1 . According to a Gallup World Poll, 1.1 billion people want to move temporarily to another country in the hope of finding more profitable jobs. An additional 630 million people would like to move abroad permanently.

The global desire to leave home arises from poverty and necessity, but it also grows out of a belief that such mobility is possible. People who hold fast to this universal ________ assume that individuals can and should be feel at home anywhere in the world and that they need not be ________ to any particular place. This view was once regarded as a negative product of the industrialization but is now accepted as central to a(n) ________ economy.

It leads to opportunity and profits, but it also has high ________ costs. According to a long research into the emotions and experiences of immigrants (移民) and migrants, many people who leave home in search of better prospects can’t avoid feeling ________ although few speak openly of the substantial pain of leaving home.

Such tolerance of emotional suffering became common among mobile Americans in the 20th century, and represented a(n) ________ from the past. In the 19th century, Americans of all groups, pioneers, soldiers and the millions of immigrants who streamed into the nation, loudly complained that moving was emotionally ________. Medical journals explored the condition, often referring to it by its clinical name: nostalgia (思乡).

Today, discussions of nostalgia are rare, for the emotion is typically regarded by individuals as an embarrassing block to progress and prosperity. The ________ makes mobility appear misleadingly easy.

Technology also tricks us into thinking that mobility is ________. The comforting vision of ________ offered by technology makes moving seem less consequential, since “one is always just a mouse click or a phone call away”.

But such a claim was ________ optimistic, for homesickness continued to hurt many who migrated. The ________ that phone calls and the Internet provide means that those away from home can know exactly what they are missing the exact moment and how it is happening. It gives the impression that one can be in two places at once but it also highlights the ________ of that assumption.

The persistence of homesickness points to the limitations of the universal philosophy that strengthens so much of our market and society. The idea that we can and should feel at home any place on the globe is based on a worldview that celebrates the independent, mobile individual and takes it for granted that men and women are easily separated from family, from home and from the past. But this view isn’t ________ our emotions, for our attachment to home, although often ________, is strong and enduring.
