One evening I was going back from a supermarket. As I approached my car, I noticed one person     1     seemed a bum (流浪汉) standing beside me. I expected that he would ask me     2     some money, so I asked him if he needed help and his response was “Don’t we all?” I have never heard words     3     (astonishing) than those. Although I had money and a place     4     (sleep) in, I recognized that I needed help too. It was a true discovery to me.

The protection of the Yellow River is one of the top concerns for Chinese leadership. In the past two decades, the Chinese government     1     (strengthen) the protection of wetlands along the Yellow River,     2     (make) various wild birds gather in this area. The rising number of wild birds has brought a benefit for birdwatchers, who are very thankful for     3     the government has done for the people. Further efforts will be made to bring more beautiful environment to the Yellow River.
