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.

    Going online to do research when you're writing papers and doing projects is natural thing to do. {#blank#}1{#/blank#} Knowing how to evaluate and choose online resources can help you avoid headaches and wasting time.

    How can you make researching online as easy and effective as possible? Before you begin your research, make a list of the kinds of sites that are best for your topic. Is the website reliable and up to date? {#blank#}2{#/blank#}  Government sites ending in . gov and educational sites ending in .edu usually are safe bets. Established news-related sites are OK, too, but be sure that you're using the original source. If a newspaper article mentions another source, like an organization or website, go directly to that source to find the information.

    {#blank#}3{#/blank#}They can be good resources, but it's always best to check with your teacher to make sure he or she considers the site appropriate. Wikipedia. Org is popular and ranks highly in search results, but it can be edited by anyone, whether a person has accurate knowledge of the topic or not. {#blank#}4{#/blank#} 

    On commercial websites ending in .com, check to see if the site has advertising. {#blank#}5{#/blank#}And bogs, personal websites and social media sites are more likely to give personal opinions rather than facts.

A. Check to see if the author is identified and sources are given.

B. That's why it helps to know the best sites for your needs.

C. But all of the choices at your fingertips can seem overwhelming sometimes..

D. Sites ending in .org are usually run by non-profit organizations.

E. Many schools block access to images or websites that may be valuable to your research

F. At most schools, using Wikipedia as a source is not a good way to build credibility.

G. If it does, it may be biased(有偏见的), since it's trying to sell a product

    Variety is the spice of language. The words listed in this book are not intended to replace those that most people use most of the time. Rather, they are variations on the theme. We tend to use the same old words over and over again, to limit our powers of expression by limiting our vocabulary. {#blank#}1{#/blank#} but why not enhance your speech and writing by learning to use new ones from time to time ds alternatives?

    How often have you spoken of having an accident? {#blank#}2{#/blank#} Or why not occasionally describe a situation as aggravated（恶化）instead of worsened.

    I don't mean that you should throw away the Mold words”. {#blank#}3{#/blank#} English is an especially rich language, and often there are differences between two words that are generally regarded as die same. Thus, a mishap is not merely an accident; it is an unfortunate accident. Because there can be fortunate accidents, like bumping into an old friend you haven't seen for years and whose address you've lost. {#blank#}4{#/blank#}.

    No doubt a good many words in the list will be familiar to you, but do you use them, or do they remain the “property” of others? {#blank#}5{#/blank#}Try to make these words your own, as companions or friendly rivals of the ones you have owned in the past. Let them compete, and make your language all the richer.

A. Just vary them with the “new words”.

B. Many words have more than one meaning.

C. There is nothing wrong with the “old words”.

D. English words are grouped according to their origins.

E. Why not use the alternative mishap once in a while?

F. They are included to introduce variety into your speech and writing.

G. So in using mishap instead of accident, you must be sure of the difference.

    Someone in the U.S. is diagnosed with blood cancer every three minutes. And although about three in ten blood cancer patients can find a matching donor in their families, 70 percent of patients depend on a stranger to step in. That was enough for me to know I wanted to help.

    I registered online with Delete Blood Cancer. {#blank#}1{#/blank#}Four years later I got an e-mail from the organization and it said I had a possible match. To make sure all systems were a go, I had a couple of extra blood tests. I needed to donate bone marrow (骨髓).{#blank#}2{#/blank#}And my bone-marrow recipient was a little girl.

    Four months later, donation day arrived. At 9 a.m., the procedure started. By noon, I was already on my way home from the hospital. {#blank#}3{#/blank#}My legs were sore, like I had bruised my bone or something. The doctors said the pain would gradually disappear a few days later.

    {#blank#}4{#/blank#}The discomfort was secondary to the emotional high of helping a little girl with cancer. To me, it doesn't matter that I've never met the girl who received my bone marrow or that I don't even know her name. I still feel like I have such a powerful connection with her.{#blank#}5{#/blank#}

    A year later, I haven't heard how my bone-marrow recipient is doing, Delete Blood Cancer hasn't come back to me asking for another bone marrow donation, so I hope that's a good sign. But if they do call me back, whether it's for her or someone else, I'd do it again.

A. I won't lie—for a while, I was in pain.

B. I immediately broke down into tears on the phone.

C. There's something in our DNA that brought us together.

D. That's most often the case with young blood-cancer patients.

E. Even though the doctors gave me painkillers, I didn't try any.

F. I met with all of the doctors who would be performing the procedure.

G. Then my DNA was collected to see if I was a match for any patients in need.
