D解析：現(xiàn)在完成時(shí)常與recently （近來(lái)），so far （到目前為止），in the past/last + 一段時(shí)間等 時(shí)間狀語(yǔ)連用。 因?yàn)樯鲜龆陶Z(yǔ)表示的是從現(xiàn)在起往前推算的一段時(shí)間， 句中的動(dòng)作是從過(guò)去某 一時(shí)間或時(shí)刻開(kāi)始持續(xù)到現(xiàn)在的。故應(yīng)選 D。12. B解析：陳述句部分含否定詞never,簡(jiǎn)略問(wèn)句部分要用肯定式，又因 Kates是Kate has的縮寫， 故選 B13.

51、 B 解析：現(xiàn)在完成時(shí)主要強(qiáng)調(diào)過(guò)去發(fā)生的動(dòng)作對(duì)現(xiàn)在造成的影響，或過(guò)去發(fā)生的動(dòng)作還未結(jié)束， 一直持續(xù)到現(xiàn)在或?qū)?lái)，重點(diǎn)在于對(duì)現(xiàn)在的影響。這種考查難度較大，往往無(wú)時(shí)間狀語(yǔ)，需要 從上下文分析、推理才行。故上兩側(cè)根據(jù)上下文分析、推理，正確答案是B。14. B解析：現(xiàn)在完成時(shí)常與already （已經(jīng)），just （剛剛，正好），ever （曾經(jīng)），never （從來(lái)，也 不；從不），before （以前），yet （仍然）等連用。故應(yīng)選 B。15.解析：A、B、C均為非延續(xù)性動(dòng)詞，在肯定句中不與表段時(shí)間的短語(yǔ)連用，故選D16. C解析：現(xiàn)在完成時(shí)時(shí)常與 for +時(shí)間段或 since +過(guò)去時(shí)間點(diǎn) 連用 （含從句，從句過(guò)去時(shí) ）。故應(yīng) 選 C。17. B解析：現(xiàn)在完成時(shí)與一般過(guò)去時(shí)容易混淆， 就是因?yàn)樗鼈兯硎镜膭?dòng)作都發(fā)生在過(guò)去， 但二者 又有區(qū)別： 一般過(guò)去時(shí)表示過(guò)去某個(gè)時(shí)間發(fā)生的事、 存在的狀態(tài)或經(jīng)常發(fā)生的動(dòng)作， 說(shuō)話的側(cè) 重點(diǎn)在于陳述一件過(guò)去的事情，與現(xiàn)在沒(méi)有關(guān)系;現(xiàn)在完成時(shí)表示與現(xiàn)在有關(guān)系的發(fā)生在過(guò)去的動(dòng)作，它不與表示過(guò)去的時(shí)間狀語(yǔ)（如yesterday, last week, a moment ago等）連用。故應(yīng)選 B。18. C解析：現(xiàn)在完成時(shí)中，非
