+ v& ] A* ?7 x' R i; u2 O8 K4 l长文：新旧观点/ q; t Z! G, x# Q4 Y! G# Q
第一段：讲了海里动物分布特点，特别提到了在hyfrothermal vents areas动物的与众不同
4 L+ Y, K% F% m; y5 z第二段：旧观点关于hyfrothermal vents areas动物的食物来源: Y% z5 h0 |" f: S1 F3 t
第三段：指出旧观点的错误

7 T: P# x( S% z) q( E! ~
16．细节题(我没有什么好办法，一个一个来)4 i- x, N) S1 E; S6 O
A warm-water vents 怎样形成，没讲，文章主要是关注warm-water vents附近动物的食物来源，并没有讲warm-water vents怎样形成, E/ N8 P7 ]# N: O d, v% b
B 问warm-water vents附近动物的食物消耗量和deep-sea faunas 相比，定位第二段1 S2 Q' O' P) H% M6 u
L10 the food supplies necessary to sustain the large vent communities,however, must be many times the ordinary fallout.这不说明它与deep-sea faunas相比的情况，而且，文中没有提到similar size的问题(注意，关于对比一定要记录)
7 I. h( [2 ^- W/ ]4 nC 用bacteria 来定位 L39 No bacteria can survive such heat,and no bacteria were found there. There指的就是上文的smokers. 所以C对
' X% j- f* z' A+ H( D" ?D 用hydrogen sulfide 定位 L18 hydrogen sulfide was found in vent water, many vent-site bacteria were found to be capable of chemosynthesis.讲的是vent-site bacteria与chemosynthesis有关
( `" W9 d/ E5 rE 文中没有解释smoke location的地方（这个我自己觉得很麻烦，找不到好办法，就感觉它不是）! ^6 F7 x* h7 u. i
! W- d* {- U& J9 ^1 H17.细节0 |. D6 m! U5 T+ L6 P
定位deep-sea fauna,L1 deep sea typically has a sparse fauna dominated by tiny worms ….However, near hydrothermal vents areas of the ocean where warm water emerges from …. Densifies of huge clams..,说明生活在deep-sea的动物比生活在hydrothermal vents的动物要小。
9 c2 {$ u& { d6 n, E! E, B
# ^5 K* B8 _, x3 S- A18．主题, f# s5 o4 l! p: e
新旧观点对比，指出旧观点的错误，用证据证明新观点
" B# R, p5 G( [: W, j+ E0 D4 Q，选D" l2 Z* d7 q7 J
19.缺陷题，问的是旧观点缺陷，在第三段找，用bacterial chemosynthesis定位 Lthis suggests that bacterial chemosynthesis is not a sufficient source of nutrition. 原因是前一句。Some of the large sedentary organisms associated with vents are also found at ordinary deep-sea temperatures many meters from the nearest hydrothermal sources.选A
* \! V1 N+ n, x# d2 U1 J( ]& [+ f- N% } [, G L( _, y
20.细节 定位L10 however(注意转折), must be many times the ordinary fallout.原因是前一句，The food supplies necessary to sustain the large vent communities,III对，选B/ e. M- E$ u4 f3 x: [- l3 [" W9 B
21.用smoker定位，L38 往下看，在 L41 Unless(注意) smokers are consistently located near more hospitable warm-water vents, chemosynthesis can account for only a fraction of the vent faunas.说明chemosynthesis不足以提供足够的食物来源(only a fraction of …)% u# p0 C) z7 B$ e( l
22.细节，定位第二段首句， Most deep-sea faunas rely for food on particulate matter, ultimately derived from.photosynthesis, failing from above
/ i0 Z* U2 B1 h8 y' c选B (provide an important source of nutrition for vent faunas)，这个从Most deep-sea faunas rely for food on…可以得到, W$ l* P- i8 Y0 u, R) w: b

这篇长文很奇怪，居然没考新观点0 ^/ T, i4 D1 {& K. h8 `$ ~

23．去非题，考虑什么时候有这种禁忌L 12 In prehistoric times, when food was so precious and the on-looks so hungry,取非，在有充足的食物的社会不会出现这种现象选A% n% g" ]5 u: b; b9 O, w
24.定位同23 L12,强调食物有限的情况下，有这种禁忌（一个地方的正反两种考法）,选C
3 S0 R, }! a) q) ^' k25.作者观点 L9 Undoubtedly such elements exist in the taboos, but there is an additional element with a much more fundamental importance.说明是incomplete的，选D
/ ?6 @. g) M: w26.同25，作者认为早期的解释是又局限的，选A

这个题考点也太集中了， |
