<正>Who doesn’t want to know more about the most adorable animals on the planet?谁不想更多地了解一下这个星球上最可爱的动物呢?1Pandas have huge growth spurts~1Pandas grow from tiny to massive in a few short years. Pink and hairless, panda infants weigh just three to five ounces and have been compared in size to a stick of butter. But within a year, pandas tip the scales at around 100 pounds;fully mature pandas can be up to six feet long 相似文献

The 2011 horoscope has much less stressful astrological aspects than 2010, in fact there are no major aspects between the outer planets. The planet getting most attention in 2011 is the great benefic Jupiter, with a conjunction to Uranus, opposition to Saturn, sextile to Neptune, and a square plus trines to Pluto. So the major themes will be about growth, both material and spiritual. 相似文献

Venus is similar in size and chemical makeup when compared with Earth - and the pair formed about the same time, more than four billion years ago. But that is apparently where the similarities end. According to a year＇s worth of data sent back from the European Space Agency＇s Venus Express orbiter launched in November 2005, the second planet from the sun is nothing like Earth - from its torrid surface to the upper reaches of its acid-laced atmosphere. The bottom line： just be glad you live here. 相似文献

Coaxial liquid-liquid flows were numerically studied in a nesting two-tube system. Calculations were carried out when various exit-lengths （meaning length differences between the two tubes） were used. Numerical results indicated that there exists a certain range of exit-length for the liquid-liquid flows to form stable and smooth interfaces, which requires that the exit-length should roughly be less than 5.6 times the outer tube diameter. In this range, interface instability is effectively restrained and the core fluid shows a phenomenon of die swell. When the exit-length is about 1.6 times the outer tube diameter, the core fluid has the greatest diameter size in the shell fluid. Velocity distributions at the outer tube exit favor formation of a continuous and stable core-shell structure. 相似文献

Solomon Northup was a married man with two children living in New York when he was kidnapped and sold into slavery. Twelve years later, he managed to escape. On returning home, he wrote a story about his experience called Twelve Years a Slave. This has just been made into a film that＇s directed by Steve McQueen and which stars Chiwetel Ejiofor （as Solomon）, Michael Fassbender and Benedict Cumberbatch. Here＇s the incredible and true story of Solomon Northup. 相似文献

Collaborative Filtering (CF) technique has proved to be one of the most successful techniques in recommendation systems in recent years. However, traditional centralized CF system has suffered from its limited scalability as calculation complexity increases rapidly both in time and space when the record in the user database increases. Peer-to-peer (P2P) network has attracted much attention because of its advantage of scalability as an alternative architecture for CF systems. In this paper, authors propose a decentralized CF algorithm, called PipeCF, based on distributed hash table (DHT) method which is the most popular P2P routing algorithm because of its efficiency, scalability, and robustness. Authors also propose two novel approaches: significance refinement (SR) and unanimous amplification (UA), to improve the scalability and prediction accuracy of DHT-based CF algorithm. The experimental data show that our DHT-based CF system has better prediction accuracy, efficiency and scalability than traditiona 相似文献

The questions concerning vocabulary acquisition have been explored for years.Among all these researches,there is a basic assumption that learners can acquire words from incidental exposure to written texts.Quite a number of empirical studies have testified the hypothesis,in which,the relationship between reading tasks and incidental vocabulary acquisition(IVA) has become an interest in the field of second language acquisition(SLA) studies.The present study presents some theories and studies about the positive effects of reading tasks on IVA and suggests future research on the related topics. 相似文献

There are two different types of oils—high-wax oil and normal oil—found in the Damintun Depression of Liaohe Oilfield after several years of exploration and development, but their distributions and origins had confused the explorers in the oilfield. The introduction of petroleum-system concept shifts the view of geoscientists from geology and geophysics to oil, gas and their related source rocks. After detailed study, two petroleum systems have been identified in the Damintun Depression: (1) the ES42-Ar buried hill petroleum system (called the high-wax oil petroleum system) and (2) the ES41 ES34-ES4 and ES3 petroleum system (called the normal oil petroleum system). Based on the detailed analysis of the basic components, and all the geological processes required to create these elements of the two petroleum systems, it is put forward that targets for future exploration should include the area near Dongshenpu-Xinglongpu and the area near the Anfutun Sag. This provides scientific basis and has theoretical and practical meaning for the exploration and development. 相似文献

While China has certainly taken a great stride in English teaching and learning since its open policy about 30 years ago, there＇s no denying the fact that a lot of concomitant problems occur during its development. This paper explores into two of the hot issues nowadays, and presents the author＇s own experiences in two strikingly different classrooms in China and the United States, and hence some reflections on how to be rational in utilizing multi-media aids as well as research on basic theories. 相似文献

A questionnaire assessing attitudes toward small‐group teaching (SGT) was administered to 442 elementary and secondary school teachers from 26 randomly selected schools in Israel. Data was collected on teachers’ prior experience with SGT, their knowledge of the basic characteristics of this approach and their perception of colleagues’ support for the use of innovative teaching techniques. Teachers expressed somewhat negative attitudes toward SGT on a scale dealing with teacher control of the class, but they were distinctly positive on a scale about the efficiency of SGT for presenting subject matter, and most positive regarding the effect of SGT on pupil development. Teachers experienced with SGT were more positive on 2 out of 3 attitude scales than were those with no experience. Data from measures of teachers’ understanding of SGT characteristics, their perception of colleagual support for innovative teaching and prior experience with SGT accounted for 30 per cent of the variance (canonical R = 0.55) in their responses to the three attitude scales. Findings were discussed in terms of their implications for a model of instructional innovation. 相似文献

ABSTRACTToo often, because of the static nature of schools and the dominant existence of high-stakes testing, professional learning for teachers is determined by administrators or policy and is facilitated by those who are not part of the school community using prepackaged programs. These initiatives run counter to authentic teacher inquiry where teachers enhance their understanding of students and learning and, ideally, develop new teaching practices (Borko, 2004; Cochran-Smith & Lytle, 1999, 2009; Darling-Hammond, 1997). In this article, we focus on how teachers participating in action research begin to position themselves as teacher leaders. 相似文献
