Summer sees the mountains turn bright green with growing rice. During autumn, these same mountains are gold, and in winter they are covered in sheets of white frost. These are the colours of the Longji Rice Terraces.These terraces were built by the local Zhuang and Yao people, (1) to whom Guangxi is home. (2) Starting in the Yuan Dynasty, work on the terraces took hundreds of years, until its completion in the early Qing Dynasty. Reaching as far as the eye can see, these terraces cover tall mountains, often from the bottom to the very top.So why did these people go to so much trouble to turn the entire mountains into terraces? Firstly, there are few large, flat areas of land in the region. Building the terraces therefore meant (3) that they could increase the areas in which they could grow rice. Secondly, (4) although the region has plenty of rain, the mountains are steep and the soil is shallow. The flat terraces catch the rainwater and prevent the soil from being washed away.But perhaps (5) what is most significant is the way in which people have worked in harmony with nature to make these terraces and grow rice. The terraces are cleverly designed, with hundreds of waterways that connect with each other. During the rainy season, (6) it is along these waterways that rainwater moves down the mountains and into the terraces. The sun heats the water and turns it into vapour. This forms clouds (7) from which rain falls down onto the mountain terraces once again. These terraces also provide a perfect environment for birds and fish, (8) some of which feed on insects that can harm the rice crops.Although modern technology could help produce more crops, these terraces still mean a lot to the people (9) for whom traditions hold much value. This knowledge is passed down through families, (10) which means that new generations continue to use ancient methods of agriculture to maintain the terraces. Today, the Longji Rice Terraces attract thousands of visitors (11) who come to admire this great wonder created by people and nature working together.Developing ideas一、知识点：1 if引导条件状语从句；that引导宾语从句作see的宾语。

专题六 状语从句◆时间状语从句的考查要点1．before 引导的从句中不用否定式谓语。
常用如下句型：It will be long before...(得过好久才……)It will not be long before...(过不了多久就……)It was long before... (过了好久才……)It was not long before... (过了不久就……)2．since 后面所用动词不同，该动词所表示动作持续时间的计算方法也不同。
⎩⎪⎨⎪⎧ since ＋瞬间动词过去式从该动作发生时算起since ＋持续性动词过去式从动作结束时算起It is two years since he joined the army.他参军两年了。
It is two years since he smoked.他戒烟两年了。
类别作用 例句 as as 表示“当……的时候”，往往和when/ while 通用，但它着重强调主句与从句的动作或事情同时或几乎同时发生。
She came up as I was cooking.(同时) The runners started as the gun wentoff.(几乎同时)when (at or during the time that )既可以表示在某一点的时候，又可表示在某一段时间内，主句与从句的动作或事情可以同时发生也可以先后发生。
It was raining when we arrived.(指时间点) When we were at school ，we went to the library every day.(在一段时间内) whilewhile 意思是“当……的时候”或“在某一段时间里”。
主句中的动作或事情在从句中的动作或事情的进展过程中发生，从句中的动词一般要用延续性动词。
在when 表示a period of time 时，两者可以互换。
Please don’t talk so loud while others are working. He fell asleep while/when reading. Strike while the iron is hot. (用as 或when 不可，这里的while 意思是“趁……”) 4.引导时间状语从句的连接词除上述外还有：(1)till ，not...until...，untilDon’t get off the bus until it has stopped.He waited for his father until/till it was twelve o’clock.(2)hardly/scarcely...when ，no sooner...than 表示“刚……就”We had hardly got/Hardly had we got into the country when it began to rain. No sooner had he arrived/He had no sooner arrived than she started complaining.(3)directly ，immediately ，the moment ，the minute ，the instant ，as soon as ，意为“一……就”He made for the door directly he heard the knock.The moment he saw his mother ，he burst into tears.(4)each time ，every timeEach time he came to my city ，he would call on me.题组训练1用适当的连词填空1．If a lot of people say a film is not good，I won’t bother to see it，or I’ll wait until/till it comes out on DVD.2．They rushed in while we were discussing problems.3．One Friday，we were packing to leave for a weekend away when my daughter heard cries for help.4．It was April 29,2001 when Prince William and Kate Middleton walked into the palace hall of the wedding ceremony.5．As is reported，it is 100 years since Qinghua University was founded.6．He had no sooner finished his speech than the students started cheering.◆让步状语从句的考查要点1．although与though可以引导让步状语从句，不能与but连用，但可以与yet连用。
Although/Though they are poor，(yet)they are warmhearted.2．even if或even though引导让步状语从句，表示“即使”、“纵然”，用来使人注意下文所强调内容的性质。
I’ll get there even if/though I have to sell my house to get enough money to go by air.3．no matter后接上who，what，where，how等疑问词引导让步状语从句，也可以在这类疑问词后面加上ever构成whoever，whatever，wherever，however等。
但在引导名词性从句时只能用whever类词。
Don’t trust him，no matter what/whatever he says.I will eat whatever you give me.No matter how hard the work is，you’d better try to do it well.4．as也可以引导让步状语从句，需将从句中的表语、状语以及谓语中的实义动词提前至从句句首，引起倒装；作表语的单数可数名词前如有冠词，冠词需省去。
though引导的从句也可以倒装，但although引导的不可以。
Child as(though) he is，he knows a lot.Much as I like it，I won’t buy.Try as he would，he couldn’t lift the heavy box.5．while也可以引导让步状语从句，表示“尽管”，比though/although语气弱。
while 引导的让步状语从句一般要位于句首。
题组训练2用适当的连词填空1．It was a nice meal，though a little expensive.2．While/Though/Although volleyball is her main focus，she’s also great at basketball.3．Frank insisted that he was not asleep although/though I had great difficulty in waking him up.4．Although/Though regular exercise is very important，it’s never a good idea to exercise too close to bedtime.5．While/Though/Although all of them are strong candidates，only one will be chosen for the post.6．We’ll make a trip ev en_if/though the weather is bad.◆原因状语从句：because，for，as，since，now that1．表示不知道的原因时用because，即说话人认为听话人不知道，因此because从句是全句最重要的部分，通常它被置于主句之后。
You want to know why I’m leaving？I’m leaving because I’m fed up with the boss. for虽然表示不知道的原因，但其语气较because要弱得多，是可说可不说的话，它只能置于主句之后，这时，for是并列连词。
如果不是因果关系，而是对前面主句的内容加以解释或推断时，只能用for。
It’s morning now，for the birds are singing.(很显然，鸟叫不可能是“现在已是早上”的原因)。
2．表示已经知道的原因时用as或since，即某种原因在说话人看来已经很明显，或已为听话人所熟悉，因此它是句中不很重要的部分。
since要比as正式一些，它们通常被置于语句之前，但有时却相反。
Seeing all of the children already seated，he said，“Since everyone is here，let’s start.”3．下列情况下只能使用because：①在回答why的问句时；②在用于强调句型时；③被not所否定时。
◆地点状语从句：where，wherever等Make a mark wherever you have any questions.We will go where the Party directs us.◆目的状语从句：that，so that，in order that注意：目的状语从句中的谓语动词常与情态动词连用，否则可能是结果状语从句，不可置于句首。
He got up early so that he could catch the early train.◆结果状语从句：that，so that，so...that...，such...that...注意：so＋形容词/副词＋that从句；such＋名词＋that从句。
