学员疑问:老师,Our research results, published this month as a cover article in the Journal of Materials Chemistry B,(IF=7.0). 这句话哪里有错误吗?
老师解答:句子缺谓语动词,可以改为Our research results were published this month as a cover article in the Journal of Materials Chemistry B, which has an impact factor of 7.0.
点评分析:检查句子是否有误可以从结构和用词上着手。结构上,句子必须要有完整,主系表或者主谓宾结构,再检查名词单复数,谓语动词时态语态,以及主谓一致问题。此句中谓语published的语态有误,应该用被动语态。
