—Sorry. I _______ my experiment report all the morning and haven’t finished yet.

A．write	B．was writing
C．have written	D．have been writing

Answer 1

D

試題分析：考查時(shí)態(tài)。本意的關(guān)鍵詞是all the morning整個(gè)早晨，該時(shí)間狀語常常與現(xiàn)在完成進(jìn)行時(shí)連用。句意：—我想知道你是否和我一起去超市.—對(duì)不起。整個(gè)上午我都在寫實(shí)驗(yàn)報(bào)告，我還沒有寫完。根據(jù)句意說明草早上開始到現(xiàn)在一直都在寫實(shí)驗(yàn)報(bào)告。故使用現(xiàn)在完成進(jìn)行時(shí)表示過去發(fā)生的倒裝一直持續(xù)到現(xiàn)在。故D正確。
