分析 --他們多久才能印刷完報(bào)紙？
--大約五小時(shí)之后．

點(diǎn)評(píng) 疑問(wèn)詞組通常用來(lái)構(gòu)成疑問(wèn)句，要根據(jù)回答的具體內(nèi)容進(jìn)行選擇，注意一些固定搭配，分清疑問(wèn)詞的用法．

10．I recently spent two years in the Arctic（北極）filming the series（連續(xù)�。〣lue Planet．I love being in an environment that hasn't changed for 20，000years．Of course it's freezing，but it must be a healthy place because you never catch a cold．
When I am filming，I like to really feel how lonely the environment is．Filming underwater involves cutting through thick ice．When diving in，you should tie to a line．The person at the other end of the line has to pull you out fast if necessary．
At first I was a research diver for the British Antarctic Survey Project，but for me，science isn't exciting enough．I'd always enjoy photography，and whenever camera teams passed through，they encouraged me to watch and learn．I was then able to move into filming in 1985and have concentrated on Arctic and Antarctic wildlife ever since．
I prefer to be face to face with the animals I'm filming．I haven't been in the water with killer whales yet，but I plan to．Of course，it's dangerous if you choose the wrong moment．．They're big animals and can move fast，so I'd be stupid to film them when they are searching for food!
I have never had problems with polar bears，although once I was frightened when one tried to get into my tent．Polar bears are bold，clever and dangerous．But I made the bear understand I wouldn't hurt it．
Now I come back home，I work in the mornings and spend the afternoons swimming to keep fit．Now I'm fifty，and filming is harder．The challenge（挑戰(zhàn)）for me is to go on with the high-quality work．

74．The writer loved the Arctic becauseC．
A．it's freezing
B．it's changeable
C．it's a healthy place
D．it's an exciting place
75．From the third paragraph we know that at first the writer was aA．
A．research diver
B．scientist
C．a(chǎn) photographer
D．film-maker
76．The underlined phrase"the wrong moment"refers to the time when the whales areA．
A．hungry
B．meeting strangers
C．having a rest
D．moving fast
77．Talking about his experience with a polar bear，the writer saidC．
A．the animal was much more afraid than he was
B．he felt excited，having no idea that the bear might attack him
C．the bear seemed to know that he wasn't dangerous
D．he realized he was wrong to trust polar bears
78．What does the writer think of his job as a cameraman now？D
A．It's dangerous．
B．It's boring．
C．It's for young people．
D．It's difficult．
79．The passage is mainly aboutB．
A．the good chances in TV camera work
B．the challenges of the environment the writer works in
C．the difficulties of having to work alone
D．the beautiful scenery of the Arctic．

11．The crab is a living clock．It tells the time of the day by the colour of its skin，which is dark by day and pale by night．The crab's changing skin colour is a regular twenty-four hour cycle（周期）that follows the daily rhythm（循環(huán)）of the sun．
    Does the crab really keep time，or is its skin simply affected by the sun's rays（光線），changing colour with the amount of the sunlight？To find out the answer，scientists kept some crabs in a dark room for two months．Even without daylight the crabs'skin colour continued to change．
    The change probably had something with the rhythm of the sun，to help protect the crab from the sunlight and enemies．After millions of years it has become completely regular inside the living body of the crab．
    Scientists noticed that once each day the colour of the crab is especially dark，and that each day this appears about fifty minutes later than the day before．From this they discovered that each crab follows not only the rhythm of the sun but also that of the tides（潮汐）．The crab's darkest period（一段時(shí)間）is the time of low tide on the beach where it is caught．
33．The crab's changing colourB．
A．tells the crab what time it is               
B．protects the crab from the sunlight
C．keeps the crab warm                     
D．gives the crab a lot of energy
34．Scientists studied crabs in order to find outC．
A．why they change colour                   
B．how to use them as clocks

D．where they can be caught
35．When the crabs were kept in the dark，D．
A．they didn't change colour                   
B．they changed colour more quickly
C．they changed colour more slowly             
D．they changed colour as usual

A．in a regular 24-hour rhythm           
B．a(chǎn)t low tide
C．with the sun's rays
