       Sugar cane was once a wild grass that grew in New Guinea and was used by local people for roofing their houses and fencing their gardens. Gradually a different variety evolved which contained sucrose (蔗糖) and was chewed on for its sweet taste. Over time, sugar cane became a highly valuable commercial plant, grown throughout the world. (46)
       Sugar became a vital ingredient in all kinds of things, from confectionery (糖果点心) to medicine, and, as the demand for sugar grew, the industry became larger and more profitable.(47) Many crops withered (枯萎) and died, despite growers' attempts to save them,and there were fears that the health of the plant would continue to deteriorate.
       In the 1960s, scientists working in Barbodos looked for ways to make the commercial species stronger and more able to resist disease. They experimented with breeding programmes,mixing genes from the more delicate, commercial type. (48) This sugar cane is not yet ready to be sold commercially, but when this happens, it is expected to be incredible profitable for the industry.
       (49) Brazil, which produces one quarter of the world's sugar, has c~ordinated an international project under Professor Paulo Arrudo of the Universidade Estaudual de Campinas in Sao Paulo. Teams of experts have worked with him to discover more about which parts of the genetic structure of the plant are important for the production of sugar and its overall health.
       Despite all the research, however, we still do not fully understand how the genes in sugar cane. (50) This gene is particularly exciting because it makes the plant resistant to rust,a disease which probably originated in India, but is now capable of infecting sugar cane across the world. Scientist believes they will eventually be able to gro.w a plant which cannot be destroyed by rust.

A．Eventually, a commercial plant was developed which was 5 percent sweeter than before, but also much stronger and less likely to die from disease.
B．One major gene has been identified by Dr. Angelique D'Hont and her team in Montpelier, France.
C．Sugar cane is now much more vigorous and the supply of sugar is therefore more guaranteed.
D．Since the 1960s, scientists have been analyzing the mysteries of the sugar cane's genetic code.
E．The majority of the world's sugar now comes from this particular commercial species.
F．Unfortunately, however, the plant started to become weaker and more prone to disease.

       Many teachers believe that the responsibilities for learning lie with the student. If a long reading assignment is given, instructors expect students to be (51) with the information in the reading even if they do not discuss it in class or (52) an examination. The ideal student is (53) to be one who is motivated to learn for the sake of learning, not the one interested only in getting high (54) Sometimes homework is returned with brief written (55) but without a grade. Even if a grade is not given, the student is (56) for learning the material assigned. When research is (57) , the professor expects the student to take it actively and to complete it with minimum (58) It is the student's responsibility to fmd books, magazines, and articles in the library. Professors do not have the time to (59) explain how a university library works; they expect students particularly graduate students to exhaust the (60) sources in the library. Professors will help students who need it, (61) prefer that their students should not be too (62) on them. In the United States professors have many other (63) besides teaching, such as administrative or research work. Therefore, the time that a professor can spend (64) a student outside of class is limited. If a student has problems with classroom work, the student
should either (65) a professor during office hours or make an appointment.
