【主题导入】
Nature has provided us with many kinds of resources.Almost
everything we use in our everyday life comes from Nature.The food we eat，
the water we drink，the clothes we wear，the concrete and bricks to build our houses，the materials to make bikes we ride，etc，all come originally from Nature.
People have been making use of these natural supplies for thousands of years.With the development of technology and the increase of the population，the amount and range of materials taken has increased.It is estimated that this trend will continue in the years to come.
However，natural resources are not inexhaustible.Some resources are already nearly used up.For example，the end of the world's fuel is already within sight.Such an essential daily item as water is in short supply in many parts of the world.We can no longer thoughtlessly use the many resources provided by Nature.We must learn to conserve what remains.

A Journey of Discovery
The captain① of the ship，the Beagle，wanted someone who would “profit by the opportunity of visiting distant countries yet little known” [1].The person who answered the call② was not the captain's first choice.It was a young man who had left medical school③ without completing his degree④.What's more⑤，he had recently received a letter from his father predicting⑥ that he would be “a disgrace to yourself and all your family” .Despite⑦ all this，his adventures⑧ on this ship would lead to⑨ one of the most important scientific discoveries⑩ of all time.
[1]本句为主从复合句，其中who引导的定语从句，修饰先行词someone。
The young man in question ，Charles Darwin，was a geologist and naturalist，fascinated by rocks，plants and animals.He left England on the ship，the Beagle，in 1831.The journey gave him the chance to study various living things in their natural environments. After Darwin had spent some time in South America，his room on the ship was crowded with samples of the plants and animals he had collected．[2].As he studied these，he asked himself the question: how did different species come to exist ？
[2]本句为主从复合句，其中划黑体字部分为省略了连词的定语从句，修饰先行词samples。
At that time，people believed that all species had appeared on Earth at the same time ，and had not changed since.But Darwin began to think differently.He noticed that some species of animals were very similar to each other. Maybe animals evolved as they adapted to their changing environments [3] It was just an idea，but enough to inspire Darwin to look for more evidence.
[3]本句中as引导的时间状语从句。
When the Beagle reached the Galápagos Islands in 1835，Darwin saw a variety of new species，but it was the birds that interested him the most [4].Darwin noticed that there was a difference between the finches on each of the islands.It seemed their beaks had evolved according to21 what food was available22 on that particular23 island.
[4]本句为强调句型，强调句子的主语the birds。
Darwin suspected24 that the finches had evolved from a common ancestor，which had arrived on the islands a long time before [5].Over time25，it had slowly evolved into many new species.And that was the answer to26 how new species of plants and animals came to exist: they evolved from earlier ancestors.
[5]本句为主从复合句，其中which引导的定语从句，修饰先行词a common ancestor。
It was a completely new idea27—a theory of evolution.Darwin explained this theory in his book，On the Origin of Species.It was not published until 1859 and immediately caused a storm28. Many people refused to believe that living things，including humans，had evolved from lower forms of life.They were shocked. But Darwin's scientific studies were so convincing 29that more and more people started to believe his theory [6].
[6]本句中含有so...that...，that引导结果状语从句。
Today，On the Origin of Species is regarded as30 one of the most important works ever written.It has changed ideas about life on Earth forever.And it all began with31 the journey on the Beagle.
——译文参考——
探索之旅
“小猎犬” 号船长需要一个人，他能“有机会访问遥远但鲜为人知的国家且从中获利” 。响应号召的人不是船长的首选。是一个没有完成学位就离开了医学院的年轻人。而且，这位年轻人最近收到了父亲的一封信，信中预言他将是“你自己和全家的耻辱” 。尽管如此，他在这艘船上的冒险将导致有史以来最重要的科学发现之一。
这位年轻人就是查尔斯·达尔文，他是一位地质学家和博物学家，对岩石、植物和动物着迷。1831年，他乘“小猎犬” 号离开英国。这次旅行使他有机会研究环境中的各种生物。达尔文在南美呆了一段时间后，他在船上的房间里挤满了他收集的动植物样本。当他研究这些样本的时候，他问了自己一个问题：不同物种是如何产生的？
当时，人们认为地球上所有的物种都是同时出现的，从那时起就没有改变过。但达尔文开始有不同的想法。他注意到有些动物彼此非常相似。也许动物是随着适应环境的变化而进化的？这只是一个想法，但足以激励达尔文去寻找更多的证据。
1835年，当“小猎犬” 号到达加拉帕戈斯群岛时，达尔文看到了许多新物种，但最令他感兴趣的是鸟类。达尔文注意到每一个岛上的雀鸟都有区别。它们的喙似乎是根据那个岛上的食物进化而来的。
达尔文怀疑这些雀鸟是从一个共同的祖先进化而来的，这个祖先很久以前就来到了这些岛屿。随着时间的推移，它慢慢进化成许多新物种。这就是植物和动物新物种如何产生的答案：它们是从早期祖先进化而来的。
这是一个全新的概念——进化论。达尔文在《物种起源》一书中解释了这一理论。这本书直到1859年才出版，并立即引起了一场风暴。许多人拒绝相信包括人类在内的生物是从低级生命形式进化而来的。他们很震惊。但是达尔文的科学研究是如此令人信服，以至于越来越多的人开始相信他的理论。
今天，《物种起源》被认为是有史以来最重要的著作之一。它永远改变了人们对地球生命的看法。这一切都是从“小猎犬” 号的旅程开始的。

The Secret Language of Plants
Talking plants have long been a thing of myths and legends.Many cultures have stories of talking trees that give advice①as well as② warnings to people. Alexander the Great and Marco Polo were said to have visited such a tree in India. [1]And in some modern stories，such as③ the film Avatar，trees can communicate with④ animals and people．
[1]句中的be said to...意为“据说……” ，可改为It is / was said that...。
With us long believing that talking plants are fantasy，new research has revealed⑤something amazing [2]: it appears that plants can communicate after all.
[2]句中with us long believing...为with复合结构，在句中作状语。
It has been known for some time that plants use chemicals to communicate with each other.This happens when a plant，say⑥ a bean plant，gets attacked⑦ by insects. The plant releases tiny amounts of ⑧ chemicals from the leaves that are being eaten. [3] This is like a warning，or a call for help⑨：“I'm being attacked！” When another bean plant detects the chemicals from its injured neighbour，it starts to release its own，different chemicals.Some of these chemicals drive insects awayB10.Others attract insects—the wasps! The wasps kill the insects that are eating the bean plants. Scientists hope to learn more about this plant warning system ，so that we can use it to grow crops without pesticides. [4]
[3]句中的that从句为定语从句，修饰先行词the leaves，that在从句中作主语。
[4]so that引导结果状语从句，其前常有逗号和主句隔开，这也是和so that引导的目的状语从句的区别之一。
More surprisingly ，plants also use sound to communicate.People can't hear these sounds，but plants are making them.Some plants make noises with their roots.Corn and chilli plants do this.They also “listen” to the noises from other plants.A chilli plant can tell if a neighbouring plant is helpful，or unfriendly. Some trees make clicking noises when there is not enough water，indicating drought is arriving. [5]
[5]句中when引导时间状语从句，drought is arriving是省略了连词that的宾语从句，现在分词短语indicating...在句中作伴随状语。
Most surprisingly of all ，plants have an amazing system of communication that can link nearly every plant in a forest.Scientists call this system the“wood wide web” .It is in some ways similar to the Internet we use. While the Internet is a worldwide network of computers linked by cables and satellites , the wood wide web is linked underground by fungi. [6]This fungal network links the roots of different plants to each other.Using the wood wide web，plants can share information and even food with each other.For example，some pine trees can send food to smaller pine trees to help them grow.But just like our own Internet，the wood wide web has its own version of“cybercrime” .Plants can steal food from each other，or spread 21 poisons to attack other plants.Perhaps one day scientists will learn how to create a “firewall” to help prevent these attacks within the wood wide web.
[6]句中while...引导的是让步状语从句，linked by cables and satellites是过去分词短语在句中作后置定语。
Scientists are learning more every day about the secret ways in which plants talk to each other. [7]Who knows Maybe one day we will know enough about plant communication to be able to “talk” with them ourselves.
[7]句中in which引导定语从句，修饰先行词ways，way作先行词且在定语从句中作状语时，常用that或in which引导定语从句，也可省略。
——译文参考——
植物的秘密语言
能说话的植物早就成了神话传说。许多文化中都有这样的故事：会说话的树既给人忠告，也给人警告。据说亚历山大大帝和马可波罗在印度参观过这样一棵树。在一些现代故事中，比如电影《阿凡达》，树木可以与动物和人交流。
长期以来，我们一直认为会说话的植物是幻想，新的研究揭示了一个惊人的现象：好像植物竟然可以交流。
一段时间以来，人们都知道植物使用化学物质相互交流。当一种植物，比如一种豆科植物，被昆虫攻击时，就会发生这种情况。这种植物从正在被吃掉的叶子中释放出微量的化学物质。这就像是一个警告，或是呼救：“我被攻击了！” 当另一种豆科植物从它受伤的邻居身上检测到这些化学物质时，它开始释放自己的不同化学物质。其中一些化学物质能驱走昆虫。另外一些化学物质能吸引昆虫——黄蜂！黄蜂杀死吃豆科植物的昆虫。科学家们希望更多地了解这种植物预警系统，以便我们能够利用它来种植没有杀虫剂的作物。
更令人惊讶的是，植物也用声音来交流。人们听不到这些声音，但是植物在制造这些声音。有些植物的根发出噪音。玉米和辣椒可以做到这一点。他们也“听” 来自其他植物的噪音。辣椒植物能分辨邻近的植物是有益的还是不友好的。有些树在没有足够的水时发出咔嚓声，说明干旱即将来临。
最令人惊讶的是，植物有一个惊人的通讯系统，几乎可以连接森林中的每一种植物。科学家称这个系统为“木维网” 。它在某些方面类似于我们使用的互联网。因特网是一个由电缆和卫星连接的计算机组成的世界性网络，而“木维网” 则是由真菌连接在地下的。这种真菌网络把不同植物的根相互连接起来。利用“木维网” ，植物可以彼此共享信息甚至食物。例如，一些松树可以向较小的松树发送食物来帮助它们生长。但就像我们自己的互联网一样，“木维网” 也有自己版本的“网络犯 罪” 。植物可以互相偷取食物，或者传播毒药攻击其他植物。也许有一天，科学家们将学习如何创建一个“防火墙” ，以帮助防止在“木维网” 中发生这些攻击。
科学家们每天都在学习更多关于植物相互交流的秘密方式。谁知道呢？也许有一天，我们会对植物的交流有足够的了解，能够自己和它们“交谈” 。

写出下列句子中的两个动作，哪个动作先发生
1．(教材P66)It was a young man who had left medical school without completing his degree.____________
2．(教材P66)What‘s more，he had recently received a letter from his father predicting that he would be“a disgrace to yourself and all your family”．____________
3．(教材P67)At that time，people believed that all species had appeared on Earth at the same time，and had not changed since.________________
4．(教材P67)It seemed their beaks had evolved according to what food was available on that particular island.____________
5．(教材P68)Darwin suspected that the finches had evolved from a common ancestor，which had arrived on the islands a long time before.____________
had left
had received
had not changed
had evolved
had arrived
1．表示在过去某一时刻或动作以前完成了的动作，也可以说过去的时间关于过去的动作。即“过去的过去” 。可以用by，before等介词短语或一个时间状语从句来表示，也可以用一个表示过去的动作来表示，还可能通过上下文来表示。
By nine o'clock last night，we had got 200 pictures from the spaceship.
到昨晚9点钟，我们已经收到200张飞船发来的图片。
2．表示由过去的某一时刻开始，一直延续到过去另一时间的动作或状态，常和for，since构成的时间状语连用。
I had been at the bus stop for 20 minutes when a bus finally came.
当车来的时候，我在车站已等了20分钟。
He said he had worked in that factory since 1949.
他说自从1949年以来他就在那家工厂工作。
3．过去完成时常常用在told，said，knew，heard，thought等动词后的宾语从句(或间接引语)中，这时从句中的动作发生在主句表示的过去的动作之前。
He said that he had known her well.
他说他很熟悉她。
I thought I had sent the letter a week before.
我认为我一星期前就把信寄出去了。
4．状语从句：在过去不同时间发生的两个动作中，发生在前，用过去完成时；发生在后，用一般过去时。 如： when，before，after，as soon as，till/until引导的复合句。
When I woke up，it had already stopped raining.
我醒来时雨已停了。
She didn't go to bed until she had finished her work.
她直到把工作做完之后才睡觉。
【微点拨】 如果两个动作紧接着发生，则常常不用过去完成时，特别是在包含before和after的复合句中，因为从句的动作和主句的动作发生的先后顺序已经非常明确，可以用一般过去时代替过去完成时。
After he arrived in England，Marx worked hard to improve his English.
马克思到达英格兰之后，努力提高他的英语水平。
5．动词think，want，hope，mean，plan，intend等用过去完成时来表示过去未曾实现的想法、希望、打算或意图等。
They had wanted to help but could not get there in time.
他们本来打算去帮忙，但没有及时赶到那里。
We had hoped to be able to come and see you.
我们本来希望能来看看你。
6．过去完成时还可用在hardly...when...，no sooner...than...，It was the first (second，etc) time (that)...等固定句型中。
Hardly had he begun to speak when the audience interrupted him.
他刚开始演讲，听众就打断了他。
No sooner had he arrived than he went away again.
他刚到就又走了。
It was the third time that he had been out of work that year.
这是他那一年第三次失业了。
7．表示与过去相反的虚拟语气if从句中，常用过去完成时。

日志
[文体指导]
日志是用来记叙一天中所发生的最有趣的事情和对事情的感受或对将来的打算等。
日志可分为记事、议论、描写及抒情等。日志的人称和时态：日志是记叙自己亲自经历的一些重要的、有意义的事情。因此在写作时应注意必须用第一人称进行叙述。另外，由于日志所记叙的事情已经发生，所以整篇日志的时态常用过去时态。
写作技巧：
1．无论是哪种形式的日志，写作前都要注意仔细审题，抓住要点，理清叙述的顺序。
2．日志应以时间发生的先后顺序来展开，并且要简明扼要，条理清楚，写出真实感。
3．书写时应注意卷面整洁，字迹清楚。

We visited the zoo on the moon，and we saw various creatures in the space，which were quite different from those on the earth．
【微点拨】 在写作过程中，可以根据提纲和要点构造能表达基本含义的简单句。要保证所用词汇和句式正确，然后进一步把某些简单句润色成为含有从句的复合句或特殊句式，在句与句之间增加一些衔接性的过渡词汇如：after getting off the spaceship，And...” 等，以使文章更加连贯、流畅。
[连句成篇]
Today I travelled to the moon by spaceship，which I had been dreaming of.It took us two hours to get to our destination.We wore space suits，which made us as comfortable as we were on the earth.As we had been told，we found it was rather easy to jump high on the moon，because the gravity of the moon is much lower than that of the earth.We visited the zoo on the moon，and we saw various creatures in the space，which were quite different from those on the earth.And in the science and technology museum，we learned about the history of the moon's development.It is also a history of how human beings conquered the moon.The whole journey was pretty wonderful．
