it的用法(Ⅱ)
it可用于强调结构中。强调句结构为：It is (was)＋被强调部分＋that (who)＋其他成分。此结构强调的成分可以是主语、宾语和状语等，不能是定语或谓语，强调人时可用who或that作连词，强调其他成分一律用that。使用强调句型时，应注意以下几点：
一、强调的成分
1．强调主语时，句子的谓语动词应与被强调的主语的人称和数保持一致。
①It is I who/that am to blame.
受责备的应该是我。
②It is my mother who/that reminds me to get up on time every day.每天都是我妈妈提醒我按时起床。
2．强调宾语。被强调的宾语如果指人，可用whom代替that。
①It was an old friend that/whom he met in the park yesterday.
昨天他在公园里遇到的是一位老朋友。
②It was three books that he read in the library yesterday.
昨天他在图书馆里读了三本书。
3．强调状语。状语既可以是一个词、短语，也可以是状语从句。
①It was in the 2008 Beijing Olympic Games that Chen Xiexia won a gold medal.
是在2008年北京奥运会上陈燮霞获得了一枚金牌。
②It was three years ago that I joined the army.
我是三年前参军的。
③It was not until yesterday that I knew the news.
直到昨天我才知道那个消息。
提醒： (1)强调时间、地点、原因或方式状语时，要用that，不能用when，where，why或how等。
(2)强调的如果是原因状语从句，从句只能由because引导，不能由since，as或why引导。
(3)对not...until...结构强调，要用It is/was not until...that...这一固定句型。由于not已经前移，that后应用肯定形式。
二、强调句的疑问句式
1．一般疑问句结构：Is/Was it...that...
Was it ten years ago that he went to Beijing
他是十年前去北京的吗？
Was it on August 8th that the 29th Olympics took place
第二十九届奥运会是8月8号开幕的吗？
2．强调句的特殊疑问句结构为：疑问词＋is/was it＋that/who/whom...
When was it that you called me yesterday
你昨天是什么时候打电话给我的？
Why was it that you refused his offer of help
你究竟为什么拒绝他的帮助？
How was it that they managed to finish the work in such a short time？他们究竟是如何在这么短的时间内完成工作的？
三、强调句的其他用法
1．如果对含有“not...until...”句子中的until引导的时间状语进行强调时，需将主句中的否定副词not连同until时间状语一起提前并被强调。即：It is/was＋not until...＋that＋其他成分。
He didn’t go to bed until his mother came back.→
It was not until his mother came back that he went to bed.
直到他妈妈回来他才去睡觉。
2．强调句型用于名词性从句中及与定语从句相结合。
The question is whom it is that we can turn to for help.(名词性从句)问题是我们到底可以向谁求助。
It is in the hotel where he stayed last night that he lost his mobile phone.(定语从句)
就是在昨天晚上他待的旅馆里，他丢了手机。
3．强调句型用来强调句子中除谓语之外的其他成分，而谓语的强调则用do或did完成。
He did come here yesterday.昨天他确实来了。
(2011·重庆卷)—Have you seen the film Under the Hawthorn Tree
—Of course，I have.It was in our village________it was made.
A．that B．where
C．when D．which
解析： 句意为：——你看过电影《山楂树之恋》吗？——我当然看过。那部电影就是在我们村拍摄的。本题考查强调句型用法。被强调部分为in our village，如改为普通句型为：It was made in our village.如选B项，为where引导的定语从句，但与上句在逻辑上不符。
答案： A
(2011·四川卷)Was it on a lonely island________he was saved one month after the boat went down
A．where B．that
C．which D．what
解析： 句意为：他是不是在船沉了一个月之后在一个孤岛上被人救出来的？考查强调句。结合题干和选项看，这里用it was...that强调句结构，被强调的是地点状语on a lonely island。
答案： B
(2011·湖南卷)It’s not what we do once in a while ________ shapes our lives，but what we do consistently.
A．which B．that
C．how D．when
解析： 句意为：影响我们生活的不是我们偶尔做什么，而是我们一贯做什么。考查强调句型的用法。强调部分是句子的主语，空格部分应是强调句型中的that，故选B项。
答案： B

THE EARTH IS BECOMING WARMER
—— BUT DOES IT MATTER
During the 20th century the temperature of the earth rose about one degree Fahrenheit.That probably does not seem much to you or me，but it is a rapid increase when compared to other natural changes.So how has this come about and does it matter Earth Care’s Sophie Armstrong explores these questions.
There is no doubt that the earth is becoming warmer (see Graph 1) and that it is human activity that has caused this global warming rather than a random but natural phenomenon.
Graph 1: Temperature difference from long term average,1860～2000
All scientists subscribe to the view that the increase in the earth’s temperature is due to the burning of fossil fuels like coal，natural gas and oil to produce energy.Some byproducts of this process are called “greenhouse” gases，the most important one of which is carbon dioxide.Dr Janice Foster explains：“There is a natural phenomenon that scientists call the ‘greenhouse effect’．This is when small amounts of gases in the atmosphere，like carbon dioxide，methane and water vapour，trap heat from the sun and therefore warm the earth.
Without the ‘greenhouse effect’，the earth would be about thirty three degrees Celsius cooler than it is.So，we need those gases.The problem begins when we add huge quantities of extra carbon dioxide into the atmosphere.It means that more heat energy tends to be trapped in the atmosphere causing the global temperature to go up.”
We know that the levels of carbon dioxide have increased greatly over the last 100 to 150 years.It was a scientist called Charles Keeling，who made accurate measurements of the amount of carbon dioxide in the atmosphere from 1957 to 1997. He found that between these years the carbon dioxide in the atmosphere went up from around 315 parts to around 370 parts per million (see Graph 2)．
All scientists accept this data.They also agree that it is the burning of more and more fossil fuels that has resulted in this increase in carbon dioxide.So how high will the temperature increase go Dr Janice Foster says that over the next 100 years the amount of warming could be as low as 1 to 1.5 degrees Celsius，but it could be as high as 5 degrees.
Graph 2：Carbon dioxide content in the atmosphere,1957—1997
However，the attitudes of scientists towards this rise are completely different.On the one hand，Dr.Foster thinks that the trend which increases the temperature by 5 degrees would be a catastrophe.She says，“We can’t predict the climate well enough to know what to expect，but it could be very serious.” Others who agree with her think there may be a rise of several metres in the sea level，or predict severe storms，floods，droughts，famines，the spread of diseases and the disappearance of species.
On the other hand，there are those，like George Hambley，who are opposed to this view and believe that we should not worry about high levels of carbon dioxide in the air.They predict that any warming will be mild with few bad environmental consequences.In fact，Hambley states，“More carbon dioxide is actually a positive thing.It will make plants grow quicker；crops will produce more；it will encourage a greater range of animals—all of which will make life for human beings better.”
Greenhouse gases continue to build up in the atmosphere. Even if we start reducing the amount of carbon dioxide and other greenhouse gases，the climate is going to keep on warming for decades or centuries.No one knows the effects of global warming. Does that mean we should do nothing Or，are the risks too great？
全球在变暖——这会带来什么影响吗？
在20世纪期间，地球温度大约升了华氏1度。这个数值对你我来说很可能是无所谓的，但是跟其他自然变化相比较而言，这却是一种快速的增长。那么，这种温度的增长是怎么产生的呢？会产生什么影响呢？“关爱地球”组织的索菲·阿姆斯特朗就在探究这些问题。
毫无疑问，地球是在变暖(见表一)，而地球变暖正是人类活动导致的，并非是一种无规律的自然现象。
表1：1860～2000年长期平均温度差
所有的科学家都赞同这种观点：人们为了生产能量而燃烧化石燃料(如煤、天然气和石油等)，从而引起了地球温度的升高。这个升温过程的一些副产品就叫做“温室”气体，其中最重要的就是二氧化碳。贾尼丝·福斯特博士解释说：“有一种科学家称之为‘温室效应’的自然现象。这种现象发生在大气层中少量的气体(如二氧化碳、甲烷、水蒸气等)吸收太阳的热量，因而使地球变暖的时候。如果没有这种‘温室效应’，地球的温度将比现在的温度还要低33摄氏度左右。因此，我们需要这些气体。当我们的大气层中增加了大量额外的二氧化碳时，问题就来了。这意味着更多的热量被困在大气层中，从而引起全球温度上升。”
我们知道，在过去100～150年期间，二氧化碳的含量急剧增加。有一位名叫查尔斯·基林的科学家曾经把1957～1997年期间大气层中二氧化碳的含量作了精确的统计。他发现，在这些年里，大气层中的二氧化碳含量从315/1000 000上升到370/1000 000。(见表二)
所有科学家都接受这个数据。他们还赞同下述观点，正是由于越来越多地燃烧化石燃料导致了二氧化碳的增加。那么气温会升多高？福斯特博士说，在今后的100年里，全球变暖的量可能低到1～1.5摄氏度，但是也有可能会高达5摄氏度。
表2：1957～1977年大气中的二氧化碳含量
然而，科学家们在对待升温的态度上却是大不相同的。一方面，福斯特博士认为气温升高5度的趋势可能是一场大灾难。她说：“对于未来的气候，我们不可能作出精确的预测，但是那时的天气可能是很糟糕的。”同意她的观点的其他科学家认为，全球变暖会导致海平面上升好几米；也有人预言会出现严重的风暴、洪涝、干旱、饥荒、疫病和物种的灭绝。另一方面，还有一些人，像科学家乔治·汉布利，反对上面的观点，他们认为我们不必担心空气中会有高含量的二氧化碳。他们预言说，变暖的情况不会很严重，对环境的影响也不会太坏。
汉布利实际上是这样说的：“二氧化碳含量的增加实际上是件好事。它使植物生长更快，庄稼产量更高，还会促进动物的生长——所有这些都能改善人类的生活。”
温室气体继续在大气中聚集。即使我们开始减少二氧化碳和其他温室气体的含量，在(未来)几十年或几个世纪内，气候仍会持续转暖。没有人知道全球变暖会带来什么样的影响。这是不是意味着我们不必采取任何措施呢？还是说，这样不采取任何措施危险性会很大呢？

WHAT CAN WE DO ABOUT GLOBAL WARMING
Dear Earth Care，
I am doing a project on behalf of my school about global warming. Sometimes I feel that individuals can have little effect on such huge environmental problems.However，I still think people should advocate improvements in the way we use energy today.As I’m not sure where to start with my project，I would appreciate any suggestions you may have.
Thank you!
Ouyang Guang
Dear Ouyang Guang，
There are many people who have a commitment like yours，but they do not believe they have the power to do anything to improve our environment.That is not true. Together，individuals can make a difference.We do not have to put up with pollution.
The growth of the greenhouse gas，carbon dioxide in the air actually comes as a result of many things we do every day.Here are a few suggestions on how to reduce it.They should get you started with your project.
1．We use a lot of energy in our houses.It is OK to leave an electrical appliance on so long as you are using it—if not，turn it off! Do not be casual about this.So if you are not using the lights，the TV，the computer，and so on，turn them off.If you are cold，put on more clothes instead of turning up the heat.
2．Motor vehicles use a lot of energy—so walk or ride a bike if you can.
3．Recycle cans，bottles，plastic bags and newspapers if circumstances allow you to.It takes a lot of energy to make things from new materials，so，if you can，buy things made from recycled materials.
4．Get your parents to buy things that are economical with energy—this includes cars as well as smaller things like fridges and microwaves.
5．Plant trees in your garden or your school yard，as they absorb carbon dioxide from the air and refresh your spirit when you look at them.
6．Finally and most importantly，be an educator.Talk with your family and friends about global warming and tell them what you have learned.
Remember—your contribution counts!

关于全球变暖，我们能做些什么呢？
亲爱的“关爱地球”组织：
我正代表学校做一项关于全球变暖的课题研究。有时候我觉得，像这样一个巨大的环境问题，个人是起不了什么作用的。然而我仍认为人们应该支持改善日常能源的消耗方式。由于我还不清楚我该从哪里着手开始我的研究。我希望能得到你们的建议。
谢谢！
欧阳光
亲爱的欧阳光：
有许多人承担你这样的义务，而他们不相信自己有能力来影响环境。这种想法是不正确的，众人拾柴火焰高。我们不必去忍受污染。
空气中的温室气体，二氧化碳的增长的确是来自我们许多的日常活动。这儿有几条关于减少空气中二氧化碳含量的建议。这些建议应当能够促进你的研究。
1．在室内我们会用大量的能源。在用电器设备时你可以让它开着，如果不用就把它关掉！不要对此疏忽大意。因此，你如果不用电灯、电视、电脑等时，要把它们关掉。如果你觉得冷了，就多穿点衣服，而不要把暖气开大。
2．机动车要用大量的能源。因此，只要有可能，你就步行或骑自行车吧。
3．把罐头盒、瓶子、塑料袋和报纸回收利用起来。用新材料来做这些东西要花费大量的能源，因此，只要有可能，就买那些用回收材料制成的物品吧。
4．劝你的父母去买那些节约能源的产品，包括汽车和像冰箱、微波炉之类的小件物品。
5．在你的花园或校园里栽种树木，它们能吸收空气中的二氧化碳，还能在你观赏它们的时候使你感觉清爽。
6．最后，也最重要的是，做一个教育者。同你的家人和朋友谈一谈全球变暖的问题，并把你学到的东西告诉他们。
记住，你的贡献是很有价值的。

Global warming
在过去的一百年里，由于人类活动二氧化碳的排放量不断增加。卫星数据有助于我们了解全球气候变暖，预测未来气候的变化。
Every time we breathe out，we release carbon dioxide gas into the atmosphere.Carbon dioxide is one example of greenhouse gases—a gas that traps heat.
Over the last 100 years，the amount of carbon dioxide in the atmosphere has been steadily increasing.Most of this increase has been due to human activity，such as burning of oil and coal，or clearing of forests. Forests remove a lot of carbon dioxide from the air. However，this stored carbon is released into the atmosphere when trees are cleared or burnt.
Satellite data show that the world seems to be growing warmer. Most scientists think that there is a link between global warming and the rise in greenhouse gases.This is commonly known as the “Greenhouse Effect”．Satellites such as ESA’s Envisat help us learn more about global climate change and to predict what will happen in the future.Some instruments on Envisat produce daily global maps of greenhouse gases such as methane. Others show changes in temperature，snow，ice，lakes and forests.
Such information is vital in enforcing international agreements to cut back on greenhouse gases output.
You Can Help!
The problem seems so enormous that it may be hard for you to imagine that anything you do can really help.But it can.Here are some things you can do to help slow down global warming.
Plant trees.
Take shorter showers.
Use only energy saving bulbs in your lights.
Wear lighter clothing when it’s hot instead of turning on a fan.
Turn your lights，computers and chargers (充电器) off，and unplug (拔去……插头) them when they’re not in use.
Skip car rides and take your bike，walk，or take the bus instead.Unit 4 Section II

Ⅲ.阅读理解
Candlelight may be important in creating the perfect environment for a romantic dinner or a relaxing bath，but it could also be a dangerous one，some American scientists claim.
Researchers have found that the fumes from paraffin wax (煤油蜡)—the most common and cheapest form of candle wax—can be poisonous.They found that in spaces with limited air flow their levels can build up and，over time，they can cause health problems.An occasional candle use and its emissions will not likely affect you，said Amid Hamidi，the co author of the study at South Carolina State University.“But lighting many paraffin candles every day for years or lighting them frequently in a bathroom with limited air flow，for example，may cause problems.”
Dr Hamidi and his colleague also tested candles made from soy (大豆) and found they did not produce the dangerous things.“Although more expensive，they are healthier.They do not release harmful things.”
Candles，once used only for power cuts，have become even more popular in recent years as house design has become more fashionable.Tea lights and candles have become a necessary part of a fashionable home.People are turning to candles as a way of escaping from their busy lives and as a way of saying energy.
Dr Noemi Eiser，Medical Director of British Lung Foundation，said，“We would like to tell people that occasional use of paraffin candles should not pose any risk to their lung health.However，we would advise people to take_precautions when burning candles，such as opening a window to keep the air flow.”
Dr Joanna Owens，science information manager at Cancer Research UK，said，“There is no direct evidence that everyday use of candles can affect our risk of developing cancer.In terms of cancer，a far more significant type of indoor air pollution is second hand cigarette smoke.”

Ⅱ.阅读理解
Although it’s been two weeks since the flood hit Maple Creek，I find myself amazed more and more each day by the generous and caring people who are willing to give their time and energy to support their neighbors.
Like most people，when I woke up and learned about the coming flood that Friday morning，I knew it was going to be bad news.But I had no idea just how big it was going to be until I was driving slowly along Highway 21 in nearly knee deep water.Reporters were gathering at Maple Creek.They were from Regina，Medicine Hat and other major urban centers.It was the first time I’d ever met so many media personnel in the area.Even more than that，I was surprised by the number of people who volunteered and worked tirelessly to redirect the flood water away from the town.
Social workers from the Canadian Red Cross were there to make sure people who were forced to evacuate their homes had food and a place to stay.RCMP (皇家骑警) and firefighters worked day and night closing off streets and checking the road traffic.Even students came to help.They moved sandbags to the streets and doorways.I’d never seen such an organized team effort.There was a job for everyone，and everyone seemed to know what they had to do.
Of course，the support didn’t end when the flood water “calmed down”．The railway workers and highway construction workers put in long hours to bring the railway and road services back to the area.
It’s when a crisis hits that you see what your community is really made of.Most people never seemed to think twice about doing their part.Even people who were fortunate enough not to have their basements flooded felt the need to donate money，food and supplies to flood relief.It’s comforting to know that whenever you need help，the people in your community are there for you.
语篇解读： 在你需要帮助的时候总会有人来帮助你，这实在是令人鼓舞的事。

答案： C
Besides containing attractive flowers，trees and other plants that beautify the community，eco friendly rain gardens are healthy for the environment and the people living and working nearby.
A rain garden is not very different from a traditional garden.It is just a far more eco friendly garden.Usually it is built lower than the ground.Rain gardens make smart use of rain and storm water by temporarily (暂时地) holding water from rain and storms and letting it soak (浸入) slowly into the ground before it runs into streams or enters the public drinking water supply.
Thus，a rain garden keeps the water，allowing it to be used as needed by plants in the rain garden，rather than flowing immediately into nearby streams and going unused.The water will soak slowly into the ground within a day or two.This creates an advantage that the rain garden does not allow mosquitoes (蚊子) to breed.This is a simple，attractive，and eco friendly “green” way to treat storm water.
What’s more，planting a rain garden helps reduce pollution and improve the environment.Without using expensive machinery and chemicals，rain gardens remove harmful chemicals in the rainwater and cut down on the amount of pollution reaching streams and rivers by up to 30%.
Native plants are recommended for rain gardens because they are more used to the local climate，soil，and water conditions.They may attract local wildlife such as native birds.Water your rain garden immediately after planting and once a week，unless you have had at least an inch of rain during the week.Once the native plants establish the necessary root system，it will require little care.
Often，local governments and private businesses develop large rain gardens in their yards and in public parks as a way to improve the environment and solve flooding problems.However，you don’t need to be a professional environmental engineer to create a rain garden.As long as you’re eco conscious homeowners，you can help the environment by building smaller rain gardens in your yards.
