C. Has he caught       D.   Had he caught

Answer 1

3.    D考查虛擬語氣。句意：如果他趕上了早晨的火車，他開會(huì)就不會(huì)遲到了。根據(jù)題干中的后半句"…h(huán)e would not have been late for the meeting."可知，這是一個(gè)與過去事實(shí)相反的虛擬語氣，因此前面的從句中需要用過去完成時(shí)had done。在if引導(dǎo)的虛擬語氣中，當(dāng)句中有were, should, had時(shí)，可將if省去，并把were, .should, had提到主語的前面構(gòu)成部分倒裝，故D項(xiàng)正確。
