19.Mosquitoes have an extraordinary ability to target humans far away and fly straight to their unprotected skin.Regrettably,mosquitoes can do more than cause an itchy(发痒的)wound.Some mosquitoes spread several serious diseases,including Dengue,yellow fever and malaria.
Over one million people worldwide die from these diseases each year.New research now   shows how mosquitoes choose who to bite.
Mosquitoes need blood to survive.They are attracted to human skin and breath.They smell the carbon dioxide gas,which all mammals breathe out.This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.
But mosquitoes also use their eyes and sense of touch.Michael Dickinson is a professor at the California Institute of Technology.His research shows how these small insects,with even smaller brains,use three senses to find a blood meal.
Michael Dickinson's team used plumes-a material that rises into the air of carbon dioxide gas into a wind tunnel.They then used cameras to record the mosquitoes.The insects followed the plume.
Then,the scientists placed dark objects on the lighter colored floor and walls of the tunnel.Mr.Dickinson said,at first,the mosquitoes showed no interest in the objects at all."What was quite striking and quite surprising is that the mosquitoes fly back and forth for hours.These are hungry females and they completely ignore the objects on the floor and wall of the tunnel.But the moment they get a hit of CO2,they change their behavior quite obviously and now would become attracted to these little visual blobs (斑点)."
This suggested to the researchers that a mosquito's sense of smell is more important in the search for food.Once mosquitoes catch a smell of a human or animal,they also follow visual signals.
12.What do mosquitoes mainly use to find their targets?A
A.Sense of smell              
B.Sense of touch
C.Sense of sight              
D.Smart brains
13.The first response of the mosquitoes to the objects in the experiment isC.
A.to fly to the dark ones         
B.to cat ch and stick to them
C.to take no notice of them       
D.to attach themselves to them
14.How can we avoid being attacked by mosquitoes according to the text?D
A.Don't let them see us.
B.Use dark objects to stop them.
C.Make them fly back and forth for hours.
D.Attract them to objects full of carbon dioxide gas.
15.What can be the best title for the text?C
A.How Do Mosquitoes Survive?
B.Why Do Mosquitoes Need Blood?
C.How Do Mosquitoes Choose to Bite You?
D.Why Do Mosquitoes Attack the Human Being?

分析 本文解释了蚊子叮人的依据,通过实验发现蚊子是依靠二氧化碳来追踪叮咬目标.

解答 12.A细节理解题.根据句子This gas is the main way for mosquitoes to know that a warm-blooded creature is nearby.可以得出蚊子依靠嗅觉叮人,所以选A.
13.C 细节理解题. Mr.Dickinson said,at first,the mosquitoes showed no interest in the objects at all.狄金森先生说,起初,蚊子对对象根本不感兴趣.stick to 粘着;take no notice of 不注意;attach ones to依附着.所以答案为C.
14.D 推理判断题.But the moment they get a hit of CO2,they change their behavior quite obviously and now would become attracted to these little visual blobs 但是,当他们受到二氧化碳的影响,他们改变他们的行为非常明显,现在会吸引这些小视觉斑点.可以推断出蚊子对二氧化碳敏感可以用二氧化碳诱骗蚊子,所以答案 选D.
15.C主旨大意题.New research now   shows how mosquitoes choose who to bite.新的研究表明蚊子是如何选择咬人的.得出本文的主旨,所以答案选C.

10.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 5 billion 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(疗法)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-ra y 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(脊柱推拿术),or a series of special exerci se 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.avoiding 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.
14.A year ago,my son Michael,who had just graduated from high school,had to choose between two summer jobs.He could work either at my basketball camp(61)orat one of the horse farms in the Lexington,Kentucky,area.It was his choice.He(62)chose (choose) the horse farm,because he was tired of working my camps,and he thought he could make more money at the horse farm.But(63)afteronly a few days he realized he hated it.Farm work is hard,and he was spending most of his time(64)walking (walk)horses on a treadmill and shoveling manure.One day a couple of weeks into the summer he came to me and said he'd made a mistake and(65)would rather work at my basketball camp.
   I understood,but I told him that he'd made a commitment and now he was going to have to follow through with it,no matter(66)howunpleasant.Quitting was not an option.
   Sometimes,of course,we fail to accomplish our goals.But we have to remember that failure is a part of life and failure is only fertilizer for future success.I've often heard people say that failure teaches us(67)nothing.I don't believe it.There are so many lessons we can learn(68)from failure.Most of all,we learn what (69)notto do.It's like the child who touches the hot stove,and then keeps doing it.The first time is part of the learning process.The second time it's stupid.
     The only time failure is truly bad is if you use it(70)as an excuse to quit.
4.Will it matter if you don't take your breakfast?Recently a test was given in the United States.Those tested included people of different ages,from 12 to 83.During the experiment,these people were given all kinds of breakfasts,and sometimes they got no breakfast at all.Special tests were set up to see how well their bodies worked when they had eaten a certain kind of breakfast.The results showed that if a person eats a proper breakfast,he or she will work with better effect than if he or she has no breakfast.This fact appears to be especially true if a person works with his brains.If a student eats fruit,eggs,bread and milk before going to school,he will learn more quickly and listen with more attention in class.Contrary to what many people believe,if you don't eat breakfast,you will not lose weight.This is because people become so hungry at noon that they eat too much for lunch,and end up gaining some weight instead of losing some.You will probably lose more weight if you reduce your other meals.
21.During the test,those who were tested were givenD.
A.no breakfast at all              
B.a very rich breakfast
C.little food for breakfast        
D.different breakfasts or none

23. The passage infers that many people believe that if you don't eat breakfast,you willA.
A.lose weight              
B.not lose or gain weight
C.be healthier              
D.gain a lot of weight

C.Having a big lunch and supper is of great value in weight-losing.
