1 . Like many young people, Jessica wants to travel the globe. Unlike most of them, this 25-year-old is doing it _______ . She and her husband have spent the last two years traveling the world, stopping everywhere from Paris to Singapore. It might sound like one long, expensive _______ , but the couple has an unusual way to make their travel _______ .

They’re part of a new form of the _______ economy: an online group of house sitters. Throughout their no-cost stays in _______ homes, they feed pets and water plants in the homeowner’s _______ .

It’s not all sightseeing. The two travelers carefully _______ their trips, scheduling their days around the pets that are sometimes difficult to _______ . But house sitting also offers a level of _______ they can’t find in a hotel. “It’s like ________ at a friend’s house,” Jessica says.

The couple has a high ________ rate in getting accepted as house sitters and they always go beyond the homeowner’s ________ . For Jessica, that means ________ plenty of pictures of happy pets, keeping the house ________ and leaving a nice small gift before heading to the next house. “You want to make the homeowner feel that they made the right ________ ,” she says.

2 . My life as a tax-paying employed person began in middle school, when, for three whole days, I worked in a baking factory.

My best friend Betsy’s father was a manager at Hough Bakeries, which, at Easter time, _________ little bunny (兔子) cakes for all its _________throughout Cleveland. It happened that the plant downtown needed eight kids for _________ help during our spring break, for which I had no_________ beyond listening to my favorite records. I’d _________ minimum wage. I’d see how a factory_________. My parents thought all of this was a grand idea and called Betsy’s dad with their _________.

Our_________in the factory were simple: Place cakes on a moving belt. Attach icing (糖霜) ears. Apply icing eyes and nose._________ bunny from the belt. This was ____________ than it sounds.____________ a bit and the cakes pile up. As I told my parents at dinner that first night, it was all a little more high-pressure than I’d   ____________ .

Dad __________. The son of a grocer, he’d spent the summers of his childhood____________ food in Benardsville, New Jersey. This was the sort of work that made you____________ the dollars you earned and respect those who did the work, he told me.

3 . Dr. Smith of New York works at a center for children who can’t learn well. One day a father brought his son to him for________ at his office.

The father told Dr. Smith about his son. “My son has ________ in learning and can’t even play baseball. He isn’t doing well because he doesn’t try. I have done everything for him. I have even shouted at him. But nothing ________. ”

After Dr. Smith tested the boy, he ________ his father. He asked the father to sit in front of a ________ and then gave him a pencil and a piece of paper. There was a ________ on the paper. He asked the father to look only in the mirror and ________ the lines of the star with the pencil. The father made the same ________ anyone makes. Every time he ________ the pencil, it went the wrong way. The father’s face became red.

At this ________ the doctor shouted at him, “Hurry up! Why are you ________ so long? You can’t do such an ________ thing! You don’t know left from right!” These ________ made the father very angry.

“Now you can ________, can’t you?” The doctor said to him. “Your son has felt just like that all the time. You scolded (训斥) him too often, so he didn't try any more. He was afraid of making mistakes. ”

________ the father understood everything. He put his face down. Now he felt so sorry.

4 . The days that make us happy make us wise.

--- John Masefield

When I first read this line by England's Poet Laureate, it _____________   me.   What   did Masefield mean? Without thinking about it much, I had always assumed that the _______ was true. But his serious assurance was ________. I was deeply attracted by it.

Slowly, I seemed to ________ his meaning and realized the wisdom that happiness makes possible lies in clear perception(洞察力), not _______ by anxiety nor dimmed by despair and boredom, and without the blind _______ caused by fear.

Active happiness---not mere satisfaction or _______---often comes suddenly, like an April shower or the unfolding of a bud. Then you discover what kind of wisdom has ____________ it. Amazingly, in your eyes, the grass is greener; bird songs are sweeter; the _________   of your friends are more understandable, and more forgivable. Happiness is like a pair of eyeglasses correcting your ________ vision.

Nor are the __________ of happiness limited to what is near around you. Unhappy, with your thoughts focused on your emotional woes (痛苦) , your vision is cut short as though blocked by a wall. Happy, the wall _________.

Consequently, the long vision is there for the seeing. The ground at your feet, the world about you---people, thoughts, emotions, pressures---are now ____________ a larger scene. Everything covers a fairer _________. Everything around you, whether it is encouraging or frustrating, no longer seems such a big deal. And here is the beginning of _________.

5 . During the initial stages of instructed L2 (the second language) acquisition students learn a couple thousand, mainly high frequency words. Functional language proficiency, however, _______mastery of a considerably large number of words. It is therefore _______ at the intermediate and advanced stages of language acquisition to learn a large vocabulary in a short period of time. There is not enough time to _______the natural (largely incidental) L1 (the first language) word acquisition process. Incidental acquisition of the words is only possible up to a point, _______, on account of their low frequency, they do not _______often enough in the L2 learning material.

Acquisition of new words from authentic L2 reading texts by means of strategies such as contextual deduction (演绎) is also not a _______for a number of reasons. There appears to be no _______to intentional learning of a great many new words in a relatively short period of time. The words to be learned may be _______in isolation or in context. Presentation in bilingual (双语的) word lists seems an _______shortcut because it takes less time than contextual presentation and yields excellent short term results. Long term memory, ________, is often disappointing so contextual presentation seems advisable.

Any suggestions on how to use this in educational contexts should be based on a systematic ________ of the two most important aspects of the L2 word learning problem, this is to say,   selecting the relevant vocabulary (which and how many words) and creating the best conditions for the acquisition process. This article sets out to ________a computer assisted word acquisition programme (CAVOCA) which tries to do exactly this: the programme operationalises current theoretical thinking about word acquisition, and its ________ are based on a systematic list of the vocabulary relevant for the target group. To ________its frequency, the programme was ________ in a number of experimental settings with a paired associated method of learning new words. The experimental results suggest that an approach combining the two methods is most advisable.

7 . In the sport of track and field, athletes compete not only with one another but against themselves to achieve a new personal best. Aiming to ______ his own record, Cerveny pushed himself hard. However, his legs cramped(抽筋)and ______   him with only 200 meters to go. Determined to ______, Cerveny rose from the ground and continued on, only to fall again after another 50 meters.

______, his coach asked Cerveny if he wanted to stop. He didn't. With great ______ Cerveny pulled himself up and with a(n)   ______ pace, moved forward for one final push. ______, it wasn't enough. 100 meters from the finish line, his legs simply ______ .

Before his coach could ______ him, another runner- Brandon-was at his side to help. His first attempt to get Cerveny up failed, but he   ______ to quit too. With a second pull, Cerveny was ______. At a measured jog, the two completed the final 100 meters of the course, with Cerveny holding Brandon for ______ Brandon even made sure Cerveny crossed the finish line first,securing his______a faster time

In today’s ______ world in which the emphasis in athletics is so often put on breaking records, it was ______ to see that for an athlete like Brandon, the value of true sportsmanship still had legs.

9 . Scientific discovery is popularly believed to result from the sheer genius of such intellectual stars as naturalist Charles Darwin and theoretical physicist Albert Einstein. Our view of such unique contributions to science often _________ the person’s prior experience and the efforts of their lesser-known predecessors (前任者).

_________ such greats as Darwin and Einstein—whose remarkable contributions are duly celebrated — we suggest that innovation is more a process of trial and error, where two steps forward may sometimes come with one step back, as well as one or more steps to the right or left. This evolutionary view of human innovation weakens the idea of _________ genius and recognizes the accumulative nature of scientific progress.

Consider one _________ scientist: John Nicholson, a mathematical physicist working in the 1910s who assumed the existence of ‘proto-elements’ in outer space. By combining different numbers of weights of these proto-elements’ atoms, Nicholson could recover the weights of all the elements in the then-known periodic table. These successes are all the more noteworthy given the fact that Nicholson was _________ about the presence of proto-elements: they do not actually exist. Yet, amid his often fanciful theories and wild guesses, Nicholson also _________ a new theory about the structure of atoms. Niels Bohr, the Nobel prize-winning father of modern atomic theory, _________ this interesting idea to come up with his now-famous model of the atom.

What are we to make of this story? We propose that science is constantly _________, much as species of animals do. In biological systems, organisms may display new characteristics that _________ random genetic mutations (变异). In the same way, random or accidental mutations of ideas may help pave the way for __________ in science. __________ mutations prove beneficial, the animal or the scientific theory will continue to thrive and perhaps reproduce.

__________ for this evolutionary view of behavioral innovation comes from many domains. Consider one example of an influential innovation in US horseracing. The so-called ‘acey-deucy’ stirrup (马镫) placement, in which the rider’s foot in his left stirrup is placed as much as 25 centimeters lower than the right, is believed to give important speed advantages when turning on egg-shaped tracks. It was developed by a relatively unknown jockey named Jackie Westrope. Had he __________ the speed advantage that would be provided by riding acey-deucy? No. He suffered a leg injury, which left him unable to fully bend his left knee. His __________ just happened to coincide with enhanced left-hand turning performance.

Plenty of other stories show that fresh advances can arise from error, misadventure, and also pure serendipity — a happy __________. The time seems right for abandoning the naive notions of intelligent design and genius, and for scientifically exploring the true origins of creative behavior.

10 . If you need courage when facing a challenge, learn from Jessica Cox. Born in February 1983 in Sierra Vista, Arizona, Jessica Cox _________her parents. Why? She had no arms. As Cox grew up, her mother _________ that her daughter had the_________to live a normal life by doing things differently.

_________independent at a young age, Cox learned to tie her shoes, get dressed and take a _________.She also got prosthetic(假体的)arms then and used them for 11 years，all the time_________why. Getting called names like “Robot Girl” made her_________and quiet. But at age 14,everything changed.

Cox remembers boarding the bus on the first day of 8th grade with a_________by Eleanor Roosevelt running through her mind. “No one can make you feel inferior(卑微的) without your_________.”She decided to embrace her__________and removed her prosthetic arms for good. Cox says that it is not until we are__________to ourselves that we are able to overcome our challenges. That year, she also __________her black belt from the International Taekwondo Federation!

After college, Cox was__________ by Arizona Daily Star, which kick-started her career. She has spoken to audiences in over 26 countries since then. Cox often__________people through humor.

Cox conquered her greatest fear-flying-and in 2011 became the world’s first armless pilot. She uses her feet to fly the plane!__________learn from Jessica Cox - challenges are opportunities.
