However, all living things still show the
25、【 C1】 _of aging, which will eventually result in death. Aging is not a disease, but as a person passes maturity, the cells of the body and the【 C2】 _they form do not function as well as they did in childhood and adolescence. The body provides less protection against disease and is more inclined【 C3】
26、 _accident. A number of related causes may contribute to aging. Some cells of the body have a fairly long life, but they are not【 C4】 _ when they die. As a person ages, the number of brain cells and muscle cells decreases. The other body cells die and are replaced by new cells. In an aging person th

Some of the protein chemicals in the cells are known 【 C8】 _with age and become less elastic. This is why the skin of old people wrinkles and

Some complex cell chemicals, such as DNA, store and pass on information that the cells need. Aging may affect this【 C10】 _ and change the information-carrying molecul

For each question, there are four suggested answers mark
30、ed A, B, C and D. Choose the one that you think is the best answer. 51 University teaching in the United Kingdom is very different at both undergraduate and graduate levels from that of many countries. An undergraduate course consists of a series of lectures, seminars and tutorials and, in science a
31、nd engineering, laboratory classes, which in total account for about 15 hours per week. Arts students may well find that their official contact with teachers is less than this average, while science and engineering students may expect to be timetabled for up to 20 hours per week. Students studying f
32、or a particular degree will take a series of lecture courses which run in parallel at a fixed time in each week and may last one academic term or the whole year. Associated with each lecture course are seminars, tutorials and laboratory classes which draw upon, analyze, illustrate or amplify the top
33、ics presented in the lectures. Lecture classes can vary in size from 20 to 200 although larger sized lectures tend to decrease as students progress into the second and third year and more options become available. Seminars and tutorials are on the whole much smaller than lecture classes and in some
34、departments can be on a one-to-one basis(that is, one member of staff to one student). Students are normally expected to prepare work in advance for seminars and tutorials and this can take the form of researching a topic for discussion, by writing essays or by solving problems. Lectures, seminars a
35、nd tutorials are all one hour in length, whilst laboratory classes usually last either 2 or 3 hours. Much emphasis is put on how to spend as much time if not more studying by themselves as being taught. In the UK it is still common for people to say that they are “reading“ for a degree! Each student
36、 has a tutor whom they can consult on any matter whether academic or personal. Although the tutor will help, motivation for study is expected to come from the student. 52 According to the passage, science and engineering courses seem to be more _ than arts courses. （ A） motivating （ B） varied （ C） d
37、emanding （ D） interesting 53 Which of the following is the length of lectures or seminars or tutorials? （ A） 1 hour. （ B） 2 hours. （ C） 3 hours. （ D） 15 hours. 54 In British universities, teaching and learning are carried out in_. （ A） a variety of ways （ B） laboratory classes （ C） seminars and tuto
38、rials （ D） lectures and tutorials 54 Who said the only way to learn about a country you cant visit is by reading a book? Dan Eckbergs television students at Hopkins High School know better. Theyre seeing countries and learning about cultures with the aid of electronic communications. Using computers
39、, satellite hookups, and telephone hotlines, Eckbergs students have already followed a team of cyclists 11,500 miles across the continent of Africa, sat atop Mount Kilimanjaro, and sweltered in the Sahara Desert. This winter theyll interact with an expedition exploring Central America in search of t
40、he classic Maya culture. You can join them. How? By following Eckberg and his class as they track the adventures of Dan and Steve Buettner, two world-class bicyclists from U.S.A. Starting last month, these two bicyclists, joined by archaeologists and a technical support team, are interacting with st
41、udents via the Internet, the worldwide computer network. From a classroom or home computer, students can make research proposals to the Buettners or the archaeologists at the various Central American locations theyve been exploring as part of their MayaQuest expedition. “We hope that someone will as
42、k a question that cant readily be answered,“ says Hopkins High School student Barry Anderson, “ and through the online activities, an answer will be found a discovery!“ Having students “discover“ why a civilization as advanced as the Maya collapsed in the 9th century is one key goal for the leaders
43、of the MayaQuest expedition. The more important goal is using interactive learning to discover the cause of the decline and compare it to issues we face today natural disasters, environmental degradation, and war. Ten lesson plans on topics ranging from the Maya language to the Maya creation myth ha
44、ve been developed for the interactive expedition. “Through a combination of live call-in television and the Internet,“ says Eckberg, “ were hoping to build excitement and engagement in learning in our school.“ 55 Dan Eckberg and his students learn about Africa by_. （ A） reading books （ B） watching v
45、ideo tapes （ C） interacting via the Internet （ D） cycling 11,500 miles 56 Which of the following activities is NOT involved in Dan Eckberg and his students expedition? （ A） Going to visit various Central American locations. （ B） Getting information through electronic communications. （ C） Discussing
46、different topics on the Maya civilization. （ D） Forming research proposals and discovering the answers. 56 Most earthquakes occur within the upper 15 miles of the earths surface. But earthquakes can and do occur at all depths to about 460 miles. Their number decreases as the depth increases. At abou
47、t 460 miles one earthquake occurs only every few years. Near the surface earthquakes may run as high as 100 in a month, but the yearly average does not vary much. In comparison with the total number of earthquakes each year, the number of disastrous earthquakes is very small. The extent of the disas
48、ter in an earthquake depends on many factors. If you carefully build a toy house with an Erector set, it will still stand no matter how much you shake the table. But if you build a toy house with a pack of cards, a slight shake of the table will make it fall. An earthquake in Agadir, Morocco, was not strong enough to be recorded on distant instruments, but it completely destroyed the city. Many stronger earthquakes have done comparatively little damage. If a building is well constructed and built on solid ground, it will resist an earthquake. Most d
