　　The cells of a plant'are organized into three tissue systems: dermal,vascular, and ground tissue. Each tissue system is continuous throughout theplant's body. The specific characteristics of each tissue, however, are different in the different organs ofthe plant.

　　The dermal tissue system is the "skin" of the plant. The dermal system, or epidermis,is a single layer of cells covering the entire body of the plant. The mailn function of the epidermis is to protect the plant. The epidermis also has specialized characteristics for the particular organs it covers. For example, the epidermis ofleaves and stems has a waxy coating that helps the plant conserve water, and the epidermal cells near the tips of the　plant's roots help the plant absorb water and nutrients from the soil.

　　The second tissue system-the vascular system-is the transportation system for water and nutrients. Vascular tissue also helps to support the plant's structure. The third system- the ground tissue-makes up the bulk of a plant, filling all of the spaces between the dermal and vascular tissue systems. Ground tissue functions in photosynthesis, storage, and support.

托福阅读之植物细胞组成的延伸阅读——托福阅读一次通过秘诀

 

　　1 ，快速阅读：

　　平时进行大量的快速阅读。

　　可选的阅读材料有：时间，“新闻周刊”，经济学家，中国日报，21世纪等。

　　因为托福考试与时代紧密相连，具有一定的时效性，所以报刊文章为泛读的首选。阅读报刊文章应选择一般性的题材，如科普，社会问题，学术观点性的文章，而政治，军事，尖端科技的文章可以略过。采取的阅读方式为快速阅读。

　　2 ，难句突破：

　　在精读和做托福试题时，将复杂的难句摘抄出来，然后分析句子结构，彻底消化难点。虽然托福阅读中不可能有原句重现，但是难句的结构是基本不变的。

　　3 ，词汇强记：

　　词汇量不够，应进行词汇突击。托福考试的词汇量约为6000~8000词。词汇量小也是导致阅读理解速度慢的重要因素。

　　4 总结技巧：

注意分析阅读理解的套路，总结解题技巧。如果个人复习情况不佳，可以根据自己的实际情况选择合适的辅导班。
