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.

    Mr. Johnson lived in the woods with his wife and children. He owned {#blank#}1{#/blank#} farm, which looked almost abandoned. {#blank#}2{#/blank#} (lucky), he also had a cow which produced milk every day. He sold or exchanged some of the milk in the towns nearly for other food and made cheese and butter for the family with what {#blank#}3{#/blank#} (leave). The cow was their only means of support, in fact. One day, the cow was eating grass {#blank#}4{#/blank#} it began to rain heavily. While {#blank#}5{#/blank#} (make) great efforts to run away, she {#blank#}6{#/blank#} (fall) over the hill and died. Then the Johnson tried to make a living {#blank#}7{#/blank#} the cow. In order to support his family, Mr. Johnson began to plant herbs and vegetables. Since the plants took a while to grow, he started cutting down trees {#blank#}8{#/blank#} (sell) the wood. Thinking about his children's clothes, he started growing cotton too. When harvest came around, he was already selling herbs , vegetables and cotton in the market {#blank#}9{#/blank#} people from the town met regularly. Now it occurred to him that his farm had much potential and that the {#blank#}10{#/blank#} (die) of the cow was a bit of luck.

    The giant panda loves bamboo. An adult panda requires 12.5 kilograms of bamboo, which it{#blank#}1{#/blank#}(hungry) pulls out with its powerful paws, to satisfy its daily needs. Wild pandas live only in the high bamboo forests of Central China. These mountain forests are cool and wet--just as pandas like it. In the summer, they may climb as high as 4000 meters to help themselves to bamboo {#blank#}2{#/blank#}（grow) at higher altitudes. Frequently, pandas{#blank#}3{#/blank#}(see) eating in a relaxed sitting position, with their back legs stretched out before them.{#blank#}4{#/blank#} they may appear inactive, they are in fact skilled tree-climbers and efficient swimmers.

    Giant pandas are unsociable. They have a highly developed sense of smell that males use{#blank#}5{#/blank#}(avoid) each other and to find females for mating in the spring. After a five-month pregnancy, a female gives birth {#blank#}6{#/blank#} a cub. The blind baby pandas weigh only 142 grams and cannot crawl(爬行){#blank#}7{#/blank#} they reach three months of age{#blank#}8{#/blank#} are born white, and develop their much loved coloring later.

    There are only about 1000 giant pandas left in {#blank#}9{#/blank#} wild, with perhaps another 100 in zoos. Because they are so rare, much of{#blank#}10{#/blank#} we know about pandas comes from studying these zoo animals.

    Keep Your Eyes Open for Weight Loss Ads

    “In only six days I lost seven pounds of weight.”

    “Two full inches in the first three days!”

    These are the kinds of statements {#blank#}1{#/blank#} (use) in magazine, newspaper, radio and television ads, {#blank#}2{#/blank#} (promise) new shapes and new looks to those who buy the medicine or the device. The promoters of products say they {#blank#}3{#/blank#} shape the legs, slim the face and smooth wrinkles. Often such products are nothing more than money-making things for their promoters. The results they produce are questionable, and some are dangerous to health.

    To understand how these products can be legally promoted to the public, {#blank#}4{#/blank#} is necessary to understand something of the laws covering their regulation. If the product is a drug, FDA(Food and Drug Administration) can require proof that it is safe and effective before it {#blank#}5{#/blank#}(put) on the market. But if the product is a device, FDA has no authority {#blank#}6{#/blank#} (require) premarketing proof of safety or effectiveness. {#blank#}7{#/blank#} a product already on the market is a danger to health, FDA can request the producer or distributor to remove it from the market voluntarily, or it can take legal action, including seizure(查封) of the product.

    One notable case a few years ago {#blank#}8{#/blank#}(involve) an electrical device called the Relaxacisor, {#blank#}9{#/blank#} had been sold for reducing the waistline. The Relaxacisor produced electrical shocks to the body through contact pads. FDA took legal action against the distributor to stop the sale of the device on the grounds {#blank#}10{#/blank#} it was dangerous to health and life.

    People with colour blindness can't see colours in a normal way. Colour blindness{#blank#}1{#/blank#}(affect) approximately 1 in 12 men and 1 in 200 women in the world.

There are various causes of colour blindness. For the majority of colour-blind people, the condition is something they have from {#blank#}2{#/blank#}(bear), although some people get it later in life because of diseases.

    Most colour-blind people can see things as clearly as other people, but {#blank#}3{#/blank#} are unable to fully "see" red, green or blue light. There are different types of colour blindness and there are extremely rare cases {#blank#}4{#/blank#} people are unable to see any colour at all. The {#blank#}5{#/blank#}(common) form of colour blindness is red/green colour blindness. Although {#blank#}6{#/blank#} (know) as red/green colour blindness, the form of colour blindness doesn't mean sufferers {#blank#}7{#/blank#} (mere) mix up red and green. It means they mix up all {#blank#}8{#/blank#} (colour) that have some red or green as part of the whole colour.

    The effects{#blank#}9{#/blank#}colour blindness can be mild, moderate (中等的) or severe. Approximately 40% of colour blind people are even unaware that they're colour blind. Statistically{#blank#}10{#/blank#}(speak), most people with a moderate form of red/green colour blindness can only identify 5 coloured pencils from a standard box of 24 pencil crayons.
