People have problems
People have to remember passwords for everything, from their email to online banking and internet shopping. 1. A leaked Yahoo database showed that the most popular passwords were still “123456” and “password”.2.
These people are trying to make life easy for themselves. 3. Hackers(黑客) have gotten very good at what they do, with more capable tools than ever, and those tools can work so well because we are still really bad at choosing and remembering passwords.
Researchers from the UK’s Lancaster University, as well as the Peking and Fujian Normal universities in China, tested passwords. 4. They guessed passwords for more than 73 percent of ordinary users, accounts. Hackers could even guess a third of the harder passwords in 100 tries, reported the Daily Mail.
According to researchers from Bloomberg Businessweek, using upper and lower cases(大小写) in your password is a good way to make is safer. Adding numbers and/or symbols to your password can also be of great help. Choose a nine-letter password that includes numbers and/or symbols; this would take a hacker’s computer hundreds of years to break, Also, never use personal information as a password. 5. Experts suggest that a user should change his or her password every 90 days to keep hackers guessing.
A. Passwords were short.
B. Use different passwords for different accounts.
C. A password must be difficult to be guessed by others.
D. Many people used simple combinations of their name, age or birthday.
E. They tried to guess passwords based on people’s personal information.
F. But they are also making it easy for hackers to break into their accounts.
G. So it’s easy to understand why many of us would pick something simple and easy for our passwords.
Recently, online hike-sharing has become the new favorite in China. In major cities, bikes in, yellow, orange, blue, white and green, can be seen almost everywhere on the street. It seems that these bikes appeared suddenly, adding a new beautiful scenery to Chinese cities.
Both the market and the public welcome online bike-sharing, but is it really a promising business? Well, it depends. After all, online bike-sharing platforms can never get away with huge operating cost and uncertain government policy.
Some theorists might say that online bike-sharing platforms can earn a fortune simply through deposit. Since users will always need to rent bikes, their deposit will always be kept to online bike-sharing platforms.
However,although online bike-sharing platforms may be able to use the deposit for other purposes at the primary stage, they will have to set up a special account, so that the deposit shall be used specially for its designated (指定的) purpose. As the market gets increasingly mature, they will have to do so whether to be responsible for users or in consideration of possible government regulations.
Now that online hike-sharing platforms can,t make profit through deposit,how can they become profitable as fiercer market unfolds? Although Hu Weiwei, CEO of Mobike, stated in an article that she would take Mobike as charitable(慈善的) project if she failed, running a startup is absolutely different from managing a charity organization. After all , she has to pay back investors’ billions of investment(投资).
To make profit, online bike-sharing platforms might have toincrease rent fee for each trip, just as Didi did
From this aspect, it might be a really good business. If we consider full screen ads fee, recommendation fee for business owners, etc. , its annual income might reach at least RMB 15 billion. If we consider the huge operation cost, including bike repairs,bikes’ service life and labor cost, there might not be much net profit left. After all, offline operation cost has always been an unbearable burden for such internet plus mode-based startups.

Science textbooks around the world have become suddenly out of date. Four new chemical elements(元素)have been added to the periodic table. A big decision now lies ahead-elements 113,115,117 and 118 need to be given their official names and symbols.
New elements can be named after a mythical(神话的) concept, a mineral, a place or country, a property(性质) or a scientist. The names have to be unique and maintain “historical and chemical consistency”. This means a lot of “-iums”.
“They’re Latinising the name,” explains chemist Andrea Sella. “The most recent tradition is to name them after places or people.” The places chosen tend to be where the element was discovered or first produced.
No one has yet named an element after themselves but many elements are named in honour of important scientists. Albert Einstein was given einsteinium. This can also be a way of righting the wrongs of the past. “Lise Meitner was really the chemist who spotted nuclear fission(核裂变)but she was never really recognised for it because she was Jewish and a woman, ” says Sella. “Giving an element a name that reminds us of her is greatly important. ”
The naming process isn’t quick. The scientists who discovered them will start things off by suggesting a name. But it will be down to the International Union of Pure and Applied Chemistry (IUPAC) to approve it. A special division of the US-based group has to accept the suggestion. Then there is a public review period of five months before the IUPAC gets the final approval. Once it’s ready, the name is announced in the scientific journal Pure and Applied Chemistry.
Naming an element is not just about functionality. Names are always important.

4.What i$ the passage mainly about?

It’s 10:00 on a beautiful Sunday morning in California. To my left is some of the most beautiful coastline. I’m walking along a road ordinarily packed with cars on days like this, but today, thanks in part to my $135 entry fee, it is closed to traffic.
There’s only one problem: I should be running, not walking. Over the past year, I’ve spent hundreds of dollars on running gear(设备) and race entry fees. I’ve jogged than 1,600 miles training for this event.
Dozens of runners pass me on either side, each of them experiencing varying degrees of sadness similar to my own. Most of them, like me, have traveled hundreds of thousands of miles to get here, spending $500, $1,000 or more to participate in this event.
Actually I’m by no means a competitive athlete. My best finish ever was fourth place, in a 5-kftometer race with only 74 participants, many of whom were walking the entire course.
Last year, over 500,000 runners completed a marathon in the U.S. alone. Nearly all of these runners had absolutely no chance of victory. The PR-personal record-is everyone’s definition of a “good race,” whether he finishes in first or 301st.
I should buy a new watch that not only tracks my location by GPS, but also by counting steps. This can more accurate and much more expensive. Finally, I have reached the finish line. I know that the official race photographers will be taking photos as I cross the line, so I raise my arms in “victory” I finish, in a time of 3:37:55, good for 354th place.
A few days after the race, the race organizers email me a link to a site where I can preview my official photos 一 and download them, for a fee, of course.
I wish I could say the feeling was unique; it’s probably not Indeed probably a feeling most runners get in most marathons. Running a lot of marathons 9 in fact, may not even be good for your health.
In America, marathoning is a rich person’s sport.
