5.By today's standards,my mobile phone is pretty rubbish.It's a Nokia 1616.If that doesn't mean much to you  ( it's not the kind of phone you see advertised on television),all you need to know is that it's a small,not very heavy device with which you can send and receive telephone calls and text messages.It also has a very handy torch on the top for when you can't find your keys,or when you drop something on the floor in the cinema.Other than that,my phone doesn't do much.Well,it has an alarm,and it probably has a calculator and things like that,but it's nothing compared to a smartphone.Why would I want one of those?
I have often been told that the big advantage of having a smartphone is that"you can do everything with them!"But when was the last time you saw someone doing"everything"with a smartphone?Okay,so they may have an endless list of functions,but generally they are used for checking social networking sites,playing games,and receiving and replying to emails.I'm happy just doing all of those things at home on my laptop.
As far as I can tell,the best thing about having a smartphone is that you can be connected to the inLernet all the time.Don't get me wrong,I love the internet,but I just don't see the point of constantly being online.I can't remember the last time I received a Facebook update which was so very urgent that I had to read it as soon as it appeared,and I can't imagine ever having a job which
was so important that I would need to read work-related emails immediately.I would think that if someone needed me urgently,they would just ring me rather than send an email.And my trusty Nokia can manage that.
One of the most peculiar effects of the smartphone is,in my opinion,the newly-found addiction  to maps and navigation (導(dǎo)航) systems.Is there anything more boring than knowing exactly where  you are all of the time?!How do you get to know an area if you don't get lost there a few times?And  if you are dependant on online maps,what happens to those great places you find just by chance?You can't exactly find out from google maps the journey from"here"to"that hidden cafe with the  tasty-looking cakes",or to"that pond next to the church which looks really pretty in the evening  sun."It is,of course,true that we all occasionally need to be pointed in the right dircction,but I  find that there are often real life  humans you can ask.
There are many benefits of having a very basic mobile phone,like the face that it cost me about twenty pounds,and that I don't have to worry too much about it being stolen.But the main benefit.has to be the fact that it provides me with the word'greatest excuse for my bad habits,Whether it's turning up late to events,or getting lose on a trip,or missing buses or trains,or forgetting about an  appointment at work,I'm pretty sure I'm covered with the following explanation"I'm really,sorry I don't have a smartphone."

41.The writer uses his Nokia 1616mainly toD.
A.play online games                   B.do calculating work
C.check social network sites          D.make calls and text messages
42.It can be inferred from the above passage thatB.
A.work-related emails should be answered immediately
B.a(chǎn) laptop and a smartphone share many functions
C.smartphones should always be connected to the net
D.a(chǎn) Facebook update is usually very import
43.According to the passage,if you use navigation systems,you mayA
A.miss some really wonderful places            B.find a boring trip actually exciting
C.be persuaded to eat in a certain cafe        D.be misled to a totally wrong place
44.To the writer,one benefit of having a basic mobile phone is thatC
A.it can remind him of important appointments
B.it can often be found back after it is stolen
C.it can be used as an excuse for his bad habits
D.it can save him the trouble of catching trains
45.The writer's purpose for writing this article is toA.
A.explain why he doesn't want a smartphone
B.warn readers of the risks of using smartphones
C.complain about the troubles caused by smartphones
D.inform readers of the latest development of mobile phones.

  After working in the business world for a while,Low got fed up.So she turned to teaching at a technical school and later moved into the library.
  Low's mother liked reading.As her eyes began to fail,low read to her.Then"hearing an advertisement encouraging people to learn Braille,I decided to give it a try."In 1973,she was certified as a braille transcriber (轉(zhuǎn)譯者) and began transcribing books as a volunteer for the CNIB library.
  The job was strenuous---she could get to the end of a page,make a mistake on the last line,and have to do the whole thing again.For a number of years,low also worked in the CNIB sound studio reading books onto tape.Three years ago,she took up proofreading (校對) at the CNIB's word factory.
  In April,during Volunteer Week,the CNIB recognized Low for her great contributions.Thanks to volunteers like Low,the CNIB library has got more than 80,000accessible materials for people unable to read traditional print."I can't imagine how many readers of all ages have benefited from
  Doris's contribution as a skilled volunteer through her rich voice and her high degree of accuracy in the hundreds of books she has brailled and proofread over the years---and she is still doing so,"said a CNIB official.
"For me,"said Low,"the CNIB is more than just a place to volunteer.Three thins matter most in my life:a little play,a little work,a little love.I've found them all here."

56.What does Low still do at the age of 90at the CNIB?( no more than 10words)
57.why did Low learn Braille?( no more than 15words)

13.Singapore was just a sleepy city in Southeast Asia more than 50 years ago.But the small dot on the world map has since developed into one of the richest nations thanks to its founder and first Prime Minister Lee Kuan Yew,the father of the state,who passed away on March 23,2015at the age of 91.

To the world,Lee was one of Asia's most popular politicians.He was one of the first to spot the potential of China under a former leader Deng Xiaoping and contributed to China's reform and opening up."No small number of this and past generations of world leaders have asked for his advice on governances and development,"said US President Obama."Lee is a visionary and a true giant of history."
