9．Even Spider-Man knew it，since Peter Parker's uncle Ben told him：With great power comes great responsibility．But when you're a fan of high-tech，the temptation to abuse your powers is hard to resist．
At first we place this equipment mostly in the interest of"family security"．For example，all of our external doors and windows are connected via a Vivint home security system．Nobody in our house carries keys anymore； instead，we open the WiFi-connected door locks with our own numerical codes．I get alerts to my phone when doors and windows are opened．Checking Vivint's website，I can see exactly who came or left，and when．
The Piper is just one of a handful of surveillance cams （監(jiān)控?cái)z像頭） we have set up across the house．Its purpose is not to scare the wandering teenagers； it's for chasing off intruders （people who goes into a place where they are not supposed to be）．But this surveillance equipment also doubles as an effective way to keep an eye on the kids．
In the old days，my parents used to hide in the dark so they could surprise my older sisters when they came carelessly home very early in the morning．Today there's an app （計(jì)算機(jī)應(yīng)用程序） for that．We have the ability to know where our children are and what they're doing，if we choose to．
Over the years we have installed various apps on their phones，like Life 360and Glympse，which let us look up their location with a few taps．Since my son began driving two years ago，we've had an Audiovox Car Connection dongle plugged into the onboard computer of our aging family car．I get a text whenever he leaves or arrives home，and if I so choose I can trace his recent movements on a map．And when my wife and I are out of town，we can call up cams on our phones to see if a teen dance party is being held in our household．
Still，the decision whether to track your loved ones is not an easy one．But I believe the positives finally outweigh the negatives．Technology has enabled us to fasten our kids with a rope at an earlier age，to allow them more self-direction，not less．It has helped us guide them，at a distance，toward making smarter choices．Hopefully it will also allow us to stay in touch with them when they get older and leave the nest．

55．According to the passage，what function does Vivint home security system have？B
A．Numerical keys．B．Warning service．C．Free WiFi．D．Website codes．
56．Why does the writer set up the Piper surveillance cam？C
A．To frighten away the people traveling around his house．
B．To keep an eye on his kids．
C．To force housebreakers to leave．
D．To see exactly who came or left，and when．
57．Which equipment does the writer use to know what his kids are doing？D
A．The  Audiovox Car Connection dongle．B．Glympse．
C．Life 360．D．The Piper surveillance cam．
58．What's the writer's attitude towards the high-tech equipment？A
A．Approving．B．Critical．C．Objectionable．D．Suspicious．

20．I'm afraid we have to accept the fact that criminals are getting younger all the time，but unfortunately the crimes are becoming more serious．I only wish we didn't have to admit this but，in doing so，we must first ask ourselves what's wrong with our society，or else our children clearly couldn't care less about law and order．
The days of the sneak thief who stole a couple of apples or a packet of sweets from a chain store are actually over．I had a chance to say this to a young offender the other day，"Sweets from a chain store？"He said，"You must be joking．That's what kids do．"I may add that he was aged 11．In other words，today's young criminals would find it laughable to risk being caught for petty theft of this description．They've got enough money in their pockets to buy the sweets they want，anyway．I think it's all too easy to put the blame on anyone but ourselves．
Faced as they are with a society that frequently gives them up on the grounds of color，race or low learning ability，these children turn to crime as a means of showing off their self-respect．Nurtured on films and TV glamorizing （美化） the role of the criminal，they are quick to copy these anti-heroes．It is a matter of increasing concern to the police and government that the Children and Young Persons Act，1969，is becoming improper to deal with the rise in young criminals．Because the emphasis has been placed on the cause and gentle treatment of their crimes，rather than on old-fashioned methods of punishment，the children themselves know well that there is very little that can be done to prevent them continuing to steal，damage and in some case even cause the death of those they choose to terrorize （恐嚇）．I don't like the look of this situation any more than you do．In our own interests and in those of our children and grandchildren，we cannot continue to take the"it's nothing to do with me"attitude we have used for so long．We must unite in a common demand for harder and stricter methods against these young criminals．
66．By raising the question"Sweets from the chain store？"，the writer was asking the boy whetherC
A．he wanted some sweets from a chain store
B．stealing sweets from a chain store was illegal
C．he was caught while stealing from a chain store
D．the days of stealing sweets from a chain store were over
67．Psychologically speaking，the reason why some youngsters commit crimes is thatB
A．they want to take revenge on society
B．they think it a way of showing their self-respect
C．they are good at imitating the criminals in the films
D．they don't know what they are doing is against the law
68．In dealing with young criminals，the writer is obviously in favor ofA．
A．severe punishment once used in the past
B．showing great concern about our children
C．more patient methods in educating young criminals
D．treating every young criminal as our own child
69．In the writer's opinion，who should be blamed most？D
A．TV and films．B．Young criminals．C．Police．D．Society．

17．Back in the 1860s，a British scientist named Henry Walter Bates noticed something interesting in the animal world：some harmless animals change the color or patterns of their skin to pretend to be deadly．For example，a kind of butterfly，Common Mormon，can change the pattern on its wings so that it looks like another butterfly species，the Common Rose，which is poisonous for birds to eat．
    Bates argued that animals develop this ability to protect themselves from being eaten．This theory had been widely accepted by scientists．But one question remains：how do these animals manage to do that？
    After more than 150 years，scientists are finally able to answer that question-it is all down to a gene called"doublesex"，according to a study published on March 6 in the journal Nature．
    In fact，scientists have long known that genes are responsible for this useful ability．Just like your hair color and the shape of your eyes are determined by your genes，the patterns on a butterfly's wings can be explained similarly．But until the new study，scientists hadn't been able to find out which genes in particular were responsible．
    Encouraged by the development of new technologies for studying genes，scientists at the University of Chicago，US decided to give it another try．They compared the genetic structure of the Common Mormons that changed their wing patterns with those of ones that did not．And all the results pointed to a single gene，"doublesex"．
This was much to the scientists'surprise．They used to expect that something as complex as this would be controlled by many different genes．For example，one gene would control the color of the upper part of the wing，one would do so for the lower part and one would control wing shape．
    However，the"doublesex"gene doesn't quite do everything by itself．Instead，it acts like a switch-it"tells"other genes to change the wing patterns．Isn't that clever？
    Scientists believe that this special ability of the"doublesex"gene was developed throughout the long history of evolution．"The harmless species gains an advantage by resembling something predators （捕食動(dòng)物） avoid，"Sean Carroll，a scientist at the University of Wisconsin-Madison，US told Nature．"It was obvious evidence for natural selection．"
63．What was newly discovered by scientists at the University of Chicago？D
A．Some animals can change their skin color．
B．Some butterflies can disguise themselves as other species．
C．Genes are responsible for the change in animals'skins．
D．Common Mormons change their skin patterns due to a certain gene．
64．What surprised scientists in the study？C
A．So many genes are involved in the change of patterns．
B．The genetic structure of the butterflies is so complex．
C．A single gene determines the change of patterns．
D．The gene"doublesex"singlehandedly changes the wing patterns．
65．Which of the following is the best title？B
A．A new discovery                  
B．How butterflies stay safe
C．A gene called"doublesex"
D．Natural selection．

4．When students arrive on campus with their parents，both parties often assume that the college will function in loco parentis（處在父母位置），watching over its young charges，providing assistance when needed．Colleges and universities present themselves as supportive learning communities-as extended families，in a way．And indeed，for many students they become a home away from home．Ideally，the college nurtures（養(yǎng)育）its students，guiding them toward adulthood．
Lifelong friendships are formed，teachers become guides，and the academic experience is enriched by social interaction．For some students，however，the picture is less beautiful．For a significant number，the challenges can become overwhelming（壓力過大）．
In reality，administrators at American colleges and universities are often forced to focus as much on the new generation of students．Public institutions in particular are often faced with tough choices about which student support services to fund．Private colleges are feeling the pinch（棘手）as well．Although tuition and fees can increase as much as 6.6percent in a single year，as they did in 2007，the high cost of doing business at public and private institutions means that students are not necessarily receiving more support in return for increased tuition and fees．To compound the problem，students may be reluctant to seek help even when they desperately need it．
Just as colleges are sometimes ill equipped to respond to the challenges being posed by today's students，students themselves are sometimes ill equipped to respond to the challenges posed by college life．Although they arrive on campus with high expectations，some students struggle with shyness or perfectionism，learning disabilities or eating disorders•Still others experience failed relationships； some suffer from acute loneliness，or mental illness．
Unfortunately，higher education is sometimes more of an information delivery system than a
responsive，collaborative（合作的）process．We have created cities of youth in which students can pass through unnoticed，their voices rarely heard，and their faces rarely seen．As class size grows in response to budget cuts，it becomes even less likely that troubled students，or even severely disturbed，will be noticed．When they are not，the results can be tragic．
As a teacher of creative writing who has worked with many overwhelmed students，I have found that there are ways to communicate more effectively．Most students have stories they want to share，and students in trouble can be desperate to find someone who will listen to them．Parents，as their children's primary listeners，have a key role to play．Some young people are unable to find their own way out of the dark，and a meaningful dialogue can become a light for them to see by．That is not to say that writing can be used to identify mental illness； rather，I think some of the approaches writing teachers use to enter into a reflective dialogue with students can be adopted by parents and students who want to learn more about each other．Having witnessed what can happen when a student communicates with himself，I believe this kind of responsive，one-on-one communication is more important than ever．Students in creative writing classes may have no idea that they have revealed so much about themselves because，for them，writing is like speaking inside the pages of a journal．In fact，all of us who write reveal more than we imagine．This is one of the reasons why writing，even more than speaking，can provide us with important insights into ourselves and others．
Many of us don't know our students as well as we should，yet it can be easier than we imagine to begin these necessary dialogues．

1．When a magazine for high school students asked its readers what life would be like in twenty years，they said：Machines would be run by solar power．Buildings would rotate（旋轉(zhuǎn)）so they could follow the sun to take maximum advantage of its light and heat．Walls would"give light"and"change color with the push of a button．"Food would be replaced by pills．School would be taught by electrical impulse（電脈沖）while we sleep．Cars would have radar（雷達(dá)）．Does this sound like the year 2000？Actually，this article was written in 1958and the question was，"what will life be like in 1978？
The future is much too important to simply guess about，the way the high school students did，so experts are regularly asked to predict accuately．By carefully studying the present，skilled businessmen，scientists，and politicians are supposedly able to figure out in advance what will happen．But can they？One expert on Cities wrote：Cities of the future would not be crowded，but would have space for farms and fields．People would travel to work in"airbuses"，large all-weather helicopters carrying up to 200passengers．When a person left the airbus station he could drive a coin-operated car equipped with radar．The radar equipment of cars would make traffic accidents"almost unheard of"．Does that sound familiar？If the expert had been accurate it would，because he was writing in 1957．His subject was"The city of 1982"．
If the professionals sometimes sound like high school students，it's probably because future study is still a new field．But economic forecasting，or predicting what the economy will do，has been around for a long time．It should be accuate，and generally it is．But there have been some big mistakes in the field，too．In early 1929，most forecasters saw an excellent future for the stock market．In October of that year，the stock market had its worst losses ever，ruining thousands of investors who had put their faith in financial foreseers．
One forecaster knew that predictions about the future would always be subject to significant error．In 1957，H．J．Rand of the Rad corporation was asked about the year 2000，"Only one thing is certain，"he answered．"Children born today will have reached the age of 43．"

C．the predictions about economic situation caused the investors to lose lots of money
D．good，accurate forecasting helped the stock market overcome the difficulties
