4．Here is an astonishing and significant fact：Mental work alone can't make us tire．It sounds absurd．But a few years ago，scientists tried to find out how long the human brain could labor without reaching a stage of fatigue （疲劳）．To the amazement of these scientists，they discovered that blood passing through the brain，when it is active，shows no fatigue at all!If we took a drop of blood from a day laborer，we would find it full of fatigue toxins（毒素） and fatigue products．But if we took blood from the brain of an Albert Einstein，it would show no fatigue toxins at the end of the day．So far as the brain is concerned，it can work as well and swiftly at the end of eight or even twelve hours of effort as at the beginning．The brain is totally tireless．So what makes us tired？
Some scientists declare that most of our fatigue comes from our mental and emotional（情绪的） attitudes．One of England's most outstanding scientists，J．A．Hadfield，says，"The greater part of the fatigue from which we suffer is of mental origin．In fact，fatigue of purely physical origin is rare．"Dr．Brill，a famous American scientist，goes even further．He declares，"One hundred percent of the fatigue of sitting worker in good health is due to emotional problems．"
What kinds of emotions make sitting workers tired？Joy？Satisfaction？No!A feeling of being bored，anger，anxiety，tenseness，worry，a feeling of not being appreciated---those are the emotions that tire sitting workers．Hard work by itself seldom causes fatigue．We get tired because our emotions produce nervousness in the body．
29．What surprised the scientists a few years ago？C
A．Fatigue toxins could hardly be found in a laborer's blood．
B．Albert Einstein didn't feel worn out after a day's work．
C．The brain could work for many hours without fatigue．
D．A mental worker's blood was filled with fatigue toxins．
30．According to the author，which of the following can make sitting workers tired？B
A．Challenging mental work．
B．Unpleasant emotions．
C．Endless tasks．
D．Physical labor．
31．What's the author's attitude towards the scientists'idea？A
A．He agrees with them．
B．He doubts them．
C．He argues against them．
D．He hesitates to accept them．
32．We can infer from the passage that in order to stay energetic，sitting workers need toB．
A．have some good food．
B．enjoy their work
C．exercise regularly
D．discover fatigue toxins．
分析 本文是一篇说明文阅读，主要介绍了科学家们通过研究发现脑力劳动并不能使人劳累，使人感到劳累的是人的精神和情感状态，即厌烦、生气、焦急、紧张、忧虑以及不被欣赏等消极的情绪，这些情绪能在体内产生紧张感，使自己感觉到身体疲倦．
解答 29．C 细节理解题．根据第一段Here is an astonishing and significant fact：Mental work alone can't make us tire．可知脑力劳动时间长了并不会让人感觉到累，故选C．
30．B 细节理解题．根据最后一段A feeling of being bored，anger，anxiety，tenseness，worry，a feeling of not being appreciated---those are the emotions that tire sitting workers．可知厌烦、生气、焦虑、紧张还有不高兴的情感会使工人感到劳累，故选B．
31．A 态度判断题．根据第一段Here is an astonishing and significant fact：Mental work alone can't make us tire．We get tired because our emotions produce nervousness in the body．可知我们感觉到累是因为我们身体里产生了紧张的情绪，在这里可以看出作者是赞同这个观点的，故选A．
32．B 推理判断题．根据最后一段Hard work by itself seldom causes fatigue．We get tired because our emotions produce nervousness in the body．可知只要人们不觉得紧张，能享受生活，那么就能保持精力旺盛，而不会觉得累，故选B．

15．If You Get In，Make College CountAs tuition costs rise，with post-undergraduate （本科毕业后） jobs difficult to find，is higher education worth the cost？
Here is an unfortunate truth：For far too many incoming freshmen，college-any college-is not worth it．Year after year，students fail to get the full value of their tuition．
Many critics blame this cost/value problem on the universities，though each critic might point to a different reason：teachers always think of difficult research，the high costs of athletics，or the popularity of majors that are supposedly not suited to the new job market，to name some of their favorites．
But these are symptoms and not the illness itself．In our experience，the source of the wasted university experience begins with the student．Too often，students make bad choices or，frankly，just not enough great choices．
Too often we meet students who are so exhausted by the business of getting into college that they don't work hard once they arrive-one of the most common wastes of time and tuition．A poorly constructed transcript （成绩单） can be destructive to a student's education．Failure to engage and build professional working relationships with professors in office hours （which may lead to continued study，internships and more） also hurts the student's experience．
Another mistake is failing to make use of the many support networks on today's college campuses．It's almost embarrassing how many good offerings are rolled into each tuition dollar，but most students don't know they exist．
Another common point of failure is filling the schedule with too many extracurricular activities as students once did in high school，rather than getting intensely involved in one or two at most．The same can be said of overburdened course loads．
The final great failure we frequently see is the approach students （and their parents） take to selecting a major and accurately seeing its impact on a future career．University systems are not vocational schools．While critics nowadays complain about the attraction of useless majors-and some do exist-more frequently we see too many students pursue a course of study that is not their strength，simply because it seems to have obvious connections to a potential job after graduation．
Rather than perform poorly in a"practical"major and be of little interest as a future job candidate，we say it is better to major in a subject where a student would do well and master the tools of communication and analysis．Students who choose a unique major should complement （使更具有吸引力） that with some well-chosen skill courses，internships and other co-curricular activities that help with career opportunities after college．
So，is college worth it？It can be．Studies show that college graduates have many advantages-material，social and emotional-that can lead to greater success later in life．
To get the full value out of college，students must be as diligent and creative about getting out of college as they were about getting in．After all，the most beautiful，Olympic saltwater pool does you no good if you don't know how to swim．
