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

16.细节题(我没有什么好办法,一个一个来)3 }4 L @7 ?/ n$ w8 b. U' J, T3 B& S
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
0 d5 [$ M! W: t! U, F! ]3 sB 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* v$ ^6 C7 {2 m9 B& ]7 c0 E
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)" H- l, d! @& j! ]* x9 `1 o% y* l
C 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
$ F- B4 A5 w* R" _ uD 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0 Y x' s1 x/ d5 [5 i# X. b

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
1 N7 u. S- H" u( }! o' z: e# C7 p1 f( G6 A$ Q; z
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
& I# Z: B7 ~, f3 D3 U1 f21.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 …)5 H" N* a2 d n/ `' n

短文:讲的是关于进食的一些禁忌以及原因
