Lots of people find it hard to get up in the morning and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resting your body clock{#blank#}1{#/blank#} Here is how to make one.

    ● {#blank#}2{#/blank#} In order to make a change, you need to decide why it's important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reason, tell your family or roommates about the change you want to make.

    ● Rethink mornings. Now that you know why you want to wake up, consider re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags.{#blank#}3{#/blank#}That's a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.

    ● Keep your sleep/wake schedule on weekends. If you're tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating on the weekends actually feeds into your sleepiness the following week, a recent study found. {#blank#}4{#/blank#}

    ● Keep a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you've tried a new method for a week, take a look at your record.{#blank#}5{#/blank#}If not, take another look at other methods you could try.

There are a number of steps you can take before making a final decision.{#blank#}2{#/blank#} If you enjoy marine life, for instance, you should consider a marine biology major. If you love star-gazing, consider becoming an astronomer.

    Next, consider the academic subjects in which you excel(优秀). If you're not strong in math you might be better off not choosing engineering. If you are good at English you might choose to become an author or a journalist.{#blank#}3{#/blank#}

    Once you've established a list of potential career fields, research them further to determine which college majors are most proper. Then you can get an idea for what courses you'll need to take.{#blank#}4{#/blank#}

    Radar is an electronic device that detects planes, ships, coastlines, landmarks, and even storm clouds. The name radar comes from the first letters of the words radio direction and ranging. As the human eye uses light waves to see, radar "sees" with radio waves. Without radar, planes could not land safely in bad weather and ships could not move safely in thick fog. {#blank#}1{#/blank#}

    In the 1800s it was discovered that radio waves could be reflected from objects. But scientists did not make great advances in radar research until the 1930s, when the world was threatened by war.{#blank#}2{#/blank#} It has been used widely in almost every conflict since then.

    Echoes make it possible for radar to work. When a beam of radio waves is sent out, it strikes on an object and returns an echo. This echo is picked up by radar and recorded on a screen similar to television screen. On the screen an observer sees a flash, or a blip, that shows the direction and distance of the object. {#blank#}3{#/blank#}

    Airport control towers use radar to guide planes in for safe landings. Almost all large ships depend on radar to prevent collisions with icebergs or other ships. {#blank#}4{#/blank#}Weather forecasters "see" the size, direction, and speed of storms on radar screens. Astronomers can even use radar to measure accurately the distance to the moon. Thus, the device has generated major advancements.

    {#blank#}5{#/blank#}Huge radar antennas have been installed all over the United States. They guard us against possible enemy attacks. We have ballistic—missiles (战略导弹)warning systems that can alert us to attacks when missiles are more than 1,000 miles away. Other radar systems warn us against enemy aircraft and even spying space satellites.

A. Police track speeders in radar-equipped cars.

B. These measurements are now highly accurate.

C. The device can be used in a wide range of fields.

D. It is therefore especially valuable to shippers and travelers.

E. During World War II many countries used radar effectively.

F. Today radar is used by commercial airliners and weather forecasters.

G. Strengthening national defense is one of radar's most important functions.

    I just counted how many foreign languages I've studied so far in my life and it's been twelve!

    I always follow my interests and find ways to put my language learning into things I'm already interested in. I like to read blogs(博客)in other languages.{#blank#}1{#/blank#}. For the most part, bloggers tend to write the same way they speak, so I don't have to worry much about adopting strange terms that are only used in writing.

    Movies are also a really good tool, especially if you can find subtitles in the language you're learning.{#blank#}2{#/blank#}, they will still keep your brain listening and reading in the same language. Music is another way to start listening to things in your new language. Personally, I'm so bad at understanding lyrics(歌词)even in English, so this one doesn't really work for me, but I have friends who learn a language through lyrics. Games are of course also an excellent way of studying a new language. A lot of language learning computer programs include games. I'm super competitive and if I play any of them, I can be hooked for hours.{#blank#}3{#/blank#}.

    When the initial excitement of learning a new language begins to fade, it can be hard to stick with it. The hardest bit for me is when I'm comfortable enough with a language to understand most things and make myself understood. I'm actually stuck at this stage in Norwegian.{#blank#}4{#/blank#}. Ideally I should sign up to take a big language exam. Each time I start getting self-satisfied, it's time to take a new course or sign up for online lessons, or take up some sort of challenge that will require me to level up my skills.

    {#blank#}5{#/blank#}. The best language class I've ever taken was my beginner's Russian course at university where my professor never used any English. It got to the point where I would kind of just forget about English while in Russian class, which helped me to really immerse myself in the Russian language and do a whole lot with the limited Russian I had.

A. That's really uncomfortable

B. Whatever languages they're translated into

C.I also try to think in the language I'm learning

D. It's time well spent if I'm learning the language

E. Computer games always make me feel worn out

F. Though they don't always exactly match what's being said

G.I found them the perfect learning tool because they're usually written in oral language

    Caregivers care for someone with an illness, injury or disability. Caregiving can be rewarding, but it can also be challenging. {#blank#}1{#/blank#} Women especially are at risk for the harmful health effects of caregiver stress. These health problems may include stress and anxiety. There are ways to manage caregiver stress.

    The first thing to do is learn ways to better help your loved one. {#blank#}2{#/blank#} To find these classes, ask your doctor or call your local Area Agency on Aging.

    Take time out to meditate（冥想）or reflect. Spending 10 to 20 minutes twice a day to "clear your head" can work wonders when you're feeling overburdened. Some caregivers learn meditation techniques from classes or books on the subject, while others simply take time out to quietly reflect. {#blank#}3{#/blank#}

    Exercising is another good way to help mind and body recover. It's one of the best-known techniques for reducing stress and keeping healthy. A quick walk several times each week gives you significant health benefits. {#blank#}4{#/blank#} Your library may offer exercise DVDs. Invite a friend over to join you. {#blank#}5{#/blank#} Nursing a garden, watching a favorite TV show, or reading an article that interests you. Your favorite hobby can help "center" you and remind you that you still have a life outside of caregiving. You must make some time－even for 10－to take care of yourself.

A. Stress from caregiving is common.

B. Try to do something you enjoy every day.

C. You'd better keep a journal of your thoughts and feelings.

D. Find caregiving resources in your community to help you.

E. Whichever way you choose, it's important that you focus on clearing your mind.

F. There are many good indoor choices, too, from walking in place to yoga or tai chi.

G. Some hospitals offer classes that can teach you how to care for someone with an injury or illness.

My first career had been related to audiology (听力学)—one that allowed me to work part time while tending my growing family. But when my children grew up and left home, I found myself longing to be outside, not in a soundproof room in the hospital.

    So I began attending classes at the local university, hoping that might lead me to a new career. {#blank#}1{#/blank#} "What gave you pleasure as a child?" the counselor (顾问) asked. I thought for a while before responding, "Playing outside in the woods." Our discussion eventually led to a second master's degree, this one in zoology, and the job as a naturalist at a state park. I was 44 years old. {#blank#}2{#/blank#}

    But as I climbed the career ladder, my time in the field disappeared. I was chained to a computer screen. In the back of my mind, the career counselor's question sounded again. "{#blank#}3{#/blank#}"

    Shortly thereafter, an opportunity presented itself: a 4-month field research project at a university in the Netherlands. I found that field research allowed me to play in the woods again, but with a new purpose.

    At the end of the project, I was invited to participate in the "sandwich" Ph.D. program, in which students do research in their home country while receiving support and instruction in the Netherlands. I was 60 years old. I didn't think that earning a Ph. D. would further my career. {#blank#}4{#/blank#}

    Still, my colleagues raised their eyebrows. "{#blank#}5{#/blank#}" they asked, "It is all about the journey," I responded.

A. What gave you pleasure as a child?

B. I also went to see a career counselor.

C. What do you intend to do with a Ph.D.?

D. But I wanted to follow my new passion.

E. But when it was no longer right, I changed direction.

F. Can you believe you're actually getting paid to have this much fun?

G. And I was delighted to once again experience the joy of being outdoors.
