第二段说高走散率,也就是很多鱼进入率其他附近的河道,三文鱼本身的基因就会被稀释,于是环境适应能力就会下降。
但如果适应了环境,就会对三文鱼健康有好处
题目说三文鱼后代健康会因为基因稀释下降,所以需要他们适应环境,才能变健康。。。。
我在说什么啊。。。
however不一定是反对前面内容
这里只是转折,意思是然而也要注意。。。。的问题
所以就是qualify 限定上句中关于高层管理决策如何影响公司坚持其战略计划的可能性的assertion (论断)
限定:让一个观点更详尽
(1)be geared to(ward) doing sth是固定搭配,表示对某事物加以调节以适合某种需要或达到某种水平或标准,或旨在做某事。 这里的to(ward)是介词,后面要跟动名词
(2)错选a,根据句意a complex修饰的是center,但主语依然是programs,需要复数
(3)句意平行,enhance performance, 不能说enhance preparation, 所以只有enhance和prepare才平行
prepare sb for sth使某人为某事做好准备
preparation for sth为某事做准备
be geared to doing sth不能说是固定搭配吧,是be geared to/toward sth/sb(也存在be geared to do sth),这样记固定搭配不合适,应该是表达be geared to/toward sth时有用gerund代替sth的情况
In short, there are now strong reasons to think that it was erroneous to claim that Algonquian family hunting territories ever were, or were becoming, a kind of private property system.
选了a。 which 引领定语从句, having xxx 是从句的现在分词短语
看全——opinion后面的in是 in...area.
晕了,一开始以为说的是河里有致病菌,所以答案选错了。
主谓一致
bearing traits, v-ing 作定语
(A) so...as to be 是一个idiom;
(D)and(E)中,enough表示的是"threshold",so表达的是一个程度,"Enough" implies a sufficient quantity, above a certain threshold - "I have enough money to by the new laptop." "So" is a qualifier meaning "to such a degree that." For example, "I have so much money that I could buy all of the laptops in the world." It doesn't imply any threshold.
B) 并列成分的判断:using +Web sites/public meetings/and mass mailings,所以并不存在V-ing与noun.并列的问题。A)关系代词一定注意判断谓语动词的形式(have/has). 其他知识点:①"using"/"including"的例外性,②and also在非both and结构下是可接受的,③as well as不能取代and
In fact, in 1970 the SBA explicitly stated that their main goal was to increase the number of minority-owned businesses
(使)加倍;(使)增加一倍 to cause (something) to become two times as great or as many
eg. The program will double the amount of money available to help pay for child care.
形容词位于句首,省略being,作伴随状语
先剔除语法,从语义上自己解读下:
A: with+名词短语,“带着……”的意思,表示“公司带着……选择”;
B:因为这些数字等有(他们意识到的)隐含含义,所以公司……;
C:同B;
D:(因为他们)意识到这些数字等的隐含含义,公司……;
显然“意识到”这个动作作为从句的核心词更能表达逻辑关系。
【转载】Idiom: be geared to/toward sth = 使为…而准备;使为了达到…而作好准备
Parallelism: 1) toward A and B not toward A and B; 2) action noun and gerund (without "the") are not in parallel.
错选C,动词和名词不平行
正确C,错选A
错选E with more than 300 rivers draining into it是独立主格结构,其是holds句的状语。在逻辑上,三百条河流入Baikal应是在描述Siberia's Lake Baikal的性质的,而描述名词的均应该是定语,不能使用状语。

premise是outsourcing ,conclusion是boost profit
要想support的话 就要找出outsouring 和 profit 之间的关系
C表示基本上这些外包公司不会成为将来的对手,排除了削弱profit的可能
E也是有关的,如果外包项目能让高层把精力都用来提高核心业务了,那proft自然会增强
E与C相比更直接,因为E提高核心业务对提高profit更有保障;而成为直接竞争对手,只代表对利润有威胁,而不代表对提高利润有影响。
E中的ideologies other than the humanist tradition on the first six Presidents,原文根本没有论述这个话题。区别于negative aspect(C选项)
