Would you tell others your QQ password (密码)? Of course not. But if your passwords are too easy, hackers(黑客) can guess them.
These days we have too many passwords to remember. To make life easy, some people use simple passwords, like123456, “888888”or “abc123”. Many also use personal information (个人信息), such as a birthday, as passwords.
But these easy passwords are not safe online. Here are some tips for a safer password.
Upper-casing (大写) your password is a good start. Put numbers and symbols (符号) in your password. Don’t use words you can find in a dictionary (词典). Make your passwords long.
For example, make a password of nine letters, with numbers and symbols in it. Then it will take hackers hundreds of years to work out!
Never use personal information as a password, Use different passwords for different things. Change your passwords every 90 days.

Step1
State the writer’s most important idea. Try your best to get the main idea according to the writer’s statements. Write down the important information to increase understanding.
Step 2
Use your own words. Imagine you are telling a friend about a great movie you saw or a great book that you read. Speak in your own language, but be sure to use standard English, not slang (俚语).
Step 3
Watch for each point and topic sentences the writer uses to support his most important idea. These points form an outline (概述) of your reading assignment.
Step 4
Pay attention to details (细节). Examine if the writer provides enough details to support his statements.Tell what those details are while writing your reading assignment.
Step 5
_________ . You should not talk about the writer’s supporting points without first talking about what those points are about.
Step 6
Try to use some words or phrases for long lists of items (项目). For example, if you see the following words: swimming, running and beach volleyball, you might just write “summer sports”.

【推荐1】Do you remember where you were when you heard about a traffic accident of a close friend? The answer is probably yes. Do you remember what you were doing on your birthday that year? You may have to think a little harder.
People remembered bad memories more easily and in greater detail than good ones. Why is that? A new study found that people do this because of evolutionary reasons.
Elizabeth Kensinger and her partners at Boston College, US, did a study looking at this. They found negative feelings like fear and sadness cause an increase in brain activity. This activity happens in the part of the brain that controls memories. So memories caused by negative feeling are kept in greater detail than other kinds of memories.
For example, after seeing a man on a street holding a knife, people remember the knife clearly, but they forget the details of the street.
According to Kensinger, it is easy to understand this from an evolutionary point of view. She said that people pay attention to dangerous information so they can use that information to guide their actions and save their lives. They can also use it to plan for similar events in the future.
The scientists say more studies are needed on how we remember, bad memories. This line of research could help solve stress disorders.

【推荐1】You pick up your phone and look at it, and the screen unlocks (解锁) right away. The phone knows who you are. It recognizes the shape of your face. This kind of face recognition technology is called Face ID. Nothing has been more simple, natural and effortless.
Actually, your face isn’t the only part of your body you can use as a password (密码). Many smartphones already accept fingerprints. Other systems check the shape of the ear, patterns in the eye, or the way a person walks. All of these are special enough to say who you are. People like using body parts as the password because it’s easy and convenient. Besides, it’s also usually very safe. It’s hard to make another person’s body parts, isn’t it? However, it is not impossible. The face may be one of the easiest body parts to copy. Most teenagers put plenty of their own photos online. These could help some bad people easily hack into a system of their phone like Face ID.
There is one more thing that worries experts. It would be easy for someone else to hold your phone in front of your face to unlock it. For example, your brother may unlock your phone against your will and see something you don’t want to show him. Some people don’t worry about that. It’s just so cool to be able to unlock a phone with a quick look.
What do you think? Is facial recognition a good thing, or are you worried about its safety?

【推荐2】On October 12, 1989, some Chinese scientists were working at the computers to look for the information they needed.
