced a point. Go back through the work on your paper to make sure all of your formulas and calculations are correct. If everything looks okay, do the problem again and compare the result of the second try to what you’ve got on the first try.
A. Do the opposite.
B. Correct the answers.
C. Plug the variable in the equation (方程) to check it out.
D. Therefore you’ll improve your grades, as well as your math skills.
E. It also helps you to figure out everything after you have already finished the test.
F. If the result of a problem seems to make no sense, it indicates that the answer is incorrect.
G. This helps you to know what information you have and what information you need to solve.

Most people know that chocolate is made from cocoa and that the origins of chocolate can be traced back to Central and South America. 1. But how did chocolate go from being the food of the gods to being the food of love?
2. They established the first cocoa plantation and used the cocoa beans as the main ingredient in a dark, bitter drink that we would call “chocolate”. The Mayas believed that chocolate had mystical properties. 3. In fact, cocoa beans were used as a form of currency that was worth its weight in gold.
Spanish conquistador Hernando Cortez was the first European explorer to realize cocoa’s commercial possibilities. 4. In 1529, Cortez returned Spain and introduced chocolate——as a drink mixed with sugar, vanilla, and cinnamon——to European society.
It caught on, especially with the nobility. As its popularity spread, people found new ways to make and use chocolate. 5. Whether it is in delectable desserts or crunchy candy, people all over the world are still in love with chocolate.
A. But cocoa also had commercial value.
B. But not all the people all over the world love cocoa.
C. For centuries, the native there regarded cocoa as a gift from the gods.
D. When he arrived in the New World in 1519, he soon established his own cocoa plantation.
E. Around A. D. 600, the Mayas were the main aboriginal group in Central America.
F. These days, chocolate is enjoyed as both a tasty treat and a romantic indulgence.

Everyone knows that the Frenchmen are romantic, the Italians are fashionable and the Germans are serious. Are these just stereotypes(刻板印象) or is there really such a thing as national character? And if there is, can it affect how a nation succeed or fail?
At least one group of people is certain that it can. A recent survey of the top 500 entrepreneurs (企业家) in the UK found that 70% felt that their efforts were not appreciated by the British public. Britain is hostile (敌意的) to success, they said. It has a culture of jealousy(嫉妒)．__1._ Jealousy is sometimes known as the “green-eyed monster” and the UK is its home.
Scientists at Warwich University in the UK recently tested this idea. They gathered a group of people together and gave each an imaginary amount of money. _ 2._ Those given a little were given the chance to destroy the large amount of money given to others— but at the cost of losing their own. Two thirds of the people tested agreed to do this.
_3.__ But there is also opposite evidence. The Organization for Economic Cooperation and Development recently reported that the UK is now the world's fourth largest economy. That is not bad for people who are supposed to hate success. People in the UK also work longer hours than anyone else in Europe. So the British people are not lazy, either.
“It is not really success that the British dislike,” says Carey Cooper, a professor of management at the University of Manchester Institute of Science and Technology. “It’s people using their success in a way that seems proud or unfair or which separates them from their roots.”
_4.__ They set out to do things in their way. They work long hours. By their own efforts they become millionaires.__ 5.__ It hardly seems worth following their example. If they were more friendly, people would like them more. And more people want to be like them.
A. This seems to prove that the entrepreneurs were right to complain.
B. The one who owns most money in the end is the winner.
C. As a result, the survey said, entrepreneurs were “unloved, unwanted and misunderstood.”
D. It is not true that British people are born jealous of others` success.
E. Some were given a little, others a great deal.
F. But instead of being happy they complain that nobody loves them.
G. Perhaps it is the entrepreneurs who are the problem.
