It is advisable to attach a radiation filter plate (辐射过滤板) in front of your computer's screen.Make sure to avoid putting any metal substances near your computer as these may have reflected some of the electromagnetic waves that are harmful to your health.(18)AThe brighter the screen the higher the radiation there will be and vice versa.
You can also put some radiation-absorbing plants such as several cacti near your computer to prevent radiation.
Make sure you do a skincare protection before sitting in front of the computer.(19)BWash your face soon after using the computer in order to reduce 70% of the radiation.

分析 本文介绍了几种减少电脑辐射的方法.

解答 16.E 考查上下文联系.根据下一句Green tea can be absorbed by the body easily into a form of vitamin A,which helps reduce radiation可知本段是关于用绿茶来减少电脑辐射的影响,故E项正确
17.G 考查前.后逻辑.绿茶还有另外的功能就是提高视力,故G项正确
18.A 考查上下文联系.根据下句The brighter the screen the higher the radiation there will be and vice versa.说明屏幕的亮度也是影响人们视力的原因,那么就要调整屏幕的亮度.故A项正确.
19.B 考查上下文逻辑关系.根据下一句Wash your face soon after using the computer在用完电脑以后要洗脸.那么之前也要采取措施,选项中只有B项是与之有关的.故B下符合上下文.
20. F 考查上下文联系.根据下句Old computer in general,has one to two times more radiation released than the new one within the same distance.说明旧电脑的辐射较大,那么应该使用新的电脑.故F项正确

13.A busy public square in the Chinese city of Nanjing is home to an unusual experiment.
For almost two months,the country's first"honesty bookshop"has occupied(占据)a sidewalk on HanZhong Road in the city's Gulou District.
With no cashier or other staff,the store relies on trust for payment.
Making money isn't the company's main goal and they don't punish those who take books without paying.
"If they can really finish the books,it doesn't matter if they took the books for free,"Zhu Yu,the marketing director of the company says.
"In fact,we are really happy to witness so many people taking books from the honesty bookshop."
After browsing the four wooden bookshelves,customers must drop their money in a locked box.
Prices are set at 30% of the usual cover price.
Zhu hopes that his sidewalk store,which sells,on average,60books a day,will make more people interested in reading.
Like elsewhere,e-books are affecting sales of traditional books,And traditional books and many independent booksellers are struggling.
Zhu got permission from the city government to use the sidewalk and says he's determined to make it a long-term project.
He says the store is open every day,except when it rains,and it's locked up each night.
In September last year,the company laid out 1,000books and reading lamps on the ground and encouraged people"to go on a date"with a book.
"Independent bookshops represent the well-being of the city."Zhu told CNN in 2013,"when a city is losing its bookshops,it's actually losing something in its soul."
If the success of the Honesty Bookstore is any guide,Nanjing's soul is in pretty good shape.
21.How is the bookstore different from other bookstores?A
A.There is no cashier in it
B.There are no paper books in it
C.None of the customers need to pay for the books
D.Only honest customers can visit the shop
22.What does Zhu Yu say about customers who take away books without paying?C
A.They will be forbidden from visiting the bookstore again
B.They will have to pay a lot of money next time they visit the shop
C.They are not doing wrong if they finish reading the books
D.They will not be allowed to take books away next time
23.What is one of the purposes of opening the bookstore?A
A.To encourage people to read
B.To make customers honest
C.To check whether customers are honest
D.To help people learn about Nanjing
24.What can we learn from the text?C
A.The shop is only open on weekends
B.The books in the shop are more expensive than shoes in other shops
C.30% of the normal cover price is charged for each book
D.The shop is not locked at night.

6.Archaeologists searching for a lost city in the forests of Honduras have discovered the urban remains of what they believe is a vanished (消失的) ancient civilization.A writer and photographer for a magazine accompanied a team of scientist to Honduras'Mosquitia region reporting a legendary"White City"or"City of the Monkey God."
The expedition was made after aerial light diction scanning(机载激光雷达检测)-known as LIDAR-uncovered what appeared to be man-made structures below the rainforest.Seeking to confirm the discovery,a team of U.S.and Honduran researchers entered the remote region.They were protected by Honduran Special Forces.
Writer Douglas Preston said the team emerged on February 25,after documenting the ruins of a"vanished culture.""In contrast to the nearby Maya,this vanished culture has hardly been studied and it remains virtually unknown.Archaeologists don't even have a name for it,"Douglas wrote.Archaeologists no longer believed in the existence of a single"While City,"he said,instead believing there had been an entire civilization with many cities.
The expedition found earth works,including an earthen pyramid as well as a collection of stone sculptures.Archaeologists from Honduras estimated they dated from A.D 1000to 1400.
The researchers were greeted by wildlife which appeared never before to have seen humans,wandering unafraid through their camp.This is clearly the most undisturbed rainforest in Central America.The team left their finds untouched and are keeping the exact location of the site secret in an attempt to prevent looting (洗劫).
But Douglas warned that the area was nevertheless under threat,with illegal logging (砍伐) for cattle farming within a dozen miles.A local director said that the forest and valley could disappear within eight years unless action was taken."The Honduran government is trying to protect this area,but doesn't have the money.We urgently need international support."
24.The purpose of the expedition is toB.
A.find the endangered animals      
B.make sure the existence of relics
C.stop illegal activities    
D.test the equipment
25.The team kept the exact location secret in order thatB.
A.wildlife could wander around freely
B.their finds were under protection
C.illegal farming could be prevented
D.the most undisturbed rainforest could be protected
26.What is the greatest concern for the Honduran government to protect this area?A
A.Financial problems    
B.No political support
C.An unsolved technical problem     
D.Local people's poor environmental awareness.
