GRE逻辑题中有黑体题，对考生来说不容易解决。下面，小编为大家分享了GRE逻辑黑体题解题技巧视频讲解，帮助大家解决这个难题。
黑体部分的作用
黑体部分作用题是把论证段落中的一个或两个句子变成黑体，然后问黑体部分在段落推理中的作用。
关键词
1. Since, because, as , for, if, when, whenever, even thugh, it is true that…, show that…是原因，选项中常出现evidence，explanation，based，consideration等词;
2. It shows等等是例证，选项中常出现based…，finding，in support of,evidence等词;
3. However， Consequently，obviously, clearly, hence, therefore, thus…前面就是作者challenge，disagree, call into question的东西，后面是作者support的东西，可能是全文的conclusion，position等等;
4. Therefore，argue that…, conclude, assert that, think that, claim, position, it can be made that…选项中一般出现的是conclusion。
Examples:
1. 美国某杂志减少了国际时事文章的比例。编辑的理由是：“国际时事比例高，杂志的销量就下降，这表明读者不喜欢国际时事文章。”而评论家认为编辑的理由站不住脚，他们认为：“编辑应当引导读者的兴趣而不是迎合读者的喜好。”
解析：后一句黑体是用来反驳上一句黑体部分。
2. 由于人们过量的捕捉X鱼，所以X鱼的数量急剧减少，但渔业部门认为不需要采取防止该鱼灭绝的保护措施。他的基本理由是当鱼减少到一定程度，就会很难捕捉以致经济上不再合算，因此，捕鱼人也就不会再捕捉该鱼。但有人反驳说，该鱼越少越珍贵，捕捉该鱼的人也就越多;而且该鱼少到捕捉已经不合算的地步时该鱼的灭绝就无法挽救了。
解析：后一句黑体是用来反驳上一句黑体部分。
Examples：
Although measuring the productivity of outside consultants is a complex endeavor. Company K, which relies heavily on consultants for long-term projects, must find ways to assess the performance of these workers. The risks to a company that does not review the productivity of its human resources are simply too great. Last year, Company L was forced into receivership after its productivity declined for the third straight quarter.
The bolded phrases play which of the following roles in the argument above?
A. The first phrase states the author’s conclusion, and the second phrase refutes that conclusion.
B. The first phrase states an assumption of the argument, and the second phrase provides evidence to undermine that position.
C. The first phrase states one of the author’s premises, and the second phrase provides the argument’s conclusion.
D. The first phrase states a position, and the second phrase refutes that conclusion.
E. The first phrase states the conclusion, and the second phrase supports the conclusion with an analogy.
问题问的是黑体起的是什么作用。从题目中我们可以看出后一句的黑体部分是对前面黑体部分的举例支持。所以答案选E。
