9.The Middle East countries and other world powers have been facing major political tensions which have made the stability of the crude oil prices very unpredictable.Each day the prospect(前景)of oil prices has become more and more unclear.
Water fuel has been developed as an alternative source of fuel which has fast become popular around the world.This exciting technology has various advantages.More than 70percent of the Earth is covered with water and this fuel source does not produce any harmful pollutants or dangerous emissions(散发物)either.They in fact also double the mileage(里程)of the cars that are powered by them.
Water fuel technology has been known to be the best additional form of fuel source for petrol or other fuel sources.However,any claim that this technology can be only an additional source and not a replacement is totally incorrect and misleading.such ideas have been implied by those who look down on this technology,On the contrary,this technology has numerous benefits such as it does not produce any harmful emissions which can affect the climate changes.It further helps to reduce the level of noise produced by the engines.
Various researches reflect that running costs on fuels for automobiles can be easily saved up to 40percent with the help of water cell technology.This technology can easily work on various cars powered by gas.It can also be used for trucks,vans and other vehicles.The tap water can also be easily used directly and you do not need any special water that is specially treated to be used for this purpose.You can easily find a lot of details so that you can adapt your car to use the technology.

64.We can learn from the first paragraph that the price of oilC,
A.has been rising for a long time    B is going down at present
C is unstable for political reasons   D is decided by powerful countries
65.Water fuel technology has many advantages EXCEPT thatD.
A water fuel will not pollute the environment
B it is very simple to get such kind of fuel
C cars powered by the fuel can be used longer
D it has already been popular around the world
66.People holding the opposite idea think thatB.
A the world climate won't be influenced by fuel
B petrol can't be completely replaced by water fuel
C the engines will give out less noise than before
D water fuel can't act as an additional source for gas
67.What is the best title for the text?A
A.Water Fuel-Becoming a Reality Now        B.Water Fuel-Lower Cost
C.Water Fuel-a Long Way to Go              D.Water Fuel-a Safer Choice.

19.Since the pre-historic times,man has had an urge to satisfy his needs.Be it hunger,shelter or search for a mate,he has always controlled the situations to his advantage.Probably this might be the reason why we humans are the most developed of all living species on the earth.As we climbed the steps of development,we somehow left behind common sense and logical thinking--we forgot that we have stopped thinking ahead of time.
If you are hungry,what do you do?Get a piece of your favorite meal and stay quiet.Just like your stomach,even your mind is hungry.But it never lets you know,because you keep it busy thinking about your dream lover,favorite star and many such things.So it silently began to care about your needs and never let itself grow.When mind looses its freedom to grow,creativity gets a full stop.This might be the reason why we all sometimes think"What happens next?","Why can't I think?""Why am I always given the difficult problems?"Well,this is the result of using our brain for thinking of not-so-worthy things.
Hunger of the mind can be actually satisfied through reading.Now why reading and not watching TV?Because reading has been the most educative tool used by us right from the childhood.Just like that to develop other aspects of our life,we have to turn to reading.You have innumerable number of books in this world which will answer all your"How to?"questions.The interesting part of the book is stored in your mind as a seed.Now this seed is unknowingly used by you in your future to develop new ideas.The same seed,if used many times,can help you link and relate a lot of things,of which you would have never thought in your wildest dreams!This is nothing but creativity.More the number of books you read,your mind will open up like never before.
72.What is the function of the first paragraph?B
A.To show humans are the most developed.
B.To introduce the topic of the passage.
C.To indicate people have different needs to satisfy.
D.To explain why people need to read.

B.When freedom is lost,creativity gets a full stop.
C.When mind stops growing,creativity fully stops.
D.When growing is lost,creativity gets a flail stop.
74.The paragraph following the passage is probably aboutB.
A.how the pre-historic man feeds his mind
B.what other advantages reading brings
C.how to develop creativity
D.how to satisfy your mind by watching TV

20.Film cameras and digital cameras work in a similar way.
Film cameras
After all,a film camera is basically a light-proof (不透光的) box.It has a lens (镜头) system to focus light onto the film at the back of the camera.
Let's suppose that we are outside on a beautiful summer day trying to take a picture of the family dog.We are using a film camera.We finally get the dog to lie still.You point the camera at him.What happens?Light goes into the camera lens and hits the shutter.In other words,nothing happens yet.Now let's say that the dog looks really cute and you decide to snap a picture.What happens?When you press the button,the shutter open for a very short period of time.A small amount of light passes through and hits the film at the back of the camera.This creates an upside-down and reversed (反向的)image on the film.
    When you finish the roll of the film,you can take it to the photo shop to develop it and you will have a great picture of your dog!
    Cameras come with different lens lengths.Why does it matter?Many small cameras have shorter focal lengths,which means that there is a small distance between the lens and the place where the light focuses at the back of the camera.This gives you a large view of the area you are taking a picture of.Lenses with a long focal length show a smaller area but allow you to focus on distant objects and make them bigger.They are often called telephoto lenses.A good example of a long focus lens is one that is used by sports photographers to get photos of football players as if they were standing right beside them.
Digital cameras
    In digital cameras,the light falls not on film but onto a sensor (传感器)called a CCD (Charge Coupled Device).This digitally converts(转变) light and colour into a digital information or pixels (象素).The CCD is the heart of any digital camera and usually the most expensive part----depending on how good it is.
67.Which of the following statements is TRUE?C
A.Both digital and film cameras focus light onto the film.
B.All cameras have a sensor.
C.Digital cameras and film cameras have something in common..
D.Small cameras usually have longer focal lengths.
68.In the"Film cameras"part,you fail to take the picture of the dog becauseC.
A.light goes into the camera lens and hits the shutter
B.you haven't aimed the camera at the dog
C.the image of the dog is not created
D.the sensor fails to convert light and colour into a digital information
69.The main reason that sports photographers can get clear and big photos of players is thatD.
A.they use digital cameras                              
B.the lens of their cameras is excellent
C.their focus lenses are short                        
D.their focus lenses are long
70.Generally speaking,a digital camera's price isA.
A.closely related to the quality of the CCD
B.irrelevant to the quality of the CCD
C.closely related to the lens
D.irrelevant to the lens.
17.Are  morning people  born or made?In my case it was definitely made.In my early 20s,I rarely went to bed before midnight,and I would almost always get up late the next morning.
But after a while I couldn't ignore the high relationship between success and rising early.On those rare occasions where I did get up early,I noticed that my productivity was almost always higher.So I set out to become a habitual early riser.But whenever my alarm went off,my first thought was always to stop that noise and go back to sleep.Eventually some sleep research showed me that I was using the wrong strategy.
The most common wrong strategy is this:You assume that if you're going to get up earlier,you'd better go to bed earlier.It sounds very reasonable,but will usually fail.
There are two main schools(流派) of thought on sleep patterns.One is that you should go to bed and get up at the same time every day.The second school says you should go to bed when you're tired and get up when you naturally wake up.However,I have found both of them are wrong if you care about productivity.If you sleep at set hours,you'll sometimes go to bed when you aren't sleepy enough.You're wasting time lying in bed awake and not being asleep.
If your sleep is based on what your body tells you,you'll probably be sleeping more than you need.Also,your mornings may be less predictable if you're getting up at different times.
The solution for me has been to combine both methods.I go to bed when I'm sleepy and get up with an alarm clock at a fixed time.So I always get up at the same time (in my case 5am),but I go to bed at different times every night-sometimes at 9:30pm,and other times at midnight.Most of the time I go to bed between 10-11pm.
However,going to bed only when I'm sleepy,and getting up at a fixed time every morning is my way.If you want to become an early riser,you can try your own.

60.According to the passage,the underlined phrase refers toB.
A.people who stay up until the next morning.
B.people who get up early in the morning.
C.people who feel sleepy in the morning.
D.people whose productivity is the highest in the morning.
61.Why did the author want to become a habitual early riser?B
A.Because he/she wanted to form the habit of going to bed early and getting up early.
B.Because he/she had found that his/her productivity was higher when he/she got up
early.
C.Because he/she wanted to see which of the two main schools of thought on sleep
patterns was right.
D.Because he/she was told the high relationship between success and rising early.
62.The author experienced all the following EXCEPTD.
A.going to bed after midnight          
B.getting up early occasionally
C.pressing off the alarm to go on sleeping
D.asking scholars for advice on sleeping habits
63.The passage is mainly aboutA.
A.how to become an early riser         
B.how to have good sleep
C.wrong strategies for getting up early
D.main schools of thought on sleep patterns.
4.Is a mouse that can speak acceptable?How about a dog with human hands or feet?Scientists,the people with the know-how to make such things happen,are now thinking about whether such experiments are morally right or not.
    On Nov.10,Britain's Academy of Medical Sciences launched a study on the use of animals with human materials in scientific research.The work is expected to take at least a year,but its leaders hope it will lead to guidelines for scientists in Britain and around the world on how far they can go mixing human genes into animals in search of ways to fight human diseases.
"Do these constructs (构想) challenge our idea of what it is to be human?"asked Martin Bobrow,a professor of medical genetics at Cambridge University and chair of a 14-member group looking into the issue."It is important that we consider these questions now so that appropriate boundaries are recognized."
Using human material in animals is not new.Scientists have already created monkeys that have a human form of the Huntingdon's gene so they can study how the disease develops; and mice with livers (肝) made from human cells are being used to study the effects of new drugs.
However,scientists say the technology to put ever greater amounts of human genetic material into animals is spreading quickly around the world---raising the possibility that some scientists in some places may want to go further than is morally acceptable.
     Last year in Britain there was a lively debate over new laws allowing the creation of human-animal embryos (胚胎) for experiments.On one side of the debate were religious groups,who claimed that such science interferes with nature.Opposing them were scientists who pointed out that such experiments were vital to research cures for diseases.
The experts will publish reports after the end of the study,in which they will give definitions (定义) for animal embryos with human genes or cells,look at safety and animal welfare issues,and consider the right legal framework to work within.
72.What does the underlined word"they"in Paragraph 2 refer to?A
A.Scientists in Britain and around the world.
B.Leaders of the research.
C.Guidelines for scientists.
D.Scientific experiments.

A.test new drugs on animals 
B.to find ways to fight human diseases
C.prove the research is morally acceptable
D.create monkeys and mice with livers made from human cells

A.the experts will release reports after the study
B.scientists have never doubted the use of animals with human materials
C.the creation of human-animal embryos for experiments is legal in Britain
D.religious groups hold that cures for diseases have to be done through experiments
75.What would be the best title of the passage?A
A.Morally right or not?
B.A debate about new laws
C.Cures for diseases

19.Driving in New Zealand is not difficult but there are a few surprises.(36)D.The following hints should help you have a safe trip.
Driving is always kept on or below the legal speed limits indicated on road signs.The maximum speed on any open road is 100km/h.The maximum speed in urban areas is 50km/h.Adjust your speed as conditions demand.
(37)E.Although distances may seem short,New Zealand roads often include hilly,narrow or winding areas,which slow down your journey.If you're used to driving in the city,take care when driving on the open country roads,and watch out for single-lane bridges.
New Zealand accepts the national driving licenses of all other countries for tourists staying less than 12months.You must carry your license while driving.After a period of one year,you must apply for a New Zealand driver's license.(38)F.
Most open roads are a single lane each way,except for motorways coming into larger cities (Auckland,Wellington and Christchurch).Before overtaking,make sure you will have at least 100m of a clear road in front of you.Do not pass on double yellow lines-these indicate that it's too dangerous to overtake.
Road conditions are variable.Off the main highways some roads may be not opened and extra care needs to be taken.(39)C Ask your rental car company to mark these roads on your map before setting off.
In winter some roads may be dangerous due to ice or snow,particularly around mountain passes.(40)B Do not brake suddenly on ice.In some cases chains may be required (rental cars usually come with chains supplied).Make sure you're familiar with how to fit them.
A.If you have an international driving permit,you can drive for one year after you
first arrive in New Zealand.
B.Look out for signs indicating slippery surfaces and drive slowly.
C.A few of them are not safe for vehicles and insurance does not cover them.
D.You should be aware of our road rules and driving restrictions before you set out.
E.Don't underestimate driving time.
F.You will have to pass a theory test,and a practical test.
G.Check rental agreements before hiring a car to drive.
