阅读理解。

     The easiest way for the English to deal with their social discomfort is to avoid social interaction altogether,

by choosing either leisure (闲暇) activities that can be performed in the privacy of one's own house, or

outdoor activities that follow their interest without direct contact with anyone other than one's own family

members, such as going for a walk, or to the cinema, or shopping.

     In recent survey, over half of all the leisure activities were of this private domestic type, and of the top ten

pastimes, only two-having friends round for a meal or drink, and going to the pub-could be described as

"sociable". The most domestic activities are the most popular: watching TV, listening to the radio, reading,

DIY (Do It Yourself) and gardening. Even when the English are being sociable, the survey findings show that

most of them would much rather entertain a few close friends or relatives in the safety of their own homes

than venture out among strangers.

     In the latest national census survey (人口普查), over half of the entire adult male population had been

DIYing in the four weeks before the census date. Nearly a third of the female population had also been busily

improving their homes, and their work with their gardens was equally obvious: 52 percent of all English males

and 45 percent of females had been out there, cutting branches and weeding grass.

     Even among people claiming to belong to a particular religion, only two percent attend services every

week. The rest of the population can be found every Sunday at their local garden center or DIY superstore.

And when they want a break from caring about their own homes and gardens, they go on trips to visit bigger

and better houses and gardens, such as the stately homes and gardens opened to the public by the National

Trust and the Royal Horticulture Society. Visiting grand country houses always ranks as one of the most

popular national pastimes.
