The word "OK" is the most frequently spoken all-purpose expression on the planet — and it's turning 176 years old on March 23, 2015. The term was born during a 19th-century abbreviation(縮寫) craze and went on to international fame with its own hand gesture.

Last year, Henry Nass, a 64-year-old retired English teacher, a New Yorker, had spent the last few weeks handing out cards championing "Global OK Day" in advance of the coming anniversary.

"No matter where people are from they use the word 'OK,' but they don't know where it comes from," says Nass. "The problem is because it's just, you know, OK."

The word is OK, perhaps, but its history is definitely better than average. Late etymologist Allen Walker Read traced the two-letter word to 1839, when editors at the Boston Morning Post signed off on articles as “all correct” with a simple word “OK”.

The word made it into print on March 23 of that year, in an article against a rival editor in Providence who had stated wrongly that a band of Bostonians heading to New York would pass through the Rhode Island capital (Providence).

"We said not a word about our team passing 'through the city' of Providence," the Morning Post reported. "O.K. — all correct."

The humor of the Providence-Boston joke has been lost to history — but the word OK took off from there, soon connoting(隱含) agreement, acceptance, averageness, quality or likability.

By 1840, it served as a slogan for President Martin Van Buren's unsuccessful reelection campaign. “Old Kinderhook is OK,” posters stated, a reference to the eighth president's birthplace and his supporters' belief in his satisfactory performance.

1.Why did Henry Nass hand out cards?

A. To let people understand the history of the word “OK”.

B. To call on people to use the word “OK” properly.

C. To appeal to people to celebrate OK Day.

D. To attract people’s attention.

2.What does the author want to convey in Paragraph 4?

A. The history of the word “OK” is known to average people.

B. The history of the word “OK” is unfamiliar to people.

C. People frequently use the word “OK” in history.

D. People are fond of the word “OK” in history.

3.What does the underlined phrase “took off” in Paragraph 7 probably mean?

A. Got off B. Set up

C. Moved off D. Became popular

4.We can learn from the text that Kinderhook is of the eighth American president.

A. the name B. the birthplace

C. the policy D. the belief

Instead of welcoming each other with open paws(爪),the dogs form an instant rivalry(對抗).When the"brothers"find themselves on the main streets of New York City,they have to team up and work together against a cute but criminal(罪惡的) rabbit named Snowball.Snowball and his army of Ex-Pets,who call themselves"the Flushed(激進的) Pets,"want to take revenge(報復(fù)) on all happy-owned pets and their owners.

13.Now it is job hunting season again.The job fairs flood with hundreds and thousands of 2011graduate students.Owing to the global financial crests,most of the graduate students admit that job hunting is not that easy and longer.
It is always a painful process for college students to find jobs.(66)D However,job positions are quite limited.In order to get a job,the candidates should be more competitive than ever before.
A Chinese expert predicted that the job hunting pressure in China,with a rocketing increase in the active labor force,would reach its climax in 2006,Yet,this situation continues in 2010.In order to transfer the human resources that are more than needed or wanted to the less developed areas in China,the government has tried to Launch a series of policies to help release the pressure. (67)E.
(68)F A higher education may be more helpful to find a good job in the future,while the temptation of an exciting job and the strong will of being a"real"adult urge the youth to step into socially early.For example,when an undergraduate mechanical science and technology major at a famous university is preparing for his postgraduate exam,he receives an offer from a  big foreign company one day (69)A Anyway,it is really tough to prepare for the postgraduate examination.
(70)C This is a tough time and everyone should have some shining points to win the employers'favor.As products of universities,college students are expected to be first-rate talents and should step into the excellent group in the society. However,these students may achieve unexpected success in the fields where their professional knowledge functions to its maximization.

A.Most probably,he is so excited that he decides to quit the exam next year.
B.Almost everyone worries about the result of the postgraduate examination.
C."Survival of the fittest."Darwin's evolution theory appears in the personnel market.
D.With many colleges enlarged in recent years,large numbers of graduates need to hunt jobs.
E.What's more,financial support is provided to encourage the graduates to start their own career.
F.To go on with further education or to find a job is one of the hardest decisions for the graduate students to make now.
G.Competition for a job would be fierce as graduates this year will have to join the job hunting group from previous years.

Cheating can happen in a lot of different ways. When people cheat, it’s not fair to other people, like the kids who studied for the test or who were the true winners of a game.

Many people like the action of cheating. It makes difficult things seem easy, like getting all the right answers on the test. But it doesn’t solve the problem of not knowing the material and it won’t help on the next test --- unless the person cheats again.

Some people lose respect for cheaters and think less of them. The cheaters themselves may feel bad because they know they are not really earning that good grade. And, if they get caught cheating, they will be in trouble at school, and maybe at home, too.

Some kids cheat because they’re busy or lazy and they want to get good grades without spending the time studying. Other kids might feel like they can’t pass the test without cheating. Even when there seems to be a “good reason” for cheating, cheating isn’t a good idea.

If you were sick or upset about something the night before and couldn’t study, it would be better to talk with the teacher about this. And if you don’t have enough time to study for a test because of swim practice, you need to talk with your parents about how to balance swimming and school.

A kid who thinks cheating is the only way to pass a test needs to talk with the teacher and his or her parents so they can find some solutions together. Talking about these problems and working them out will feel better than cheating.

1.Some students like cheating mainly because_________.

A. the material in the test is very difficult

B. they want to do better than the others

C. cheating can make hard things seem very easy

D. they have little time to study their lessons

2.The fourth paragraph mainly tells us______.

A. cheating isn’t a good idea

B. why kids cheat in the test

C. some kids can’t pass the test without cheating

D. some kids don’t spend the time studying

3.We can learn from the passage______.

A. cheaters are often thought highly of

B. people show no respect for those who cheat

C. parents whose kids cheat are often in trouble

D. kids cheat in the test because of swim practice

4.In the passage those cheaters are advised to_______.

A. spend more time on school than on sports

B. find good solutions instead of cheating

C. try hard to be intelligent rather than lazy

D. ask their classmates for good methods of study

We already know the fastest, least expensive way to slow climate change: Use less energy. With a little effort, and not much money, most of us could reduce our energy diets by 25 percent or more—doing the Earth a favor while also helping our wallets.

Not long ago, my wife, PJ, and I tried a new diet—not to lose a little weight but to answer an annoying question about climate change. Scientists have reported recently that the world is bending up even faster than predicted only a few years ago, and that the consequences could be severe if we don't keep reducing emissions(排放) of carbon dioxide (CO2 ) and other greenhouse gases that are trapping heat in our atmosphere.

We decided to try an experiment. For one month we recorded our personal emissions of CO2. We wanted to see how much we could cut back, so we went on a strict diet. The average US household(家庭) produces about 150 pounds of CO2 a day by doing common-place things like turning on air-conditioning or driving cars. That's more than twice the European average and almost five times the global average, mostly because Americans drive more and have bigger houses. But how much should we try to reduce?

For an answer, I checked with Tim Flannery, author of The Weather Makers: How Man is Changing the Climate and What it Means for Life on Earth. In his book, he had challenged readers to make deep cuts in personal emissions to keep the world from reaching extremely important tipping points, such as the melting(融化) of the ice sheets in Greenland or West Antarctica. "To stay below that point, we need to reduce CO2 emissions by 80 percent," he said.

Good advice, I thought. I'd opened our bedroom windows to let in the wind. We'd gotten so used to keeping our air-conditioning going around the clock. I'd almost forgotten the windows even opened. We should not let this happen again. It's time for us to change our habits if necessary.

1.Why did the author and his wife try a new diet?

A. To take special kinds of food.

B. To respond to climate change.

C. To lose weight.

D. To improve their health.

2.The underlined words "tipping points" most probably refer to ________.

A. freezing points B. burning points

C. melting points D. boiling points

3.It can be inferred from the passage that ________.

A. it is necessary to keep the air-conditioning on all the time

B. it seems possible for every household to cut emissions of CO2

C. the average US household produces about 3,000 pounds of CO2 a month

D. the average European household produces about 1,000 pounds of CO2 a month
