As part of their training, guide dogs practise getting to and
around some of the most common places their owners will need to
go.
But before this, guide dogs must receive training in many other
areas. This is because guiding a person safely is more important than
knowing where to go.
Suppose a tree branch is lying on the path in front of a
blind person and his guide dog. Since the person cannot see the
branch, it's up to the dog to let him know it is there.

something in the way. The person will then work with his dog to
find a way past the branch.
Many people think a guide dog tells its owner when they can

答案
46. B 47. D 48. F 49. A 50. C
解析
【分析】
解题时首先通读全文，明确本文核心是介绍导盲犬的训练逻辑，以及导盲犬和盲人的协作模式。我们可以逐空定位前后文的线索：
1. 先看46空，前文抛出了“导盲犬怎么能这么有帮助？”的问题，后文直接给出了导盲犬反复练习熟能生巧的答案，所以要选承接问题、引出答案的选项。
2. 47空前文提到导盲犬要练习去到主人日常需要去的各类常见地点，空处自然是对这些地点的补充说明。
3. 48空后文明确描述了“如果树枝很大”的应对方式，按照并列逻辑，空处必然对应树枝较小时的处理方法。
4. 49空前文提到大众的错误认知：导盲犬会告诉主人什么时候可以过马路，后文用Instead转折说明实际情况和这个认知完全不同，所以空处要起到否定前文错误观点的作用。
5. 最后剩下的选项对应最后一空，全文都在讲导盲犬和盲人互相配合完成出行，收尾句自然是总结二者的协作关系，同时排除剩下的无关干扰项即可。
【解析】
46. 前文提出疑问"But how can they be so helpful?"，后文直接给出导盲犬靠反复练习变得有用的解释，B选项“这个问题的答案很简单”完美承接设问、引出下文内容，符合语境。
47. 前文提到导盲犬训练时要熟悉主人日常会去的各类常见场所，D选项“这些场所可能包括家附近的商店”是对前文"common places"的举例说明，指代衔接通顺。
48. 后文描述了如果挡路的树枝很大时导盲犬的应对方式，F选项“如果树枝很小，导盲犬可能会引导主人绕开它”和后文形成并列的两种场景的对应描述，逻辑连贯。
49. 前文提到很多人误以为导盲犬会告知主人何时可以过马路，后文用Instead转折说明实际是主人自己判断路况，A选项“这不是真的”直接否定了前文的错误认知，起到承上启下的转折作用。
50. 前文所有内容都在说明导盲犬不会替盲人做所有判断，二者需要互相配合完成出行，C选项“盲人和他的导盲犬始终是一个协作团队”对全文内容做了合理总结。
【答案】
46. B 47. D 48. F 49. A 50. C
