20、egrees economic and nationalistic. Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain.

21、o the moon in a dramatic show of technological muscle during the cold war.Although their missions blended commercial and political-military imperatives, the explorers involved all accomplished some significant science simply by going where no scientists had gone.Today Mars looms as humanitys next gr

22、eat terra incognita. And with doubtful prospects for a short- term financial return, with the cold war a rapidly fading memory and amid a growing emphasis on international cooperation in large space ventures, it is-clear that imperatives other than profits or nationalism will have to compel human be

23、ings to leave their tracks on the planets reddish surface. Could it be that science. which has long played a minor role in exploration, is at last destined to take a leading role? The question naturally invites a couple of others: Are there experiments that only humans could do on Mars? Could those

The issue of whether life ever existed on the planet, and whether it persists to this day, has been hig

25、hlighted by mounting evidence that the Red Planet had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data a

26、bout the range of conditions under which a planet can generate the complex chemistry that leads to life, If it could be established that life arose independently on Mars and Earth, the finding would provide the first concrete clues in one of the deepest mysteries in all of science: the prevalence of

27、 life in the universe.（分数：5.00）(1).According to the passage, the chief purpose of explorers in going to unknown places in the past was _.

33、ed each year. At a speed of only 30 miles per hour it is the same as falling from a thirdfloor building. Wearing a seat belt saves lives: it reduces your chance of death or serious injury by more than a half.Therefore drivers or front seat passengers over 14 in most vehicles must wear a seat belt. I

34、f you do not, you will be fined up to 50. It will not be up to the drivers to make sure you wear your belt. But it will be the drivers responsibility to make sure that children under 14 do not ride in the front unless they are wearing a seat belt of some kind.However, when youre reversing your car,

35、you do not have to wear a seat belt; or when you are making a local delivery or collection using a special vehicle; or if you have a valid medical certificate which excuses you from wearing it.

41、t of us have noticed how important physical setting is to efficiency and comfort when we work. Todays corporations hire human engineering specialists and spend a great deal of time and money to make sure that the physical environments of buildings are fit to the activities of their inhabitants.Simil

42、arly, college classroom space should be designed to encourage the activity of critical thinking. We will move into the twenty-first century, but step into almost any college classroom and you will step back in time at least a hundred years. Desks are normally in straight rows, so students can clearl

43、y see the teacher but not all their classmates. The assumption behind such an arrangement is obvious: everything important comes from the teacher.With a little imagination and effort, unless desks are fixed to the floor, the teacher can correct this situation and create space that encourages interch

44、anges among students. In small or standard- sized classes, chairs, desks and tables can be arranged in different ways:circles, U-shapes, or semicircles. The primary goal should be for everyone to be able to see everyone else. Larger classes, particularly those held in lecture halls, unfortunately, a

45、llow much less flexibility.Arrangement of the classroom should also make it easy to divide students into small groups for discussion or problem-solving exercises. Small classes with moveable desks and tables present no problem. Even in large lecture halls, it is possible for students to turn around

46、and form groups of four to six. Breaking a class into small groups provides more opportunities for students to interact with each other, think out hard, and see how other students thinking processes operate all these are the most important elements in developing new modes of critical thinking.In courses that regularly use a small group format, students might be asked to stay in the same small groups throughout the course. A colleague of mine allows students to move around during the first two weeks,
