Which of the following most logically completes the passage?
Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed. The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases. A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses. Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since ______.
AI 一个电力公司的CEO说,八年前他公司利润的提高在于每一个被聘用的员工,员工们具有很强的能力与技术,他们所创造的财富大于他们的薪水。而现在公司的效益下降了,原因在于现在招聘的员工不比当初,所以公司效益的下降要归罪于人力资源部门。(大体是这个意思) AA 全球能源的conservation不能依靠单个国家为此的sacrifice,而需要通过global leadership 和 cooperation。
阅读:我的第一篇是那个resin的,jj上有,先讲了讲resin是怎么形成的,amber好象是resin化石后的形态,还有resin很容易和gum以及sap混淆,讲了一下它们之间的差别(有题)。下面一段讲的是resin chemical 的方面,主要集中于和insect之间的:resin本来是insect attack plant后出现的这么一种物质,后来进化了,成了不用insect attack就由plant分泌的一种东西,可以招引来insect并把insect困在resin里。后来有的科学家们专门研究,(这部分我记不太清了,有一道题) 题目:1 main idea 2 关于sap的说法哪一个不正确,这一道题我比较确定,选的是sap比resin less abundantly 3科学家做的那个研究,那个描述是正确的,这是一道定位题,在文章最后一部分。
逻辑我是真心的记不住了,回忆出多少就是多少吧 1 newspaper发言人:他说在网络上浏览新闻不应该免费,应该又官方设定一个价格。 又有一个人说了,这个价格不应该是随意设定的,到底要花多少钱应该是由customer根据网络新闻本身的value决定的。 问题是第二个人是根据哪一个点回应第一个人的。选项真心记不住了 2 黑体字 讲的是outsourcing 前两句说了一下什么是outsourcing以及其好处。接着是黑体字,以however开头,说outsourcing可能对公司有opposite影响。下面一句解释了一下为什么,最后一句又是黑体,应该是结论outsourcing不好。选项我只记得我选的一项 两个都是main conclusion。因为我觉得剩下几项都不太对。 3 gwd上的一道题 我粘过来了 Appendicitis (inflammation of the appendix) is potentially fatal; consequently, patients with symptoms strongly suggesting appendicitis almost always have their appendix removed. The appropriate surgery is low-risk but performed unnecessarily in about 20 percent of all cases. A newly developed internal scan for appendicitis is highly accurate, producing two misdiagnoses for every 98 correct diagnoses. Clearly, using this test, doctors can largely avoid unnecessary removals of the appendix without, however, performing any fewer necessary ones than before, since ______.
A. the patients who are correctly diagnosed with this test as not having appendicitis invariably have medical conditions that are much less serious than appendicitis
B. the misdiagnoses produced by this test are always instances of attributing appendicitis to someone who does not, in fact, have it
C. all of the patients who are diagnosed with this test as having appendicitis do, in fact, have appendicitis
D. every patient who is diagnosed with this test as having appendicitis has more than one of the symptoms generally associated with appendicitis
E. the only patients who are misdiagnosed using this test are patients who lack one or more of the symptoms that are generally associated with appendicitis 4. 一个公司一批人department head要退休了,年轻一辈儿中符合要求顶替这些head空缺的只有一半。但是公司既不打算在外面招人,又不打算削减department的数量,还不打算让一个department head负责两个department。所以来年有一些department没有head,since_____________.
