答
I sometimes practice conversations with friends.I think it （helps)有时候我和朋友们练习对话,我觉得有帮助,第三人称单数,动词加sWe don't know _______ they broke the glasses for. A.why B.what C.when D.whe...请问有这个固定句型：think it +形容词 吗可以说I think (that) it is +形容词，这里的that可以省略也就是说think it +形容词是不存在的？可参考答案给的是helpful并不是说不存在，只是不常用。你可以说I THINK IT HELPFUL TO DO SO，这里的IT做形式宾语，TO DO SO 做真正的宾语也可以说I THINK IT IS HELPFUL TO DO SO，这里IT作宾语从句的形式主语，to do 不定式做真正主语如果让老外来选，第一答案肯定是helps.
