gre和專八哪個難
GRE考試在英語考試的難度中可以說是還是比較大的，而在國內，英語專業八級考試可以說是非常難的了，有人就會將GRE和專八作比較，究竟哪一種考試難度更大呢?爲解決這個疑問，收集整理了一些資料，供大家參考。
gre和專八哪個難
在衆多的出國留學的考試中，大家不免就會將這些考試來做比較。比較這些考試所需的詞彙量、比較整體考試所需的準備時間等等。都是英語考試，國內的一些考試也是被大家拿出來進行比較。
比如這個問題。GRE和專八哪個難度比較大呢?回答這個問題，需要不少的知識做鋪墊，在這裏智課妞就爲解決這個問題進行相關資料的收集整理，幫助大家對這兩種考試有更深入的瞭解。
GRE和專八難度對比：
都說GRE考試難度高，那麼其難度究竟有多高呢?
英語專業八級堪稱國內專業英語證書中難度最高的一種，它與GRE相比難度又如何?
下面小編就爲大家稍作介紹。
考試形式有本質區別
首先新GRE考試是一門英語考試，但是隻是形式上的英語考試，本質上它和其它所有的英語考試有着天壤之別。大家不要忘了新GRE考試是美國研究生入學考試，是爲了檢驗一個本科生有沒有能力進入研究生院進行深造。
因此新GRE考試是一種能力的考試，是對一種思考、創新等科研所必須的綜合能力的檢驗，只不過它是美國這樣一個英語國家的考試，所以就是所謂的形式上的英語考試。
GRE考試詞彙量秒殺專業八級
新GRE考試詞彙量要求就要高於英語專八，即使考過英語專八的同學，也要在詞彙量方面，進行鞏固與加強，才能將新GRE考試拿下。對比新GRE考試難度和專八難度則不好比較，有重點的複習是關鍵。
看完上文內容，想必大家對於兩項考試的難度也有了一定的瞭解。其實，單純意義上的難度比拼並沒有太大意義，能夠考過其中一門考試的人，也不一定就能順利通過另一門考試，只有踏踏實實地備考複習，纔是考生應對GRE考試最好的方法。
TIPS：英語專業八級考試知識科普
英語專業八級考試(TEM-8，Test for English Majors-Band 8)，全稱爲全國高校英語專業八級考試。自1991年起由中國大陸教育部實行，考察全國綜合性大學英語專業學生。英語專業八級考試是由高等學校外語專業教學指導委員會主辦的(非教育部主辦)。它在每年的三月份舉辦一次，考試在上午進行，題型包括聽力、閱讀、改錯、翻譯和寫作。 考試內容涵蓋英語聽、讀、寫、譯各方面，2005年又加入人文常識。筆試形式考覈。口試另外考覈，名稱爲“英語專業八級口語與口譯考試”。
GRE閱讀題目解析:守窩長尾石龍子
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.

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.
我們的研究顯示，守窩長尾石龍子(一種蜥蜴)被移動的距離越短，返家(回窩)成功率越高。
2
There are two reasons why homing success rates decreased with increasing displacement distance.
隨移動距離變長回窩成功率變低的原因有二。
3
One possibility is that females were simply displaced too far to find their way home.
一種可能，單純是因爲雌石龍子被移動得太遠，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，這不大可能，因爲一些個體無論被移動多遠，都成功回窩。
5
The second possibility deals with trade-offs between the risks associated with making a long return trip and the benefits of returning.
第二種可能，涉及 在 長途跋涉回家的風險 與 回到的好處 之間權衡利弊。
6
Animals should expend energy only when the associated costs are low.
動物理應在相關代價較低時消耗能量。
7
As reptiles increase the time spent moving, their daily energy expenditure increases dramatically.
因爲爬行動物移動慢，它們一整天消耗的能量劇增。
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.
隨着被移動的距離增加，回窩要消耗的能量，以及在此期間蛋被吃掉的機率都增加了。
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.
比如說，雌石龍子花 130 小時(5.5 天)跋涉 300 米回窩，已經足夠蛇定位以及吃掉所有的蛋。
(clutch 一次產或孵的蛋)
10
However, females with larger clutches were more likely to home at distances over 50 meters.
然而，守着大窩的雌性仍然更可能在被移動超過 50 米的情況下回窩。
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.
對於這些雌性來說，讓更多蛋成功孵化的相對適應性利益，超過了回窩會消耗的能量，即便蛋可能已經被吃了。
(fitness 最早講這個概念在 15 / 36 P1，有興趣的同學去翻
基因適應度，指特定條件下，某個體讓自己的基因進入後代基因庫的能力，也就是讓自己攜帶的基因儘量延續下去的能力。

評估 對 一項關於長尾石龍子的觀察發現 的多種解釋。
finding 就是有的回窩，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.
選 D
難題。
首先在於問法，即對於那些被移動多遠都回窩了的石龍子，這句話隱含了什麼假設。
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 連起來看。
句 3 說，一些雌石龍子不回家，單純是因爲找不到路了，to far to find their way home 。句 4 則否認了這種可能 this is unlikely，因爲有一些始終要回家，也成功地回了家。
看到這裏，如果你足夠敏銳，就該意識到這樣一種情況：可能有一隻，它想回家，但因爲找不到路，只能在外面瞎打轉幹着急。
文中有提到這樣的，想回家又回不了的石龍子嗎?
沒有。
後文提到了兩種情況，一種是想了想不回了因爲不值(言外之意，想回還是能回的)，一種是想過了無論如何要回也確實回去了。
你注意到了嗎，兩種情況的區別只在於 trade-offs 對收益與風險的權衡，不在於認路的能力，即文章的作者認爲所有石龍子都一樣認路，想回家就一定能找到路。
這就是這句話隱含的假設：回家的並不比其他更認路。
現在做完這道題，你認爲作者在文中的論證是否存在問題?其結論是否成立?
其實，這道題非常犀利地指出了文章邏輯的不足。作爲一項意在考察蜥蜴是否回家的研究，竟然因爲有的蜥蜴成功回家，就假設所有蜥蜴都像上帝一樣認路。回頭再看看，這道題中竟然一個科學家的名字都沒出現過，我懷疑這篇 “ 文章 ” 是 ETS 編的，而不是改寫的，故意賣個邏輯上的破綻好出題。
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.
選 A
注意問法，從 “ second possibility ” 出發推斷可能的解釋。根據句 10 - 11 可選出 A 。其實 B / C / E 都是比較有可能的推測，只是因爲文章的邏輯缺陷，三者都得不到表達。
GRE閱讀題目解析:河生雌䲁魚選擇巢穴
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.
選擇巢穴時，河生雌䲁魚(一種小魚)似乎對大小和朝向都有挑剔。
(
䲁 [blenny]
鱸形目䲁亞目許多種魚類的統稱。大多體型小，海產，廣佈於熱帶到寒帶海域。體細長如鰻。生活於各種生境，包括巖潭、沙灘、礁盤和藻牀。多數生活於淺水，但有些可深至水下450米處。有些主要爲草食性，有些則部分或完全爲肉食性。一般爲底棲，沒有多少經濟價值。

2
Blennies deposit their eggs preferably in nests under large stones and in nests facing southeast.
䲁魚更喜歡把卵產在大石下以及朝向東南的巢中。
3
Southeast-facing nests contain larger egg clutches, a fact that cannot be completely explained by differences in nest stone sizes.
產在朝向東南的巢中的卵更大，這無法用巢的大小完全地解釋。
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，最近一項研究顯示東南朝向與其他朝向，巢受水流沖刷的速度與巢口的水流速度都相近。
(這裏翻譯不是很確定，坦白一下我的想法。
upstream 逆流的，向上遊的
upstream of the nest 我理解爲，巢是不動的，upstream of the nest 指水流沖刷巢，也就是那塊石頭的速度
有不同理解請留言指導我)
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，似乎是雌魚擇巢的特徵，而不是因爲巢口水流速度而選擇巢口的朝向。
6
The reasons for this preference are unclear, however.
然而，這種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
選 B
確定巢的朝向是河生雌性䲁魚產卵的決定因素。
establish 此處解釋爲 確定、證實。
A 錯。句 5 告訴我們，水流速度沒啥區別 similar 。
C 錯。文章沒有質疑大石偏好，只在句 2 提了一下：Blennies deposit their eggs preferably in nests under large stones and in nests facing southeast.
D 錯在 features of female river blennies，沒有討論魚，只討論了巢，水流什麼的。
E 錯。沒有比較兩種因素哪個更重要。
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
選 C
去掉一種可能的解釋。
需要讀懂整段才能做對：
魚產卵有兩種偏好，大石頭，開口朝東南。文段着重討論了開口朝向的問題，但也只能通過實驗推出，魚這麼選跟水流速度無關，至於真正的原因，目前還不知道。
綜上，選 C 。
