Despite the considerable progress made during the last decade, numerous fundamental questions related to this key process in plant development are outstanding. Numerous models have been proposed through the years to explain the detailed molecular events of cellulose biosynthesis. Almost all models integrate solid experimental data with hypotheses on several of the steps involved in the process. Speculative models are most useful to stimulate further research investigations and bring new exciting ideas to the field. However, it is important to keep their hypothetical nature in mind and be aware of the risk that some undemonstrated hypotheses may progressively become admitted. In this review, we discuss the different steps required for cellulose formation and crystallization, and highlight the most important specific aspects that are supported by solid experimental data.展开更多

文摘The present research reports a comparative study on the use of ＂really＂ by Chinese EFL learners. Taking the perspectives colligation and collocation, the study mainly yields the following findings： （1） Compared with American native speakers, Chinese EFL learners have different preferences for colligations and collocations of ＂really＂; （2） High achievers and low achievers demonstrate a similar pattern of the ranking order of the colligations, but high achievers are closer to the native speakers in the use of ＂really＂ in terms of collocation; low achievers rely more heavily on ＂very＂ to collocate with adjectives than high achievers.
