题型:名词解释

阅读理解。

     As you move around your home, take a good look at the things you have. It is likely that your

living room will have a television set and a video, and your kitchen a washing machine and a microwave

oven. Your bedroom drawers will be filled with almost three times as many clothes as you need. You

almost certainly own a car and possibly a home computer, holiday abroad at least once a year and eat

out at least once a week.

      Now, perhaps, more than ever before, people are wondering what life is all about, and what it is for.

Seeking material success is beginning to trouble large numbers of people around the world. They feel that

the long hours work culture to make more money is eating up their lives, leaving them very little time or

energy for family or pastimes. Many are turning to other ways of living and downshifting is one of them.

Six percent of workers in Britain took the decision to downshift last year.

      One couple who downshifted is Daniel and Liz. They used to work in central London. He was a newspaper reporter and she used to work for an international bank. They would go to work by train every day

from their large house in the suburbs, leaving their two children with a nanny. Most evenings Daniel wouldn't get home until eight or nine o'clock and nearly twice a month he would have to fly to New York for

meetings. They both earned a large amount of money but began to feel that life was passing them by.

      Nowadays, they run a farm in the mountains of Wales. "I always wanted to have a farm then," says

Daniel, "and we took almost a year to make the decision to downshift. It's taken some getting used to,

but it's been worth it. We have to think twice now about spending money on car repairs and we no longer have any holidays. However, I think it's made us stronger as a family, and the children are a lot happier.

      Liz, however, is not quite sure. "I used to enjoy my job, even though it was hard work and long hours. I'm not really a country girl, but I suppose I'm gradually getting used to looking after the animals. One thing I do like, though, is being able to see more of my children. My advice for other people wanting to do the

same is not to think about it too much or you might not do it at all."

A.people seldom work long hours to make money

B.people hardly buy more things than necessary

3.Daniel and Liz both agree that the move to the farm ____.

A.was easy to organize

4.What does the author mean by saying"the long hours work culture to make more money is eating up their lives" in the second paragraph ?

A.People work long hours to earn their living.

B.To make more money through hard work is the aim of people's life.

阅读下面短文,回答26-30题。
第一步就是明确爱是一种艺术,正如生活是一种艺术一样。 (①) 我们想知道如何爱, (②) 必须遵循我们学习其他任何艺术的同样方法,诸如学习音乐、绘画、木工或医学技艺及工程艺术的方法。
在学习任何一种艺术时,必要的步骤是什么呢
学习任何一种艺术的过程都能够适当地分为两个方面:一方面精通那门艺术的理论,另一方面熟悉那门艺术的实践。如果我想学习医学技艺,我必须首先了解人体结构和各种疾病,但当我具备了这一方面的全部理论知识时.根本不意味着我在医学技艺上是合格的。只有在大量实践的基础上,把我们的理论知识成果和我们的实践成果融为一体,即变为我的直觉——这是任何一门艺术的要素——之后,我在技艺上才变得精湛起来。当然除学习那门艺术的理论和实践外,为驾驭任何一门艺术,第三点也是必要的要素,即要使艺术精湛必须极其关心这一问题,在我的心中必须是:没有什么比此艺术更重要的事情。
这适用于音乐、医学、木工和爱的艺术。这里有着为什么在当代的文明中,人们很少尝试探究爱这门艺术的答案,尽管他们明显地失败,尽管他们对爱如饥似渴,但却又认为几乎每一件事都比爱重要:成就、名望、金钱、权利——几乎人们的所有精力都被用来研究如何实现这些目标,难怪乎没有谁来学习爱的艺术。
