A young man named Charles Lyell had different ideas. He wrote a book about them called Principles of Geology. The earth, according to Lyell, was not only thousands of years old, it was millions of years old. As to (关于) the common belief that changes in the earth"s surface happen suddenly because of a single earthquake or flood, he said that this might happen once in a while, but usually these changes took place very slowly. He believed that the surface of the earth had been changing from the beginning of time. The changes, he said, were caused by the long- term action of the winds and seas, and by forces such as volcanoes breaking out under the earth"s surface. Once in a great while he thought, a mountain might appear for the first time after an earthquake. But usually mountains would rise slowly and steadily. Professor Henslow was interested in Lyell"s ideas, but he did not actually believe them. Charles Darwin could not make up his mind about them. But they set him thinking along lines which would later change the beliefs of thoughtful people all over the world. At Cambridge ,Charles Darwin studied just enough to pass the examination, and received his college degree in 1831. During this time, he had become more and more interested in geology. At the end of the school year, he went to North Wales with one of his teachers to examine the rock formations (构成) and to search for fossils (化石). Fossils are the remains of ancient living things. They are usually found fixed in rocks in the earth"s crust (地壳). Fossils may be of animals, such as fish, insects, birds, or humans. They may be of plants from tiny leaves to huge trees. When a living creatures dies, it usually decays (腐烂) or is eaten by animals. However, if it sinks into a riverbed or is quickly covered by the blowing sands of a desert storm, the bones are kept up in the earth. Over many years the soft inner parts of a bone disappear, leaving the inside bellow. Water containing mineral enters into the hollow. Slowly the mineral hardens and makes the bone hard and heavy, like stone. |

Most people, when they travel to space, would like to stay in orbit for a few days or more. And this stands to reason, if you"re paying $ 20,000 for your trip to orbit! So in order for tourism to reach its full potential there"s going to be a need for orbital accommodation-or space hotels. What would a space hotel actually be like to visit? Hotels in orbit will offer the services you expect from a hotel-private rooms, meals, bars. But they"ll also offer two unique experiences: impressive views-of Earth and space~ and the endless entertainment of living in zero gravity- including sports and other activities that make use of this. The hotels themselves will vary greatly-from being quite simple in the early days to huge luxury structures at a later date. It"s actually surprising that as later as 1997,very few designs for space hotels were published. This is mainly because those who might be expected to design them haven"t expected lauch costs to come down far enough to make them possible. Lots of people who"ve been to space have described vividly what it"s like to live in zero gravity. There are obviously all sorts of possibilities for dancing, gymnastics, and zero-G sports. Luckily, you don"t need to sleep much living in zero gravity, so you"ll have plenty of time for relaxing by hanging out in a bar with a window looking down at the turning Earth below. Of course all good things have come to an end, unfortunately. And so after a few days you"ll find yourself heading back though you"ll be much more expert at exercising in zero gravity than you were when you arrived. You"ll be thinking how soon you can save up enough to get back up again-or maybe you should change jobs to get to work in an orbiting hotel! |
1. When traveling in space, most people would like to stay in orbit for a few days because ____. |
A. it is expensive to travel in space B. they would find the possible life in other star systems C. they could enjoy the luxury of space hotels D. they want to realise the full potential of tourism |
2. Which of the following is a unique experience that space hotels will offer? |
A. The gravitational pull. B. The special views. C. The relaxation in a bar. D. The space walk. |
3. Which of the following is NOT discussed in the passage? |
A. When was the space traveling made possible? B. What are the unique experiences that space hotels will offer? C. Why were there not many published designs for space hotels? D. How can the travelers enjoy themselves in space hotels? |
4. This passage is mainly about ____. |
A. traveling in space B. the ways of living in space hotels C. zero gravity and space hotels D. the description of space hotels |

A common concern we often hear with regard to single children is whether one child necessarily means a lonely child. Many single-child parents feel a dilemma associated with their decision to have only one child. There are no other children in the family for the child to associate with, and this may lead to the child feeling lonely at times, especially during vacations. Another common argument against having just one child is that an only child may be more spoiled than one with brothers or sisters. Many people believe that a single child will not have learned to negotiate with others, and respect the give-and-take involved in many relationships. Some think this may leave the child less able to interact well with people his or her own age than one who has been raised with brothers or sisters. However, for some single-child parents, particularly those with busy careers, the pressures of giving time and energy to a second child can seem too great,resulting in them electing to have no more children. For other parents, the financial burden of having a second child may be the prime consideration. Still others believe that, ______, the parents can give,and the child can receive, more quality time and attention. This often leads to increased self- respect which, combined with increased independence, can lead to the child being more confident. |

There"s a lot of discussion these days about fit kids. Being fit is a way of saying a personeats well, gets a lot of physical activity (exercise) , and has ahealthy weight. If you"re fit, your body works well, feelsgood, and can do all the things you want to do. Here are four rules to live by, if you"re a kid who wants tobe fit. 1. Eat a variety of foods, especially fruits and vegetables. You may have a favorite food, but the best choice is to eat a variety.If you eat different foods, you"re more likely to get the nutrients your body needs. Taste new foods and old ones you haven"t tried for a while. 2. Drink water and milk most often. When you"re really thirsty, cold water is the No. 1 thirst- quencher. And there"s a reason your school cafeteria offers cartons of milk. Kids need calcium to grow strong bones, and milk is a great source of this mineral. 3. Listen to your body. What does it feel like to be full? When you"re eating, notice how your body feels and when your stomach feels comfortably full. Sometimes, people eat too much because they don"t notice when they need to stop eating. Eating too much can make you feel uncomfortable, and over a period of time, it can lead to _____. 4. Be active. One job you have as a kid-and it"s a fun one-is that you get to figure out which activities you like best. Not everyone loves baseball or soccer. Maybe your passion is karate, or kickball, or dancing. Ask your parents to help you do your favorite activities regularly. Find ways to be active every day.

Why are people interested in eating raw foods or whole foods? One reason is that eating these types of food reduces the risk of acid accumulation in your body. Raw and whole foods are usually digested more efficiently than cooked and refined foods. When we cook foods, we destroy the natural enzymes (酶) that are part of the food in its raw form. These enzymes were intended by nature to help us digest the food. When we consume food without these natural enzymes, our bodies either digest the food improperly or allow too many nutrients to be absorbed into the bloodstream. In both instances, the result is obesity. When too many nutrients are absorbed at once, the body grows fat. Improperly digested food moves slowly through the digestive tract, where it becomes increasingly acidic. To protect its vital organs from this acidic waste, the body changes the acid into fat and stores it safely away from the organs. Processed foods contain chemical elements, which might confuse the appetite mechanism that tells us when we"ve had enough to eat; as a result, people often overeat. Processed foods also upset the digestive cycle. The body will either identify these foods as allergens and then store them safely away from the organs as fat, or the remains of undigested food will become acidic and enter the bloodstream as acid waste, which will stick to the blood vessel walls and block the passage of vital oxygen and nutrients heading for the body"s cells. The body"s metabolism (新陈代谢) becomes inactive, and the result is weight gain and obesity. The accumulation of acid in the digestive tract makes digestion increasingly inefficient. When that happens, even healthy foods can become acidic and the food allergies will become more common. To stop this vicious circle in its tracks, people need to consume food and supplements that will neutralize the acid already accumulated in body. Eating the right types of raw and whole foods can help. It"s also important to restore your enzyme balance. You need to identify and avoid the foods that cause acid accumulation and consume the foods that increase enzyme production. If you truly want to change and help your body heal itself, you need to take an active approach. |
1. It can be inferred from Para. 2 that _______. |
A. foods with natural enzymes help people keep fit B. we"d better be cautious about raw and whole foods C. it is essential for people to protect their vital organs D. giving up cooked and refined foods is a new lifestyle |
2. Processed foods are unhealthy because they _______. |
A. destroy body"s cells B. may lead to obesity C. are difficult to digest D. stop body"s metabolism. |
3. What is the main purpose of this passage? |
A. To warn people of the problem of obesity. B. To advocate eating more raw and whole foods. C. To inform people of the harm of processed foods. D. To tell the differences between raw and processed foods. |
4. What is likely to be talked about following the last paragraph? |
A. Different causes of acid accumulation. B. Correct ways to cook raw foods. C. Suitable types of raw and whole foods. D. Active approaches to avoid acid. |

Naps-short sleeps during the day-may improve memory, experts said recently. New research conducted by brain researcher Avi Karni of the University of Haifa in Israel explores the possibility that naps help lock in sometimes long-term memories. "We still don"t know exactly how memory system works during sleep, but the results of this research suggest it is possible to speed up memory consolidation (巩固)," Karni said. Long-term memory refers to memories that stay with us for years, such as "what" memories-a car accident that happened yesterday-or "how to" memories, such as one"s learned ability to play the pianos. Karni, also one of the authors of the study published in a recent issue of the journal Nature Neuroscience, instructed participants to learn a difficult set of finger games, then divided the study subjects into two groups: one that napped for an hour, and one that didn"t. The people who took an afternoon snooze showed obvious improvement in their performance by that evening. "After a night"s sleep the two groups were at the same level, but the group that slept in the afternoon improved much faster than the group that stayed awake," Karni said. And the study also showed just how much faster a 90-minute nap could help lock in long-term memories. "Daytime sleep can shorten the time "how to" memory weakens and forgetting starts,"Karni said, "Instead of 6 to 8 hours, the brain consolidated the memory during the 90-minute nap." |
1. We can learn from the article that ________. |
A. the new research has discovered the memory process during the sleep B. taking a nap helps improve both long-term and short-term memories C. Karni"s findings are based on comparisons between two groups of participants D. people who take a nap will never forget "how to" skills once they are learned |
2. The underlined word "subjects" in paragraph 3 probably mean________. |
A. the people being tested in the study B. the people carrying out the study C. the topics being discussed in the study D. the areas of knowledge being studied |
3. The text is most probably taken from ________. |
A. a newspaper report B. a library guide C. a project handbook D. a science site |
