    Have you ever imagined the benefits that a good memory can bring to you? {#blank#}1{#/blank#} Here are four ways to improve your memory.

    {#blank#}2{#/blank#} There is evidence that sleep plays a vital role in the consolidation of memories relating to learning motor skills, such as learning to play a musical instrument or ride a bike. Having a full night's sleep soon after gaining a new skill helps consolidate the processes involved, so they can later be performed well.

    It's rewarding to continue education. Older people are often told to adopt a “use it or lose it” approach to maintaining cognitive (认知的) function. {#blank#}3{#/blank#} In a 2016 study, US researchers found participants aged 60-90 who spent 15 hours a week for three months learning a complex skill, such as digital photography, saw significant improvements in memory tests.

    Taking a break counts. {#blank#}4{#/blank#} More than a century ago, German scientists showed that people performed almost twice as well in memory tests if they took breaks.

It's useful to stay social. Having an active social life delays memory loss as we age, US scientists who asked people in their 50s and 60s to do memory tests every other year between 2001 and 2007 found the decline in recall abilities of their most sociable subjects to be half that of the least well connected. {#blank#}5{#/blank#}

A. Sleeping well helps strengthen memories.

B. Old people should participate in easy activities

C. Yoga, meditation or other relaxation techniques may help.

D. Memories can be destroyed if the brain doesn't have enough rests to sharpen them.

E. In fact, when it comes to memory, research suggests that only certain types of mental activities help.

F. Being able to remember important pieces of information can give you a powerful advantage in your life.

G. Having good friends, volunteering for charities and other forms of social engagement also protect memory.

    We know that choosing a college major can be very hard. But have no fear! Your choice of major will not lock you into a specific career for the rest of your life. Here's what you need to know about college majors before you commit.

    What is a major?

    {#blank#}1{#/blank#}Beyond general college requirements, you'll also take a group of courses in a subject of your choosing such as Chemistry, Literature, or Political Science.

    How important is my major?

    The major you choose will neither predict nor guarantee your future. Many graduates find jobs that have nothing to do with what they studied in college. If you intend to earn a professional degree after college, you will probably need certain courses. {#blank#}2{#/blank#}

    When do I declare a major?

    This varies widely across schools and programs. {#blank#}3{#/blank#}Others require that you declare upon a major by the time that you set foot inside your first class.

    {#blank#}4{#/blank#}

    Definitely. One of the most exciting aspects of college life is that it introduces you to new subjects and arouses new passions. However, keep this in mind. Every major has necessary coursework. If you change your major late in the game, it may take more than the traditional four years to earn a degree.

    What are minors and double majors?

    If one field of study doesn't satisfy your intellectual appetite, consider a minor. A minor is similar to a major in that it's an area of academic concentration. {#blank#}5{#/blank#}A double major provides you with an understanding of two academic fields. It allows you to become familiar with two sets of values and views while it also requires you to fulfill two sets of requirements.

A. Can I change my mind?

B. Is my major time-consuming?

C. It's your specialized area of study in college.

D. Most students find one major is more than enough.

E. Some schools may give you one year or more to decide.

F. But many future doctors major in non-science related fields.

G. The only difference is that it doesn't require as many classes.
