Snowblind--it's a frightening word.Thankfully,it's a condition that is totally preventable.
Snow blindness is a painful,temporary loss of vision due to overexposure to the sun's UV rays.Essentially,snow blindness is caused by a sunburned eye.
(36)AThough it is commonly called snow blindness,the condition can (and often does) occur in the absence of snow.
The terms"snowblind"and"snow blindness"have become popular because snow is highly reflective of ultraviolet radiation.(37)E Also,skiing,mountain climbing and snowboarding usually take place at relatively high altitudes,where the sun's UV rays are stronger.Combined,these factors can double your risk of getting sunburned eyes,compared with being outdoors at lower altitudes in the summertime.
(38)GTelevision journalist Anderson Cooper experienced snow-free snow blindness first-hand a few years ago when he spent a couple hours on a boat in Portugal without sunglasses and ended up"blind for 36hours,"according to his report of the incident.
Not only can you become snowblind without snow--it can happen without sunlight,too!(39)DFor example,sun lamps can cause temporary"snow"blindness if proper eye protection is not used.
(40)FTo relieve pain or discomfort from snow blindness,stay indoors and wear sunglasses.Keep your eyes well-moistened with artificial tears.For additional relief,use over-the-counter pain relievers.Be sure to use only pain relievers you know you can take without worry of an allergic reaction.You also may find that placing a cool,dampened washcloth over your closed eyelids is comforting.

A.You don't need snow to become snowblind.
B.It will likely affect those traveling in snowy conditions.
C.To prevent snow blindness on the slopes,wear sunglasses.
D.Sometimes it occurs from man-made sources of ultraviolet radiation
E..In fact,snow can reflect over 80percent of the UV rays that fall upon it.
F.Snow blindness is scary,but usually it's temporary,and there are ways to relieve the discomfort.
G.But water and white sand also are highly reflective of the sun's UV rays,thus increasing the risk.

分析 "雪盲"是一种很可怕的现象,在没有雪的情况下也会发生,文章介绍了几种可以预防"雪盲"发生的方法.

解答 AEGDF
36.A 细节题.根据后面的句子Though it is commonly called snow blindness,the condition can (and often does) occur in the absence of snow.可知,虽然该词普遍被叫做"雪盲",但是在没有雪的地方也会发生,故选A.
37.E 细节题.根据上一句的介绍The terms"snowblind"and"snow blindness"have become popular because snow is highly reflective of ultraviolet radiation可知,这个术语很流行,因为雪能高度反射紫外线,所以snow can reflect over 80percent of the UV rays that fall upon it这句话说雪能反射80%的紫外线,起到承上启下的作用,故选E.
38.G 上下文语境.根据后一句话Anderson Cooper experienced snow-free snow blindness first-hand a few years ago 可知,这位记者在没有雪的地方也经历了"雪盲",可见,水和白沙也有反射紫外线,增加了这种风险,故选G.
39.D 细节题.从句sun lamps can cause temporary"snow"blindness if proper eye protection is not used.
可知,太阳灯也能造成暂时的"雪盲",推出一些人造的东西也能反射紫外线,故选D.
40.F 概括题.根据这段的内容介绍可知,主要介绍了几种减少"雪盲"发生的方法,故选F.

16.Most students are also workers in colleges around the country.
The reality of college can be pretty different from the images presented in movies and television.Instead of the students who wake up late,party all the time,and study only before exams,many colleges are full of students with pressing schedules of not just classes and activities,but real jobs,too.
This isn't a temporary phenomenon.The share of working students has been on the rise since the 1970s,and one-fifth of students work year round.About one-quarter of those who work while attending school have both a full-course load and a full-time job.The arrangement can help pay for tuition and living costs,obviously.And there's value in it beyond the direct cause:such jobs can also be critical for developing important professional and social skills that make it easier to land a job after graduation.With many employers looking for students with already-developed skill sets,on-the-job training while in college can be the best way to ensure a job later on.
But it's not all upside.Even full-time work may not completely cover the cost of tuition and living expenses.The study notes that if a student worked a full-time job at the federal minimum wage,they would earn just over $15,000 each year,certainly not enough to pay for tuition,room,and board at many colleges without some serious financial aid.That means that though they're sacrificing time away from the classroom,many working students will still graduate with at least some debt.And working fulltime can reduce the chance that students will graduate at all,by cutting into the time available for studying and attending classes.
There is little reward for attending but not finishing college.Students who wind up leaving school because of difficulty in managing work and class are likely to find themselves stuck in some of the same jobs they might have gotten if they hadn't gone at all.The difficulty of working too much while in school can create a cycle that pushes students further into debt without receiving any of the financial or career benefits.

A.they throw parties a lot                                       
B.they stay up late every night
C.they pay no attention to exams

30.What is the indirect cause of an increasing number of working students?C
A.The need of developing social networks.
B.The lack of summer jobs for young adults.
C.The chance of finding a job after graduation.
D.The expenses of high tuition and living costs.
31.We can learn from the passage thatD
A.working students are more likely to finish college
B.students can cover their college expenses through working
C.students working full time will not graduate at all.
D.dropping out of college may not help students get career benefits
32.What is the best title for the passage?B
A.The Difficulties of Landing a Job                          
B.The Struggle of Work-School Balance
C.The Reward of Working While Studying                
D.The Images of Working College Students.

A School That Can Educate Us All
Christos Porios,16,lives in a small Greek city."My mother's a teacher and my father's a mechanic,"he explains,adding that neither is knowledgeable about computers-especially compared with him.(67)C
Porios was taking a free class in machine learning offered by Andrew Ng,a professor at Stanford University,over an online platform Ng developed with his colleagues.Drawing on what he learned,Porios was able to participate in the International Space Apps Challenge,a virtual hackathon (编程马拉松) using data from NASA and other government agencies.
If one teenager in one small city can become a genius hacker through an online course,does it mean the world has changed?We have been hearing about the potential of online education for decades.
(68)A A number of online education platforms have appeared,featuring professors from top universities offering free courses.
(69)F Ng was amazed."It would take me 250 years to teach this many people at Stanford,"he says.And so,just one month into the course,Ng and his Stanford colleague,Daphne Koller,decided to leave their faculty posts (教职) and dive into online teaching full-time.In April,they launched their company,Coursera,with a $16 million round of venture funding.So far,it has managed to team up with 35colleges in nine countries.
To Ng and Koller,Coursera's mission is simple and yet grand.That is to teach millions of people around the world for free,while also transforming higher education.
According to Ng,the world's top 20universities enroll only about 200,000 students.There are million more who could participate in classwork at the higher level,but most of them are far from any of the leading universities.(70)E
Koller says Coursera's total registration has hit 15 million.Porios,the young Greek,is only one of those registrants.His hope is to study in Germany or England someday.He is even toying with the idea of taking classes at MIT or Stanford-but this time in person.
