19．We may all like to consider ourselves free spirits．But a study of the tracks left by 50，000mobile phone users over three months has finally proved that the truth is otherwise．
"We are all in one way or another boring，"says Albert-Laszlo Barabasi at the Center for Complex Network Research at Northeastern University in Boston，who co-wrote the study．"Spontaneous individuals are largely absent from the population，"
Barabasi and colleagues used three months'worth of data from a mobile phone network to track the mobile phone towers each person's phone connected to each hour of the day，showing their general location．They conclude that regardless of whether a person typically remains close to home or wanders far and wide，their movements are probably predictable as much as 93percent of the time．
Surprisingly，the mobile phone data showed that individuals'movements were more or less as predictable at weekends as on weekdays，suggesting that routine（日程） is rooted in human nature rather than being an effect of work patterns．
The mobile phone records were handled to make out the most visited locations for each user．Then the probability of finding a given user at his most visited locations at each hour through the day was calculated．
People were to be found in their most visited location for any given hour 70percent of the time．Not surprisingly，the figure increased at night，and decreased at lunchtime and in the early evening，when most people were returning home from work．
The team analyzed the randomness（隨意性） of people's traces to show it was possible in theory to predict the average person's places as much as 93percent of the time．
"Say your routine movement is from home to the coffee shop to work：if you are at home and then go to the coffee shop it's easy for me to predict that you are going to work，"says co-author Nicholas Blumm．
This predictability was not much affected by differences in age，gender，language spoken or whether a person lived in a rural or urban setting．

58．The"spontaneous individuals"are most probably people whoB．
A．a(chǎn)re boring in some way
B．a(chǎn)ct with much freedom
C．can live without a mobile phone
D．rely much on a mobile phone in life

A．which mobile phone network he is connected to
B．the content of his every phone call
C．which mobile phone tower he is connected to
D．how often he uses the phone every day
60．According to the sixth paragraph，a person is more likely toD at night than in the early evening．
A．return home from work
B．be found at home
C．take home as his most visited place
D．go to his most visited place
61．What is the passage mainly about？B
A．The factors that help determine one's routine．
B．The predictability of one's routine．
C．The influence of mobile phones on one's routine．
D．The new application of mobile phone．

9．Cell Phone Are the New Cigarette
When you get in your car，you reach for it．When you are at work，you take a break to have a moment alone with it．When you get in to a lift，you play with it．
Cigarette？Cup of coffee？No，it's the third most addictive thing in modern life，the cell phone．Experts say that it is becoming more difficult for many people to curb their longing to hug it more tightly than most of their personal relationships．
With its shiny surface and its smooth and satisfying touch，the cell phone connects us to the world even as it disconnects us from people three feet away．In just the past couple of years，the cell phone has challenged people in ways its inventors in the late 1940s never imagined．
The costs are becoming even more obvious，and I don't mean just the monthly bill．Dr．Chris Knippers，working at the Betty Ford Center in Southern California，reports that the overuse of cell phones has become a social problem not much different from other harmful addictions：a problem that limits one-on-one personal contact，and an escape from reality．
Sounds extreme，but we've all witnessed the evidence：the person at restaurant who talks on the phone through an entire meal，ignoring his kids around the table； the women who talks on the phone in the car，ignoring her husband； the teen who texts messages all the way home from school，avoiding contact with kids all around him．
 Is it just rude，or is it a kind of unhealthiness？And pardon me，but how is this improving the quality of life？
Jim Williams，an industrial sociologist based in Massachusetts，notes that cell-phone addiction is part of a set of symptoms in a widening gulf of personal separation．He points to a study by Duke University researchers that found one-quarter of Americans say they have no one to discuss their most important personal business with，Williams says studies show that we don't have as many friends as our parents．"Just as more information has led to less wisdom，more acquaintances via the Internet and cell phones have produced fewer friends．"he says．

60．Which orf the following best explains the title of the passage？C
A．More people prefer cigarettes to cell phones．
B．Cell phone users smoke less than they used to．
C．Cell phones have become as addictive as eigarettes．
D．Using cell phones is just as cool as smoking cigarettes．
61．The underlined word"curb"in Paragraph 2probably means"A"
A．contrlo B．ignore C．develop D．rescue
62．The example of a woman talking on the phone in the car supports the indea thatD
A．women use cell phones more often than men
B．talking on the phone while driving is dangerous
C．cell phones make one-on-one personal contact easy
D．cell phones do not necessarily bring people together．

7．What should you think about when trying to find your career？You are probably better at some school subjects than others．There may show strengths that you can use in your work．A boy who is good at mathematics can use that in an engineering career．A girl who spells well and likes English may be good at office work．So it is important to know the subjects you do well at school．On the other hand，you may not have any specially strong subjects but your records show a general satisfactory standard．Although not all subjects can be used directly in a job，they may have indirect value．A knowledge of history is not required for most jobs but if history is one of your good subjects，you will have learned to remember facts and details．This is an ability that can be useful in many jobs．
Your school may have taught you skills，such as typing or technical drawing，which you can use in your work．You may be good at metalwork or cookery and look for a job where you can improve these skills．If you have had a part-time job on Saturdays or in the summer，think what you gained from it．If nothing else，you may have learned how to get to work on time，to follow instructions and to get on with other workers．You may have learned to give correct changes in a shop，for example．Just as important，you may become interested in a particular industry or career you see from the inside in a part-time job．
Facing your weak points is also part of knowing yourself．You may be all thumbs when you handle tools； perhaps you are a poor speller or cannot add up a column of figures．It is better to face any weakness than to pretend they do not exist．Your school record，for instance，may not be too good，yet it is an important part of your background．You should not be apologetic about it，but instead recognize that you will have a chance of a fresh start at work．
62．What is the passage mainly about？A
A．Advice on choosing a career．
B．How to face one's weakness．
C．The significance of working hard at school．
D．The direct and indirect value of school work．

A．can help afford one's education
B．can help you prepare for future work
C．is a good way to practice the skills learnt in school

A．could restart his study in school
B．may also do well in his future work
C．will be regretful about the bad results he has got at school

8．One Monday morning，Paul and his classmates were in science laboratory for their practical chemistry lesson．The students were going to work in pairs to do an experiment．Before they began，the teacher gave them this description of the different stages of the experiment．
Stage 1：Prepare the equipment：a test tube，a crucible，a Bunsen burner and tongs．
Stage 2：Weigh 5grams of baking soda （sodium bicarbonate） and put it in a crucible．
Stage 3：Heat 10ml of hydrochloric acid （鹽酸） in a test tube．
Stage 4：Pour the warm acid onto the baking soda and continue to heat the mixture．
Result：The acid reacts with the bicarbonate（碳酸氫鹽）to form water，carbon dioxide gas and salt．The hotter the mixture，the quicker the reaction．Continue to heat the mixture until the water evaporates，leaving the salt in the crucible．
Paul and his partner followed the instructions and set up their equipment．Paul went to the cupboard to get a bottle of hydrochloric acid．He found that there was only one bottle in the cupboard so he took that．There was no label on the bottle and Paul didn't check with the teacher if it was the right solution．
He measured the liquid and poured it into a test tube．Using tongs to hold the test tube，he heated it over the Bunsen burner．That's when things started to go wrong．The liquid in the test tube was not hydrochloric acid．When it was heated，it formed a thick cloud of white gas．Soon the room was full of this strong smelling white gas．
All the students started coughing and their eyes hurt．The teacher immediately opened the windows and ordered the students to leave the laboratory at once．She realized that the liquid was a crylamide （丙烯酰胺） and that it is poisonous．
Fortunately，nobody was injured in the incident．However，it taught the students and the teacher a good lesson．

43．What lesson did the incident teach the students and the teacher？A
A．Never have a bottle without a label in the chemistry lab!
B．Obey your teacher's instructions in the Chemistry lab．
C．Acrylamide can't take the place of hydrochloric acid．
D．Finding something unusual happened，you have to leave the laboratory at once．
44．What substance were the students making in the experiment？C
A．Water              B．Carbon dioxide gas         
C．Salt               D．Poisonous gas
45．Why did Paul make the mistake？D
A．He went to the cupboard to get the bottle by himself．
B．He found that there was only one bottle in the cupboard so he took that．
C．There was no label on the bottle．
D．Paul didn't check with the teacher that it was the right solution．
46．Why did the teacher send the students out of the classroom？C
A．Because the room was full of this strong smelling white gas．
B．Because all the students started coughing and their eyes hurt．
C．Because the liquid was a crylamide and that it is poisonous．
D．Because someone was injured in the incident．
