关于电烧伤创面处理原则正确的是
A．保守治疗，清创后采用暴露疗法并积极抗感染
B．早期清创，多次清创直至坏死组织完全清除，延期植皮术，以确保皮片一次成活
C．彻底清除坏死组织，并立即游离植皮一期修复，封闭创面
D．切除所有坏死组织，立即皮瓣一期修复
E．尽可能保存肢体，恢复重建功能
参考答案：D,E
解析：[解题思路] 保守治疗死亡率和并发症发病率高，不宜使用；延期植皮修复缺点清创次数过多，继发性感染造成血管、神经等坏死，截肢率高；创面多较深，损伤严重，深部组织处于缺血状态，单纯游离植皮不易成活。
第二节任务型阅读（共10小题；每小题1分，满分10分） 请认真阅读下列短文，并根据所读内容在文章后表格中的空格里填入最恰当的单词。 注意：每空格1个单词。 When we think about education and language learning, we are most likely to think of books. Although there are lots of language learning methods, many people still prefer to learn only by using books. So what are the advantages of learning a language from a book? Here are its advantages: firstly, you can take language books wherever you go conveniently and you can use them whenever you want. Secondly, they are easy to follow because the courses in them are usually planned for you in strict order starting from the most basic concepts to the more complex. Thirdly, if you are unsure of something, you can continue to work on it as quickly as you like. Lastly, books are likely to have a lot of vocabulary and a lot of topics so you will get great value out of a book with lots of materials in it. Using books to study a language has disadvantages, too. All textbooks and dictionaries usually include some kind of pronunciation guide. These are helpful when there is no other way to learn, but this can't help you practice your pronunciation. With an audio method, you can compare your pronunciation to that of a native speaker. Besides, some words are spoken faster in one sentence or slower in another, so the pronunciation of a word may change according to the emotion or feeling you want to convey. Also, books can’t actually help you hear the language with its unique rhythms spoken by native speakers. With an audio language learning method, you will be able to hear and understand the language better. Therefore, if you can supplemental（补充）your book with some other language tools, such as audio tapes, internet radio or resources such as music or television, you will have a much better chance of understanding the books' pronunciation guide and using it to get a good grasp of the spoken language.
