Hewillhelpyouifyouaskhim.=Ifyouaskhim,hewillhelpyou.如果你问他，他会帮助你。2)whether替换法：if引导宾语从句时，其意为"是否"，通常可用whether替换，意义不变，而if引导条件状语从句时不能用whether替换。因此，可用whether替换的是宾语从句，不能替换的是条件从句。例如：

Iwanttoknowifyouwillgotomorrow.=Iwanttoknowwhetheryouwillgotomorrow.我想知道你明天是否去。注意：区分if的用法有着极为重要的意义，因为在条件状语从句中，主句用将来时，从句用一般现在时；而在宾语从句中，当主句是一般现在时，从句可用所需的任何时态，主句是一般过去时，从句用过去的某种时态。备考满分练一、单选题1.—Soyoumeanyoudon'tlikethebook?—________.Ilikethestoryinit,butIdon'tlikethewritingstyle.A.Notatall B.Ofcourse C.Notexactly D.You'reright2.—Whatkindofanimalsdoyoulike?—_________Iusedtoliketigers,butnowIlikelions.A.It'shardtosay.

答案以及解析一、单选题1.答案：C解析：考查情景交际。Notatall一点也不；Ofcourse当然；Notexactly不全是；You'reright你说得对。根据"Ilikethestoryinit,butIdon'tlikethewritingstyle."可知，并不完全是不喜欢这本书，C项符合语境。故选C。2.答案：A解析：考查口语交际用语。上一句是在询问对方喜欢什么动物，由下一句答语中的后半句"我过去喜欢老虎，但现在喜欢狮子。"可知对方并不知道到底喜欢什么。It'shardtosay.意为"很难说。"It'strue.意为"那是真实的。"Ithinkso.意为"我也这样认为。"Idon'tlikethematall.意为"我根本不喜欢它们。"故选A。3.答案：B解析：sense"感觉"；secret"秘诀"；course"课程"；example"例子"；根据"yourgoodgrades"和"Hardworkandcarefulness"可知问的是"你取得好成绩的秘诀是什么？"。故选：B。4.答案：A解析：考查名词。independence独立，名词；independent独立的，形容词；depend依靠，动词。动词"develop"后面缺宾语，表达"培养他们的独立性"，用名词"independence"。故选A。5.答案：C解析：考查动词辨析。remember记得；hide隐藏；remind提醒；lead带领，根据"mewhenIforgetsomethingimportant"可知，此处指忘记重要事情时，需要提醒。故选C。6.答案：C解析：句意：电影的开头很无聊。但是结尾非常棒！A.so"所以"；B.and"并且"；C.but"但是"。联系上下文，可知是转折关系。故选C。7.答案：D解析：试题分析：句意：—你还要多少时间完成法律报告？—可能再过15分钟。但是我不确定。A.Howfar多远，问距离；B.Howoften问频率；C.Howlong多久，往往用于现在完成时；D.Howsoon还要多久，往往用in+一段时间来回答。故选D.8.答案
