3．Parents who feel disappointed at their teenagers'failure to pay attention in class，and inability to sit quietly long enough to finish homework or plan ahead，should take solace．Their children are not being lazy or careless，according to new research．
    The research has found that teenagers'brains continue developing far longer into adulthood than we used to think．Teens may look like young adults but their brain structure is similar to that of much younger children．
"It is not always easy for teens to pay attention in class without letting their minds wander，or to ignore distractions from their younger brothers or sisters when trying to solve a maths   problem，"said Dr Iroise Dumon-theil．"But it's not the fault of teenagers that they can't pay attention and are easily distracted．It's to do with the structure of their brains．Teens simply can't think as well as an adult．"
    The research showed that the brain of a teenager works less effectively than that of an adult．"We knew that the front of the brain of teens functioned in a chaotic  （混亂的） way but we  didn't realize it continued until the late 20s or early 30s，"said Dr Sarah-Jayne Blakemore，who led the research．
    Chaotic thought patterns are a result of teenagers'brains containing too much grey matter-the cell bodies and connections which carry messages within the brain．As we age，the amount of grey matter in our brain reduces．
"What our research has shown is that there is simply too much going on in the brains of teens，"said Blakemore．"The result is that their brain energy and resources are wasted and their decision-making process is badly influenced．Adults，on the other hand，have less grey matter．This means that the brain works far more effectively．"
63．The underlined word"solace"in Paragraph 1 may meanC．
A．notice      B．medicine    C．comfort     D．a(chǎn)ction
64．When making decisions，A．
A．teens'brains continue to do much needless work
B．the grey matter in young children's front brain becomes active
C．people are not likely to be distracted until their late 30s
D．a(chǎn)dults are more independent than teens
65．What is the effect of having too much grey matter？D
A．It makes us always feel disappointed．
B．It makes us more intelligent．
C．It had a bad effect on the growth of teens．
D．It had a bad effect on decision-making．
66．What's the text mainly about？C
A．Teens have different brains from those of children．
B．Adults work more effectively than teens．
C．Grey matter makes teens unable to pay attention．
D．Brain energy is wasted in the brain's activity．

13．Life is to be enjoyed．There's no point in giving．up something you enjoy unless you get something back that's even better．When people eat more healthfully，exercise，and manage stress better，they find that they feel much better．The latest studies show that when you exercise and eat right：
YOUR BRAIN receives more blood flow and oxygen，so you become smarter，think more clearly，have more energy，and need less sleep．Some studies show that just walking for three hours per week for only three months is so helpful that it actually increases the size of people's brains!
YOUR FACE receives more blood flow，so your skin wrinkles（皺紋） less．You look younger and more attractive．However，an unhealthy diet，stress and smoking reduce blood flow to your face so you age more quickly．
YOUR TELOMERES （染色體端粒） get longer．Telomeres control how long we live．If telomeres become shorter，cells age more quickly，thus shortening your life．
Besides，one of the most interesting findings in the study was that the mothers'awareness of stress was very important．The researchers gave the women a questionnaire and asked them to describe how stressed they felt each day．The women who were aware that they were under heavy stress had shortened and damaged telomeres compared with those who felt more relaxed．On the contrary，some of the women who felt relaxed despite （盡管） raising a disabled child had more normal-appearing telomeres．In other words，if you feel stressed，you are stressed； if you feel fine，you are fine．
33．Which change will NOT happen to you when you exercise and eat right？C
A．Having fewer wrinkles．
B．Becoming cleverer．
C．Having shorter telomeres．
D．Looking younger．
34．From the last paragraph we learn thatD．
A．mothers will become more stressed if they raise a disabled child
B．mothers don't know how to handle stress effectively
C．many women knew little about educating children
D．mothers'positive attitudes are the key to managing their stress
35．The best title for the passage would beB．
A．Eat better，learn better
B．Feel better，live longer
C．Less stress，fewer diseases
D．Smoke more，age sooner．

14．It took an hour to clean and make the building safe．The homeowner plans to sue the robot's manufacturer．
In the United States，the lonely have Reddit and cats．In China，they have Singles'Day，which falls on Nov.11--11.11，the four ones symbolizing"bare branches，"Chinese slang for bachelors．Thought to have originated about 20 years ago as a joke on college campuses，Singles'Day was once an occasion for confessing one's feelings to that special someone．But since 2010，online retailers have transformed the holiday，also known as"Double 11，"into an epic online shopping extravaganza（盛會(huì)）alike to America's Cyber Monday．
Jack Ma，founder of Internet giant Alibaba，told Chinese Premier Li Keqiang late last month that Alibaba's sales on Singles'Day 2012 were"nearly 3.3billion"--morethandoubletheroughly1.5 billion purchased on Cyber Monday in 2012．For Singles'Day 2013，Ma expects sales to exceed 4.9billion．
The rise of singletons as a consumer group is not without its own costs．Chinese business magazine Caijing reported that big delivery companies were forced to scramble to find over 100 extra airplanes to handle the 323 million parcels they needed to deliver over the Singles'Day shopping period．
The holiday strains the logistics system：Products frequently sell out or arrive late．Even when everything moves smoothly，consumers complain about commercial gimmicks （花招）．According to the Beijing Evening News，a popular local paper，some online retailers quietly raise prices before slashing them．
Chinese are no strangers to loneliness：There are tens of millions of men in China who may never find love due to the country's massive gender imbalance，a result of the One Child Policy and a longstanding preference for male children．Chinese women don't have it easy either：Those who remain unmarried at the ripe old age of 27 risk being labeled"leftover women"．
Although poverty and singledom are often linked outcomes in China，at least one web user was sure of which was worse．"Spending Singles'Day alone isn't that scary，"he wrote．"What's scary is when you're so poor you can't even enjoy Taobao's‘Double 11．'"

B．It is celebrated every Monday by the Americans．
C．It is an online shopping day for the Americans．
D．It doubled the sales of Alibaba's on Singles'Day 2012．

61．What can we know from the last two paragraphs？B
A．Being poor means being single for a lifetime．
B．Many Chinese men are single because of gender imbalance．
C．Being single is even worse than being poor in China．
D．There are more singled female than singled male in China．
62．What can we conclude about Singles'Day from the text？C

11．An entire industry has been built upon the assumption that image is everything，but when it comes to it，an appealing image is not enough．If there is no substance（事實(shí)）behind the image，the product，service or person will fail eventually．
First of all，one should consider how important image is in the selling of products and services．Advertising agencies have raised the art of creating an image to a state of near perfection．Public concept of that product or service is certainly managed by the images created by the advertising agencies．But if the product or service does not live up to the image that was created，the customer will be very dissatisfied and possibly ask for their money back．For example，the Arthur Andersen accounting firm had spent decades building up an image of trustworthiness．But the recent scandal（丑聞）showed that behind that image，it cheated in business practices．Despite the previous positive image，the firm is being accused of criminal actions and it will probably not survive as a business unit．Although the image had been nearly perfect，the reality，behind the image has led to tile downfall of the word-famous accounting firm．
Similarly，personal advisers can build up a public image for politicians and movie stars．Putting out positive news releases，making sure that only the best photographs are published，and ensuring that the person is seen in all the right places can build up a very positive image in the view of the general commons．But once again，history is filled with examples of both politicians and movie stars that fell from grace like the story of the Hollywood actor giving in to the pressures of fame and fortune．With people，just as with products and services，image is certainly important，but without positive substance behind the image，failure is close．
To summarize，it is clear that an appealing image is extremely important to success，whether that image is related to selling a product or service or to the"selling"of a person．But image is only half of the equation（等式）．What lies behind that image is every bit as important as the image itself--the person or product must deliver truth on that image or there is little chance for long-term success．
67．The down fall of the Arthur Andersen accounting firm is due toB．
A．its previous images                 
B．its dishonesty in business
C．its bad management                
D．its poor service
68．Why did some famous people fall from grace？A
A．They failed to live up to their images．
B．Their images were not well built up．
C．They felt much pressure from the public．
D．They paid little attention to fame and fortune．
69．The structure of the passage isA．

70．The author tries to argue thatD．
A．image creates everything            
B．image is the key to success
C．truth is unlikely ever to be equaled    
D．truth and image are equally important．

Some animals，like the red-eyed tree frog，may scare enemies away with their color，Red-eyed tree frogs sleep during the day．If a meat-eating animal comes up to them and they open their eyes，the bright red color of their eyes might shock the animal long enough to give the red-eyed tree flog time to hop away to safety．

8．As the new term starts，freshmen around the world are asking the same question：how can I make the best of four years at college？The New York Times received suggestions recently from PhD students and seniors at some of the top universities．Here is their advice．
"Many young people today are raised in a protective cocoon（繭）"，wrote Tim Novikoff，a PhD student at Comell．"College is a time to explore the world beyond and a chance to learn new things about yourself．Take classes in different subjects．Try lots of different clubs and activities．"
Remember also to take some time away from campus，suggested Willie Lin，a student at Washington University．"If you spend all of your time in school，then it becomes too easy to let criticism from an unkind professor or a conflict with a roommate take up large proportions．"
Try to find work assisting a researcher or a professor---this is the advice from Aman Singh Gill，a PhD student at Stony Brook University．And he also said，"With a window into the world of research，you will find yourself thinking more critically，accepting fewer states at face value and perhaps developing a brave sense of what you can accomplish．"
Many young people can't imagine even a single day without devices such as computers and cell phones．But try to keep yourself off them，cautioned Christine Smallwood，a PhD student at Columbia University．
Start by scheduling a few Internet-free hours each day，with your phone turned off．It's the only way you'll be able to read anything serious．"This will also have the benefit of making you harder to reach，and thus more mysterious and fascinating to new friends and acquaintances（熟人），"she suggested．

63．The underlined sentence in Paragraph 3means we shouldB．
A．spend more time at school
B．take some time out of school
C．listen to criticism more

64．Who thinks it is important to consider something critically？A
A．Aman Singh Gill     B．Christine Smallwood
C．Tim Novikoff        D．Willlie Lin
65．As for modern information devices，the last two paragraphs mean to tell usC．
A．to keep ourselves off them forever not to use them
B．to turn them off
C．to make a schedule to use them
D．not to use them
66．This passage is mainly aboutA．
A．tips from some students for college life

12．It is reasonable to say that every teenager can be affected by peer pressure （從眾心理） at some point．Every day，in any high school，peer pressure has a major influence over the behavior of teenagers．It can be as subtle （微妙的） as being persuaded to be late for class or as extreme as a dangerous drug．Whether subtle or extreme，peer pressure can have damaging，sometimes life changing，and even serious results．
"Teens don't often consider the long-term results that some behavior can cause，"said Terri Price，a researcher．"Peer pressure can be very difficult to handle for many teens because of their fears of not fitting in"．Peer pressure has always been part of teen life，but teens experienceitdifferently than their former generations did in the past．Sources of peer pressure have increased because of the Internet and other electronic communications．
Recognizing peer pressure can be as simple as noticing that you have been asked to do something that you are not comfortable with．"Listen to your instinct （直覺），which is a sign for whether something is right or wrong．If it feels wrong，then most likely it is．"says Price．
Teens are in a time of life when they are still discovering who they are．Many teens are influenced by peer pressure because of their insecurities （不安全感）．This ca n make them helpless especially when their self-control is weak or they lack healthy support，causing them to take risky behavior or turn to unhealthy support．

13．US scientists have performed an important reversal（逆轉(zhuǎn)） of the ageing process in animal studies．They used a chemical to rejuvenate（使年輕） muscle in mice and said it was the equivalent（等同于） of transforming a 60-year-old's muscle to that of a 20-year-old-but muscle strength did not improve．Their study，in the journal Cell，identified an entirely new mechanism（原理） of ageing and then reversed it．Other researchers said it was an"exciting finding"．
Ageing is considered a one-way street，but now researchers at Harvard Medical School have shown that some aspects can be reversed．Their research focused on a chemical called NAD．Its levels naturally drop in all cells of the body with age．The team showed this damaged the function of the cell's in-built power-stations，leading to lower energy production and ageing．
Experiments showed that increasing NAD levels，by giving mice a chemical which they naturally change into NAD，could reverse the sands of time．One week of youth-medication in two-year-old mice meant their muscles became similar to those of a six-month-old．
Dr Ana Gomes，from the department of genetics at Harvard Medical School，said："We believe this is quite an important finding．"She argues muscle strength may return with a longer course of treatment．However，this could never be a cure-all for ageing．Other aspects such as shortening of telomeres or damage to DNA would not be reversed．
Dr Gomes told the BBC："Ageing is multi-factorial，it's not just one component（成分） we can fix，so it's hard to target the whole thing．I believe there is a lot of cross-talk in cells and energy is very important in a cell and likely to be a very big component of ageing that might cause some of the other things that happen with ageing．"
68．From paragraph 1 we learn thatD．
A．bones can be transformed
B．muscle strength can be transformed
C．color can be transformed
D．muscle can be transformed
69．From paragraph 2 and paragraph 3 we learn thatC
A．researchers think ageing is a one-way street．
B．NAD levels'dropping could make mice become younger．
C．increasing NAD levels could make mice become younger．
D．researchers think any aspect can be reversed．
70．Dr Gomes will agree thatB
A．we can target everything about ageing．
B．muscle strength may return over a longer course of treatment．
C．a(chǎn)geing could be cured．
D．energy is of little importance in a cell．
