9．Facebook Is a Big Waster
During the first decade of the 21^st century，a popular and new word has come into our vocabulary-Facebook．This is the most popular social networking website on the Internet．（71）GYou can send messages to your friend's electronic wall，put up a status saying something like"Going to the mall，I need to get a new pair of shoes"or"it's finally the weekend!：）"．
In spite of the benefit it does on common people，it is true that this social network is a big waster．There are about 350million active users on this website and 67% of them are between the ages of 13-25．More than 35million users update their status every day．（72）A
The highest age group who use Facebook are teenagers．Most of them keep the website running whenever they are using the computer，if they aren't in school or when they aren't asleep．Facebook is just changing the new generation of youngsters unconsciously．The teenage life is one of the most important stages of life，（73）BIt is a distraction to their mind as well．Nowadays，when all their homework and research are on ICT（信息技术）they would easily switch to Facebook just to check if there was anything updated among their friends．
Facebook is also where people can see the gossip among their friends，virtual arguments，relationship status and updates，who is in whose"top friends"，you can become fan of anything，join groups，post pictures and videos，play childish games，invite friends to parties or events and a lot more．Generally，all these would just disturb people into living life to the fullest．It's not just teens who become addicted，even grown-ups do．An average person spends about 55minutes on Facebook．（74）CTechnology might be taking over people's life．Furthermore，people who use Facebook through their mobile phones are 50% more active on Facebook than non-mobile phone users．This shows people using Facebook on their phones as well as computers just can't stand being away from the website．Facebook is like crack to some folk．
（75）DThis would make them think how life is like without saying what's on their mind to all their friends on the Internet．A break would also make them more active，like socializing in person．This would finally help them focus better in school or in work．Although about 80% of people who take a break would come back to Facebook within days．

A．And 2.5 billion photos are added each month．
B．Wasting it on Facebook is not encouraging in any way．
C．This statistic isn't that bad but some people spend about 3-5 hours．
D．It is time people should take a break from Facebook once in a while．
E．As a result，the average Facebook users have 130 friends who they share links with．
F．Usually，when people hear the words"social networking"，their brains automatically go to sites such as Twitter or Facebook．
G．The main idea of Facebook is that you can keep in touch with all your friends around the world who have Facebook．

Riding Day
As I watch a single horse running across the field，I think back to when I saw my first horse．She was standing in a field．"Hold out your hand．Gentle now，"my grandfather said．Nervously，I did．Stepping toward me，she turned her head to inspect me with one coffee-colored eye．At that moment，I could have known she smiled．This was my first childhood memory，in which I realized that I would soon learn to ride her，and in my heart I felt like a true Comanche．
    For days after our first meeting，I sat in the field with my horse．I studied her as she studied me．I learned which grasses she preferred to eat； she would lift her head into the gentle spring wind that often blew across the field．
Finally，the time came to ride her．It was a tribal（部落的） tradition for younger men to spend most of their days hunting．This left the teaching to the elders，like my grandfather．These lessons were extremely important．Every boy was put on a horse before he could walk and was expected to be a skilled rider by age five．When the elders felt a boy was an expert，he was able to have his own horse．
On riding day，I told my horse that we both had much to prove today，and I remembered nuzzling her and kissing her long face．When she nuzzled me back，I knew she understood．I felt the days spent in the field with her had given me a strange belief in her--in us．I encouraged her to move，and with her head held high，she carried me．She was as proud of me as I was of her．
We succeeded．The elders of the tribe announced me a skilled horseman．I stood in a circle of men from my tribe．I could feel my heart beating quickly．Then the moment came when my father presented me with my first bow and arrow．I had never before seen so much pride in his eyes．
    Today my father leads the horse and his grandson--my son--climb upon his own horse in golden sunlight．My father insisted on teaching him to ride and doing it in the way of our people．Proudly，I stepped aside to let him do so．I smile，cherishing the details of this moment as much as I have always cherished the memories of my own riding day．

5．As part of an effort to improve treatments for life-threatening illnesses，a team of scientists have created rabbits that glow in the dark．
Their efforts have produced two rabbits out of a litter of eight that went from being a normal，soft white to glowing green in the dark．The rabbits were born at the University of Istanbul as part of the collaboration between scientists from universities in Turkey and Hawaii．
The rabbits glow to show that a genetic operation technique can work efficiently，though the specific color is more cosmetic than scientific．"The green is not important at all-it's just a marker to show the experiment can be done successfully，"said University of Hawaii associate professor，Stefan Moisyadi．
To produce the glowing effect，researchers injected jellyfish（水母）DNA into a mother rabbit's embryos．Then those embryos were inserted back into the mother．Similar experiments have resulted in glowing cockroaches（蟑螂）and cats．
Eventually，the researchers hope the technique can lead to new ways to produce medicines，Moisyadi said．
"The final goal is to develop animals that are able to produce beneficial molecules（分子）in their milk that can be cheaply extracted（提取），especially in countries that cannot afford big factories that make drugs，which usually cost US $1 bn to build．Then they will be able to produce their own protein-based medication in animals，"Moisyadi said．
The rabbits are expected to have the same life span as their non-glowing counterparts，but Moisyadi said he understands people can object to this kind of experimentation involving live animals．
"To the people against，I say：think about，what are the benefits and what are the injuries？"Moisyadi said．"And if the benefits outweigh the injuries，let's go with the benefits．"
Moisyadi，a native of Turkey who is now with the University of Hawaii，started developing the project in 2006，and researchers are now waiting to see if pregnant sheep produce similar results．
31．What do we know about the glowing rabbits？D
A．They live shorter lives than ordinary rabbits．
B．Their fur became green after the experiment．
C．They were chosen from a special species of rabbits．
D．The color that they glow isn't of interest to scientist．
32．Why did scientists conduct the experiment to create glowing rabbits？C
A．To research animal genes．
B．To improve animal species．
C．To produce cheap，beneficial medicine．
D．To improve animal's ability to resist disease．
33．Which animal wasn't used as the test subject？C
A．The cat．B．The jellyfish．C．The sheep．D．The cockroach．
34．Which of the following is TRUE，according to the passage？C
A．The project is supported by people．
B．The success rate in creating the rabbits is 20%．
C．The project has been conducted for more than nine years．
D．The project is mainly conducted by Turkish scientists．

A．Doubtful．B．Supportive．C．Disapproving．D．Indifferent．

15．Last year I ruined my summer vacation by bringing along a modern convenience that was too convenient for my own good：the iPad．Instead of looking at nature，I checked my e-mail．Instead of paddling a small boat，I followed my Twitter feed（推特简讯）．Instead of reading great novels，I stuck to reading four newspapers each morning．I was behaving as if I were still in the office．My body was on vacation，but my head wasn't．
    So this year I made up my mind to try something different：withdrawal（退出）from the Internet．I knew it wouldn't be easy，since I'm bad at self-control．But I was determined．I started by giving the iPad to my wife．
    The cellphone signal at our house was worse than in the past，making my attempts at cheating an experience in frustration （沮丧）．I was trapped，forced to go through with my plan．Largely cut off from e-mail，Twitter and my favorite newspaper websites，I had few ways to connect to the world except for the radio-and how much radio can one listen to，really？I had to do what I had planned to do all along：read books．
    This experience has had a happy ending．With determination and the strong support of my wife，I won in my vacation straggle against the Internet，realizing finally that it was I，not the iPad，that was the problem．I knew I had won when we passed a Starbucks and my wife asked if I wanted to stop to use the Wi-Fi．"I don't need it，"I said．
    However，as we return to post-vacation life，a harder test begins：Can I continue when I'm back at work？
    There are times when the need to know what's being said right now is great．I have no intention of giving up my convenience completely．But I hope to resist the temptation （诱惑）to check my e-mail every five minutes，which leads to checking my Twitter feed and a website or two．
I think a vacation is supposed to help you reset your brain to become more productive．Here I hope this one worked．
