答案：D;A;B;C;A;C;D;A
解析：

解析：这篇文章讲述了狗作为人类的朋友，在许多方面给予人类的帮助。文章在时态和语态等方面变化多端，错综复杂，多处涉及到被动语态，以及各种时态之间的区别，答题时应特别小心，注意区分。1．既然是故事，那一定是过去发生的事情，故用过去时helped． 2．句中lost in snow作定语修饰people. 4．用was表示过去发生的事情。 6．词组quite a few表示“不少，许多”，易误选为A． 8．该题强调一种状态，即“还没长大”。易误选成现在完成时。 　　拓展延伸：提高完形填空答题能力的最好方法是精读。对所遇到的文章进行反复研读，揣摩文中语法、词汇等各种语言素材在运用中的变化，使自己对语言变得更加敏锐。
