You had better think twice before posting a new photo or updating it to your Facebook profile. That’s because new research has found that social media use can lower some users’ sense of self-control over their lives. The research, which will be published in The Journal of Consumer Research, was based on the responses of 541 Facebook users in the United States.

“Using online social networks can have a positive effect on self-esteem(自尊) and well-being. However, these increased feelings of self-worth can have a damaging effect on behavior.” said researchers Keith Wilcox of Columbia University and Andrew Stephen of the University of Pittsburgh. “Because users care about the image they present to close friends, social network use enhances self-esteem in them who are focused on close friends while searching for information on their social network. This momentary increase in self-esteem leads them to display less self-control after looking through a social network.”

In other words, social media users have more self-esteem after using networks like Facebook. However, that momentary improvement in self-esteem lowers their self-control and leads them to do what they want, even if this is not good for them.

    In particular, the researchers found that social media users were more likely to do too much drinking and eating and have a higher body-mass index. Frequent Facebook users also were more likely to have certain financial problems, including a lower credit score and higher levels of debt.

    The researchers tied these feelings to the observation that social media users were less likely to exhibit modesty on their profiles, since feedback was not immediate.

    “These results are worrying given the increased time people spend using social networks, as well as the worldwide proliferation (激增) of access to social networks anywhere, anytime via smartphones and other small devices,” Wilcox and Stephen wrote. “Given that self-control is important for maintaining social order and personal health and happiness, this unnoticeable effect could have widespread impact. This is particularly true for adolescents and young adults who are the heaviest users of social networks and have grown up using social networks as a normal part of their daily lives.”

   A. Self-control.       B. Self-confidence.      C. Self-esteem.      D. Self-discipline.

Do you know of anyone who uses the truth to deceive (欺骗)? When someone tells you something that is true, but leaves out important in formation that should be included, he can give you a false picture.

   For example, some might say, “I just won a hundred dollars on the lottery (彩票). It was great. I took that dollar ticket back to the store and turned it in for on e hundred dollars!”

   This guy’s a winner, right? Maybe,  maybe not. We then discover that he bought $200 worth of tickets, and only on e was a winner. He’s really a big loser!

   He didn’t say anything that was false, but he left out important information on purpose. That’s called a half-truth. Half-truths are not technically lies, but they are just as dishonest.

   Some politicians often use this trick. Let’s say that during Governor Smith’s last term, her state lost one million jobs and gained three million jobs. Then she seeks another term. One of her opponents(对手) says, “During Governor Smith’s term, the state lost one million jobs!” that’s true. However, and honest statement would have been, “During Governor Smith’s term, the state had a net gain of two million jobs.”

   Advertisers(广告商) will sometimes use half-truths. It’s against the law to make false statements so they try to mislead you with the truth. An advertisement might say, “Nine out of ten doctors advised their patients to take Yucky Pills to cure toothache.” It fails to mention that they only asked ten doctors and nine of them work for the Yucky Company.

   This kind of deception happens too of often. It’s a sad fact of life: Lies are lies, and sometimes the truth can lie as well.

It was 4 o'clock in the morning when I received the phone call．

    “This is the emergency room calling and your son was just  41  in with severe burns on his face，neck and arms．We have called for a（n）  42   and are going to fly him to the burn unit in Seattle．” Seattle was 350 miles from his college，so we knew immediately this was  43  ．

    The doctor described the  44  ，which caused the burns．At 6 am，our son and his friends decided to barbecue hamburgers in the courtyard of their apartment．When they   45   the charcoal（木炭），it burst into flames because they had sprayed too much gasoline（petrol）．The flames  46  my son’s shirt tail and shot from his waist to well over his head．

       47  ，one of the boys was quick-minded，grasped my son，and  48  him on the grass．While it saved his life，it was not in  49   to save him from severe burns and the terrible scars（伤疤）．

    After he  50  from the treatments，the doctors told him they would not do plastic surgery（整容）for 6 months  51  it takes that long for the skin to stop shrinking and wrinkling．So，he had to return to college with scars typical of severe burns．

    When I was a child, my mother told my sister，who had a 10-inch, very  52__ scar on her arm，“Nancy，if you ignore the scar，other people will ignore it．It does not mean they will not  53  it，but it means it will not matter to them if it doesn’t matter to you．’’

    I  54   this wisdom on to my son．He took my advice to  55  and returned to school with his head held high--glad he was alive．

    By the end of the six-month waiting period，he decided that the scars did not  56  , so he made the  57  to give up any plastic surgery．

    We all have “scars” that we believe  58  people to keep away from us．And we spend a lot of time thinking that if only we looked different，or dressed differently，people would like us better． 

     But you see，people will only judge you by your looks，or your clothes，if you are judging yourself by these same  59  standards．Put your imperfections out of your mind and concentrate on what you value  60  yourself，and your beauty will shine through．

Do you know Australia? Australia is the largest island in the world. It is a little smaller than China. It is in the south of the earth. Australia is big, but its population is not large. The population of Australia is nearly as large as that of Shanghai.

   The government has made enough laws to fight pollution. The cities in Australia have got little air or water pollution. The sky is blue and the water is clean. You can clearly see fish swimming in the rivers. Plants grow very well.

   Last month we visited Perth, the biggest city in Western Australia, and went to a wild flowers’ exhibition. There we saw a large number of wild flowers we had never seen before. We had a wonderful time. Perth is famous for its beautiful wild flowers. In spring every year Perth has the wild flowers’ exhibition. After visiting Perth, we spent the day in the countryside. We sat down and had a rest near a path at the foot of a hill. It was quiet and we enjoyed ourselves. Suddenly we heard bells ringing at the top of the hill. What we saw made us pick up all our things and run back to the car as quick as we could. There were about three hundred sheep coming towards us down the path.

  It's not a new phenomenon, but have you noticed how many nouns are being used as verbs? We all use them, often without noticing what we're doing.

    I was arranging to meet someone for dinner last week, and I said “I’ll pencil it in my diary”, and my friend said “You can ink it in”, meaning that it was a firm arrangement not a tentative one!

Many of these new verbs are linked to new technology. An obvious example is the word fax, which is a shortening of facsimile originally, an exact copy of a book or document. We all got used to sending and receiving faxes, and then soon started talking about faxing something and promising we'd fax it immediately. So, nouns turn into verbs in two easy stages. Then along came email, and we were soon all emailing each other madly. How did we do without it? I can hardly imagine life without my daily emails.

Email reminds me, of course， of my computer and its software, which has produced another couple of new verbs. On my computer I can bookmark those pages from the World Wide Web that I think I'll want to look at again, thus saving all the effort of remembering their addresses and calling them up from scratch. I can do the same thing on my PC, but there I don't bookmark; I favorite—coming from “favorite pages”, so the verb is derived from an adjective not a noun． I wasn’t really sure whether people said this，but someone told me recently that they had favorited a site I was looking for and so they could easily give me its address.

In the late 1980s I noticed that lots of my friends had acquired pagers, and kept saying things like “I’ll page you as soon as I know what time we’re meeting”. They couldn't say it to me, though; 1 refused to have one． So my children bought me a mobile phone, now known simply as a mobile and I had to learn yet more new verbs. I can message someone, that is, I can leave a message （either spoken or written）for them on their phone．Or I can text them, write a few words suggesting when and where to meet, for example. How long will it be before I can mobile them, that is, phone them using my mobile? I haven’t heard that verb yet, but I’m sure I will soon. Perhaps I’ll start using it myself! 　

“I’ll pencil it in my diary” in the second paragraph probably means          .

    A. it was a firm arrangement　　　　　　　    　B. it was an uncertain arrangement

    C. the arrangement should be written as a diary     D. he prefers a pencil to a pen

A website address can be easily found if it has been＿____.

    A. emailed                   B. messaged                 C. favorited                D. texted

Which of the following has not been used as a verb, yet?

    A. message                   B. page                     C. email                            D. mobile

The best title for this passage is____．

A. New Verbs from Old Nouns　　　　B. The Development of the English language

    C. New Technology and New words    D. Technology and Language.
