Over forty percent of Americans worry about losing eyesight, but it's easy to include steps into our daily life to ensure healthy eyes. Here are five suggestions for a lifetime of healthy eyesight：

    Schedule（安排）yearly exams(检查). {#blank#}1{#/blank#} Experts advise parents to bring babies 6 to 12 months of age to the doctor for a careful check. The good news is that millions of children now can have yearly eye exams and following treatment, including eyeglasses.

    Reasons Why Physical Education is Important in School

    One of the best things you can do any time in the semester is go see the professor. So hoof on over to an office hour and have some one-on-one face time with someone who'll help you master the material and improve your grade, to boot. But how should you have this conversation with the professor? Here are five insider tips about how to make that office hour really count:

     {#blank#}1{#/blank#} No need to get all bent out of shape about going to see the professor. The professor would actually like to see you and answer your questions. Believe it or not, he or she is on your side and is eager to see you do well. And besides, he or she has seen many students stupider than you, so nothing you're gong to ask will set the record for stupidity.

    {#blank#}2{#/blank#} Even though you might feel more comfortable going with a friend or partner, the office hour will go better if it's just you and the professor. You'll get in more questions, the discussion will be tailored to what you need most help on, and two-party communication is almost always more productive than committee work. You friend can wait outside for the discussion.

     {#blank#}3{#/blank#} If you can't make the official office hours, most professors are willing to make individual, appointments to help you out. If you're lucky enough to land such an accommodation, though, be sure you're 100 percent on time. There's nothing that ticks off a professor more than making him-or herself available for a custom office hour only to find that you don't care enough to come on time. And besides, the professor might leave after ten minutes, which would make your trip a total loss.

    {#blank#}4{#/blank#} If you're meeting with the professor to go over a paper or test, or to ask questions about a particular lecture or reading, make sure you bring that paper or test, or your lecture notes or a copy of the article. The professor doesn't remember the comments he or she wrote on your individual piece of work—though he or she will be able to recall them after just a brief glance at your work. And if you have your lecture notes or the article in hand, you and the professor will be able to examine specific points that are confusing to you, rather than just talking in a general way about the contents.

    {#blank#}5{#/blank#} Office hours almost always go better if you bring a few specific questions to the meeting. It's almost never good to start a meeting with general comments such as: “I didn't understand what you said about [main topic of the course]”or “I couldn't understand any of your lectures last week.” Much better is to come in with two or three conversation-starters, about a specific concept, point, or problem you didn't understand. Keep in mind that in a fifteen-minute office hour (which is how long these things usually last), two or three questions are usually the most you'll have time to discuss.

    For hundreds of years, people have been wondering about the strange places that they seem to visit in their sleep{#blank#}1{#/blank#}However, they have been valued as necessary to a person's health and happiness. Historically people thought dreams contained messages from God. It was only in the twentieth century that people started to study dreams scientifically believing that they tell about a person's characte{#blank#}2{#/blank#}He believed that dreams allow a person to express fantasies or fears, which would be socially unacceptable in real life.

    The second theory to become popular was Carl Jung's compensation theory. Jung, a former student of Freud, said that the purpose of a dream is not to hide something, but rather to communicate it to the dreamer{#blank#}3{#/blank#}Thus, people who think too highly of themselves may dream about falling; those who think too little of themselves dream of being heroes.

    Using more recent research, William Domhoff from the University of California found that dreaming is a mental skill that needs time to develop in humans{#blank#}4{#/blank#}Until they reach age five, they cannot express very well what their dreams are about. Once people become adults, there is little or no change in their dreams. The dreams of men and women differ. For instance, the characters that appear in the dreams of men are often other men, and often involve physical aggression.

    The meaning of dreams continues to be difficult to understand{#blank#}5{#/blank#}If you dream that a loved one is going to die, do not panic. The dream may have meaning, but it does not mean that your loved one is going to die.

A. Dreams make up for what is lacking in waking life.

B. However, people should not take their dreams as reality.

C. They have been considered as meaningless nighttime journeys.

D. It gives scientists chances to better understand human mind.

E. Children do not dream as much as adults.

F. They think their mind is trying to tell them something.

G. First, there was Sigmund Freud's theory.

    You are changing. The universe around you is changing. Just because something was right for you in the past doesn't mean it still is. You realize there are deliberate(微妙的)changes you need to make to keep up with the changes happening around you and within you. {#blank#}1{#/blank#}

    Be yourself and fully control your life. {#blank#}2{#/blank#} You are in full control of your life so long as you claim it and own it. Because if you want to change, if you want to let go and move on with your life, you're the only person who can make it happen.

    Distance yourself for a while. Sometimes you need to take several steps back in order to become aware of a situation. {#blank#}3{#/blank#} Why? Because you can return to where you started and see things with a new set of eyes.

    Focus only on what can be changed. Realize that not everything in life is meant to be adjusted or perfectly understood. {#blank#}4{#/blank#} And if you can't change something you don't like, change the way you think about it.

    {#blank#}5{#/blank#} To let go is to be thankful for the experiences that made you laugh, made you cry, and helped you learn and grow. It's the acceptance of everything you have, everything you once had, and the possibilities that lie ahead.

A. Accept the truth and be thankful.

B. No one else is responsible for you.

C. It happens to you slowly as you grow.

D. Be faithful to what you always believe.

E. Focus carefully on what you can change.

F. Better take a break and explore something else for a while.

G. If you feel awkward, let's look at some ways to design the latter.
