第一句的题是错的,应该是:She has won 。。。
1. A。She has won a lot of championships, hasn't she?
2. He started learning English 【at】 the 【age】 of five. 或者: by the age of five
3. 【Did】 she 【win】 another gold medal?
1。C翻译疑问句,前肯后否,动词保持一致
2. he started learning English (at )the (age)of five.
3. ( Did) she (win )another gold medal
