A microscope is a useful instrument for observing small objects. By producing a bigger image, the microscope reveals details that are undetectable to the naked eye(裸眼).
Before using the microscope, please read the instructions below.
CAUTION: Microscopes are both delicate and expensive and must be handled with care.
1. Always carry the microscope with two hands — one supporting the base and the other on the arm.
2. Avoid stretching the wire of the lamp across a walkway.
3. Keep the stage clean and always use a glass slide for specimens(樣本).
4. To avoid crushing the glass slide when focusing, begin with the lens close to the specimen and gradually back off to focus.
5. Keep the microscope covered to prevent the dust while it is being stored.
HOW TO USE THE MICROSCOPE:
1. Plug(接通電源) in the lamp.
2. Place a sample of what you wish to observe on a slide.
3. Adjust the mirror so it reflects light from the room up into the objective lens. When the mirror is correctly adjusted, a complete circle of light iwll appear when you look through the eyepiece.
4. Place your slide with the specimen directly over the center of the glass circle on teh stage. If it is a wet slide, be sure the bottom of the slide is dry.
5. With the LOW POWER objective leans placed over the slide, use the coarse focus knob to lower the lens to the lowest point.
6. Look through the eyepiece with one eye while closing the other eye. Slowly raise the lens until teh focus is relatively clear.
7. Use the fine focus knob to fine -tune(微調(diào))the focus.
8. Without changing the focus knobs, switch to the HIGH POWER objective lens. Once you have switched to HIGH POWER, use only the fine focus knob to make the image sharper.

Ever since humans lived on the earth, they have made v  1.    forms of communication. In general, the major form of expressing thoughts and feelings has been s_2.__ language. But when there is a language barrier(障礙), that is, people ­­­m 3.  each other , communication is completed through body language where gestures  r  4.   letters , words and ideas.

A growing aging population, along with increased access to health insurance，will create the need for about 52,000 more primary care doctors in the US by the year 2025, according to a new study.

The researchers want to estimate how many such doctors the US health care system would need after the passage of the Affordable Care Act (法令) in 2010, which will give an estimated 34 million more Americans access to health insurance.

But Dr. Winston Liaw, one of the study’s authors, said the biggest need will not come from the fact that more people have health insurance. “A lot of increase is going to be from population growth. That’s going to be the largest driver. Then, a smaller percentage is actually going to be from insurance expansion,” said Liaw, who was a fellow at Washington’s Robert Graham Center when the study was written.

Liaw and his workmates, who published their findings in the Annals of Family Medicine, use several databases to estimate how many primary care doctors there are in the US and how many people visit them. They then use that information with additional data from the United States Census Bureau to estimate how many doctors will be needed as the population grows, ages and gains more access to health insurance.

In 2008, the researchers estimated that people made 462 million office visits to primary care doctors. They estimate that the number will grow to 565 million by 2025. That additional use, they said, will require a 3 percent increase in the current primary care doctor workforce, or an additional 52,000 doctors or so. “That number is an expectation of how many we’ll need in addition to how many we have today,” said Liaw, now at Virginia Common-wealth University.

Of those, 33,000 doctors are needed to account for population growth, 10,000 for the aging population and more than 8,000 for increased insurance access.

“The fact that they made separate estimates of the increased demands for primary care services that might be due to population growth on the one hand, aging of the population and thirdly the Affordable Care Act is a very useful addition to this area, ” said Dr. John Rowe of the Columbia University Mailman School of Public Health in New York.

The study, however, cannot say whether or not there will be enough doctors to satisfy the additional need, said Liaw. For that ,he added, they would also have to look at how many people are expected to graduate from medical school and how many doctors will retire in his next studies.

A person may have a false idea about himself that will stop him from doing good work..
He may have the belief that he is unable to do it. A child may think he is  36  because he doesn’t understand how to make  37  use of his mental gifts. Old people may have a false idea that they are unable to learn new things because of their  38 .
A person who believes that he is stupid will not make a real  39  because he feels that it would be useless. He won’t go at a job with confidence necessary for  40 . Besides, he won’t work his hardest way, even though he may think he is doing so.  41 , he is likely to fail, and the failure will  42  his belief in his incompetence（無能）in turn.
Alfred Alder, a famous doctor, had  43  like this. When he was a small boy, he had a poor 44  in math. His teacher told his parents he had no ability in math in order that they would not  45  too much of him. In this way, his teacher and parents  46  the idea. He  47  their false judgment of his ability, feeling that it was useless to  48 . Then, he was very poor at math,  49  as they expected.
But one day everything changed. He worked out a problem which  50  of the other students had been able to solve. He  51  in solving the problem which gave him confidence. Soon he became especially good at  52 .

From his own experience, we can tell that if a person goes at a job with determination and purpose, he may  55  himself as well as others by his ability.

Years ago, a Southern woman was in one of my workshops. When asked to tell a story that  36 her character (品質(zhì)), she described an  37 when she was 5. She was at her grandfather’s house  38 up in a beautiful white skirt and new gloves ,   39 as she could be.
Her grandfather told her she could go into the  40 and get herself a cookie. Next to the cookies was a pile of coins. Sure that no one was  41 , she took one of the coins, too.
When she 42 with her cookie, her grandfather asked her to show him her  43 . She held out only her left hand  44 , and he said, “Show me the other hand.” When she unwillingly did  45 , showing the coin, she saw  46 in her grandfather’s eyes.
He paused a moment and then 47 her up, saying, “Darling, you can have anything in the world that I have, but it breaks my heart that you’d ever  48 it.” Some 50 years later, this story of how her grandfather gave her the gift of  49 still brought tears to her eyes.
Few things have as large an influence on  50 the values of a child as the strong pain of lovingly administered shame (羞愧). It helps judge right from wrong and gives a   51 emotional (感情的) dimension to moral (道德的) and character issues.
Kids, and adults for that matter, learn from their  52 . Parents, teachers and coworkers can remind them of their moral responsibilities without shaming or  53 them.
What we can’t do is just let  54 go, unless we want to send the message that’s okay. What we allow, we  55 . And we should never encourage anything other than moral excellence.
