当堂达标（见导学案“当堂达标”）
答案与解析：
Ⅰ. 1. A　how long提问多长时间；how far提问距离；how many“多少”，提问可数名词的数量；how“怎样”，提问方式。由答语“It takes 20 minutes by bus.”可知问句意为“它花费多长时间？”，故选A。
2. B　由答语“It’s about 2 miles. ”可知问句是提问距离，故用how far。
3. B　“What do you think of... ”意为“你认为……怎么样？”，是固定句式。
4. C　how many“多少”；how much“多少（钱）”；how old“多大”；how far“多远”。由答语“14. ”可知问句询问年龄。
5. D　分析题干可知，空格处缺少状语，排除A、B两项；“by+表示交通工具的名词”意为“乘……”，故选D。
Ⅱ. 1. drives
2. grandparents’　根据句中them可知是去（外）祖父母的家，grandparents的所有格是在词尾加“‘”。
3. to go　take the...to do sth. 乘……去做某事。
4. doesn’t live　Bob作主语，谓语动词应用第三人称单数形式，否定式要借助doesn’t。
5. riding　of为介词，其后的动词应用-ing形式。
Ⅲ. 1. walks to　get to school on foot相当于walk to school， 意为“步行去学校”。
2. by train　take the train to...相当于go to...by train，意为“乘火车去……”。
3. drives to　go to...by car相当于drive to...，意为“开车去……”。
4. How far　对距离提问用how far。
5. How long does，take　对一段时间提问用how long，句中谓语动词是takes，故用助动词does构成疑问句，takes改为原形take。
　　Step 7　Homework
　　1. Talk about how you get to your grandparents’ home.
　　2. Prepare the words in Section B（2a-Self Check）before class.
