She goes to school by bike . 注：在这种结构中，一定要注意第三人称单数形式。 一般过去是表示过去某时发生的动作或存在的状态, 常和yesterday (昨天), last night(昨晚), in 1980, a week ago(一周前), on Saturday morning, just now等表示过去的时间词和词组连用.

No, I wasn’t. Yes, they were. No, they weren’t. Eg:1. Mike was in the United States last year. Mike was not(wasn’t) in the United States last year? Was Mike in the United states? Yes, he was. No, he wasn’t. 2. They were at home yesterday. 注意:带有be动词的过去时的句子,一定要看清主语后面在正确选择用was还是were. B.谓语是行为动词如(go, watch)等过去式. 除了be动词外的其他动词的过去时的基本句型如下: 肯定句:主语+动词的过去式+… 否定句:主语+didn’t+动词原形+… 疑问句:Did+主语+动词原形+…? 简约回答:Yes,主语+did.
