Have you ever heard of “humblebragging(谦虚自夸“凡尔赛”)” We use it to describe someone who seems to make a modest(谦虚的) statement, but is actually trying to bring attention to something they are 1 . For example, someone might say.“I just found out that I got 2 to Harvard AND Oxford. Maybe they got my application mixed up with someone else’s!” They want to tell others that they’ve been accepted to two good schools. 3 they don’t want to seem arrogant(自大的). So instead, they word it in a(an) 4 that seems more modest.
Although people who humblebrag think it will make them seem easier to get on with, a 2015 study published in the Journal of Personality and Social Psychology showed that humblebragging has the 5 effect.
“Humblebragging backfires(产生事与愿违的结果) because it doesn’t seem very real. That ‘sadness is me attitude connected with self-promotion(自抬身价)’ does not lead to a good 6 ,” said Ovul Sezer, lead author of the study. “Even 7 bragging or complaining is better, because at least those messages are seen as more sincere(真诚的).”
Humblebragging is common and we all do it in a way Alibaba founder Jack Ma once said that his biggest mistake was 8 the company. “I never thought this thing would change my life. I was just trying to run a 9 business, and it grew so big!” he said.
Sezer said the best way to share your achievements is to “admit 10 self-promotion and win the rewards being sincere”. In this way, people will see that you aren’t just showing off and are simply being honest.

Mobile phones are one of the most useful inventions of the last 50 years, but not everything that is said about them is good. Mobiles are often believed to be the cause of a number of things from poor eyesight and headaches to house fires. There’s even one theory that mobile phones should be responsible for the disappearance of bees!
The theory is that the radiation (辐射) given off by mobile phones does great harm to bees’ navigation systems (导航系统). Bees have built-in system a bit like GPS and this helps them find their way back to their hives (蜂巢). But recently, thousands of bees have failed to find their way home. It is believed they are dying far from their hives.
The problem was first noticed by beekeepers in America and is a lot more serious than it at first seems. The important thing about bees is that most of the crops in many countries of the world are pollinated by them. Without bees, the crops can’t continue to grow. Many beekeepers in Europe have reported losing between 50 and 70 percent of their bees. Jim Piper, London beekeeper, said to the reporter, “My business is becoming wore. Twenty-nine of my forty hives are now empty.”
Nobody knows for sure whether the theory is true or not, but it’s a fact that bees are disappearing in very large numbers. And we can’t manage without them. Einstein said that if all our bees disappeared, man would only live for four more years! If the mobile phone theory is correct, we need to do something about it right now—before it’s too late.
16．What might be caused by mobiles according to Paragraph 1
A．Poor listening. B．The forest fires.
C．The disappearance of bees. D．Terrible toothache.
17．What does the theory in the passage say
A．Bees have GPS inside their bodies.
B．Mobiles have an influence on bees’ hives.
C．The radiation makes bees unable to fly.
D．The radiation makes bees lose their way home.
18．What does Paragraph-3 mainly tell us
A．Crops will stop growing.
B．Beekeepers’ business is getting worse.
C．Bees’ disappearing is a serious problem.
D．Beekeepers in Europe found the problem first.
19．The author wrote this passage to ________.
A．cull on people to help beekeepers.
B．show how a bee’s built-in system works.
C．ask people to stop using mobiles right away.
D．warn people of the possible harm mobiles do to bees.
20．In which section of the newspaper can we probably read his article
A．Education. B．Fashion. C．Science. D．Sport.
C
We are all busy talking about and using the Internet, but how many of us know the history of the Interner
Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and puter networks didn’t work well. If one computer in the network broke down, then the whole network stopped. So a new network system (系统) had to be set up. It should be good enough to be used by many different computers if a part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time.
At first the Internet was only used by the government, but in the early 1976, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software (软件) that made surfing (浏览) the Internet more convenient.
Today it is easy to get online and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students.
The Internet has now become one of the most important parts of people’s life.
