9．College life can become a great struggle because students have to balance school，a social life，and sometimes a job as well．The following steps could help the grades of college students．
Go to class．Why did your parents pay for your tuition or why are your parents paying their taxes for financial aid？Even when you don't feel like attending class，just go．（51）CMany classes have in class assignments，pop quizzes，and case studies that only could be taken in class．If you are not there，you might lose points．
（52）A College is all about multitasking．Planners can really help you to balance homework，due dates and tests．You should try to get your work done early，then you will have less stress．
Be business-like about your education．If you had a job you would have to go to your job at 9 am and stay there until 5pm．（53）DIf you did the same thing in college，you would be great．Go to class，go to the library，study seriously，at 5 pm put away the books and go home．Once in a while you might have to work late，just like at a real job．
（54）FEveryone studies in different ways．Some can study with a lot of noise and others want silence．Some can't even study with music on and some need dead silence．Some like the library and some like to study with friends，or even outside．
（55）B

A．Stay organized．
B．Always try to keep a positive attitude and have confidence．

6．A woman was walking her dog along a beach in New Zealand in late June when she saw something that looked like a white ball in the sand．It turned out to be a young Emperor penguin that was lost．At his age，he should have been close to the Antarctic，swimming for fish and playing on the ice floes（冰川）．But this penguin started swimming north and just kept going．
The penguin attracted a lot of attention in New Zealand．It has been 40years since an Emperor penguin was last seen there．Researchers at the Department of Conservation were called in．They decided to watch the penguin closely，but not to disturb it in any way．Many New Zealanders came to Peka Beach to look at the elegant penguin．They were careful to keep their dogs away from it so it wouldn't be frightened．
The public nicknamed the animal Happy Feet．Researchers started to notice that Happy Feet didn't seem well．It turns out that he had been eating the sand from the beach，likely thinking it was snow．
The public raised more than 11，000pounds for an operation to get the sand out of his stomach．The operation was a success，and Happy Feet was taken to a zoo in Wellington，NZ．A group of experts met to decide how to help Happy Feet return to the wild．
Last Sunday，they put him on a boat called the Tangaroa，in a specially built ice-filled box and took him out into the Southern Ocean，southeast of New Zealand．There，they released him into the ocean，which is his natural habitat．He took one last look at his human helpers and then dived into the ocean．
"Emperor penguins spend their first five years at sea，"said Peter Simpson of New Zealand's Department of Conservation．"What happens now is up to the penguin．"
Happy Feet was fitted with a satellite transmitter（發(fā)射機）so they can monitor his progress using the Internet．So far，the trackers shows that he swam northeast for a little while before getting his bearings and heading south．

28．Where is the young penguin supposed to appear？B
A．On the sunny beach
B．Near the Antarctic．
C．Inside the hole in the ice．
D．In the depths of the ocean．

17．What are feelings for？Most nonscientists will find it a strange question．Feelings justify themselves．Emotions give meaning and depth to life．They exist without serving any other purposes．On the other hand，many evolutionary biologists acknowledge some emotions primarily for their survival function．For both animals and humans，fear motivates the avoidance of danger，love is necessary to care for the young，and anger prepares one to hold ground．But the fact that a behavior functions to serve survival need not mean that．Other scientists have regarded the same behavior as conditioning and learned responses．Certainly reflexes（反射） and fixed action patterns can occur without feeling or conscious thought．A baby seagull pecks（啄） at a red spot on the bill（喙） of its parent．The seagull parent feeds its baby when pecked on the bill and the baby gets fed．The interaction need have no emotional content．
At the same time，there is no reason why such actions cannot have emotional content．In mammals that have given birth including humans，milk is often released automatically when a new baby cries．This is not under intended control but it is reflex．Yet this does not mean that feeding a new baby is exclusively reflex and expresses no feeling like love．Humans have feelings about their behavior even if it is conditioned or reflexive．Yet since reflexes exist and conditioned behavior is widespread，measurable，and observable，most scientists try to explain animal behavior by using only these concepts．It is simpler．
Preferring to explain behavior in ways that fit science's methods most easily，scientists have refused to consider any causes for animal behavior other than reflexive and conditioned ones．Scientific orthodoxy （正統(tǒng)） holds that what cannot be readily measured or tested cannot exist，or is unworthy of serious attention．But emotional explanations for animal behavior need not be impossibly complex or unstable．They are just more difficult for the scientific method to check on in the usual ways，so cleverer and more skillful approaches are called for．Most branches of science are more willing to make successive evaluation of what may prove ultimately unknowable，rather than ignoring it altogether．

72．The example of the baby seagull pecking the parent's bill is used to support thatB．
A．it is an inborn ability for adults to look after the young
B．behaviors can be learned and involve no emotions
C．emotions are of great importance for survival
D．it takes time for animals to be conditioned
73．Which of the following can be learned from the passage？C
A．Breast-feeding a baby is conditioned or reflective but have no emotional connection．
B．Reflexes and conditioning will lead to a better understanding of animal emotions．
C．Scientists usually apply reflexes and conditioning in explaining animal behaviors．
D．Many evolutionary biologists believe that emotions are to some degree for survival．
74．To study animal emotions，scientists shouldC．
A．a(chǎn)nalyze human emotions
B．distinguish what is emotional
C．set up improved experiments
D．learn from animal behaviorists
75．What is the author's main purpose of writing this passage？A
A．To illustrate that emotions are worth our attention．
B．To compare human emotions with animal emotions．
C．To discuss the importance and usefulness of emotions．
D．To explain what reflexive and conditioned behaviors are．

4．Joan，super visor （檢查員） of the town's morals recently accused George，a local man，of having a drinking problem because she noticed his car outside the town's only bar．She reasoned，it was a logical assumption （邏輯假設(shè)）．George stared at her for a moment and said nothing．Later that evening，he parked his car in front of her house and left it there all night．
Why is it that so many of our logical assumptions are just plain wrong？And why do we want to act as if they must be true？In an age long before the Internet，a young American at a party found himself seated next to the famous Chinese diplomat Wellington Koo．Completely not knowing what to say to someone from such a different culture，this young man turned and asked，"Likee soupee？"After all，he assumed，don't all Chinese speak in broken English？Mr．Koo smiled and nodded．Later when called upon to speak，Wellington Koo delivered a wonderful talk in fluent English，sat down while the applause was still continuing，turned to the young man and whispered，"Likee speechee？"
Do you know why red roses are so popular？Men keep buying them．They assume that all women prefer red roses．But when women are asked what color of rose is their favorite，they are more likely to answer that they prefer yellow，white or peach．And when asked what kind of flowers they would prefer to receive，the answer is generally not roses at all．The age-old assumption that most women like red roses best is simply not true．
We all make assumptions．They're too often wrong and can easily get us into trouble．So here is what I've learned：when in doubt，check it out．And if I'm not in doubt，I still check it out．We may think we know．But what we know may not be so．So it's best to check it out．
64．According to the passage，we can know George isA
A．clever           B．honest        C．kind-hearted        D．bad-tempered
65．Wellington Koo's experience is mentioned to showB．
A．his talent in speaking English       
B．people's assumption can be false
C．the Chinese were looked down on      
D．his humor in doing with difficult situations
66．Red roses are so popular at the market in thatD．
A．women prefer red roses．                               
B．women like the red color best．
C．they smell pleasant than others．                      
D．men think women would like them．
67．How is this passage mainly developed？A
A．By giving examples．                  B．By presenting research results．
C．By analyzing causes．                 D．By making comparisons．

14．Music lessons in early childhood bring about changes in the brain that  could improve its performance far into adulthood，researchers say．
  Brain scans of young adults showed those who had formal musical training before seven had thicker brain areas dealing with hearing and self-awareness．
  The findings note how brain development can be influenced by the age when children start to learn a musical instrument，and how those changes can continue into later life．
"Early musical training benefits kids more than just making them enjoy music．It changes the brain，which could bring about cognitive advances as well，"said Yunxin Wang of Beijing Normal University．
"Our results suggest it's better to start musical training before seven，which agrees with what most piano teachers recommend，"she added．She hoped the results might help parents decide when was the best for their children to learn an instrument．
   The brain's cortex（皮層） plays a leading role in one's abilities，from thought and language to memory and attention．The area matures rapidly in the early years of life，and its development could be affected more if a person starts musical training before it fully matures．
   Wang studied 48 Chinese students aged between 19 and 21 who had received formal music training for at least a year sometime between the ages of 3 and 15．Each had a scan to measure the thickness of the brain's cortex．
   After considering sex and the number of years spent having music lessons，Wang found that musical training that started before seven appeared to thicken areas of the brain involved in language skills and executive function，which is a person's ability to plan and accomplish tasks．
"We're not sure why these changes occur，but a reasonable explanation is that early starters might depend more on hearing clues（線索） when learning music，since it might be more difficult for younger children to read music，"Wang said．
32．According to the researchers，musical training before the age of seven canA
A．contribute to future work．
B．create a successful life
C．develop all-round abilities        
D．deal with puzzling problem
33．When conducting the research with the students，WangD
A．tested their language abilities  
B．watched their musical performances
C．focused on school behavior and achievements
D．measured the thickness of the brain's cortex
34．It can be inferred from the last paragraph thatB．
A．it must be hard for kids to read music
B．kids are more likely to learn music by hearing
C．Wang's explanation has been the most reasonable
D．Wang will research into the reasons for the brain change
35．For what purpose does the author write the text？C
A．To describe the development of brain．
B．To challenge the previous discoveries．
C．To present the findings of the research．
D．To give advice on how to learn music．

1．The following are letters to the editor of a school newspaper
Dear editor，
I'd like to express my opinion about grades．Students should be allowed to study without worrying about grades．Fortunately，most educators are becoming aware of the fact that students have different interests and abilities．I understand that grades are useful，but grades often limit creativity．Competing for better grades causes many students to turn down opportunities to pursue music，dramatics and sports．Grades force an arbitrary（武斷的） standard of success on everyone．I do not demand as some extremists do，that grades be removed immediately．However，I do believe that less emphasis should be placed on grades．I hope that someday grades will become optional at Village High School．
Magdalena Smith
Drama Club
Dear editor，
I'd like to say something about grades．Let's face the facts about grades．Grades perform three basic functions．First，grades motivate students to work at their highest level of competence．Second，they act as a reward for hardworking students and as a punishment to students who do not work hard．Finally，grades are used as an effective standard by which to measure student achievement．Good grades help students to get jobs and to get into university．I've spoken with a number of students who have jobs，and most of them say that they were hired primarily on the basis of their grades．My grades helped me land a part-time job and will help me get into university next year．I think grades are extremely important at Village High School．

56．Which of the following is not Magdalena Smith's opinion？D
A．Students may give up the chance to learn music and sports for grades．
B．Students'creativity may not be developed for grades．
C．Grades should not be used to measure a person's success．
D．Grades should be taken away at once．

A．believes in the benefits of good grades
B．is concerned about students'creativity
C．doesn't work too hard at his studies
