1 . Are you relatively skinny but growing a “beer belly”?

Then don’t be surprised at your next checkup if the nurse measures your waistline to determine your healthy weight. That’s because research is showing that a protruding (鼓出的) belly may be a sign of VAT — a dangerous form of fat around organs deep inside your body. “Studies confirm that visceral (内脏的) fat is a clear health risk,” said Dr. Tiffany Wiley, a senior expert at the National Institutes of Health in Bethesda, Maryland. Unlike the fat just under your skin, visceral fat raises your risk for heart disease. Experts think that’s because visceral fat raises blood pressure and inflames (使发炎) tissues and organs.

However, you can’t assume you’re safe from visceral fat if your overall weight is healthy, experts stress. That’s because you can have dangerous visceral fat even if you’re not considered overweight — and not have any visceral fat even if you are overweight.

How do you know if your stomach is protruding into dangerous size? Do a check. Non-pregnant women with a waist size greater than 88 cm and men with a waist larger than 102 cm, are at higher risk according to the US Centers for Disease Control and Prevention. If you’re Asian, it drops to 80 cm for women and 90 cm for men. But it is only a rough measure. “The only sure way to know is to check your visceral fat levels on a CT scan or MRI,” say experts.

According to the AHA committee, the most salutary physical activity to “shrink” belly is aerobic exercise. Aerobic means “with oxygen”, so aerobic exercise increases your breathing rate and promotes the circulation of oxygen through the blood. This type of exercise makes the heart work more effectively and improves its ability to move oxygen-carrying blood with every beat. Speed walking, jogging, stair climbing, cycling and swimming are all examples of aerobic exercise.

“However, more studies are needed to determine the best physical activity, food and other lifestyle changes to reduce heart disease risk,” Dr. Tiffany Wiley added.

A New Addition to the Family

For the initial ten years of his life, Victor was the prince of the household. As he was an only child, his parents petted him and showered all their love and attention on him. Whatever toys his parents bought, they were always meant for him. Whatever food was in the refrigerator, there was no one to compete with him to polish it off first. Victor could leave his toys or books around the house with complete ease of mind, knowing that there was no one who would get their hands on his belongings and cause any damage.

However, all that was to change overnight when Victor’s parents brought back his new baby sister, Lina, from the hospital. With her rosy cheeks, wide open eyes and angelic smile, Lina caught the hearts of her parents, grandparents and relatives. Everyone focused their attention on the cute bunch of joy. Whenever she cried, her mother or father would rush to her bed. She simply cried because she wanted to be carried. There was little time left for Victor.

Now that Victor’s mother had his baby sister to take care of, she expected Victor himself to do most of the chores he can do. Victor was asked to clean his own room, iron his own school uniform and clean his own shoes. Before Lina’s arrival, he had never lifted a finger to help out with these tasks. The whole family also went out less because it was unhealthy to expose Lina to the bacteria(细菌) being in the outside world too often.

Victor felt neglected by his parents. He felt that they loved Lina more than him. As a result, he tried to attract his parents’ attention by becoming resistant. One evening, Victor’s parents were called up by his teacher because Victor had got into a fight at school. His teacher had noticed Victor’s behaviour and work attitude changing downwards in the past two months. Before that, he had been a model student.

9 . You probably take many steps to protect your computer from getting a virus, but what about your cell phone? Cell phones are basically mini-computers, so, believe it or not, they too can get viruses.

“Viruses and malware（恶意软件）should not be a major concern to the average consumer who uses their device to make phone calls, take pictures, and download a few well-known apps from the major app marketplaces,” Tim Katsch Vice President of iDropped said. “If a user is downloading a lot of apps, changing and exploring settings within the device, and visiting a large number of websites from unknown sources, virus and malware protection should be kept on their mind.” If your phone gets a virus it can mess up your data, put random charges on your bill, and get private information such as your bank account number, credit card information, passwords, and your location.

The most common way that you could get a virus on your phone would be through downloading an infected app. Viruses can also get on your phone when you click on strange links or open up an email that contains a virus. Connecting to an unsecured wireless network in a public place is also a way for hackers（黑客）to get private information from your device.

If you're still convinced that your phone might get a virus, there are anti-virus apps that you can download that will constantly scan your phone to make sure it hasn't developed a virus, Apps like these will also check things before you download them to ensure that they are safe. Another tip is to always look over your cell phone bill every month to make sure there aren't charges from apps that you never downloaded.

Technology is getting smarter, but so are hackers, and it's important to always be cautious with anything you do on your phone. Many people store a lot of personal information on their phones, and while that might make life a little more convenient, it can also do a lot of damage if hacked.

1. What can we learn from Tim Katsch's words?

A．The wireless network in the public places is safe to use.

B．Viruses and malware will most probably attack average phones.

C．Downloading a lot of apps will protect your phone from being hacked.

D．The average consumer needn't worry much about a virus or malware.

2. What's the most common way that your phone gets a virus?

A．Downloading an infected app.
