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.

    Africa has been called the “dark continent” for a long time because {#blank#}1{#/blank#} lacks technology, electricity and other {#blank#}2{#/blank#} (achieve) of the modem world.

    Rhiannon Lambert, who treats about 180 clients a year with various kinds of eating disorders, says the number of those caused by "clean eating" {#blank#}1{#/blank#} (double) in the past three years. "They develop particular habits, or won't eat food when walking, because they think that food can only be eaten when they {#blank#}2{#/blank#} (seat)," she said.

    Clean eating is promoted by some food bloggers, who are increasingly thought by a number of medical experts to be having a bad influence on young people today. "Young people lose this and cannot afford the lifestyle needed to follow it," Lambert said. Health bloggers {#blank#}3{#/blank#} not have enough knowledge but offer dangerous advice. These people are now role models {#blank#}4{#/blank#} word will inspire young people. I have clients who think they have to be a strict vegetarian to be successful. The extreme form of this is known as orthorexia nervosa (健康食品强迫症).

    Ursula Philpot, a dietitian at the British Dietetic Association, said, "It is difficult to blame them completely. If it weren't the bloggers, then it could be {#blank#}5{#/blank#} else. Orthorexia affects more girls than boys, although boys are much more affected than girls." Philpot said, "At the top of most people's lists of bad foods includes gluten (麸质) and dairy. {#blank#}6{#/blank#} you talk to young people more, you will find some of them worry all day about eating a biscuit."

    The condition starts out as an attempt {#blank#}7{#/blank#} (eat) more healthily, but those who experience it fully focus on food quality and purity. "There may be several reasons for someone to take up clean eating," Philpot said. "Eating disorders are serious mental illnesses and their causes are complex. Research is telling us that they may be more biologically based than we thought, {#blank#}8{#/blank#} social and environmental factors also play a part in their development."

    Deanne Jade, the founder of the National Centre for Eating Disorders, said, "A lot of young people don't think they need treatment and there are too many messages in the media. What worries me is that a lot of people {#blank#}9{#/blank#} (promote) these ideas have no knowledge of nutrition. I don't know what the solution is, but in many cases, getting people to recover from an eating disorder means {#blank#}10{#/blank#} (get) them to relax their ideas about clean eating."

    Jane felt sweet in the drive－through line at Heav'nly Donuts. Just the day before, a stranger ahead of her in line had {#blank#}1{#/blank#} (generous) paid for her coffee. "The gesture made such a big difference in my day," says Eileen. She had recently lost her job as a doctor's {#blank#}2{#/blank#} (assist), and money was tight. But Eileen {#blank#}3{#/blank#} (inspire) to pay the $12 bill of the family in the car behind hers. {#blank#}4{#/blank#} she didn't know was that her kindness would set off a chain reaction. In two and a half hours, fifty-five drivers paid for the order of the person behind {#blank#}5{#/blank#} (they). The doughnut shop's employees {#blank#}6{#/blank#} (see) this before. This Heav'nly Donuts, in fact, is known as a special place, the customers of {#blank#}7{#/blank#} are considered as the "best in the world".
