本节课程的意义及作用 1.时间状语从句 2. 条件状语从句 3. 比较状语从句 4. 结果状语从句 5. 原因状语从句 6. 目的状语从句 7. 让步状语从句 8.方式状语从句 9. 地点状语从句
接状语从句（上）的内容5. 原因状语从句(1)原因状语从句通常由because, since, as引导。because常回答why引导的疑问句，该从句一般位于主句后；since比as正式，两者不回答why引导的问句，而且其从句一般放在句首。如：He didn’t cme t schl because he was ill.As it is raining, we shall nt g the z.Since yu can’t answer the questin, I’ll ask smene else.(2)because表示直接原因，语气最强。because引导的原因状语从句多放在主句之后。回答由why提出的问题，只能用because。as和since语气较弱，一般用来表示明显的原因。由as和since引导的原因状语从居多放在句首。
考点链接(3)because和s不能同用在一个句子里。（4）fr是并列连词，引导的句子不置于句首，是一种非直接的、随便附加说明的理由或推断。The il must be ut, fr the light went ut.（5）because和becuse f 也有明显的区别。because后面要跟从句，而because f 后面要跟名词短语。He is late fr schl because it rains heavily. He is late fr schl because f the heavy rain.
考点链接 6. 目的状语从句(1)目的状语从句通常由 s that, in rder that引导。例如：We started early s that we culd catch the first train.He studies hard s that he culd wrk better in the future.We used the cmputer in rder that we might save time.(2)s that既可引导目的状语从句，又可引导结果状语从句。区别这两种从句的办法有两个：1)目的状语从句里往往带有情态动词can, culd, may, might等。2)从意思上看，目的状语从句往往表示的目的很明确。例如：Speak clearly s that they may understand yu. （目的状语从句）Jack is badly ill s that he has t rest. (结果状语从句)
考点链接(3）结果和目的状语从句还要注意以几点：①　s … that用在单数可数名词前，s ＋ 形容词 ＋ a ＋ 名词 ＋ that，如： She is s beautiful a girl that everyne likes her 或用 such ＋ a ＋ 形容词 ＋ 名词 ＋ that, 如： She is such a beautiful girl that everyne likes her ②　在不可数名词或可数名词复数前只能用 such， 如： It is such gd weather we want t g fr a picnic 又如： They are such gd players that they shuld win the game.　
考点链接③　在much， many， few， little 之前只能用s， 如： I have s little mney that I can't buy it ④　s … that 之间只有形容词时，则不能用 such， 如： It is s gd that I want t buy ⑤　s that 其后接从句，如： I gt up earlier s that I culd catch the first bus
考点链接7. 让步状语从句(1)让步状语从句通常由thugh／ althugh（虽然），even thugh（尽管），even if(即使），whever（无论谁），（无论怎样），whatever（无论什么）等连词引导。例如：Thugh he is yung, he knws a lt.Althugh I am tired, I must g n wrking. Even if he is pr, she lves her husband.
考点链接 (2)because不能与并列连词s，thugh ／althugh不能与but同时在句中使用。如： She was late fr schl because she missed the bus． =She missed the bus，s she was late fr schl． 我们不能说：Thugh it was raining hard, but he still went ut.应该说：Thugh it was raining hard, he still went ut.或It was raining hard, but he still went ut.
考点链接8.方式状语从句引导方式状语从句的有as（按照）等。如： I will d it as yu tell me．我将照你说的做。方式状语中要注意的是as (连词)与 like (介词)的区别。 as 作为连词其后接从句，如： Please d it as I did it 但后面的句子常作省略，如： Please d it as I 而 like 是介词，其后要接的是宾语，如： Please d it like me9. 地点状语从句 地点状语从句常常由where来引导。例如： G where yu like. Where there is a will, there is a way.
考点链接1. ［误］ While the clck struck ten, all the lights went ut. ［正］ When the clck struck ten, all the lights went ut. ［析］ while是强调两个动作在同时进行中，如：While I am ding my hmewrk, my father is reading a newspaper. 而这里的when是"正当某某时刻"，"就在这一时间点上"，其重点强调在某一特定时刻某动作的发生。 2.［误］ While I was walking alng the street yesterday, I met an ld friend. ［正］ When I was walking alng the street yesterday, I met an ld friend. ［析］ 这里用when表达在一个动作的进行中，另一个动作突然发生了。正在进行的动作用一进行时态，而突然发生的动作用一般时态。
难点链接3.［误］ While I heard the bad news I felt sad. ［正］ When I heard the bad news, I felt sad. ［析］ while不能表达一点儿的时间，即瞬时某一时间点。 4.［误］ Fr there is n light in the classrm. The students must have gne hme. ［正］ The students must have gne hme, fr there is n light in the classrm. ［析］ 由fr引出的原因状语从句在使用时要注意不能将该从句置于句 首，而应置于主句之后，并在主句与从句之间加一逗号。更要注意的是because, as, since与fr 4个表示原因的连词中because是因果关系，是最强的一个，而fr是最弱的一个。有些语法书中干脆把fr叫做并列连词
考点链接5.［误］ She sang when she walked alng the dark street. ［正］ She sang as she walked alng the dark street. ［析］ as用于句中时，其要点是强调两个动作的同时进行。这里用when虽然不能讲是语法上的错误，但则看不出来小女孩因独自走黑暗的街道因害怕而唱歌的心情。 6.［误］ I finished my hmewrk until twelve 'clck last night. ［正］ I didn't finished my hmewrk until twelve 'clck last night. ［正］ I did my hmewrk until twelve 'clck last night. ［析］ until用在句中时其含义是某一动作一直持续到某时结束，那么句中的动词则一定要用持续性动词，如果要用瞬间，或截止性动词时一定要用否定句式。因截止性动作的否定式应看作是持续性的动作。如离开leave是瞬间动作，因一出门即为离开了，而不离开则是长时间的。
难点链接7.［误］ I have studied English when I was twelve. ［正］ I have studied English since I was twelve. ［析］ since引出的时间状语从句是表达了一个时间点，而这个时间点是主句动作的启始点，所以主句一般要用完成时态。 8.［误］ Because he didn't study hard, s he didn't pass the exam. ［正］ He didn't pass the exam because he didn't study hard. ［析］ because 与 s在英文中两者不能并用的，只能在句中用9.［误］ Befre I d nt give yu the answer, I'll ask yu sme questins. ［正］ Befre I give yu the answer, I'll ask yu sme questins. ［析］ 这种错误是由于受中文的影响。在中文中可以讲"我没给你答案前"。而英文用了befre就不要再用否定句了。
难点链接10.［误］ He was such excited that he culd nt speak. ［正］ He was s excited that he culd nt speak. ［析］ s与such的用法可以分为四种情况，①用于单数可数名词之前，其格式是such+不定冠词+形容词+单数可数名词，如：It is such a beautiful bk that every child likes it. 也可以用s, 其格式是s+形容词+不定冠词+单数可数名词，如：It was s beautiful a bk that every child likes it. ②在不可数名词前或可数名词复数前这时只能用such, 如：It is such gd weather that we want t swim. 又如：They are such gd students that they can pass the exam easily. ③在few, little， much, many 这4个字前只能用s而不能用such, 如：I have s much mney that I can buy everything I want. ④当that前只有形容词或副词时，这时只能用s, 如：She is s beautiful that every ne likes her. He ran s fast that I culdn‘t keep up with him
考点链接11.［误］ He gt up earlier this mrning s as t that he culd catch the first bus. ［正］ He gt up earlier this mrning in rder t catch the first bus. ［正］ He gt up s earlier that he culd catch the first bus. ［析］ s…that与s that的用法有相同之处，那就是其后接从句，而in rder t 其后要接不定式，即动词原形。12.［误］ I want t buy same stamp that yu have. ［正］ I want t buy the same stamp as yu have. ［析］ the same…as (that)这是个固定用法，在same前的定冠词是不能少的。而the same…that意为"我要的就是那一个"。而the same…as为"要的是和……一样的东西"。
