问题描述：
How great your idea ____ (sound)!I love it.是不是填sounds?
Susan,___(not be) careless when crossing the road.是不是填isn't?
Not only the twins but also their friend __ (plan)a trip to Shanghai at this moment.是不是填are planning?
答
第一个是sounds,随便他怎么感叹，主语是idea,谓语是三单
第二个句子，要确定是，susan 后面有逗号的情况下，用don't be
第三个句子，要用就近原则，因此看friend, 填，is planning
答
1 对,是：sounds
2 don't be ( 祈使句否定句是助动词don't +动词原形）
3 is planning ( their friend 是单数,not only ...but also ...是就近原则）
