He does not accept statements which are not based on the most complete evidence available. He rejects authority as the only basis for truth. Scientists always check statements and make experiments carefully and objectively.
Furthermore, he does not readily accept his own idea, since he knows that man is the least reliable of scientific instruments and that a number of factors tend to disturb objective investigation.
Lastly, he is full of imagination since he often has to look for relationships in data which are not only complex but also frequently incomplete. Furthermore, he needs imagination if he wants to guess how processes work and how events take place.

The new studies show that fewer than half of the 9th graders in many of the nation’s largest cities, can ever graduate. The studies clearly show that the dropout rate isn’t dropping. And, in particular, the dropout rate isn’t dropping for poor and minority students.
Amazingly, though so many regret the rising dropout rate, our schools continue to lack formal plans--or any plans--to teach students motivation(动机). Most schools have no game plan to ensure that students understand that schooling will be completely necessary. Schools expect youth and children to act as though schooling is important, but they never teach them to believe that.
Years ago, families ensured that the children recognized the value of schooling. But in many modern families, the children may fail to recognize the importance of school life just because these families may actually tell their children that school is not important. Since many families are not motivating their children to be interested students, youth professionals, like teachers may need to provide this training. Otherwise, it is likely the dropout rate will continue not to drop, but only worsen.
Here are some strategies to convince even the most apathetic (无动于衷的) students that they must stay in school.
Ask students if they will ever need to work: The world has changed. 100 years ago, factory work was the booming job, and it required no education. Today, factories are increasingly automated. Most computer-related jobs require education and at least a high school diploma.
Ask students which century they will be prepared for: In 1900, the most common jobs were farm laborer and domestic servant—education not needed. Now, the most common jobs are office and sales staff—education and diploma usually needed. An amazing 6 out of 10 people today work in a store or office.
Ask students to devise a way that the employee could be replaced. For example, the coming trend in fast food is to use computers rather than people to run the restaurant. A prototype is apparently already being tested. The students should discover that most jobs that lack education and diploma requirements may be ripe for automation.
70. What does the underlined part mean in Paragraph1?
A. Few students can afford to go to school in large cities.
B. A large number of the 9th graders can graduate now.
C. There are still quite a few 9th graders leaving school early.
D. Most schools in large cities have fewer and fewer students.
71. Without the help of youth professionals,_____.
A. more and more families will gradually recognize the value of school.
B. it is likely that the dropout rate in schools won’t continue to drop.
C. some parents will be more convinced of their children’s future.
D. the schools will make proper plans to solve the problems with dropout.
72. The author takes factory work for example mainly to ______.
A. tell us that many jobs requires certain education in the past
B. show that there are more factory work and employment in modern society
C. show that employment in the computer field grows at a high rate
D. emphasize that modern jobs require education and schools are necessary
