经检验检疫机构预报检的出口货物，可直接向口岸检验检疫机构办理换证放行手续，无须提供任何单证。 ( )
参考答案：错
解析： 对出境货物进行预报检时应注意的事项：(1)出境预报检的样品应能代表报检的整批货物，检验检疫人员应按规定抽取代表性样品；(2)换证放行的时间。经预检合格的出口货物应在规定的检验检疫有效期内办理换证放行手续，超过检验检疫有效期的，庄重新实施检验检疫；(3)申请办理换证、放行手续时，应持《出境货物换证凭单》(正本)原件方可办理；(4)对预报检货物应做好批次管理。做到标记及批次清楚、堆放整齐、保管良好。故本题说法错误。
Passage Three
| For centuries, explorers have risked their lives venturing into the unknown for reasons that were to varying degrees economic and nationalistic (国家主义的). Columbus went west to look for better trade routes to the Orient and to promote the greater glory of Spain. Lewis and Clark journeyed into the American wilderness to find out what the U. S. had acquired when it purchased Louisiana, and the Appolo astronauts rocketed to 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 before. Today Mars looms (隐约出现) as humanity’s next great terra incognita (未探明之地). And with growing emphasis on international cooperation in large space ventures, it is clear that imperatives (需要，必要) other than profits or nationalism will have to compel human beings to leave their tracks on the planet’s 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 experiments provide insights profound enough to justify the expense of sending people across inter- planetary space With Mars the scientific stakes are arguably higher than they have ever been. The issue of whether life ever existed on the planet, and whether it persists to this day, has been highlighted by mounting evidence that the Red Planet once had abundant stable, liquid water and by the continuing controversy over suggestions that bacterial fossils rode to Earth on a meteorite (陨石) from Mars. A more conclusive answer about life on Mars, past or present, would give researchers invaluable data about 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 life in the universe. |
By saying "With Mars the scientific stakes are arguably higher than they have ever been" (Line 1, Para.4), the author means that______.
A．with Mars the risks involved are much greater than any previous space ventures
B．in the case of Mars, the rewards of scientific exploration can be very high
C．in the case of Mars, much more research funds are needed than ever before
D．with Mars, scientists argue, the fundamental interests of science are at issue
