Ebola is a dangerous virus that can cause people to get very sick and even die. The virus is causing the biggest problems in western Africa, where it has spread quickly. {#blank#}1{#/blank#} But it can get worse and cause life-threatening symptoms(症状), such as bleeding and trouble breathing.

    {#blank#}2{#/blank#}

    Ebola does not spread like colds or the flu because it does not float through the air. Ebola also doesn't spread through food or water, like some other viruses. Instead, Ebola spreads when someone touches the body fluids(液体) of a sick person.

    An outbreak is when many people are getting sick with the same illness around the same time.

How to Protect Yourself from Hackers Online

    An increase in cyber-attacks (网络攻击) makes the Internet seem like a scary place these days. How can individuals protect or make it more difficult for hackers to access their information? Here are several tips that can help you protect against cyber-attacks:

    {#blank#}1{#/blank#}

    Hard passwords include upper and lower case letters, numbers and special characters. They should be at least eight characters in length. They should also not spell out words easy for hackers to find, like your pet's name or the name of a family member.

    Change your password regularly

    A very common mistake made by users is to create one hard password, but then never change it. Remembering a long list of complicated passwords can be difficult. But no password is unbreakable. Hackers are better able to hack multiple accounts if those accounts all have the same password. A password management service, like Dashlane or PasswordBox, can help you keep track of hard passwords. {#blank#}2{#/blank#}

    Clear your browser (浏览器) history

    This goes for all the devices you use in a day – your home computer, your work computer, or your friend's iPad. Internet browsers like Firefox or Chrome keep track of where you've been and what you've done online. They keep records of every site you visited. {#blank#}3{#/blank#} It is very easy for anyone who sees that information to steal a detailed record of your online activities.

    Do not use free Wi-Fi

    {#blank#}4{#/blank#} Often, a user does not need a password to connect to these wireless networks. These services might be useful, but they're also an easy way for hackers to access everything on your device.

    Use anti-virus protection

    There are many anti-virus services available for users. {#blank#}5{#/blank#} Some anti-virus services are even free. They are a great way to have a professional help keeping users one step ahead of hackers.

A. Be careful while using thumb drive.

B. These services permit users to easily store and secure their passwords.

C. Make your password harder to hack.

D. They can offer many different types of computer protection.

E. An increasing number of public places now offer free wireless access to the Internet.

F. Information about what you sent from or saved on your computer can be kept for days or weeks.

G. Unless you really need it, it is best not to use it.

    You probably know that exercise is the key to reducing depression, but you might not know why. Here are some tips for exercising when you're depressed.

    Change your view of “exercise”.

    Forget “exercise”. Instead, think “being active” or “having fun”. {#blank#}1{#/blank#} Besides, it gives you a bigger benefit.

    {#blank#}2{#/blank#}

    Taking part in physical activities with others supports you in doing those activities. Ask friends what activities they're doing or they would like to start doing, and join them. Other choices include hiring a personal trainer, joining an exercise group or going to a class.

    Try an experiment.

    {#blank#}3{#/blank#} Or go to the gym every Monday, Wednesday and Friday. Even if you're feeling too tired to do any actual exercise, still go to the gym, park your car, walk in, chage into workout clothes, and pick up a 5-pound weight. If you're really so tired that you don't want to do anything else, that's totally fine.

    Take it outside.

    Nature has a great effect on our feeling and decreases depressive symptoms. Even just looking at images of lakes and trees helps. {#blank#}4{#/blank#} Or walk on a treadmill (跑步机) by a window.

    Tie it to a goal.

    Korb said, “When you connect your exercise to a long-term goal, it helps your brain forget momentary discomfort and makes your exercise more satisfying.” For example, Korb started getting active because it made playing sports more enjoyable. Figure out what's truly important to you. {#blank#}5{#/blank#}

A. Move with someone else.

B. Sign up and go to exercise classes.

C. It's a lot easier to do something simple.

D. Remind yourself of your goal regularly.

E. Remember your partner to keep you company.

F. Take a walk around your neighbourhood or a local park.

G. This increases your chances of actually moving your body.

    How old is "old"? {#blank#}1{#/blank#} Two hundred years ago, you were old at 35. That was the average life then. At the turn of this century, as medical knowledge advanced, the average life span(长度) increased to 45. In 1950, 70-year-olds were really old. Today, a healthy 70-year-old is looking forward to many more active years.

    So, how old is old? The answer is one you've heard many times, from all sorts of people. "You are as old (or young) as you feel!" The calendar(日历) simply tells you how many years you have lived. {#blank#}2{#/blank#}

    Once an unknown author wrote, "{#blank#}3{#/blank#} Nobody grows old by living a number of years; people grow old by giving up their goals."

    {#blank#}4{#/blank#} Alice Brophy, when she was with the New York City commission for the Aging, said, "It upsets me when people say, 'Gee, you look young for your age!' What does that mean? Is there some model that you're supposed to look a certain way at 65 and 75 and 85? You know you can die old at 30 and live young at 80"

    There are many wrong ideas about aging. {#blank#}5{#/blank#} Here are some of the more common ones. For example, most older people are in poor health, or older people are unable to change.

A. The answer has changed over the years.

B. Old is a point of view.

C. Older people are stubborn, unable to change.

D. Youth is not a time of life but it is a state of mind.

E. These ideas stereotype (固化) people on the basis of age.

F. Your body tells you how well you've lived.

G. It's extremely terrible to be grown old.

    Vacations are important. We need to take time out from work to relax, and just be ourselves. {#blank#}1{#/blank#} We should all be allowed to leave our jobs behind us—at least for a few weeks each year—and just have fun. This might be something as simple as reading a good book in front of a warm fireplace and travelling to the most interesting places on our planet. Whatever we fancy doing is worth taking time out for.

    Workplace stress is on the rise. {#blank#}2{#/blank#} These include disease, depression and even death. We all seem to be running from one place to the next, never finding out where we want to go in the first place. I intend to break that trend in the coming days.

    {#blank#}3{#/blank#} I will sleep late, write, watch movies, drink the occasional glass of wine, and eat to my heart's content ignoring calorie counting. My plan is to just enjoy the fleeting moments of being alive.

    {#blank#}4{#/blank#} Spend your next vacation the way you want. Do what will restore your mental health. You're very valuable to the people who are close to you, and to those who depend on you. Like it or not, we are all interdependent in this great life of ours.

    You are valuable. Just remember that the next time you look at the mirror and take a deep breath. Remind yourself that there will never be anyone like you ever on this earth again.

    {#blank#}5{#/blank#} All you have to do is just ask yourself what you want to do.
