Question

閱讀理解 　　Most animals only have animals of a different kind for food．But sometimes two kinds of animals come together in a partnership(伙伴關系)which is good for them．You may have noticed some birds on the backs of sheep．This is not because they want a ride, but because they find easy food in the parasites(寄生蟲)on sheep．The sheep let the birds do so because they can stop the parasites from troubling them．So though they can do with it by themselves, they can do better together with each other． 　　Sometimes an animal has a plant partner．The relationship develops until the two partners cannot do without each other．This is so in corals of the sea．Inside their bodies they have very small plants, which act as “cleaners”, taking the useless things from the coral and giving oxygen in return．That is what the animal needs to live．If the plants are killed, or are even kept from receiving light so that they cannot live as usual, the corals will die． (1) Some birds like to sit on a sheep because ________． [　　] A． they can eat its parasites B． they enjoy traveling with the sheep C． they can’t live without its parasites D． they want to find the warm place (2) The underlined word “they” in the first paragraph means ________． [　　] A． birds and parasites B． birds and sheep C． parasites and sheep D． birds, parasites and sheep (3) We learn from the passage that corals need plants for ________． [　　] A． friends B． light C． food D． oxygen (4) The Chinese for the word “oxygen” is ________． [　　] A． 氧氣 B． 空氣 C． 廢氣 D． 二氧化碳 (5) What is the second paragraph mainly about? [　　] A． Some animals and plants cannot live without each other． B． Some animals and plants cannot develop their friendship easily． C． Some plants eat each other． D． Some animals live better together．

Answer 1

答案：1．A;2．B;3．D;4．D;5．A;
解析：

(1)	本題屬于表層理解題．答案即在“This is not because they want a ride, but because they find easy food in the parasites(寄生蟲)on sheep．”一句之中．
(2)	前文中的“The sheep let the birds do so because they can stop the parasites from troubling them．”的意思是說“綿羊讓鳥兒落在自己身上，因為鳥兒可以將它們身上的寄生蟲吃掉．”；另一句“So though they can do with it by themselves…”的意思是說“盡管它們自己也能對付寄生蟲……”．綜合上面兩句話的意思，再結合“…they can do better together with each other．”這一句話，即得答案．
(3)	顯然，根據(jù)“…taking the useless things from the coral and giving oxygen in return．That is what the animal needs to live．”這兩句話可知，珊瑚需要植物提供的氧氣才能生存下去．
(4)	聯(lián)系生物學常識，氧氣是各種生物賴以生存所必需的，所以由此可以推測出該詞的意思是“氧氣”．
(5)	根據(jù)這一自然段的內容，珊瑚和它們體內的植物具有相互依存的關系．因此，答案非A莫屬．選項D迷惑性較大．因為這一自然段主要說明了珊瑚與體內植物的關系，它們在一塊生存得很好．但選項D意思是“一些動物在一起生存得更好．”只要注意“動物”和“植物”這兩個字眼，即可將此項排除． 　　自然界中里的事情總是那么的奇妙．很多動物都以不同種類的動物作為自己的食物，有時兩種動物還具有伙伴關系呢．有些動物也以植物作為伙伴．比如：海洋生物珊瑚的體內有一種很小的植物．這些植物消耗珊瑚身體內無用的東西，并釋放出氧氣．而這些氧氣又是珊瑚生存所必需的．
