完形填空。 Science seems to be getting closer to answering a very old mystery. Homing pigeons can be 1 hundredsof miles from their homes. When they are let to go to 2 again, they find their way home. Because of this
special ability to 3 , pigeons have been used 4 messengers for hundreds of years.
Today people even breed homing pigeons for 5 at a sport. The birds are shipped to some chosen 6 a
few hundred miles away. Then all of them are let to go together. The winner is the bird that gets home 7 . A
good race can make it home from 500 miles away 8 a single day.
The mystery of the homing pigeons is how they 9 directions and how they find home. The first part seems
to be pretty well 10 , and we know of two ways that pigeons tell directions. First, they use the sun.
Experiments show that homing pigeons can tell 11 by the sun. What happens when the 12 is darkly
overcoat by clouds and no one can 13 where the sun is? Then the pigeons still find their way home.
Naturally, people have wondered whether pigeons might have a built-in compass 14 that would tell them
about the direction of the 15 magnetic(磁的)field. Many different kinds of experiments were 16 . Here's
what the scientists decided 17 they had made experiments many times. When pigeons can see the sun, they
use it as their 18 means of direction-finding. When they can't see the sun, they use some 19 way to sense
direction from the earth's magnetic field.
But how do pigeons know 20 direction is toward home? What do they use that we would call a map? These are other questions to be answered. ( )1. A. carried

考点
据考高分专家说，试题“完形填空。 Science s.....”主要考查你对 [日常生活类阅读 ]考点的理解。日常生活类阅读
日常生活类阅读的概念：
日常生活这一话题主要涉及人们衣食住行等方面的活动。这一话题的选材主要针对人们日常的工作，生活以及学习情况。做这一类题时，最主要的是要把握好人物的活动内容，时间和地点。
日常生活类阅读题答题技巧：
【题型说明】
该类文章内容涉及到人们的言谈举止、生活习惯、饮食起居、服饰仪表、恋爱婚姻、消遣娱乐、节日起源、家庭生活等。文章篇幅短小，追根溯源，探索各项风俗的历史渊源，内容有趣。命题也以送分题为主，如事实细节题、语义转换题、词义猜测题和简单推理判断题等。虽然这类文章读起来感觉轻松，试题做起来比较顺手，但绝不能掉以轻心。因为稍不留神，就会丢分。
【备考提醒】
为了保证较高准确率，建议同学们做好以下几点：
1、保持正常的考试心态。笔者在教学中发现，越是容易的试题，同学们越是容易失分。为什么呢？因为在这种情况下，同学们极易产生麻痹思想，认为题目好做，就不引起高度重视，于是思维不发散、不周密。而命题人就是利用同学们的这一弱点，设计陷阱题。所以，无论试题难易与否，我们都要保持正常的考试心态。试题容易，不欣喜；试题难，不悲观。
2、根据前面讲到的方法，认认真真、细细心心做好事实细节题。
3、做好语义转换题。这类题是根据英语中一词多义和某些词语在文中能表达一定的修辞意义的原则而设计的。要求同学们解释某生词的含义，确定多义词或短语在文中的意思，确认文中的某个代词所指代的对象，或者对英语中特有的表达、格言、谚语进行解释。这种题要求同学们一定要根据上下文猜测词义或理解句子，切不可望文生义。
4、做好简单推理判断题。简单推理判断题要以表面文字为前提，以具体事实为依据进行推理，做出判断。这种推理方式比较直接，只要弄清事实，即可结合常识推断出合理的结论。
