    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．

    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．

    The Indian elephants from a temple are sent on a north-long holiday with massages（按摩） and baths to relax．The 64elephants will be fed with a lot of food，enough for them to put on 700～800pounds．
    A temple veterinarian said that those Indian elephants would be treated after spending a month walking on roads，living on leaves and bananas and giving shows during lots of temple festivals．Their daily diet includes special rice and other special food，which are very nutritious and can make them healthy and strong．All of these are made by professional people．
