阅读理解 Some expressions in English can be really puzzling. Have a look at the following to see how it challenges your brainpower. Homeric laughter The 'Homer' in this expression is the Greek poet. People laugh differently. Some laugh silently, while others tend to laugh loudly. 'Homeric laughter' refers to laughter of the latter kind. It is at times uncontrollable, and the entire body shakes during the process. This kind of laughter is called Homeric laughter because this is how the gods laughed in Homer's classics. A three-ring circus When you refer to a situation as being a three-ring circus, you are saying that it is a situation of complete confusion. There are so many activities taking place all together that they leave you confused or annoyed. The expression comes from the world of entertainment - the circus. The area where the artists perform their acts is called the 'ring'. In the past, some of the circuses were so grand that they had three acts taking place simultaneously in three different 'rings'. The audience had to decide which 'ring' they wanted to focus on. In the swim (of things) When someone is in the swim of things, the individual is actively participating in the things happening around him, as in 'I've been ill, but soon I'll be back in the swim of thing.' In the world of fishing, fishermen use the word 'swim' to refer to the section of the lake/river where fish can be found in plenty. So, if you are a fisherman and wish to catch a lot offish, where would you be? You would be 'in the swim'. Chickens have come home to roost The word 'roost' refers to the place where birds rest. It could be anything - the branch of a tree, a henhouse, etc. The expression is normally used to mean that the bad things that someone did in the past have come back to bite or upset the individual. In other words, one has to face the consequences of the deeds done in the past. The original form of this 700-year-old expression was 'curses are like chickens; they always come home to roost'. 1. Which of the following can best describe the picture? A. Homeric laughter B. A three-ring circus C. In the swim (of things) D. Chickens have come home to roost 2. What does the underlined word 'simultaneously'(Paragraph 3) mean? A. At the same time. B. Step by step. C. All of a sudden. D. One after another. 3. lf you want to know more about such expressions, which website will you probably visit? A. www.chinadaily.com.cn/sports/China.html B. www.chinadaily.com.cn/world/university.html C. www.chinadaily.com.cn/culuture/language.html D. www.chinadaily.com.cn/entertainment/fashion.html 4.
