In the summer vacation, I paid a visit a mountain village in a suburb of Xi’an. No sooner had I got off the bus when I was greatly surprising to see all the changes. It was far better than I had been expected. Now every family can drink cleanly running water. The villagers needn’t carry water himself any more. Firewood is no longer used for cooking. Marsh gas, a new cheap clean energy, make it very convenient to cook and light. As all the families have color TV set, they can enjoy plays at home. It impressed me most was that the best building in a village was the school. I hope the mountain village will become better and better.

1.pay a visit to=visit，参观某地、拜访某人。
2.固定短语的考查，no sooner......than,一......就......。
3.某人惊讶用be surprised,令人惊讶用surprising。
4.被动语态误用。我原先所期待的，用过去完成时，但无被动。
5.修饰名词water,用形容词clean。
6.代词的考查。主语是the villagers,对应的代词应该是themselves.
7.主谓一致的考查。主语是Marsh gas ,谓语动词用动词的第三称单数。
8.名词单复数的考查。所有的家庭不可能只有一台电视，故为复数。
9.主语从句的考查，难点。What引导的主语从句。也可以这么说 It impressed me most that the best building in a village was the school.此时，It为形式主语，that引导的从句为真正主语。
10.不定冠词的考查。特制用the.
