difficult to find them.in parts of africa, though, people and animals looking for honey have a strange and unexpected helpera little bird called a honey guide.the honey guide does not actually like honey，but it does like the wax(蜂蜡)in the beehives (蜂房). the little bird cannot reach this wax, which is deep inside the bees nest.so, when it finds a suitable nest, it looks for someone to help it.the honey guide gives a loud cry that attracts the attention of both passing animals and people.once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest.when they finally arrive at the nest, the_follower reaches in to get at the delicious honey as the bird patiently waits and watches.some of the honey，and the

trees，and it is difficult to find them.以及第二段的第二句the little bird cannot reach this wax，which is deep inside the bees nest.可知，由于蜂房高居树上并且隐藏在树丛中，所以它们不容易被发现，因此b项正确。2c词义猜测题。对于画线部分的前一个句子once it has their attention，it flies through the forest，waiting from time to time for the curious animal or person as it leads them to the nest.该句中them指the curious animal or person，所以，下句中的the follower也指的是the curious animal or person，即“寻找蜂蜜者”，所以c项正确。3a推理判断题。根据文章的描述，蜂蜜向导鸟寻找蜂蜜是通过吸引人或动物来帮助它们得到自己需要的蜂蜡，对于动物来讲，它们懂得利用外力来达到自己的目的，这种方式是很特别的。蜂蜜向导鸟通过这种方式找到自己的食物，所以a项是正确的。4d标题概括题。本文主要介绍了蜂蜜向导鸟用自己的独特方式找到食物的过程，并且帮助人类和动物获得蜂蜜，所以对于人类和动物来讲，它是有益的帮助者，所以d项(蜂蜜爱好者的帮助者)意义正确。a项意为“野生蜜蜂”；b项意为“蜂蜡和蜂蜜”；c项意为“非洲养蜂”，三者均不能表达出文章的主旨。冲击“211”(长难句分析)once it has their attention, it flies through the forest, waiting from time to time for the curious animal or person as it leads them to the nest.分析句子的主干是：.it flies through the forest，.状语从句：once_it_has_their_attention，.状语从句：.as it leads them to the nest, waiting from time to time分词短语作状语。译文一旦引起了他们的注意，它就会飞越森林，并且在引领他们朝蜂巢前行的途中，它还会不时地停下来等一等这些好奇的动物或者人。they will quickly arrive whenever a beekeeper is taking honey from his beehives, and will even enter churches when beeswax candles are being lit.分析这是一个并列主从复合句，主句是they_will_arrive_and_will_enter_ churches。状语从句.whenever_a_beekeeper_is_taking_honey；状语从句.when_beeswax_candles_are_being_lit译文每当养蜂人从蜂箱采蜜的时候，它们(小鸟)都会立刻到来，而且每当蜂蜡在点着的时候，它们都甚至飞进教堂。iii.根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。brain transplantsresearch on the human brain has been attracting more and more scientists in recent years._1_if we compare a human brain to a hard disc, what the scientists are doing is to make better use of the hard disc.the idea that a human brain could be transplanted(移植)may come from frankenstein.in 1999, an experiment turned a bear into a dolphin(海豚)_2_they were made of the memory area in the dolphins brain containing information about swimming.they had a series of useful information, which was saved into a buttonsized chip(芯片)later the information was transplanted into the action memory area in the bears brain._3_it proved to be a highly successful experiment and a bear was turned into a dolphin.recently, another memory transplant was performed at the motor nerve rescarch instance of the university of california.the experiment had an entire transplant of the memory area._4_the transplant was performed from a dog named cenius to a dog named idiot.cenius could follow up to 100 gestures and orders made by its master.it was a real genius in memorizing.however, idiot had no contact with people since its birth.it became an animal with nothing in its brain, without any memory._5_when the two dogs woke up, idiot had grasped all the abilities cenius possessed；it was good at memorizing and sensible.it could follow every gesture and any command given by its master.but cenius gave no response to its master, and did not recognize him at all.athe experiment was a complete success.bit included actions, moods, logic, words, images, etc.cthen it was released(释放)by means of electric power.ddifferent images have different meanings in the memory area.eusing the most advanced technology, detailed images were produced.fdiscoveries show that messages are carried by the central nervous system in the brain.gone of the latest topics is how to change the human brain or combine it with the computer.【语篇解读】 脑移植是人类在追求科技进步的路上一座难以攀登的高峰，但是人类已经在这个领域取得了巨大进步。1g上一句的attracting more and more scientists in recent years和该项的how to change the human brain or combine it with the computer吻合，说明人类对脑移植的兴趣从来就没有停止过。2f上一句的turned a bear into a dolphin和本项的carried by the central nervous system in the brain吻合，说明物种的转变是通过脑移植完成的。3c上一句的transplanted into the action memory area in the bears brain和该项的then it was released(释放)by means of electric power是连环环节或者步
