Weather changes when the temperature and the amount of water in the atmosphere change. We can see and feel water coming from the atmosphere when we have rain. But the water must somehow get back to the atmosphere. Meteorologists call this the water cycle. There are many stages in the water cycle. Rain falls when water vapour in clouds condenses(冷却成 液体). Drops of water form and fall to the ground. The water soaks into the ground and feeds streams and rivers. A lot of rain falls into the sea. The heat of the sun evaporates some of the water in the ground and in the rivers, lakes and the sea. It changes the liquid water into water vapour. The vapour rises onto the air. Water vapour is normally invisible. On a very damp or humid day, however, you can sometimes see water vapour rising from a puddle or pond in a mist above the water. Water vapour also gets into the air from living things. Trees and other plants take in water through their roots and give off water vapour from their leaves. People and land animals drink water and breathe out water vapour. In all these ways the water returns to the air. There it gathers to form clouds and condenses to form rain. The rain falls to earth, and the cycle starts again. It contains even if snow or hail fall instead because both eventually melt and form water. The amount of water vapour is more in the air tropics than in the cold polar regions. 1. What is the main idea of the passage? A. Water cycle. B. Water vapour. C. How rain forms. D. Water, vapour, rain. 2. How many ways of the water returning to the air are discussed in the text? A. Three B. Four C. Five D. Six 3. Whether water vapour can be seen or not depends on_____. A. how much water is evaporated B. how good your eyes are C. in which way water is evaporated D. climate or weather 4. From the passage, we get to know_____. A. there is more water vapour in the air tropics than in cold polar regions B. there is more water vapour in the air in cold polar region than in the tropics C. it gets more rain in the tropics than in cold polar regions because there is less vapor D. the amount of water vapour in the air depends on how often it rains |
If English means endless new words, difficult grammar and sometimes strange pronunciation, you are wrong. Haven"t you noticed that you have become smarter since you started to learn a language? According to a new study by a British university, learning a second language can lead to an increase in your brain power. Researchers found that learning other languages changes grey matter. This is the area of the brain which processes information. It is similar to the way that exercise builds muscles. The study also found the effect is greater when the younger people learn a second language. A team led by Dr. Andrea Mechelli, from University College London, took a group of Britons who only spoke English. They were compared with a group of "early bilinguals" who had learnt a second language before the age of five, as well as a number of later learners. Scans showed that grey matter density (密度)in the brain was greater in bilinguals than in people without a second language. But the longer a person waited before mastering a new language, the smaller the difference is. "Our findings suggest that the structure of the brain is changed by the experience of learning a second language," said the scientists. It means that the change itself increases the ability to learn. Professor Dylan Vaughan Jones of the University of Wales, has researched the link between bilingualism and maths skills. "Having two languages gives you two windows in the world and makes the brain more flexible (灵活的)," he said. "You are actually going beyond language and have a better understanding of different ideas." The findings were matched in a study of native Italian speakers who had learned English as a second language between the ages of 2 and 34. Reading, writing, and comprehension were all tested. The results showed that the younger they started to learn, the better they will do it. "Studying a language means you get an entrance to another world," explained the scientists. |
1. The main subject talked about in this passage is________. |
A. science on learning a second language B. man"s ability of learning a second language C. language can help brain power D. language learning and maths study |
2. We may know from the scientific findings that________. |
A. the earlier you start to learn a second language, the greater the grey matter density is B. there is no difference between a later second language learner and one who doesn"t know a second language C. the experience of learning a second language has bad effect on people"s brain D. the ability of learning a second language is changing all the time |
3. In the last two paragraphs,the author wants to tell us that________. |
A. learning a second language is the same as studying maths B. early learning of a second language helps you a great deal in studying other subjects C. Italian is the best choice for you as a second language D. you"d better choose the ages between 2 and 34 to learn a second language |

In 1952, on the island of Koshima(越谷,日本某地), scientists were providing monkeys with sweet potatoes dropped in the sand. The monkey liked the taste of the raw sweet potatoes, but they found the dirt unpleasant. An 18-month-old female named Imo found she could solve the problem by washing the potatoes in a nearby stream. She taught this trick to her mother. Her playmates also learned this new way and they taught their mothers too. This cultural innovation was gradually picked up by various monkeys before the eyes of the scientists. Between 1952 and 1958 all the young monkeys learned to wash the sandy sweet potatoes to make them more palatable(美味的). Only the adults who imitated their children learned this social improvement. Other adults kept eating the dirty sweet potatoes. Let us suppose that when the sun rose one morning there were 99 monkeys on Koshima Island who had learned to wash their sweet potatoes. Let"s further suppose that later that morning, the hundredth monkey learned to wash potatoes. Then it happened. By that evening almost everyone in the tribe was washing sweet potatoes before eating them. The added energy of this hundredth monkey somehow created an ideological breakthrough! But notice: A most surprising thing observed by these scientists was that the habit of washing sweet potatoes then jumped over the sea colonies of monkeys on other islands and the mainland troop of monkeys at Takasakiyama(高岐山)began washing their sweet potatoes. Thus, when a certain critical(关键的)number achieves an awareness, this new awareness may be communicated from mind to mind. Although the exact number may vary, this Hundredth Monkey Phenomenon(现象)means that when only a limited number of people know of a new way, it may remain the conscious property(个人意识性属性)of those people. But there is a point at which if only one more person comes to a new awareness, a field(能量场)is strengthened so that this awareness is picked up by almost everyone! Your awareness is needed. You may be the "hundredth monkey" |
1. The passage may be adapted from __________. |
A. a text book |
2. It was __________ that found the way to make potatoes clean by washing them. |
A. a young clever female monkey B. an old experienced monkey C. an 18-year-old mother monkey D. a monkey finding a potato in the river |
3. The last sentence of Paragraph 1 "This cultural innovation was gradually picked up by various monkeys before the eyes of the scientists." implies that __________. |
A. monkeys have learnt the new way unconsciously(下意识地) B. monkeys like picking up things on the ground C. it is very difficult for monkey to learn a new way D. monkeys learnt the new way from scientists |
4. According to the writer, the hundredth monkey __________. |
A. is the last one to learn to wash potatoes B. is the most stupid in learning C. makes a great difference in spreading a new way D. plays a small part in the breakthrough |
5. The write wrote the last paragraph __________. |
A. to draw a conclusion that one day monkeys will become human beings B. to predict that one day every reader can turn into the hundredth monkey C. to encourage people to learn more knowledge D. to emphasize the importance of each person"s contribution to spreading a new method |
