But in spite of the fact that I am in the park so much of the time, I share feelings like those of less frequent visitors: I still ③gasp at the massive granite cliffs of Yosemite Valley; I still inhale deeply to capture the scent of giant sequoias and I still seek the serenity of their groves; I still ④exult in feeling moist sphagnum moss cushioning my feet and squirting water through my toes in the sub-alpine meadows of White Wolf; I am still fascinated by the activities of squirrels, pocket gophers, bears, and nutcrackers; I am still surprised and wonder-struck with new revelations and discoveries; and I still feel I can't adequately describe in words my feelings and sensations of Yosemite or, for that matter, the meaning this place has for me.

不过，尽管我大部分时间都呆在公园里，但我与那些不怎么频频造访的游客的感受是相同的：我仍会惊讶于约塞米蒂峡谷的巨大花岗岩悬崖；我仍会为了闻到巨型红杉的香味而狠狠地吸上一口气，并仍会在红杉林中寻找静谧之处；我仍会在行走于&白狼地区&亚高原草地之际，当潮湿的水苔使我的脚下松松软软并将水渗过我的脚缝之时，为那种感觉而惊喜；我仍会为松鼠、口袋地鼠、狗熊和星鸦的活动而着迷；我仍会对新的发现和探索而感到吃惊和万分惊奇；而且我仍会感到我穷于用言语来表达我对约塞米蒂的感觉和感受，甚至不能表达出这个地方对我的意义所在。

Before treatment,there are abundant microvtlli on the cell surface,many filoplodia on the cell rim,few of endoplasmic reticulums , Golgi complexes and mitochondrions with abnormal structure and lots of free ribosomes in the cytoplasm. The shape of nucleus is irregular with high nuclear-cytoplasmic ratio, many dark pellets of heteromatin and a few of nucleoluses in which there ar...

经1.5×10~2g/L地塞米松处理后，细胞表面微绒毛和丝状伪足显著减少或消失，出现皱褶状和小泡状结构；细胞核形规则，核质比值减小，异染色质团块减少，核仁数目减少、结构致密；细胞质中粗糙型内质网、高尔基体、线粒体数量增多，形态结构典型，游离核糖体减少，这些变化说明地塞米松改变了MGc80-3细胞的超微结构特征，具有明显的诱导分化作用。
