As we all know, sleep is very important and necessary. I would love everyone to develop the following four habits to have better sleep without needing the alarm（闹钟）wake-up call.

    {#blank#}1{#/blank#}If you eat much food an hour before you go to bed, your body will hate you, because your body needs time to digest while you are still awake.

    {#blank#}2{#/blank#}When I hear on TV that people just need 30-minute exercise a week, I think that's wrong. Every person should get 30-minute exercise every day. When you exercise, your body uses energy and feels tired. You have to recover from the tiredness. {#blank#}3{#/blank#} The harder you exercise your body, the faster it falls to sleep and the better it sleeps.

    Turn the TV off. There are a few shows I still watch, but they will never get in my way of (妨碍) sleep. The bedroom is only for sleeping and rest. {#blank#}4{#/blank#}.

    {#blank#}5{#/blank#}A question to ask yourself: If I didn't have an alarm, what time would I get up? If that time is the time you need to get up, you should probably throw away the alarm. If the time you actually get up is much later than the time you need to get up, make great changes to your way of life and the time you go to sleep. No one should need an alarm.

A. Exercise for at least 30 minutes every day.

B. Don't eat any food 4 hours before you sleep.

C. Throw away the alarm.

D. Sleep is one of the most important things in our lives.

E. Your body recovers when you are sleeping.

F. Try to get up as early as you can.

G. Take the TV out of your bedroom.

    The holiday season isn't about shopping and gifts.{#blank#}1{#/blank#} However, holiday travel can be more expensive than gifts. Fortunately, the following tips will help keep your travel spending under control.

    Plan ahead. The earlier you book your travel, from airfare to hotels, the easier it is to find good deals.{#blank#}2{#/blank#} Your best prices on airfare come when you book three weeks before the plane leaves for domestic(国内的) flights. For international flights, consider booking 30 days in advance. Many experts point out that you should book travel between one month and three months out for high-traffic holidays.

    Book your air travel on cheaper days. Traveling by air on Tuesdays and Wednesdays often costs less than on Fridays and Sundays. During the holidays, it's not just about a specific day of the week. You also need to consider the days surrounding the holiday but days immediately before and after a holiday can be expensive. One of the best ways to save is to plan your air travel on the day of the holiday.{#blank#}3{#/blank#}

    Consider traveling overnight. Red-eye flights and overnight flights often cost less than those at more convenient times.{#blank#}4{#/blank#}  Traveling overnight can help you avoid a night in the hotel, as well as save your money on travel to your destination.

    {#blank#}5{#/blank#} You can't bring liquids with you on the airline, but you can bring sandwiches and other snacks. When you're on the road, you can buy food at local groceries to make your own meals, especially if you have access to（可使用） a microwave.

A. Bring your own food.

B. Consider affordable accommodations.

C. Traveling by plane is not the best choice.

D. Plus, booking earlier can save your money.

E. For instance, traveling on Christmas Day might be a great deal.

F. A great deal of travel also takes place during this time of year.

G. Other choices include sleeper trains as well as overnight ferries.

Should schools allow Halloween celebrations?

    Halloween is one of the most celebrated holidays in the United States. {#blank#}1{#/blank#} Many schools also celebrate the holiday by having kids dress up in costumes, take part in costume shows, and join in a variety of activities relating to Halloween. On October 31, the halls of schools across the country will be filled with princes, princesses, and superheroes. In addition to costumes, school Halloween celebrations often include classroom parties and trick-or-treating.

    {#blank#}2{#/blank#} They also say that dressing up in costumes allows kids to express themselves and show off their creativity.

    {#blank#}3{#/blank#} Officials at many of those schools say the celebrations are too time-consuming (费时的) and take away class time. They also point out that kids who can't afford costumes or who don't celebrate Halloween for cultural reasons feel left out. For example, Seth Boyden Elementary School in Maplewood, New Jersey, canceled（取消）its Halloween celebration last year. Officials at the school said that in the past, many students stayed home on that day.

    {#blank#}4{#/blank#} Bree Picower, a Professor of Early and Elementary Education at Montclair State, said, “Maplewood is a wonderful example of a school being responsive to society. Many schools plan to learn from it. Schools are places where students should feel included.”

    Parents in Maplewood had different opinions of this policy. Some said that the new no-Halloween policy was a welcome change. {#blank#}5{#/blank#}

A. It brings a lot of safety problems.

B. Experts say Maplewood is not alone.

C. Many people dislike these costumes.

D. Each year there're millions of Americans celebrations the holiday.

E. But more and more schools have canceled（取消）Halloween celebrations in recent years.

F. Many teachers, parents, and students see these celebrations as a fun break from the school day.

G. And others said that it was unfair that their children are now not allowed to celebrate Halloween in school.

    Choosing a major is a very important thing in our life. However, at the same time, it can be extremely challenging. So it's necessary to learn some simple tips that will make your decision much easier. {#blank#}1{#/blank#}. And how does that choice affect your future career? We can help guide you in choosing a major.

    Your major is your primary field of study in your undergraduate (大学的 ) program. It is the subject in which you earn your bachelor's degree. After completing a list of general education courses, you spend the rest of the time studying one subject of your choice. {#blank#}2{#/blank#}.

    For many students, it's best to try out different classes to figure out a major you'll like, but you need to have a couple of solid choices. {#blank#}3{#/blank#}, you should begin taking courses you are required to complete before graduation, so it will decrease your chances of needing to switch majors later because you already know what to expect.

    {#blank#}4{#/blank#}, you should begin thinking about how your field will lead to a job as soon as possible. Consider clubs, research programs and part-time jobs related to potential career choices for your major.

    For more career-specific majors like nursing and engineering, the majority of your studies will include skills that can be used in a future job. {#blank#}5{#/blank#}The sooner you begin working in a lab, on research projects or helping as a teaching assistant for a professor, the better you'II be able to figure out your career.

A. You have to think of ways to choose a major

B. Be sure that you choose a major that suits your interests

C. Once you have a better idea of which major you like best

D. While your major may or may not lead directly to a career

E. Do some research to find out which majors can help you get that job

F. Roughly one-third to one-half of your courses will be related to your major

G. However, you should still consider doing activities outside of the classroom to better prepare you

    Whoever wrote the song “it's the Most Wonderful Time of the Year” must have never experienced Holiday blues. Fortunately, psychological research suggests some effective ways you can beat the holiday blues. The key point is that sadness and other tough emotions are not what we should try to avoid. {#blank#}1{#/blank#}. Here are four strategies to help you make your own happiness recipe this holiday season.

    Don't force cheer

    At family gatherings with cousins you secretly can't stand, you tend to put on a happy face. Indeed, that might even seem like the most mature response—no drama, no conflict. But a 2011 study followed dozens of bus drivers, looking to see when they gave forced or honest smiles at their passengers. The results showed when the drivers pretended to have a good mood, their actual moods got worse. {#blank#}2{#/blank#}.

    Let off sadness

    The results of the bus-driver study can be explained by researchers, who find that negative feelings like sadness or anger only increase when we try to control them. {#blank#}3{#/blank#}. We don't like contradictory behavior.

    Respond cautiously

    Recently, scientists have been paying special attention to the benefits of caution. When you respond cautiously to an emotional trigger (e.g. overcooking the holiday turkey), you pause rather than reacting at once. {#blank#}4{#/blank#}. Besides, it is associated with less anxiety, and may even carry physiological benefits.

    {#blank#}5{#/blank#}.

    Of course, the holidays will bring a mix of highs and lows, but the most important lesson to keep in mind is that this variety of emotions might be the best thing possible for your overall well-being. In other words, sadness, anger, and other difficult emotions are nothing to fear. Just make sure you're balancing them with lighter experiences. And don't forget to give yourself a break.

A. Relax your mind

B. Enjoy a mix of emotions

C. We tend to deny the important function emotions serve

D. Instead, they can help contribute to a healthy and happy life

E. So trying to force happiness seems to have the opposite effects

F. A cautious response to a negative event reduces sadness we experience

G. We feel bad when our appearance contradicts how we truly feel inside

    Every animal sleeps, but the reason for this has remained foggy. When lab rats are not allowed to sleep, they die within a month. {#blank#}1{#/blank#}

    One idea is that sleep helps us strengthen new memories. {#blank#}2{#/blank#} 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. {#blank#}3{#/blank#}

    Now we have the most direct evidence yet that he is right. {#blank#}4{#/blank#}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 Tononi's theory is right, it would explain why, when we miss a night's, we find it harder the next day to concentrate and learn new information — our 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. {#blank#}5{#/blank#} "You keep what matters," Tononi says.

A. We should also try to sleep well the night before.

B. It's as if the brain is preserving its most important memories.

C. Similarly, when people go for a few days without sleeping, they get sick.

D. The processes take place to stop our brains becoming loaded with memories.

E. That's 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.

G. Tononi's team measured the size of these connections, or synapses, in the brains of 12 mice.
