While astronauts in space get to do many exciting things, they miss out on ordinary things that we all take for granted—being able to walk on firm ground, hanging out with family and digging into a slice of hot steaming pizza. Though not much can be done about the first two things, there may soon be a solution to the third one, thanks to this cool 3-D pizza printer!
About a year ago, NASA offered $125 ,000 to Anjan Contractor, a 3-D technology expert, to build a device (设备) that would allow astronauts to make pizza on demand. The mechanical engineer promised that his invention would produce pies in large quantities that looked, tasted and even smelled like pizza made in common ovens.
Late last year, the engineer presented a video of his first prototype (原型) that begins by creating a single slice of dough (面团) that is cooked and printed at the same time. Then comes the tomato “sauce” — a mix of tomato powder, oil and water and finally, a protein slice that resembles cheese. While the video doesn’t show the baking process, the inventor says that once the pizza is printed, it can be ready to be consumed in 7 seconds.
While the pie in the video looks delicious enough to attract any pizza lover, Anjan Contractor is far from ready for astronauts. That’s because he still has to find a solution to make the food container in the printer last for 30 years. Though that may sound unrealistic, actually it is not.
Anjan Contractor believes that the only way that is possible is that the water is removed from all the ingredients (配料) and then they are reduced to the powder form. This, as you can imagine, will not be so easy. But, while the printer may not be ready for space, it certainly looks ready enough for people on earth. Hopefully, NASA and Contractor will consider selling it to those not fortunate enough to go to Mars!

Our particular parenting style reflects our own way of “looking”. Here’s a great piece of writing reflecting parent’s particular ways on the parenting style that have become known humorously as helicopter parenting and submarine parenting.
Helicopter parents hover over their children, managing every aspect of their child’s life. On the contrary, submarine parents remain “hidden” coming to the surface when guidance is needed.
While helicopter parents may have the best intentions, in reality, they are raising children with few problem solving skills. Children with hovering parents never get the chance to face disappointment and build up their ability to recover from misfortune.
Think about your typical submarine. Submarines usually remain underwater. In case of a need for emergency surfacing, submarines can rise so quickly. They are driven partially out of the water. Submarine parents also remain out of sight, yet able to appear in the case of an emergency.
I admit I’m a submarine mom. My job as a parent is to have fun with my daughters while letting them explore and learn natural consequences. 
My older daughter found herself acting in commercials and making more than minimum wage as a teen. To give her a sense of the real world, I insisted she spend three weeks every summer, picking strawberries and earning $3.50 on a good day.
When my youngest daughter Sondra was six, she wanted a very expensive American Girl Doll. I cut the full color 18" picture out of the American Girl catalogue and had it laminated (压膜). “Here’s your American Girl Doll.” I said “When you turn nine, I’ll buy you the 3D doll on your birthday.” Sondra played with her flat doll for months, making clothes and furniture for her. She learned creativity. I saved $88.00.What is the text mainly about?
| A．Various means of transportation. |
| B．Funny experiences of a mom. |
| C．Humorous stories about parents. |
| D．Different styles of parenting. |
The underlined phrase “hover over” in Paragraph 2 is closest in meaning to “_____”.
| A．leave behind | B．fly around | C．watch over | D．set aside |
Which of the following can be learned about helicopter parents from the passage?
| A．They give their children proper guidance. |
| B．They try to do everything for their children. |
| C．They teach their children how to face failures. |
| D．They help their children explore by themselves. |
The author supports her point of view mainly by _____.
| A．stating facts and offering advice |
| B．using figures and giving evidence |
| C．analyzing data and drawing conclusions |
| D．making comparisons and giving examples |
Who do you think breaks the law in our society? If you believe that only tough guys commit crimes, you may have to think again. Unlike in the movies, we can’t divide the world into bad guys and model citizens. Real life is much more complex. In the same way that diseases range from the common cold to fatal forms of cancer, crimes vary in degree. For example, smoking in an elevator will inconvenience people, but much less than threatening them with a gun.
In addition to breaking the law themselves, people tolerate various levels of crime. Why can we tolerate some crimes? It may be that, by seeing others do something, we accept it more easily. For instance, most people will find it easier to speed on a highway when everybody else is driving over the speed limit. When people celebrate a sports championship, if they see someone breaking store windows, they might start breaking windows themselves or even steal from the store. So the people around us influence how much law-breaking we can tolerate.
We must also wonder whether seeing violence on television or reading about it in the newspapers every day makes us tolerate crime more than we should. We become used to seeing blood on the news on television, or in full color in newspapers and magazines. Because we see thousands of dead people on TV, maybe we just try to ignore the situation behind the violence.
If so many citizens tolerate violence and crime, or even commit crimes themselves, it may simply be because of the human mind. Our minds may not care about specific laws. Instead, our minds may have a system of values that usually prevents us from hurting other people to improve our own lives. Yet, when it comes to respecting the rights of a mass of anonymous (不知名的) individuals, we might not be so responsible. While most people would not steal a wallet containing $50, they may not mind cheating on taxes, because cheating on taxes does not hurt any one person. It hurts society, but “society” remains an abstract idea that is not as real as a neighbor or a friend’s friend.
When we realize that so many people have misunderstandings of law-breaking, it is not surprising that so many people tolerate crimes, or even break laws, including me. But how could we improve the level of honesty in our society? Would strict laws help make our society better? Probably not. Honesty will have to come from social pressure: in the family, at school, on the job, each and every one of us can encourage honesty by showing which behavior is unacceptable. And teaching respect should become everyone’s responsibility. According to the author, “Real life is much more complex.” probably means .
| A．there is a wide range of people and crimes in the real life |
| B．smoking in an elevator goes against laws in the real life |
| C．there are much more crimes than diseases in the real life |
| D．some model citizens sometimes break laws in the real life |

| A．They take no notice of the human mind. |
| B．They break the laws unaccepted in their minds. |
| C．They aren’t concerned about some particular laws. |
| D．They hurt other people to improve their own lives. |
People tolerate violence and crime because .
| A．their behavior is the same as that of most other people |
| B．they pay no attention to the truth behind the crimes |
| C．most unlawful acts are not harmful to the individual |

| A．To discuss whether laws are strict enough. |
| B．To remind people to behave with honesty. |
| C．To show people the importance of education. |

A Charlotte N.C. man was charged with first-degree murder of a 79-year-old woman whom police said he scared to death. Can the guy be held responsible for the woman’s death? Prosecutors (公诉人) said that he can under the state’s murder rule, which allows someone to be charged with murder if he or she causes another person’s death while committing or fleeing from a severe crime—even if he or she doesn’t kill someone on purpose.
But, medically speaking, can someone actually be frightened to death? We asked Martin Samuels, chairman of the neurology department at Brigham and Women’s Hospital in Boston.
Absolutely, no question about it.
The body has a natural protective method called the fight-or-flight response, which was originally described by Walter Cannon，chairman of Harvard University’s physiology department from 1906 to 1942. If, in the wild, an animal is faced with a life-threatening situation, the automatic nervous system responds by increasing heart rate, increasing blood flow to the muscles, and slowing digestion, among other things. All of this increases the chances of succeeding in a fight or running away from an aggressive beast. This process certainly would be of help to early humans. However, in the modern world there is obvious decline of the fight-or-flight response.
The autonomic nervous system uses the chemical messenger to send signals to various parts of the body to activate the fight-or-flight response. This chemical is poisonous in large amounts; it damages the organs such as the heart, lungs, liver and kidneys. It is believed that almost all sudden deaths are caused by damage to the heart. There is almost no other organ that would fail so fast as to cause sudden death.
By the way, any strong positive or negative emotions such as happiness or sadness can cause the same result. There are people who have died in excitement or in religious passion. There was a case of a golfer who hit a hole in one, turned to his partner and said, “I can die now”, and then he dropped dead. What is Martin Samuels’ attitude to the possibility of being frightened to death?
| A．Approval. | B．Disapproval. | C．Doubtful. | D．Indifferent. |
What can we learn about the fight-or-flight response according to the passage?
| A．The fight-or-flight response was raised and proved by Martin Samuels. |
| B．It is a natural protective method that can’t be found in all creatures but humans. |
| C．The ancient humans had a better fight-or-flight response than modern ones. |
| D．The fight-or-flight response is beneficial to both our actions and organs. |
What activity can we infer is less likely to damage the organs?
| A．Winning an unexpected fortune. |
| B．Missing a dead family member. |
| C．Watching a horror movie. |
| D．Listening to a sweet song. |
The purpose of the passage is ______.
| A．to explain why people will die of a heart attack |
| B．to offer some advice on protecting us from heart failure |
| C．to compare different kinds of feelings to cause a death |
| D．to show strong emotions can cause a sudden death |
