21、 I was 16 years old the day I skipped school for the first time. It was easily done: Both my parents left for work before my school bus arrived on weekdays, so when it showed up at my house on that cold winter morning, I simply did not get on. The perfect crime!
And what did I do with myself on that glorious stolen day, with no adult in charge and no limits on my activities? Did I get high? Hit the mall for a shoplifting extravaganza (狂欢)?
Nope. I built a warm fire in the wood stove, prepared a bowl of popcorn, grabbed a blanket, and read. I was thrilled and transported by a book — it was Hemingway's The Sun Also Rises — and I just needed to be alone with it for a little while. I ached to know what would happen to Jake Barnes and Lady Brett Ashley and Robert Cohn. I couldn't bear the thought of sitting in a classroom taking another biology exam when I could be traveling through Spain in the 1920s with a bunch of expatriates(异乡客).
I spent that day lost in words. Time fell away, as the room around me turned to mist, and my role — as a daughter, sister, teenager, and student-in the world no longer had any meaning. I had accidentally come across the key to perfect happiness: I had become completely absorbed by something I loved.
Please note that absorption is not the same as distraction or obsession. To be absorbed by something is to become it and when we come out of it, we are richer for it. To be distracted by something is also to disappear, but not in a good way. We become nothing at all. We don't get enriched. And to be obsessed by something, finally, is to become consumed and destroyed by it. So the trick to happiness, then, is to find something that absorbs you and become that thing by pursuing it with devoted attention.
Looking back on it now, I can see that some subtle things were happening to my mind and to my life while I was in that state of absorption. Hemingway's language was quietly braiding itself into my imagination. I was downloading information about how to create simple and elegant sentences, a good and solid plot. In other words, I was learning how to write. Without realizing it, I was hot on the trail of my own fate. Writing now absorbs me the way reading once did and happiness is their generous side effect.

22、Decision making is the process of making choices by identifying a decision, gathering information, and assessing alternative resolutions. Using a step-by-step decision-making process can help you make more deliberate, thoughtful decisions by organizing relevant information and defining alternatives. 【1】
Step 1. Identify the decision
You realize that you need to make a decision. 【2】 This first step is very important. As the saying goes, “Well begun is half done”. You can view situations more objectively, make your ultimate goal clear and then make up your mind.
Step 2. Gather relevant information
Collect information before you make your decision: what information is needed, the best sources of information, and how to get it. This step involves both internal and external “work.”
Some information is internal. 【3】 Other information is external. You'll find it online, in books, from other people, and from other sources.
Step 3. Identify the alternatives
As you collect information, you will probably identify several possible paths of action, or alternatives. You can also use your imagination and additional information to construct new alternatives. 【4】
Step 4. 【5】
Draw on your information and emotions to imagine what it would be like if you carried out each of the alternatives to the end. Evaluate whether your need would be met or resolved through the use of each alternative. As you go through this difficult internal process, you'll begin to favor certain alternatives: those that seem to have a higher potential for reaching your goal. Finally, place the alternatives in a priority order, based upon your own value system.
Step 5. Choose among alternatives
Once you have weighed all the evidence, you are ready to select the alternative that seems to be the best one for you. You may even choose a combination of alternatives.
A．Confirm the aim
B．Weigh the evidence
C．Then list all possible and desirable alternatives
D．You'll get it after the final decision is carried out
E．You'll seek it through a process of self - assessment
F．Try to clearly define the nature of the decision you must make
G．This approach may help you choose the most satisfying alternative possible
23、Picture a pigeon(鸽子)resting on a telephone wire.Ready for takeoff, it raises its wings, springs into the air and flies away.This series of actions are so common that you prob-ably do not pay much attention to it.But University of Manchester biomechanical(生物力学)engineer Ben Parslew does.He Is trying to design robots that can jump and take off like birds.
Most traditional robots roll around on wheels,constrainingmobility ((灵活性).There is a need for more intelligent robots that"can jump over the thing that is in their way, Parslew says.To design such a machine, he turned to nature.""Birds are really good jumpers,”he notes.
The trouble is, when birds start to take off, they'll bend so far forward that, according to the rules of physics, they shoul d tip over and fall onto their beaks (鸟喙).Yet that does not happen.Parslew and his team used computer modeling to discover how birds avoid this ,They discovered that birds turned their bodies slightly backward while ready to jump.
Parslew thinks engineers can use this information to design robots that can not only jump well but also send themselves into the air more efficiently.Most human-engineered flying ma-chines require either long runways or flat surfaces for takeoff.Either way, they take a while to overcome gravity and gain altitude.
University of Southern California biomechanist Michael Habib, who was not involved in the study, says springs enable more rapid speed than wheels do.And many animals are masters of springs."A.house cat will beat a Lamborghini off the line for the first 100 feet, "he says.While the car has to speed up, the cat jumps itself into a run.The same movement explains how birds start flight.
“If you can understand how that works, " Habib adds,"you can build a robot that's good at running around and good at flying, and it will also be good at taking off suddenly in all kinds of conditions and landing quickly, m Parslew is now designing such a robot, as an alter-native to wheeled plane for exploring other planets.
【1】Why do birds' takeoff actions catch Ben Parslew's attention?
A．Because he is fond of wild animals.
B．Because he wants to design robots that can jump and take off like birds.
C．Because he is a biomechanical engineer.
D．Because he is curious about nature.
【2】The underlined word"constraining in paragraph 2 is closest in meaning to “”.
A．improving.
B．robbing.
C．continuing.
D．limiting.
【3】What will happen when birds start to take off?
A．They will jump first before taking off.
B．They will tip over and fall onto their beaks.
C．They will make their bodies slightly backward.
D．It will take birds a while to overcome gravity and fly to the sky.
【4】What is the meaning of researching birds' takeoff?
A．Making robots jump and take off like birds.
B．Improving the ability of a plane.
C．Inventing a robot which can speed up quickly.
D．Making robots fly more efficiently.
24、Researchers have 3D printed a heart using a patient's cells, providing hope that the technique could be used to heal hearts or engineer new ones for transplants.
“This is the first time anyone anywhere has successfully engineered and printed an entire heart,” Professor Tal Dvir said in a statement. Dvir is the senior author of the research, published on Monday in the journal Advanced Science.
The cells that made the heart came from a donor's fat tissue. Researchers separated the cells in the tissue from the rest of the contents. The cells were reprogrammed to become stem cells with the ability into heart cells. The cells and hydrogel were first used to create heart patches with blood vessels (血管) and, from there, an entire heart.
At this stage, our 3D heart is small, the size of a rabbit's heart,” Dvir said. “But larger human require the same technology.” Previously, scientists had been able to print only simple tissues without blood vessels.
Heart disease is the leading cause of death in the developing world. Heart transplantation is the only way to treat end-stage heart failure, highlighting the importance of developing techniques such as 3D printing, according to the authors.
Dvir also explained that using the patient's own cells is key to engineering the tissues and organs. “It's important because it prevents the possibility of rejection,” he said.
Next, the researchers plan to train the hearts to behave like real ones. Dvir explained, “The cells need to form a pumping ability; they can contract, but we need them to work together.”
If researchers are successful, they plan to transplant the 3D-printed heart in animal models and, after that, humans. “Maybe, in ten years ,there will be organ printers in the finest hospitals around the world ,and these procedures will be conducted routinely,” Dvir said.
【1】What can we know about the 3D-printed heart?
A．It is almost of the same size as the human heart.
B．It uses the cells coming from an animal fat tissue to 3D print a heart.
C．It can provide the technology human hearts required in the future.
D．It can replace the patient’s heart in treating heart disease in ten years
【2】What is the third paragraph mainly about?
A．Value of the new technique.
B．Procedures of dealing with cells.
C．Tips about heart disease treatment.
D．Materials used in the 3D-printed heart.
【3】What do we know from what Professor Tal Dvir said?
A．The researchers are successful in 3D printing human heart.
B．Every hospital will have organ printers around the world.
C．Researchers will transplant the 3D-printed heart in ten years.
D．Professor Dvir is looking forward to the success of the research.
【4】What’s the author’s purpose in writing the text?
A．To show how to 3D print a heart.
B．To promote heart disease research.
C．To introduce a medical breakthrough.
D．To call on people to care about health.
