American cities are similar to other cities around the world: American cities are changing, just as American society is changing. After World War Two, the population of most large American cities decreased; however, the population in many Sun Belt cities increase. Los Angeles and Houston are cities where population shifts (转移) to and from the city reflect the changing values of American society. In the late 1940s and early 1950s, city residents became weathier. They moved out of their apartments in the city to buy their own homes. They bought houses in the suburbs (郊区).
Now things are changing. The children of the people who left the cities in the 1950s are now adults. Many, unlike their parents, want to live in the cities. They continue to move to Sun Belt cities and older ones of the Northeast and Midwest. Many young professionals are moving back into the city. They prefer the city to the suburbs because their jobs are there; or they just enjoy the excitement and possiblilies that the city offers.
This population shift is bringing problems as well as benefits. Countless poor people must leave their apartments in the city because the owners want to sell the buildings or make apartments for sale instead of for rent. In the 1950s, many poor people did not have enough meney to move to the suburbs; now many of these same people do not have enough money to stay in the cities.
Only a few years ago, people thought that the older American cities were dying. Some city residents now see a bright, new future. Others see only problems and conflicts. One thing is sure:many dying cities are alive again.What does the author think of cities all over the world?

Making greener choices and encouraging healthy lifestyles can promote your health and benefit the environment．Here are some guidelines to follow:
Choose foods thoughtfully
Americans have never had such a variety or abundance of food to choose from．Besides so many choice
s, we now hear about our "food print", the amount of land needed to supply o
ne person's nutritional needs for a year．Do we buy cherry tomatoes from Mexico or tomatoes grown locally in a hothouse? Do．we get the Granny Smiths from the fanners' market or the supermarket? Is organic produce healthier for us and the planet?
These are very complex issues that require analysis of many criteria, including the energy used in producing and transporting the food, as well as the type of soil and methods of raising the food．
Despite the complexities, there are some general guidelines you can follow．For instance, eat less meat or eat low on the food chain．Your doctor may have recommended you to restrict your consume red meat because of its too much fat content．Beyond that, there are environmental reasons, too. Raise food animals contributes substantially to climate change because a meat-based diet requires more land, energy and water than a plant - based one．
Drinking plenty of fluids is significant during hot weather or when exercising．But is bottled water the way to go? You may not think so when seeing the true costs．Based on a survey, manufacturing the 30 - plus billion plastic water bottles can produce more than 2．5 million tons of carbon dioxide and use here times the amount of water in the bottle．Adding in transportation, the energy used comes to over 50 million barrels of oil equiv
alent （等价物）．Consequently, skip the bottled water and drink tap water, both at home and at restaurants．Additionally, bottled water is not necessarily cleaner than tap.In Paragraph 2 the author puts forward three questions mainly _____．

The United States is one of the few countries in the world that has an official day on which fathers are honored by their children．On the third Sunday in June, fathers all across the United States are given presents, treated to dinner or otherwise made to feel special．
However, the idea for creating a day for children to honor their fathers began in Spokane, Washington．A woman by the name of Sonora Smart Dodd thought of the idea for Father’s Day while listening to a Mother’s Day sermon in 1909．Having been raised by her father, Henry Jackson Smart, after her mother died, Sonora wanted her father to know how special he was to her．It was her father that made all the parental sacrifices（牺牲） and was, in the eyes of his daughter, a selfless and loving man．Sonora’s father was born in June, so she chose to hold the first Father’s Day celebration in Spikane, Washington on the 19th of June, 1910．
In 1924 President Calvin Coolidge declared the third Sunday in June as Father’s Day．Roses are the Father’s Day flowers: red to be worn for a living father and white if the father has died．
When children can’t visit their fathers or take them out to dinner, they send a greeting card．Traditionally, fathers prefer greeting cards that are not too sentimental（伤感的）．Most greeting cards are too special so fathers laugh when they open them．Some give heartfelt thanks for being there whenever the child need Dad． The United States is special in Father’s Day because ______．
| A．many people celebrate the day | B．only America celebrates the day |

There is that great idea that in an information and knowledge based economy, the most important thing for companies is attracting and holding outstanding talented guys．Obviously I will not say that is not important, but in my opinion a successful and groundbreaking company cannot be built just from the collection of high talented people, as a great sports team can't be constructed only by the collection of great players．
It is more important to build teams of people that achieve the goals according to the company's organizational vision．It is necessary to create organizations where everybody （with outstanding talent or not） can develop their best personal capabilities and that these capacities are addressed to achieve the corporate goals and mission．The company efforts must be addressed to design an organizational system that produces and uses talent from everyone in the company．
Trying to get the best from our people through corporate team building policies, establishing a concrete corporate culture and values, making our company a place where people want to work because it is a good place to stay and develop their capacities, is the best way to compete in the knowledge economy．That will keep us out of the obligation to constantly seek for the "best players" and entering in the retribution auctions（拍卖）．
We have to take into account that, nowadays, the real talented and creative people, like to work or engage themselves in projects where they can develop their capacities, they can be involved in the organizational goals and vision, and where they are treated with respect and dignity．Definitively, they want to be happy doing their jobs．And we have to build organizations where they can find that．

The hole in the Earth’s ozone layer(臭氧层) has until now protected Antarctic from the worst effects of global warming, but scientists have warned that as the hole closes up in the next few decades, temperatures on the continent could rise by around 3℃ on average, with melting ice contributing to a global sea level increase of up to 1.4 meters.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around the region. This is because the hole in the ozone layer has increased cold winds in Antarctic, making much of the continent surface colder than usual.
But now that the gases that cause the ozone hole have been banned, scientists expect the hole to repair itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face the full impact of global warming. This means an increase in average air temperatures of around 3℃ and a reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors Antarctic ice sheets, said, “The ice sheets in Antarctic are hundreds of meters thick. But once warm ocean waters start flowing underneath, the ice will begin thinning and could break up very quickly.” Thinning ice sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western Antarctic has already resulted in a 10% rise in global sea level in recent decades.
Johnson believes that international action to reduce global warming is required immediately or it may be too late. “Everything is connected——Antarctic may be a long way away but it is an important part of the Earth’s system,” said Johnson. “It contains 90% of the world’s ice, 70% of the world’s fresh water and that is enough, if it melts completely, to raise sea levels by 63 meters.”
Even in a worse-case situation scientists don’t expect the ice to entirely disappear, but predict that, because of the melting ice sheets, average sea level rise will be around 1.4 meters higher by the end of the century.
The underlined word “paradoxically” (in paragraph 2) most probably means “”.
| A．rapidly | B．generally | C．contradictorily | D．apparently |
What is the effect of the hole in the ozone layer on Antarctic?
| A．It is causing the ice to melt faster. |
| B．It is making much of the continent colder. |
C．It is making the e ffects of global warming in the region worse. |
| D．It is reducing the amount of water in Antarctic. |
What do scientists think is the biggest danger facing Antarctic?
| A．Rising sea levels. | B．Warming sea water temperature. |
| C．Water pollution. | D．Growing ice sheets. |
Which of the following is true according to the passage?
| A．Antarctic is currently experiencing the full effects of global warming. |
| B．The average temperature has increased by 3℃ in recent decades. |
| C．Antarctic contains most of the world’s fresh water. |
| D．Ten percent of Antarctic’s ice has already been lost. |
