We all need cash in order to live our lives. ...

We all need cash in order to live our lives. However, something called digital currency (数字货币) is slowly taking the place of cash. "Digital currency" means money that only appears on computers.

Lots of people have digital currency accounts (账户). They use a credit card to change their real money into digital money, and then the money goes into the digital currency account. A lot of people wonder, "Why in the world should I change my real money into digital currency?" This is a fair question, but there is a good answer. If you want to buy something online, then you usually have to use digital currency.

Many people still don't trust digital currency. Some people think that if they can't hold their money in their hand, then it doesn't seem real. These people don't feel comfortable when they see numbers on a computer screen. The computer tells them that their money is safe but these people don't really feel safe. Another problem is security (安全). There are hackers all over the world. A hacker is a person who steals computer information. If a hacker gets the password of your digital currency account, he or she can steal your money.

You have to decide whether or not you trust this new invention. Just remember one thing: If you want to buy something online, then you probably won't have a choice. You'll have to use digital currency.

No matter who you are, you need sleep. 1. While sleeping, the body recovers and rests. Throughout the day, we push our bodies to work as much as we need. At night, sleep allows our bodies to return to usual state. Our organs take turns resting, and our bodies fight off illness. In addition, our brains create dreams so that we can let go of mental stress. However, not everyone is able to sleep soundly.

2. They can be caused by physical problems. Some sleeping disorders are serious enough to interfere with normal body functioning. The most common one is snoring. In fact, everyone at some point in their lives snores.3. Therefore, when air passes through the smaller opening, it causes the throat to vibrate, which in turn leads to snoring. Snoring is not a serious problem, but it can disrupt the sleep of the snorers and their bed partners.

Other sleeping disorders that are often mentioned are sleep without breathing, sleep-loving and being sleepless.4. It occurs when the brain fails to tell the body to breathe or something gets in the way of the throat.

Sleep-loving is a nervous system disorder that causes extreme sleepiness during the day. As a result, the person can suddenly go from being fine to being very weak, dreaming while awake, or even falling asleep.5. Like snoring, it is very common, but seriously being sleepless may even stop a person from sleeping completely and it is always dangerous. Reasons for being sleepless can be different, but whatever the causes are, learning to relax helps people sleep better.

A.Sleeping disorders are common.

B.Trouble falling or staying asleep is called being sleepless.

C.It happens when the throat is not kept open enough while sleeping.

D.It is something that all animals and humans must get in order to be alive.

E.Sleep without breathing is when someone stops breathing while sleeping.

今天生活能否没有电脑

For most people my age, it's hard to imagine life without a computer. It seems like almost everybody has one! In fact, there are 640 million personal computers in households around the world. Most people use them every day for work and play. Actually, the first personal computer was invented in 1975. Before then, people survived (生存) without computers and the Internet, so it must be possible!

I believe that there would be some advantages to life without a computer. We would probably do more exercise because we wouldn't be sitting in front of our screens all day. Maybe we would get better at remembering things because we couldn't always check facts online. I think we would also interact (互动) more with each other because computers wouldn't demand so much of our attention.

However, I think that it would also be very difficult for young people today to live without computers. We use them to communicate with our friends and family all around the world. We also use computers to research information about many different subjects. Computer technology has helped improve our lives in many different areas. For example, mechanics use computers to check our cars, doctors use computers to analyze (分析) health tests, and architects use computers to design modern, safe buildings.

All in all, I believe that, in today's society, we can't live without computers.
