3．Everyone knows that death is natural，but do you have any idea of the process of dying？Modern scientists divide the process of dying into two phases---clinical or temporary death and biological death．Clinical death occurs when the vital organs，such as the heart or lungs，have ceased to function，but have not suffered permanent damage．The organism can still be revived（复活）．Biological death occurs when changes in the organism lead to the"breaking up"of vital cells and tissues．Death is then unchangeable and final．
Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs．The best method developed so far involves cooling of the organism，combined with narcotic sleep．By slowing down the body's metabolism（新陈代谢），cooling delays the processes leading to biological death．
To illustrate how this works，scientists performed an experiment on a six-year-old female monkey called Keta．The scientist put Keta to sleep with a narcotic．Then they surrounded her body with ice-bags and began checking her body temperature．When it had dropped to 28 degrees the scientists began draining blood from an artery．The monkey's blood pressure decreased and an hour later both the heart and breathing stopped：clinical death set in．For twenty minutes Keta remained in this state．Her temperature dropped to 22 degrees．At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing．After two minutes Keta's heart became active once more．After fifteen minutes，spontaneous（自发的）breathing began，and after four hours Keta opened her eyes and lifted her head．After six hours，when the scientists tried to give her a penicillin injection，Keta seize d the syringe and ran with it around the room．Her behavior differed little from that of a healthy animal．
32．For a person who suffers from the clinical deathD
A．he is still very much alive．
B．he can not avoid final death．
C．his most important organs are damaged．
D．he still has the possibility of getting back to life．
33．Scientists try to make the time of clinical death longer in order toB
A．cool the organism．
B．delay the coming of biological death．
C．slow down the body's metabolism．
D．bring vital cells and tissues back to active life．
34．How did the scientists put Keta into clinical death？A
A．By putting her to sleep，lowering her temperature and draining her blood．
B．By surrounding her body with ice-bags and draining her blood．
C．By lowing her blood pressure and stopping her heart from beating．
D．By draining her blood，lowering her blood pressure and stopping her breathing．
35．All of the following indicate that the monkey has almost restored to her original physical state except the fact thatB
A．her heart beat again．
B．she rejected a penicillin injection．
C．she regained her normal breath．
D．she acted as lively as a healthy monkey．

4．See a cellphone cover that you like on Taobao？Forget about placing an order，paying the bill online and waiting for days for it to be delivered to you．In the near future，you'll be able to get it in minutes just by hitting"print"on your computer．
　 You might find it hard to believe that you could actually"print"an object like you would a picture．But it is not that hard to understand how it would work．Just as a traditional printer sprays （喷） ink onto paper line by line，modern 3D printers spread material onto a surface layer by layer，from the bottom to the top，gradually building up a shape．
　 Instead of ink，the materials the 3D printer uses are mainly plastic，resin（树脂） and certain metals．The thinner each layer is-from a millimetre to less than the width of a hair-the smoother and finer the object will be．
　 This may sound like a completely new technology，but the truth is that 3D printing has been around since the late 1980s．Back then，it was barely affordable for most people，so few knew about it．
    Last year，though，saw a big change in the 3D printing industry-printers became much cheaper．For example，10 years ago a desktop 3D printer might have cost￡20，000，while now they cost only about￡1，000，accordin g to the BBC．
    Taken out of the factory and introduced to more diverse and common uses，3D printing can create just about anything you can think of-flutes （笛子），bikinis，jewelry，aircraft parts and even human organs．In fact，scientists from Cornell University in New York have just made an artificial ear using a 3D printer，according to Science Daily．The fake ear looks and acts exactly like a natural one．
    However，as 3D printing becomes more common，it may bring about certain problems-such as piracy．"Once you can download a coffee maker，or print out a new set of kitchen utensils （餐具） on your personal 3D printer，who will visit a retail （零售的） store again？"an expert in 3D printing told Forbes News．Even more frightening，what if anyone in the world could use a 3D printer to print out a fully functioning gun？
32．According to the article，in the future，the 3D printing technology willB．
A．enable people to make better purchases online
B．change the way we make many products
C．be applied as widely in our daily life as computers
D．shorten the time it takes for people to get what they buy online
33．What happened in the 3D printing industry last year？D
A．The 3D printing technology was taken out of the factory．
B．The 3D printing technology began to be used in various fields．
C．The 3D printer was used for medical treatment for the first time．
D．The 3D printer became more afforda ble for consumers．
34．How is the last paragraph developed？A
A．By giving examples．
B．By making comparisons．
C．By analyzing the cause and effect．
D．By presenting research findings．
35．What is the best title of the passage？D
A．Great Demand for 3D Printers

1．近期，雾霾天气频频发生，空气质量越来越差，环境保护越来越受到人们的关注．
作为一名青少年，我们如何尽自己的微薄之力来保护环境，请提出你自己的几点建议．
要点：
1．环境的现状；2．环保受到人们的更多关注；3．应采取的措施．
注意：词数100-120（开头不计入总词数）．
Recently，the Dust-haze weather hit China over and over again．

2．When I brush my teeth each morning，I see my tongue，and feel slightly amazed that it's going to be insured（投保） for￡1 million．I had never really paid much attention to it until I became a baby-food tester．Now，my tongue---or rather，its ability to determine tiny changes in flavor---is the primary tool of my job．The company I work for believes I'm so valuable in terms of getting the balance of tastes in baby food just right that it's worth getting insured．
I'm what you call a"supertaster"---one of a small percentage of the population born with twice as many taste buds（味蕾） as the rest．Babies are typically born with more than 10，000taste buds，but in later life they decrease to as few as 5，000．At 24I should really be at the height of my tasting power．
At first，baby food tasted strange to me---it took a while to get used to eating a meal that had been reduced to a paste（糨糊）．Also，I have to make a real effort to think like a baby---to imagine that each time I put a spoonful of pie in my mouth，I am six months old again．I still avoid tasting baby fish pie after breakfast．
I am more aware of the need to protect my tongue these days，particularly before a tasting session，and to avoid any strong tastes or smells，such as coffee and perfume．I also drink plenty of water during the day to clean my palate（味觉）．
It's not really something that affects my personal life．Outside work it's a joy to be able to taste everything so deeply．One consequence is that eating is a much richer experience for me than for most people．If I take one bite of a salad，I can tell immediately what's in the dressing．I like the challenge of guessing what's in anything I eat，and the satisfaction of rarely getting it wrong．

24．The reason why the author is being insured is thatA．
A．few people have his tasting power
B．he manages valuable assets for his company
C．baby-food testers'taste buds are easily injured
D．he makes well-balanced meals for babies
25．The author is a good baby-food tester because heB．
A．is good at making baby food
B．has more taste buds
C．knows a lot about nutrition
D．is young
26．How does the author protect his tongue？D
①By avoiding strong tastes．
②By brushing his teeth every day．
③By staying away from strong smells．
④By drinking plenty of water．
A．①②③
B．②③④
C．①②④
D．①③④
27．What does the author mean by saying that"eating is a much richer experience for me than for most people"？C
A．He can learn a lot about food by tasting it．
B．He can easily tell which of two foods is better．
C．He is more sensitive to flavor than other people．
D．He spends much of his time eating every day．
