5、ers.So，recitation of the texts will help improve your language ability.【答案与解析】1until/tilluntil“直到才”，让学生们读课文直到会背。2However/Nevertheless和上文构成转折关系。作者让学生反复读课文直到能背诵，而有些学生非常厌烦这样做。3tiredbe tired of是固定搭配，含义为“对感到厌烦”。句意见上题解析。4useless一些学生对这种做法表示厌烦，他们认为这种做法既困难又无用。此处所填形容词应与hard一致，故不用useful。5longin the long run “从
6、长远来看，终究”。虽然背课文很花时间，但从长远来看这样做是很有好处的。6responsegive response to对做出反应。此处缺少一个名词，故用response。能对各种语言情形做出反应。7Besides含义为“而且，还有”，表示递进关系。上段讲了学生的看法之一即“背诵无用”，这里讲了另外一种情形，“背会了的东西很容易被遗忘”。所以此处用表递进关系的副词besides。8but和上文构成转折关系。会背的东西的确很容易被忘记，但你不必担心。9raised根据上文的level进行判断，当你在诵读并遗忘这些课文的过程中，你的语言水平正在被提高。10that或which关系代词连接定语从句，

D推理判断题。由第三段第二句“he didnt thinkbut that he hoped”可推知。3A 细节理解题。由倒数第二段首句“Hundreds of Haifa residents gathered around Haifa Bay to see”可知当地的居民们很好奇，都跑去观看。4C主旨大意题。本文第一段为事件的总述，由此段可知本文主要说一群海豚出乎意料地游到了被污染的水域，然后又游了出来。BOne type of fish is name
16、d the salmon(大马哈鱼)There are many different kinds of salmon，but almost all of them mate(交配) in a very strange way.They are born in small，fresh water rivers.They live in the river for a year，and then swim downstream to a bigger river and eventually to the ocean.In the salt water，they eat constantly an

22、r stop swimming.CBecause they are afraid of bears.DBecause the different water makes them hungry.()8.Salmon return to fresh water in order to _.AmateBprovide nutrition to other animalsCmate and provide nutrition to other animalsDmake a difficult journey【答案与解析】5B词义猜测题。as if by magic意为“似乎被一种神奇的力量指引”，即作者对大马哈鱼能准确无误地游回自己的出生地感到不可思议。6D细节理解题。根据第三段前半部分可知，前三项都是大马哈鱼历经艰辛重新回到淡水后的变化，第四项在本段中没有信息支持。7A推理判断题。第三段第二句提到大马哈鱼进入淡水后就停止进食，本段后半部分则是它们在回家途中需要逆流而上，而且还要跳过瀑布，由此可推测它们在海洋中大量吃东西的原因是为以后返回出生地积聚能量。8C细节理解题。根据最后一段可知幸存下来的大马哈鱼在同一条河中交配，它们死后的尸体又为河中以及周围的动物提供营养，所以选择C项。前两项只是原因之一；最后一项是它们的后代的行为。
