gre和专八哪个难
GRE考试在英语考试的难度中可以说是还是比较大的，而在国内，英语专业八级考试可以说是非常难的了，有人就会将GRE和专八作比较，究竟哪一种考试难度更大呢?为解决这个疑问，收集整理了一些资料，供大家参考。
gre和专八哪个难
在众多的出国留学的考试中，大家不免就会将这些考试来做比较。比较这些考试所需的词汇量、比较整体考试所需的准备时间等等。都是英语考试，国内的一些考试也是被大家拿出来进行比较。
比如这个问题。GRE和专八哪个难度比较大呢?回答这个问题，需要不少的知识做铺垫，在这里智课妞就为解决这个问题进行相关资料的收集整理，帮助大家对这两种考试有更深入的了解。
GRE和专八难度对比：
都说GRE考试难度高，那么其难度究竟有多高呢?
英语专业八级堪称国内专业英语证书中难度最高的一种，它与GRE相比难度又如何?
下面小编就为大家稍作介绍。
考试形式有本质区别
首先新GRE考试是一门英语考试，但是只是形式上的英语考试，本质上它和其它所有的英语考试有着天壤之别。大家不要忘了新GRE考试是美国研究生入学考试，是为了检验一个本科生有没有能力进入研究生院进行深造。
因此新GRE考试是一种能力的考试，是对一种思考、创新等科研所必须的综合能力的检验，只不过它是美国这样一个英语国家的考试，所以就是所谓的形式上的英语考试。
GRE考试词汇量秒杀专业八级
新GRE考试词汇量要求就要高于英语专八，即使考过英语专八的同学，也要在词汇量方面，进行巩固与加强，才能将新GRE考试拿下。对比新GRE考试难度和专八难度则不好比较，有重点的复习是关键。
看完上文内容，想必大家对于两项考试的难度也有了一定的了解。其实，单纯意义上的难度比拼并没有太大意义，能够考过其中一门考试的人，也不一定就能顺利通过另一门考试，只有踏踏实实地备考复习，才是考生应对GRE考试最好的方法。

GRE阅读题目解析:守窝长尾石龙子
Our study revealed that nest-guarding long-tailed skinks (a species of lizard) homed (returned to their nests) more successfully when displaced shorter distances. There are two reasons why homing success rates decreased with increasing displacement distance. One possibility is that females were simply displaced too far to find their way home. However, this is unlikely given that some individuals managed to find their way home from each distance we used. The second possibility deals with trade-offs between the risks associated with making a long return trip and the benefits of returning. Animals should expend energy only when the associated costs are low. As reptiles increase the time spent moving, their daily energy expenditure increases dramatically. The energetic costs of returning home and the chances that the eggs will have been preyed upon during the return trip both increase substantially as displacement distance increases. For example, the 130 hours (5.5 days) that female skinks spent returning from a distance of 300 meters is sufficient for an egg-eating snake to locate and prey upon the entire clutch. However, females with larger clutches were more likely to home at distances over 50 meters. For these females, the relative fitness benefits associated with having more eggs successfully hatch may outweigh the energetic costs of returning to a nest site, even if the nest may have already been preyed upon.
1. The primary purpose of the passage is to
A. question the validity of research on nest-guarding behavior in long-tailed skinks
B. consider explanations for a finding regarding long-tailed skinks
C. discuss the importance of homing for long-tailed skinks
D. describe the relationship between clutch size and homing success in long-tailed skinks
E. identify the benefits of a behavior common among long-tailed skinks
2. The claim in the highlighted sentence assumes which of the following about the individuals that managed to find their way home from each distance?
A. They were less able to detect egg-eating predators than were the other long-tailed skinks studied.
B. They were more averse to risk than were the other long-tailed skinks studied
C. They expended less energy when homing than did the other long-tailed skinks studied.
D. They did not possess better homing skills than did the other long-tailed skinks studied.
E. They had significantly smaller clutches than did the other long-tailed skinks studied.
3. The "second possibility" implies which of the following as a possible explanation for the female long-tailed skinks that failed to home from distances over 50 meters ?
A. They had relatively small clutches
B. They were unable to find their way home
C. They lacked sufficient energy to home successfully
D. They had male long-tailed skinks guarding their clutches
E. They detected evidence of egg-eating snakes In the vicinity of their nests.

Our study revealed that nest-guarding long-tailed skinks (a species of lizard) homed (returned to their nests) more successfully when displaced shorter distances.
我们的研究显示，守窝长尾石龙子(一种蜥蜴)被移动的距离越短，返家(回窝)成功率越高。
2
There are two reasons why homing success rates decreased with increasing displacement distance.
随移动距离变长回窝成功率变低的原因有二。
3
One possibility is that females were simply displaced too far to find their way home.
一种可能，单纯是因为雌石龙子被移动得太远，找不到家了。
4
However, this is unlikely given that some individuals managed to find their way home from each distance we used.
然而，这不大可能，因为一些个体无论被移动多远，都成功回窝。
5
The second possibility deals with trade-offs between the risks associated with making a long return trip and the benefits of returning.
第二种可能，涉及 在 长途跋涉回家的风险 与 回到的好处 之间权衡利弊。
6
Animals should expend energy only when the associated costs are low.
动物理应在相关代价较低时消耗能量。
7
As reptiles increase the time spent moving, their daily energy expenditure increases dramatically.
因为爬行动物移动慢，它们一整天消耗的能量剧增。
8
The energetic costs of returning home and the chances that the eggs will have been preyed upon during the return trip both increase substantially as displacement distance increases.
随着被移动的距离增加，回窝要消耗的能量，以及在此期间蛋被吃掉的几率都增加了。
9
For example, the 130 hours (5.5 days) that female skinks spent returning from a distance of 300 meters is sufficient for an egg-eating snake to locate and prey upon the entire clutch.
比如说，雌石龙子花 130 小时(5.5 天)跋涉 300 米回窝，已经足够蛇定位以及吃掉所有的蛋。
(clutch 一次产或孵的蛋)
10
However, females with larger clutches were more likely to home at distances over 50 meters.
然而，守着大窝的雌性仍然更可能在被移动超过 50 米的情况下回窝。
11
For these females, the relative fitness benefits associated with having more eggs successfully hatch may outweigh the energetic costs of returning to a nest site, even if the nest may have already been preyed upon.
对于这些雌性来说，让更多蛋成功孵化的相对适应性利益，超过了回窝会消耗的能量，即便蛋可能已经被吃了。
(fitness 最早讲这个概念在 15 / 36 P1，有兴趣的同学去翻
基因适应度，指特定条件下，某个体让自己的基因进入后代基因库的能力，也就是让自己携带的基因尽量延续下去的能力。

1. The primary purpose of the passage is to
A. question the validity of research on nest-guarding behavior in long-tailed skinks
B. consider explanations for a finding regarding long-tailed skinks
C. discuss the importance of homing for long-tailed skinks
D. describe the relationship between clutch size and homing success in long-tailed skinks
E. identify the benefits of a behavior common among long-tailed skinks
选 B
评估 对 一项关于长尾石龙子的观察发现 的多种解释。
finding 就是有的回窝，有的不回。
2. The claim in the highlighted sentence assumes which of the following about the individuals that managed to find their way home from each distance?
A. They were less able to detect egg-eating predators than were the other long-tailed skinks studied.
B. They were more averse to risk than were the other long-tailed skinks studied
C. They expended less energy when homing than did the other long-tailed skinks studied.
D. They did not possess better homing skills than did the other long-tailed skinks studied.
E. They had significantly smaller clutches than did the other long-tailed skinks studied.
选 D
难题。
首先在于问法，即对于那些被移动多远都回窝了的石龙子，这句话隐含了什么假设。
One possibility is that females were simply displaced too far to find their way home. However, this is unlikely given that some individuals managed to find their way home from each distance we used.
不妨把句 3 - 4 连起来看。
句 3 说，一些雌石龙子不回家，单纯是因为找不到路了，to far to find their way home 。句 4 则否认了这种可能 this is unlikely，因为有一些始终要回家，也成功地回了家。
看到这里，如果你足够敏锐，就该意识到这样一种情况：可能有一只，它想回家，但因为找不到路，只能在外面瞎打转干着急。
文中有提到这样的，想回家又回不了的石龙子吗?
没有。
后文提到了两种情况，一种是想了想不回了因为不值(言外之意，想回还是能回的)，一种是想过了无论如何要回也确实回去了。
你注意到了吗，两种情况的区别只在于 trade-offs 对收益与风险的权衡，不在于认路的能力，即文章的作者认为所有石龙子都一样认路，想回家就一定能找到路。
这就是这句话隐含的假设：回家的并不比其他更认路。
现在做完这道题，你认为作者在文中的论证是否存在问题?其结论是否成立?
其实，这道题非常犀利地指出了文章逻辑的不足。作为一项意在考察蜥蜴是否回家的研究，竟然因为有的蜥蜴成功回家，就假设所有蜥蜴都像上帝一样认路。回头再看看，这道题中竟然一个科学家的名字都没出现过，我怀疑这篇 “ 文章 ” 是 ETS 编的，而不是改写的，故意卖个逻辑上的破绽好出题。
3. The "second possibility" implies which of the following as a possible explanation for the female long-tailed skinks that failed to home from distances over 50 meters ?
A. They had relatively small clutches
B. They were unable to find their way home
C. They lacked sufficient energy to home successfully
D. They had male long-tailed skinks guarding their clutches
E. They detected evidence of egg-eating snakes In the vicinity of their nests.
选 A
注意问法，从 “ second possibility ” 出发推断可能的解释。根据句 10 - 11 可选出 A 。其实 B / C / E 都是比较有可能的推测，只是因为文章的逻辑缺陷，三者都得不到表达。
GRE阅读题目解析:河生雌鳚鱼选择巢穴
P44
When selecting a nest, the female of the river blenny (a small fish) appears to be sensitive to both size and orientation. Blennies deposit their eggs preferably in nests under large stones and in nests facing southeast. Southeast-facing nests contain larger egg clutches, a fact that cannot be completely explained by differences in nest stone sizes. Moreover, in a recent study, current speeds upstream of the nest and at the nest entrance were similar for nests facing southeast and those facing in other directions. A southeast-facing entrance per se thus seems to be the specific nest feature preferred by females, rather than the effect of selective positioning on current at nest entrance. The reasons for this preference are unclear, however.
1. The passage is concerned with which of the following
A. Determining the different ways in which current speeds can influence the nesting preferences of female river blennies
B. Establishing nest orientation as a determining factor in egg laying among female river blennies
C. Questioning the importance of nest size as an influence on egg laying among female river blennies
D. Comparing the features of female river blennies that face southeast with those of nests facing in other directions
E. Examining how female river blennies determine the relative importance of nest size versus nest orientation
2. The author of the passage considers “current speeds” in order to
A. identify a factor that undermines the significance of nest stone size for female river blennies
B. indicate one possible advantage of river blenny nests that do not face southeast
C. eliminate a possible explanation for a nest orientation tendency among female river blennies
D. indicate why female river blennies are sensitive to both size and orientation of possible nests
E. suggest a reason why many female blennies prefer southeast-facing nests

When selecting a nest, the female of the river blenny (a small fish) appears to be sensitive to both size and orientation.
选择巢穴时，河生雌鳚鱼(一种小鱼)似乎对大小和朝向都有挑剔。
(
鳚 [blenny]
鲈形目鳚亚目许多种鱼类的统称。大多体型小，海产，广布于热带到寒带海域。体细长如鳗。生活于各种生境，包括岩潭、沙滩、礁盘和藻床。多数生活于浅水，但有些可深至水下450米处。有些主要为草食性，有些则部分或完全为肉食性。一般为底栖，没有多少经济价值。

(https://en.wikipedia.org/wiki/Blennioidei)
)
2
Blennies deposit their eggs preferably in nests under large stones and in nests facing southeast.
鳚鱼更喜欢把卵产在大石下以及朝向东南的巢中。
3
Southeast-facing nests contain larger egg clutches, a fact that cannot be completely explained by differences in nest stone sizes.
产在朝向东南的巢中的卵更大，这无法用巢的大小完全地解释。
4
Moreover, in a recent study, current speeds upstream of the nest and at the nest entrance were similar for nests facing southeast and those facing in other directions.
此外，最近一项研究显示东南朝向与其他朝向，巢受水流冲刷的速度与巢口的水流速度都相近。
(这里翻译不是很确定，坦白一下我的想法。
upstream 逆流的，向上游的
upstream of the nest 我理解为，巢是不动的，upstream of the nest 指水流冲刷巢，也就是那块石头的速度
有不同理解请留言指导我)
5
A southeast-facing entrance per se thus seems to be the specific nest feature preferred by females, rather than the effect of selective positioning on current at nest entrance.
所以，入口西南朝向本身，似乎是雌鱼择巢的特征，而不是因为巢口水流速度而选择巢口的朝向。
6
The reasons for this preference are unclear, however.
然而，这种偏好的原因仍未探明。
1. The passage is concerned with which of the following
A. Determining the different ways in which current speeds can influence the nesting preferences of female river blennies
B. Establishing nest orientation as a determining factor in egg laying among female river blennies
C. Questioning the importance of nest size as an influence on egg laying among female river blennies
D. Comparing the features of female river blennies that face southeast with those of nests facing in other directions
E. Examining how female river blennies determine the relative importance of nest size versus nest orientation
选 B
确定巢的朝向是河生雌性鳚鱼产卵的决定因素。
establish 此处解释为 确定、证实。
A 错。句 5 告诉我们，水流速度没啥区别 similar 。
C 错。文章没有质疑大石偏好，只在句 2 提了一下：Blennies deposit their eggs preferably in nests under large stones and in nests facing southeast.
D 错在 features of female river blennies，没有讨论鱼，只讨论了巢，水流什么的。
E 错。没有比较两种因素哪个更重要。
2. The author of the passage considers “current speeds” in order to
A. identify a factor that undermines the significance of nest stone size for female river blennies
B. indicate one possible advantage of river blenny nests that do not face southeast
C. eliminate a possible explanation for a nest orientation tendency among female river blennies
D. indicate why female river blennies are sensitive to both size and orientation of possible nests
E. suggest a reason why many female blennies prefer southeast-facing nests
选 C
去掉一种可能的解释。
需要读懂整段才能做对：
鱼产卵有两种偏好，大石头，开口朝东南。文段着重讨论了开口朝向的问题，但也只能通过实验推出，鱼这么选跟水流速度无关，至于真正的原因，目前还不知道。
综上，选 C 。
