过渡句:There are two independent variables—availability of alternatives and ease of changing suppliers—that companies should use to evaluate the feasibility of{ subjecting suppliers of indirect purchases to competitive scrutiny}. This can create four possible situations.
{ subjecting suppliers of indirect purchases to competitive scrutiny}是一个策略,用两个变量四种情况来评估这一个策略的可行性。
CDE产生混淆起初,判断错误causing damage是应该是主干还是从句,显然应该是结果,所以排除C。 主干是weather changes, 自然就是指heavy rain 而不是flooding.
看到选项C的时候是有困惑的,但仔细考虑了下this可以指evidence, 跟选项E相同,但是C,E的主要区别在于C是状语,而E是定语,显然后面的部分是形容evidence比形容动词recovered更好。
这题真是醉了,但是也花了些时间是因为不敢相信怎么会有这么没有限制条件的简单题啊
must divide n的意思是说,不管n是几 都能整除,所以这个n不能往大了猜,只有能被最小可能的n整出,才能被n的倍数整出,所以其实问的是最小可能的n是几 ,而n最大的因数是自己
第二个应该是Q/P吧
C很绝啊,堵死了所有否定壁画不对的可能性-----驼峰压根儿就不能形成化石
Like brown bears and polar bears, sloth bears may have evolved in an environment with few trees. 跟treeless还是有区别的,而且是一个进化的过程。相比起来A更加准确直接能从原文找到:Like brown bears and polar bears (and unlike other myrmecophagous mammals, which are noted for their passivity), sloth bears are easily provoked to aggression.
而对于B来说,是补充进来了新的information,排除了另一个可能的因素,所以最有力地支持了
仔细思考一下C:不管人们知不知道会价格上升,就算是提前囤货,这也说明销售总量是受price影响的,所以这个是无关的因素。因为不论知不知道,结论都是成立的。
考点:平行;比较
语义:高保真camera are able to capture material (具有某种程度的保真度相比35-millimeter film 的保真度).. and to protect...
语法:
BD选项:不满足to capture ...and to protect...的合理平行结构。排除
A选项:不是比较两者的保真度。排除
E选项:相比C强调名词而不是一整个句子,结构上不清晰.排除(不确定)
A只是用半导体行业来举例子!!!
两件事情同时发生 寻找其中的因果关系
A coincide with B
主要考点:主谓一致;伴随状语表修饰;for doing 和 to do的区别;代词指代
语义:蟋蟀叫声次数因周围温度变化而变化,叫声次数可以被当作温度计看待
AC选项:主谓不一致。排除
BE选项:in fact possibly serving做伴随状语,由于伴随状语表示结果时应该是一种自然而然的结果,此处不符合。排除
考点:逻辑意思;动名词和名词的区别
语义:一个研究的结果表明海洋生物suffering由于食物链变坏
语法:
ACE选项:increasing强调过程,increase强调结果。根据句意应该是食物链变坏是由海水温度上升这一结果导致的。排除
D选项:强调suffering的原因是food supplies( that were dwindling),排除。
相比之下,B选项强调的是suffering的原因是food supplies were dwindling这一整个事件。句意合理。
Gurney also found that though ilmenites did not form in the diamond-stability field, there was a link useful for prospectors: when the iron in ilmenite was highly oxidized, its source pipe rarely contained any diamonds.同义改写
here was a link useful for prospectors: when the iron in ilmenite was highly oxidized, its source pipe rarely contained any diamonds. He reasoned that iron took on more or less oxygen in response to conditions in the kimberlitic magma itself—mainly in response to heat and the available oxygen. When iron became highly oxidized, so did diamonds; that is, they vaporized into carbon dioxide. 氧化程度判定钻石含量是他们在挖掘中发现的另一个有用途径,而不是G10和其他garnet的差别
思路:为了减少吸烟引起的疾病,政府打算在未来五年把香烟中尼古丁含量减半,不幸的是,对尼古丁上瘾者会为了应对尼古丁量减少而吸更多的香烟----问:文中信息支持/加强了选项哪个预测----烟量变大了,自然焦油tar的平均吸入量只增不减====这个应该属于if it is true 的题型
E中谁的number,这个独立主格没有表示明白,所以跟前一句的联系不明显
