解析

【解析】
1. while引导时间状语从句时,常接延续性动作的过去进行时,主句用一般过去时。将延续性动作"We were having a meeting"置于while从句中,主句为"The teacher came in",合并为While we were having a meeting, the teacher came in.

3. 过去进行时的否定形式是在be动词后加not,were的否定缩写为weren't,故改为They weren't having dinner when the typhoon hit the city.
4. 过去进行时的一般疑问句需将be动词提前至句首,即Was the boy sleeping when his mother left the bedroom? 否定回答结构为"No, 主语+be动词否定形式",即No, he wasn't.
5. 对过去正在进行的动作提问,用"What were you doing..."结构,故问句为What were you doing when the strong wind started?

四、根据材料内容选择最佳答案。
On 12th May, 2008, a day that started like any other, a very strong earthquake suddenly struck Wenchuan, a quiet county in the mountains of Sichuan Province, China. It is remembered as one of the most powerful earthquakes in China's recent history.
The damage (破坏) was very serious. In less than a minute, the lives of millions of people changed completely. A large number of houses, schools, and roads were broken into pieces. In towns that were hit the hardest, like Beichuan and Yingxiu, almost all the buildings fell down. It was a very sad day for the whole country. Over 69,000 people lost their lives, and many were injured and lost their homes. The earthquake was so strong that it even caused mountains to fall and created new lakes, which were very unsafe.
However, in the face of this disaster, people showed their courage and kindness. Many soldiers, doctors, nurses, and volunteers came from all over China to the disaster areas. The soldiers moved heavy stones away to look for people in the fallen buildings day and night. They tried their best to save as many lives as possible. The medical workers set up temporary hospitals in the fields to care for the injured. Many kind people brought food, water, clothes and tents to the people who lost their homes.
The road to recovery (恢复) was long. But with the help of the people across the nation, the rebuilding of Wenchuan began. New and safer houses, modern schools, and hospitals were built over the following years.
Though people's life in Wenchuan has returned to normal, the memory of that difficult time remains. The people in Wenchuan will never forget the great courage they found in themselves. Most importantly, they will still remember how the love and help from others got them through that difficult time.
