The Internet will open up new vistas (前景), create the global village——you can make new friends all around the world. That, at least, is what it promised us. The difficulty is that it did not take the human mind into account. The reality is that we cannot keep relationships with more than a limited number of people. No matter how hard the Internet tries to put you in communication, its best efforts will be defeated by your mind.
The problem is twofold（双重的）. First, there is a limit on the number of people we can hold in mind and have a meaningful relationship with. That number is about 150 and is set by the size of our brain. Second, the quality of your relationships depends on the amount of time you invest in then. We invest a lot in a small number of people and then distribute what’s left among as many others as we can. The problem is that if we invest little time in a person, our engagement with that person will decline until eventually it dies into “someone I once knew”.
This is not, of course, to say that the Internet doesn’t serve a socially valuable function. Of course it does. But the question is not that it allows you to increase the size of your social circle to include the rest of the world, but that you can keep your relationships with your existing friends going even though you have to move to the other side of the world.
In one sense, that’s a good thing. But it also has a disadvantage. If you continue to invest in your old friends even though you can no longer see them, then certainly you aren’t using your time to make new friends where you now live. And I suspect that probably isn’t the best use of your time. Meaningful relationships are about being able to communicate with each other, face to face. The Internet will slow down the rate with which relationships end, but it won’t stop that happening eventually.The number of friends we can keep relationships with is decided by______.

Two years ago my grandmother was going to turn 75. My family discussed what was the best way to celebrate. Should we throw her a party ? Should we take her on a trip ? We remembered that she had touched so many people’s lives, and there were so many people for her to consider. Then someone got the idea that we should include everyone in the celebration by turning it into a tribute（献礼）to my grandmother.
We secretly sent out letters to the people in Grandmother’s address book and asked them to send a letter with a memory that they had shared with her. People sent us letters with poems, stories and pictures. The deep feeling that was shared through the response（回应）surprised us. We compiled（编辑）these letters into a memory book and amazed her with it on the morning of her birthday.
The unusual thing about my grandmother’s friends was not the number that she had, but the connection they shared. In many ways this book of friendship was the greatest achievement of my grandmother’s life.
I believe that developing true friendships is one of the most important things that anyone can do in one’s lifetime. It is not a matter of the number of friends one has, but the quality of the bonds. If one has had at least one true friendship before dying, then one can say one has lived a successful life. I have made many friends and I believe I have begun to develop the same types of friendships my grandmother kept up over her lifetime. I only hope that I will be as successful as she has been.How did the author’s family celebrate Grandmother’s birthday ?

Let's face it．No one drinks diet soda for the taste．People drink diet soda in the hope that it will help them lose weight or at least keep them from gaining it．Yet it seems to have exactly the opposite effect, according to a new study．
Researchers from the University of Texas said those who drank two or more diet sodas a day had waist size increases that were six times greater than those who didn't drink diet soda．"What we saw was that the more diet sodas a person drank, the more weight they were likely to gain," said Sharon Fowler．
The study was based on data from 474 participants in a large, ongoing research project, where the participants were followed for nearly l0 years．
While the findings are surprising, they also offer some explanations．
Nutrition expert, Melanie Rogers, who works with overweight patients in New York, has found that when patients are switched from regular to diet soda, they don't lose weight at all．"We weren't seeing weight loss necessarily, and that was confusing to us," said Rogers．
So why would diet soda cause weight gain? No one knows for sure yet, but it could be that people think they can eat more if they drink diet soda, and so over-compensate for the missing calories．
A related study found some sweeteners （甜味剂） raised blood sugar levels in some mice．"Data from this and other potential studies suggest that the promotion of diet sodas and artificial sweeteners may be risky," said Helen P．Hazuda, professor at the University of Texas's school of medicine．"They may be free of calories, but not of consequences．"People drink diet soda to _____．
| A．enjoy its taste | B．achieve weight loss |
| C．stay in fashion | D．gain more energy |
The new study suggests that drinking diet soda _____．
| A．causes people to become heavier | B．helps people to be healthier |
| C．makes people much thinner | D．offers people more calories |
We can learn from the passage that _____．
| A．regular soda makes people lose more weight |
| B．diet soda does help reduce calories |
| C．diet soda drinkers tend to eat more food |
| D．most blood diseases come from diet soda |
The underlined word "They" in the last paragraph probably refers to _____．
| A．sweeteners |
| B．diet soda drinkers and sweetener takers |
| C．sodas |
| D．diet sodas and artificial sweeteners |
Driving to a friend's house on a recent evening, I was attracted by the sight of the full moon rising just above my friend’s rooftops. I stopped to watch it for a few moments, thinking about what a pity it was that most city people, myself included, usually miss sights like this because we spend most of our lives indoors.
My friend had also seen it. He grew up living in a forest in Europe, and the moon meant a lot to him then. It had touched much of his life.
I know the feeling. Last December I took my seven-year-old daughter to the mountainous jungle of northern India with some friends. We stayed in a forest rest-house with no electricity or running hot water. Our group had campfires outside every night, and indoors when it was too cold outside. The moon grew to its fullest during our trip. Between me and the high mountains lay three or four valleys. Not a light shone in them and not a sound could be heard. It was one of the quietest places I have ever known, a bottomless well of silence. And above me was the full moon, which struck me deeply.
Today our lives are filled with glass, metal, plastic and fibre-glass. We have televisions, cell phones, pagers, electricity, heaters and ovens and air-conditioners, cars, computers.
Struggling through traffic that evening at the end of a tiring day, most of it spent indoors, I thought: before long, I would like to live in a small cottage. There I will grow vegetables and read books and walk in the mountains And perhaps write, but not in anger. I may become an old man there, and wear the bottoms of my trousers rolled and measure out my life in coffee spoons. But I will be able to walk outside on a cold silent night and touch the moon.The best title for the passage would be______.
| A．The pleasures of modern life | B．Touched by the moon |
| C．A bottomless well of silence | D．Break away from modern life |
What impressed the writer most in the mountainous jungle of northern India?
| A．The nice moonlight | B．Complete silence. |
| C．No modern equipment | D．The high mountains |
Modern things (Paragraph 4) are mentioned mainly to______.
| A．show that the writer likes city life very much |
| B．tell us that people greatly benefit from modern life |
| C．show that we can also enjoy nature at home through them |
| D．explain that people have less chances to enjoy nature |

| A．advise modern people to learn to live |
| B．show the love for the moonlight |
| C．express the feeling of returning to nature |
| D．want to communicate longing for modern life |
There are some things humans can go without. We can lose a kidney or a lung, an arm or two and still live perfectly well. But some fish put us to shame. They can get by without stomachs.
One such fish is the stout longtom. The group it belongs to carries a more appropriate name: the needlefish. All needlefish lack stomachs. Their ancestors had them, but later they were lost.
The stout longtom can reach 1.3 meters in length, and lives near the sea surface. Like all needlefish, it can jump out of the water to escape its enemies. Tropical fishermen are sometimes injured by needlefish. In 1977, a 10-year-old Hawaiian boy was killed when a needlefish jumped through his brain. The longtom eats smaller fish. It teeth are not good at cutting fish into pieces, so it swallows fish whole.
Ryan Day from Australia and his colleagues wanted to know how the longtom digests its meaty meals without a stomach, so they ran some chemical tests about the fish.
Day’s results show that the longtom can consume food without the help of a stomach. It uses a special material called trypsin that can break down proteins without acid — although the approach is less efficient than using a stomach.
Because it’s a meat-eating animal, the longtom gets a lot of protein in its food, so it can afford this slightly less efficient system for absorbing it. Two plant-eating fish that Day studies actually had higher levels of trypsin in their body, as their food was low in protein.
Day thinks that the longtom and its stomachless relatives might actually have arrived at an energy-saving solution. He says that although the stomach is critical to many kinds of animal, the organ is “a fairly expensive organ to run”. This perhaps explains why some animals have got rid of theirs. What does the underlined phrase “get by” mean?
| A．Recover. | B．Fight. | C．Hunt. | D．Live. |
Ryan Day ran the chemical tests in order to find out how the longtom ______.
| A．catches smaller fish in the water | B．digests the smaller fish in its body |
| C．can jump so high to escape its enemies | D．uses acid to break down the protein |
What plays a key role in the longtom’s digestion process?
| A．Trypsin. | B．Acid | C．The stomach. | D．Protein in its body. |
Ryan Day’s results show that ______.
| A．the longtom can make acid easily |
| B．the longtom often waste energy |
| C．the longtom’s high-protein food helps its unique way of consuming food. |
| D．meat –eating fish have higher levels of trypsin in their bodies than plant-eating fish |
