did any one of you see the accident-----yesterday.a.happen b.happened c.was happened d.happens

选b Did any one of you see the accident-----yesterday?本句是一个一般疑问句,借助动词did提问,saw还原成 see .see 后 是一个宾语从句 根据yesterday 可知是过去式 排除 A,C,D答案谢谢i would like to write to a boy,i want to -------his hobbies. a.know b.know aboutb know意思是了解 熟悉，know abut 是了解某事，了解……的情况根据句意应该是我想写封信给一个男孩，我想要了解他的爱好。
