3、選項(xiàng)中只有（D）是正確表達(dá)形式，故為正確答案。10.

6、.A. being there B. should there be C. there was D. there having been 解析：句意為： 要是有一聲巨響，這些動(dòng)物會(huì)受到驚嚇，這是有現(xiàn)實(shí)可能性的。"should there bel示虛擬條件句中將來時(shí)間的謂語形式，if省略所以should與there倒裝。因此B. should there be就是本題答案 。7、When Edison died, it was proposed that the American people all power in their homes, streets, and factori

13、去發(fā)生 的事情很不肯定的猜測，它表達(dá)的內(nèi)容還不能成為事實(shí)，所以藉此道歉真是不知從何說起，因此此處也不合題意。（B） had offended表示當(dāng)時(shí)已經(jīng)發(fā)生了的動(dòng)作。這是復(fù)雜條件句：apologize是現(xiàn)在，而條件句是表示對過去假設(shè)的條件句。14.
