分析 他亲眼目睹了玉树,青海省的一个县城,被一次意想不到的地震所袭击的场面;但是玉树人民并没有灰心,发誓要把他们的家园变成一个更加美丽的玉树.

解答 答案:D
根据句意可知,第一个空表示泛指"一次意想不到的地震",由于空缺处之后的单词unexpected的首字母的发音为元音/?/;故此处应填不定冠词an;第二个空泛指的是"一个更加美丽的玉树",故在more之前加不定冠词a;故答案为D.

点评 本题考查了冠词的用法.做本题时,首先根据句意判断出空白处表示的是特指还是泛指,然后结合冠词的用法,选出正确答案;因此,做此类题时,需要熟练掌握定冠词,不定冠词以及零冠词的具体用法.

9.Keeping a busy social life among lots of friends may keep people thinner than spending hours doing some exercises,according to scientists.They say that socializing and meeting with friends help increase levels of brown fat in the body which burns calories(卡路里)to produce heat.
Living in an exciting social environment was found to reduce fat in mice's belly by half over four weeks,even if they ate more.US researchers say that social excitement aids weight loss by turning white fat into brown.White fat stores calories and makes us fatter,while brown burns energy to produce heat.Turning white fat into brown is extremely difficult,normally requiring long-term stay in cold conditions or exciting part of the body's nervous system.
However,scientists from Ohio State University now think that having a busy social life is an even more effective way of changing white fat into brown.The team came up with their theory by studying the effects of various living environments on mice.Those,who lived alongside a greater number of mice,had more space and toys to excite themselves and then lost far more weight over the course of the study than their"couch potato"fellows.
Study author,Dr Matthew During,whose team's findings appear in the journal Cell Metabolism,said,"I'm still amazed at the degree of fat loss that occurs."Explaining how new technology had threatened face-to-face socializing,he added,"It's not just a sedentary (久坐的)lifestyle and high calorie foods,but an increasing lack of social activities."Co-author Dr Lei Cao said,"Loneliness is a potential factor for cancer and death; it's equal to cigarette smoking to a certain extent.Social activities are very vital.,

67.What information can we get from the first two paragraphs?D
A.Brown fat stores calories and makes us fatter.
B.It doesn't take long to turn white fat into brown.
C.Social excitement helps gain more weight.

C.The research findings haven't been published so far.
D.Dr Matthew During wasn't convinced of the result.
69.We can conclude from the text thatC.
A.the fat in mice's belly was reduced because of the relaxing environment
B.a sedentary lifestyle and high calories foods influence people's social life
C.surfing the Internet may influence people's face-to-face communication
D.cancer and death are mainly caused for lack of social life
70.What's the main idea of the text?D
A.Brown fat is beneficial to people's health.
B.Socializing is unnecessarily important in people's daily life.

D.Socializing contributes to people's losing weight.
13.Foxes and farmers have never got on well.These small dog-like animals have long been accused of killing farm animals.They are officially classified as harmful and farmers try to keep their numbers down by shooting or poisoning them.
Farmers can also call on the services of their local hunt to control the fox population.Hunting consists of pursuing a fox across the countryside,with a group of specially trained dogs,followed by men and women riding horses.When the dogs eventually catch the fox they kill it or a hunter shoots it.
People who take part in hunting think of as a sport; they wear a special uniform of red coats and white trousers,and follow strict codes of behavior.But owning a horse and hunting regularly is expensive,so most hunters are wealthy.
It is estimated that up to 100,000 people watch or take part in fox hunting.But over the last couple of decades the number of people opposed to fox hunting,because they think it is cruel,has risen sharply.Nowadays it is rare for a hunt to pass off without some kind of conflict between hunters and hunt saboteurs (阻拦者).Sometimes these incidents lead to violence,but mostly saboteurs attempt to stop the hunt by misleading riders and disturbing the trail of the fox's smell,which the dogs follow.
Noisy conflicts between hunters and saboteurs have become so common that they are almost as much a part of hunting as running after foxes itself.But this year supporters of fox hunting face a much bigger threat to their sport.A Labor Party Member of the Parliament(议会),Mike Foster,is trying to get Parliament to approve a new law which will make the hunting of wild animals with dogs illegal.If the law is passed,wild animals like foxes will be protected under the ban in Britain.

10.When I was six years old,my mom told me that I could find anyone's number in the phone book.I used to look through the phone book for hours trying to find Michael Jordan's phone number.When I couldn't find it,I just dialed seven numbers.When someone answered,I'd ask,"Is that Michael Jordan?"Obviously,I always had the wrong number.
A year later I started playing basketball at my local recreation center.It was very big.I never thought in my wildest dreams that a basketball court could be inside a building.The recreation center had a special smell in it,sort of like hot rubber.I guessed it was from the shoes hitting the floor so fast and hard.The atmosphere on the court was carefree.Our biggest excitement of the day was when we actually made a shot.We celebrated wins over ice cream at a fast food restaurant.
I got good at it,and my confidence grew.I played it all the time until the sixth grade.As soon as junior high school came,I stopped playing basketball and focused on school.When senior high school started,I tried out for the school team and made it.We worked hard.Every week we did 300 push-ups and 300 sit-ups on our own.Our coach encouraged the sit-ups to keep stomach power,because it gave us so much control when we were playing basketball.If we didn't want to do the sit-ups and push-ups,we could practice dribbling (运球) and shooting more.It's just us,the ball,the court and the net.But don't take my word for it.See for yourself.After all,I'm just one kid playing the game.

7.Social Networking and Its Effect
Social networking has become an unquestionable part of our everyday lives.Those who have a life on the Internet do not always realize that they are losing their connections with the real world.Nowadays,a reputation online is more important.Some are even finding a way to make a living online.Social media seems to have quite the impact,especially on teenagers.
Years ago,before social networking existed,friends would go out and have a good time,and popularity in high school would be something of importance to a lot of people.Today,popularity means having a lot of followers on Twitter or Tumblr.Tumblr has its own way of creating"celebrities".Users are considered"Tumblr famous"if they have a high number of followers.Websites make us think that greatness is achieved just because thousands of strangers are familiar with your face.Popularity is not about having a lot of friends anymore; it is just about being known for absolutely nothing.
Social networking has its positives,considering it allows us to connect with friends and family in a matter of seconds.Although this is extremely useful,it is also destroying our ability to make real life conversations.People are attacked over the Internet,but do not say a word to each other in person.Social media is preventing us from standing up for ourselves the way we should be.Facebook limits our conversations that we have with people,which is why it is always better to strike up a conversation in person instead of through a computer screen.Social networking destroys the true meaning of human interaction.
Teens are finding new ways to make a living out of advertisements that they post on their social networking pages.Social networks allow them to make money without even getting up off the couch.Being out in the real world and working creates ways to communicate and is a crucial part of life,but that will be destroyed if young teens think it is okay to just make money through social media.Social networking makes things easier,but that does not always mean that it makes things better.
Social networking affects young lives and causes teens to grow up differently from how their older relatives have.They rely on their blogs and pages to communicate with people,keep up with the latest trends and enjoy their separate little world.Social media has ruined how life should be:fun,adventurous and exciting.Instead,it has turned most teenagers into anti-social couch potatoes.There needs to be a break from social networking so young people can once again live a real life in the real world.
