Many teachers believe that the responsibilities for learning lie with the student. {#blank#}1{#/blank#} a long reading assignment is given, instructors expect students to be familiar with {#blank#}2{#/blank#} (inform) in the reading even if they do not discuss it in class or take an examination. The ideal student is considered to be one who is motivated to learn for the sake of learning, not the one interested only in getting high grades. Sometimes homework is returned {#blank#}3{#/blank#} brief written comments but without a grade. Even if a grade is not given, the student is {#blank#}4{#/blank#} (responsibility) for learning the material assigned. When research {#blank#}5{#/blank#} (assign), the professor expects the student to take it actively and to complete it with minimum guidance. It is the student's responsibility to find books, magazines, and articles in the library. Professors do not have the time to explain {#blank#}6{#/blank#} a university library works; they expect students, {#blank#}7{#/blank#} (especial) graduate students, to be able to exhaust the reference origins in the library. Professors will help students who need it, but prefer that their students should not be too dependent on them. In the United States, professors have many other duties {#blank#}8{#/blank#} teaching, such as administrative or research work. Therefore, the time {#blank#}9{#/blank#} a professor can spend with a student outside of class {#blank#}10{#/blank#} (limit). If a student has problems with classroom work, the student should either approach a professor during office hours or make an appointment.

    When I was a university student, I{#blank#}1{#/blank#}(attract) by the Chinese. So I got a job as a teacher in Wuhan three years ago.{#blank#}2{#/blank#} (think) back, I realize it was the students I. met in the first year and Chinese university life in general{#blank#}3{#/blank#}gave me the deepest impression.

    During my school days, I would rarely give up my spare time to any activity {#blank#}4{#/blank#}(connect) with study. Unless exams were approaching, my weekends were devoted to having fun or perhaps a part-time job. My Chinese students{#blank#}5{#/blank#}the other hand, seemed to spend their entire waking hours studying. I understand that competition in Chinese universities is extremely fierce. Nonetheless, their energy and motivation put{#blank#}6{#/blank#}(I) to shame.

    My first year in China was also my first year as a teacher. It was both challenging{#blank#}7{#/blank#}rewarding. One thing I know for certain is that my year in Wuhan changed me for the{#blank#}8{#/blank#}(good). Thanks to the{#blank#}9{#/blank#}(polite) and warmth of Chinese students, I overcame my fear of speaking in public and became more self-confident. Most{#blank#}10{#/blank#}(important), I met dozens of nice people and made many excellent friends.

    I love natural science, which came from my curiosity in nature. From {#blank#}1{#/blank#} early ago, I caught frogs and insects in the nearby woods. I explored the cool streams {#blank#}2{#/blank#} (run) through the woods and searched for fish living in the water.

    As I grew up, my interests expands around subjects in school, particularly {#blank#}3{#/blank#} biology, chemistry and physics in high school. These interests were increased with more time {#blank#}4{#/blank#} (spend) in the deserts of Arizona. The desert was not totally new to me, since I {#blank#}5{#/blank#} (visit) relatives in Phoenix several times before moving there. However, exploring the desert on my own was new. I checked under every rock and bush looking for {#blank#}6{#/blank#} (sign) of life. I found many incredible animals. Once I happened to discover {#blank#}7{#/blank#} (poison) snakes under a rock. I was very sacred. However, I {#blank#}8{#/blank#} (eventual) grew to be cautious of them and now snakes are my favorite study subject.

    I am now an ecologist. I have done research in deserts, forests, streams and lakes. Finding new species still {#blank#}9{#/blank#} (excite) me. I am glad to have a strong inquisitiveness (求知欲) in the natural world. My hobby and curiosity make me {#blank#}10{#/blank#} I am now.

    In 1850, an American lawyer, Bethune, bought a slave to work in his home. The slave, a woman, had a small child{#blank#}1{#/blank#}(call) Tom, who was blind.

    One day, Bethune {#blank#}2{#/blank#}(walk) around his garden when he heard music coming from the house. He went inside and found young Tom playing on the family piano. Bethune {#blank#}3{#/blank#}(immediate) realized that the boy, who was only four, had special abilities. He asked a band of {#blank#}4{#/blank#}(music) to come to the house and play in front of {#blank#}5{#/blank#} (he). Tom reproduced perfectly the music he had heard. Tom was indeed an unusual boy.

    In 1857, "Blind Tom" took part {#blank#}6{#/blank#} his first public performance. The reviews were so good {#blank#}7{#/blank#} Bethune took him on a tour of the US. Three years later, Blind Tom {#blank#}8{#/blank#} (invite) to the White House to perform for the president. Over the next forty years, Tom performed {#blank#}9{#/blank#}(enjoy) shows all over the US and other countries. His concerts were {#blank#}10{#/blank#} mixture of classical music and his own compositions.

    Not all memories are sweet. Some people spend all{#blank#}1{#/blank#}lives trying to forget bad experiences. Now American researchers are developing a pill,{#blank#}2{#/blank#}will help people forget bad memories. The pill is planned to be taken immediately after a{#blank#}3{#/blank#}(frighten) experience. They hope it might reduce, or possibly erase, the effect of painful memories.

    However, the new research has caused a lot of argument. Supporters say bad memories may ruin people's lives. They come back{#blank#}4{#/blank#}us when we don't want to have them in a daydream or nightmare(噩梦). They usually come with very painful feelings. The pill can help to reduce many{#blank#}5{#/blank#}(suffer). But those{#blank#}6{#/blank#}are against the research say that changing memories{#blank#}7{#/blank#}(be) very dangerous because memories show who we are.

    {#blank#}8{#/blank#}the drug could first be used in only very serious cases, some people even fear that it would become more commonly used. Don't forget people always have the ability{#blank#}9{#/blank#}(use) science for the wrong purpose. What we should do is help people to have{#blank#}10{#/blank#}(good) control of memories.
