用
在“I’m sorry that．—／We were surprised that一．／They were disappointed that．．．”等引導(dǎo)的表示原因的狀語(yǔ)從句中,用“should十動(dòng)詞原形”.例如：
I’m sorry that he should be in such poor health．他的身體這么差讓我很難過.
We were surprised that she should be so stubbom．她這么固執(zhí)讓我們感到奇怪.
上述句子有時(shí)也可以用陳述語(yǔ)氣,但這僅表示所敘述的是事實(shí),而不表示講話人的情緒.
