Chat rooms and messaging can be great fun，but remember, you never really know who you are talking to online．It could be someone trying to trick you，some kind of weirdo（古怪的人），or someone really dangerous．Here are some tips to help you keep safe：

●  Never use your real name in chat rooms—pick a special online nickname．

●  Never tell anyone personal things about yourself or your family—like your address or telephone number ，or the school or clubs you go to．That goes for sending them photos as well. Remember, even if somebody tells you about themselves，never tell them things about you.

●  If you want to meet someone you’ve only spoken to once, remember that they might not be who they said they were. Only meet people in public places and take along an adult—they should do this too，because they don’t know who you really are either!

●     Never respond to nasty（淫秽的）or rude messages，and never send any either! If you feel suspicious or uncomfortable about the way a conversation is going，or if it’s getting really personal，save a record of it and stop the conversation．That way you can show someone and ask what they think．

●  Be careful with any email attachments（附件）or links that people send you，they might contain nasty images，or computer “viruses” that could ruin your PC．So if _______ who it’s from，don’t open it．

Many of us assume that with such a last name, Peter Buffett, 52, must enjoy a life of endless privilege. But the son of billionaire investor (投资人) Warren Buffett definitely doesn’t think so.

   “People who are born with a silver spoon in their mouth can fall victim (受害者) to what my father has called a silver dagger (匕首) in your back,” Buffett told Reuters in an interview. “It leads to a sense of entitlement (特权) and a lack of personal achievement.”

  Entitlement, he believes, is the worst thing ever. “Anybody who acts like they deserve (应得) something ‘just because’ is a disaster,” he said.

  In his new book, Life Is What You Make It: Finding Your Own Path to Fulfillment, Buffett says that the only real inheritance (遗产) handed down from his parents was a philosophy (价值观): Forge your own path in life. It is a belief that has allowed him to follow his own passions, establish his own identity, and reap (收获) his own successes.

  Did his father ever want him to go into finance? “It was encouraged for a moment when I was open to the idea,” he told Reuters. But as he grew older, it became clear the financial world “was not speaking to my heart.”

   His father accepted his choice to become a musician. He began his musical career by writing music for TV commercials (广告). He then released his own albums.

   “I am my own person and I know what I have accomplished in my life,” he told Reuters. “This isn’t about wealth or fame or money or any of that stuff, it is actually about values and what you enjoy and finding something you love doing.”

   Along with the book, Buffett has begun a “Concert & Conversation” tour in which he plays the piano, talks about his life and warns against consumerist (消费主义) culture and damaging the environment.

   “Economic prosperity (繁荣) may come and go; that’s just how it is,” he writes in the book. “But values are the steady currency (硬通货) that earn us the all-important rewards.”

What does “It” in the second paragraph refer to?

  A. A life of a top investor.          B. A silver spoon in the mouth.

  C. Being born to a wealthy family.  D. The victim of a silver dagger in the back.

What does the article tell us?

  A. Peter Buffett is a born musician.

  B. Peter Buffett enjoys a hugely privileged life.

  C. A wealthy family can benefit a child but also spoil him or her.

  D. Peter Buffett was forced by his parents to take over their business.

The article claims that Peter Buffett owes his achievements largely to ______.

  A. his passion for music      B. the good education he received

  C. his great determination        D. the values he learned from his parents

Which of the following statements would Peter Buffett probably agree to?

  A. Wealth is there to enjoy to the fullest.

  B. A person’s value lies within.

  C. Many people are fooled by economic prosperity.

  D. Young people should choose their own philosophy, whatever their parents believe in.

Though “nanometer” is now a fashionable term all over the world,few people know exactly what it is.It has become a new favorite of manufacturers and sellers in recent years.Many “high-tech” products bearing the name “nano” have entered the market,bringing more mysterious feeling to surprised consumers.

Nanometer is a very small length unit of measure,and is very small.One millimeter is 1000 micrometers,and one micrometer is 1000 nanometers.That is,one nanometer is one billionth of a meter.Nano materials are solid materials composed of particles or crystallites of less than 100 nanometer in size.Then,is a cup made of nano material really any different from an ordinary cup in function as far as how it works?

Are nano cups really so wonderful?A reporter went to the Institute of Nanomedicine,which is the first such institute of such a sort in the world and the only one in China,specializing in researching the investigation  of the application of nano technology into medicine.

Ji(director Institute of Nanomedicine):

A water molecule is composed of 2 hydrogen atoms and 1 oxygen atom.It can be alterchanged only by special manipulation of the atoms.The material constituting the cup can have a nanometer particles size of the nano level.But it cannot change the chemical and physical properties of the water contained in it.The water in the cup is still water.When people drink it,it will produce no special effect on human body.

Prof.Ji told the reporter,so far,the investigation of nano materials is still confined in the laboratory.No commercial micro products can be produced yet.With the present level of science and technology,the time of everyday goods age of daily use articles made of nanometer materials is still years away.

The commodities labeled with nano marks in the market now are only traditional products coated with a thin layer of nanometer material,which makes them more abrasion resistant,much easier to be cleaned,or oil repelling or moth proof.

Prof.Ji explained that nano cup is a real cup.It can also be included in the list of nano products in a certain sense.But the nano cup has not changed its property and function as a cup.It is not a magical medicine for curing and health care.

Which of the following shows the right relationship?

A.nanometer<millimeter<micrometer<meter

B.nanometer<micrometer<millimeter<meter

C.micrometer<millimeter<nanometer<meter

D.millimeter<micrometer<nanometer<meter

The underlined part in the last second paragraph but one is about_________.

A.the strong points of nano cups                        B.the shortcomings of nano cups

C.the uses of nano cups                                     D.the wonders of nano cups

Which of the following does not show that nano cups are different from ordinary cups?

A.Nano cups can’t make people healthier.

B.Nano cups are made of a different material.

C.Nano cups are much easier to be cleaned.

D.Nano cups are hard to produce.

According to the text,nano cups in the market are_________.

A.only traditional products

B.ordinary cups covered with a little nanometer material on the surface

C.cups made of a nano material

D.cups made of a mixed material

   Many scientists are now exploring the idea of going to live on Mars. Some other scientists from the MASA AMES Center(美国宇航局) have already started the creation of a “Mars town” and many others are in fact already experimenting with it. Of course, these experiments are done on Earth itself but this “Mars town” has an environment practically like that of Mars.

  The astronauts working in these towns wear their space suit and also do everything they would really have to carry out if they ever go to Mars in the future.

   But Mars would be like Earth, a temporary（临时的） place for humans. When the Sun starts swallowing up(吞掉) the planets, Mars will disappear only hours after Earth. So Mars only seems to be the ideal place to spread the human beings. It is also a good location to send humans if ever there is a disaster on Earth. By saying disaster, I mean asteroids(小行星) hitting and things like that.

   If we humans do not want to disappear when Earth or Mars gets swallowed up, we will have to go and live beyond the solar system. But are there any planets outside our solar system prepared to support life? Astronomers’ answer is:

   “If Earth can support life, why can’t other planets do the same too? Astronomers have already discovered a Jupiter(木星)- like planet orbiting a Sun-like star, so why not an Earth-like planet orbiting a Sun-like star?

   To achieve this goal though, many other problems have to be taken into consideration. How do we transform(改造) a dusty planet like Mars into one more or less like our Earth? How should we go on? There is still a long way to go.

The “Mars town” mentioned in the passage is ___________

   A. a research base on Mars.

   B. an experimental lab built on Earth.

   C. a strange place on Mars .

   D. a town existing in scientists’ imagination

We can know from the passage that astronomers probably think ____________

   A. it is impossible to transport humans to other planets.

   B. there may be an Earth-like planet outside the solar system

   C. humans will move to the new-found Jupiter-like planet

   D. there’s no need for humans to move beyond the solar system.

Why would Mars only be a temporary(临时) place for humans?

   A. The conditions there would be too hard for the human beings

   B. There would be more disasters like asteroids hitting.

   C .It would disappear when Earth disappeared.

   D. It would be too hot to live on.

The underlined word “orbiting” in the fifth paragraph is closest in meaning to “________”

   A. moving around           B. getting close to

   C. passing by quickly        D. going through

Which of the following would be the best title for this passage?

   A. Mars Town                           B. Living on Mars

   C. The Future of Earth                    D. Where to live in the Future

Andy rode slowly on his way to school, day-dreaming about the fishing trip that his father had promised him. He was so busy dreaming about all the fish he would catch that he was unaware of everything else around him.

He rode along until a strange sound drew him to the present. He came to a stop and looked curiously up to the heavens. What he saw shocked and terrified him. A huge swarm of bees filled the sky like a black cloud and the buzzing mass seemed to be heading angrily towards him.

With no time to waste, Andy sped off in the opposite direction, riding furiously—but without knowing how to escape the swarm. With a rapidly beating heart and his legs pumping furiously, he sped down the rough road. As the bees came closer, his panic increased. Andy knew that he was sensitive to bee stings(蜇). The last sting had landed him in hospital—and that was only one bee sting! He had been forced to stay in bed for two whole days. Suddenly, his father’s words came to him. “When you are in a tight situation, don’t panic. Use your brain and think your way out of it. ”

On a nearby hill, he could see smoke waving slowly skywards from the chimney of the Nelson family home. “Bees don’t like smoke,” he thought. “They couldn’t get into the house. ” Andy raced towards the Nelson house, but the bees were gaining ground. Andy knew he could not reach the house in time. He estimated that the bees would catch up with him soon.

Suddenly, out of the corner of his eyes, he spotted a small dam used by Mr. Nelson to irrigate his vegetable garden. Off his bike and into the cool water he lived, disappearing below the surface and away from the savage insects. After holding his breath for as long as he could, Andy came up for air and noticed the bees had gone. Dragging himself out of the dam, he struggled up the hilly slope and rang the doorbell. Mrs. Nelson took him inside and rang his mother.

“You’ll really need that fishing break to help you recover,” laughed his mother with relief. “Thank goodness you didn’t panic!” But Andy did not hear her. He was dreaming once again of the fish he would catch tomorrow.

A. He asked Mr. Nelson for help.          

B. He hid himself under the water.

C. He rushed into the Nelson house.
