Things soon settled into shape.事情很快有了头绪。】The earth became so violent that it was not clear whether the shape would last or not.地球变得如此剧烈，以致于它能否持续下来还不清楚。【注释：①so… that…如此…以致于…：eg. The words tumbled out so fast that I could barely hear them.话说得那么快，我几乎都听不清。②it was not clear whether the shape would last or not.句中的it是形式主语，真正的主语是whether the shape would last or not.】It exploded loudly with fire and rock. “大爆炸”发生时伴有(艳丽的)火焰和岩石。【注释：explode vt. & vi.使爆炸；爆发explode with anger勃然大怒；explode with laughter哄然大笑；explode into laughte r突然大笑起来；explode into pieces炸得粉碎。如：Many people were injured when the boiler exploded.锅炉爆炸时，许多人受了伤。】They were in time to produce carbon, nitrogen, water vapour and other gases, which were to make the earth’s atmosphere.他们最终形成了碳、氮、水蒸气和其它气体，而这些就构成了地球的大气。【注释：in time (1)迟早, 最后eg.

人教版高中英语必修四(高一版)

高中英语黄金阅读(高一版) 习俗类 (1) In the US, people prefer waiting for a table to sitting with people they don’t know. This means a hostess may not seat a small group until a small table is available, even if a large one is. If you are sitting at a table with people you don’t know, it is impolite to light up a cigarette without asking if it will disturb them. At American restaurants and coffee shops you are usually served tap water before you order. You may find the bread and butter is free, and if you order coffee, you may get a free refill. Most cities and towns have no rules about opening and closing time for stores or restaurants, though they usually do make rules for bars. Especially in large cities, stores may be open 24 hours a day. Serving in restaurants is often large; too large for many people. If you can’t finish your meal but would like to enjoy the food later, ask your waitress or waiter for a “doggie bag”. It may have a picture of a dog on it, but everybody knows you’re taking the food for yourself. Supper and dinner are both words for the evening meal. Some people have “Sunday dinner”. This is an especially big noon meal. Tips are not usually added to the check. They are not included in the price of the meal, either. A tip of about 15% is expected and you should leave it on the table when you leave. In some restaurants, a check is brought on a plate and you put your money there. Then the waiter or waitress brings you your change. 1. Which statement is true? A. American people like sitting with people they don’t know. B. A hostess always seats a small group at a large table. C. American people never sit with people they don’t know. D. American people would not light a cigarette if the people who sit at the same table mind their smoking. 2. What is served before you order? A. bread B. butter C. coffee D. cold water 3. What do American people always do when servings are too large for them? A. They take the food home with a doggie bag for their dogs. B. They leave the food on the table and go away. C. They take the food home with a doggie bag and enjoy the food later. D. They ask the waitress or waiter to keep the food for them. 4. Sunday dinner is_______. A. a dinner in the evening B. A big noon meal C. a big lunch on Sunday D. A supper on Sunday 【答案解析】本文介绍了美国人在外就餐时的风俗习惯。 1. D。细节题。根据第一段及关键句…it is impolite to light up a cigarette without asking if it will disturb them 可知 A、B、C 与原文不相符，同时关键句告诉我们“未

必修4 Unit 1 A STUDENT OF AFRICAN WILDLIFE It is 5:45 am and the sun is just rising over Gombe National Park in East Afri ca. Following Jane's way of studying chimps, our group are all going to visit them in the forest. Jane has studied these families of chimps for many years and helped people understand how much they behave like humans. Watching a family of chi mps wake up is our first activity of the day. This means going back to the place where we left the family sleeping in a tree the night before. Everybody sits and wa its in the shade of the trees while the family begins to wake up and move off. Th en we follow as they wander into the forest. Most of the time, chimps either feed or clean each other as a way of showing love in their family. Jane warns us that our group is going to be very tired and dirty by the afternoon and she is right. Ho wever, the evening makes it all worthwhile. We watch the mother chimp and her b abies play in the tree. Then we see them go to sleep together in their nest for the night. We realize that the bond between members of a chimp family is as strong as in a human family. Nobody before Jane fully understood chimp behaviour. She spent years observi ng and recording their daily activities. Since her childhood she had wanted to work with animals in their own environment. However, this was not easy. When she firs t arrived in Gombe in 1960, it was unusual for a woman to live in the forest. Only after her mother came to help her for the first few months was she allowed to be gin her project. Her work changed the way people think about chimps. For exampl e, one important thing she discovered was that chimps hunt and eat meat. Until th en everyone had thought chimps ate only fruit and nuts. She actually observed chi mps as a group hunting a monkey and then eating it. She also discovered how ch
