I was standing in the checkout line behind a woman who looked to be in (21)______60s. When it was her turn to pay, the cashier greeted her by name and asked her how she was doing.
The woman looked down,(22)______(shake) her head and said:“Not so good. My husband just lost job and my son is up to his old tricks again. The truth is, I don‘t know how I‘m going to get through the holidays.‖
Then she gave the cashier food stamps.
My heat ached. I wanted to help but didn‘t know how. (23)____ I offer to pay for her groceries or ask for her husband‘s resume?
As i walked into the parking lot, I saw the woman (24)_______(return) her shopping cart. I remembered something in my purse (25)______ I thought could help her. It wasn‘t a handful of
cash or an offer of a job for her husband, but maybe it would make her life better.
My heart pounded as I approached the woman.
―Excuse me,‖ I said, my voice trembling a bit.―I couldn‘t help overhearing what you said to the cashier. It sounds like you‘re going through a really hard time right now. I‘m so sorry. I‘d like to give you something.‖
I handed her the small card from my purse.
When the woman read the card‘s only two words, she began to cry. And through her tears, she said:―You have no idea (26)____ this means to me.‖
I was a little startled by her reply. (27)_____ (not do) anything like this before, I didn‘t know what kind of reaction I might receive. All left for me (28)______(say) was: ―Oh, Would it be OK to give you a hug?‖
(29)______ we embraced, I walked back to my car -- and began to cry, too.
The words on the card?

A few weeks earlier, a colleague gave me a similar card (30)___encouragement for a project I was working on. When I read the card, I felt a warm glow spread inside of me. Deeply touched, I came home and ordered my own box of You Matter card and started sharing them.
Section B
Directions: Fill in each blank with a proper word chosen from the box. Each word can only be used once. Note that there is one word more than you need.
Most of us learn at primary school that there are seven continents, but the next generation of kids may be adding one more to that list.
According to a recent paper published in the geological society of American journal by a group of researchers, ―Z ealandia‘‘is a new continent that‘s31 beneath the ocean.
Zealandia is 32 to be five million sq km. Most of this massive area is covered by water, but its highest mountains already have their own name:New Zealand.
The small country is the only part of new Z ealandia that isn't under water,but the paper‘s authors want the huge landmass to be 33 worldwide as its own continent.
?The scienti fic value of classifying Zealandia as a continent is much more than just an extra name on a list,‘ the researchers wrote in their paper.
Scientists discovered Zealandia all the way back in 1995, then started 34 research on the area using underwater and satellite mapping 35 . After completing their work,they were finally able to write a report suggesting that Zealandia be named a continent.
But who decided on what is a continent and what isn't? There is ,in fact,no official organization that doessome countries teach that there are six or even five continents. This changes depending on where in the world the school is.
Due to their 36 as a continuous expanse of land, some classify Europe and Asia as the same continent-known as Eurasia. Schools in Russia and parts of Eastern Europe teach this.
And tomaking things even more confusing,France and Greece,as well as some other countries,classify North America and South American as simply America.
This argument over how land is defined has even 37 into outer space. In 2006,the International Astronomical Union(IAU)decided that Pluto was no longer a planet ,met the requirements needed to be called a planet ,76 years after its 38 in 1930,experts argued that it no longer met the requirements needed to called a planet alongside the eight others in our solar system. It was therefore renamed a ―dwarf planet(矮行星)‖,meaning that 39 books, models and museum exhibits all over world had to be 40 .
But will be the world take the same notice of new Zealandia? The best way to tell is to keep an eye on our textbooks.
III .Reading Comprehension
Section A
Directions:For each blank in the following passage there are four words or phrases marked a b and c fill in each blanks with the word or phrase that best fits the context.
Good news for awkward teenagers around the world. As time goes by, you could 41 up like a completely different person.
This comes from the longest running personality study ever 42 by scientists. According to
researchers from the University of Edinburgh in the U.K,our personality changes so much from youth to old age that most people‘s personalities in older age are barely43 compared to their younger selves.
The researchers analyzed results from a study in 1947, which gathered 1,208 teenagers in Scotland aged 14 and asked their teachers to 44 . Their personalities based on six traits(特征)
Now more than six decades later,the University of Edinburgh team has managed to contact 635 of the 45 students,and 174 agreed to have their personalities tested once more.
At an average age of 76.7 years old,the group were asked to 46 themselves on the same six personality traits,then pick a close friend or family member to do the same.
By 47the then-and-now test results,the researchers found that there is hardly a relationship between traits people had as teenagers and those in their older years.
It was ―as if the second tests had been given to48 people,‖ the s tudy‘s researchers wrote in their report,which was published in journal Psychology and Aging.
The results were a surprise because research in the past found personality 49 in people tested from childhood to middle-age,and from middle-age to older age.
As the team explained,our personality appears stable over short intervals-- 50 so throughout adulthood. 51 , the longer the intervals between two tests of personality, the __52the relationship between the two tends to be.
It is clear that more studies are needed to find out what is going on here.but it could be thefirst 53 that is not just our cells that are being 54 throughout life--the way we think ,feel and behave might not be as 55 as we once thought.

(A)
One way people are responding to food safety concerns is by going their own food. However, not everyone live on property with enough space for a private plot. One solution is community gardens, which have become popular worldwide, numbering 1,000 in North America alone. In addition to providing low-cost, delicious food, these public spaces offer cities a range of other benefits.
Community gardens are located in a town or city and tended by local residents. Often, the land is on a vacant lot owned by the city. The site is divided into manageable plots, which may be tended by individuals or by the garden‘s members collectively. Since the land is usually publicly owned, the cost for gardeners to lease it is minimal. In fact, New York City, which is home to more than 750 community gardens tended by more than 20,000 members, charges people just $1 a year to lease a plot. Other costs involve soil, tools, seeds, fencing, and so on. However, because they‘ve shared by many people, indivi dual gardeners pay very little
A community garden can quickly pay off, in terms of delicious fruits vegetables, in addition be beautiful flowers. Excess produce can be sold for a profit at farmers markets. But a garden‘s
benefits don‘t stop there. They als o beautify cities, foster strong relationships among residents, and lower an area‘s crime rate. Award-winning spaces like London‘s Culpeper Community Garden even attract tourists. Beautiful and affordable, community gardens are often described as oases in crowded cities.

A. are concerned about food safety

A busy brain can mean a hungry body. We often seek food after focused mental activity, like preparing for an exam. Researchers think that heavy bouts of thinking drain energy from the brain. Whose capacity to store fuel is very limited.
So the brain, sensing that it may soon require more calories to keep going, apparently stimulates bodily hunger, and even though there has been little in the way of physical movement or caloric expenditure, we eat. This process may partly account for the weight gain so commonly
seen in college students.
Scientists at the University of Alabama at Birmingham and another institution recently experimented with exercise to counter such post-study food binges.
Gary Hunter, an exercise physiologist at U.A.B., oversaw the study, which was published this month in the journal Medicine & Science in Sports & Exercise. Hunter notes that strenuous activity both increases the amount of blood sugar and lactate(乳酸盐) — a byproduct of intense muscle contractions（收缩）—circulating in the blood and augments blood flow to the head. Because the brain uses sugar and lactate as fuel, researchers wondered if the increased flow of fuel-rich blood during exercise could feed an exhausted brain and reduce the urge to overeat.
Thirty--eight healthy college students were invited to U.A.B.‘s exercise lab to report what their favorite pizza was. At a later date, the volunteers returned and spent 20 minutes tackling selections from college and graduate--school entrance exams. Next, half the students sat quietly for 15 minutes, before being given pizza. The rest of the volunteers spent those 15 minutes doing intervals on a treadmill: two minutes of hard running followed by about one minute of walking, repeated five times. Hunter says, that should prompt the release of sugar and lactate into the bloodstream. These students were then allowed to gorge on pizza, too. But by and large, they did not overeat. In fact, the researchers calculated that the exercisers consumed about 25 fewer calories than they did during their baseline session. The non-exercisers, however, consumed about 100 calories more.
The study has limitations, of course. We only looked at lunch, Hunter says; the researchers do not know if the runners consumed extra calories at dinner. They also cannot tell whether other types of exercise would have the same effect as runningalthough Hunter says they suspect that if an activity causes someone to break into a sweat, it should also increase blood sugar and lactate, feeding the brain and weakening hunger‘s call.
63.According to the passage, ____may cause many college students to overeat and gain weight.
A.A lot of energy-consuming mental activities
B.Numerous physical movements or calorie burning
C.Failure to resist the temptation of delicious food
D.Bodily hunger caused by physical growth
64.The underlined word ―counter‖ is closest in meaning to ___.
A.Stimulate
B.Maximize
C.Balance
D.Prevent
65.What can be inferred from the passage?
A.Running is more beneficial than walking.
B.Sweating in exercise can make people hungrier
C.The amount of blood sugar and lactate can affect people‘s appetite.
D.When the brain feels exhausted, people tend to do exercise for relaxation.
66.Which of the following statements is FALSE?
A.Mental activities can make people feel hungry.
B.Physical exercise can make people refreshed and stay hungry.
C.Sugar and lactate can help energize and restore people‘s brain.
D.It‘s uncertain what types of exercise can effectively feed the brain.
Section C
Directions: Read the following passage. Fill in each blank with a proper sentence given in the box. Each sentence can be used only once. Note that there are two more sentences than you need.
Self-talk helps us all
Talking to yourself may seem a little shameful. If you‘ve ever been overheard criticizing yourself for a foolish mistake or practicing a speech, you‘ll know the social problems it can cause.
67
But there‘s no need for embarrassment. Talking to ourselves, whether out loud or silently in our head, is -valuable. Far from being a sign of insanity, self-talk allows us to plan what we are going to do, manage our activities and control our emotions.
For example, take a trip to any preschool and watch a small girl playing with her toys. Your are very likely to hear her talking to herself: offering herself directions and talking about her problems.
68 We do a lot of it when we are young.
As according to the Russian Psychologist Lev Vygotsky, we use private speech to control our actions in the same way that we use public speech to control the behavior of others. As we grow older, we keep this system inside.
Psychological experiments have shown that this so-called inner speech can improve our performance in tasks like telling what other people are thinking. Our words give us an interesting view of our actions. One recent study suggested that self-talk is most effective when we talk to oursel ves in the second person: as ―you‖ rather than ―I‖.
69if you want proof, turn on sports channel. You‘re sure to see an athlete shouting at himself or herself.
Talking to ourselves seems to be a very good way of solving problem and working through ideas. Hearing different points of view means our thoughts can end up in different places, just like a regular dialogue, and might turn out to be one of the keys to human creativity.
Both kinds of self-talk –silent and out loud –seem to bring many different benefits to our thinking. 70 .
IV. Summery Writing
Directions: Read the following passage. Summarize the main idea and the main point(s) of the passage in no more than 60 words. Use your own words as far as possible.
For thousands of years, people have across the oceans to trade, explore, and transport goods. However,not every ship arrives at its port of destination. Weather, war, navigation mistakes, and bad luck have caused many ships to sink to the bottom of the ocean. These shipwrecks, which are estimated to number more than three million, have long fascinated us. In addition to being historically important, they sometimes contain great riches.
Historical research is a key motivator for shipwreck hunters. Ships carrying documents and artifacts can teach us about ancient civilizations and important events. For instance, in 1977 the Pandora, which sank in 791, was discovered off the coast of Australia. The findings from the ship helped us understand the events surrounding the famous mutiny(暴动) on another ship—the Bounty. Another important discovery of the US coast is 1996 is widely believed to be the Queen Ann‘s Revenge, the flagship of the private Blackbeard.
Profit is another motive for shipwreck exploration, as companies use advanced sonar, robots, and retrieval equipment to find treasure ships. One such firm is Odyssey Marine Exploration. The company has found hundreds of ships, including, in 2007, Spanish sailing ship containing 500,000 silver coins. The ship, which sank 200 years ago in the Atlantic Ocean, Carried a treasure estimated to be worth $500 million. Soon after the discovery, a long legal battle over ownership rights tool place between the company and the Spanish government. Cases like these are part of an ongoingdebates about protecting historically important ships from treasure hunters.
