9．Blogging may have psychological（心理的）benefits for teens suffering from social anxiety，improving their self-esteem（自尊） and helping them relate better to their friends，according to new research published by the American Psychological Association．"Research has shown that writing a personal diary and other forms of expressive writing are a great way to release emotional distress and just feel better，"said the study's lead author，Meyran Boniel-Nissim，PhD，of the University of Haifa，Israel．"Teens are online anyway，so blogging enables free expression and easy communication with others．"
Blogging has a stronger positive effect on troubled students'well-being than merely expressing their social anxieties and concerns in a private diary，according to the article published online in the APA journal Psychological Services?．Opening the blog up to comments from the online community intensified those effects．
The researchers randomly surveyed high school students in Israel，who had agreed to fill out a questionnaire about their feelings on the quality of their social relationships．A total of 161 students--124 girls and 37 boys，with an average age of 15--were selected because their scores on the survey showed they all had some level of social anxiety or distress．All the teens reported difficulty making friends or relating to the friends they had．The researchers assessed the teens'self-esteem，everyday social activities and behaviors before，immediately after and two months after the 10-week experiment．
Four groups of students were assigned to blog．Two of those groups were told to focus their posts on their social problems，with one group opening the posts to comments； the other two groups could write about whatever they wanted and，again，one group opened the blog up to comments．The number and content of comments were not evaluated for this experiment．The students could respond to comments but that was not required．Two more groups acted as controls--either writing a private diary about their social problems or doing nothing．Participants in the writing and blogging groups were told to post messages at least twice a week for 10 weeks．
Four experts，who held master's or doctoral degrees in counseling and psychology，assessed the bloggers'social and emotional condition via their blog posts．Students were assessed as having a poor social and emotional state if they wrote extensively about personal problems or bad relationships or showed evidence of low self-esteem，for example．
Self-esteem，social anxiety，emotional distress and the number of positive social behaviors improved significantly for the bloggers when compared to the teens who did nothing and those who wrote private diaries．Bloggers who were instructed to write specifically about their difficulties and whose blogs were open to comments improved the most．All of these results were consistent at the two month follow-up．
The authors conceded that the skewed（有偏向的） sex ratio was a limitation to the study．However，the researchers analyzed the results separately by gender and found that boys and girls reacted similarly to the interventions and there were no major differences．They said future research should attempt to control the subjects for sex．

分析 一份最新的研究表明博客是一種青少年表達(dá)內(nèi)心情感的一種方式，有助于幫助青少年提高自尊以及跟其他人更好的相處．
解答 50．C細(xì)節(jié)理解題，根據(jù)第三段實(shí)驗(yàn)隨機(jī)抽取了161名中學(xué)生做調(diào)查，their scores on the survey showed they all had some level of social anxiety or distress，問卷調(diào)查顯示這些學(xué)生都有社交問題．
51．D猜測詞意題．第四段實(shí)驗(yàn)過程表明，四組學(xué)生被分成兩個(gè)小組，一個(gè)小組在博客上表達(dá)內(nèi)心以及評論，另外一組或者寫日記或者什么都不做；所以controls在主要為了和第一組學(xué)生進(jìn)行對比，
52．B細(xì)節(jié)理解題．Students were assessed as having a poor social and emotional state if they wrote extensively about personal problems or bad relationships or showed evidence of low self-esteem這句話告訴我們實(shí)驗(yàn)的結(jié)果：在博客上抒發(fā)個(gè)人心情的學(xué)生從心里上獲益最大．
53．C細(xì)節(jié)推斷題．最后一段提到實(shí)驗(yàn)對象的性別比例有一定局限性，They said future research should attempt to control the subjects for sex．可見，在未來研究人員可能會(huì)對實(shí)驗(yàn)進(jìn)一步完善．
54．A主旨大意題．根據(jù)文章第一段以及全文內(nèi)容來看，主要告訴我們一項(xiàng)實(shí)驗(yàn)研究的結(jié)果：在博客上抒發(fā)內(nèi)心可以緩解青少年的心理壓力．
點(diǎn)評 本文屬于科教類閱讀題材，話題學(xué)生較為熟悉，難度不大．考查細(xì)節(jié)題較多，要求考生在答題時(shí)要把握第一段大意，即研究結(jié)果，接著會(huì)描述實(shí)驗(yàn)過程，最后會(huì)提到不足．把握這種說明文的結(jié)構(gòu)有利于考生答題．
