I trained hard every day. Since I wanted to be the best I could be, I knew I would have to set some clear goals for myself. A couple of my goals were: run a 135-mile ultra-marathon(超级马拉松) across Death Valley, win the Badwater Ultra-Marathon, and run a marathon to the South Pole.
I had no idea how I was going to achieve these goals, but they certainly encouraged me to work hard. Today, I am really grateful to say that I have achieved all of them. Shortly after completing these goals, I set another goal: to run fifty marathons, in fifty states, in fifty days. Nobody had done anything like this before. To be honest, I was not quite sure if I could. But there was only one way to find out…so I just started training and preparing to give it my best try.
I completed that goal one year ago, and it felt great! But for me, life is not all about achieving goals. Sure, it feels good to succeed, but the greatest reward for me was learning more about myself and what I was able to do.
Only by stepping out into the unknown and stretching(使倾注全力) ourselves can we really discover what our true potential(潜能) is。

解析
试题分析：本文主要讲述作者在生活中给自己树立了一个又一个的目标，然后朝着这些目标努力，发挥出自己的潜能。目的在于建议我们也给自己树立人生发展的目标。
小题1:A 推理题。根据文章第二段Since I wanted to be the best I could be, I knew I would have to set some clear goals for myself.可知在我的成功中，目标是很重要的一环，正是因为设立了目标，所以我们才会向着自己的目标努力，最后才会完成目标。故A正确。
小题2:.B 细节题。根据文章第三段倒数第2行To be honest, I was not quite sure if I could.可知我也不确定自己是否会成功，故B正确。
小题3:C 推理题。这里的that goal 是承接第三段中的树立的I set another goal: to run fifty marathons, in fifty states, in fifty days.这个目标，我在一年之前就已经完成了。故C正确。
小题4:D 推理题。根据文章最后一段Only by stepping out into the unknown and stretching(使倾注全力) ourselves can we really discover what our true potential(潜能) is。可知当我们全力以赴的时候，我们就能发挥出我们全部的潜能。故D项表述是正确的。

举一反三
Our nature includes not just humans but plants and animals as well. Everything in our environment is connected in a complex cycle. If you have a better understanding of how animals would behave and work with us, then you would value nature better.
Some animals are actually misunderstood by people like sharks and snakes. These creatures are thought of as human killers, and this is mainly because we don’t understand why they behave that way. In zoology you would be able to learn natural behavior as well as their homes so you would completely understand why they would behave in a defensive(防御的) manner when they seem to be threatened. Studying zoology would help people achieve clearness over the common myths we have on different wild animals.
Studying zoology would help people know the real facts about animals. One of the negative facts is the decreasing numbers of some species of animals. It makes people realize that there is a need for nature to be always balanced. We need animals to keep the balance in our environment and for humans to survive as well. It would help us learn the needs that animals lack and we can respond by thinking of solutions we can give to the endangered species of animals.
Modern progress is needed for a country to grow in terms of its economy; however, it should not force us to destroy our rainforests and oceans. People should realize that our modern lives should include the lives of the animals that live with us. They should not be contained in zoos but in their natural homes as well. We will learn that every living creature on the earth has the right to own a home and we need to fight for them to have permanent(永久的) homes.
小题1:According to the text, nature should be .
| A．left alone | B．treated seriously |
| C．taken for granted | D．taken lightly |
| A．making our world beautiful | B．protecting species of plants |
| C．providing food for humans | D．keeping nature in balance |
| A．caretakers | B．killers | C．competitors | D．trainers |
| A．The Ways of Protecting Animals |
| B．The Importance of Studying Zoology |
| C．The Introduction to Zoology |
| D．The Advantages of Learning Zoology |
Now, scientists in California say they have come up with a way to turn a living cell into a memory device.
It can store only one tiny bit of information, but it’s a start. In the future, a cell-based gadget might travel through the body and record measurements. The benefit to human health could be big: the right tool, for example, might record the earliest signs of disease.
Doctors, scientists and other curious people want to know what is happening inside the body, even at levels that can’t be seen by the naked eye. So far, there is no device small enough to travel through the bloodstream.
If normal machines won’t do the trick, perhaps biology will. Scientists who work in the field of synthetic (合成的) biology are trying to find ways to turn living things into human tools. In the case of the new memory device, bioengineers from Stanford University used the genetic material inside living cells to record information.
This genetic material consists of DNA. Found in nearly every cell, DNA carries all of the information that keeps a living thing alive.
In the new experiment, the researchers turned DNA from bacteria(细菌) into a switch. They “flip (翻转)” a small section of DNA. Then, using the same procedure (过程) , the scientists flip the section again—returning it into its normal structure.
Using these DNA switches, “We can write and erase DNA in a living cell,” bioengineer, Jerome Bonnet, explained to Science News.
It might take years before his team or others identity whether a DNA-based memory device might be practical. Right now, it takes one hour to complete a flip. That is far too long to be useful. Plus, a flipped section has a very small little memory—less than what a computer uses to remember a single letter.
“This was an important proof that it was doable,” Bonnet told Science News. “Now we want to build a more complex system, something that other people can use.”
小题1:What is the aim of listing the electronic things in the first paragraph?
| A．To make the passage more fashionable. |
| B．To show how electronic things have memory. |
| C．To discuss things in detail. |
| D．To make the subject of the text more understandable. |
| A．To detect disease at the earliest point. |
| B．To help improve the memory. |
| C．To help people build a body. |
| D．To replace many electronic gadgets. |
A. The cells of bacteria.
B. The DNA of bacteria.
C. A section of bacteria.
C. The nucleus of bacteria.
小题4:What do we know about a flipped section of DNA?
| A．It has a very small memory. |
| B．It can function as a computer. |
| C．It has one letter in it. |
| D．It takes a day to complete it. |
There are different forms of color blindness. In some cases a man may not be able to see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person can’t tell the differences between blue and green. In rare cases an unlucky man sees everything in shades of green--- a strange world in deed.
Color blindness in human beings is a strange thing to explain. In a single eye there are millions very small things called “cones”. These help us see in a bright day and tell the differences between colors. There are also millions of “rods”, but these are used for seeing when it is nearly dark. They show us shapes(形状) but not color. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects but a blue lamp will. In similar way human being also have favorite colors. Yet we are lucky. With the aid of cones in our eyes we can see many beautiful colors by day and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around us.
小题1:The passage is mainly about ______.
| A．color and its surprising effects on drivers |
| B．women being luckier than man in that fewer of them are color blind |
| C．danger caused by color blindness |
| D．color blindness and how our eyes tell different colors and shapes |
| A．tell different colors | B．see in weak light |
| C．tell different shapes | D．tell orange from yellow |
| A．Women are more careful. |
| B．There are fewer color blind women. |
| C．Women are fonder of driving than men. |
| D．Women are weaker but quicker in thinking. |
| A．Not all of them have the same problem in recognizing colors. |
| B．None of them can see deep red but all can tell blue from green. |
| C．None of them can tell blue from green but all can see deep red. |
| D．All of them are lucky enough to see everything in shades of green. |
● To save time and money, use the college’s bus system. Taking the bus to school is quick, easy and free in most college towns. You won’t have to locate or afford a place to park either. It’s also a good way to be environmentally aware.
● Save pennies on books by waiting until class starts. You might not even need all of the recommended books. New textbooks cost an arm and a leg. Try buying used textbooks — it’s a surefire way to save money and serves the purpose as well.
● Do never look at college life as an endless series of parties and social activities. But there is a whole lot more to college if you’re serious about graduating. Having a good college experience is all about balancing work and fun.
● Be aware that your living environment can largely affect your academic success. If the dorm doesn’t suit you, consider living at home with your family or renting your own apartment. The best location for your studies isn’t always your dorm. Find a quiet area, like the library, to do your work. Alternatively, buy some headphones that block out noise.
● Be mindful of your diet. Make healthy food choices and watch what you eat. Avoid foods that are processed or high in sugar. The “freshman 15” is real. Many college students gain at least 15 pounds during their freshmen year.
● While electives (选修课) can be helpful when figuring out your major, you shouldn’t entirely rely on them. Clubs and other organizations exist around. Get involved. Make sure, though, that you still have time to study. Having too much on your plate can hurt your grades.
小题1:Which of the following ideas can be financially wise?
| A．Driving your own car. | B．Buying used books. |
| C．Renting an apartment. | D．Attending activities. |
| A．academic failures | B．physical problems |
| C．traffic accidents | D．social activities |
| A．attend limited activities on campus |
| B．have little regular physical exercise |
| C．focus less on their academic work |
| D．take relaxed attitudes to their diets |
| A．using too much money for meals |
| B．eating too many unhealthy foods |
| C．taking part in too many after-class activities |
| D．taking an elective that has too many students |
Scientists played a selection of music to a group of South American cotton-top monkeys but the only sound that got a reaction were from the heavy metal band Metallica. They were seemingly disinterested in Led Zeppelin, Miles Davis and Bach, but after the beautiful sound of Master of Puppets by Metallica was played the monkeys calmed down.
"Monkeys interpret rising and falling sounds differently than humans. Oddly, their only response to several samples of human music was a calming response to the heavy-metal band Metallica," said Professor Charles Snowdon, from the University of Wisconsin-Madison.
Rather than making them excited or aggressive, the heavy metal tracks had a comforting effect. Dr Snowdon, who teamed up with National Symphony Orchestra musican David Teie, also played the monkeys music composed specifically for them. Although they enjoyed Metallica, they were much more interested in these pieces.
A melody(乐曲) based on the short calls of scared monkeys led to anxiety levels rapidly growing, researchers found, while one based on long calls the creatures make when they are happy had a calming effect.
Frans B.M. de Waal, a professor of psychology at Emory University who studies animals, said the findings appear to say more about how monkeys respond to the sounds they make than they do about music or the evolution of music.
Dr Snowdon no longer has a monkey colony to use in his research, but he said his co-author David Teie is exploring the concept of music for cats.
"If we understand how we can affect their emotional states through using musical sound and aspects of our speech, maybe those of us living with companion animals can have a better relationship with them, too," Snowdon said.
小题1:The research mentioned in the passage is mainly about ______.
| A．the change of music over time | B．animals’ response to music |
| C．special music for animals | D．the origin of music |
| A．looked anxious | B．became restless |
| C．felt at ease | D．made long calls |
| A．of Led Zeppelin | B．of Miles Davis |
| C．of Metallica | D．specially composed for them |
| A．build better ties between animals and humans |
| B．compare monkeys and cats in term of music |
| C．develop new music based on animals’ calls |
| D．find better ways to keep animals under control |
