　　解题思路：

　　1. abandon是及物动词，在此需要用它的被动语态形式。

　　2. account for是固定搭配。本句为非限制性的定语从句，which表示主句的具体内容。

　　3. 训练adequate的拼写。

　　4. 训练adventures的拼写。本句为非限制性的定语从句，which引导的非限制性定语从句修饰主句的a movie。本句应当作为重要句式记忆。

　　5. adopt在这个语境中要用一般过去时。当然，adopt另有“领养”的意义。

　　6. 在该语境中alternative被用作名词，have no alternative but to do sth.意为“除……外别无选择”，表示相同意义的词组还有：have no choice but to do sth.

　　7. 在该语境中amateur是名词，请注意它的拼写。本句是Considering … ，… “考虑到……, ……”是分词的固定用词，应当作为重要句式记忆。

　　8. 在该语境中anniversary是名词，请注意它的拼写。golden wedding意为“金婚纪念”。

　　9. appeal是不及物动词，appeal to sb.意为“对某人有吸引力”。如果能掌握appealing的形容词，意为“吸引人的”的用法就更好了。如，本句也可以改成His idea of traveling overseas sounded appealing to us all.

　　10. 动词argue的名词形式是argument，要注意它的拼写。“反对……的争论”或“支持……的争论”应该是argument against sth. 或argument for sth.，介词“against”和“for”表示“反对”和“支持”。
