12．Before space travel，an astronaut must know        it might feel like to stay in an imaginary environment．（　�。�
A．whenB．whatC．howD．that

分析 天空旅行之前，宇航員必須知道這一個虛幻的環(huán)境里感覺會是什么樣的．

解答 答案：B
題干中it might feel like to stay in an imaginary environment是作動詞know的賓語，是一個賓語從句；從句中feel like缺少賓語，要用連接代詞．故選B．

點評 從屬連詞是連詞的一種，用來引導(dǎo)名詞性從句和狀語從句．大致可分為三大類：that（無詞義，不做成分）if，whether （表達(dá)是否的意義，但不做句子成分）； 連接代詞：who，whom，whose，what，which，whatever，whoever，whichever（有詞義，在句子中可作主語、表語、賓語）；連接副詞：when，where，why，how，how many，how long，how far，however，whenever，wherever （有詞義，作從句的狀語）．學(xué)習(xí)時，要注意區(qū)分和掌握．

4．All people need to sleep．Sleep is a restorative （恢復(fù)體力的） process that promotes proper body functioning and can improve the quality of your life．Not only is the quantity of sleep important，but also the quality of sleep．
Your bedroom should be shaped to your taste and to allow you to sleep in a peaceful environment．One of the biggest mistakes people make in their sleep is to use their bedroom for activities other than sleep．If your bedroom also functions as a command station for your life and work，the likelihood of your sleeping being poor is rather high．Bedrooms should be designed，decorated and used for sleep mainly．TVs，computers and other things should not be in your bedroom at all if possible．
Establishing regular sleeping and waking times can help improve the quality of your sleep especially for those suffering from sleeplessness．Avoid hot food，caffeine，sugar and alcohol at least 4to 6hours before your sleep time．Develop a regular exercise program．Proper exercise and nutrition will help improve sleeping patterns．However，avoid exercising 2hours before sleeping，since this may stimulate your body and make sleeping more difficult．
Establish a pre-bedtime rule that will help focus you on sleep．You can try meditation（沉思），reading or deep breathing and relaxation．Your bedtime rule should be yours．Do not worry about it fitting into a specific category．Do what is the best for you．
Things such as room temperature，noise and light levels and even your bed mattress can have a lot of effect on the quality of sleep that you experience．Block out distracting noises and lights．You are in your bedroom to sleep and not be distracted by environmental interferences（干擾）．

28．It can be inferred from the passage thatC．
A．bedrooms should be used for more activities
B．TVs and computers in bedrooms can help people sleep faster．
C．the bedroom should be a place where you can sleep peacefully
D．your life and work result in your poor sleep
29．If you have difficulty sleeping，D．
A．hot food，caffeine，sugar and alcohol are good for you．
B．you need proper exercise just before sleeping
C．a(chǎn) pre-bedtime rule fitting into a given category is a must
D．you'd better keep regular hours

C．How to decorate your bedroom．

17．What is the single largest cause of sick leave in the UK？The answer is not the common cold or flu，but back pain．Back pain affects one in three British adults，costs the country over 5billion pounds every year and is very difficult to treat．But now Britain's National Health Service（NHS）will be offering a new solution：acupuncture．The ancient Chinese needle therapy（療法）has been around in the UK for many years，but this is the first time it has been officially approved by the NHS's advisory body，the National Institute for Clinical Excellence（NICE）．
Traditionally，doctors in the UK have advised back pain sufferers to stay active，do stretching exercises and take painkillers when necessary and in more serious cases some people are given X-ray treatment or injections with therapeutic substances．
NICE，however，say there is evidence that acupuncture may be more effective than expensive X-rays or injections，so patients who have been suffering for over six weeks should be given a choice．As an alternative to acupuncture，patients will be able to choose for either a course of spinal manipulation（脊柱推拿術(shù)），or a series of special exercise sessions．In the UK，acupuncture is classed as a complementary therapy，which is the term given to a medical procedure which hasn't received the strict trials by which scientists prove some treatments work．
While many experts have welcomed the move to make acupuncture available on the NHS，some are still doubtful about its effectiveness．Research from the US earlier this month found that using toothpicks could be as good as using real needles．So while some are yet to be convinced，back pain sufferers will be hoping that acupuncture helps get them feeling healthy and mobile again．Employers，on the other hand，will be hoping it gets them back to work．

32．What can we learn from the first paragraph？B
A．The British have come to know acupuncture recently．
B．About thirty percent of the British suffer from back pain．
C．NICE has been arguing against Chinese needle therapy．
D．The British ask for sick leave mostly because of cold or flu．
33．The traditional ways to treat back pain in the UK includeC．
A．staying in bed for rest    
B．Chinese needle therapy
C．receiving X-ray treatment 
D．a(chǎn)voiding physical exercises
34．In treating back pain，acupunctureA．
A．may cost less than X-rays    
B．works surely better than injections
C．has gone through strict scientific tests 
D．will replace the traditional ways in the UK
35．What do experts think of acupuncture？D
A．They think highly of it．    
B．Most of them are against it．
C．Few recognize its usefulness．
D．They differ on its effectiveness．

4．Professor Wiseman expects thousands of people to take part in an experiment in controlling dreams．
Participants will download a specially designed iphone app that turns their phone into a dream factory．Placed on the bed，the phone can monitor when a sleeper is not moving，which suggests the onsetof dreaming．It then plays a carefully crafted（精心制作的）"soundscape"designed to produce pleasant scenes such as walking in the woods，or lying on a beach．The idea is that this will influence dreaming，causing dreamers to form fantasyland inspired by the sounds they are hearing．At the end of the dream the app sounds a gentle alarm to wake the dreamer，who submits a brief description of the dream to a"dream catcher"database（數(shù)據(jù)庫）．
Prof Wiseman，from the University of Hertfordshire，who is best known for his research on sleeps，said，"Getting a good night's sleep and having pleasant dreams promotes people's productivity，and is necessary for their mental and physical well being． Despite this we know very little about how to influence dreams．This experiment aims to change that．"
As many as 10，000 people are expected to take part in the study，declared at the Edinburgh International Science Festival．Prof Wiseman teamed up with app developers YUZA，which created the"Dream：ON"software．Participants will be encouraged to share their dreams via Facebook and Twitter．
A national survey conducted for the experiment found that 21% of people had trouble sleeping and 15%suffered from unpleasant dreams．Prof Wiseman said people feeling low dreamed far more than others，and often had negative dreams．"Perhaps improving their dreams might help them，"he added．
The"Dream：ON"app can be downloaded for free from iTunes or via the project site，http://dreamonapp．com．
64．What is the special function of the"Dream：ON"software？B
A．Recording the process of dreams．    B．Sweetening dreams．
C．Stopping unpleasant dreams．         D．Waking up dreamers．
65．Why does professor Wiseman carry out the experiment？D
A．To improve the quality of sleeping．
B．To analyse mental effect on dreamers．
C．To set up a worldwide dream database．
D．To know about how to affect dreams．
66．If you volunteer to participate in the study，you are expected toC．
A．pay to download the"Dream：ON"app
B．lie on a beach with your smartphone on
C．present your dreams via Facebook and Twitter
D．design a pleasant situation according to the sound
67．The word"onset"in the 2nd paragraph probably meansC．
