American cities are similar to other cities around the world: In every country, cities reflect the values of the culture. American cities are changing, just as American society is changing.
After World War U , the population of most large American cities decreased ; however, the population in many Sun Belt cities increased. 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 (居民) became wealthier. They had more children so they needed more space. 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 cities. They prefer the cities to the suburbs because their jobs are there; or they just enjoy the excitement and possibilities 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 renting, In the 1950s, many poor people did not have enough money 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 though 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.

We can conclude from the text that（　）.

A:American cities are changing far the worse B:people have different views on American cities C:many people are now moving from American cities D:the population is decreasing in older American cities

Passage One
Most people want to work, but it has become more difficult in today’ s world to find work for everybody. The economies(经济) of the world need to grow by 4% each year just to keep the old number of jobs for people. Often this is not possible, and so more people are out of work (失业). Some people have no jobs now because new machines can do the work of many people in a short time. Also, machines do not ask for more money and longer holiday. In all of the countries of the world, machines are taking work from people, not only in factories but also on the farms. One machine can often do the work of forty people. About 75 000 people are moving to the cities a day to look for jobs, but only 70% of them can find jobs.

Which of the following is NOT true（）

A:Machines are taking work instead of people. B:Now more people are out of work. C:Machines need more money and longer holidays. D:Most people want to have jobs.

Choice, we are given to believe, is a right. In daily life, people have come to expect endless situations about which they are required to make decisions one way or another. In the main, these are just irksome moments at work which demand some extra energy or brainpower, or during lunch breaks like choosing which type of coffee to order or indeed which coffee shop to go to.
But sometimes selecting one option as opposed to another can have serious or lifelong repercussions. More complex decision-making is then either avoided, postponed, or put into the hands of the army of professionals, lifestyle coaches, lawyers, advisors, and the like, waiting to lighten the emotional burden for a fee. But for a good many people in the world, in rich and poor countries, choice is a luxury, not a right. And for those who think they are exercising their right to make choices, the whole system is merely an illusion, created by companies and advertisers wanting to sell their wares.
The main impact of endless choice in people’s lives is anxiety. Buying something as basic as a coffee pot is not exactly simple. Easy access to a wide range of consumer goods induces a sense of powerlessness, even paralysis, in many people, ending in the shopper giving up and walking away or just buying an unsuitable item that is not really wanted in order to solve the problem and reduce the unease. Recent surveys in the United Kingdom have shown that a sizeable proportion of electrical goods bought per household are not really needed. The advertisers and the shareholders of the manufacturers are, nonetheless, satisfied.
It is not just their availability that is the problem, but the speed with which new versions of products come on the market. Advances in design and production mean that new items are almost ready by the time that goods hit the shelves. Products also need to have a short lifespan so that the public can be persuaded to replace them within a short time. The classic example is computers, which are almost obsolete once they are bought. At first, there were only one or two available from a limited number of manufacturers, but now there are many companies all with not only their own products but different versions of the same machine. This makes selection a problem. Gone are the days when one could just walk with ease into a shop and buy one thing: no choice, no anxiety.
The plethora of choice is not limited to consumer items. With the greater mobility of people around the world, people have more choice about where they want to live and work a fairly recent phenomenon. In the past, nations migrated across huge swathes of the earth in search of food, adventure, and more hospitable environments. Whole nations crossed continents and changed the face of history. So the mobility of people is nothing new. The creation of nation states and borders effectively slowed this process down, but what is different now is the speed at which migration is happening:
How does migration differ from the past

A:People now migrate across the whole earth. B:People now migrate for better life. C:People now have more choice about where to migrate. D:People now migrate for better environment.
