[★常考] 主将从现：时间/条件状语从句中，主句用将来时，从句用一般现在时表将来。 [⚠️易错] while后接延续性动词，when可接瞬间或延续性动词。 状语从句 （条件） if如果；unless=if…not除非；as long as只要 I think we can solve the problem if everyone follows the three Rs! [★常考] unless=if…not，语气较强。 [⚠️易错] 条件状语从句同样遵循'主将从现'原则。 状语从句 （让步） though/although虽然；even if/though即使 While recycling is good, not everything can be recycled. [注：while此处表让步/对比] [⚠️易错] though/although不能和but连用，但可以和yet/still连用。 状语从句 （目的/结果） so that/in order that以便（目的）；so…that/such…that如此…以至于（结果） People should also try to bring their own bottles and bags so that there is less rubbish. [★常考] so+adj./adv.+that；such+a/an+adj.+n.+that。 [⚠️易错] so that可表目的（以便）或结果（以至于），需根据句意判断。 宾语从句 （that引导） that在从句中不作成分，无实际意义，口语中常可省略。 I never realized that there are so many kinds of rubbish! [⚠️易错] 以下情况that不可省略：①从句前有插入语；②多个that引导的并列从句（第二个及以后）；③it作形式宾语时。 宾语从句 （whether/if） 意为'是否'，在从句中不作成分，不能省略。 I don't know whether we should throw away or reuse this plastic bottle. [★常考] 以下情况只能用whether：①与or not连用；②介词后；③动词不定式前；④引导主语从句、表语从句。 宾语从句 （wh-词引导） 连接代词who/whom/whose/what/which；连接副词when/where/why/how。在从句中充当成分，不可省略。 Do you know why air pollution is getting worse nowadays? [★常考] 疑问词在从句中充当主语、宾语、定语或状语。 [⚠️易错] what表'什么'无范围；which表'哪一个'有范围。 宾语从句 （语序与时态） 语序：必须用陈述语序（主语+谓语）。 时态：主现从随便；主过从过去；客观真理用一般现在时。 Could you tell me why it is easy to forget a word? (陈述语序) [⚠️易错] 宾语从句不可用疑问语序！ 例：Do you know where he lives? ✓（不能说where does he live） 三、易错点警示 ⚠️ 易错点1：though/although 与 but 不能连用 【易错原因】受中文'虽然…但是…'影响，学生常在同一个句子里同时使用though/although和but。 【正确用法】英语中though/although和but只能二选一！ ✗ Although it was raining, but we still went out. ✓ Although it was raining, we still went out. / It was raining, but we still went out. 【易错提醒】至少有三分之一的同学第一次做题时会犯这个错，记住：有although就没but，有but就没although！ ⚠️ 易错点2：if 与 whether 混用 【易错原因】学生看到'是否'就想用if，忽略了只能用whether的特殊情况。 【正确用法】以下四种情况只能用whether，不能用if： ① 与or not直接连用：I don't know whether or not he will come. ② 介词后：It depends on whether we have enough time. ③ 动词不定式前：I can't decide whether to stay or leave. ④ 引导主语从句、表语从句：Whether he will come is still unknown. 【易错提醒】教材中的典型考查点，whether和or not虽然中间隔了we should…，但核心结构仍是whether…or not。 ⚠️ 易错点3：宾语从句用疑问语序 【易错原因】学生习惯性地把疑问词后的语序写成疑问句形式。 【正确用法】宾语从句必须用陈述语序（疑问词+主语+谓语+其他）！ ✗ Could you tell me where does he live? ✓ Could you tell me where he lives? ✗ I wonder why is it easy to forget a word? ✓ I wonder why it is easy to forget a word. 【易错提醒】这是中考必考点！看到宾语从句题，第一步就是检查语序——疑问词后面必须是'主语+谓语'，绝不能出现助动词do/does/did在主语前面。 ⚠️ 易错点4：so…that 与 such…that 混淆 【易错原因】不清楚so和such后面分别接什么词性。 【正确用法】 so + adj./adv. + that… The light is so bright that it causes traffic accidents. such + a/an + adj. + 可数名词单数 + that… It was such a hot day that we wanted to go swimming. such + adj. + 不可数名词/复数名词 + that… They are such beautiful flowers that everyone likes them. 【易错提醒】判断时先看中心词——中心词是形容词/副词用so；中心词是名词用such。 ⚠️ 易错点5：unless 理解成'除非'时逻辑颠倒 【易错原因】中文'除非'的理解容易和英语unless的否定逻辑搞混。 【正确用法】unless = if…not，表示'如果不…就…' You will fail unless you work harder. = You will fail if you don't work harder. 如果你不更努力，你就会失败。 = 除非你更努力，否则你会失败。 【易错提醒】unless引导的条件状语从句也遵循'主将从现'。做题时如果unless想不通，就把它换成'if…not'再读一遍，逻辑就清晰了。 四、分层练习 基础关 ★ 1. —______ you ______ to the new recycling centre yet? —No, I ______ there was one near our school. A. Did; go; didn't know B. Have; been; didn't know C. Have; gone; haven't known D. Did; go; haven't known 【答案】B 【解析】yet是现在完成时标志词，用Have…been；'不知道有回收中心'是过去的动作，用一般过去时didn't know。 2.
