15．The CDs are on sale!Buy one and you get _____ completely free．（　　）

12．IN 2005，David J．Hand，a math professor at Imperial College London，went to a conference in the US with one of his students．They bought their return tickets separately．But when they boarded the plane，they were surprised to find that they were seated right next to each other．
"What a coincidence!"you might say．
Yes，coincidences happen all the time．Sometimes they are so weird （不可思议的） that there seem to be no explanations for them．That sometimes leads people to attribute them to supernatural forces．But are those really responsible？
According to a new book by Professor Hand，The Improbability Principle：Why Coincidences，Miracles，and Rare Events Happen Every Day，what we think of as extremely unlikely events actually happen around us all the time，and they can all be explained by the laws of probability，reported The Washington Post．
Take Hand's experience on the plane as an example．Since there are 450seats on that plane，it may seem like a 1in 450chance that he would have been seated next to his student．But the fact is that many passengers travel in pairs or other groups，and they all require adjacent （相邻的） seats，which makes solo travelers more likely to be seated next to other solo travelers．This increases the odds from 1in 450to a much greater chance．
Another occasion on which coincidences happen frequently is the lottery．On Sept 6，2009，for example，the Bulgarian lottery randomly selected the winning numbers 4，15，23，24，35，and four days later those numbers were chosen again．
According to Hand，although the odds of two specific number draws （抽取） matching are very small，since there are many lotteries globally，the chance of any two draws matching increases with the number of draws，and it reaches a probability of greater than 50percent by the 4，404th round．?
"With a large enough number of opportunities，any outrageous （不寻常的） thing is likely to happen，"writes Hand．
People tend to underestimate the probability of an event because they usually focus on specific instances instead of the broader context，he added．
"We should expect the unexpected，"Hand told New Scientist．"They may not be as improbable as you think．"

43．By mentioning Hand's experience on the flight at the beginning of the article，the author intends toD．
A．show how people usually react to coincidences
B．show that such coincidences actually happen frequently
C．promote Hand's newly-published book on coincidences
D．make us wonder what caused that coincidence
44．What does Hand think can explain almost all coincidences？B
A．Supernatural forces．
B．The laws of probability．
C．Their broader contexts．
D．The law of natural selection．
45．What did Hand believe increased his chances of sitting next to his student？C
A．The limited seats on the plane．
B．The times when they booked their return tickets．
C．The fact that many of the other passengers were traveling together with others．
D．The rule that solo travelers must sit in specific areas of planes．
46．What can we conclude from the article？C
A．The author believes that there are no supernatural forces at all．
B．If you bet on the same numbers each time，you will soon win the lottery．
C．Failing to see the broader contexts for events makes us fail to grasp their true probabilities．
D．Outrageous events wouldn't happen if there were a large enough total number of events．

19．Recently I failed an exam．However，when I came out of my teacher's office，I told myself，"Smile!It's not so serious．"
I smiled a big smile and it （61）worked（work） a little，really．
Everyone gets （62）disappionted（disappoint） sometimes．I used to be always influenced by pressure and I was often in low spirits．But one day I meet （63）with a sentence in the Bible，"Do not be anxious about tomorrow，for tomorrow will be anxious for itself，let the day's own trouble be enough for the day．"（64）Itsuddenly occurred to me that （65）worrying（worry） about a problem doesn't help．Why not just give a big smile and face up to the trouble？"
Now every time I want to cry，I remind myself that（66）laughter （laugh） is better than tears and anger．I （67）deeply（deep） believe that there's something magical about a smile．A smile helps me recover confidence and gives me （68）the courage to move on．
Remember，whenever you're faced with a setback，（69）whateverdifficulty you come across，all it takes is determination and you can feel happy again．Smile at life，（70）and it will shine on you．

8．The Streisand Effect
When Barbra Streisand discovered in 2003 that a photograph of her California beach house was among 12，000photos on the Internet as part of a collection by a photographer Kenneth Adelman，she did what any famous person would do：hit him with a﹩50million lawsuit （诉讼）．But in trying to hold back the images，she caused a different result．Her legal actions led to almost half a million people visiting the website，viewing and copying the photos within a month．
Ever since then，the effect of letting public know something you are trying to keep secret has been called the"Streisand effect"．The problem for anyone trying to cover up information is that the Internet is the world's biggest and most useful copying machine．Put a document （文件） on to a connected machine and it will spread．So when you want to be famous，you can't，but if you find yourself receiving too much attention and want to remove yourself，you cannot．
There are many examples of the Streisand effect．Nine-year-old Martha Payne created a simple blog，posting the meals her school served．She took a photo of what was hardly a satisfying meal by anyone's standards．With the photo，she added a comment，"Now Dad understands why I am hungry when I get home．"The thing did not go too far，until the local authority （权威机构） banned （禁止） little Martha from doing that again．Martha posted a final post called"Goodbye"，explaining everything．Once the media found this out，things went from bad to worse for the authority．Now the blog has more than 9.5million page views．Martha has even expanded her blog by including pictures of school meals taken by other kids from all over the world，like Germany and Japan．
We can find similar examples throughout history．Man has experienced the Streisand effect ever since the birth of mass communication．Why does it exist？Every time you are told not to see what's in the secret shiny box wrapped in gift paper，you're going to do everything in your power to do exactly that!Just realizing that knowing something about someone is harmful to their status，we will want to know that piece of information．This is exactly the human nature．This is what lawyers and authorities should be familiar with．Unfortunately，a few of them fail to understand it．

33．What speeded up the spread of Martha's story？B
A．Parents'reaction．B．The authority's order．
C．Martha's comment．D．Supporting from the school．
34．What is the last paragraph mainly about？A
A．The root of Streisand effect．B．The influence of Streisand effect．
C．People's reaction to Streisand effect．D．Historical examples of Streisand effect．
35．What can be inferred from the passage？C
A．Streisand effect does good to most famous people．
B．It's not a good idea to argue against authorities．
C．The ban on something may have opposite effect．
D．Turning to the law is a perfect way to get one out of trouble．
