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

Millions of people visit Yosemite National Park every year to see the tall waterfalls and mountains. These mountains are a splendid sight when viewed from the valley floor. Lots of stores, hotels, and restaurants are needed to handle the crowds. Also, water, roads, and other service systems are part of the infrastructure（ 基础设施）that must be maintained.

Unfortunately, these systems are starting to break down. It is not just in Yosemite but in national parks around the nation.

Yosemite is thirty years old according to Dennis Galvin, a National Park Service worker. The park is not only old but worn out. Two or three times as many visitors come every year. That is too many visitors for the park to deal with.

Four years ago a storm washed out a water pipeline in the Grand Canyon. The National Park Service had to send water trucks to provide water for the visitors. Last month pipe almost broke again and roads had to be closed for a while.

Why hasn’t the National Park Service kept up the park repairs? There is lack of money. The United States has 378 mountains, parks, and wilderness areas. Between three and four billion dollars are needed for repairs.

Yosemite is one national park that does have money fro repairs. It has two hundred million dollars but cannot spend it any way it chooses. When the park workers started widening the road, they were forced to stop by the Sierra Club. The club claimed that the road work was damaging the Merced River that runs through the park.

A Sierra Club lawyer, Julia Olson, feels that the infrastructure needs to be moved out of Yosemite. That way less pressure will be put on the already crowed park.

1. According to the text, the mountains in Yosemite look most splendid when

they are appreciated from _______ .

2.National parks like Yosemite in the U.S. find it increasingly difficult to

meet the need of visitors because _______ .

3.The main problem of Yosemite Park is its ________ .

4. According to the text, the Sierra Club is most likely to be _______ .

New rules will let millions of Americans know where more of their food comes from. The law is known as COOL -- Country of Origin Labeling(标签).

American congress first passed the law in 2002. Stores have had to label seafood by country of origin since 2005. But industry pressure delayed other requirements until last week.

Products that must now be labeled include fresh fruits and vegetables, muscle meats and some kinds of nuts. But the rules are complex, and many foods are not included. For example, organ meats are free to be labeled. So are processed foods, including cooked or smoked foods.

The same food may sometimes have to be labeled and other times not. Fresh or frozen peas, for example, have to be labeled but not canned peas. Foods that are mixed with other foods are also excluded. Mixed nuts, for example, do not need to be labeled. The same is true of a salad mix that contains different things like lettuce and carrots. Or a fruit cup that combines different fruits. Also, the law doesn’t include restaurants and other food service organizations. Department of Agriculture officials say the law is really meant for larger grocery stores.

The United States has imported more and more food in recent years to save money and expand choices. Country-of-origin labeling has become more common lately but has still been limited in many stores.

Food safety is one reason why some shoppers pay close attention to where foods came from. For example, when a large number of people recently got sick from salmonella(沙门菌病), officials blamed peppers from Mexico. Yet the last big food scare involved spinach grown in California. But labeling is also a way for people to know they are getting what they want. Some want to buy local foods or foods from a particular country.

The country-of-origin labeling law gives stores 30 days to correct any violations(违反) that are found. Stores and suppliers that are found to be deliberately violating the law could be fined 1,000 dollars per violation. Federal inspectors are not to take action to enforce the law for six months to give time for an education campaign.

Some food safety activists say they are generally pleased with the law. They call it a good step that will give people more useful information.

1.Why has more and more food been imported to the United States in recent years?

A. It is economical and provides people with more choices.

B. Foreign food is of higher quality than native food.

C. Americans need more and more food recently.

D. The United States is short of food supply.

2.Consumers are more concerned about where foods come from because________.

A. they are curious about the origin of the food.

B. most of them are particular about the tastes

C. they are concerned about food safety

D. most of them are food safety activists

3.The new rules of the country-of-origin labeling law will come into effect________.

A. right now          B. in a month       C. in three months       D. in half a year

4.Which of the following can be inferred from the text?

A. Store owners are most likely to be the supporters of the law.

B. The government of America will possibly forbid importing peppers from Mexico.

C. Federal inspectors couldn’t take measures to enforce the law.

D. Most Americans prefer imported vegetables to the vegetables grown in local places.
