新概念英语第二册逐句精讲语言点第52课(2)We have just moved into a new house and I have been working hard all morning. I have been trying to get my new room in order. This has not been easy because I own over a thousand books.To make matters worse, the room is rather small, so I have temporarily put my books on the floor. At the moment, they cover every inch of floor space and I actually have to walk on them to get in or out of the room. A short while ago, my sister helped me to carry one of my old bookcases up the stairs. She went into my room and got a big surprise when she saw all those books on the floor. 'This is the prettiest carpet I have ever seen,' she said. She gazed at it for some time then added, 'You don't need bookcases at all. You cansit here in your spare time and read the carpet!'精讲笔记：4、To make matters worse, the room is rather small, so I have temporarily put my books on the floor.更糟糕的是房间还非常小，所以我暂时把书放在了地板上。

1. ... and to mark an important event in my life, as important to my father as coming of age: my first oyster. (Para 5)The father thought that oysters were such a very special dish and that trying oysters for the first time was like "coming of age". This is humour through exaggeration.2. ... and the only emotion was the fear of lost innocence ... (Para 7)For a child, being innocent is usually regarded in the West as a positive quality, so losing innocence in some way can be sad or regretful, even though it is a sign of growing up. Here the writer realized that he had to eat the oyster so he felt the emotion of fear, not about the oyster as such, but about losing innocence. There is a little sadness here as well as humour: Is eating an oyster really that important and is trying the first oyster really losing innocence?3. ... striking a note of compromise for the first time ... (Para 9)To strike a note of something means to speak in a particular manner or tone. Here, the father indicated a compromise or bargain: If the son ate an oyster, he could choose some other food which he liked.4. ... unlike anything I have ever tasted before or since. (Para 13)Before or since refers to before that occasion or since that time.5. ... he raised his glass to me and said, "Cheers!" (Para 13)This is a common way to make a toast on formal occasions. Similar ways to express good wishes when holding a glass of drinks, just before you drink it, include "Good health!" "Good luck!".1. ... it was so highly valued that even taxes were paid in cocoa beans. (Para 1)In different cultures there have been many different ways in which people pay taxes to the rulers. In ancient China, taxes were once paid in corn or grain, in Britain sheep or cattle were used. Here, the Aztecs paid taxes in cocoa beans, which showed how the beans were considered valuable.2. But what accounts for its amazing popularity or even the properties that have made millions of people confess to being chocaholics? (Para 4)Many people admit that they are chocaholics, so the writer asks about the reason why chocolate is so popular and what special characteristics chocolate may have.Chocaholics are people who love chocolate and eat a lot of it. Similar words are workaholic (someone who works compulsively all the time) and shopaholic (someone who is addicted to shopping).3. These chemicals make us feel happy and give us a sense of well-being … (Para 6)A sense of well-being refers to a satisfactory state that someone may feel that they are in. This includes feeling happy, healthy, safe or having enough money.。

After a time,we noticed a snake charmer with two large baskets at theother side of the square, so we went to have a look at him.As soon as he saw us, he picked up a long pipe which was covered with coins and opened one of the baskets. When he began to play a tune, we had our first glimpse of the snake. Itrose out of the basket and began to follow the movements of the pipe. We were very much surprised when the snake charmer suddenly began to play jazz and modern pop songs. The snake, however, continued to 'dance' slowly. It obviously could not tell the difference between Indian music and jazz!精讲笔记：4. When he began to play a tune, we had our first glimpse of the snake.当他开始吹奏一支曲子时，我枘才第一次看到那条蛇。
