What makes a person a scientist? Does he have ways or tools of learning that are different from those of others? The answer is “no”. It is not the tools a scientist uses but how he uses these tools that makes him a scientist. You will probably agree that knowing how to use a power is important to a carpenter. You will probably agree, too, 
that knowing how to investigate(调查),how to discover information, is important to everyone. The scientist, however, goes one step further, he must be sure that he has a reasonable answer to his questions and that his answer can be confirmed by other persons. He also works to fit the answers he gets to many questions into a large set of ideas about how the world works.
The scientist’s knowledge must be exact. There is no room for half right or right just half the time. He must be as nearly right as the conditions permit. What works under one s
et of conditions at one time must work under the same conditions at other times. If the conditions are different, any changes the scientist observes in a demonstration must be explained by the changes in the conditions. This is one reason that investigations are important in science. Albert Einstein, who developed the theory of relativity, arrived at this theory through mathematics. The accuracy of his mathematics was later tested through investigations, Einstein’s ideas were shown to be correct. A scientist uses many tools for measurements. Then the measurements are used to make mathematical calculations that may test his investigations.

My house is made of wood, glass and stone. It is also made of software.
If you come to visit, you'll probably be surprised when you come in: Someone will give you an electronic PIN to wear. The PIN tells the house who you are and where you are. The house uses this information to give you what you need. When it's dark outside, the PIN turns on the lights near you, and then turns them off as you walk away from them. Music moves with you, too. If the house knows your favorite music, it plays it for you. The music seems to be everywhere, but in fact other people in the house hear different music or no music. If you get a telephone call, only the nearest telephone rings.
Of course, you are also able to want something. There is a home control console (控制台) which is a small machine that turns things on and off around you.
The PIN and the console are new ideas, but they are in fact like many things we have today. If you want to go to a movie, you need a ticket. If I give you the key to my car, you can use my car. The car works for you because you have the key. My house works for you because you wear the PIN or hold the console.
I believe that in ten years from now, most new houses will have the systems that I've put in my house. The systems will probably be even bigger and better than the ones I've got.
I like to try new ideas. I know that some of my ideas will work better than others'. But I hope that one day I will stop thinking of these systems as new, and ask myself instead, ”How did I live without them?”The writer’s house is made of the following EXCEPT_________.

When was the last time your family sat down together to have a dinner?
The speed at which we live today no longer allows for slow eating habits. Most people work long hours. There is lots of fast food and eating out is now on the increase. Often, food is eaten in front of the television in silence, or a child eats alone in front of the computer.
When I was a child, every evening around the same time, one of the children would be asked to set the table, and then we'd go and wash our hands: before the meal. This was the time of day when we would talk about our day at school. But now things have changed a lot.
A family environment plays an important role for children in learning to communicate with others and understanding table manners, such as waiting for others to finish before leaving the table and not speaking with a mouth full of food. Parents’ likes and dislikes of a certain food will also influence a child's own likes and dislikes. Studies have shown that children who often eat with their families have better results at school than children who eat with their families less than twice a week.
Regular meal times give children the chance to discuss their problems with family members. They can also learn to respect others around the table. Talking to your children over dinner is the best way of having their-trust. Children learn good eating habits from their parents at a very young age. Family meals are important. Prepare them for your children.Some families eat less together because __________.
| A．most children live in a school |
| B．people are busy with their work |

Children who often eat with their families _________.
| A．turn out to do better in their studies |
| B．prefer to share food with others |
| C．show concerns about families |
| D．are interested in cooking |
Which word can best describe the writer's attitude towards eating together with families?
| A．Supportive. | B．Doubtful. | C．Worried. | D．Grateful. |
Which would be the best title of the passage?
| A．Table manners of a family | B．The importance of meals |

Every year in late spring at Wild Friends, the wildlife health center, workers receive baby animals, including songbirds and rabbits. This is the busiest time when workers care for and raise all the little ones before sending them back into the wild.
There are many reasons for these little animals' coming to the center. First of all, street cats or dogs catch, injure or take away little birds from their nests. Sometimes people catch baby animals and keep them at home, giving them food that they are not used to. It would make them sick. Most people don't realize that it's against law to get live animals out of their nests.
As for songbirds, people often find them on the ground in their yards, thinking they have no other choice but to leave them on the ground to die. This is because many people wrongly believe that once a bird is touched by a person, its mother will not accept this child bird. But that's not true.
If a little bird falls out of the nest, you should check whether it is injured. If not, you should put the bird back in the nest. If the bird is injured, call your local wildlife center quickly.
As for the progress of protecting wild animals, people at Wild Friends devote all their energy to this work. Over the last weeks, they have been able to send many of the birds and rabbits that came here earlier this spring back to nature.Which is the busiest season for workers at Wild Friends?
| A．Spring | B．Summer. | C．Autumn. | D．Winter. |
Which of the following will probably injure young birds?
| A．Giving them food they don't like. | B．Letting them play with children. |

| A．wait for its mother | B．help it go back home |
| C．touch it with your hands | D．call workers at Wild Friends |
Life on Mars could become a reality and it could happen in your lifetime.
A welcoming planet
Scientists say Earth’s neighbor Mars, a bright red planet about half Earth’s size, is the most likely to support human life. Mars even has frozen water on its surface.
Since the late 1990s, NASA has been exploring Mars using remote-controlled vehicles（装置）. Most recently Curiosity, a car-size vehicle, traveled through space on an unpiloted spacecraft(航天器) and landed on Mars in August 2012. Directed by NASA scientists , the vehicles move on the surface, taking pictures , collecting and analyzing soil, and looking for signs of life.
But what about human explorers? Plans are already in the works to send astronauts to Mars as soon as the mid-2030s.
_____________________________________
But before you start packing your bags, let’s consider the challenges. For starters, Mars is far away. Just getting there could take up to 10 months.
Scientists already know that time away from Earth’s gravity harms the human body. Bones and muscles get weaker. The body produces less blood. What damage would months and months of living in space do?
And then there is the matter of water, oxygen, food and fuel. Scientists will have to find solutions to these problems, or the first humans on Mars won’t survive very long in their new home.
Tiny Dangers
There’s another tinier risk. It’s so tiny that you can’t even see it: germs.
Some scientists believe that our germs could pollute the whole planet of Mars. Potentially killing Martian life before we have the chance to discover it. Worse, there is a small but terrifying chance that any microscopic life already there might be harmful to us .
Worse still, if any of those Martian germs(火星细菌) were brought back to Earth, the result could be disastrous. Animals, plants, and people could be wiped out.
Worth the $$$?
A more practical concern is the cost. The price could approach $ 1 trillion(万亿). How can we justify spending that much when so many problems—poverty, disease—could use the cash here on Earth?Which of the following is TRUE according to the “A welcoming planet” part?
| A．Mars is a little bigger than Earth. |
| B．There are flowing rivers on Mars. |
| C．People haven’t been to Mars so far. |
| D．Scientists have discovered signs of life on Mars. |
Which of the following can best fill in the blank in the passage?
| A．Living in space. | B．Limited resources. |
| C．Extreme conditions. | D．Interesting challenges. |
By “Tiny dangers” the author means ________________.
| A．there is no serious danger |
| B．people won’t be in any danger |
| C．it’s difficult for people to realize the danger |
| D．the danger may be caused by very small things |
Which may cause the biggest danger?
| A．Martian germs may be different from those on Earth. |
| B．Martian germs may be brought back to Earth. |
| C．People may carry germs to Mars. |
| D．There may be germs on Mars. |
Which section of a newspaper is the passage most probably taken from?
| A．People | B．History | C．Science | D．Business |
