Facebook means never having to say goodbye. The social media website has earned a reputation for reconnecting old friends. Last week，a guy whom I hadn't seen since my bachelor party five years ago sent me a friend request. I accepted and waited for “Easy E” to send me a greeting of some kind. He had sought me out，after all.
I learned from his profile that he was in a relationship and had a son. However，I'm pretty sure we won't ever write wall-to-wall，let alone email each other. But he'll remain a friend of online until one of us makes a point of removing the other from his official list.
My pool of friends consists of family members，college buddies，coworkers from past and present，and friends of friends. There are 35 in all. If I spent some time uploading old email addresses，I'm confident that I could increase my friend count actually.
A person could make a mission out of reconnecting with childhood friends，former classmates，distant cousins, and those one would like to get to know better. And some people can even handle hundreds of onscreen relationships，keeping up with the daily happenings of their small army of companions. After all，there are worse fates than having too many friends.
Thanks to email，the inability to schedule face-to-face meetings no longer means a friendship must come to a close. But even with email，people will lose touch if one or both parties stop writing back. That’s normal. People move from school to school，job to job，city to city. You never have to feel guilty for breaking away.
Every day，the masterminds of Web 2.0 find new ways of making human communication easier. However，convenience can be a crutch(拐杖)．Some things shouldn't be simplified. When it comes to friendship，there can be no shortcuts.According to Paragraph 1，the website is famous because ________.

During the next several weeks I went completely to the wolves. I took a tiny tent and set it up on the shore of bay. The big telescope was set up in the mouth of the tent in such a way that I could observe the wolves by day or night.
Quite by accident I had pitched (set up) my tent within ten yards of one of the major paths used by the wolves. Shortly after I had taken up residence one of the wolves came back and discovered me and my tent, but he did not stop or hesitate in his pace. Later, one or more wolves used the track past my tent and never did they show the slightest interest in me. I felt uncomfortable at being so totally ignored. The next day I noticed a male wolf make boundary markers by passing water on the rounds of his family lands.
Once I had become aware of the strong feeling of property rights which existed among the wolves, I decided to use this knowledge to make them at least recognize my existence. One evening, after they had gone off for their regular nightly hunt I staked out a property of my own, including a long section of the wolves’ path. In order to ensure that my claim would not be overlooked, I made a property mark on stones, dumps of moss, and patches of vegetation with a lot of tea. Before the hunters came back, task was done, and I retired, somewhat exhausted, to observe results. A few minutes later, the leading male appeared. As usual he did not bother to glance at the tent, but when he reached the point where my property line intersected (cut across) the trail, he stopped as suddenly as if he had run into an invisible wall.
Cautiously, he extended his nose and sniffed at one of my marked bushes. After a minute of hesitation he backed away a few yards and sat down. Then, he looked directly at the tent and at me.
His glare seemed to become more fierce as I attempted to stare him down. The situation was becoming intolerable. To break the impasse I turned my back on the wolf. Then quickly and with an air of decision, he turned his attention away from me and began a systematic tour of the area I had staked out as my own. As he came to each boundary marker he sniffed it once or twice, then carefully placed his mark on the outside of mine. Why did the wolves manage to ignore the author’s presence?
| A．Because his tent was out of the wolves’ estate boundaries. |
| B．Because the author and the wolves were already good friends. |
| C．Because they did not know him at all. |
| D．Because the wolves were afraid of strangers. |
Which is TRUE according to the passage ?
| A．The author likes staring matches esp. with wolves. |
| B．Staking the land was very easy. |
| C．Wolves can see the estate boundaries clearly with their eyes. |
| D．The author managed to know why the wolves ignore his presence. |
What was the author’s discovery?
| A．Wolves were not settled beasts, as is almost universally believed. |
| B．Wolves were settled beasts and the possessors of an estate with definite boundaries. |
| C．Wolves were not interested with strangers. |
| D．Wolves’ family was dominated by a female. |
Why did the author stake out an area of his own?
| A．Because he thought it better to be stared at than to be ignored. |
| B．Because he didn’t want the wolves to use the track past his tent. |
| C．Because he wanted the wolves to take cognizance of his existence. |
| D．Because he wanted to find out how fierce the wolf’s glare was. |
If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of our brains are not getting enough exercise and, as a result, we are growing old unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why quite healthy in northern Japan appeared to be losing their ability to think and reason at a rather early age, and how the speed of getting old could be slowed down.
With a team of researchers at Tokyo National University, he set about measuring brain volumes of a thousand people of different ages with different jobs. Computer technology helped the researchers to get most exact measurements of the volume of the front and side parts of the brain, which have something to do with intellect and feelings, and decide the human character. As we all know, the back part of the brain, which controls task like eating and breathing, does not contract with age.
Contraction of front and side parts—as cells die off—was seen in some people in their thirties, but it was still not found in some sixty and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction—using the head.
The findings show that contraction of the brain begins sooner in people in the country than in the towns. “Those with least possibility,” says Matsuzawa, “are lawyers, followed by university professors and doctors. White collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm worker, bus driver and shop assistant.” The team of doctors wanted to find out _____.
| A．at what point people grow mentally old |
| B．how to make people live longer |
| C．the size of certain people’s brains |
| D．which people are the most clever |
Their research findings are based on _____.
| A．an examination of farmers in northern Japan |
| B．tests given on a thousand old people |
| C．examining the brain volumes of different people |
| D．using computer technology |
The doctors’ tests show that _____.
| A．our brains contract as we grow older |
| B．one part of the brain does not contract |
| C．sixty-year-olds have better brains than thirty-year-olds |
| D．some people’s brains have contracted earlier than other people’s |
The most possible conclusion of the passage is that _____.
| A．most of us take more exercise |
| B．it’s better to live in the town |
| C．the brain contracts if it is not used |
| D．the more one uses his brain, the sooner he becomes old |
What if we could replace oil with a fuel which produced no pollution and which everybody had equal access to?The good news is that we can, In fact, we are swimming in it—literally.
Hydrogen is one of the building blocks of the universe ,Our own sun is basically ,a big ,dense cloud of the stuff ,And hydrogen can be used to create electricity for power ,heat and light.
The problem is that hydrogen is everywhere and nowhere at the same time , It does not exist as a material on its own ,but is always part of something else, So it has to be separated before it can be used.
Most commercial hydrogen in use now is created from natural gas , As oil will start to run out in around the year 2030.,it makes sense to produce as much hydrogen as possible as soon as we can ,But natural gas supplies will also begin to run out soon after, Another source is needed.
Researchers are now using electricity to make water into hydrogen ,Companies are working on the problem in their own areas ,The first commercial hydrogen ,”fuel cells”for computers and mobile phones have already come on to the market ,Auto companies have also invested over US ＄2billion in the production of hydrogen fuelled cars
Thd nations of a hydrogen fuelled planet would not fight over evergy recourses, There would be a great reduction in pollution ,The only by-product of creating hydrogen is pure drinking water—something that is very scarce in many parts of the world ,But that is not where the good news ends, Once the costs of producing hydrogen have been brought down ,it will possibly provide power for a third of the Earth ‘s population that has no electricity.
And electricity creates wealth, In South A frica over the last decade there has been a large programme of electrification, Thanks to the programme , people do not have to spend their days looking firewood to burn for heat, And with electric light , they can work long into the night.
Some scientists see radical changes in the way the human race co-operates, Hydrogen creates clectricity, and is also created by it. With dual use fuel cells, everyone who consumes energy could also produce it ,Late at night, a man drives home in London and connects his car into the “world-wide hydrogen web”, which it supplies with electricity ,A few hours later, a man in Beijing uses that electricity to power the hydrogen cell in his car, Hydrogen could be the first democratic energy source.
Like all dreams of the future, it seems very far away, But the threat of war and terrorism in the Middle East has made governments and businesses more aware of the need to edn oil dependency and spend more time and money on hydrogen resource, So maybe the threat of war is not a completely bad thing for the future of the human race.What does the underlined word “it”in the last but one paragraph refer to?
| A．wealth | B．hydrogen | C．electricity | D．fuel |
What is the problem with using hydrogen as energy?
| A．It has by-products |
| B．It has to be separated from other materials |
| C．It will make energy too cheap |
| D．It is too far away from us |
Why does the author give the example in the last but one paragraph?
| A．To tell us that we produce energy while using hydrogen power |
| B．To tell us that hydrogen power does not produce pollution |
| C．To show hydrogen power can stop war |
| D．To show hydrogen power is cheap |
What is the author’s attitude about the future?
| A．skeptical | B．negative | C．indifferent | D．positive |
What is the passage mainly about?
| A．war and energy |
| B．the future of hydrogen as an energy resource |
| C．the disadvantages of oil |
| D．How to end war |
The high cost of living in Sydney causes city parents to worry more about their children.
New research by the Financial Services Council (FSC)shows that 75% of metropolitan mums and dads say their ability to earn is important to the well-being of their kids, Tet a greater proportion(比例)of Sydney parents think children suffer emotionally by having two full-time working parents .AS a result 46%of Sydneysiders feel their Kids could be happier , against 38%of both Melbourne and regional New South Wales mums and dads.
The FSC research ,which interviewed 1200 parents across the country ,also shows 66% of Sydneysiders believe the happiness of their children would be greatly affected if they or their partner couldn’t work.
The FSC undertook the survey as part of its Lifewise campaign ,to encourage Australians to protect themselves against financial hardship.

In sydney ,the top factor for creating an ideal childhood is financial security ,at 92%.Fewer parents rate having a tigh-knit family(89%)or living near friends and family (85%)as important.
David and Ari Dearnley ,of North Manly ,said money pressure was hard to avoid in Sydney ,They both work and said family finances would be severely hard if one of them couldn’t
But only Mrs Dearnly has income-protection insurance, “I think that I don’t really need it yet”,Mr Dearnly ,37, said.
“I think he’s mad”,Mrs Dearnly ,also 27 ,said,“If David couldn’t work it would have a huge impact on our lifestyle.”
“Looks like I’ll be getting it tomorrow,”Mr Dearnly responded.What is the main idea of the passage?

Babies who are slow to gain weight in the first months of their lives generally catch up to their peers by age 13,a large UK study shows, Researchers said the results would make parents whose babies fail to put on weight quickly less worried.
The researchers looked at data from ,11,499 children who took part in a large study, It showed that 507 who were slow to gain weight in the first eight weeks of life recovered fairly quickly and had almost caught up by age 2. Another group of 480 who were slow to gain between eight weeks and nine months continued to put on weight slowly until they were seven years ,but then had a sudden increase and caught up by age 13, The different pattems of recovery between the two groups were likely due to different reasons for slow weight gain ,the researchers said, All the children were still lighter and shorter than their peers by the time they were teenagers ,but within the normal range.
The findings highlight the importance of monitoring a baby’s weight and height gain during the first few weeks and months ,but not creating anxiety with parents of slow-growing babies, said the study leader Prof Alan Emond from the University of Bristol.
“In the past, a lot of parents have been caused unnecessary anxiety by heaith professionals and this is a positive and reassuring message.”He said in many cases of slow growth where children do not follow the standard’curve’(曲线)it is just because they are following their genetic potential.
Dr Simon Newell, vice-president of the Royal College of Paediatrics and Child Health, said he broadly agreed with the concluslons of the researchers but stressed that poor weight gain was something that needed to be monitored closely, “I would encourage parents to use growth charts but if measurements show your baby is smaller than averager it may be completely normal, ”he said.What can we know from the findings of the research?
| A．All the cases of slow weight gain in the first months of the babies’ lives are caused by the same reason |
| B．Slow-growing babies will have the same height and weight with their peers by age13 |
| C．Many cases of children whose growth don’t meet the growing standard curve cannot be treated as abnormal |
| D．The findings won’t cause parents’ anxiety so monitoring a baby’s growth from his/her birth is unnecessary |
Which of the following statements is true according to the passage?
| A．It’s important to monitor a baby’s weight and height gain for new parents |
| B．New parents should feel anxious about their baby’s weight and height gain |
| C．Researches still couldn’t find the reasons for slow weight gain |
| D．All the children’s weight and height became normal by age 13 |
What does the underlined word in the fourth paragraph mean?
| A．Making sure something is certain to be true |
| B．Making someone calmer and less anxious |
| C．Confirming something is to happen again |
| D．Being sure that someone can be attracted |
Which of the statements would Dr Simon Newell agree to?
| A．To some degree, growth charts can help parents monitor their babies’ weight gain |
| B．It’s abnormal for babies are smaller than average |
| C．He agreed with the researchers completely |
| D．Babies’ weight gain can only be monitored and measured by using growth charts. |
The writer wrote this passage in order to
| A．tell us how to help babies grow faster |
| B．explain why babies are gain weight slowly |
| C．report on the findings of a research |
| D．reduce the anxiety of some parents |
