One day, I was cooking in the kitchen while the telephone rang. I went to answer it immediately. She was my close friend, Lisa. When we were talking on phone, the fire alarm sounds. I ran back to the kitchen only to find the room full of smoke and the beef bad burnt. I quickly turned off the gas, opening all the windows, and then went out of the house. In my surprise, the two fire engines were outside my house. I was quite worrying. I told the firemen that it was my careless cooking which caused the heavy smoke.

【解析】作者讲述了自己一次因为打电话而造成厨房着火的经历及采取的紧急措施。
1.rings改为rang.考查动词时态。与语境was cooking呼应可知，事情发生在过去，用一般过去时。故rings改为rang.
2.She改为It.考查代词。在电话中，一般用it指代说话的人。故She改为It.
3.phone前加the.考查冠词。固定词组on the phone意为“打电话，在电话里"符合语境。故phone前加the.
4.bad改为badly.考查副词。此处修饰过去分词burnt，在句子中作状语用副词badly。故bad改为badly.
5.opening改为opened.考查动词时态。此处open和turned off, went out of是并列谓语动词，用一般过去时。故opening改为opened.
6.but改为and.考查连词。此处关掉煤气，打开窗户和跑出房间三者表示逻辑上的并列关系，而非转折关系，用连词and。故but改为and.
7.In改为To.考查介词。to one’s surprise意为"让某人惊讶的是"符合语境，故In改为To.
8.engine改为engines.考查名词的数。与two呼应，此处用名词的复数形式。故engine改为engines.
9.worry改为worried.考查形容词。根据was可知此处用形容词作表语且修饰人，用worried。故worry改为worried.
10.去掉it.考查强调句型。it is...that...是强调句型，本句是对“my careless cooking”进行强调，it是多余的。故去掉it.
