[单项选择] Some people would say that the Englishman’’s home is no longer his castle; that it has become his workshop. This is partly because the average Englishman is keen on working with his hands and partly because he feels, for one reason or another, that he must do for himself many household jobs for which, some years ago, he would have hired professional help. The main reason for this is a financial one: the high cost of labor has meant that builders’’ and decorators’’ costs have reached a level which makes them so high that the house-proud English people of modest means hang back. So, if they wish to keep their houses looking bright and smart, they have to deal with some of the repairs and decorating themselves.

[填空题]John McEnroe:
I have been using the Internet since the late 80’s when the Internet was called ARPANET and this is the first year I actually did some Christmas shopping on the Internet. I could not find several items for my child’s Christmas gifts so I decided to look online. Normally when I shop in real stores I go in, find what I want and get out (my wife hates this because she wants to look at EVERYTHING). The Internet allows you to go shopping without any fuss or having to wait in line.
