老师，B选项，that引导的非限制性定语从句修饰milky sap，但是that不能引导非限制性定语从句，所以做题时是这么判断的。麻烦老师帮助解析一下！

老师，这个题目的意思是说“海商法有这么一个规定”，应该是“这件事”最终刺激了争端。那么D选项的this为什么不能理解为：前面的“这个事”，或者说“这个情况”刺激了。我记得上课说过，类似于B选项这种it，它不能指代“这件事”。

for machinery is just scrap unless it is organized functionally and supported by appropriate systems of operation and maintenance.

A选项的定位在：The constructivists gain acceptance by misrepresenting（constructivists对于technological determinism的理解） technological determinism: technological determinists are supposed to believe, for example, that machinery imposes appropriate forms of order on society. The alternative to constructivism, in other words, is to view technology as existing outside society, capable of directly influencing skills and work organization.

B实际上是constructivists自己的观点：Technological change is constructed as the outcome of negotiations among interested parties who seek to incorporate their own interests into the design and configuration of the machinery. This position represents the new mainstream called social constructivism.

All progress in industrial technology grows out of a continuing negotiation between technological possibility and human need.工业技术的所有进步都是在技术可能性和人类需求之间不断谈判的结果。

再回到B选项上来，比较容易错误地将它排除的原因就在于on the influence of managers。但我们发现在第二段有一句：Clark believes this possibility has been obscured by the recent sociological fashion, exemplified by Braverman’s analysis, that emphasizes the way machinery reflects social choices. For Braverman, the shape of a technological system is subordinate to the manager’s desire to wrest control of the labor process from the workers. 将以上两句意思进行概括正好就是B选项。

Clark refutes the extremes of the constructivists by both theoretical and empirical arguments.

At the empirical level Clark shows how a change at the telephone exchange from maintenance-intensive electromechanical switches to semielectronic switching systems altered work tasks, skills, training opportunities, administration, and organization of workers.

B 非限制性定语从句，表明一些鱼类，所有这些鱼类的卵孵化需要数月，
C 限制性定语从句，将一些鱼类分成了两类，即：“卵孵化需要数月的鱼”和“卵孵化不需要数月的鱼“两类
根据语意，即然句子要表达的是与silvery minnow这种鱼卵的情况来比较，那么就不可能用可以分成两种情况的鱼来比较，故限制性定语修饰错误，应用非限制性定语，B正确。

A选项both...and...是习惯表达；B选项both...and...引导的平行结构不平行，且hoping没有平行对象，不能和插入语里面的成分平行；C选项having won错误，在分词短语里在having表示先时性，但是won这个动作不可能发生在Perform前面；E选项having错误同C，both...as well as错误同A

This historian assumes that Alessandra had goals and interests different from those of her sons, yet much of the historian's own research reveals that Alessandra acted primarily as a champion of her sons' interests, taking their goals as her own. Thus Alessandra conforms more closely to the anthropologist's notion that personal motivation is embedded in a social context.

c的解释说XXX均不影响感染病菌的幼虫数量的减少而引起的总数量的减少。
但是题目的结论不是so the number of ticks acquiring the bacterium would likely decline——所以总数量会减少嘛。。。

请问老师with结构如何解释进行排除呢？

电脑最多买到尹书记的3倍，假设尹书记买b个，电脑最多买3b个，电脑1500一个，尹书记300一个，现在一共有9100元，问电脑最买几个？（不是一共华妃9100元的定值，别理解错。。。）
1500*3b+300*b=9100

一小时=60*60=3600s

原来用两个逗号隔开的形似插入语的定语从句是算成非限制性定语从句的呀，我一直以为是个插入语，然后插入语可以把两个逗号去掉，所以就可以从that来引导定语从句了，看来之前一直想错了。只有三者平行，或者两个完整句子间的and才能加逗号，不能有目的的在主语和谓语间加逗号，插入语除外

that指代reactions；
不能一概认为that指代最接近的名词，要根据句意

slower是形容词，不能修饰动词，而根据句意，slower修饰的是travel，所以应该用副词，可排除ADE； B选项我个人认为就近原则的排除不太好，因为本题中显然没有考察就近原则，一般考察定语从句的就近原则时，会保持定语从句不变，然后修改定语从句前面的先行词，这里B选项的排除应该是同DE一样，即从句意上来看，后面的这句话显然是在修饰说明ricochet这个动作，所以应该用状语而不是定语。其实B选项which是可以指代到waves的吧，因为一个先行词有两个定语从句，只能一前一后摆放呀，毕老师你看一下

伴随状语的逻辑主语不是应该是主句的主语么，traveling的逻辑主语是geologists，这不对啊。。。求解答
