EVERY YEAR, millions of Americans see their personal information leak into the wrong hands. Maybe there’s spyware on their computer, or a service they use suffered a security reach --- as eBay did this year, leaving customers at risk of exposure. Or perhaps their password is easy to guess: Security company SplashData reports that the most popular passwords in 2013 were 123456 and password.

Fear not: It is a lot easier than you might think to set up proper defenses. In fact, you can easily do it all in a weekend. Here’s how.

Clean Your Computer And Smartphone

Before you put new security measures into place, make sure your devices are as spotless as possible. This means installing a good antivirus program and taking the time to clear out any spy- or malware that may have already infected your system. Go with AVG Free Antivirus (free. Avg. com) or Avast! (avast. com) ---each is free. Run a full system scan. This can take over an hour, so start it before settling into other plans. When you return to your computer, clear out anything that shouldn’t be there with a few simple steps (the program will guide you). These days, it’s also worth it to make sure your phone is safe from viruses. iPhones are less likely to be targeted by spyware, but Android users should download the Lookout app (lookout. com) to scan their devices and ensure everything is as it should be.

Security Your Wi-Fi

Now that your computer is clean, you should plug any holes in your home network. It’s fairly easy for potential criminals to gain access to your information if they’re able to share your connection --- that’s why you want to be careful when using public Wi-Fi. For your home, the Federal Communications Commission recommends a few steps. Even though you put security measures into place a couple of years ago, it’s a good idea to refresh your settings. You may have to refer to the instructions for your wireless router or call tech support for help. Different routers will have different setup pages, so the actual step-by-step will vary, but the end result will be the same.

Dig Deep with Your Passwords

Everything you just accomplished could be for nothing if a thief has your existing passwords, so you need to change them for every service you use. Try it when you find yourself on those sites anyway.

What you’ve heard is true: Passwords should use a variety of special characters, numerals, letters, and cases when possible. They should be close to random, and there should be a different one for each website you use. Doing this, and keeping track of it all, is a pain --- which is why people don’t do it and wind up with stolen identities. Try Dashlane (dashlane.com), a password manager with powerful encryption (加密) that can securely keep track of the most ridiculous codes you can come up with. Best of all, it logs you into sites automatically, so there’s no need to worry about all those obscure keystrokes. Whew!

Never Answer Unwanted Email

Take are when shopping online. Always check the security symbols when using an online site for shopping. If the lock icon encryption is not there, do not give out credit details. Also, check that the site is legal --- never go to a site from a random email and start shopping online. Go to the site through a known URL or by searching for it on a search engine first.

Keep a separate credit card just for online shopping. This will make it easier to cancel if something bad does happen and your other credit card for “in real life” can still be used uninfluenced.

Don’t store information on any store’s website. It may be conventional but it’s also a possible loss to you if the site is hacked.

1.The passage is mainly about _____________.

A. ways of avoiding online identity theft

2.According to the passage, the risk of exposing personal information may possibly be caused by ___________.

Four Simple Keys to Transform Your Life

The Power of Choice．Every one of us makes countless choices every day．Every choice we make has an impact on our lives．Even insignificant choices can affect what we experience and how we feel．When hunger strikes, we can reach for a healthy, nutritious snack, or we can choose the sugar high of junk food．The more important the decision, the greater its effect．For instance, how do I act towards that person who treated me badly? Do I generally choose to be passive, or do I actively set clear intentions and create what I want in my life? Every choice we make, however big or small, affects us in some way．

How Do You Make Choices? If you are interested in living a richer, fuller life, there is a foundation upon which you can base all of your decisions which can make life better not only for you, but also for those around you．This foundation is to choose based on what's best for all．Imagine a world where every parent, spouse（配偶）, friend, teacher, business person, and politician truly did their best to choose what's best for all involved in every decision they made. We would certainly live in a more caring, supportive world．

It's the Intention．"But how do I know what is really best?" you might ask．The answer is simple．It doesn't matter．What matters is not the choice you make, but rather the intention beind your choice．What matters is that whatever decision you make, you are clear in your intention of choosing based on what's best for all．If it later turns out that you made what appears to have been a bad choice, there's no need for guilt．Knowing that you did your best to choose with a sincere desire for what's best for all, your conscience stays clear and open．This then allows you to more easily learn from your mistakes, and to live with a clear heart and mind．

What's Best for Me, Too! Choosing what's best does not mean you have to always sacrifice yourself for others．An overly(过度的) exhausted mother can lose her temper easily．Some time off for this mother might seem selfish, yet in the long run, it can help her to be a better mother to her children．So as we move through each day of our lives, let us remember to include ourselves as we do our best to choose what's best for all．

1.Which of the following is FALSE?

A．Whenever hunger strikes, we will reach for a junk snack

B．Every choice, however big or small, has an influence on us．

C．Even small choices affect how we feel．．

D．We make choices every day．

2.How should we make choices?

A．To be interested in a richer, fuller life．

B．To make life better for ourselves．

C．To imagine a world where everyone did their best．

D．To choose based on what's best for all．

3.Why does the author say, "What matters is not the choice you make, but rather the intention behind your choice．"?

A．Because the choice you make is not important．

B．Because you may have made a bad choice．

C．Because this allows you to stay clear and improve．

D．Because there is no need for guilt．

4.How to choose what is best for us?

A．We need to devote all our life to others．

B．We need to put away some time for ourselves．

C．We need to sacrifice ourselves for others．

D．We need to be selfless every minute．

Feb. 29, or Leap Day, arrives on your calendar once every four years—and 2020 is one of them.

You may have heard of the American Dream, an ideal that has powered the hopes of Americans for generations.

It began as a belief that the US was a land of opportunity, and that anyone could achieve success through hard work. At times, the dream has referred to home ownership, a good job, retirement security or each generation doing better than the last.

Yet today, this concept seems to have greatly changed. As Time magazine pointed out, quite different from the older generation, many Millennials (the generation born after 1980) redefine(重新定义) the American Dream as “day-to-day control of your life”. They “prize job mobility, flexible schedules, any work that is more interesting than typing, and the ability to travel”, said the magazine.

Home ownership, once the cornerstone of the American Dream, is becoming a smaller priority for this generation. Meanwhile, nearly 40% of them choose travel as part of their dream. And entrepreneurship(创业) is a rising favorite, as nearly 26% of Millennials consider self-employment as part of their dream.

So what has led to this huge change?

Many point fingers at the poor economy. “Modern young Americans seem bound to face a world stamped by ever narrowing opportunity and social stagnation(停滞),”noted The Daily Beast.

“The rate of 16-to 24-year-olds out of school and out of work is unusually high at 15%. Many college graduates have taken jobs that don’t require a degree,” Time reported.

The magazine worries that these difficulties may lead to a lost generation who are “unable to ever truly find their feet on the corporation’s ladder”.

Dan Kadlec, a reporter of Time, sees Millennials as resetting their expectations.”This situation is different for young adults today,” he wrote. “A true American dream has to feel attainable, and many Millennias are feeling they can only attain a day-today lifestyle that suits them.”

1.The underlined word “cornerstone” in Paragraph 4 is closest in meaning to “　　　　 ”.

A. growth　　　　　 B. balance　　　　　 C. basis　　　　　　　 D. purpose

2. What has changed Millennials’ view of the American Dream according to the passage?

A. A lack of confidence in themselves

B. Fierce competition in the job market

C. Their dissatisfaction with the government

D. The discouraging economy and unemployment

3.Dan Kadlec thinks Millennials’ new definition of the American Dream is ______.

A. beautiful　　　　　　 B. understandable

C. worrying　　　　　　　 D. positive

4.What can be the best title for this passage?

A. Redefinition of American Dream

B. Meaning of American Dream

C. Value of Achieving American Dream

D. History of Changing American Dream
