Why haven’t I left yet Everyone seems to be asking me this question now. Clearly their having to say goodbye as if it’s the last time they’ re ever going to see me is beginning to wear out my friends. Some of the more unfortunate must have said goodbye at least three or four times. Much to everyone’ s delight, I will be setting off this Saturday, but getting all the necessary visas (签证) for the journey has been far from quick, cheap or straightforward.
Getting a Chinese visa was easy enough. The Mongolian embassy (大使馆) seemed a bit unprepared for me, or in fact any other tourist, wanting to visit the country in winter and it took half an hour of knocking at the door before I got an answer. The Mongolian visa, however, has a map of the country in the background that should come in handy if I get lost out on the grassland.

[单选题]Text 1 Foreign cashiers and carers are now a fact oflife in Japan,especially in urban areas.The number of foreign workers has risen fast recently,t0 1.3m-some 2%of the workforce.Although visas that allow foreigners to settle in Japan are in theory mainly for highly skilled workers,in practice those with fewer skills may be admitted as students or trainees or as immigrants of Japanese extraction.In June the govemment announced that it would create a"designated-skills"visa in order to bring in 500,000 new workers by 2025,in agriculture,construction,hotels,nursing and shipbuilding.Japan has historically been cautious of admitting foreigners.It is one of the rich world's most homogenous countries:just 2%of residents are foreigners,compared with 4%in South Korea and 16%in France.The reasons for this attitude range from fears that outsiders will bring crime and damage societal practices,to concerns that Japanese residents will not be able to communicate properly with them.But Japan's population is old and getting smaller.To fill shortages in the labour force caused by the shrinking working-age population,govemment policy has focused on getting more women and old people into work,and using artificial intelligence.It has become apparent though that this is not enough;and businesses also want foreigners to help them remain competitive and to become more global.Indeed pressure from business is a big reason behind the change of tack.Over the past 20 years the number of workers under 30 has shrunk by a quarter.Another result of the greying population is the creation of ever more jobs,most notably as carers,that few Japanese want to do at the wages on offer.There are 60%more job vacancies than there are people looking for work.Industries such as agriculture and construction,as well as nursing,are increasingly dependent on foreigners.More exposure to foreigners,through a boom in tourism,has reassured Japanese,especially the young,that they can get along with them,too.Attracting the foreign workers Japan needs will not necessarily be easy.Language is a big barrier.Japanese-language abilities are not necessary for highly skilled workers wanting visas,but only a handful of companies work in English.Lowlier workers,who must pass a Japanese exam,are currallowed to bring their families and will not be able to under the"designated-skills"visa.Firms in which promotion is based on seniority rather than merit and in which long hours are the norm will find it hard to attract workers,too.Japan also needs to do more to help integrate foreigners.By accepting,for the most part,a small number of highly skilled workers,Japan has been able to get away without any inteUation policy.But as the number ofimmigrants rises,and especially as more low-skilled workers are admitted,this omission threatens to bring about some of the very concems that prompted the govemment to restrict immigration in the first place,such as ghettoisation and poverty.
According to Paragraph 3,the changes of Japan's attitude may result from the followingently not except_____
A.some specific positions are lack ofwork forces
B.tourist industry promotes contact with foreigners
C.numbers ofyoung workers decreased to some extent
D.some industries need the introduction of foreign technology
