Everybody Should Say Thank You to Ray TomGnson
Why should you thank Ray Tomlinson? You might have never heard of his name before，but
do you know that the e-mail you use every day was his“child"？
Ray Tomlinson is known as“the father of e-mail". He
was born in New York in 1941. He attended college at the
Renaselaer Polytechnic Institute，where he took part in a
program with IBM，and in 1963 he received a bachelor（学士）
of Science in electrical engineering.
In 1971，Ray created the first e一mail system，which allowed people to send messages electronically from the same computer. But he thought that there might also be a way to send messages from different computers，which led to the birth of the e-mail we know now. He chose
the @ sign to separate local from global emails in the mailing address.“I used the‘@’sign to show that the user was‘at’some other hosts rather than being local，”said Ray in an interview. person to person network email was born and user @ host became the standard for email addresses，as it remains today.
Ray Tomlinson died at the age of 74. Thanks Ray Tomlinson for inventing the email and putting the @ sign on the map. Though he may not be。famous as Mark Zuckerberg or
Bill Gates, Ray Tomlinson surely has his place among the geniuses（天才）that gave us the convenience that we call "computer technology"．

C
There are basically two ways of driving in the world：if the driver's seat is on the left and cars travel on the right side of the road，it is called“left-hand driving”，as it is in China；Instead，it
is called“right-hand driving”，as it is in Britain. Nowadays，around 65% of the world's
population drives on the right of the road，while the rest is
used to driving on the left.
Though no one knows the exact reasons，it seems likely
that people in ancient times travelled on the left. Roman
coins show pictures of horsemen passing on each other's
right. And right-handed people generally got on a horse from
the animal's left. Obviously，it's safer to do this at the left side of the
road，so it makes sense for the horse to be ridden on the left.
A change happened in the late 1700s. When Napoleon conquered
（攻占）nations, he forced them to travel on the right side of the road，which spread left-hand driving throughout Europe. However，Britain still stuck with the right-hand driving role and countries which were part of the British Empire were made to follow. This is wh，India，Australia and the former British colonies （前英国殖民地）in Africa continue to drive on the left. One exception is Egypt，as that country was defeated(打败）by Napoleon before becoming part of the British Empire.
Some countries changed sides' until modern times. Sweden only moved to driving on the right
I in 1967 and Iceland changed the following year. Ghana changed sides' in 1974. On September 7，2009，Samoa became the third country ever to change from left- to right-hand driving for the
reason that it made it easier to import(进口）cheap cars from right-hand driving Japan, Australia
and New Zealand.
So if you want to travel to mother country or go on business，make sure you know whether it
is left- or right-hand driving to avoid unnecessary troubles.
49. Nowadays，of the world's population drives on the right of the road.
A. around 74%
B. around 65%
C. around 19%
D. around 17%
50. On Roman coins we can see pictures of horsemen
A. travelling throughout Europe
B. passing on each other's right
C. practicing riding in the country
D. getting on the horses from the right
51. Which of the following is true according to the passage?
A. Sweden changed to drive on the right in 1974.
B. People drive on the left side of the mad in Egypt.
C. Napoleon helped with the spread of left-hand driving.
D. People have known the exact masons for driving on the left.
52. What is the writer's purpose for writing this passage?
A. To explain the advantages of the two ways of driving.
B. To compare the diffemnces of the two ways of driving.
C. To introduce the development of the two ways of driving.
D. To complain about the change of the two ways of driving.
D
Do We Say What We Think?
"It's raining cats and dogs！”Although this sentence is not very common in England any
more，it clearly shows how we don't always say what we mean. One thing that often gives trouble
to language learners is that they understand every word in a sentence but the meaning remains
unclear-like this sentence that actually means“It's raining very heavily！”However, it's act just
idioms（惯用语）that cause difficulties for people learning English.
The British are often considered to be polite and keep their feelings to themselves，but this
can be very confusing for non-native speakers. We often don't say what we are thinking--in fact
we often say the opposite！Here's an example that will hopefully explain what I mean，“You
should come mund for tea！”Is this a real invitation or is the person just being polite? Generally，British people are less open than people from other cultures，so we aren't quick to invite people
into our homes. This phrase is one of those that we say but often don't really mean，so when no
further details（细节）are given，you can probably think it was made in the name of politeness！
But how does this compare to other countries?
When I lived in India，lots of people would invite me into their homes but I always assumed
that they were just being polite. Of course，I was wrong. The invitations were always from the
bottom of hearts，and they did expect me to visit them. I was always surprised by how welcoming people were. In fact，I think I spent more time at other people's houses than my own！
This summer, while working in Austria，one of my friends made me think about invitations
again. She invited me to join her and her boyfriend for a meal out. Although touched by the
invitation，I immediately had the thought that she was just being polite，so I told her that I didn't
want to interrupt them. She replied with，“If I didn't want you to come，I wouldn't have invited
you in the first place!”
This reminded me again that politeness depends on which culture we're in. In England，we
often think it's polite to offer or suggest something even if we don't actually want to do it，but in
other cultures people are more direct. Perhaps if English people just say what they were thinking，things would be a lot easier-especially for people from other countries！
53. From the passage we can learn that
A. it's impolite to invite friends to come mund for tea in India
B. the British politeness can make non-native speakers confused
C. it's only idioms that cause difficulties for people learning English
D. the British are very open and like inviting people into their homes
54. The underlined word“assumed" in paragraph 3 probably means“”．
A. imagined
B. proved
C. regretted
D. explained
55. The writer probably agrees that ．
A. people learning English should be direct to say what they think
B. different cultures lead to the different realization on politeness
C. its very necessary to learn about English idioms to be polite
D. living in Britain is more difficult than it in other countries

A Colorful World
Mr. Iangman and Mr. Martin were both badly ill 56 . Mr. Longman was able to sit up in
his bed for an hour each afternoon. His bed was next to the only window of the room. Mr. Martin
had to spend all his time lying on his back. So they talked for horns without stopping. 57 And every afternoon when Mr. Longman could sit up in his bed，he would talk about all the
things that he could see outside the window. Mr. Martin believed that his world was made“larger" by
the“colorful" outside world. Out of the window it was a park with a lovely lake. Mr. Longman told Mr. Martin about the beautiful ducks swimming freely on the water, happy children playing around，
colorful flowers and big old trees around the lake. 58，Mr. Martin closed his
eyes and tried to make the richest pictures for himself in his mind.
Days and weeks passed. Mr. Longman got better. 59 . Then Mr. Martin
asked the nurse if he could move to the other bed. Happily for him, the nurse
said he could. When everything was done，he tried hard to raise himself a
bit to see what was outside. 60，to his surpris e，he saw nothing but a wall.
Mr. Martin asked the nurse what made Mr. Longman able to see so many wonderful things outside. The nurse answered that the man wa s blind and could not even see the wall.

If you've been near a tourist attraction lately，you may have seen someo ne taking photos-
either alone or with a group of friends-with a camera phone put at the end of
a telescoping pole（伸缩杆），now commonly known as。“selfie stick".
Selfie sticks fast became popular with the young people in Southeast
Asia，including Indonesia, Malaysia, and the Philippines，followed by South
Korea and Japan. They are now widely seen across Asia and have spread to
the US and Europe. There are nearly 130,000 photos on Imtagram
（图片分享应用）taken with a selfie stick.
As you know，selfie sticks are pretty convenient to use. First you put your phone
at the end of the selfie stick. Then raise it in front of yourself and make a sound or
press a button on the stick handle which is connected to the camera, or press a button
on a wireless remote(无线遥控），or use the camera's built-in timer（内置计时器）to take a photo after a number of seconds have passed. With a perfect smile on your face，the picture you want is done！Besides its convenience，there are other advantages to use selfie sticks.
Putting more people in the frame(边框）．A selfie stick makes it easy to fit all your friends
in one shot. Nobody has to “cut" the face by half in the picture any more.
Adding backgrounds to your self ies. The selfie stick provides distance between the camera
and your subject（you！），so you can include more in your picture：the skyline behind you，an ancient building in the background or even the grassland-anything you like and want that can
make your picture special and nice.
Getting more angles（角度）．The selfie stick is easy to hold，which means you can get some
fun and creative angles-to enrich your selfies or to take interesting photos of friends.
So next time you travel alone or want to take a fun group photo，a selfie stick may help you.
61. Where did selfie sticks first become popular with the young people?
62. How many photos on Instagram were taken with a selfie stick?
63. Are selfie sticks pretty convenient to use?
