12.There is an island called Kitava,way out there in the Pacific Ocean,in the Milne Bay Province of Papua New Guinea.It is one of the four main Trobriand Islands with a total population of 12,000 native residents.Rich with culture,surrounded on all sides by clear blue water and abundant rainforest,Kitava is as apealing as it is remote.But it has more to offer than good views.
As Byrdie reports,Kitava is also home to a people whose diet and nutritional habits remain healthy,untouched by Western influence.A lifetime of not knowing the sweet,sweet sensation of the salt from a potato chip hitting the roof of your mouth has done more than just spare Kitavans from illnesses like diabetes and cardiovascular disease; it's also given them a lifetime of smooth,acne(痤疮)-free skin.
In a study of l',200 subjects-including 300 teens and young adults-conducted by a team led by medical doctor and professor Steffan Lindeberg over 843 days,not one breakout was reported.They also found that genetics played little to no role in the results.
In fact,the average Kitavan diet is fairly common.It's simple,with no"miracle fruit"or"rare nut"to speak of,and Kitavans don't even exercise much.That diet consists mainly of yams( 山荮),sweet potatoes,and taro (芋头),local fruits (namely coconut),fish,and vegetables.
But if you're already pulling out your suitcases and drafting a resignation letter to your boss,you might want to slow your step.For one thing,the closest airport is over 700 miles away from the island,so good luck getting there.And consider this:do you really want to move somewhere where you'll be the only person with acne until the diet kicks in?I don't think so.

28.Which are the contributing factors of attracting visitors to the island?B
a.Rich culture.b.Clean white sand     c.Thick rainforest   
d.Clear blue water  e.Romote tribes
A.abc       B.acd         C.bcd        D.ade
29.What accounts for the fact that the Kitavans own good skin?D
A.They don't like eating salt..
B.They enjoy varieties of rare fruits.
C.They are sick of exercising..
D.They follow simple but healthy diet.
30.What is unlikely to be included in the Kitavans'diet?C.
A.Taro            B.Fish              C.Potato chips        D.Coconut
31.What can we learn from the last paragraph?A
A.Think twice before moving to Kitava.
B.Don't hesitate to quit your job and move there.
C.One can reach Kitava by plane without difficulty.
D.Anyone will own acne-free skin on stepping on Kitava.

10.One night last February,a seventeen-year-old Duffy drove home along a winding road,he saw a strange light thrown against the tree."I knew it wasn't the moon",he said."I drive this road all  (61)thetime and I notice little things out of place."
Duffy stopped his car and got out(62)to examine (examine).Below him far down in the deep valley lay a broken car with its headlights on.Thirty minutes earlier,a man had driven off the edge of the road,which has no guardrail(护栏).His car fell and rolled end over end,(63)landing(land) on its top more than two hundred feet below.
Duffy rushed to call for help,then returned and got down to reach the driver(64)who/that   was badly injured.Snow covered the valley(65)and  the temperature was below freezing.After struggling back up the cliff,Duffy took off his jacket and shirt and wrapped the man in time,along(66)with the blankets from his car.
Life-saving  (67)deeds(deed) are starting to become usual action for Duffy,the oldest of seven children.When he was 12,he saved his ten-year-old brother from drowning.Two years ago,his three-year-old sister (68)ate(eat)rat poison,and Duffy(69)instantly (instant)cleaned out her mouth,make her drink milk to protect her stomach and called doctors.
"We personal belief is that it is(70)significant(significance)for us to teach the children good values,and it looks like we have got some reward for it."His father says.
9.What's more exciting than having a fresh hot pizza delivered to your door?How about having it brought to you by a robot?Thanks to Domino's Robotic Unit or DRU,that just became a reality!On March 8,the three-feet tall robot delivered its first pizza to some lucky residents in Brisbane,Australia.
The fully autonomous DRU is the result of a cooperation between Domino's Pizza Australia and Sydney based startup Marathon Robotics.The 450-pound machine that travels at a maximum speed of 12.4miles an hour can cross a distance of up to 12miles and back,before requiring a battery recharge.LIDAR,a laser-based sensor technology similar to the one used in self-driving cars,enables DRU to detect and avoid obstacles,while traditional sensors,much like those used in vacuum robots ensure its path is safe as it heads to its destination.
The robot can fit up to ten pizzas and even has a separate cold area to accommodate drink orders.
Equipped with both Google Maps and GPS guidance,DRU can navigate bike paths and sidewalks and also find the most efficient way to its destination.Since the robot does not have to deal with road traffic,it could potentially make deliveries a lot quicker than humans.To access their food,customers have to enter the unique code provided to them by the company.This not only ensures that they pick up the right pizza,but also prevents the pies from getting stolen en route.
Though Domino's has thus far built just a single prototype(样机),they expect additional DRU to be ready for service in their various Queensland locations within the next six months.But don't expect these super cute robots to replace humans anytime soon.According to Domino's the DRU still needs extensive testing,which the company believes could take up to two years.
And then there is also the problem of regulations.The public use of autonomous vehicles is still banned in most countries.But Don Meij,the CEO and Managing Director of Domino's Pizza Australia New Zealand Ltd,is not worried.One day DRU will become an integral part of the Domino's family."We for one cannot wait!

28.The first paragraph is mainly used toC.
A.comment              B.praise          C.introduce         D.conclude
29.How can DRU detect and avoid obstacles?B
A.By navigating bike paths and sidewalks
B.By using a laser-based sensor technology
C.By being equipped with both Google Maps and GPS-guidance
D.By using traditional sensors,much like those used in vacuum robots
30.What must a customer do to get the food delivered by DRU?D
A.He/She should press their finger on a fingerprint scanner
B.He/She should let the robot recognize his/her face
C.He/She should scan the QR (quick response) code on the robot
D.He/She should enter a cod supplied by the company
31.What can we know from the last two paragraphsA
A.The DRU requires to be tested further
B.Domino's has built a few kinds of such a robot
C.Don Meij is the CEO of Sydney based startup Marathon Robotics
D.The public use of autonomous vehicles is allowed in most parts of Australia.

7.Like many other people,I love my smart phone,which keeps me connected with the larger world that can go anywhere with me.I also love my laptop,because it holds all of my writing and thoughts.In spite of this love of technology,I know that there are times when I need to move away from these devices and truly communicate with others.
On occasion,I teach a course called History Matters for a group of higher education managers.My goals for the class include a full discussion of historical themes and ideas.Because I want students to thoroughly study the materials and exchange their ideas with each other in the classroom,I have a rule-no laptop,iPads,phones,etc.When students were told my rule in advance of the class,some of them were not happy.
Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology.There's a bit of truth to that.Some students assume that I am anti-technology.There's no truth in that at all.I love technology and try to keep up with it,so I can relate to my students.
The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly engage complex ideas.Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas.I want students to dig deep within themselves for inspiration and ideas.I want them to push each other to think differently and make connections between the course materials and the class discussion.
I've been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create.Students realize that with deep conversation and challenge,they learn at a level that helps them keep the course materials beyond the classroom.
I'm not saying that I won't ever change my mind about technology use in my history class,but until I hear a really good reason for the change,I'm sticking to my plan.A few hours of technology-free dialogue is just too sweet to give up.

56.Some of the students in the history class were unhappy withB.
A.the course materials
B.the author's class regulations
C.discussion topics
D.others'misuse of technology
57.Which of the following statements is true?D
A.The author made the rule in that he was against technology.
B.The author made the rule mainly because of his unpleasant experiences.
C.The author's history class received low assessment.
D.The students think highly of the author's history class.
58.According to the author,the use of technology in the classroom mayD.
A.allow students to get on well with each other
B.improve teaching and offer more help
C.help students to better understand complex themes
D.prohibit students being involved in class
59.What can we infer from the passage?A
A.The author will carry on the success in the future.
B.Some students will be punished according to the rule.
C.More and more students will be absent in history class.
D.The author will help students concentrate on what they learn.
6.How Safe Is Your Bed?
Do you consider your bed a safe place of rest and calm?Do you sink into a mattress (床垫) after a hard day's work and feel tension and stress drain away as you rest your weary head on a soft pillow?Well,you might not feel so relaxed if you knew that tiny pests were hiding there!It seems that beds may not be such a good place for our health and happiness----they could actually be making us ill!
Recent studies have shown that bacteria,fungi and dust mites (螨虫),some smaller than the diameter of a hair,live in our bedding.When we move around in our sleep,we disturb them and they are bounced up into the air--which we then breathe in as we sleep.According to the American Lung Association,four out of five households in the United States now have high levels of dust mites,although it's not the mites themselves that cause the problems,but their droppings.These are"highly allergenic (致敏的)"according to Dr William Berger,a fellow with the American Academy of Allergy,Asthma and Immunology."Even if you aren't allergic…they can still irritate you,the way pepper would if it blew into your nose and eyes."
Brendan Boor,Assistant Professor of Civil Engineering,who carries out bed research,also found that bed dust in the air leads to allergies--causing watery eyes,sneezing,coughs and asthma.He has recommended ways to limit our exposure to these boring allergens:
Firstly,he suggests vacuuming your mattress regularly-weekly,or even daily.He also recommends doing away with carpets and washing floors.Using allergen-proof bed covers,he says,can reduce the risk of getting allergies.In addition,washing bedding and pillows frequently can help,as can a portable air cleaner placed near the bed.
If you do as Brendan Boor suggests,you will breathe in cleaner air as you sleep …or will you?Is it really safe for you to go back in your bed?
Studies show that beds aren't a good place for your well-being and they can even make you sick.Mites,bacteria and other tiny living things in your beds can cause illness or irritate you.Therefore,experts suggest that cleaning carpets,washing floors,using allergen-proof bed covers,and washing bedding and pillows frequently can make your bed safe..
5.Culture can affect not just language and customs,but also how people experience the world on surprisingly basic levels.
Researchers,with the help of brain scans,have uncovered shocking differences in perception (感知) between Westerners and Asians,what they see when they look at a city street,for example,or even how they perceive a simple line in a square,according to findings published in a leading science journal.
In western countries,culture makes people think of themselves as highly independent entities (实体).When looking at scenes,Westerners tend to focus more on central objects than on their surroundings.East Asian cultures,however,emphasize inter-dependence.When Easterners look at a scene,they tend to focus on surroundings as well as the object.
Using an experiment involving two tasks,Dr Hedden asked subjects to look at a line simply to estimate its length,a task that is played to American strengths.In another,they estimated the line's length relative to the size of a square,an easier task for the Asians.
The level of brain activity,by tracking blood flow,was then measured by Brain Scanners.The experiment found that although there was no difference in performance,and the tasks were very easy,the levels of activity in the subjects'brains were different.For the Americans,areas linked to attention lit up more,when they worked on the task they tended to find more difficult--estimating the line's size relative to the square.For the Asians,the attention areas lit up more during the harder task also--estimating the line's length without comparing it to the square.The findings are a reflection of more than ten years of previous experimental research into east-west differences.
In one study,for instance,researchers offered people a choice among five pens; four red and one green.Easterners were more likely to choose a red pen while Westerners were more likely to choose the green one.
Culture is not affecting how you see the world,but how you choose to understand and internalize (使内化) it.But such habits can be changed.Some psychological studies suggest that when an Easterner goes to the West or vice versa,habits of thought and perception also begin to change.Such research gives us clues on how our brain works and is hopeful for us to develop programs to improve our memory,memory techniques and enhance and accelerate our learning skills.
