“It is + 被強(qiáng)調(diào)部分 + thatwho + 句子其他部分”是使用最廣的強(qiáng)調(diào)句型。除了謂語(yǔ)動(dòng)詞不能強(qiáng)調(diào)外，句子中其它成分，如主語(yǔ)、狀語(yǔ)、賓語(yǔ)或賓語(yǔ)補(bǔ)足語(yǔ)都可以用該句型中加以強(qiáng)調(diào)。
A. 用強(qiáng)調(diào)結(jié)構(gòu)強(qiáng)調(diào)句子成分
1．強(qiáng)調(diào)主語(yǔ)
被強(qiáng)調(diào)的主語(yǔ)是人時(shí)，可用It iswas ... thatwho ...，但如果被強(qiáng)調(diào)的部分既包括人又包括物，只能用that。
